For the first time, the number of #graphene patents exceeded #nanotubes in 2021! Carbon nanotubes always had the highest number of patents among different #nanomaterials in previous years. The third place belongs to #quantum_dots.
A new #standard about the methodology for measuring the thickness of #graphene_oxide (GO) flakes using SEM and AFM is under development. It is applicable to the characterization of graphene oxide in powder and liquid dispersion forms.
The ISO #nanotechnology_standard (ISO/TS 21356-1) specifies the sequence of methods for characterizing the structural properties of #graphene including the number of layers, thickness, the lateral flake size, the level of disorder, and the specific surface area.
Newly developed #graphene_oxide based #sensor platform can rapidly detect sepsis or the antibodies against the #coronavirus, also open the door to further applications including the detection of harmful gases such as carbon monoxide at room temperature.
Laser-induced #graphene that can conduct electrical charge to kill the trapped #microorganisms in the mask filter, is effective in blocking out 99 percent of particles over 0.3 micrometers and 80 percent of smaller particles.
According to the Annual Report 2018 of #GRAPHENE_FLAGSHIP, the achievements are 145 partners, 31 partnering projects, 46 launched products, 9 spin-off companies, 25 granted patents, and 80+ promising application areas analyzed.
#Highways_England is looking to avert deterioration in roads by investigating the use of #graphene in surfaces. Adding graphene into maintenance operations has the potential to extend asset life and make the network perform at an industry-changing level.
