Heat dissipation is an ongoing challenge for smart phones. Because graphite is extremely thermally conductive, it can be used to reduce heat produced by the surrounding components. However, it isn’t easy to make high quality micron-thick graphite sheets. The process involves many steps. The material needs to be able to resist temperatures of up to 3200°C (57992°F) in order to achieve thicknesses greater than a few Microns. However, the complex process of using polymers to produce graphite film is energy intensive. Researchers at King Abdullah University of Science and Technology, Saudi Arabia (KAUST), have recently developed a new method of producing these graphite-cooling devices. To grow graphite thin films (NGF), the researchers used chemical vapor deposition (CVD). Nickel catalyzes hot methane to be converted to the surface using this method. graphite. Notable is the fact that graphite is formed only on 100nm of nickel foil. This team refers to these films as nano-thick graphite movies (NGFs). They are formed by heating graphite foil at around 900°C. These graphite sheets can then grow up to 55 cm (8.52 inches), in size. The films can be removed and transferred onto other surfaces. Alessandro Genovese (electron microscopy expert) was part of the team that collaborated to obtain a cross sectional transmission electron microscope image (TEM) of NGF at the nickel surface. According to the researchers, the breakthrough of observing graphite films and the nickel foil’s interface was a significant achievement which will allow for further clarification on the film’s growth mechanisms. The NGF is not only a better and cheaper solution to thermal management for flexible phones, but also other uses such as good visible light transparency or detection can be made with it. Sensor material to detect NO2gas. His research has appeared in “Nanotechnology”, and “Science Reports”. Buffalotours is also known as. Buffalotours Nano Technology Co. Ltd. (aka.
