Abstract:
This work reports and describes a novel alkali-activated metakaolin as a potential binder material for the granulation of zeolites, which are widely used as CO2 adsorbents. The alkali-activated binders are zeolite-like materials, resulting in good material compatibility with zeolite-based adsorbents. A major problem during the granulation of zeolites is that their adsorption capacities decrease by about 15–20%, because typical binder materials (for example bentonite or kaolin clay) are inactive towards CO2 adsorption. A possible pathway to solve this problem is to introduce a novel binder that is also able to sorb CO2. In such a case, a binder plays a dual role, acting both as a binding material and as a sorbent. However, it is important that, alongside the adsorptive properties, a novel binder material must fulfil mechanical and morphological requirements. Thus, in this work, physical and mechanical properties of this novel binder for zeolite granulation for CO2 adsorption are studied. Alkali-activated metakaolin was found to be efficient and competitive as a binder material, when mechanical and physical properties were concerned. The compressive strengths of most of the obtained binders reported in this work are above the compressive strength threshold of 10 MPa. The future work on this novel binder will be conducted, which includes granulation-related details and the CO2 adsorptive properties of the novel binder material. Metakaolin was used as a precursor for alkali-activated binders. Binders were synthesized using varying molarity of a NaOH solution and at varying curing conditions. The final products were characterized using density measurements, compressive strength tests, X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), Brunauer–Emmett–Teller (BET) analysis, and scanning electron microscopy (SEM).

Abstract:
This study focused on developing a new copolymer binder from Polyvinyl acetate (PVAc) and Guna seed oil, in which the copolymer binder was used to formulate an emulsion paint. The emulsion paint formulated from the novel copolymer binder of polyvinyl acetate- hydroxylated guna seed oil (PVAc/HGSO) was characterised and compared with paint made from conventional polyvinyl acetate (PVAc) binder. Seed oil from guna was extracted mechanically using cold press method, and the extracted guna seed oil were successively subjected to epoxidation and hydroxylation reaction processes. The hydroxylated guna seed oil (HGSO) was copolymerised with conventional polyvinyl acetate in different ratio of 10 to 70% of hydroxylated oil, to formulate a novel PVAc/HGSO copolymer binder. The physico-chemical properties of the formulated copolymer binder were compared with the standard value acceptable in coating industry inorder to ascertain the better blend ratio that will be suitable for paint production. The better blend copolymer binder was used in production of an emulsion paint. The physico-chemical parameters on the formulated emulsion paint were compared with paint formulated using only PVAc as a binder and acceptable value in the coating industry. The novel formulated emulsion paint found to be increased in gloss, adhesion and flexibility, which are major setback in paint produced using conventional PVAc only as a binder. Therefore, the novel PVAc/HGSO can be used to produce an emulsion paint.

Abstract:
A novel composite binder (humic acid modified bentonite, HAMB) and two other binders (bentonite and Modified humic acid, MHA) were used to explore the effects of binders on the properties of magnetite green pellets in this study. The results of green pellet properties and drying tests show that the low doses of a humic substance-based binder can achieve the same effect as high doses of bentonite binder. A humic substance-based binder could be a promising organic binder to replace bentonite. Meanwhile, the influence mechanism of adding different binders on the strength of green pellet was discussed, and the relationship between moisture content in the pellet and the compression strength of three binders was determined. A TG-DSC analysis found that the novel composite binder (HAMB) was not a simple mix of humic acid and bentonite, in which a humic substance could change the structure of bentonite and reduce the thermal stability of bentonite, causing the HAMB composite binder to have a high decomposition temperature.

Abstract:
To evaluate binding potential of Prunus domestica gum in tablets formulations. Six tablet batches (F-1B to F-6B) were prepared by wet granulation method, containing Avicel pH 101 as diluent, sodium diclofenac as model drug using 10, 15 and 20 mg of Prunus domestica gum as binder and PVP K30 was used as standard binder. Magnesium stearate was used as lubricant. Flow properties of granules like bulk density, tapped density, Carr index, Hausner’s ratio, angle of repose as well as physical parameters of the compressed tablets including hardness, friability, thickness and disintegration time were determined and found to be satisfactory. The FTIR spectroscopic analysis showed that the formulation containing plant gum is compatible with the drug and other excipients used in tablets formulation. Hence the plant gum has role as a potential binder in tablets formulations. The dissolution profile showed that tablets formulations containing Prunus domestica gum 15 mg/200 mg of total weight of tablet as binder showed better results as compared to PVP K30.

Jafer, H. M. "Soft soil stabilisation using a novel blended cementitious binder produced from waste fly ashes." Thesis, Liverpool John Moores University, 2017. http://researchonline.ljmu.ac.uk/7541/.

