Abstract:
Magneto-responsive textiles have emerged lately as an important carrier in various fields, including biomedical engineering. To date, most research has been performed on single magnetic fibers and focused mainly on the physical characterization of magnetic textiles. Herein, from simple woven and non-woven textiles we engineered materials with magnetic properties that can become potential candidates for a smart magnetic platform for heating treatments. Experiments were performed on tissue-mimicking materials to test the textiles’ heating efficiency in the site of interest. When the heat was induced with magneto-responsive textiles, the temperature increase in tissue-mimicking phantoms depended on several factors, such as the type of basic textile material, the concentration of magnetic nanoparticles deposited on the textile’s surface, and the number of layers covering the phantom. The values of temperature elevation, achieved with the use of magnetic textiles, are sufficient for potential application in magnetic hyperthermia therapies and as heating patches or bandages.

Abstract:
Since prehistoric times, textiles have served an important role–providing necessary protection and comfort. Recently, the rise of electronic textiles (e-textiles) as part of the larger efforts to develop smart textiles, has paved the way for enhancing textile functionalities including sensing, energy harvesting, and active heating and cooling. Recent attention has focused on the integration of thermoelectric (TE) functionalities into textiles—making fabrics capable of either converting body heating into electricity (Seebeck effect) or conversely using electricity to provide next-to-skin heating/cooling (Peltier effect). Various TE materials have been explored, classified broadly into (i) inorganic, (ii) organic, and (iii) hybrid organic-inorganic. TE figure-of-merit (ZT) is commonly used to correlate Seebeck coefficient, electrical and thermal conductivity. For textiles, it is important to think of appropriate materials not just in terms of ZT, but also whether they are flexible, conformable, and easily processable. Commercial TEs usually compromise rigid, sometimes toxic, inorganic materials such as bismuth and lead. For textiles, organic and hybrid TE materials are more appropriate. Carbon-based TE materials have been especially attractive since graphene and carbon nanotubes have excellent transport properties with easy modifications to create TE materials with high ZT and textile compatibility. This review focuses on flexible TE materials and their integration into textiles.

Abstract:
The focus of this study is to analyze heating and insulating properties of textiles utilized in the construction industry. Research regarding textile heating composites typically centers around their use in the fashion industry and personal thermal comfort. Therefore, the study focuses on the application of textile heating composites as a method for improving the local thermal comfort of the user. The aim of this project was to analyze and describe the heating and insulating properties of electroconductive yarns and insulating textiles used in the construction industry. This goal was achieved by building physical samples that underwent heating tests. The next step was to compare the examined properties and select the best combination of yarn and fabric, which was then tested in the target environment. It was concluded that the best heating results are achieved with steel thread embroidered on fiberglass mesh and combined with extruded polystyrene that can be used to improve the local thermal comfort of the user.

Abstract:
PurposeThe need for sensors and actuators is an important issue in the field of smart textiles and garments. Important developments in sensing and heating textile elements consist in using non‐metallic yarns, for instance carbon containing fibres, directly in the textile fabric. Another solution is to use electro‐conductive materials based on conductive polymer composites (CPCs) containing carbon or metallic particles. The purpose of this paper is to describe research based on the use of a carbon black polymer composite to design two electro‐conductive elements: a strain sensor and a textile heating element.Design/methodology/approachThe composite is applied as a coating consisting of a solvent, a thermoplastic elastomer, and conductive carbon black nanoparticles. In both applications, the integration of the electrical wires for the voltage supply or signal recording is as discreet as possible.FindingsThe CPC materials constitute a well‐adapted solution for textile structures: they are very flexible, and thus do not modify the mechanical characteristics and general properties of the textile structure.Research limitations/implicationsIn the case of the heating element, the use of metallic yarns as electrodes makes the final structure a more rigid. This can be improved by choosing other conducting yarns that are more flexible, or by developing knitted structures instead of woven fabrics.Practical implicationsThe CPC provide a low cost solution, and the elements are usually designed so as to work with a low voltage supply.Originality/valueThe CPC has been prepared with a solvent process which is especially adapted to flexible materials like textiles. This is original in comparison to the conventional melt‐mixing process usually found in literature.

