A Graphene-MoS2 combination could assist in efficient splitting of water to create 'green' energy

Jul 10, 2017

Researchers from Florida State University, Penn State University, Tsinghua University in China and the Institute of Carbon Science and Technology in Japan have come to fascinating conclusions on how to produce pure hydrogen, a green energy fuel by splitting water.

After experimenting with ways to use the compound molybdenum disulfide to split water, the team realized that the compound’s protons did not overlap well with that of hydrogen. They ultimately determined that the best way to split the hydrogen was to create an alloy with the molybdenum disulfide. They created a thin film with alternating graphene and tungsten-molybdenum layers.

Manipulating electron spin in graphene may enable ambient-temperature FETs

Jul 09, 2017

Researchers at Chalmers University, affiliated with the Graphene Flagship, have devised a graphene-based spin field-effect transistor with the ability to function at room temperature. The team used the spin of electrons in graphene and similar layered material heterostructures to fabricate working devices in a step towards combining memory devices and the logic of spintronics.

The researchers demonstrated that the spin characteristics of graphene can be electrically regulated in a controlled way, even at an ambient temperature. In addition to possibly unlocking various probabilities in spin logic operations, this study also enables integration with magnetic memory elements in a device unit. If further advancements can assist in the production of a spin current without the need for charge flow, the amount of power needed will be considerably reduced, resulting in highly versatile devices.

Researchers design a spray-on sensing technology that detects structural integrity

Jul 09, 2017

A team of researchers from Hong Kong Polytechnic University (PolyU) has developed sensors which can be sprayed directly onto flat or curved surfaces. The sensors, made from a hybrid of carbon black (CB), graphene, other conductive nano-scale particles, and polyvinylidene fluoride (PVDF), can be networked to extract rich real-time information on the health status of the structure being monitored.

The technology includes a sensor network with a number of the sprayed nanocomposite sensors and an ultrasound actuator to actively detect the health condition of the structure to which they are fixed. When the ultrasound actuator emits guided ultrasonic waves (GUWs), the sensors will receive and measure the waves. If damage is detected, such as a crack in the structure, propagation of GUWs will be interfered by the damage, leading to the wave scattering phenomena to be captured by the sensor network. The damage can then be characterised quantitatively and accurately.

Graphene Flagship research teams prepare to test graphene's potential for aerospace applications

Jul 08, 2017

The Graphene Flagship has announced preparations for two new experiments in collaboration with the European Space Agency (ESA), to test the viability of graphene for space applications. Both experiments will launch between 6-17th November 2017, testing graphene in zero-gravity conditions to determine its potential in space applications.

One of the two experiments (named GrapheneX) will be fully student-led, by a team of Graphene Flagship graduate students from Delft Technical University in the Netherlands. The team will use microgravity conditions in the ZARM Drop Tower (Bremen, Germany) to test graphene for light sails. By shining laser light on suspended graphene-membranes from Flagship partner Graphenea, the experiment will test how much thrust can be generated, which could lead to a new way of propelling satellites in space using light from lasers or the sun.

Applied Graphene Materials partners with HMG Paints to commercialize graphene coatings

Jul 06, 2017

Applied Graphene Materials logoApplied Graphene Materials has partnered with HMG Paints to develop and commercialize grahene-containing coatings for a variety of industries. Following an initial stage of controlled environment testing, which reportedly produced positive results, the two companies are now testing their product in a real world environment.

Tests will focus on the application of graphene-based coatings in both the commercial Vehicle and construction Equipment markets in partnership with a leading UK commercial vehicle body builder.