Full text
Abstract:
Soil stabilisation is one of the most common techniques used to mitigate the undesirable properties of soft soils such as low compressive strength and high compressibility. Cement is the most commonly used binder for soil improvement applications in the UK and worldwide due to its high strength performance. However, its manufacture is energy intensive and expensive, contributing approximately 7% of global carbon dioxide (CO2) emissions. Therefore, the search for alternative raw materials, such as waste and by-products, is becoming critical in order to develop cost effective and more environmentally friendly binders to replace cement and reduce its negative environmental impact. Blended waste material fly ashes have been identified as promising alternatives to traditional binders (cement CEM-I) in different construction industries including ground improvement. The reuse of waste material fly ashes such as waste paper sludge ash (WPSA), palm oil fuel ash (POFA) and rice husk ash (RHA) has many advantages, specifically in terms of eliminating the cost of their transportation and eventual landfill, their continuous supply and the negligible, or zero, cost of production. This research project details the process of the development of a new cementitious binder, produced by blending cement-free WPSA, POFA and RHA under physico-chemical activation using flue gas desulphurisation (FGD) gypsum, for use in soft soil stabilisation. The effects of different binders produced from unary (WPSA), binary (WPSA and POFA) and ternary (WPSA, POFA and RHA) blended mixtures, along with ground and FGD gypsum activated ternary mixtures, on the geotechnical properties of soft soils, were extensively investigated. Comparisons of Atterberg limits, strength (unconfined compressive strength (UCS)), compressibility characteristics and durability (wetting-drying cycles effect) of untreated soil and soil stabilised with the optimum unary, binary, ternary and activated ternary mixtures and a reference cement treated soil, have been carried out. An investigation of the microstructural and mineralogical composition of the newly developed binder, in comparison to those of the reference cement, was also carried out using X-ray diffraction (XRD) analysis, scanning electron microscopy (SEM) imaging and energy dispersive X-ray (EDX) spectroscopy analysis. The results indicate that the soil stabilised with the ternary mixture activated by FGD gypsum (T+FGD), had the greatest compressive strength, compressibility and durability improvement; the performance of the newly developed cementitious binder was comparable to that of the reference cement. This binder comprises 8% WPSA + 2% POFA + 2% RHA activated with 5% of FGD, by the total mass of binder. The addition of FGD gypsum has been observed to enhance the pozzolanic reaction, leading to improved geotechnical properties; mainly UCS which increased over time of curing and exceeded that for the soil treated with reference cement, after 180 days. The results obtained from XRD analysis, SEM testing and EDX analysis revealed the formation of hydrated cementitious products represented by calcium silicate hydrates (C-S-H), Portlandite (CH) and ettringite. The formation of these hydrates reveals the developments gained in the geotechnical properties of the treated soil. A solid, coherent and compacted soil structure was achieved after using T+FGD, as confirmed by the formation of C-S-H, CH and ettringite. Therefore, a new, Cost effect, eco-friendly and sustainable cementitious binder has been successfully developed and can be used with confidence for soft soil stabilisation, as a 100% replacement of conventional cement.

Full text
Abstract:
Froth flotation is the most efficient method for phosphate separation, which is a physic-chemical separation process based on the difference of surface properties between the valuable minerals and unwanted gangue minerals. However, the presence of clay slimes in the slurry after grinding consumes a large amount of reagents, decreases the collision probability between bubbles and minerals, prevents phosphate particle attachment to air bubbles, and thus considerably reduces flotation recovery and concentrate grade. Georgia Pacific Chemical, LLC has recently developed novel depressants, i.e., clay binders, which are a series of low molecular weight specialty polymers to help improve phosphate flotation performance by selectively agglomerating and depressing clay particles, thus lowering their surface area and reducing the adsorption of surfactants. This thesis addresses the effects of clay binders on phosphate flotation performance and their adsorption behavior on different minerals in a sedimentary phosphate ore. Quartz Crystal Microbalance with Dissipation technique (QCM-D) was used to study adsorption characteristics of clay binders and batch flotation tests were performed under different conditions to investigate phosphate flotation performance. The experimental results have shown that clay binders significantly improved phosphate flotation selectivity and reduced the dosages of collector and sodium silicate used as dispersant in the industry.

