Spectrophotometric determination of salbutamol sulphate in bulk and in pharmaceutical formulations

مجلة بغداد للعلوم
A new simple and sensitive colorimetric method has been developed for determination of salbutamol in aqueous solutions. The method is based on the formation of a yellow colored azo dye by diazotization of 2,4-dichloroaniline, followed by a azo-coupling ...

Investigating the Inhibitory Properties of Diazo and Pyrazole‐Carboxamide‐Linked Benzenesulfonamides Against Carbonic Anhydrase Isoforms I, II, IX, and XII

ChemMedChem, Volume 21, Issue 13, 14 July 2026.
Hybrid diazo‐ and pyrazole‐carboxamide benzenesulfonamides emerge as highly potent and selective inhibitors of tumor‐associated carbonic anhydrases. A 3,4‐dichloro‐substituted derivative achieves sub‐2 nM inhibition of hCA IX and displays promising anticancer activity, revealing a valuable scaffold for the development of next‐generation cancer‐targeted

Biochar Bridging Carbon Nitride and Rare Earth Metal Oxide for Boosting Microstructural Characteristics and Visible‐Light Photocatalytic Activity

Advanced Energy and Sustainability Research, Volume 7, Issue 7, July 2026.
The outstanding activity of the g‐C3N4/BC(0.2%)/LaO composite heterostructure led to efficient removal of different organics in photocatalytic reaction. This was attributed to its improved microstructural characteristics, as well as photo absorption, charge separation, and transfer, which were boosted by the bridging role of BC between g‐C3N4 and LaO ...

From brush conformation to 3D Supraparticles: Programmable self‐assembly of polymer‐grafted nanoparticles in emulsion confinement

Bulletin of the Korean Chemical Society, Volume 47, Issue 7, Page 787-800, July 2026.
This review highlights how the conformational adaptability of polymer‐grafted nanoparticles drives their programmable self‐assembly within 3D emulsion droplets. By coupling brush thermodynamics with soft confinement, these dynamic building blocks form hierarchical supraparticles tailored for advanced plasmonics, compartmentalized catalysis, and stimuli‐
