The use of graphene to batteries Graphene is a very versatile molecule found in many different uses, including batteries. It has unique properties, such as high conductivity, outstanding mechanical properties, and amazing electrochemical features. I…
Production of graphene powder Graphene is a single-atom thick sheet of carbon that is extremely durable. Its hexagonally-connected carbon atoms provide it with strength and a very thin, lightweight form. This material is becoming the preferred choice…
Graphene is a two-dimensional crystal, which consists of carbon atoms with sp2 hybrid orbitals to form two-dimensional carbon nanomaterials with hexagonal honeycomb lattice.…
Although hydrogen fuel is a promising alternative to fossil fuels, the catalyst it relies on for power generation is mainly composed of rare and expensive metal platinum, which limits the wide commercialization of hydrogen fuel.…
Few layer graphene is a new two-dimensional carbon material with atomic thickness. It can be used as lithium battery anode material.…
Graphene oxide is an oxide formed by the oxidation of graphite by strong acid. It adopts the oxidation reaction of potassium permanganate in concentrated sulfuric acid and graphite powder to obtain a tan edge derivative carboxylic acid base and pheno…
U.S. refiners forecast strong first-quarter earnings as margins on gasoline and diesel sales improved, refining capacity fell sharply and crude supplies tightened due to the Russia-Ukraine war.Global refining capacity has declined amid the coronaviru…
