Environment friendly, flexible, and robust sensors have attracted considerable research attention due to their potential for a wide range of devices in energy generation harvesting, sensing, biomedical applications. In this manuscript, we demonstrate lead-free, solution processed flexible piezoelectric generator based on nanocomposite film, consisting MgO nanoparticles sizes around <50 nm, embedded poly(vinylidene difluoride) [PVDF] its copolymer with trifluoroethylene, that is, P(VDF-TrFE)...
Conventional ceramic based piezoelectric materials are brittle, which restricts their use in energy harvesting where flexibility is required. Polymer counterparts flexible but exhibit comparatively reduced electrical output. Here, we provide a method that overcomes these challenges through design of composites comprised polymer matrix (PVDF-TrFE) and filler nanoparticles (niobium-doped Pb(Zr,Ti)O3). Nanoparticles were functionalized with trimethoxysilylpropyl methacrylate (TMSPM) promotes...
Low-grade thermal energy, either from waste heat or natural resources, constitutes an enormous energy reserve that remains to be fully harvested. Harvesting low-grade is challenging because of the low Carnot efficiency. Among various harvesting mechanisms available for capturing (temperature less than 100 °C), thermomagnetic effect has been found quite promising. In this study, we demonstrate a scalable harvester architecture exhibits 140% higher power density compared previously published...
The pandemic caused by SARS-CoV-2 (SCoV-2) has impacted the world in many ways and virus continues to evolve produce novel variants with ability cause frequent global outbreaks. Although advent of vaccines abated burden, they were not effective against all SCoV-2. This trend warrants shifting focus on development small molecules targeting crucial proteins viral replication machinery as therapeutic solutions. PLpro is a enzyme having multiple roles during life cycle well-established drug...
P(VDF-TrFE), the best known ferroelectric polymer, suffers from a rather low piezoelectric response as well poor electrical fatigue life, hampering its application potential.
We have prepared the composites of a room temperature Nematic Liquid Crystals and Single-Walled Carbon Nanotubes. Effect dispersion nanotubes on various dielectric electro-optic parameters host nematic liquid crystals were investigated. The changes in (viz: relative permittivity, anisotropy, switching threshold voltage splay elastic constant) observed for composite systems. filled cells been probed under applied bias electric field it enhanced ordering crystal molecules which results overall...
The Escherichia coli dgt gene encodes a dGTP triphosphohydrolase whose detailed role still remains to be determined. Deletion of creates mutator phenotype, indicating that the dGTPase has fidelity role, possibly by affecting cellular dNTP pool. In present study, we have investigated structure Dgt protein at 3.1-Å resolution. One obtained structures revealed hexamer contained two molecules single-stranded DNA. presence DNA caused significant conformational changes in enzyme, including...
We have prepared the composites of a room temperature nematic liquid crystal mixture by dispersing small fractions Multi-Walled Carbon Nanotubes into its matrix. The electro-optical and dielectric properties samples were investigated. effect on various display parameters host was observed. variations in some like anisotropy, threshold voltage, splay elastic constant activation energy been observed for composite systems with respect to pure mixture. Dispersion enhanced order host, resulting...
A reverse-phase high pressure liquid chromatographic method with an optimised extraction procedure for the quantitative estimation of bergenin and (+)-afzelechin in different parts popular Indian herb Paashaanbhed (Bergenia ligulata Yeo) has been developed. The is sensitive, precise gives more than 99% recovery active constituents. rhizomes plant were found to contain higher concentrations (0.907%w/w) (0.168% w/w) other plant. presence these constituents was also estimated polyherbal...
Abstract Precise polarized Raman measurements of 2‐chloropyridine (2Clpy) in the region 560–1060 cm −1 and 3‐chloropyridine (3Clpy) 680–1080 at different concentrations mole fraction methanol were made to calculate isotropic part spectra, which has contributions only from vibrational dephasing. A detailed analysis spectra was carried out see variation peak position linewidth. The dephasing is mode specific. trigonal bending 3Clpy two components when it mixed with methanol. relative...

Today is the era of intelligence in machines. Through Artificial Intelligence, machines have started to mimic various human traits today. One instance this artificial conversational entities, also called chat bots, which are computer programs capable carry out near-natural conversation with people. Chatbots important because they one most prolific examples Human Computer Interaction (HCI). These mainly serving as personal assistants these days. We programmed two working bots using different...
ABSTRACT Polymers comprised of redox‐active organic radicals have emerged as promising materials for use in a variety electronics, including fast‐charging batteries. Despite these advances, relatively little attention has been focused on the diversification families that are commonly incorporated into polymer frameworks, with most radical polymers being nitroxide radicals. Here, we report two new examples prepared via ring‐opening methathesis polymerization containing 6‐oxoverdazyl and...
