6+ hour, 3+ min ago  (216+ words) Gold may have a secret self-defense system that helps it resist tarnishing. Researchers discovered that atoms on gold surfaces reorganize themselves into patterns that block oxygen from reacting with the metal, suppressing oxidation by up to a trillion-fold. Beyond explaining…...

1+ day, 20+ hour ago  (341+ words) Now, an interdisciplinary team at the Max Planck Institute for Sustainable Materials (MPI-SusMat) has identified exactly how these dendrites trigger fractures that ultimately lead to battery failure. Their findings were published in the journal Nature. Exactly how soft lithium dendrites…...

3+ day, 58+ min ago  (400+ words) Scientists have rewritten the story of gallium after discovering that its unusual atomic bonds re-form at high temperatures, contradicting decades of accepted theory. The finding changes how researchers explain why the metal melts so easily and behaves unlike almost any…...

4+ day, 9+ hour ago  (421+ words) In most materials, the way heat is absorbed and the way it is emitted are inseparable. If a surface absorbs heat efficiently from a particular direction or wavelength, it also emits heat the same way. This long established principle, known…...

1+ week, 3+ day ago  (753+ words) Water has been studied more than almost any other substance, yet scientists have long debated a surprisingly simple question: What happens to its chemistry when it is squeezed into spaces only a few molecules wide? Those tiny spaces exist throughout…...

2+ week, 4+ day ago  (499+ words) A newly proposed quantum sensing technique could make it much easier to identify one of physics’ newest and most intriguing classes of magnets: altermagnets. These unusual materials, discovered only a few years ago, appear to combine the speed and efficiency…...

3+ week, 5+ day ago  (785+ words) A tightly compressed bundle of office staples can behave in a surprising way. Even though it is made of many separate pieces, the tangled mass can be difficult to pull apart and can act almost like a single solid object....

3+ week, 6+ day ago  (354+ words) Converting carbon dioxide (CO2) into methanol is widely viewed as a promising way to recycle carbon resources. However, scientists have long faced a difficult challenge when trying to improve the process. In a study published in Chem, researchers led by Prof....

1+ mon, 1+ day ago  (865+ words) Limiting long-term global warming to below 1.5°C will require far more than cutting greenhouse gas emissions. According to climate scenarios outlined in the latest Assessment Report from the Intergovernmental Panel on Climate Change (IPCC), the world will also need technologies…...

1+ mon, 3+ day ago  (1033+ words) Chemicals introduced to help repair and protect Earth's ozone layer may have created an unexpected environmental problem. According to a new study, some of the substances that replaced ozone damaging chemicals are now responsible for spreading large amounts of a…...
