The advanced materials engineering group Versarien announced that it has won a tender for the ongoing supply of nanomaterials to the Centre for Process Innovation. Versarien will supply up to 1.2 kilograms of graphene in a variety of forms to the CPI, in addition to hexagonal layer boron nitride.
Graphene, despite being hailed as a wonder material, has been slow to commericalize. Premature graphene scale-up by groups like Ningbo Morsh Technology and Angstron Materials led to an immense glut that has long outweighed demand. Lux emphasized graphene commercialization hurdles since 2012 and stressed that the materials-push, pursue-every-application approach many companies take is more likely to lead to failure than […]
echnology is only as good as the materials it is made from. Much of the modern information era would not be possible without silicon and Moore’s Law, and electric cars would be much less viable without recent advances in the material science behind lithium-ion batteries. That’s why graphene, a two-dimensional supermaterial made from carbon, is […]
On investigating the electron spin g factor in graphene, Researchers discovered that, this factor is surprisingly insensitive to external effects such as mobility, density and charge carrier type. The g factor is a key parameter that defines the spin properties of electrons in a material, with important implications in spintronic applications.
In this paper, few-layer porous graphene is integrated onto the surface of a metasurface layer to provide a uniform static electric field to efficiently control liquid crystal, thereby enabling flexible metamaterial designs. We demonstrate a tunable cross-shaped metamaterial absorber with different arm lengths driven by this combined metasurface and graphene electrode. The resulting absorber supports […]
Protective corrosion coatings are preferably composed of available, environmentally friendly, and low-volatility organic compounds. Herein, new excellent corrosion graphene/raw lacquer composite coatings were formed, in which waterborne graphene was modified by taking lignin tripolymer (LT) as an aqueous stabilizer and subsequently adding to raw lacquer (RL). Graphene/lacquer composite coatings were achieved by an eco-friendly fabrication […]
Dr. Richard Ordonez, a nanomaterials scientist at the Space and Naval Warfare Systems Center Pacific (SSC Pacific), was having stomach pains last year. So begins the story of the accidental discovery that honey—yes, the bee byproduct—is an effective, non-toxic substitute for the manipulation of the current and voltage characteristics of graphene.
Our world is made up of moving, vibrating and leaping molecules. However, it is not an easy task to capture their movement. IBS Scientists at the Center for Soft and Living Matter, within the Institute for Basic Science (IBS), were able to observe the movement of molecules stored within a graphene pocket without having to […]
The introduction of nanotechnology in the cement industry has a lot of benefits, some of which include reduced emission, improved crack resistance, reduced water absorption, improved strength and ductility.
Graphene assisted dye-sensitized solar cells (DSSCs) have drawn increasing attention because of their high performances. However, two bottlenecks (the high defect density and the discontinuous structure) of the widely adopted reduced graphene oxide (RGO) nanosheets bring about that the practical photovoltaic properties are far inferior to the theoretical prediction values. Therefore, three-dimensional graphene networks (3DGNs) […]
