Scientists at the US Department of Energy's Ames Laboratory have discovered the relaxation dynamics of a zero-field state in skyrmions, a spinning magnetic phenomenon that has potential applications in data storage and spintronic devices.
Graphene Flagship researchers reviewed the current research into the safety of graphene and related materials looking at both human health and environmental impact.
Scientists of the Far Eastern Federal University, together with Russian and foreign colleagues, developed samples of nickel mesoporous film structures, which have useful surface area up to 400 times greater than their solid one. Brand new material can be used in energy saving, chemical industry and other practical areas. The research results are published in Applied Surface Science journal.
Using a new computational method, an international collaboration has succeeded for the first time in systematically investigating magnetic quantum effects in the well-known 3D pyrochlore Heisenberg model. The surprising finding: physical quantum phases are formed only for small spin values.
New printing technique and materials could be used to develop intelligent materials and self-adaptive infrastructures and transducers.
Researchers from Osaka University, in collaboration with the National Institute of Advanced Industrial Science and Technology (AIST) and Grenoble Alpes University, succeeded in efficiently controlling the direction of a nano-sized magnet by heating at high speed. The researchers also discovered that nano-magnets amplify microwave signals. These achievements will contribute to reducing power consumption for magnetoresistive random access memory and artificial intelligence devices, helping us move towards a super-smart society.
A recent study, affiliated with South Korea's Ulsan National Institute of Science and Technology (UNIST) has proposed a novel technique that can reduce the congestion issues in the network environment.
Now, researchers at the University of Missouri have discovered spin flips happen in one half of one trillionth of a second, or half a picosecond in the course of a chemical reaction. To understand how fast it is -- watches count in seconds, sporting games are timed in 10ths of a second, and light travels just under 12 inches in one-billionth of a second. Spin flips are faster.
Experimental proof of a decades-old prediction opens a pathway to recreate possible conditions of the early universe here on earth.
A new, more sensitive method to measure ultrasound may revolutionize everything from medical devices to unmanned vehicles. Researchers at The University of Queensland have combined modern nanofabrication and nanophotonics techniques to build the ultra precise ultrasound sensors on a silicon chip.
