- Heat transport through pillared graphene could be made faster by manipulating the junctions between sheets of graphene and the nanotubes that connect them, according to researchers.
A new sensor might improve water quality and ultimately better ensure that the water that enters homes and businesses is contaminant free.
Researchers from the University of Wisconsin-Milwaukee have developed a graphene-based sensing platform that can detect various water contaminants including heavy metals bacteria, nitrates and phosphates in real-time.
Nerves and their connections are the wiring in our bodies that connect brain to muscles. When this goes wrong we can end up paralysed and permanently incapacitated. So when I heard that a team in South Korea found that graphene oxide could help nerves reconnect I thought you might like to know too…
Peter Steeneken (professor) and Farbod Alijani (assistant professor) from the Dynamics of Micro and Nanosystems Section at the Department of Precision and Microsystems Engineering have developed a new method to determine the material properties of graphene with the aid of high-frequency non-linear dynamics. Their new method makes it possible to accurately measure the Young’s modulus (elastic modulus) of graphene and enables a potentially quicker measurement. This could make it easier to characterise a large number of membranes in a production process, for example. This week, Peter and Farbod published their article entitled ‘Nonlinear dynamic characterization of two-dimensional materials’ in Nature Communications.
Desalination of seawater remains one of the most challenging and expensive ways to produce drinking water. But as water scarcity forces communities in many parts of the world to find new sources of drinking water, our international research team based in The University of Manchester is committed to making a breakthrough in this critical field using our world-leading expertise in materials science.
The ability of graphene to add functionality to common objects has been exploited in a new product on the market: footwear with better thermal properties. Developed by Graphene Flagship partners Istituto Italiano di Tecnologia, Italy, in collaboration with FADEL, a leading Italian shoe company based in Tuscany, the new GET® technology, patented by FADEL, gives the footwear better thermoregulation and freshness.
The combination of graphene with quantum dots for use in optoelectronics stems in large part from the contributions of Gerasimos Konstantatos, a group leader at ICFO, who worked with Ted Sargent at the University of Toronto, whose research group has been at the forefront of exploiting colloidal quantum dots for use in a range of applications, most notably high-efficiency photovoltaics.
U.S-based Urbix Resources has unveiled new high-density, low leakage graphene-based supercapacitors. According to Urbix, these supercapacitors have energy density of >75 wH/L with volumetric discharge energy density that is five times larger than average, with the lowest leakage rate in market (<1μA/day over 30 days) and operational temperatures that go from -40° C to 70°C.
Transparent electronic and electro-optical (EO) devices have become an area of increasing interest in modern day technology research. Graphene’s excellent optical and electronic properties have made it an ideal material for research in such technologies and has become a material of considerable and continuous interest for transparent conductive electrodes in liquid crystal electro-optical devices.
