2+ hour, 30+ min ago   (355+ words) A team of researchers has built a microphone so small it fits inside a strand of pure silica fiber, yet it can pick up ultrasound far above the limits of human hearing. Because the device is made from glass rather…...

4+ mon, 1+ week ago   (383+ words) Hydride ions (H) have drawn interest as potential charge carriers for future electrochemical devices because of their extremely low mass and high redox potential. Yet, progress has been limited since no electrolyte has been able to provide the combination of rapid…...

4+ mon, 1+ week ago   (508+ words) A new technique stabilizes a metastable form of sodium solid electrolyte, enabling all-solid-state sodium batteries to maintain performance even at subzero temperatures. All-solid-state batteries are considered a safe and powerful option for running electric vehicles, electronics, and even storing energy…...

4+ mon, 1+ week ago   (267+ words) Their experiments focused on monocrystalline diamonds exposed to light pulses lasting just a few attoseconds (a billionth of a billionth of a second). The team employed an advanced method known as attosecond-scale transient reflection spectroscopy to capture these ultrafast processes…...

Scientists have long developed different techniques to produce artificial diamonds, but a new method from researchers, including…...

4+ mon, 4+ week ago   (259+ words) Early Earth lacked life's essentials until a collision with Theia added them. This chance event made life possible. In their study, the Bern researchers demonstrated for the first time that the proto-Earth's chemical makeup was fully established within three million…...

5+ mon, 11+ hour ago   (295+ words) University of Tokyo researchers Shinjiro Takano, Yuya Hamasaki, and Tatsuya Tsukuda have directly imaged how the geometric arrangement of atoms in gold nanoclusters develops at the very earliest stages of growth. Under the same conditions, the team also "grew" an…...

5+ mon, 11+ hour ago   (550+ words) UAlbany chemists created manganese diboride, a high-energy material with potential for rocket fuel and new technologies. Chemists at the University at Albany have developed a high-energy compound that could transform rocket fuel and make space travel more efficient. When ignited,…...

5+ mon, 2+ day ago   (925+ words) Per- and polyfluoroalkyl substances (PFAS) are nicknamed "forever chemicals" in part because their acidity helps them linger in the environment. Many of these toxic chemicals are strongly acidic, so they readily shed protons and take on a negative charge, which…...
