A new breakthrough in the use of graphene may lead the textile industry to start producing electronic clothing. Recently, scientists at the University of Manchester have begun to chip away at the central problem of electronic clothing with a new graphene layering technique. The project has compelling results, and it could help fuel the fire for the rise of e-textiles.
With new tape-based sensors attached to the plants, Iowa State University plant scientist Patrick Schnable was able to measure how long it took two kinds of corn plants to move water from roots to upper leaves.
Nanotechnology is an exciting, innovative area promising great benefits to many areas of life, industry and commerce, including construction and the built environment. However there remains concerns about the health impacts from nanotechnologies. We don’t know which materials contain nanoparticles; we don’t know which nanoparticles are present; we don’t know how easily they could become bio-available; and we don’t know what to do if they do become bio-available.
Researchers have demonstrated that a simple sheet of standalone graphene foam can act as efficient solar thermal capture and conversion device. As reported in ACS Nano (“Graphene-Based Standalone Solar Energy Converter for Water Desalination and Purification”), the 3D cross-linked polymer-like graphene material (3DG) material can be used directly in an easy and scalable manner as a clean water generator with high efficiency under normal and even weaker sunlight (down to 0.25 sun).
For the first time, researchers have experimentally observed light emission from individual graphene nanoribbons. They demonstrated that 7-atom-wide nanoribbons emit light at a high intensity that is comparable to bright light-emitting devices made from carbon nanotubes, and that the color can be tuned by adjusting the voltage. The findings may one day lead to the development of bright graphene-based light sources.
In this work, the relative dielectric permittivity of graphene oxide (GO), both its real and imaginary parts, have been measured under various humidity conditions at GHz. It is demonstrated that the relative dielectric permittivity increases with increasing humidity due to water uptake.
