1. Accelerate the osteogenic differentiation of human bone marrow.Graphene is used to accelerate the osteogenic differentiation of human bone marrow mesenchymal stem cells, and it is also used to make
Graphene battery: Graphene battery is a honeycomb flat film formed by sp2 hybridization of carbon atoms. It is a quasi-two-dimensional material with only one atomic layer thickness, so it is also call
Graphene has outstanding physical, optical and mechanical properties and has been used in transparent touch screens, aerospace and biomedical fields. However, graphene has relatively few uses in the e
In fact, graphene originally exists in nature, but it is difficult to peel off a single-layer structure. Graphene layers are stacked to form graphite, and 1 mm thick graphite contains about 3 million
Graphite paper: High-carbon phosphorus flake graphite is chemically treated and expanded and rolled at high temperature. It is the basic material for manufacturing various graphite seals.The main purp
Graphite has a hexagonal crystal structure. Because the bonding force between the surfaces parallel to the foundation surface is weak, these crystals are easy to shear between the surfaces, that is, t
High-purity graphite refers to the carbon content of graphite>99.99%, which is widely used in advanced refractory materials and coatings in the metallurgical industry, stabilizers of fireworks materia
Discovery and DevelopmentExpandable graphite was first discovered by Schaufautl, a German. In 1841, Schaufautl soaked natural graphite in a mixture of concentrated HNO3 and concentrated H2SO4. After s
There are abundant natural graphite resources in China. Modification of natural graphite for high-energy lithium-ion batteries is one of the effective ways to upgrade China's graphite industry. The hi
Researchers at the Okinawa National University of Science and Technology (OIST) have discovered a special structure called an arched silicon nanocrystalline anode that could overcome a long-standing d
Silicon, among other alternative materials, is expected to be the cathode material for the next generation of high-capacity lithium-ion batteries. The theoretical specific volume of silicon is an orde
Today, electric vehicles are increasingly developing in the direction of high-end intelligence. The R&D and manufacturing technology of electric vehicles is constantly improving, and the production pr
