  • Patent number: 10947120
    Abstract: A production method of low dimensional nano-material comprises steps of: introducing a layered material; adding an intercalating agent into the layered material; and exfoliating the layered material by ball-milling to form the low dimensional material. Mechanochemical approaches for low dimensional nano-material like graphene quantum dots synthesis offer a promise of new reaction pathways, and greener and more efficient syntheses, making them potential approaches for low cost production.

  • Publication number: 20210062427
    Abstract: Present invention is related to a porous substrate loaded with porous nano-particles structure and one-step micro-plasma production method thereof. Due to the micro-plasma system enables to enhance the electron density and promotes reaction speed in the reaction without generating thermal effect, the present invention is allowed to be performed at atmosphere environment. The nano-particles also can be quickly obtained by aforementioned micro-plasma system. The electromagnetic field generated by the micro-plasma can drive the nano-particles to be loaded onto the porous substrate in a one step, rapid and low cost process to improve the conventional techniques which requires relatively long procedure time and complicated process.

  • Patent number: 10124327
    Abstract: A method of producing nano-composites has the following steps: providing a solution, with the solution having a substrate and a precursor of a zero-dimensional nanoparticles; and subjecting a surface of the solution to a plasma to activate the precursor to generate the zero-dimensional nanoparticles in the solution. The nanoparticles are self-assembled on the substrate uniformly to generate the nano-composites.

  • Patent number: 9708190
    Abstract: A method for producing a modified graphene includes the steps of intercalating or inserting a mixture of intercalating agents in a spacing between interlayers of carbon substrates or between carbon substrates, whereby the binding force between the interlayers of the carbon substrates or between the carbon substrates is weakened; and then exfoliating the pretreated carbon substrates to form the modified graphene. With the environmental friendly purpose, the method according to the present invention is useful for reducing the total amount of a strong acid. Therefore, the amount of the generated oxygen-containing functional groups attached on the modified graphene is modulated to avoid defects and maintain a yield over 80%.