Abstract:
Thermochromic colorants have been developed since before the 1900s. There are a large number of patents in different applications of thermochromic textiles, but many innovations leave the field of aesthetic and functional textile design unexplored in the area of smart materials. This study aims to develop thermochromic home textiles that change colors and patterns by integrating thermochromic pigments and electric conductive yarns into textile structures. Stainless steel conductive yarns were sewed on textile substrates to enable heat generation to increase fabric temperature. The heat generation and temperature rise could be controlled by monitoring the voltage applied. The experiments of this study focused on analyzing electric resistance and heating properties of the conductive yarns and observing color changing time and color changing effects of the thermochromic textiles. By using the technique in this research, an image of “tai chi” was designed and implemented in a backlighting thermochromic fabric. It illustrates a range of opportunities for thermochromic textiles in new design research directions of Chinese calligraphy and traditional Chinese painting.

Abstract:
Textiles are often used to protect people from cold environments. While most garments are designed for temperatures not far below 0 °C, very cold regions on the earth near the poles or on mountains necessitate special clothing. The same is true for homeless people who have few possibilities to warm up or workers in cooling chambers and other cold environments. Passive insulating clothing, however, can only retain body heat. Active heating, on the other hand, necessitates energy, e.g., by batteries, which are usually relatively heavy and have to be recharged regularly. This review gives an overview of energy-self-sufficient textile solutions for cold environments, including energy harvesting by textile-based or textile-integrated solar cells; piezoelectric sensors in shoes and other possibilities; energy storage in supercapacitors or batteries; and heating by electric energy or phase-change materials.

Abstract:
Purpose The purpose of this study is to investigate the utility of carbon black containing coating formulations that are conventionally used for pigment printing of textiles in fabricating electrically heated fabrics. Design/methodology/approach Specifically, electrical and thermal characterisation of the coating system was carried out to establish the feasibility of the system for use in the manufacturing of flexible heating elements on textile substrates. The coating formulations were applied via a simple padding technique followed by stitching the electrodes using a conductive yarn. Findings The heating elements of different sizes thus produced showed Ohmic behaviour as a resistor and attained a targeted temperature difference of up to 40°C within the applied voltage range. A prototype heater was also produced, and thermography results showed uniform heating and cooling of the heater that was incorporated into a jacket. Originality/value The proposed method is envisaged to be very practical for the realisation of completely textile-based heating elements of different shapes and sizes. Furthermore, the proposed manufacturing method can be used to convert conventional ready-made articles of clothing into heated textiles for various applications.

Abstract:
The textile industry accounts for approximately 2% of global greenhouse gas emissions. There is a significant opportunity to decarbonize the textile industry by electrification of process heating where low- or zero-carbon electricity is used. Electrified process heating can be achieved through cross-cutting technologies without modifying the textile process equipment and/or through replacing the existing equipment with technologies that employ electromagnetic or resistance heating techniques for specific end-use applications. This paper aims to investigate the potential for electrification of process heating in the textile wet-processing industry in three of the top textile-producing and exporting regions in the world. To do this, two separate technology pathways, i.e., electrification through (a) industrial heat pumps and (b) textile end-use processes are developed and analyzed. The results show that the total potential final energy and CO2 savings due to electrification in both scenarios could be substantially large due to the lower energy intensity of the electrified heating systems. Moreover, the costs per unit of textile production are found to be lower in the case of industrial heat pumps compared to other systems. It is concluded that wide-scale electrification of process heating in the textile wet-processing industry will require major changes to the electricity system and individual sites, and the coordination efforts among different stakeholders to plan these changes must be intensified.

Abstract:
The Joule heating of carbon fiber-based textiles enables an energy- and cost-efficient processing of carbon fiber reinforced thermoplastic parts. This article introduces a new method to pass direct current into a dry, not pre-consolidated hybrid yarn textile based on recycled carbon fibers and polyamide 6 fibers. The aim is to melt polyamide fibers, subsequently impregnate carbon fibers, and finally consolidate the material to form a composite part in a single process step. To increase the reliability of this technology, the electrical properties and the behavior of the material during the heating process must be thoroughly investigated. It will be addressed how the material is characterized during the process and how the changing resistivity of the textile affects the current flow between the electrodes to generate intrinsic heat. Moreover, a method to determine the effective material resistivity by finite element simulation on the fiber scale based on a CT scan is presented. Thus, a validated material model with respect to the temperature development in the textile based on ρ = ρ (Τ) was established.

