4+ hour, 7+ min ago   (530+ words) The number of antennas on a router dictates the number of signals that router can put out. More signals means wider reach and more devices with connection. Why do routers have so many antennas? How many you need depends on…...

6+ hour, 18+ min ago   (628+ words) Semiconductors are the beating heart of modern technology, yet the organic varieties that promise flexible, lightweight and cheap alternatives to silicon have long been haunted by an inconvenient paradox. To conduct electricity, many organic frameworks need to be treated with…...

10+ hour, 24+ min ago   (55+ words) Every smartphone, wearable sensor, and implanted medical device now competes in a world saturated with radio waves, and the electromagnetic noise that connects our gadgets also threatens to scramble them. Engineers have long sought shielding materials that are thin, light,…...

11+ hour, 37+ min ago   (675+ words) Power electronics rarely make headlines, yet nearly every watt that flows through an electric vehicle, a solar farm, a data center, or a fast charger passes through a semiconductor switch that must block high voltages, carry heavy currents, and waste…...

12+ hour, 5+ min ago   (623+ words) Lithium-sulfur batteries have spent decades promising an energy-storage revolution that never quite arrived. On paper, the chemistry is extraordinary: sulfur is abundant, cheap, and capable in principle of storing several times more energy per kilogram than the intercalation cathodes used…...

12+ hour, 21+ min ago   (614+ words) Direct ink writing, a nozzle-based extrusion technique that squeezes concentrated ceramic pastes into self-supporting three-dimensional structures, has matured from a laboratory curiosity into one of the most versatile platforms for manufacturing high-performance ceramic components....

18+ hour, 17+ min ago   (148+ words) Two PaperCut vulnerabilities are now chained into a fully automated attack pipeline with in-memory persistence—and 47% of installations can't patch. On August 26, security researchers at Huntress identified anomalous activity in customer logs involving base64-encoded commands like whoami and tasklist. This…...

21+ hour, 46+ min ago   (165+ words) This study proposes an efficient trajectory planning method for fixed-wing unmanned aerial vehicles (UAVs) based on an improved A*-guided initialization strategy for complex obstacle environments. An improved three-dimensional A* method is developed to generate smooth and collision-free global paths…...
