Sulfonamides have a special role on medicine due to their broad biological activities, as bacterial infections, diabetes mellitus, oedema, hypertension prevention and treatment. In addition, sulfonamides are also useful in herbicides and pesticides. Herein, we communicate an efficient strategy for the preparation of sulfonamides via NH I-mediated amination of sodium sulfinates. This new method provides a general and environmentally friendly access to sulfonamide compounds and tolerates a wide range of functional groups.

The present work focuses on the production of sildenafil co-evaporates loaded emulgels as topical dosage forms for the treatment of premature ejaculation and erectile dysfunction. Topical administration of sildenafil citrate (SILD) co-evaporates is expected to improve the bioavailability profile of the drug and to avoid the severe side effects accompanying the traditional SILD dosage forms, especially for prohibited cardiovascular cases. Firstly, the solubility of SILD was improved via solid dispersion via co-evaporation technique using PEG-5KDa and PVP-K90 as hydrophilic carriers.

In this work, we investigate the development of polymer electrolytes for sodium batteries based on sulfonamide functional polymer nanoparticles (NaNPs). The synthesis of the polymer NaNPs is carried out by emulsion copolymerization of methyl methacrylate and sodium sulfonamide methacrylate in the presence of a crosslinker, resulting in particle sizes of 50 nm, as shown by electron microscopy. Then, gel polymer electrolytes are prepared by mixing polymer NPs and different organic plasticizers including carbonates, glymes, sulfolanes and ionic liquids.

The presence of pharmaceuticals in nature systems poses a threat to the environment, plants, animals, and, last but not least, human health. Their transport in soils, waters, and sediments plays important roles in the toxicity and bioavailability of pharmaceuticals. The mobility of pharmaceuticals can be affected by their interactions with organic matter and other soil and water constituents.

In the electrocatalytic (EC) degradation process, challenges such as inefficient mass transfer, suboptimal mineralization rates, and limited current efficiency have restricted its broader application. To overcome these obstacles, this study synthesized spherical particle electrodes (FeNi@BC) with superior electrocatalytic performance using a bio-inspired preparation method. A three-dimensional electrocatalytic oxidation system based on FeNi@BC electrode, EC/FeNi@BC, showed excellent degradation efficiency of sulfamethoxazole (SMX), reaching 0.

The removal of organic pollutants from water is significantly important as they have harmful effects on the ecosystem. Heterogeneous photocatalysis is a potential technique for the removal of organic pollutants from the wastewater. In this article, zinc oxide (ZnO) and samarium oxide (SmO) nanoparticles and ZnO-SmO nanocomposite (ZS) were synthesized by the co-precipitation method.
