Vitiligo, a common skin disorder, is characterized by the loss of functional melanocytes resulting in the depigmentation of skin. Previous studies have demonstrated molecular and architectural alterations in the epidermal keratinocytes upon loss of melanocytes. The physiological implications of these "altered" keratinocytes are yet not known. We investigated the wound healing efficiency of lesional vs nonlesional skin in 12 subjects with stable nonsegmental vitiligo using histological and ultras...

Carbon nanospheres (CNSs) couple large surface area, high electrical conductivity, thermal stability and variable surface functionalities with controllable size, band gap and chemical properties. In the present study, mono-dispersed CNSs were synthesized by hydrothermal process from three saccharides—glucose, xylose (monosaccharides) and sucrose (disaccharide). The synthesized CNSs were characterized using XRD, FTIR, SEM, TEM and UV–visible spectroscopy. Xylose gives the smallest CNSs for the sa...

Abstract Transition metal carbides (TMCs) have emerged as excellent catalyst support for fuel cell applications. They can also be employed as supercapacitors and for efficient fuel production (H2). Recently, TMCs are being explored as photocatalysts due to the similar electronic configuration as that of the noble metals (Pt, Pd, etc.). But, non-availability of semi-conducting characteristics in TMCs hinders the generation of excitons required for the photo-oxidation of organic pollutants. In thi...

Abstract A facile single step chemical method is reported for the synthesis of Zr doped ZnS nanopowder and its photocatalytic performance has been studied. The average crystallite size of the synthesized powder estimated from X-ray diffraction (XRD) is nearly 1.1 nm. Transmission electron microscopy (TEM) study shows that nanoparticles are agglomerated having a particle size of nearly 10 nm. The optical band gap of ZnS and Zr-doped ZnS, estimated with the help of UV–visible spectroscopy, is 3.7 ...

Abstract In this reported work, the potential application of MnO2 nanopowder for photocatalytic and the electrocatalytic applications is explored. The MnO2 nanopowder has been synthesized through sonochemical route using KMnO4 and poly-ethylene glycol as the reducing agent. Structural and optical analysis (XRD, TEM, FTIR, XPS and UV–visible) confirmed the formation of nanocrystalline MnO2 network. The adsorption and photocatalytic performance of synthesized MnO2 was tested for degradation of met...

The rapid urbanisation and high population density of all nations requires the development of sustainable security systems at all times which can protect people and their belongings against burglaries. A zero-power consuming or self-powered intruder system (SPIS) was reported for the first time using a flexible piezoelectric composite film nanogenerator (FPCF-NG) made up of polydimethylsiloxane (PDMS) and a solid state reaction (SSR) based dual perovskite system, i.e. (1 − x)K0.5Na0.5NbO3−xBaTiO...

Abstract Undoped, Ca-doped NaNbO3 and its heterostructure with g-C3N4 have been successfully prepared through chemical route followed by heat treatment. All the prepared samples were analysed using XRD, FESEM, TEM and XPS spectroscopy for various structural and surface features. Further, absorbance (UV–visible) and photoluminescence (PL) spectroscopy revealed the bandgap narrowing and emission quenching, respectively as a result of doping and formation of heterojunction. Ca doped NaNbO3-C3N4 sam...

Abstract Photocatalysis has emerged as a vital tool for purification of waste water and also to obtain alternate fuels (H2) through water splitting. TiO2, ZnO and other non-carbide systems (ZnS, metallic nanoparticles (NPs), etc.) have been studied thoroughly to enhance their photocatalytic performances through doping and the formation of heterojunctions. But, niobium carbide (NbC) is gaining interest of researchers due to its ability to catalyze electrochemical reactions (hydrogen evolution rea...

Abstract Nano transition metal carbides (TMCs) have emerged as materials of great interest for different catalytic applications in fuel cells and also as catalysts for photo-treatment of organic effluents in industrial waste water. For both the catalytic phenomenon, the charge transfer pathways between the TMC and the surrounding carbon are of significant importance. In present work, well characterized nano powders of Tantalum Carbide (TaC) have been used as a model system to understand the effe...
