Graphene ribbons that are only a few atoms wide, so-called graphene nanoribbons, have special electrical properties that make them promising candidates for the nanoelectronics of the future: While graphene – a one atom thin, honeycomb-shaped carbon layer – is a conductive material, it can become a semiconductor in the form of nanoribbons. This means that […]
Graphene’s unique combination of electrical and physical properties marks it out as a potential candidate for transparent, stretchable electronics, which could enable a new generation of sophisticated displays, wearable health monitors, or soft robotic devices. But, although graphene is atomically thin, highly transparent, conductive, and more stretchable than conventional indium tin oxide electrodes, it still […]
Using a pierced gold sheet coated in graphene, scientists have created thin lenses that can be used to manipulate the intensity and polarity of light. Scientists in South Korea and the United Kingdom have developed optical devices made of graphene and gold which can control the intensity and polarity of light. They published their findings in […]
Electronics makers seem determined to connect more and more objects to the internet. But if they’re going to cover urban infrastructure, the environment, and even our bodies with electronic sensors, they also need to think about the expense and environmental impacts of these devices, says Deji Akinwande, an electrical engineer at the University of Texas, […]
Lower production costs are boosting the use of nanomaterials in packaging and textiles. Nanominerals can improve food conservation while nanocoatings block microbial contamination of textiles. Exploiting the full potential of nanotechnology, however, remains a key challenge.
A University of Manchester partnership is launching a revolutionary world-first in the sports footwear market following a unique collaboration with graphene experts. British sportswear brand inov-8 has teamed up with The University of Manchester to become the first-ever company to incorporate graphene into running and fitness shoes.
Researchers at the University of Washington have published a paper on 3D printed wireless sensors capable of operating not only without batteries but without electronics of any kind, yet still capable of providing useful data to nearby Wi-Fi-based receivers.
ICN2 researchers have demonstrated that the application of a thermal gradient in spintronic devices can cause spin signal to increase as a result of a novel thermoelectric phenomenon predicted and subsequently observed in graphene. Specifically, the enhanced spin signal is two orders of magnitude larger than anything previously reported for thermal effects in metals. Published in Nature […]
Experimentalists of the ICN2 Physics and Engineering of Nanodevices Group, led by ICREA Prof. Sergio O. Valenzuela, have found evidence that the spin-orbit coupling induced in graphene by proximity to transition metal dichalcogenides affects electron spins differently depending on their orientation. Published in Nature Physics, this work suggests new approaches to controlling the transport of […]
In this study, the authors report a novel strategy to prepare graphene nanopapers from direct vacuum filtration. Instead of the conventional method, i.e., thermal annealing nanopapers at extremely high temperatures prepared from graphene oxide (GO) or partially reduced GO, they fabricate our graphene nanopapers directly from suspensions of fully reduced graphene oxide (RGO), obtained after […]