Abstract:
In this study, the application of carbon filament yarn (CFY)-based conductive hybrid yarn as the heating element in a textile-reinforced concrete structure is reported. For this purpose, a hybrid yarn having a core-sheath structure (the core is made of carbon filament yarn and the sheath consists of a mixture of short glass and polypropylene fibres) is manufactured by DREF-2000 spinning technique and integrated into textile structure by tailored fibre placement method. Heat can be generated in the concrete structure by passing electric current through the conductive carbon filament yarn core of the hybrid yarn using the principle of resistive heating, where the sheath acts as the protection and isolation layer. From the initial investigations made on a small concrete specimen, important information is gathered and a large concrete slab with integrated conductive hybrid yarn is manufactured. The heat ability and the comfort level of the manufactured concrete slab are measured. The investigations have revealed the potential of using such hybrid yarn for a pointwise heating of the concrete surface for possible appliance in outdoor furniture.

Abstract:
Ce projet de recherche de doctorant concerne l’élaboration et l’utilisation de matériaux multifonctionnels imprimable, en mettant l’accent sur les compromis entre propriétés matériaux et spécification applicative, avec un focus autour des fonctions de chauffage par effet joule et d’électroluminescence. L’originalité des travaux repose sur une approche couplée entre matériaux multifonctionnels et intégration textile. Le premier point de l’étude concerne la sélection des matériaux multifonctionnels jugés comme potentiellement intéressants pour la création de textiles intelligents adaptés aux secteurs cibles de la société TESCA-groupe. Cette sélection impliquait la caractérisation des propriétés électriques et thermiques des matériaux conducteurs ainsi que du substrat textile. De plus, des analyses à l'aide d'appareils de microscopie électronique à balayage (MEB)/ spectroscopie à dispersion d'énergie (EDS) et diffraction de rayon X (DRX) étaient effectuées pour étudier la microstructure, notamment l'adhérence, l'épaisseur des couches déposées et la composition chimique des matériaux. Le second aspect met l’accent sur une étude du vieillissement accéléré sur des éprouvettes unitaires des substrats textiles revêtus d'encre conductrice, en conformité avec les spécifications requises de la société Tesca. L'objectif de cette démarche était d'identifier les limites inhérentes à chaque matériau, telles que la déformation maximale, les variations de température, l'adhérence, la compatibilité des processus, etc., dans le but de proposer des axes d'optimisation ou de tenir compte de ces limitations lors de la conception des transducteurs intégrés sur substrat textile. Cette première étape nous permettait d'établir une base de matériaux multifonctionnels pouvant être utilisés pour des applications spécifiques, telles que les nappes chauffantes, les interrupteurs capacitifs ou résistifs, les transducteurs, les capteurs de grandeurs mécaniques, entre autres. Le troisième volet de cette recherche consistait à assembler ces éléments de base pour créer des sous-fonctions qualifiées d’intelligente. En effet, la réalisation de transducteurs impliquait généralement la combinaison de différents matériaux multifonctionnels afin de répondre aux exigences spécifiques de l'application visée
This PhD student research project concerns the development and use of printable multifunctional materials, focusing on the trade-offs between material properties and application specification, with a particular emphasis on joule heating and electroluminescence functions. The originality of the work lies in a coupled approach between multifunctional materials and textile integration. The first part of the study concerned the selection of multifunctional materials deemed potentially interesting for the creation of intelligent textiles adapted to TESCA-groupe's target sectors. This involved characterizing the electrical and thermal properties of both the conductive materials and the textile substrate. In addition, analyses using scanning electron microscopy (SEM)/energy dispersive spectroscopy (EDS) and X-ray diffraction (XRD) were carried out to study the microstructure, including adhesion, the thickness of the deposited layers and the chemical composition of the materials. The second aspect focused on an accelerated ageing study on unit specimens of textile substrates coated with conductive ink, in compliance with the specifications required by Tesca. The aim of this approach was to identify the inherent limitations of each material, such as maximum deformation, temperature variations, adhesion, process compatibility, etc., with a view to proposing areas for optimization or taking these limitations into account when designing transducers integrated on textile substrates. This first step enabled us to establish a base of multifunctional materials that could be used for specific applications, such as heating mats, capacitive or resistive switches, transducers, sensors for mechanical quantities, among others. The third aspect of this research consisted in assembling these basic elements to create sub-functions described as "intelligent". In fact, the production of transducers generally involved combining different multifunctional materials to meet the specific requirements of the target application

