Twisted stacking lets 2D conductor keep single-layer performance in bulk form

Twisted stacking lets 2D conductor keep single-layer performance in bulk form Lisa Lock Scientific Editor Robert Egan Associate Editor Two-dimensional (2D) materials, which are significantly thinner than a single sheet of paper, have long drawn attention for their exceptional performance. However, they have faced a critical limitation: Their performance degrades significantly when multiple layers are stacked. A research team led by Professor Sarah S. Park from the Department of Chemistry at...

Precise polymer 'knots' uncover hidden slack for designing ultra-tough and responsive smart materials

Precise polymer 'knots' uncover hidden slack for designing ultra-tough and responsive smart materials Sadie Harley Scientific Editor Robert Egan Associate Editor From household plastic packaging to the flexible frameworks that support wearable electronics, polymer materials form the invisible backbone of modern life. At a microscopic level, polymers consist of long, ribbon-like molecular chains that are entangled into a disorganized mass resembling a bowl of cooked noodles. For decades,...

Secondary silylium ion drives one-pot ketone sulfonamidation, reaching 95% yields

Secondary silylium ion drives one-pot ketone sulfonamidation, reaching 95% yields Lisa Lock Scientific Editor Andrew Zinin Lead Editor A research team has developed a novel organocatalysis method based on a silylium Lewis acid. This technology employs an ion-pair catalyst combining a diethylsilylium ion with a weakly coordinating anion, enabling the direct installation of sulfonamide groups into functionalized ketone compounds, including β-ketoesters, which had previously been difficult to...

Fast-moving droplets synthesize key drug compounds at room temperature, no catalysts needed

Fast-moving droplets synthesize key drug compounds at room temperature, no catalysts needed Lisa Lock Scientific Editor Robert Egan Associate Editor Chemical reactions are the backbone to nearly all biological processes, including those used to make new medicines. However, these reactions can often take considerable time and require harsh conditions or materials—potentially inhibiting the timely development of life-changing drugs. Purdue University researcher Graham Cooks and his team at...

AI-guided catalyst turns CO₂ and waste into fertilizer at industrially relevant rates

AI-guided catalyst turns CO₂ and waste into fertilizer at industrially relevant rates Sadie Harley Scientific Editor Robert Egan Associate Editor Researchers from the National University of Singapore (NUS) have developed a computation-guided strategy to produce urea more efficiently from carbon dioxide and nitrate. By combining large language models, density functional theory calculations and experiments, the approach identified a cadmium-modified iron oxide catalyst that maintains high urea...

Generation AI: Schools in Asia are embracing artificial intelligence

The schools in Asia embracing artificial intelligence in classrooms Sun 31 May 2026 at 5:12am Anaiya Singhvi loves school, but she often finds chemistry tough going. "It's kind of hard to visualise in real life since it's about molecules and atoms," the Singapore-based secondary school student said. "I've been using AI to help me with that."

Ribosome tunnel interactions reveal how bacteria can pause protein production

Ribosome tunnel interactions reveal how bacteria can pause protein production Lisa Lock Scientific Editor Robert Egan Associate Editor How do bacteria regulate the production of their proteins? Researchers at the University of Hamburg, in collaboration with international partners, have now demonstrated how small protein building blocks, known as peptides, specifically influence bacterial protein production. The findings have been published in two articles in the journal Nature Communications.

'Flawless on the outside, flipped within': Detecting hidden defects in 2D dielectrics with light

'Flawless on the outside, flipped within': Detecting hidden defects in 2D dielectrics with light Gaby Clark Scientific Editor Alexander Pol Deputy Editor A material may appear flawless on the surface yet fail to function properly. The cause lies in structural defects hidden within two-dimensional thin films, which are considered key materials for next-generation semiconductor devices.
