Scientists have developed a catalyst that can simplify the splitting of water into hydrogen and oxygen to produce clean energy. The electrolytic film is a three-layer structure of nickel, graphene and a compound of iron, manganese and phosphorus. The foamy nickel gives the film a large surface, the conductive graphene protects the nickel from degrading and the metal phosphide carries out the reaction.
Discoveries surrounding a new class of impossibly small and improbably powerful compounds could reshape the materials industry — and the world around us.
Researchers reported the synthesis of a large sheet of monolayer single-crystal graphene. This result allows a leap forward in graphene production to an optimized method of fabricating an almost-perfect (> 99.9 % aligned) 5 × 50 cm2 single-crystal graphene in just 20 minutes.
The use of graphene in electronic devices requires a band gap, which can be achieved by creating nanostructures such as graphene nanoribbons. A wide variety of atomically precise graphene nanoribbons can be prepared through on-surface synthesis, bringing the concept of graphene nanoribbon electronics closer to reality.
A study from Tsinghua University in Beijing, employed flexible electronics made from graphene, in the form of a highly-sensitive resistive strain sensor, combined with a stretchable organic electrochromic device.
Scientists have created a wonder material out of graphite – but the big challenge is how to make a profit from it.
Researchers have developed a new graphene production technique that uses degassed water, instead of surfactants to prevent graphene flakes from aggregating.
Researchers show a graphene plasmonic phase modulator that is capable of tuning the phase between 0 and 2π in situ.
Graphene currently is the most studied material on the planet – this is especially true for charge storage and the results from many laboratories confirm its potential to change today’s energy-storage landscape. Specifically, graphene could present several new features for energy-storage devices, such as smaller capacitors, completely flexible and even rollable energy-storage devices, transparent batteries, and high-capacity and fast-charging devices.
Nanoparticle dispersion is widely recognised as a challenge in polymer nanocomposites fabrication.
The dispersion quality can affect the physical and thermomechanical properties of the material system.
Qualitative transmission electronic microscopy, often cumbersome, remains as the ‘gold standard’ for
dispersion characterisation. However, quantifying dispersion at macroscopic level remains a difficult
task.
