2+ mon, 2+ week ago  (298+ words) Data center servers, powerful smartphones, and your computer's motherboard have one thing in common. When these devices get too hot, their performance takes a hit, and we can't have that. That's why copper is used to manufacture them: this metal…...

1+ week, 4+ day ago  (261+ words) You know how your fingertip flushes white when you press it against a hard surface? Well, scientists have now used that phenomenon to place augmented reality (AR) touch panels on real-world surfaces such as walls and desks. First of all,…...

3+ week, 2+ hour ago  (549+ words) The heated race to achieve the extreme cold that quantum technologies demand may have a frontrunner. Chinese scientists have developed an alloy that almost reaches absolute zero, the coldest possible temperature, without using the scarce isotope, helium-3. Other examples include…...

1+ mon, 3+ min ago  (409+ words) Researchers have uncovered the mechanical properties of the nanoscale "thorns" that develop inside lithium-ion batteries, which can cause them to short circuit and die " or worse, such as spontaneously catch on fire. These thorns, known as dendrites, have been difficult…...

1+ mon, 5+ day ago  (525+ words) To wood or not to wood, that's been the question! Ever since oil-based plastics burst onto the manufacturing scene, cost, sustainability, and performance have defined the ongoing woods vs. plastics war. In many applications, plastics tend to dominate in cost…...

1+ mon, 1+ week ago  (415+ words) The secret? Our skin and its ability to sweat. A team of researchers from the City University of Hong Kong may have found a way to give batteries this ability, using a Skin-Inspired Adaptive Nanocomposites Cooling Membrane. Taking inspiration from…...

1+ mon, 2+ week ago  (170+ words) Sodium-ion batteries offer multiple advantages over their lithium-ion cousins. Energy storage, however, isn't one of them. That might be set to change thanks to a new method of creating the batteries involving water-rich cathodes. NVOH was so effective in fact,…...

1+ mon, 2+ week ago  (218+ words) At any given moment, 89, 000 terawatts of solar power hits the Earth's surface. While significant advancements have been made in harvesting this power, existing technologies do not capture the full potential of the entire solar spectrum. This limitation primarily lies in…...

2+ mon, 1+ week ago  (314+ words) Scientists have already learned how to make helmets, batteries, and even sports cars from wood, so applying it to something like thermal paper might not sound that exciting. Yet it could actually affect our lives far more than we realize....

2+ mon, 3+ week ago  (285+ words) A team at Germany's Fraunhofer Institute for Ceramic Technologies and Systems (IKTS) has developed a new type of sodium-ion battery that uses lignin as a key electrode material. Lignin is a natural polymer found in trees. It basically acts like…...
