Researchers at the University of Bristol have successfully demonstrated the high thermal conductivity of a new material, paving the way for safer and more efficient electronic devices -- including mobile phones, radars and even electric cars.
A team of researchers led by scientists from the Max Born Institute for Nonlinear Optics and Short Pulse Spectroscopy (MBI) in Berlin has now been able to follow the flow of angular momentum during ultrafast optical demagnetization in a ferrimagnetic iron-gadolinium alloy in great detail, in order to understand the fundamental processes and their speed limits. The results were published in Physical Review Letters.
Through a mechanism known as the Spin Hall effect, it has been shown that a voltage can be generated by harnessing differences in spin populations on a metal contact attached to a ferromagnetic material. Researchers from The University of Texas Permian Basin used supercomputers at the Texas Advanced Computing Center to identify various forms of cobalt oxide combined with nickel and zinc that show promise for thermoelectric generation by taking advance of the Spin Hall effect.
ORNL story tips: Using ORNL's Summit supercomputer, scientists created some of the largest virtual universes; plant-based, super-sticky material proves stickier than mussels; method to 3D print big components with metal could promise low-cost, high-quality builds with less waste; simulated small modular reactors on Summit ran more efficiently than expected.
Many people fondly remember playing with toys known as Shrinky Dinks® -- sheets of polystyrene plastic with shapes that kids can color, cut out and heat in an oven, where they shrink into thicker pieces of plastic. Now, researchers have repurposed shrink films for an unexpected use: making strong, durable grippers that could someday encapsulate materials or be incorporated into soft robotics. They report their results in ACS Applied Polymer Materials.
Prehistoric Iberians created 'imitation amber' by repeatedly coating bead cores with tree resins, according to a study published May 1, 2019, in the open-access journal PLOS ONE by Carlos Odriozola from Universidad de Sevilla, Spain, and colleagues.
Northwestern University researchers have developed an algorithm that makes it possible to design glassy materials with dynamic properties and predict their continually changing behaviors.
The oxygen evolution reaction (OER) is of great significance in energy-related techniques, such as metal-air batteries and water splitting. Chinese scientists have doped site-defined sp-N and S atoms into graphdiyne, which enables highly active catalysis of OER.
A University of Cordoba research project is able to incorporate luminescence into this super material, paving a new way to continue expanding properties.
