Abstract: Cadmium Zinc selenide Cd1-xZnxSe (x = 0.6) thin film deposited on to glass substrate by solution growth technique. Deposition parameters were optimized. Structural, optical and surface morphology properties of as-deposited thin film were studied by XRD, UV-VIS, SEM and AFM, respectively. X-ray diffraction (XRD) analysis indicated polycrystalline cubic structure. SEM and AFM pattern revealed that, the film was uniformly deposited by crystalline grains over the entire glass substrate. UV-VIS absorption spectra were recorded within the range of 300-1100 nm. It shows high absorption with direct optical band gap energy equal to 2.39 eV. The electrical resistivity shows semiconducting behavior of the film.

Abstract: Background: Materials of physical size less than approximately 100 nanometres are classified as nanomaterials. They have been of advantage to mankind owing to unique properties significantly different from those of bulk materials. Nanoparticles can be composed of various materials including metals or silica like silica nano particles which are of interest in this study having at least one dimension less than 100 nanometres and exhibit.....

Abstract: In this context, the construction of efficient, stable and visible-light-active photocatalysts lies at the heart of sustainable wastewater treatment. Herein, we report on the rational design and synthesis of a new tetradentate ligand, 2,2'-(pyrazine-2,5-diyl)bis(4,5-dichlorophenol) (DPPD), and corresponding bimetallic Cu(II) complex, [Cu2(DPPD)(OAc)2(H2O)2]. The structural integrity of species was validated in detail via 1H/13C-NMR, FTIR, and High-Resolution Mass Spectrometry (HRMS). Optical analysis showed a substantial bandgap narrowing from 2.58 eV to 1.43 eV (ligand and complex) in optical studies as a result, leading to remarkable visible light harvesting. Conventional electrochemical investigations....

Abstract: Endophytic fungi are increasingly recognised as prolific producers of structurally diverse secondary metabolites with significant pharmacological potential. In the quest for novel bioactive agents from natural sources, this study investigates the antioxidant capacity of endophytic fungi isolated from the medicinal plant Breonadia salicina. Fungi were isolated from surface- sterilised leaf and stembark tissues and cultured on PDA media. Ethyl acetate extracts of the fungal isolates were screened for antioxidant activity using the DPPH radical scavenging assay, with IC₅₀ values....

Abstract: Background The outbreak and transmission of infectious diseases can be prevented by the regular disinfection
of high-touch surfaces. Such surfaces often harbour disease-causing microorganisms (pathogens) but through disinfection, the pathogens are eliminated or inactivated, thereby decontaminating the surfaces. A disinfectant is a chemical agent or substance that destroys or irreversibly inactivates pathogens like bacteria, viruses and fungi on surfaces of inanimate objects.....
