Considered to be a material that is approximately 200 times stronger than steel while also remaining one of the lightest materials on earth, graphene is a two-dimensional hexagonal allotrope of carbon, capable of a wide variety of useful, yet unusual properties.
Associate Professor of Physics, Salvador Barazza-Lopez, from the University of Arkansas, is part of a team that published a review article based on the properties of strained graphene and various other strained two-dimensional atomic materials in the esteemed Reports of Progress in Physics, a review-style journal published by the Institute of Physics in the United Kingdom that has a huge impact factor of 14.3.
The cathode of an electrochemical cell plays an essential role during a process known as a microbial electrosynthesis (MES) driven carbon dioxide reduction reaction. MES is a promising biochemical process which allows for an eco-friendly reduction of carbon dioxide into various carbon-based products.
Formed deep within the earth, graphene has been proved to be stronger than steel, and thinner than a human hair. Some experts even refer to it as “the most amazing and versatile” material known to man.
China has achieved a major breakthrough in heavy-duty anti-corrosion coating by using modified graphene, according to the Chinese Academy of Sciences (CAS).
The results were achieved by scientists led by researcher Wang Liping and academician Xue Qunji through years of research and development.
Transparent electronic and electro-optical (EO) devices have become an area of increasing interest in modern day technology research. Graphene’s excellent optical and electronic properties have made it an ideal material for research in such technologies and has become a material of considerable and continuous interest for transparent conductive electrodes in liquid crystal electro-optical devices.
Recent advances in single-molecule thermoelectricity has isolated and identified different families of high-performance molecules. However, to realize the commercial potential of these molecules and convert them into real-world thin-film energy-harvesting devices, fundamental issues surrounding parallel-aligned junctions within these devices need to be addressed.
Controlling electronic current is essential to modern electronics, as data and signals are transferred by streams of electrons which are controlled at high speed. Demands on transmission speeds are also increasing as technology develops. Scientists from the Chair of Laser Physics and the Chair of Applied Physics at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have succeeded in switching on a current with a desired direction in graphene using a single laser pulse within a femtosecond – a femtosecond corresponds to the millionth part of a billionth of a second. This is more than a thousand times faster compared to the most efficient transistors today.
UK company G2O Water Technologies has signed an agreement with an unnamed consumer products company to test and evaluate its graphene-based water treatment filtration technology.
G2O’s technology works by creating low-cost printed graphene filters or by applying a graphene coating to existing membranes used in water filtration processes.
This allows more water to pass through a membrane and is said to reduce the amount of energy needed to filter the water passing through the membrane by up to 50 percent.