Full text
Abstract:
The research reported herein deals with evaluation of rutting susceptibility of different asphalt binders thorough various parameters and correlating them with parameters resulted from tests carried out on their corresponding mixtures. Several factors influence the occurrence of rutting in asphalt mixtures including aggregate properties, composition (aggregate gradation and binder content), and volumetric. However Asphalt binders play a major role in affecting rutting resistance of asphalt mixtures used in road pavements. In the first phase of research four different types of asphalt binders were analyzed by subjecting them to a new protocol combining Single Creep-Recovery (SCR) tests with Multiple Stress Creep (MSC) tests on DSR. Low shear viscosity (LSV) and Multiple Stress Creep Recovery (MSCR) tests were also performed for comparison purposes. LSV and MSCR tests are currently known as standard procedure for the evaluation of rutting susceptibility of binders. However, recent studies have shown the existence of significant drawbacks for LSV and MSCR method when applied to highly modified polymers products. Three shear stress levels (20, 100 and 500 kPa) were applied in case of MSC tests. In case of SCR test 100 kPa shear stress was applied. Two neat binders having same penetration grade 50/70 but different sources were tested at four temperatures (46°C, 52°C, 58°C and 64°C). Asphalt rubber and SBS modified binder were tested at 58°C, 64°C, 70°C and 76°C. The higher range of temperature was used because the aim of testing protocol was to reach steady state flow during creep phase at all temperatures. In case of MSCR tests on AR and PMB tests were started at 64 °C and for NA and NB same temperature range selected for SCR and MSC was also applied. In case of SCR-MSC creep compliance rate from creep phase and permanent compliance from recovery phase were calculated in order to rank binders for their rutting susceptibility. In case of LSV and MSCR tests EVT (Equi-viscous temperature) and non-recoverable compliances were calculated respectively. Single creep-recovery tests combined with multiple stress creep were found to be more accurate in ranking binders for their rutting susceptibility. In the 2nd phase of research the rutting resistance of asphalt mixtures containing above mentioned binders was evaluated. In particular three dense –graded and three gap-graded rubberized mixtures were investigated. Two rubberized gap graded mixtures were prepared in laboratory, one with 2 % filler and the second one with 5 % filler. The third gap graded rubberized mixture was supplied by a plant located in the center of Italy. Amount of binders in all gap graded asphalt mixture was 8 %. The first Dense-graded asphalt mixture was prepared in laboratory with neat binder NA. The second one was collected from local plant which employed neat binder NB, having same penetration grade as the first one but different source and slightly lower maximum design temperature. The third mixture was also prepared in laboratory with SBS polymer modified binder. The binder contents in dense graded asphalt mixtures were 5.5 %. All the three mixtures were analyzed by subjecting cylindrical specimen to Flow number tests on APMT. Flow number has been recognized as newly anti-rutting indicator of asphalt mixtures. Flow numbers for all the mixtures were measured at 3 different temperatures (46°C, 52°C and 58°C). These testing temperatures were selected keeping in mind diversity of pavement temperature across the country. The 2nd purpose of selecting different testing temperature was to study how Flow number varies with change in temperature. The results obtained from mixtures were compared with those obtained from binders. Considering three binders NA, NB and SBS and their corresponding mixtures, it was observed that strong correlation exists between binder parameters and Flow number, so parameters from binder testing can be used to predict rutting susceptibility of their corresponding mixtures. Rectangular specimens were prepared from all rubberized gap graded asphalt mixtures and one traditional mixture. These specimens were tested on wheel tracking test device in order to compare results from AMPT with WTD.

Abstract:
abstract: Increased priority on the minimization of environmental impacts of conventional construction materials in recent years has motivated increased use of waste materials or bi-products such as fly ash, blast furnace slag with a view to reduce or eliminate the manufacturing/consumption of ordinary portland cement (OPC) which accounts for approximately 5-7% of global carbon dioxide emission. The current study explores, for the first time, the possibility of carbonating waste metallic iron powder to develop carbon-negative sustainable binder systems for concrete. The fundamental premise of this work is that metallic iron will react with aqueous CO2 under controlled conditions to form complex iron carbonates which have binding capabilities. The compressive and flexural strengths of the chosen iron-based binder systems increase with carbonation duration and the specimens carbonated for 4 days exhibit mechanical properties that are comparable to those of companion ordinary portland cement systems. The optimal mixture proportion and carbonation regime for this non-conventional sustainable binder is established based on the study of carbonation efficiency of a series of mixtures using thermogravimetric analysis. The pore- and micro-structural features of this novel binding material are also evaluated. The fracture response of this novel binder is evaluated using strain energy release rate and measurement of fracture process zone using digital image correlation (DIC). The iron-based binder system exhibits significantly higher strain energy release rates when compared to those of the OPC systems in both the unreinforced and glass fiber reinforced states. The iron-based binder also exhibits higher amount of area of fracture process zone due to its ability to undergo inelastic deformation facilitated by unreacted metallic iron particle inclusions in the microstructure that helps crack bridging /deflection. The intrinsic nano-mechanical properties of carbonate reaction product are explored using statistical nanoindentation technique coupled with a stochastic deconvolution algorithm. Effect of exposure to high temperature (up to 800°C) is also studied. Iron-based binder shows significantly higher residual flexural strength after exposure to high temperatures. Results of this comprehensive study establish the viability of this binder type for concrete as an environment-friendly and economical alternative to OPC.

