Bioactive supra decorated thiazolidine-4-carboxylic acid derivatives attenuate cellular oxidative stress by enhancing catalase activity.

A pharmacophoric motif decorated with supramolecular functionalities (TZT) was designed for potential interaction with biological targets. Main insights of this work include the correlation of supra functionalities of TZT with its binding ability to proteins leading to the modulation of their structure and bioactivity as a promising perspective in the field of cellular protection from oxidative stress. To investigate the role of TZT in obliterating oxidative stress at a molecular level, its binding propensity with bovine serum albumin (BSA) and bovine liver catalase (BLC) was characterized using various biophysical methods.

Electrochemical performance of a self-assembled two-dimensional heterostructure of rGO/MoS/h-BN.

We report the preparation and electrochemical performance evaluation of a two-dimensional (2D) self-assembled heterostructure of graphene oxide (rGO), molybdenum disulphide (MoS), and hexagonal boron nitride (h-BN). In the present study, the rGO-MoS-h-BN (GMH) multi-layered GMH heterostructure is fabricated an chemical route. Based on material analysis, the composite consists of bond conformations of C-B-C, Mo-S, C-N, B-N, and Mo-C, indicating the layered stacks of rGO/h-BN/MoS.

Ruthenium-decorated vanadium pentoxide for room temperature ammonia sensing.

Layer structured vanadium pentoxide (VO) microparticles were synthesized hydrothermally and successfully decorated by a facile wet chemical route, with ∼10-20 nm sized ruthenium nanoparticles. Both VO and ruthenium nanoparticle decorated VO (1%Ru@VO) were investigated for their suitability as resistive gas sensors. It was found that the 1%Ru@VO sample showed very high selectivity and sensitivity towards ammonia vapors.

Ecofriendly synthesis and solar photocatalytic activity of S-doped ZnO.

The S-doped ZnO was prepared by new ecofriendly method, which involves simple mechanochemical synthesis followed by thermal decomposition of bisthiourea zinc oxalate (BTZO) powders. The BTZO was characterized by FTIR and TG-DTA analysis while S-doped ZnO crystallite was characterized by XRD, XPS, SEM, EDXS, and photoluminescence (PL) spectra. X-ray diffraction data suggest the single phase wurtzite structure for S-doped ZnO and the incorporation of sulfur expand the lattice constants of ZnO.
