A major challenge in green chemistry is developing practical metal-catalyzed reactions in water, a safer and more sustainable medium than toxic organic solvents. This research has designed polymer-supported copper catalysts capable of assembling into micellar nanocatalysts in water having 175 nm diameter and low polydispersity. Copper-catalyzed azide−alkyne cycloaddition (CuAAC) was highly efficient in aqueous media. …

When Miss Khuyen T. Nguyen, a Ph.D. student, posed a simple question: “Why don’t we combine Microwave Chemistry and Electrosynthesis into a one-pot process?” As it turns out, this simple idea led to a much faster way to build compound libraries.  The work resulted in the development of a one-pot sequential microwave electrosynthesis strategy for the …

This research developed a security ink based on gap-enhanced Raman tags (GERTs) that is invisible to the naked eye but detectable through highly specific SERS signals using Raman spectroscopy. The optimized ink produces strong, uniform, and stable Raman signals. By tuning the concentrations of HAuCl4 and HEPES, the researchers balanced SERS enhancement and colloidal stability. …

Researchers have developed an advanced adsorbent derived from sugarcane bagasse-an abundant agricultural waste-by modifying it with magnetic Fe3O4-ZnO nanoparticles and a deep eutectic solvent (DES). The developed material demonstrates high efficiency in removing key water contaminants, including: Diclofenac (pharmaceutical pollutant), Cr(VI) (toxic oxyanion), and Pb(II) (heavy metal). It also exhibits significantly enhanced adsorption capacity compared …