Abstract:
Les protéines Binder of Sperm (BSP) appartiennent à une superfamille de protéines exprimées dans le système reproducteur masculin, plus particulièrement dans les vésicules séminales chez les ongulés, et dans l’épididyme chez l’humain et la souris. Jusqu'à présent, des rôles variés chez différentes espèces ont été démontrés pour les protéines BSP, tels que dans la motilité et la capacitation chez le bovin. Cependant, leur rôle demeure élusif chez d’autres mammifères comme la souris et l’humain. Des études in vivo récentes ont démontré que la délétion des gènes Bsph1 et Bsph2 chez la souris n’a aucune conséquence sur la fertilité, et n’induit aucune anomalie au niveau de l'appareil reproducteur masculin. Afin d'élucider le rôle spécifique de la protéine BSP chez l'humain (BSPH1), nous avons d’abord développé une méthode de purification efficace permettant d’obtenir la protéine BSPH1 fonctionnelle car ces protéines ne sont présentes qu'en quantité infime dans l’épididyme humain. Suite, a la purification de BSPH1, j’ai réalisé des expériences in vitro et cherché à identifier son réseau d'interaction protéique. Il a été démontré que les protéines BSP interagissent avec des groupes pseudo-choline tels que le diéthylaminométhyle par affinité plutôt que par des interactions ioniques. Le diéthylaminoéthyle est chargé positivement et par conséquence, est un échangeur d'anions faible, mais les BSP interagissent avec affinité à la résine. Cette étude présente également une nouvelle méthode de purification rapide et peu coûteuse, qui fournit des protéines BSP recombinantes de grande pureté qui peuvent être utilisées pour étudier leurs rôles dans la fécondation chez les mammifères. Nous avons montré que la pré-incubation des ovocytes avec la protéine BSPH1 recombinante peut diminuer le taux de fécondation de manière dose-dépendante. Les spermatozoïdes ont également été pré-incubés avec un anticorps anti-BSPH1 et ont montré une diminution du taux de fécondation. Pour identifier le réseau d’interaction protéique de BSPH1, j'ai utilisé la méthode « Proximity-dependent biotin identification » (BioID) couplée à la spectrométrie de masse. Les résultats de la spectrométrie de masse ont démontré une interaction entre BSPH1 et toutes les sous-unités du complexe CCT / TRIC (Chaperonin containing tailless complex polypeptide 1 (CCT) ou tailless complex polypeptide 1 ring complex (TRiC)). Ce complexe interagit avec un autre complexe appelé BBSome (Bardet–Bied syndrome complex), qui joue un rôle important dans le transport de protéines à travers les cils primaires. BSPH1 a également interagi avec un grand nombre de protéines de la famille CEP (centrosome-associated proteins), importantes dans la formation des cils primaires par les microtubules et de la maturation du centrosome, qui soutiennent le rôle de BSPH1 dans les cils primaires. Dans l’ensemble, cette étude démontre que BSPH1 pourrait avoir un nouveau rôle en tant que chaperonne, à travers les cils primaires dans les cellules qui l’expriment dans l’appareil reproducteur masculin.
Binder of SPerm (BSP) proteins belong to a superfamily of proteins expressed in the male reproductive tract, particularly in seminal vesicles of ungulates (e.g., bovine, ram) and in the epididymis of humans and mice. So far, BSP proteins have been shown to play different roles in different species such as in motility and capacitation in bovine; however, their role remains unclear in other mammals. For instance, depletion of Bsph1/Bsph2 in mice had no effect on fertility. In order to elucidate the specific role of BSP protein in humans (BSPH1), I sought to investigate a purification method to produce functional human BSP protein, as these proteins are only present in minute amounts in the human epididymis. Following purification of BSPH1, I carried out in vitro experiments and sought to identify its protein interaction network. BSP proteins have been shown to interact with pseudo-choline groups such as diethylaminomethyl through affinity rather than ionic interactions. Diethylaminoethyl is positively charged and therefore is a weak anion exchanger, but BSPs interact through affinity to this resin. This study presents a new, rapid and cost-effective purification method that provides recombinant BSP proteins of a high purity level, which can be used to study their roles in mammalian fertilization. We showed that pre-incubation of oocytes with recombinant BSPH1 can decrease fertilization rate in a dose-dependant manner. Sperm were also preincubated with anti-BSPH1 antibody and showed a decrease in fertilization rate. Secondly, I used BioID (proximity-dependent biotin identification), coupled with mass spectrometry to identify the protein-protein interaction network of BSPH1 by proximity labeling. Mass spectrometry results showed an interaction between BSPH1 and all subunits of the CCT/TRIC complex (Chaperonin containing tailless complex polypeptide 1 (CCT) or tailless complex polypeptide 1 ring complex (TRiC). This complex interacts with another complex called BBSome (Bardet–Biedl syndrome complex), which plays a role in protein trafficking through primary cilium. I also identified BBS proteins, as well as other proteins, that interact with the BBSome complex and regulate protein trafficking in the cilia. BSPH1 also interacted with a large number of CEP (centrosome-associated proteins) family proteins, important in the formation of primary cilium through microtubules and centrosome maturation, which further support the potential implication of BSPH1 with the primary cilia. Overall, this study demonstrates that BSPH1 may have a new role as a chaperone involved in protein trafficking through the primary cilia in cells that express it in the male reproductive system

