For many experts, graphene is the material of the future. Its scientific definition can be considered somewhat complex, but the truth is that the properties of this material open a new horizon in the world of technology.Graphene is a material composed of pure carbon, similar to graphite but with characteristics that make it extraordinarily light and strong. A sheet of one square meter of graphene weighs 0.77 milligrams. Its strength is 200 times greater than that of steel and its density …

Lithium-Ion batteries have been a significant invention due to their high energy density. Many researchers are trying to improve lithium-ion batteries since they are used in portable electronic devices and electric vehicles which are required to have long battery life in these days. High energy density, fast rate response, low cost and high safety are the most important parameters for an ideal lithium-ion battery. These parameters are achieved by maximizing the energy density by highcapa …

Just as the heart pumps blood which gives life to humans, likewise batteries pump life into electrical objects or devices. Without batteries, electrical devices cannot function optimally. Basically, a battery is a device that contains one or more electrochemical cells which are dominantly used to power electrical objects such as cars, phones, torchlights, etc.PVDF (Polyvinylidene Fluoride) plays an important role in powering batteries, particularly, the lithium-ion batteries. This is due …

Czochralski Silicon (CzSi) wafer is an important wafer of Silicon. Silicon (Si) is a chemical element which comprises about 30 percent of the earth’s crust. Right after oxygen, it is the commonest natural element in the world and often used in building microchips and semiconductors. Unlike other elements like hydrogen, silicon is not a very good conductor of electricity as a whole. Although, a semiconductor can be built only when silicon has been transformed into liquid or water.Silicon …

As an element, Gallium was first predicted by a Russian scientist named Mendeleev in 1871. According to him, the element should have properties similar to those of aluminum, and should also have an atomic mass of 68 with its formula as Ea203 and gravity, 5.9. These properties later turned out to be very accurate. Also, later on in the century, another French chemist by name Paul Emile Lecoq de Boisbaurdan, who lived between 1838 and 1912, found out after series of research that the metal …
