Copper oxide (CuO) nanosheets (NSs) have been synthesized using improved chemical bath deposition(CBD) method and used as energy materials in supercapacitor devices. The quality of CuO-NSs wereinvestigated using different techniques such as, cyclic voltammetry, galvanostatic charge/dischargemeasurements, and electrochemical impedance spectroscopy. The structure, composition, andmorphology of CuO-NSs were examined by X-ray powder diffraction (XRD), field-emission scanningelectron microscopy (FE-SEM), energy dispersion spectrum (EDS). CuO-NSs device exhibited maximumspecific capacitance about 564 Fg 1 at 5 mV/s. Antibacterial properties of CuO-NSs with Bacillus subtilisand Salmonella typhimurium have shown promising prospects for the development of antibacterialagents.

Present investigation deals with the effect of electron beam irradiation on the photoelectrochemicalproperties of cadmium selenium telluride (CdSe0.6Te0.4) thin films. Initially, CdSe0.6Te0.4 thin films wereelectrodeposited on fluorine doped tin oxide (FTO) coated glass and stainless steel substrates. Later,these CdSe0.6Te0.4 thin films were irradiated with high energy electron beam(10 MeV) of different dosesfrom 10 to 30 kilograys (kGy). The effect of electron beam irradiation on different physico-chemicalproperties of CdSe0.6Te0.4 thin films such asmorphological, structural, optical and photoelectrochemicalhas been investigated. It is observed that, the electron beam irradiation treatment considerably affectsthe properties of CdSe0.6Te0.4 thin films. The surface morphology of CdSe0.6Te0.4 thin films was changedfrom cauliflowers to nanoflowers, nanoroses and interconnected nanoflakes with doses of electronbeams. Furthermore, the effect of electron beam irradiation on photoelectrochemical properties ofCdSe0.6Te0.4 films was investigated. It is interesting to note that, the photoelectrochemical (PEC)properties of CdSe0.6Te0.4 thin films are extensively affected by electron beam irradiation. Thephotoconversion efficiency values of CdSe0.6Te0.4 films for different doses of electron beam are found tobe 0.9%, 1.1%, 2.0% and 1.5%, respectively.

The Gaussian-based 3D-QSAR studies for 58 selective COX-2 (cyclooxygenase-2) inhibitors belonging to benzopyran chemical class were performed. Partial least squares analysis produced statistically significant model with (R training 2 = 0.866) and predictability (Q training 2 = 0.66, Q test 2 = 0.846). The 3D-QSAR model includes steric, electrostatic, hydrophobic, and hydrogen bond acceptor field indicators, whereas the potential field contributions indicate that the steric and hydrophobic features of the molecules play an important role in governing their biological activity. A molecular docking simulation and protein–ligand interaction pattern analysis reveal the importance of Tyr-361 and Ser-516 of the COX-2 active site for X-ray crystal structures and this class of molecules. Thus the combined approach of ligand-based and structure-based models provided an improved understanding in the interaction between benzopyran chemical class and COX-2 inhibition, which will guide the future identification of more potent anti-inflammatory drugs.
