Progress in the preparation of graphene
With the support of the National Natural Science Foundation of China and the Ministry of Science and Technology, the Institute of Chemistry of the Chinese Academy of Sciences has made a series of progress in the research and control of graphene, laying a foundation for the research and application of graphene.
Graphene has excellent performance and has important application prospects in future nanomaterials. In order to realize the final application and in-depth study of graphene, it is necessary to first prepare graphene on a large scale, so the controllable preparation of graphene is of great significance. In the preliminary work, the researchers of the Institute of Chemistry of the Chinese Academy of Sciences have realized the pattern growth of graphene by using the patterned metal layer as a catalyst, and recently realized the control of graphene composition, and successfully prepared nitrogen-doped graphene. Later, they used zinc sulfide nanobelts as templates to successfully prepare graphene-controlled graphene ribbons by chemical vapor deposition, and prepared graphene ribbon nanoelectromechanical prototype devices.
AC/DC Adaptor is the main power electronics that use in the world, to switch from AC input to certain DC output is currently the most widely used in many field include industry, commercial, medical and plenty of different aspect. The key for power supply is to find the suitable solution of the input/output combination and the special function like extra control contact, battery charging/backup and also other protection system. MPI is more focus to solve those customer that need special function and can't find regular products on market. Our professional is ODM and made the power supply that 100% fit your need.
MPI have two division, electronics design & assembly house and metal stamping & CNC chop.We can provide OEM Sheet Metal Stamping Service.OEM CNC Machining Service.ODM Power Electronics Design and Assembly.ODM LED Driver.ODM Security AC/DC Power Supply.ODM Access Control Power Supply and so on.