Abstract:
The amount and type of antioxidants present in raspberries is dependent upon cultivar, ripeness, and growing conditions. Previous research on raspberry jam has reported some color, antioxidant, and flavor loss after processing and storage, though it is unknown to what extent similar changes will occur in raspberries grown in Utah. Sugar concentration and heating temperature as well as storage time were evaluated in an effort to maximize color retention, flavor, antioxidant content, shelf life, and consumer acceptance of Utah-grown raspberry jam. Four types of jams were processed in two batches each: low-sugar (40-42 Brix) and typical sugar (65-68 Brix) at 85 and 95 C, from two separate farms in Utah. Oxygen Radical Absorbance Capacity (ORAC), total anthocyanin content (TAC), color, headspace, Brix, pH, consistency, and water activity were measured in fresh jam, and after one and three months of typical storage (dark, room temperature) to evaluate changes after storage. A sensory analysis compared three-month stored jam to fresh jam made from the same berry crop. ORAC significantly declined in all jams during storage. Fresh low-sugar jam was found to contain higher ORAC values than high-sugar jam after processing and after three months of storage. All jams retained their initial anthocyanins over the first month and significantly lost an average of 28.8% anthocyanins between months 1 and 3 of storage. Color loss was found to be less pronounced than anthocyanin degradation, though nearly all jams maintained initial L*, C*, and h* values over the first month then significantly decreased by the third month of storage. When comparing fresh and three-month jam, significant sensory differences were found in color, overall acceptability, flavor, and texture. All parameters scored higher for freshly-made jam, though three-month stored jam was still found to be acceptable to consumers. In summary, after three months of storage, significant nutrient quantity and sensory quality remains in Utah raspberry jam, despite significant declines in several assays and significant differences between treatments.