This work mainly consists of four topics: (a) synthesis of novel polyimide-Cl ionic liquid by thermal cyclodehydration, (b) application of polyimide-Cl ionic liquid as a binder for Lithium–sulfur batteries, (c) polyimide-Cl ionic liquid/PAN composite binder for enhancing electrochemical stability of lithium-sulfur batteries, and (d) the interaction mechanism between binder and electrode materials by ex-situ analysis. First, a novel multifunctional binder comprising of polymeric ionic liquid, polyimide-chlorine ionic liquid complex coupled with chlorine anions is developed, prepared by a four-step recrystallization method through thermal cyclodehydration. The concept of synthetic structure was mainly by grafting ionic liquid functional groups on the side chain of polyimide, in order to lower down the temperature of glass transition point of polymer and facilitate the swinging of the side chain, thereby, increasing the ionic conductivity, PICl-IL were synthesized and confirmed by NMR and FTIR. The loading amount of sulfur was fixed around 0.96 mg/cm2, and the discharge capacity delivers as 719.8 mAh/g, which is better than electrode with the commercial binder (~540 mAh/g). In addition, PICl can also trap the lithium polysulfides and minimize the shuttle effect and sulfur loss. Next, composite binder with lipophilic compound was prepared. After optimization, the fabricated composite binder PICl-IL/PAN-10 (1:1) showed better capacity retention after 50 cycles with discharging-charging rate of 0.1 C. The composite binder showed a capacity of 801.6 mAh/g and retention of 82.8% at the 50th cycle, exceeding the retention of a commercial binder. The nitrile group on PAN backbone possess good affinity towards polysulfides Li2Sn (4≤n≤8) due to the strong dipole-dipole interactions. The addition of highly polar PAN helped disperse the conductive carbon and sulfur powder, which were poorly dispersed in PICl-IL and improved insufficient viscosity of PICL-IL, as well as increased the ionic conductivity. Therefore, PICl-IL/PAN-10 (1:1) can deliver a high reversible capacity of 339.2 mAh/g at 2 C-rate. The results show that the compound binder has a good complementary function and enhance the stability of carbon/sulfur composite. Furthermore, the synchrotron-based X-ray absorption spectroscopy (XAS) and X-ray photoelectron spectroscopy (XPS) were used to study the interaction mechanism between binder and electrode materials. It demonstrated that new PICl-IL/PAN binder can effectively reduce the reactions with the electrolyte at the first cycle, and SEI is formed on the surface of the cathode material, and decreases the loss of sulfur. In conclusion, the PICl-IL/PAN binder exhibits better chemical resistance and excellent functions, such as strong adhesion, good dispersion and high ionic conductivity. As a result, the composite binder is capable of effectively trapping polysulfides to improve the electrochemical performance of sulfur composite cathode. PICl-IL is thought to be a promising multifunctional binder for Li-S batteries.

