Synthesis of chiral mesoporous silica nanoparticles for the adsorptive removal of the chiral insecticide sulfoxaflor from water.

Mesoporous materials have garnered significant interest because of their porous structure, large surface area and ease of surface functionalization to incorporate the functional groups of choice. Herein, chiral mesoporous silica nanoparticles (CMSNPs) were prepared using quaternary amino silane as the template, tetramethyl orthosilicate as the silica source and proline and cellulose as chiral selector. The developed CMSNPs were characterized by scanning electron microscopy (SEM), transmission electron microscopy (TEM), elemental analysis, Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction analysis, BET surface area analysis and BJH pore size/volume analysis.

A review on chloride induced corrosion in reinforced concrete structures: lab and investigation.

Reinforced concrete (RC) constructions are seriously threatened by chloride-induced corrosion (CIC) and carbonation, which can result in structural degradation, safety issues, and financial losses. Electrochemical methods and microstructural analysis tests are some of the laboratory techniques used to examine key elements of CIC, such as the impact of different variables and the efficacy of mitigation solutions. studies that make use of non-destructive testing, chloride profiling, and half-cell potential measurements offer important new insights into the long-term performance and causes of RC structure deterioration in real-world circumstances.

Synthesis, and study of novel 1,3-diphenylurea derived Schiff bases as competitive α-glucosidase inhibitors.

Diabetes mellitus has become a major global health burden because of several related consequences, including heart disease, retinopathy, cataracts, metabolic syndrome, collapsed renal function, and blindness. In the recent study, thirty Schiff base derivatives of 1,3-diphenylurea were synthesized and their anti-diabetic activity was evaluated by targeting α-glucosidase. The compounds exhibited an overwhelming inhibitory potential for α-glucosidase with higher potency ranging from 2.

Fabrication of a highly efficient CuO/ZnCoO/CNTs ternary composite for photocatalytic degradation of hazardous pollutants.

In the current study, CuO, ZnCoO, CuO/ZnCoO, and CuO/ZnCoO/CNTs photocatalysts were prepared to remove crystal violet (CV) and colorless pollutants (diclofenac sodium and phenol) from wastewater. Herein, sol-gel and co-precipitation methods were used to synthesize CuO and ZnCoO, respectively. The sonication method was used to synthesize CuO/ZnCoO and a CNTs-based composite (CuO/ZnCoO/CNTs).

From molecular salt to layered network: cation-driven tuning of band gap, structure, and charge transport in ABiI (A = Cs, Rb) perovskites.

The increasing demand for eco-friendly and stable optoelectronic materials has led to interest in all-inorganic lead-free halide perovskites. This study reports the synthesis of ABiI (A = Cs, Rb) perovskites a solvothermal technique. The materials crystallize in hexagonal and monoclinic structures, with micrometer-sized particles.

Characterization and antimicrobial activity of a chitosan-selenium nanocomposite biosynthesized using .

Nanobiotechnological approaches can provide effective solutions for overcoming food products' contamination and spoilage. The development of rapid and eco-friendly approaches for synthesizing nanocomposites from chitosan nanoparticles (Cht), Neptune grass "" extract (NG), and NG-mediated selenium nanoparticles (SeNPs) was targeted, with their investigation as potential antimicrobial, antioxidant, and biopreservatives of fresh chicken fillets. SeNPs were biosynthesized with NG, and their conjugates with Cht were composited.

Large-scale sonochemical fabrication of a CoO-CoFeO@MWCNT bifunctional electrocatalyst for enhanced OER/HER performances.

Herein, we have prepared a mixed-phase CoO-CoFeO@MWCNT nanocomposite through a cheap, large-scale, and facile ultrasonication route followed by annealing. The structural, morphological, and functional group analyses of the synthesized catalysts were performed by employing various characterization approaches such as X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and scanning electron microscopy (SEM). The resultant samples were tested for bifunctional electrocatalytic activity through various electrochemical techniques: cyclic voltammetry (CV), linear sweep voltammetry (LSV), and electrochemical impedance spectroscopy (EIS).

Ghatti gum-base graft copolymer: a plausible platform for pH-controlled delivery of antidiabetic drugs.

In the present study, we aimed to develop a novel pH-sensitive polymeric delivery system (GG--PMMA) for antidiabetic therapy grafting ghatti gum (GG) with methyl methacrylate (MMA) chains. The free radical polymerization technique was adopted to graft ghatti gum with methyl methacrylate, using ceric ammonium nitrate (CAN) as a redox initiator. The impact on grafting parameters such as grafting percentage (%) and grafting efficiency (GE), of monomer and initiator concentrations was evaluated.
