Abstract:
A UV curable coating modified by several inorganic particles was prepared and characterized. Several kinds of inorganic particles including glass powder, mica, alumina, talcum powder and polyimide were introduced to epoxy acrylate (EA) as fillers and mixed with reactive diluent, photoinitiators, and other additives to obtain an organic-inorganic ultraviolet (UV) curable coating. Different kinds of inorganic powders were mixed in proportion to the formula and ground in a ball mill for 16 h to obtain smaller particles. The particle size and morphology of inorganic powders were characterized by laser particle size analyzer and scanning electron microscopy (SEM). The results indicated that the particle size of inorganic powders was reduced effectively after ball-milled. The morphology of the synthesized UV curable organic-inorganic composite coating was observed, and the mechanical and thermal properties of the coating were tested. Pure organic EA coating without the addition of inorganic particles was also characterized as controls. The distribution of inorganic particles in the coating was homogeneous and the surface of the cured coating was smooth. The results of mechanical properties tests showed that the addition of inorganic particles improved the hardness of the coating, but the effect on adhesion and flexibility was not significant. And the TGA curves showed that the thermal stability of the coating modified by inorganic particles was significantly improved compared with the pure organic coating.

Abstract:
Inorganic nanocarriers for a decade have increased interest in nanotechnology research platform as versatile drug delivery materials. The utility of the inorganic nanocarriers for delivery of therapeutic agents is attributed to their unique properties such as magnetic, photocatalytic nature and the ability to exhibit surface functionalization. Herein, we review the surface functionalization and delivery utility for natural therapeutics exhibited by inorganic nanocarriers mostly focusing on their magnetic, photocatalytic and the plasmonic properties. The review also highlights the influence of electronic property of inorganic surface on functionalization of ligand based natural therapeutic agents. Improvement of stability and therapeutic potential by formation of nanocomposites are detailed. Furthermore, we suggest improvement strategies for stability and toxicity reduction of inorganic nanoparticles that would potentially make them useful for clinical application as therapeutic delivery tools for treatment of various diseases.

Abstract:
The synthesis of reduced graphene oxide was carried out using the smoke catcher method and inorganic waste. The inorganic waste smoke obtained became the basic material as a carbon source. After burning the inorganic waste, the smoke collected was in the form of a powder and exposed to microwaves. Based on FTIR characterization, the synthesis was successfully carried out by obtaining ~ 1600 cm-1 as the peak of the aromatic functional group (C = C) or graphene functional group. After the inorganic waste smoke sample was put in the microwave, the rGO sample was obtained which had a higher crystallinity than before heating in the microwave.

Woolley, Martin Fraser. "The synthesis and polymerisation of some conjugatively extended p-xylylenes." Thesis, Durham University, 1991. http://etheses.dur.ac.uk/5985/.

Full text
Abstract:
This thesis describes studies directed towards the preparation of new conjugatively extended p-xylylenes through in situ 1,6- or 1,8-Hoffmann elimination reactions of trimethylammonium salts. The polymers arising from these highly reactive compounds were analysed in order to determine whether or not the extra conjugation had been involved in the polymerisation process. A number of fascinating by-products were also isolated which were useful in determining the structural unit orientation in the related polymer chains. Chapter 1 highlights the areas of p-xylylene chemistry of relevance to the general theme of this thesis. Chapter 2 describes the in situ synthesis and consequent polymerisation of vinyl-extended p-xylylene from two different trimethylammonium salts. An in-depth analysis of the polymers and the two cyclic dimers produced is also included. Chapter 3 describes the in situ synthesis and polymerisation of phenyl-extended p-xylylene from two different trimethylammonium salts. Once again, an analysis of die polymer structures and the identification of the two cyclic trimers is also included. Chapter 4 describes attempts to extend the polymerisation reactions of Chapters' 2 and 3 to produce water-soluble precursor polymers from bis-sulphonium salts. Chapter 5 describes attempts to synthesise novel polymeric materials from fluorinated monomers. Chapter 6 gives experimental details for Chapters 2-5.