ENGLISH ABSTRACT: Previous work has shown that microwave heating of mineral ores induces fractures around grain boundaries due to the differences in absorption of microwaves and the resulting differential thermal expansion among the various mineral phases in the ore particles. As a consequence, this reduces the energy required in subsequent grinding and enhances liberation of valuable minerals. In this study, first, the influences of different variables on bulk strength reduction of microwave treated ores have been investigated. Nine different binary ore models were constructed by randomly disseminating 10 vol.% microwave absorbing minerals in transparent matrices. Computational simulations of heating, thermal damage and unconfined compressive strength (UCS) tests on the conceptual binary ores have been undertaken by using finite-difference modelling techniques. The influence of thermo-mechanical properties of minerals on strength reduction of microwave treated ores was examined. It was shown that in general the thermal properties of the microwave absorbing mineral and the mechanical properties of the transparent matrix have the most significant effect on the strength reduction. Binary ores containing a microwave absorbing mineral that has a high thermal expansion coefficient in a strong transparent matrix achieved higher reductions in strength. The influence of absorbent phase grain size on strength reduction of ores was also quantified. It was shown that for the same energy inputs and mineral types, the reductions in strength were much higher in coarse-grained ores. It has also been shown that for the same mineralogy and treatment condition, ores with poorly disseminated heated phase achieved much higher strength reduction. The effect of microwave treatment on the mechanical state of an ore sample was also examined. It was demonstrated that unconfined compressive strength is less sensitive to microwave-induced micro-fractures and found to be a poor descriptor of liberation behaviour. A new method of characterizing damage in microwave treated ore using a continuum approach was developed. The method measures the damage around the grain boundary regions during the heating process. Using the method, it was possible to elucidate in detail the influences of power density, mineralogy, ore texture on microwave treatment of ore. It was shown that the amount of grain boundary damage incurred at a specific power density and energy input is dependent both on the ore mineralogy and its texture. The energy inputs that were required for significant (> 10%) grain boundary damage in the ores range from 0.09 to 7.06 kWh/t depending on the power density applied, the ore mineralogy and its texture. It was also shown that for a given mineralogy and ore texture there is a power density level below which no further increase in grain boundary damage is possible by increasing exposure time. The effect of pulse repetition frequency on grain boundary damage was also elucidated using the method. It was found that high pulse repetition frequencies (³ 50 Hz) resulted in an amount of grain boundary damage that was indistinguishable from that caused by continuous wave operation for a fixed energy input. It has also been shown that for a fixed microwave energy input the best result would be obtained by using the lowest possible pulse repetition frequency and highest peak pulse power. The effect of microwave treatment of ores at different treatment conditions on the extent of damage and crack pattern was also investigated in detail using bondedparticle model (BPM). It has been shown that the amount of micro-cracks and also the cracks pattern in an ore sample after microwave treatment significantly depend on its mineralogy, microwave treatment condition (power density) and absorbent phase grain size. It has also been shown that a minimum power density is required to localize damage around the grain boundary in an ore sample. This minimum power density was found to strongly depend on the ore mineralogy and its texture. Initial simulation test work concerning the effect of microwave treatment on liberation of minerals is also presented. It has been shown that microwave irradiation considerably changed the fracture pattern of an ore in simulated single particle crushing. The fracture pattern of the ore treated at high power density (Pd = 0.1 kW /mm3abs for 1 ms) was along the grain boundary and the absorbent mineral was intact. In the ore treated at lower power density for the same energy input (Pd = 1 W/mm3abs for 0.1 s) both intergranular and transgranular fractures were observed. However, in all cases the fracture patterns were preferentially localized around the grain boundary compared to that of the untreated ore.
AFRIKAANSE OPSOMMING: Vorige studies het getoon dat mikrogolfverhitting van mineraalertse tot breuke om die ertskorrelgrense aanleiding gee, omdat die verskillende mineraalfases in die ertsdeeltjies die mikrogolwe verskillend absorbeer, en dus ook verskillend uitsit. Korrelgrensbreuke verminder die vereiste energie vir latere slypwerk, en verhoog die vrystelling van waardevolle minerale. Hierdie studie het eerstens die uitwerking van verskillende veranderlikes op die algehele sterktevermindering van mikrogolfbehandelde ertse ondersoek. Hiervoor is nege verskillende binêre ertsmodelle vervaardig deur mikrogolfabsorberende minerale met ʼn volumepersentasie van 10% lukraak in deursigtige matrikse te versprei. Met behulp van eindigeverskilmodelleringstegnieke is berekeningsimulasies van verhitting, warmteskade en onbegrensde druksterkte (“unconfined compressive strength”) op die konseptuele binêre ertse uitgevoer. Die invloed van termomeganiese mineraaleienskappe op die sterktevermindering van mikrogolfbehandelde ertse is eerste onder die loep geneem. Daar is bevind dat die warmte-eienskappe van die mikrogolfabsorberende mineraal, en die meganiese eienskappe van die deursigtige matriks, die beduidendste uitwerking op sterktevermindering het. Binêre ertse wat ʼn mikrogolfabsorberende mineraal bevat met ʼn hoë warmte-uitsettingskoëffisiënt in ʼn sterk deursigtige matriks, het groter sterkteverminderings getoon. Die invloed van korrelgrootte in die absorbeerfase op die sterktevermindering van ertse is volgende versyfer. Die studie het getoon dat, op grond van dieselfde energie-insette en mineraalsoorte, grofkorrelrige ertse groter sterktevermindering ondergaan het. Eweneens is bewys dat, met dieselfde mineralogie en behandelingsomstandighede, ertse met ʼn swak verspreide verhittingsfase ook groter sterktevermindering ervaar. Die uitwerking van mikrogolfbehandeling op die meganiese toestand van ʼn ertsmonster is boonop ondersoek. Die studie het getoon dat onbegrensde druksterkte minder gevoelig vir mikrogolfgeïnduseerde mikrobreuke is, en as ʼn swak aanwyser van vrystellingsgedrag beskou word. ʼn Nuwe metode om skade by mikrogolfbehandelde ertse te tipeer is gevolglik met behulp van ʼn kontinuumbenadering ontwikkel. Dié metode meet die skade rondom die korrelgrens gedurende die verhittingsproses. Deur middel van voormelde metode was dit dus moontlik om die invloed van kragdigtheid, mineralogie en ertstekstuur op die mikrogolfbehandeling van erts deeglik te ondersoek. Daar is bevind dat die mate van korrelgrensskade by ʼn bepaalde kragdigtheid en energie-inset, van sowel die ertsmineralogie as ertstekstuur afhang. Na gelang van die toegepaste kragdigtheid, die ertsmineralogie en ertstekstuur, het die vereiste energie-insette vir beduidende (>10%) korrelgrensskade van 0,09 tot 7,06 kWh/t gewissel. Dit het voorts geblyk dat enige bepaalde mineralogie en ertstekstuur oor ʼn minimum kragdigtheidsvlak beskik, onder welke vlak geen verlenging in blootstellingstyd enige verdere korrelgrensskade kan veroorsaak nie. Die uitwerking van pulsherhaalfrekwensie op korrelgrensskade is ook met behulp van bogenoemde metode verklaar. Die studie het getoon dat, op grond van ʼn vaste energie-inset, hoë pulsherhaalfrekwensies (≥50 Hz) en gelykgolfwerking presies dieselfde hoeveelheid korrelgrensskade tot gevolg het. Volgende is daar met behulp van ʼn gebondedeeltjiemodel (“bonded-particle model”) noukeurig ondersoek ingestel na die uitwerking van verskillende mikrogolfbehandelingsomstandighede op die hoeveelheid skade en die kraakpatroon by ertse. Die studie het getoon dat die hoeveelheid mikrokrake sowel as die kraakpatroon in ʼn mikrogolfbehandelde ertsmonster in ʼn groot mate van die betrokke erts se mineralogie, mikrogolfbehandelingsomstandighede (kragdigtheid) en korrelgrootte in die absorbeerfase afhang. Daar is ook bevind dat ʼn minimum kragdigtheid nodig is om skade tot die gebied om die korrelgrens te beperk, welke minimum kragdigtheid oënskynlik grotendeels deur die ertsmineralogie en -tekstuur bepaal word. Die studie bevat ook die resultate van aanvangsimulasietoetse oor die uitwerking van mikrogolfbehandeling op mineraalvrystelling. Die toetse het getoon dat mikrogolfbestraling ʼn beduidende verandering tot gevolg het in die ertsbreekpatroon met gesimuleerde enkeldeeltjievergruising. Die breekpatroon van die erts wat by hoë kragdigtheid (Pd = 0,1 kW/mm3abs vir 1 ms) behandel is, het ál langs die korrelgrens gestrek, terwyl die absorberende mineraal nog ongeskonde was. In die erts wat by laer kragdigtheid dog dieselfde energie-inset behandel is (Pd = 1 W/mm3abs vir 0,1 s), is sowel tussenkorrel- as oorkorrelbreuke opgemerk.