This dissertation is divided into six parts: (a) introduction of lithium-ion batteries, and its components cathode, electrolyte and anode (chapter 1). (b) a green and facile approach for hydrothermal synthesis of LiFePO4 using iron metal directly (chapter 2). (c) (pentafluorophenyl)diphenylphosphine as a dual-functional electrolyte additive for LiNi0.5Mn1.5O4 cathodes in high-voltage lithium-ion batteries (chapter 3). (d) cross-linked polyisoprene-graft-maleic anhydride as an efficient binder for silicon anodes of lithium-ion battery (chapter 4). (e) CoO nanoparticles with superior cycle life as anode material for lithium-ion batteries (chapter 5). (f) synthesis and electrochemical performance of phase pure NaCoPO4 as a cathode for sodium-ion batteries (chapter 6). Fossil fuels, such as oil, gas, and coal are the main energy resources for transportation and electricity. However, burning of fossil fuels emits greenhouse gases, thereby causing air pollution and climate change. To mitigate these issues, environmentally friendly renewable energy, such as wind and solar energy, have been used as alternative energy sources. However, wind power and solar power are intermittent, which necessitates the need for storing renewable energy and devising an efficient storage technology. Batteries can store large amounts of energy and supply power to meet energy demands. Lithium-ion batteries (LIBs), in particular, have attracted significant attention since their commercialization in 1991. The cathode, anode, and electrolyte are the primary components of LIBs. These components must be further improved and LIB production must be made cost-effective to meet the ever increasing energy demand. The aim of this study is to explore all the three battery component materials. Chapter 1 introduces LIBs and its components. The first component in LIB is a cathode material. Among all the LIB cathode materials, LiFePO4 has received considerable attention for its excellent thermal stability, low cost, environmental friendliness, and high reversibility of Li+ ion. Moreover, the synthesis of cathode materials must be eco-friendly and cost-effective. Herein, LiFePO4 is hydrothermally synthesized using iron metal (Fe0) as the iron source. Fe0 delivers 100% atomic efficiency and acts as an in situ reducing agent, making the synthesis process eco-friendly and inexpensive. Phase evolution of LiFePO4 is studied via powder X-ray diffraction (XRD) at different temperatures, and a plausible mechanism is proposed. The XRD pattern confirms the phase purity of the calcined LiFePO4, and its discharge capacity is 165 mAh g 1 at 0.1 C-rate, with good cycle life at 0.5 C-rate. Chapter 2 discusses the results of this process. The second component in LIB is electrolyte. Electrolyte systems with >5 V electrochemical window are essential to obtain LIBs with a high energy density. Carbonate-based electrolytes undergo oxidation beyond 4.5 V vs Li/Li+. Herein, (pentafluorophenyl)diphenylphosphine (PFPDPP) is investigated as a novel, effective, and stable cathode–electrolyte interface-forming additive for LiNi0.5Mn1.5O4. The electrochemical performance of LiNi0.5Mn1.5O4 is considerably improved using a 0.2 wt% PFPDPP-containing electrolyte. After 300 cycles, the capacity retention is 71% with the additive and 53.4% without the additive. Cyclic voltammetry and theoretical density functional theory calculations reveal that PFPDPP undergoes preferential oxidation. Chapter 3 discusses the results of this approach. The third component in LIB is anode material. Graphite is the most commonly used anode material due to its excellent cycle stability. However, its low theoretical gravimetric lithiation capacity (372 mAh g 1) limits its energy supply and power density for high-end applications such as electric vehicles. Owing to its high theoretical lithiation capacity (3579 mAh g 1) and low working potential (~0.5 V vs. Li/Li+), silicon (Si) is considered a promising alternative anode material. However, the volume of Si considerably changes during the charge–discharge process, which must be addressed before utilizing its interesting electrochemical properties. Binder, a key component in the electrode structure, plays a vital role in maintaining the structural integrity of electrode components during cycling. Herein, polyisoprene-graft-maleic anhydride is explored as a novel cross-linkable binder for the Si anode of LIBs. This binder is thermally cross-linked to form an elastic material, which can relieve the stress incurred during the lithiation–delithiation process. The cross-linked material displays a high initial charge capacity of ~3300 mAh g 1 and can retain more than 60% of its capacity over 200 cycles at 0.5 C-rate. This stable cycle life can be attributed to the three-dimensional polymeric network derived from the cross-linked material. Considering the low cost of the starting materials used and the ease of preparing the binder, the proposed approach can be a viable and cost-effective solution for industrial applications. Chapter 4 discusses the results of this approach. Transition metal oxides, such as cobalt oxides, have also been extensively researched as alternative anode materials for graphite because of their higher theoretical capacities compared to graphite. Herein, a simple and scalable synthesis of Co3O4 nanosheets and CoO nanoparticles via a solvothermal method is reported. Compared with bulk materials, nanomaterials exhibit superior electrochemical performances owing to their ultrafast lithium storage property. The as-synthesized Co3O4 nanosheets form CoO nanoparticles with a particle size of ~100–200 nm when calcined at 700°C for 4 h in an N2 atmosphere. The synthesized nanomaterials are characterized via powder XRD, scanning electron microscopy (SEM), and charge–discharge cycle tests. Chapter 5 discusses the test results. Cost is a vital factor for the mass production of batteries. Because of natural abundance and low cost of sodium, sodium-ion batteries (SIBs) have gained prominence. However, finding the right cathode and anode materials for SIBs is challenging. Herein, NaCoPO4 is explored as a cathode material for SIBs, and solvothermal and hydrothermal methods are used for synthesizing phase-pure NaCoPO4. Depending on the solvent and heating time, materials with different particle sizes and shapes are obtained. The thus-obtained powders are characterized via powder XRD, SEM, and cyclic voltammetry techniques. Chapter 6 discusses the results of this work. The encouraging outcomes of this study can significantly contribute to the development of LIB component materials.

