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.
Researchers at North Carolina State University have created 3D-printed flexible mesh structures that can be controlled with applied magnetic fields while floating on water. The structures can grab small objects and carry water droplets, giving them the potential to be useful as soft robots that mimic creatures living on water surfaces or that can serve as tissue scaffolds for cell cultures.
Many wearable biosensors, data transmitters and similar tech advances for personalized health monitoring have now been 'creatively miniaturized,' says materials chemist Trisha Andrew at the University of Massachusetts Amherst, but they require a lot of energy, and power sources can be bulky and heavy. Now she and her Ph.D. student Linden Allison report that they have developed a fabric that can harvest body heat to power small wearable microelectronics such as activity trackers.
A new, simple, and inexpensive method that uses ultraviolet light to control particle motion and assembly within liquids could improve drug delivery, chemical sensors, and fluid pumps.
A McGill-led international research team provides the first experimental and theoretical proof that it is possible to form strong, stable attractions between some of the heavier elements in the periodic table -- such as arsenic or even antimony. Because hydrogen is not involved in creating the bond between these elements, these new materials should be resistant to water and humidity.
Graphene Flagship researchers reviewed the current research into the safety of graphene and related materials looking at both human health and environmental impact.
Modifications made to perovskite solar cells, or PSCs, render them more stable and scalable than ever before.
The Polymerisation Process research group of the POLYMAT institute of the UPV/EHU-University of the Basque Country has managed to efficiently encapsulate semiconductor nanocrystals or quantum dots of various sizes into polymer particles; great stability in terms of their optical properties and good fluorescence control when combining different quantum dots have been achieved. The possible applicability of these materials as sensors of volatile organic compounds has also been explored.
An international research team led by the University of Liverpool and McMaster University has made a significant breakthrough in the search for new states of matter. In a study published in the journal Nature Physics, researchers show that the perovskite-related metal oxide, TbInO3, exhibits a quantum spin liquid state, a long-sought-after and unusual state of matter.
Graphene exhibits very different properties in humid conditions, according to researchers from Queen Mary University of London.