Abstract:
During loss-of-coolant accidents (LOCA) and reactivity-initiated accidents (RIA), nuclear fuel rods experience high heating rates that change the microstructure and properties of zirconium cladding materials, which are in forms of stress-relieved, like cold-worked (CW) or recrystallised (RX) microstructure. The present study aimed to determine how different fast heating rates and starting microstructures affect the kinetics of phase transformation, the transformation textures and eventually the mechanical response in the dual-phase region. The LOCA/RIA cycles from heating at 8 to 100C/s to alpha+beta or above beta transus temperature were achieved via resistive heating in an electro-thermal-mechanical tester. Synchrotron X-ray diffraction (SXRD) and electrical resistivity measurements showed that the approach curves of CW Zircaloy-4 shift to higher temperature at faster constant heating rates and change to a new approach curve when changing rates. 2-second holding at two-phase temperature produces identical phase fractions as equilibrium. These observations are consistent with the diffusional character of the phase trans- formation. Heated at 100oCs1, RX samples transform with 2D beta-growth while CW ones show simultaneous beta-nucleation and growth. The difference arises because the fast heating rate helps preserve low-angle grain boundaries (GB) in the CW microstructure up to phase transformation temperature, increasing beta nucleation sites and prevent beta-growth. This gives rise to different textures of RX and CW materials before transformation, producing different textures, which are weak in both cases. However, this difference is enhanced during grain growth and transformation on cooling. Thus, the RX material shows strong final alpha texture with 0002 maxima aligned in TD and tilted 20deg from ND towards TD while the CW reveals an essentially random one. In both RX and CW materials, variant selection does not occur during transformation on heating. During beta-grain growth, although there is variability in beta-textures measured by SXRD and EBSD beta reconstruction, it is clear that variant selection occurs, leading to strengthening of the beta texture. During transformation on cooling, variant selection occurs early in nucleation of the alpha phase from the shared 110 beta GB in the RX condition. The flow stresses of CW Zircaloy-4 in the two-phase regime at a given temperature depend on the heating rates, despite having the same phase fractions. Heated at a slower rate, the material shows an upper yield stress followed by softening behaviour while that heated faster has a smaller yield stress followed by a high work-hardening rate and then stable flowing stresses. The evolution of diffraction elastic strains and intensity suggest the upper yield stress and softening are due to stress-induced transformation of the harder alpha grains into large and isolated softer beta grains. In contrast, the sample heated faster develops an almost continuous film of beta grains along the GB of unrecrystallised alpha-grains which results in early beta-yielding and coherent deformation of the two phases, leading to constant flow stresses. The findings will improve the accuracy of inputs from phase fractions, microstructure and texture of zirconium claddings when modelling LOCA/RIA. A crystal plasticity model should consider the effects of heating rates and cold-work, which are often ignored. The link between deformation, fast heating rates and microstructure evolution might be relevant to other processes like additive layer manufacturing and even forging in the two-phase region.

