57+ min ago   (904+ words) Researchers from Japan and China have recently made considerable strides in cardiovascular treatments by developing a pioneering type of vascular stent that leverages an innovative manufacturing process known as 4D printing. This new generation of adaptive vascular stents is designed to…...

2+ hour, 55+ min ago   (257+ words) Analyses of 4-billion-year-old minerals reveal active tectonics and crustal recycling in the Hadean, rewriting the planet's infancy. A comprehensive examination of the oldest minerals on the planet, microscopic grains of zircon more resistant than diamond, has provided the strongest chemical…...

3+ hour, 5+ min ago   (485+ words) Atmospheric escape, the process by which a planet loses its atmosphere to space, profoundly influences its evolution, potentially explaining observed patterns like the radius valley and Neptunian desert in exoplanetary demographics. This work details the development of advanced instrumental techniques,…...

3+ hour, 9+ min ago   (413+ words) Scientists have developed a computational method that quantifies and generates 3D maps of steric effects. The technique is more accurate than existing approaches and tests show it works across a wide range of cases, including atropoisomerism, coordination chemistry and organocatalysis enantioselectivity....

5+ hour, 14+ min ago   (374+ words) Dr Graham Melrose was one of Australia's most accomplished chemists and innovators, whose career spanned Johnson & Johnson's No More Tears shampoo to the frontline of antibiotic resistance. Dr Graham John Hamilton Melrose was one of Australia's most accomplished chemists and…...

5+ hour, 18+ min ago   (572+ words) The chemical trifluoroacetic acid (TFA) is a breakdown product of numerous chemicals, including CFC replacement gases used in refrigeration and air conditioning, pharmaceuticals such as gases used in inhalation anaesthesia, pesticides, solvents and other forever chemicals from a class known…...

5+ hour, 22+ min ago   (386+ words) First produced by French chemist Louis Jacques Th'nard in 1818, hydrogen peroxide (H2O2) has many uses. The chemical industry produces over 5 million tonnes of H2O2 per year, for products such as disinfectants, bleaching agents and even rocket fuel. Nearly half of global H2O2 production…...

5+ hour, 42+ min ago   (415+ words) Protonic ceramic cells (PCCs) are emerging as highly efficient devices for power generation, hydrogen production, and chemical synthesis at intermediate temperatures. However, their advancement depends on a deeper understanding of proton transport, hydration mechanisms, and surface catalytic reactions. Infrared Spectroscopy…...

6+ hour, 2+ min ago   (228+ words) The mechanistic detail of the Suzuki reaction is illustrated in Figure 2. The key steps of the reaction are as follows: oxidative addition, transmetallation, and reductive elimination. The reaction occurs in the presence of a base; the role of the base…...

6+ hour, 4+ min ago   (964+ words) LCGC International provides separation science insights, including liquid chromatography (HPLC), gas chromatography (GC), and mass spectrometry (MS). Collaboration between academia and industry has profoundly shaped my professional journey and, more broadly, the evolution of separation science as a discipline. From…...