This study investigates the acoustic performance of materials made using various amounts of bio-binder (cis-1,4-polyisoprene). The filler used in making these materials was from recycled tyres which consist of nylon 6,6 fibres bonded to rubber grains known as tyre shred residue (TSR). The materials have shown high acoustical performance especially at low binder levels, due mainly to the open porosity of the tested samples. The paper begins with a discussion of materials made using recycled granulates. The macroscopic properties (e.g. flow resistivity, porosity, tortuosity, etc.) that control the acoustical behaviour of these materials are then defined as are methods for their measurements. The acoustical characterisation of porous media is considered next, followed by discussion of the acoustic performance of the materials. The characteristics of these novel materials are illustrated through experimental and theoretical models involving sound absorption and transmission.

Abstract:
Silicide based compounds are widely used for coatings due to their high melting temperature, oxidation resistance and moderate density. Employment of binders based on silicides of transitional metals can provide cBN-based cutting tools with higher chemical stability and better performance. The relationship between phase composition, microstructure and mechanical properties of novel polycrystalline cubic boron nitride (PcBN) materials were investigated. Three series of PcBN samples were made by high pressure high temperature (HPHT) sintering. Silicides of chromium – CrSi2, vanadium – VSi2 and molybdenum MoSi2 were used as a binder phase in each case, while aluminum was introduced to the mixture as an oxygen getter. During HPHT sintering at temperatures above 1850 ∘C the formation of borides of binder phase were observed in cases with VSi2 and MoSi2. For system with CrSi2 binder, temperature of boride formation was found to be lower – 1600 ∘C. Materials with MoSi2 binder phase demonstrated the highest level of microhardness. Performance of materials were investigated in conditions of machining of stainless steel AISI 316L and Inconel 718.

Abstract:
Cold recycling with cement and bituminous emulsion is one of the most environmentally friendly techniques to maximize the reuse of reclaimed asphalt (RA) collected during demolition of roads. Cold recycled mixtures are commonly used for base courses in construction or rehabilitation of flexible and semi-rigid pavements. Current experiences demonstrated that cold recycling with appropriate requirements and technical recommendations allows long-lasting pavements to be designed. Those outcomes stimulated researchers and engineers in the new challenge of using the cold recycled mixtures in binder layers that are generally more often included in maintenance planning. This paper summarizes current San Marino and Polish experiences with cold recycled mixtures designed for binder layers. The first part of the paper presents the design phase of the cold recycled mixtures in both countries. It describes and compares the composition of the mixtures, grading curves of the mineral mixtures, binding agents and requirements. The second part of the paper shows laboratory test results of mechanical properties of cold recycled mixtures for binder courses including test results in full-scale application.

Abstract:
Abstract Hardmetal-like coatings on the base of titanium carbide as a hard phase and nickel as a metal binder were prepared from agglomerated and sintered powders by plasma spray, detonation gun spray and high-velocity oxygen-fuel spray processes. The powders used in the spray experiments were plain TiC-Ni type and alloyed (Ti,Mo)C-NiCo type powders with different binder content. The coatings were characterized by optical and scanning electron microscopy, microhardness measurements, XRD analysis and in an abrasion wear test. The results showed that the sprayability of these novel hardmetal-like powders is good in all spray processes studied and the coatings deposited were found to have dense microstructures and good properties. The XRD analysis showed that the coatings have a phase structure similar to that found in the spray powder. The amount of retained carbides in the coatings was high. Some regions in which the carbides had dissolved with the metallic binder phase during spraying were also found, especially in plasma sprayed coatings. In such microstructural regions submicron size reprecipitated carbides were detected. These were clearly detectable in detonation gun sprayed coatings. HVOF sprayed coatings were found to contain a very high content of retained carbide phase. In this process the heat effect to the material seemed to be the lowest. The wear tests clearly showed the importance of alloying the hard phase and the binder phase in order to improve the wear resistance of the coatings. All studied spray processes produced coatings with nearly similar coating wear properties.

