Silicon semiconductors used in existing photodetectors have low light responsivity, and the two-dimensional semiconductor MoS₂ (molybdenum disulfide) is so thin that doping processes to control its electrical properties are difficult, limiting the realization of high-performance […]
3D printing is a simple way to create custom tools, replacement pieces and other helpful objects, but it is also being used to create untraceable firearms, such as ghost guns, like the one implicated in […]
A new ultra-thin, transparent film, developed by researchers at UNIST can generate electrical signals solely through mechanical peeling or pressing actions. This technology paves the way for smart sensors that operate without batteries, with potential […]
From electric cars to artificial intelligence (AI) data centers, the technologies people use every day require a growing need for electricity. In theory, nuclear fusion—a process that fuses atoms together, releasing heat to turn generators—could […]
Lithium metal (Li-metal) batteries are among the most promising alternatives to widely employed rechargeable lithium-ion (Li-ion) batteries, as they could store more energy and thus extend the battery life of many electronic devices. Despite their […]
When we are out in cold weather, we wear warm clothes to stay comfortable. But there is a snag. Regular warm clothing can’t adjust to changes in our body temperature. If we start to sweat, […]
Swiss pilot Raphael Domjan beat the altitude record for a solar-powered electric plane in a flight that took him soaring to 9,521 meters, his team announced Wednesday.This post was originally published on this site
Animals like bats, whales and insects have long used acoustic signals for communication and navigation. Now, an international team of scientists has taken a page from nature’s playbook to model micro-sized robots that use sound […]
Advances in technology have led to the miniaturization of many mechanical, electronic, chemical and biomedical products, and with that, an evolution in the way these tiny components and parts are transported is necessary to follow. […]
Delivery drones are so fast they can zip a pint of ice cream to a customer’s driveway before it melts.This post was originally published on this site
