Graphene, a honeycomb sheet of carbon atoms just one atom thick, was first isolated in 2004 with adhesive tape and a lump of graphite, work that earned a Nobel Prize in 2010. Large sheets of graphene conduct electricity superbly, but they are not magnetic. Shrink a piece to a few nanometres, however, and its boundary […]
Lithium and sodium are neighbours in the periodic table. Both are alkali metals, both have a single electron in their outer shell, and both can be used to shuttle ions between two electrodes to store and release electrical energy. At first sight, replacing lithium with sodium in a rechargeable battery might therefore seem straightforward. There […]
Scientists have discovered a class of metal that can unexpectedly resist extreme cold using an unusual mechanism. Normally such temperatures would make similar materials brittle and vulnerable to breaking. The findings point to new principles for designing materials for cryogenic environments. An international team led by University of California, Berkeley, Lawrence Berkeley National Laboratory and […]

In 2004, physicists isolated graphene, a sheet of carbon just one atom thick. It launched the study of two-dimensional (2D) materials: crystals a few atoms thick in which electrons are confined to a plane and can behave quite differently from those in ordinary solids. The family of known and predicted 2D crystals has since grown […]
Scientists have developed remarkably long, precisely patterned molecular threads that could open new possibilities for designing advanced materials. The scientists also discovered these threads — called supramolecular polymers — can dramatically enhance brain cell activity. Built from self-assembling molecules, the longest threads reach dimensions greater than the diameter of a cell. By molecular standards, they […]
In 1911, Heike Kamerlingh Onnes cooled mercury to a few degrees above absolute zero and watched its electrical resistance vanish. Lead soon joined the list of superconductors, losing its resistance below about 7.2 kelvin. A full explanation arrived in 1957: electrons bind into Cooper pairs that move together as one collective state below a critical […]
When light or sound bounces around inside an oddly shaped room, its reflections can quickly become difficult to predict. But new research led by scientists at the Advanced Science Research Center at the CUNY Graduate Center (CUNY ASRC) shows that waves can behave very differently when they travel through a special class of materials. The […]
26 April 2026 will always be remembered as the day an apparently impossible barrier was finally broken. At the London Marathon, Kenya’s Sabastian Sawe and Ethiopia’s Yomif Kejelcha became the first men to officially run the 42.195 km distance in under two hours, finishing in 1:59:30 and 1:59:41 respectively. Reaching this landmark was not the […]

Nickel disulfide, NiS₂, is an unusual material. Its interior behaves as an electrical insulator, blocking the flow of current, while certain parts of its surface conduct electricity freely. This contradiction has puzzled physicists for decades, and a recent study offers a detailed explanation. The conduction, it turns out, is confined to tiny one-dimensional steps on […]
Researchers at Nagoya University have built a graphene nanoribbon that can switch which way it twists using a natural solvent. Graphene nanoribbons are thin ribbon-shaped structures made of fused carbon rings. Twisted or helical versions of these ribbons show promise for advanced light and electronic devices. However, no graphene nanoribbon could switch that twist on […]
