Method to characterize nanoparticle dispersion in graphene-based nanocomposites
University of Manchester researchers, from the i-composite lab, have devised a method to characterize the dispersion of nanoparticles in polymer nanocomposites using non-contact infrared thermography mapping that measures the thermal diffusivity (α) of the graphene nanocomposite and relates α to a dispersion index.
Regulation of two-dimensional nanomaterials for lithium-ion batteries
Li-ion batteries (LIBs) are advantageous energy storage devices due to their higher specific energy density, lower self-discharge, and lower memory effect. Among the components of batteries, electrode materials play a key role in enhancing electrochemical properties. Thus, the development of advanced electrode materials for high-performance LIBs is a major objective in related research fields.
Researchers produce robust graphene-based catalyst to split water into hydrogen and oxygen
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 […]
The Next Big Technology Could Be Nanomaterials
Discoveries surrounding a new class of impossibly small and improbably powerful compounds could reshape the materials industry — and the world around us.
Large single-crystal graphene is possible
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.
Chemical route towards electronic devices in graphene
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.
Color-shifting electronic skin could have wearable tech and prosthetic uses
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.
Turning graphene into gold
Scientists have created a wonder material out of graphite – but the big challenge is how to make a profit from it.
Novel graphene production method relies on degassed water
Researchers have developed a new graphene production technique that uses degassed water, instead of surfactants to prevent graphene flakes from aggregating.
