AbstractThe performance of electrochemical water splitting is very much affected by the sluggishness of oxygen evolution reaction (OER) process. Therefore, design and development of low cost, stable and active catalyst for OER process is a challenging issue. In this study we have used cone-shaped pencil graphite (PG), which is commonly used for wri...

We have designed and synthesized a novel magnetic cluster containing low-spin (S = 1/2) Fe3+ and spin-1/2 Cu2+ ions, which incorporates competing ferromagnetic Fe–Cu interactions and antiferromagnetic Fe–Fe and Cu–Cu interactions. This is achieved with the help of a cyanido-bridged hexanuclear iron-copper cluster [{Fe(Tp)(CN)3}4{Cu(MePz)2}2] follow...

AbstractIn this work, it is demonstrated that visible-light photocatalytic activity for degrading methyl orange (MO) could be improved by co-milling of TiO2 (Degussa P25) with thiourea. The photocatalysts have been prepared by combined mechanochemical/thermal synthesis. Structures and morphology of the as-prepared TiO2 nanoparticles were characteri...

Technological advancement towards the quantum era requires secure communication, quantum computation and ultra-sensitive sensing capabilities. Layered quantum materials (LQMs) have remarkable optoelectronic and quantum properties that can usher us into the quantum era. Electron microscopy is the tool of choice for measuring these LQMs at an atomic ...

Removal of antibiotics detected in wastewater or natural aquatic systems by regular municipal treatment is challenging. Photocatalysis is considered to be the most well-known and green strategy for such removal. However, the catalytic efficiency is restricted by UV radiation dependence, fast electron-hole recombination, and low porosity/surface are...

This paper describes the preparation and characterization of nanocrystalline CdxPb1−xS thin films by chemical bath deposition method with different Pb and Cd solute ratios. XRD, HRTEM and SAED patterns show the nanocrystalline nature of films with the co-existence of cubic, hexagonal and tetragonal phases, while micro-Raman spectra reveals the pres...

In this work, nickel sulphide (NiS)–reduced graphene oxide (rGO) (NiS–rGO) has been used as a cathode in dye-sensitized solar cell (DSSC). The cathode has been prepared via liquid phase deposition technique assisted with modified Hummer’s method and spin-coating technique. The effect of annealing temperature on the properties of NiS–rGO has been re...

Bismuth tartrate (BiT) is successfully synthesized by the sol–gel method. The photocatalytic performance was evaluated by decolourization of anthraquinone-based Reactive Blue 19 (RB19) dye that represents a model of organic pollutant. The X-ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscopy and energy-dispersive ...

The key challenge in tissue engineering is to develop structures with sufficient characteristics that will replicate the natural extracellular matrix (ECM) to promote tissue regeneration. Copper and manganese minerals substituted hydroxyapatite (CuMn-HA)/chitosan (CTS)–polyvinyl pyrrolidone (PVD) were fabricated by sol–gel and solvent casting techn...
