The folds of 3-D graphene make mesopore channels that work with the surface’s micropores to increase the material’s supercapacitive properties.
Two-dimensional materials such as graphene may only be one or two atoms thick but they are poised to power flexible electronics, revolutionise composites and even clean our water.
A collaborative project between Oxford Instrument, the National Physical Laboratory (NPL) and the National Graphene Institute (NGI) at University of Manchester for a turnkey quantum Hall system for graphene characterization and primary resistance metrology has been successfully completed.
Scientists have built a prototype Al-ion battery (AIB) that uses a graphene electrode to intercalate tetrachloroaluminate. The researchers have used the device to investigate the effect of defects and doping on battery performance.
Researchers from Rice University have transformed wood into an electrical conductor by turning its surface into graphene. The team used its LIG technique to blacken a thin film pattern onto a block of pine.
Tata Steel’s first graphene-based product is in the market – the company has announced the launch of ready-made graphene-coated stirrups, named Tiscon Superlinks+.
A new flexible, transparent solar cell made from graphene could transform how solar cells are utilized. Researchers have developed a low cost, organic material with electrodes of graphene that enables the method of depositing a one-atom thick layer of graphene onto a solar cell without damaging nearby sensitive organic materials.
Researchers have developed an ultra-thin, graphene-based device that can be placed in fabrics of clothing to generate electricity from human motion.
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.
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.