Full text
Abstract:
In Section (I), the origins and nature of the correlation problem are discussed, and two approaches to its solution are outlined. Some of the methods by which correlation effects in the ground state of helium have been analysed in the past are briefly reviewed. In Section (II.1), position-space correlation effects in the 21S, 23S, 21P and 23P states of helium are studied. The investigation is performed by examining the effects of correlation on various radial, angular and interparticle distribution functions and expectation values; where possible, comparisons are made with the ground state. For each of the four excited states studied, it was found that correlation causes a significant inward movement of electron density from the outer regions of the atom, due to a reduction in nuclear shielding. In the light of the results obtained in position space, a3 parallel momentum-space investigation of the 23S, 21P and 23P states was performed, and the results are presented in Section (II.2). Differences between the interparticle correlation properties of the three states were rationalised by considering the varying interactions between the radial and angular components of correlation in each instance. For 23S and 21P, as for the ground state, radial and angular correlation have opposing effects on the interparticle momentum distributions; for 23P, on the other hand, the two effects act together. In Section (III), a partitioning technique used previously to examine correlation effects in individual electron pairs within many-electron atoms is applied to a momentum-space study of the (1s2 2s)2S and (1s2 2p)2P states of lithium. For both states, the effects of correlation observed in the K-shell electron pairs show a strong resemblance to those found in Li+. As for the excited states of helium, the rationalisation of the behaviour of, and differences between, the interparticle correlation properties of the intershell electron pairs was achieved by considering the varying interactions between the radial and angular components of correlation in each instance.

In this thesis, using mainly Aerosol Assited Chemical Vapor Deposition, AACVD, as a synthesis methodology for nanostructured tungsten oxide, different gas sensors have been manufactured. To study the improvement in the selectivity and sensitivity of gas sensors based on tungsten oxide, they have been decorated, via AACVD, with nanoparticles of other metal oxides to create heterojunctions to obtain an increase in electronic sensitivity, in the chemical properties of the material or at the same time in both. Particularly, we have worked on different tungsten oxide nanowire sensors decorated with nanoparticles of nickel oxide, cobalt oxide and iridium oxide resulting in sensors with a large increase in response and selectivity towards hydrogen sulfide, for ammonia. and for nitrogen oxide respectively at trace concentrations. In addition, the reaction mechanisms that take place between oxygen species adsorbed on the sensor surface when it interacts with a gas have been also studied. Furthermore, efforts have been put on trying to control the surface potential of the nanostructured layers to control the drift in the signal over time, when operating the sensors, through temperature control.

Abstract:
This thesis reports the synthesis and analysis of a number of organometallic compounds, focusing primarily on novel structures containing Sn and P atoms. Chapter 1 contains a literature review examining the different structural and bonding properties and reactions of C4H4, P4 and P2C2R2. Chapter2 describes the ability of the P2C2tBu2 ligand to cause a reductive elimination in Sn(IV) species. Several different products from the reaction between Me2SnCl2 and Cp2Zr(P2C2tBu2) are determined, and mechanisms for their interconversion are proposed. The synthesis of Sn(P2C2Ad2) is reported along with its unprecedentedly low frequency 119Sn NMR spectroscopic chemical shift. Chapter 3 contains attempts to produce transition metal complexes with phosphaalkyne based ligands. The crystal structure of a complex containing Fe and Zr centres with two P2C2Ad2 rings is reported along with analysis of its paramagnetism. Mechanisms for the exchange of P2C2R2 rings and chlorides are also proposed. Chapter 4 details the synthesis of a range of CpnSnIm species and a comparison of their solid and solution state structures using X-ray diffraction and NMR spectroscopy. Reactions between these compounds and P(SiMe3)3 or LiP(SiMe3)2 are performed in order to explore the possibility of forming a Sn-P multiple bond. Chapter 5 outlines the synthesis of bicyclic systems based on C6H4-1,2-(PH2)2 and Sn and Ge dialkyls. The effect of alkyl group bulk on product structure is investigated. Chapter 6 explores the reaction between C6H4-1,2-(PH2)2 and P(SiMe3)3 in which an exchange of H and SiMe3 groups occurs. The mechanism of the reaction is elucidated by the introduction of a catalytic proton source.

