Decade-long experiment produces yet another conflicting value for the gravitational constant
16+ hour, 32+ min ago (520+ words) Confusion continues in the physics community over the precise value of the gravitational constant (G), a fundamental constant that determines the gravitational force between objects in the universe. A research team led by Stephan Schlamminger at the U. S. National Institute of Standards…...
Automated system tracks water flea heartbeats to detect trace water pollutants
5+ day, 12+ hour ago (300+ words) A technology has been developed to automatically and simultaneously measure the heartbeats of 150 water fleas, which are widely used in aquatic environmental toxicity assessments. It is expected to contribute to more precise evaluations of toxicity from low-concentration pollutants and the…...
Atomic clocks may reveal time existing in two states at once
5+ day, 18+ hour ago (159+ words) Physicists have suggested the possibility of experimentally confirming the phenomenon of time's flow existing in multiple states simultaneously using atomic clocks. The research team posited that if a clock's movement follows quantum mechanics, the flow of time it records could…...
Novel protective layer makes magnesium batteries stable in ambient air
2+ week, 3+ day ago (215+ words) A technology has been developed to overcome the vulnerability to moisture, the main weakness of magnesium batteries, which are considered a next-generation alternative to lithium batteries." Magnesium is abundant in seawater and the Earth's crust, inexpensive, and chemically more stable…...
Dual-layer membrane removes over 99% of 'forever chemicals' from water
2+ week, 5+ day ago (228+ words) Short-chain PFAS, having fewer carbon atoms, are small, light, and highly soluble in water. They do not concentrate at a specific point and can pass through the membrane with water, making them difficult to remove. Long-chain PFAS are not soluble…...
[Sci-Tech NOW] New catalyst utilizes platinum's interior to boost hydrogen production
2+ week, 5+ day ago (240+ words) The Gwangju Institute of Science and Technology (GIST) announced on the 7th that a research team led by Professor Myunghwan Yoon of the School of Materials Science and Engineering has developed a next-generation catalyst technology. This technology uses a conductive polymer…...
[Sci-Tech NOW] New milling process turns solar panel waste into high-purity hydrogen.
2+ week, 5+ day ago (337+ words) Ulsan National Institute of Science and Technology (UNIST) announced on the 6th that a team led by Professor Jong-Beom Baek of the Department of Energy and Chemical Engineering has developed a high-efficiency method to simultaneously produce high-purity hydrogen and high-value-added industrial…...
Liquid metal particles create highly stretchable, anti-freezing hydrogel electrolyte
2+ week, 6+ day ago (291+ words) A South Korean research team has developed an ultra-stretchable electrolyte material that can be stretched to nine times its original length at -20 C without any performance loss. This development is expected to enable energy storage devices that operate reliably in…...
Scientists cool a nanoparticle's rotation to its quantum ground state
2+ week, 6+ day ago (384+ words) Scientists have successfully controlled and measured the rotational motion of an object at cryogenic temperatures near absolute zero. The findings are expected to pave the way for ultra-sensitive quantum sensors capable of detecting minuscule torques and for testing various physical…...
[Sci-Tech NOW] Novel Cobalt-Iron Catalyst Maintains Stability at High Temperatures
3+ week, 4+ day ago (293+ words) A POSTECH research team led by Professor Ahn Ji-hwan of the Department of Mechanical Engineering, in collaboration with China's Nanjing University of Information Science and Technology, UNIST (Ulsan National Institute of Science and Technology), and Seoul National University, announced on…...
