Researchers have developed a novel core-shell structural catalyst (FeNC@C) for efficient antibiotic degradation that requires no additional energy input. The catalyst achieved 90% degradation efficiency and over 47% total organic carbon removal within 60 minutes, demonstrating significant potential for energy-efficient water treatment and antibiotic decomposition.

India-based researchers from Bharathidasan University and Poland's University of Silesia have developed new eco-friendly ruthenium catalysts for sustainable chemical synthesis. The research demonstrates an environmentally friendly approach to producing bioactive compounds with water and hydrogen as the only byproducts, achieving yields up to 92% using minimal catalyst loading.

Researchers have developed a sustainable electrochemical process for phosphorylation coupling using recyclable triarylamine as a redox mediator. The green protocol demonstrates excellent atom economy, can be conducted under mild conditions without metal catalysts, and has potential applications in drug discovery. The method works with various substrates including functionalized glycine esters, amides and peptides.

China-based researchers from Chongqing University of Technology and Sinopec Lubricant Co. have developed an enhanced water treatment catalyst system using phosphorized magnetic Fe3O4 for removing tetracycline antibiotics from water. The novel P-RC-Fe3O4/PMS system demonstrated high efficiency in degrading tetracycline through both radical and non-radical pathways, with excellent stability and easy magnetic separation capabilities.

Researchers have developed a novel two-electrode system for sustainable chemical synthesis using low-cost electrocatalysts. The system enables direct synthesis of α,β-unsaturated carbonyls in aqueous conditions using minimal energy (1.6V), offering a more environmentally friendly alternative to traditional chemical synthesis methods used in pharmaceuticals, plastics, and lubricants production.

Switzerland-based ETH Zurich researchers have discovered serious side effects of using the molecule AZD7648 in CRISPR-Cas gene editing technology. While the molecule was intended to make gene editing more efficient for developing climate-resilient crops and other applications, researchers found it causes massive genetic alterations and chromosome damage. The study, published in Nature Biotechnology, warns against using this molecule for genome editing until further safety testing is conducted.

Researchers developed stable gold-gold sulfide nanoparticles with different coatings that show strong photoacoustic imaging capabilities in both visible and near-infrared regions, demonstrating potential for biomedical applications.

Researchers developed an acid-responsive singlet oxygen nanodepot (aSOND) that enables controlled release of singlet oxygen for targeted cancer therapy, overcoming limitations of traditional photodynamic therapy.

Researchers have developed a novel antimicrobial dressing using an aggregation-induced emission (AIE)-active photosensitizer called DTTPB combined with Carbomer 940 to create an injectable hydrogel dressing. The innovation addresses antibiotic resistance by effectively killing both Gram-positive and Gram-negative bacteria without promoting resistance, while maintaining biocompatibility with normal cells.