Full text
Abstract:
Future energy systems based on hydrogen as energy carrier require reliable ways for storing hydrogen gas in safe, clean and efficient ways. Metal hydrides absorb hydrogen gas reversibly, making them suitable for storage applications. Investigations of the crystal structures of these materials contribute to an understanding of the factors which can influence the absorption. Three systems, Ti3Sn-D, Nb4MSi-D (M=Co or Ni) and Pd-Ni-P, have been investigated in this thesis. Various solid state synthesis techniques have been used for sample preparation. The crystal structures have been studied using x-ray and neutron diffraction techniques. Three metal hydride phases were found in the Ti3Sn-D system upon hydrogenation. Deuterium occupies titanium octahedra and the applied deuterium pressure induces the phase transitions. The distances between the deuterium atoms increase from 2.47 Å in orthorhombic Ti3SnD0.80 to 4.17 Å in cubic Ti3SnD. The Nb4MSi-D system (M=Co or Ni) readily absorbs deuterium at room temperature and 90 kPa deuterium pressure to give a deuterium content of Nb4MSiD~2.5. Two interstitial voids, both coordinated by four niobium atoms arranged in a tetrahedral configuration, accommodate deuterium atoms. Two ternary phases and a solid solution of nickel in Pd3P have been synthesised and the crystal structures determined. PdNi2P is orthorhombic and crystallises in the MgCuAl2-type structure: an ordered derivative of the Re3B-type structure. Pd8Ni31P16 is a tetragonal high-temperature phase stable at 700°C with 110 atoms in the unit cell. Pd2.7Ni0.3P0.94 has the cementite-type structure with mixed occupancy of palladium and nickel at one of the two non-equivalent crystallographic metal positions.

Abstract:

The purpose of this thesis work is to design and fabricates organic-inorganic hetero junction White Light Emitting Diode (WLED). In this WLED, inorganic material is n- type ZnO and organic material is p-type conjugated polymer. The first task was to synthesise vertically aligned ZnO nano-rods on glass as well as on plastic substrates using aqueous chemical growth method at a low temperature. The second task was to find out the proper p- type organic material that gives cheap and high efficient WLED operation. The proposed polymer shouldn’t create a high barrier potential across the interface and also it should block electrons entering into the polymer. To optimize the efficiency of WLED; charge injection, charge transport and charge recombination must be considered. The hetero junction organic-inorganic structures have to be engineered very carefully in order to obtain the desired light emission. The layered structure is composed of p-polymer/n-ZnO and the recombination has been desired to occur at the ZnO layer in order to obtain white light emission. Electrical characterization of the devices was carried out to test the rectifying properties of the hetero junction diodes.

Abstract:
Direct Methanol Fuel Cells (DMFCs) offer advantages from quick refills to the elimination of recharge times. They show the most potential in efficient chemical to electrical energy conversion, but currently one major source of inefficiency within the DMFC system is the electrolyte allowing fuel to cross over from the anode to cathode. Proprietary DuPont™ Nafion® 117 has been the standard polymer electrolyte thus far for all meso-scale direct methanol power conversion systems, and its shortcomings consist primarily of slow anodic reaction rates and fuel crossover resulting in lower voltage generation or mixed potential. Porous Silicon (P-Si) is traditionally used in photovoltaic and photoluminescence applications but rarely used as a mechanical filter or membrane. This research deals with investigations into using P-Si as a functioning electrolyte to transfer ions from the anode to cathode of a DMFC and the consequences of stacking multiple layers of anodes. Porous silicon was fabricated in a standard Teflon cylindrical cell by an anodization process which varied the current density to etch and electro-polish the silicon membrane. The result was a porous silicon membrane with approximately 1.5 μm pore sizes when optically characterized by a scanning electron microscope. The porous membranes were then coated in approximately 0.2 mg/cm2 Pt-Ru catalyst with a 10% Nafion® solution binding agent onto the anode. Voltage versus current data shows an open circuit voltage (OCV) of 0.25V was achieved with one layer when operating at 20°C. When adding a second porous silicon layer, the OCV was raised to approximately 0.32V under the same conditions. The experimental data suggested that the current collected also increased with an additional identical layer of anode prepared the same way. The single difference was that the air cathode side was surface treated with 0.1 mg of Pt black catalyst combined with a 10% Nafion® binding agent to aid in the recombination of hydrogen atoms to form the water byproduct. Porous silicon endurance runs with 2ml of 3% by volume methanol (0.7425M) fuel dissolved in water showed an operating voltage was generated for approximately 3 hours before the level dropped to approximately 65% of the 0.25V maximum voltage. Endurance runs with a second layer added extended the useful cell life to approximately 5 hours under the same conditions. In an effort to quantify these layering results, Fourier Transform Infrared Spectrometry was conducted on a number of samples to verify decreased methanol concentration present in the second layer.

