1+ week, 3+ hour ago   (523+ words) Davyne’s near-infrared response can be switched on and off, allowing security markings to appear for inspection and then become invisible again. Researchers in Finland have created a mineral-based material that hides security markings from view but reveals them under infrared…...

1+ week, 3+ hour ago   (523+ words) Nanoscale signals attributed to battery ion movement can actually be false artifacts caused by surface roughness. KAIST researchers discovered that a signal long believed to show ion movement inside batteries is often just an optical illusion caused by rough surfaces....

1+ week, 2+ day ago   (494+ words) What if the material inside a wearable could carry electricity and ions at the same time? The next generation of wearable sensors may not be limited by electronics themselves, but by the materials carrying the current. Scientists need conductors that…...

3+ week, 3+ day ago   (547+ words) These vacancies activate a pre-formed, previously blocked migration pathway for lithium cations, transforming pure LTO into a superior ion conductor. In manufacturing, perfection is usually the goal. A single microscopic flaw can ruin a microchip, crack a structural beam, or…...

3+ week, 3+ day ago   (500+ words) Japan’s Asahi Kasei developed a method that uses lithium carbonate to offset lithium losses in silicon-based batteries. Japan’s Asahi Kasei has developed a battery technology that uses lithium carbonate as an extra lithium source to reduce energy losses in lithium-ion…...

3+ week, 4+ day ago   (551+ words) The structural shift to graphite absorbs collision energy, enhancing the material’s impact resistance. A new manufacturing technique developed at Rice University stabilizes diamond during thermal processing at low pressures, resulting in a dense, resilient composite material. The research, published in…...
