Abstract:-The present day protective clothing system used by the defence sectors are vulnerable to modern weapons and also have some inherent weaknesses. A textile material developed to fulfill the requirements of defence such as camouflage, flame proof, ballistic, etc are called as the defence textiles. The fundamental requirements for all the fabrics for defence includes personal protective equipment for military personnel during non-combat, combat and emergency operations, critical survival situations, military uniforms, performance requirements, etc. In addition to protection, the gear must have the properties for high resistance to sun, resist mildew, withstand abrasion, tears and breaks, etc. Developments in the weapons and surveillance technologies are prompting innovations in individual protection equipment and battle related systems and structures. Defence clothing requirements are becoming more complex as the defence personnel have to perform at unprecedented levels. Research continues to develop innovative combat clothing for the use of soldiers.

Abstract: Plasmonic NPs have a variety of applications in electronics, optoelectronics, biomedics and medicine but, NPs such as gold and silver are very costly. We can explore the same plasmonics properties by adding other materials into it. In recent years, the latest trend is to use magnetic field with plasmonic properties. To achieve the enhancement in optical properties with magnetic nature, the study appeals the combination of noble metals with magnetic (ferromagnetic) materials which leads to highly appealing nanostructures with increased functionalities. This new field emerging by the combination of magnetic and plasmonic NPs is called magneto-plasmonics. The use of complex structures made from ferromagnetic (Fe, Co and Ni) materials and noble metals (Au and Ag) have been proposed. The main aim is to use the magnetism and plasmonic together to enhance the optical properties. From the literature survey it is very clear that a sporadic research findings both theoretical and experimental in the field of magnetoplasmonics have been reported by the researchers but still there are various gaps about the tunability of optical properties of magneoplasmonic nanostructures with their parameters like materials, shapes, size, etc. which are unrevealed yet and need systematic investigations in order to make most out of these magnetoplasmonic nanostructures in different applications.

Abstract: The mechanical property of metal oxide reinforced epoxy based Polymer Matrix Composites (PMCs) is studies here. Epoxy composites filled with ZnO, ZrO2 and CeO2 in various content of 0-3 wt% were prepared using the casting technique. The entire test was done in room temperature and ASTM standard. Experimentally the synthesis has been carried out. All the materials have been under go some mechanical tests. Density, hardness, tensile, flexural, compression and impact strength of neat epoxy were found to increase with the metal oxide content up to certain wt%. It was observed that metal oxide is not beneficial in improving the impact strength of neat epoxy. This paper also highlights the possible reasons for variation in the mechanical properties of developed polymer composites.

Abstract: The present work focuses on the study of improving the self-healing phenomenon of TPU reinforced with small amounts of MWCNTs. The selfhealing aliphatic TPU was reinforced with 1.3 mg of MWCNTs and the samples were exposed to UV radiation to accelerate the self-healing process. A decrease in crystallite size and increase in crystallinity of TPU is observed after addition of CNTs. Improved physical inter-locking between TPU and CNTs was confirmed thermo-gravimetric analysis. This indicates significant decrease in the thermal degradation tendency of TPU-CNT thin film. Remarkable changes in the morphology of scratch after CNT addition was observed, thus, indicating enhanced healing on UV exposure. The TPU-CNT gets heated rapidly resulting in the diffusion of TPU chains at the broken interface and their re-entanglement in order to heal the crack, where CNT’s act as bridging medium. Thus, it can be said here that during healing process CNT acts as an effective heat-transfer unit when interacting with the matrix.

Abstract: In this study, weaver ant silk fibroin / highly conductive polymer (viz. polypyrrole and polyaniline) composites (WSF/PPY and WSF/PANI) were successfully prepared by in situ polymerisation, using silk fibroin from the weaver ant and conductive polymers. The properties of WSF/polymer composites have been investigated using optical microscope, Scanning Electron Microscope (SEM), Fourier Transform Infra Red (FTIR) spectroscopy and UV-visible spectroscopy. Surface morphology studies indicate that the conducting layer on the fibers is relatively compact and uniform. The FTIR analysis indicated the successful coating of the polymer by shifting of peaks in the spectra, and the spectrum for WSF showed amide I, amide II, amide III, C-H and C-O peaks, which were attributed to random coil and β-sheet conformation in the protein structure. The observed conductivity for the composites are in the range of 0.098856S cm- 1, 0.1Scm-1 and the average diameters are found to be 75±50nm, 70±25nm for PPy/WSF and PANI/WSF respectively. Nevertheless, the prepared composites are having good compatibility, the results of this work provided an evidence for the conducting properties and it may be a potential alternative matrix for application in wide areas such as medicine, defence, electronics, etc.

Abstract: In this work, a cylindrical gate-all-around (CGAA) FET (field-effect transistor) structure with Indium Arsenide (InAs) nanowire is used as channel instead of silicon nanowire, and aluminium oxide is used as the gate dielectrics instead of silicon dioxide. The performance of this setup was demonstrated using ATLAS simulator of Silvaco TCAD software. Indium Arsenide is chosen due to its high electron velocity, high saturation velocity and low contact resistance, whereas, aluminium oxide is chosen because of its higher permittivity. Simulation results indicate that the proposed combination is superior to the CGAA structures having channel-gate dielectrics that use combinations of silicon-silicon dioxide and Indium Arsenide-silicon dioxide. The effects of variation of nanowire radius, channel length and oxide thickness on the output and transfer characteristics curves, and also on the performance parameters such as maximum drain current, maximum transconductance, on resistance and inverse subthreshold slope are investigated to show the superiority of the proposed structure.