Abstract:
Inferences regarding pre-colonial southwestern cooking are limited by preservation and the ambiguity of multiple-use features. Documented techniques are stone boiling, pit roasting, boiling in pottery jars, and heating on comals or griddle stones, with fermentation as an additional food-processing category. The plastic nature of pottery allowed the design of vessel forms specifically for cooking, but storage rather than cooking was the original impetus for pottery production in the Sonoran Desert. The subsequent northward spread of pottery technology does appear to coincide with cooking use, despite initial inefficient vessel forms. Theoretical models and experimental studies have linked subsequent changes in vessel shape and surface texture with gains in efficiency once cooking jars were fully embraced by farming households. Fermentation evidence is arguable in the southern Southwest, and the apparent absence in the north is enigmatic. Residue studies and the use of cooking as an integrative framework hold potential for future research.

Abstract:
Polyurethane acrylate oligomer has been synthetized using microwave irradiation as a green chemistry and synthetized using thermal heating for comparison. Using microwave irradiation, it was possible to either synthesize polyurethane acrylate oligomers without catalyst and/or solvent or achieved at a record time representing 1/12 of the reaction time needed for normal thermal heating. Polyurethane acrylate oligomers synthesized using microwave irradiation possess enhanced thermal stability than the thermal heating synthesized one. The crystallinity percentages of microwave-synthesized polyurethanes are higher than the thermal heating-synthesized polymer. Several experimental measurements applied to the samples like X-ray diffraction (XRD), IR spectra, and transmission electron Microscopy (TEM) etc. The overall morphology of the synthesis of polyurethane acrylate oligomers using microwave irradiation was investigated by TEM, which indicated regular, ordered, and homogeneous polymers within nanosized particle distribution. The disappearance of isocyanate bands on IR charts are strong evidence for the success of the preparation processes for polyurethane acrylate oligomers by all used methods.

Abstract:
The development of extremely flexible photovoltaic (PV) devices for energy harvesting and storage applications is currently receiving more attention by the researchers from industries. The presently available energy storage devices are too rigid and extensive and also not suitable for next-generation flexible electronics such as silicon-based solar cells. Thus, the researchers have developed high-performance, lightweight, conformable, bendable, thin, and flexible dependable devices. On the other hand, these energy storage devices require to be functional under different mechanical deformations, for example, bending, twisting, and even stretching. The nanomaterial (TiO2 , ZnO, Ag, etc.) coated fabrics also play a vital role in improving the efficiency of the solar cell (devices) to a great extent. The current chapter provides information about the development of nanomaterials-based flexible photovoltaic solar cell devices for wearable textile industry applications. The fabricated carbon ink printed fabrics such as polyester, cotton woven and nonwoven, and polyethylene terephthalate nonwoven can be used as cathode and heating sources of PV devices. The organic and flexible conductive substrate printed with carbon ink can be utilized as heating source fabrics for wearable electronics devices. The flexible substrate-based photovoltaics (PV) device is mostly used in the textile industries due to its flexibility, environmental friendliness, low cost as well as easy processability. The flexible-wearable photovoltaic devices pave the way to be used for enormous applications in various fields.

Abstract:
Supplemental heating systems for the distal extremities often require a tradeoff between wearability and thermal comfort. Textile-based thermal actuation helps manage this tradeoff by increasing comfort of on-body systems. However, textile-based thermal actuation also presents important limitations in the form of current requirements, control structures, and thermal flux afforded. Further, on-body active thermal control is affected by three intersecting thermal systems: the environment, the human body, and the active heating system. Here, we present lessons learned from iterative development of textile-based wearable systems (V1, V2) designed to heat the distal extremities. Experimental characterization of textile actuator power/temperature relationships and limits; actuator performance in cool ambient temperatures and in on-body conditions; and efficacy of closed-loop duty cycle control of actuated skin temperature are presented, and implications of these characteristics for garment system design are discussed.

Abstract:
The paper presents a new approach to the design and development of textile woven structures with copper yarn content intended for heating systems. Copper is known for its high electrical conductivity, meaning it can easily transfer electrical energy through its surface. This makes copper yarns ideal for heating applications, as they can quickly and efficiently transfer heat to the surrounding environment. In addition to their electrical properties, copper yarns also have good thermal conductivity, which means that they can transfer heat from one surface to another without losing much energy. Copper yarns are also highly durable and flexible, assuring comfort to wear, non-toxic, reliable, and safe which makes them ideal for use in a range of textile performance applications, including clothing and non-clothing systems, with reduced risk of fire or electrical hazards. The analysis of the surface electrical resistivity as a function of the structural parameters of the woven textile structures, namely the distribution and the thickness of the copper yarns in the fabric's weft will highlight the variations between the conductive fabrics developed.

