In Silico Analysis of Calotropis procera-Derived Phytochemicals Targeting 3CL Proteoase of SARS-CoV-2.

The coronavirus known as SARS-CoV-2 has enveloped virions with single-stranded positive-sense RNA genome. It infects mammals, including humans, via the respiratory tract. The non-structural protein of coronavirus, main protease (3CLp) is a key enzyme in the disease's progression.

Comparative investigation of tellurium-doped transition metal nanoparticles (Zn, Sn, Mn): Unveiling their superior photocatalytic and antibacterial activity.

In this study, tellurium-doped and undoped metal oxide nanoparticles (NPs) (ZnO, MnO, SnO) are compared, and a practical method for their synthesis is presented. Nanocomposites were created using the coprecipitation process, and comparisons between the three material categories under study were made using a range of characterization methods. The produced materials were subjected to structural, morphological, elemental composition, and functional group analyses using XRD, FESEM in combination with EDS, and FTIR.

Harnessing solar power for enhanced photocatalytic degradation of coloured pollutants using novel Mg-doped-ZnFeO/S@g-CN heterojunction: A facile hydrothermal synthesis approach.

The ability of heterogeneous photocatalysis to effectively remove organic pollutants from wastewater has shown great promise as a tool for environmental remediation. Pure zinc ferrites (ZnFeO) and magnesium-doped zinc ferrites (Mg@ZnFeO) with variable percentages of Mg (0.5, 1, 3, 5, 7, and 9 mol%) were synthesized via hydrothermal route and their photocatalytic activity was checked against methylene blue (MB) taken as a model dye.

A novel organic-inorganic matrix nanofiltration membrane for remediating copper with enhanced thermal stability and mechanical strength.

Membrane separation technology in the last 40 years has experienced impressive growth, displacing conventional separation processes due to inherent advantages such as less capital investment, and energy efficiency and the devices were simple, compact, and modular. In the current work, we aimed to synthesize a thin-sheet nanofiltration membrane using chitosan (CS), poly(vinyl) alcohol (PVA), and montmorillonite nanoclay (MMT) for copper removal from aqueous solution. Thermogravimetric analysis and differential scanning calorimetry were employed to evaluate the thermal stability of a novel organic-inorganic hybrid membrane.

Novel yellowish-green single-phased spinel MgBaAlO:Mn phosphor(s) for color rendering white-light-emitting diodes.

For white light-rendering research activities, interpretation by using colored emitting materials is an alternative approach. But there are issues in designing the white color emitting materials. Particularly, differences in thermal and decay properties of discrete red, green, and blue emitting materials led to the quest for the search of a single-phased material, able to emit primary colors for white light generation.

Green synthesis of tellurium-doped SnO nanoparticles with sulfurized g-C N : Insights into methylene blue photodegradation and antibacterial capability.

The construction of SnO nanoparticles (NPs), specifically Te-doped SnO NPs, using a simple and economical co-precipitation technique has been thoroughly described in this work. NH served as the reducing agent in this procedure, whilst polyethylene glycol served as the capping agent. The primary goals of our work were to investigate the physicochemical properties of the synthesized SnO NPs and assess their potential use as antibacterial agents and photocatalysts.

Development of stable S-scheme 2D-2D g-CN/CdS nanoheterojunction arrays for enhanced visible light photomineralisation of nitrophenol priority water pollutants.

The investigation focused on creating and studying a new 2D-2D S-scheme CdS/g-CN heterojunction photocatalyst. Various techniques examined its structure, composition, and optical properties. This included XRD, XPS, EDS, SEM, TEM, HRTEM, DRS, and PL.

Tailoring of an anti-diabetic drug empagliflozin onto zinc oxide nanoparticles: characterization and in vitro evaluation of anti-hyperglycemic potential.

Diabetes is a serious health issue that can be a great risk factor related to numerous physical problems. A class of drugs "Gliflozin" especially Sodium Glucose Co. Transporter 2 was inhibited by a novel drug, which is known as "empagliflozin".

Solar-Driven Thermocatalytic Synthesis of Octahydroquinazolinone Using Novel Polyvinylchloride (PVC)-Supported Aluminum Oxide (AlO) Catalysts.

The chemical industry is one of the main fossil fuel consumers, so its reliance on sustainable and renewable resources such as wind and solar energy should be increased to protect the environment. Accordingly, solar-driven thermocatalytic synthesis of octahydroquinazolinone using polyvinylchloride (PVC)-supported aluminum oxide (AlO) as a catalyst under natural sunlight is proposed in this work. The AlO/PVC catalysts were characterized by FT-IR, SEM, BET, XRD, and XPS techniques.

Mesoporous Tungsten Trioxide Photoanodes Modified with Nitrogen-Doped Carbon Quantum Dots for Enhanced Oxygen Evolution Photo-Reaction.

Nanostructured photoanodes are attractive materials for hydrogen production via water photo-electrolysis process. This study focused on the incorporation of carbon quantum dots doped with nitrogen as a photosensitizer into porous tungsten trioxide photoanodes (N-CQD/-WO) using a surfactant self-assembly template approach. The crystal structure, composition, and morphology of pure and N-CQD- modified porous WO photoanodes were investigated using scanning electron and transmission microscopy, X-ray diffraction, and X-ray photoelectron spectroscopy.
