Exeter researchers have recently reported a new method to use graphene to produce photodetectors, which they feel could revolutionize the manufacturing of vital safety equipment, such as radiation and smoke detection units.
Researchers have studied how light can be used to observe the quantum nature of an electronic material. They captured light in graphene and slowed it down to the speed of the material’s electrons. Then electrons and light started to move in concert, manifesting their quantum nature at such large scale that it could observed with a special type of microscope.
University of Illinois at Chicago scientists have discovered a new chemical method that enables graphene to be incorporated into a wide range of applications while maintaining its ultra-fast electronics.
A group of researchers led by Joseph Friedman of the University of Texas, Dallas, report in Nature Communications development of an all-carbon spintronic system in which spintronic switches function as gates.
An international team of researchers, led by the University of Bern and the National Physical Laboratory (NPL) and assisted by the University of the Basque Country (UPV/EHU, Spain) and Chuo University (Japan), has demonstrated a new way to control the functionality of next-gen molecular electronic devices using graphene.
Recently, solar steam and vapor generation has attracted attention as a promising prospect in desalination, sterilization and chemical purification. Tremendous progress has been achieved in absorber designs and thermal management. However, in all the previous designs, because of the minimized optical loss and heat conduction loss, losses related to convection and conduction start to dominate. Therefore, it becomes critical to simultaneously minimize the losses related to radiation, convection and conduction simultaneously in order to achieve optimum solar steam performance and enable widespread applications.
An international team of scientists collaborating in the Graphene Flagship project has developed a graphene-based transistor that reportedly outperforms previous state-of-the-art ones.
Graphene-based transistors enable a flexible neural probe with excellent signal-to-noise ratio. Such probes are useful for examining neural activity for understanding diseases, as well as in neuroprosthetics for control of artificial limbs.
Currently, most parts of a smart phone are made of silicon and other compounds, which are expensive and break easily, but with almost 1.5 billion smart phones purchased worldwide last year, manufacturers are on the lookout for something more durable and less costly.
Dr Elton Santos from Queen’s University’s School of Mathematics and Physics, has been working with a team of top-notch scientists from Stanford University, University of California, California State University and the National Institute for Materials Science in Japan, to create new dynamic hybrid devices that are able to conduct electricity at unprecedented speeds and are light, durable and easy to manufacture in large scale semiconductor plants.