Abstract:
Temperature is an important influencer of homeostatic comfort for humans, and its influence extends beyond life-preservation functions into cognitive and emotional effects. To augment metabolic processes in cold climates, many on-body heating solutions are currently available in the commercial market, ranging from chemical heat packs to electrically heated accessories and clothing. These products typically prioritize heating the body core in extreme conditions. By contrast, the experience of thermal comfort in the band around homeostatic comfort temperatures is much more strongly driven by experience of temperature in the body’s periphery: the hands, feet, and face [1]. Thermal sensitivity is highest in the distal extremities and has been established as the best correlate of overall perception of thermal comfort [2], [3]. In the medical context, this is especially significant in treating vasospastic disorders such as Raynaud’s Syndrome, where a spastic vascular response in peripheral vessels results in an over-reaction to cold temperatures proximal to the thermoneutral zone [4].

Abstract:
Our research has the general objective of combating thermal discomfort and improving the interaction between the user and the space, through the application of new materials. Textiles have been used in architecture since mankind began to build. One of the advantages of their use is that they improve thermal comfort without increasing energy consumption. Our daily life imposes on us a fast pace, and textiles try to keep up with this movement. However, the floors and coverings of the spaces do not reflect this speed. We estimate a benefit referring to an improvement in terms of user's comfort, if our building could adapt to the situations to which it is subjected, reversibly changing according to the circumstances to which it is exposed. We intend to observe Nature, with the aim of presenting strategies, which can contribute to finding alternative solutions, which accompany these changes, especially meteorological ones.The fur, feathers and scales, the body wrapping of animals, function similarly to the skin of humans, and have different functions (protection, communication, sensation, thermoregulation). Analysis of their protective and regulatory functions provide a starting point, for experiments in textiles and buildings. In this research we will focus on animal cooling and heating techniques, to try to find solutions, based on fauna and flora observation, to formulate possible textile and architectural applications. We will also observe some climatic zones with exaggerated characteristics, to understand how the human being has adapted to these places.It is by no means intended to exhaust the subject, however we will indicate some behavioral strategies and anatomical features that help animals regulate their body temperature. Whenever possible trying to correlate with already existing examples in textiles and Architecture. This article analyzes the possibilities of integrating some animal characteristics, in textiles and coatings with the objective of improving its thermal performance. We believe that by changing the color or applying new materials incorporated into the structures of our clothing or the coatings of our buildings, we can achieve our purpose: to improve thermal comfort. The use of darker shades, allow to absorb more solar radiation and heat the human body or the walls of houses. While the use of lighter shades, contribute to a greater reflection of sunlight, which allows to avoid the heating of the surfaces, favoring the reduction of temperature. We intend with this study to understand the dynamics of Nature, to understand how it solves its problems, to understand its general process of efficiency, to observe its diversity and complexity, with the objective of taking advantage of this inexhaustible source of inspiration for Design, for Textiles, for Architecture. It seems possible to improve the thermal comfort of buildings and their occupants through the production and application of responsive materials.

Abstract:
The ongoing COVID-19 pandemic has increased the use of single-use medical fabrics such as surgical masks, respirators, and other personal protective equipment (PPE), which have faced worldwide supply chain shortages. Reusable PPE is desirable in light of such shortages; however, the use of reusable PPE is largely restricted by the difficulty of rapid sterilization. In this work, we demonstrate successful bacterial and viral inactivation through remote and rapid radio frequency (RF) heating of conductive textiles. The RF heating behavior of conductive polymer-coated fabrics was measured for several different fabrics and coating compositions. Next, to determine the robustness and repeatability of this heating response, we investigated the textile’s RF heating response after multiple detergent washes. Finally, we show a rapid reduction of bacteria and virus by RF heating our conductive fabric. 99.9% of methicillin-resistant Staphylococcus aureus (MRSA) was removed from our conductive fabrics after only 10 min of RF heating; human cytomegalovirus (HCMV) was completely sterilized after 5 min of RF heating. These results demonstrate that RF heating conductive polymercoated fabrics offer new opportunities for applications of conductive textiles in the medical and/or electronic fields.