Abstract:
Objectives: 1) develop a thorough understanding of the sorption mechanisms of Pi and Po onto the Al/O- WTR; 2) determine the breakthrough range of the composite Al/O-WTR during P capturing from agro- wastewaters; and 3) critically evaluate the performance of the composite Al/O-WTR as a fertilizer using selected plants grown in lysimeters and test-field studies. Instead of lysimeters we used pots (Israel) and one- liter cone-tainers (USA). We conducted one field study but in spite of major pretreatments the soils still exhibited high enough P from previous experiments so no differences between control and P additions were noticeable. Due to time constrains the field study was discontinued. Background: Phosphorous, a non-renewable resource, has been applied extensively in fields to increase crop yield, yet consequently has increased the potential of waterway eutrophication. Our proposal impetus is the need to develop an innovative method of P capturing, recycling and reuse that will sustain agricultural productivity while concurrently reducing the level of P discharge from and to agricultural settings. Major Conclusions & Achievements: An innovative approach was developed for P removal from soil leachate, dairy wastewater (Israel), and swine effluents (USA) using Al-based water treatment residuals (Al- WTR) to create an organic-Al-WTR composite (Al/O-WTR), potentially capable of serving as a P fertilizer source. The Al-WTR removed 95% inorganic-P, 80% to 99.9% organic P, and over 60% dissolved organic carbon from the agro-industrial waste streams. Organic C accumulation on particles surfaces possibly enhanced weak P bonding and facilitated P desorption. Analysis by scanning electron microscope (SEM- EDS), indicated that P was sparsely sorbed on both calcic and Al (hydr)oxide surfaces. Sorption of P onto WW-Al/O-WTR was reversible due to weak Ca-P and Al-P bonds induced by the slight alkaline nature and in the presence of organic moieties. Synchrotron-based microfocused X-ray fluorescence (micro-XRF) spectrometry, bulk P K-edge X-ray absorption near edge structure spectroscopy (XANES), and P K-edge micro-XANES spectroscopy indicated that adsorption was the primary P retention mechanism in the Al- WTR materials. However, distinct apatite- or octocalciumphosphatelike P grains were also observed. Synchrotron micro-XRF mapping further suggested that exposure of the aggregate exteriors to wastewater caused P to diffuse into the porous Al-WTR aggregates. Organic P species were not explicitly identified via P K-edge XANES despite high organic matter content, suggesting that organic P may have been predominantly associated with mineral surfaces. In screen houses experiments (Israel) we showed that the highest additions of Al/O-WTR (5 and 7 g kg⁻¹) produced the highest lettuce (Lactuca sativa L. var. longifolial) yield. Lettuce yield and P concentration were similar across treatments, indicating that Al/O- WTR can provide sufficient P to perform similarly to common fertilizers. A greenhouse study (USA) was utilized to compare increasing rates of swine wastewater derived Al/O-WTR and inorganic P fertilizer (both applied at 33.6, 67.3, and 134.5 kg P₂O₅ ha⁻¹) to supply plant-available P to spring wheat (TriticumaestivumL.) in either sandy loam or sandy clay loam soil. Spring wheat straw and grain P uptake were comparable across all treatments in the sandy loam, while Al/O-WTR application to the sandy clay loam reduced straw and grain P uptake. The Al/O-WTR did not affect soil organic P concentrations, but did increase phosphatase activity in both soils; this suggests that Al/O-WTR application stimulated microorganisms and enhance the extent to which microbial communities can mineralize Al/O-WTR-bound organic P. Implications: Overall, results suggest that creating a new P fertilizer from Al-WTR and agro-industrial waste sources may be a feasible alternative to mining inorganic P fertilizer sources, while protecting the environment from unnecessary waste disposal.

