Photoelectrocatalytic Surfactant Pollutant Degradation and Simultaneous Green Hydrogen Generation.

For the first time, we demonstrate a photoelectrocatalysis technique for simultaneous surfactant pollutant degradation and green hydrogen generation using mesoporous WO/BiVO photoanode under simulated sunlight irradiation. The materials properties such as morphology, crystallite structure, chemical environment, optical absorbance, and bandgap energy of the WO/BiVO films are examined and discussed. We have tested the anionic type (sodium 2-naphthalenesulfonate (S2NS)) and cationic type surfactants (benzyl alkyl dimethylammonium compounds (BAC-C12)) as model pollutants.

High-performance EMI shielding effectiveness of FeO-3D rPC nanocomposites: a systematic optimization in the X-band region.

In this work, the microwave absorption (MWA) performance of a FeO-3D reduced porous carbon nanocomposite (3D rPC NC) in the X-band region is reported. Three different shields are fabricated by altering the ratio of FeO nanoparticles (NPs) and 3D rPC and evaluating their microwave (MW) shielding performance with appropriate in-wearing instruments due to their minimum thickness. The chemical interaction between FeO NPs and 3D rPC is examined from chemical composition analysis of FeO-3D rPC (1 : 2 ratio), which is confirmed by the presence of the Fe-O-C bond in the O 1s spectrum obtained from XPS analysis and subsequent analysis using FESEM images.

Multifunctional ZnO/SiO Core/Shell Nanoparticles for Bioimaging and Drug Delivery Application.

Semiconducting nanoparticles with luminescent properties are used as detection probes and drug carriers in in-vitro and in-vivo analysis. ZnO nanoparticles, due to its biocompatibility and low cost, have shown potential application in bioimaging and drug delivery. Thus, ZnO/SiO core/shell nanoparticle was synthesised by wet chemical method for fluorescent probing and drug delivery application.

Perovskite Solar Cells: A Porous Graphitic Carbon based Hole Transporter/Counter Electrode Material Extracted from an Invasive Plant Species Eichhornia Crassipes.

Perovskite solar cells (PSCs) composed of organic polymer-based hole-transporting materials (HTMs) are considered to be an important strategy in improving the device performance, to compete with conventional solar cells. Yet the use of such expensive and unstable HTMs, together with hygroscopic perovskite structure remains a concern - an arguable aspect for the prospect of onsite photovoltaic (PV) application. Herein, we have demonstrated the sustainable fabrication of efficient and air-stable PSCs composed of an invasive plant (Eichhornia crassipes) extracted porous graphitic carbon (EC-GC) which plays a dual role as HTM/counter electrode.

Growth of 'W' doped molybdenum disulfide on graphene transferred molybdenum substrate.

In the present study, a novel method has been carried out to grow tungsten (W) doped molybdenum disulfide (MoS) on the graphene transferred TEM grid in a chemical vapor deposition (CVD) setup. Tungsten trioxide (WO) has been used as a source for 'W' while 'Mo' has been derived from Mo based substrate. Different experimental parameters were used in this experiment.
