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.
Just 13 years since graphene was first isolated, it’s being added to everything from tennis rackets to million-dollar watches.
- By introducing defects into the perfect surface of graphene on silicon carbide, researchers have increased the capacity of the material to store electrical charge. This result increases our knowledge of how this ultrathin material can be used.
Creating a bulge in a graphene sheet offers the first measurement of the shear forces between graphene layers, an essential factor in many graphene-based devices.
A research team has developed a technology that can control graphene electronic device through static electricity. The team has developed a gate that utilizes the graphene electrostatic phenomenon; Static electricity that occurs from friction is trapped inside of a lower board and serves as a gate.
Researchers have demonstrated here a transfer printing method based on a hydrophobic mold suitable for high-resolution patterning of graphene inks.
An international team of researchers have found a new way to tune the functionality of next-generation electronic devices – using graphene electrodes.
A group of researchers has developed a graphene-bacterial cellulose nanofiber (GC/BCN) hybrid sensor to detect alcohol (ethanol) with great efficiency. The sensor was described as flexible, transparent, highly sensitive and with an excellent alcohol recognition performance. Electrical tests in different liquid environments were performed, with remarkable results.