Abstract:
Beneficial use of reclaimed wastewater (RW) and biosolids (BS) in soils is accompanied by large input of sewage-originated P. Prolonged application may result in P accumulation up to levelsBeneficial use of reclaimed wastewater (RW) and biosolids (BS) in soils is accompanied by large input of sewage-originated P. Prolonged application may result in P accumulation up to levels that impair plant nutrition, increase P loss, and promote eutrophication in downstream waters. This study aims to shed light on the RW- and BS-P forms in soils and to follow the processes that determine P reactivity, solubility, availability, and loss in RW and BS treated soils. The Technion group used sequential P extraction combined with measuring stable oxygen isotopic composition in phosphate (δ18OP) and with 31P-NMR studies to probe P speciation and transformations in soils irrigated with RW or fresh water (FW). The application of the δ18OP method to probe inorganic P (Pi) speciation and transformations in soils was developed through collaboration between the Technion and the UCSC groups. The method was used to trace Pi in water-, NaHCO3-, NaOH-, and HCl- P fractions in a calcareous clay soil (Acre, Israel) irrigated with RW or FW. The δ18OP signature changes during a month of incubation indicated biogeochemical processes. The water soluble Pi (WSPi) was affected by enzymatic activity yielding isotopic equilibrium with the water molecules in the soil solution. Further it interacted rapidly with the NaHCO3-Pi. The more stable Pi pools also exhibited isotopic alterations in the first two weeks after P application, likely related to microbial activity. Isotopic depletion which could result from organic P (PO) mineralization was followed by enrichment which may result from biologic discrimination in the uptake. Similar transformations were observed in both soils although transformations related to biological activity were more pronounced in the soil treated with RW. Specific P compounds were identified by the Technion group, using solution-state 31P-NMR in wastewater and in soil P extracts from Acre soils irrigated by RW and FW. Few identified PO compounds (e.g., D-glucose-6-phosphate) indicated coupled transformations of P and C in the wastewater. The RW soil retained higher P content, mainly in the labile fractions, but lower labile PO, than the FW soil; this and the fact that P species in the various soil extracts of the RW soil appear independent of P species in the RW are attributed to enhanced biological activity and P recycling in the RW soil. Consistent with that, both soils retained very similar P species in the soil pools. The HUJ group tested P stabilization to maximize the environmental safe application rates and the agronomic beneficial use of BS. Sequential P extraction indicated that the most reactive BS-P forms: WSP, membrane-P, and NaHCO3-P, were effectively stabilized by ferrous sulfate (FeSul), calcium oxide (CaO), or aluminum sulfate (alum). After applying the stabilized BS, or fresh BS (FBS), FBS compost (BSC), or P fertilizer (KH2PO4) to an alluvial soil, P availability was probed during 100 days of incubation. A plant-based bioassay indicated that P availability followed the order KH2PO4 >> alum-BS > BSC ≥ FBS > CaO-BS >> FeSul-BS. The WSPi concentration in soil increased following FBS or BSC application, and P mineralization further increased it during incubation. In contrast, the chemically stabilized BS reduced WSPi concentrations relative to the untreated soil. It was concluded that the chemically stabilized BS effectively controlled WSPi in the soil while still supplying P to support plant growth. Using the sequential extraction procedure the persistence of P availability in BS treated soils was shown to be of a long-term nature. 15 years after the last BS application to MN soils that were annually amended for 20 years by heavy rates of BS, about 25% of the added BS-P was found in the labile fractions. The UMN group further probed soil-P speciation in these soils by bulk and micro X-ray absorption near edge structure (XANES). This newly developed method was shown to be a powerful tool for P speciation in soils. In a control soil (no BS added), 54% of the total P was PO and it was mostly identified as phytic acid; 15% was identified as brushite and 26% as strengite. A corn crop BS amended soil included mostly P-Fe-peat complex, variscite and Al-P-peat complex but no Ca-P while in a BS-grass soil octacalcium phosphate was identified and o-phosphorylethanolamine or phytic acid was shown to dominate the PO fraction that impair plant nutrition, increase P loss, and promote eutrophication in downstream waters.