Abstract:
Abstract Objective of this study is to prepare the binder jetting feedstock powder by spray freeze drying and study the effects of its parameters on the powder properties. Binder jetting additive manufacturing is a promising technology for fabricating ceramic parts with complex or customized geometries. However, this process is limited by the relatively low density of the fabricated parts even after sintering. The main cause comes from the contradicting requirements of the particle size of the feedstock powder: a large particle size (> 5 μm) is required for a high flowability while a small particle size (< 1 μm) for a high sinterability. For the first time, a novel technology for the feedstock material preparation, called spray freeze drying, is investigated to address this contradiction. Using raw alumina nanopowder (100 nm), a full factorial design at two levels for two factors (spraying pressure and slurry feed rate) was formed to study their effects on the properties (i.e., granule size, flowability, and sinterability) of the obtained granulated powder. Results show that high pressure and small feed rate lead to small granule size. Compared with the raw powder, the flowability of the granulated powders was significantly increased, and the high sinterability was also maintained. This study proves that spray freeze granulation is a promising technology for the feedstock powder preparation of binder jetting additive manufacturing.

Abstract:
Abstract In this work, the physical phenomenon of the polydisperse micro-particle entrainment process from density mismatch mixture is investigated with the variation of substrate withdrawal speed. A liquid carrier system (LCS) is prepared by a polymer-based binder and an evaporating solvent. Nickel-based inorganic and spherical particles with a. moderate vol%. of 35% are added to the LCS solution. The cylindrical AISI 1006 mild steel wire substrate is dipped at different withdrawal speed ranging from 0.01 mms-1 to 20 mms-1. The binder vol%. is varied between 6.5% and 10.5%. Once the cylindrical substrate is extracted from the mixture, the surface coverage and the particle size are measured following the image analysis technique. The average particle size, coating thickness and the surface packing coverage by the particles are increasing with the higher withdrawal speed of the substrate. We observed relatively low size of particles (< 10 micrometers) as well as low surface coverage (∼33%) when the withdrawal speed remains at 0.01 mm/s. However, with high withdrawal speed (20 mm/s), we found all sizes of particles present on the substrate with a surface coverage of over 90%. The finding of this research will help to understand the high-volume solid transfer technique and develop a novel manufacturing process.

Abstract:
The novel lightweight repair mortar was designed and tested in respect to its resistance against salt crystallization and salinization. Natural hydraulic lime was used as the only binder, and the expanded glass granules were applied as lightweight aggregate. As reference, control mortar with silica sand aggregate was examined as well. The performed tests and analyses were aimed at the assessment of the structural, mechanical, hygric, and thermal properties of the 28-days and 90-days hardened mortars. Specific attention was paid to the evaluation of salt crystallization resistance and measurement of the effect of salt presence on the mortars� hygroscopicity, which were tested for 90-days samples only. The use of expanded glass granules in composition of natural hydraulic lime-based mortar led to its overall functional and technical improvements, i.e. high porosity, low density, sufficient mechanical strength, improved water absorption and transport, enhanced thermal insulation performance, increased hygroscopicity, and resistance against salt crystallization. Taking into account the compatibility, functional, and technical criteria, novel natural hydraulic lime-based lightweight mortar was classified as repair mortar providing enhanced thermal insulation function.

Abstract:
Research is currently ongoing for composite materials using natural fiber with a small burden on the environment. We have been focusing on bamboo because of its fast growth, renewability, flexibility, low cost, and high specific strength. We previously proposed a novel hot press fabrication method for binder-free green composite products made from bamboo fibers extracted by end-milling with a machining center. We can use this method to form three-dimensionally shaped products, especially hemispherical shells, by using two kinds of dies. However, this method is complex and takes longer than one-step hot press forming. In the present report, we propose a new method that uses bamboo powder with a particle size of less than 500 μm. Our new method uses one-step hot press forming and is quicker than the previous method at making a hemispherical shell shape. The new method was successfully used to manufacture hemispherical shell-shape products.

Abstract:
This Dredging Operations Environmental Research (DOER) technical note disseminates novel methods to monitor and reduce contaminant mobility and bioavailability in water, sediments, and soils. These method advancements are enabled by additive manufacturing (i.e., three-dimensional [3D] printing) to deploy and retrieve materials that adsorb contaminants that are traditionally applied as unbound powders. Examples of sorbents added as amendments for remediation of contaminated sediments include activated carbon, biochar, biopolymers, zeolite, and sand caps. Figure 1 provides examples of sorbent and photocatalytic particles successfully compounded and 3D printed using polylactic acid as a binder. Additional adsorptive materials may be applicable and photocatalytic materials (Friedmann et al. 2019) may be applied to degrade contaminants of concern into less hazardous forms. This technical note further describes opportunities for U.S. Army Corps of Engineers (USACE) project managers and the water and sediment resource management community to apply 3D printing of polymers containing adsorptive filler materials as a prototyping tool and as an on-site, on-demand manufacturing capability to remediate and monitor contaminants in the environment. This research was funded by DOER project 19-13, titled “3D Printed Design for Remediation and Monitoring of Dredged Material.”
