Chemical vapor deposition (CVD) is the most common way of producing graphene and is performed in many ways throughout the world. Growing graphene directly into electronic devices is a highly desirable process, but has been difficult to perform due to high process temperatures (of around 1000 °C) damaging the substrate components.
Could graphene be the answer to replacing conflict minerals in the electronics supply chain? writes Richard Wilson, consultant editor Electronics Weekly.
Scientists have developed highly efficient battery anodes using graphene and asphalt. To achieve this, the researchers mixed asphalt with conductive graphene nanoribbons and coated the compositewith lithium metal through electrochemical deposition. The anodes showed exceptional stability after more than 500 charge-discharge cycles. A high-current density of 20 milliamps per square centimeter demonstrated the material’s promise for use in rapid charge and discharge devices that require high-power density.
The facility will also be used to experiment with new technologies, including graphene, 3D printing and nanocomposites, which Surface Generation believes have the potential to significantly improve the cost, quality and throughput of high-volume composite component manufacturing.
Graphene is a sheet of carbon that is only one atom thick, and it has drawn worldwide attention as a new material. A research group from Kumamoto University, Japan has discovered that pressure can be generated by simply stacking graphene oxide nanosheets, a material that closely resembles graphene. They also found that the pressure can be increased by reducing the interlayer distance through heat treatment. It is an innovative approach for applying high pressure without using an enormous amount of energy.
Focus Graphite, the Canada-based advanced exploration and mining company, recently announced a first closing of a non-brokered private placement at which it has gathered proceeds of $75,000.
Saint Jean Carbon, a carbon science company engaged in the design and development of carbon materials and their applications, has announced its intention to complete a non-brokered private placement financing of up to $500,000. The Company intends to use the proceeds of the Offering for general corporate and administrative purposes.
The world of graphene is a fast evolving place but just what is all this activity about? Looking at patents filed is one way, and the most recent analysis of worldwide patents found that there were 25,855 individual patent publications that involve graphene. But this is not the full story, read on to find out more…
Graphene, not glass, is the key to better optics, reports Lydia Hales. A lens just a billionth of a metre thick could transform phone cameras. Researchers at Swinburne University in Melbourne, Australia, have created ultra-thin lenses that cap an optical fibre, and can produce images with the quality and sharpness of much larger glass lenses.
