摘要： The invention provides a method for manufacturing nano carbon micro particles, including the following steps: step one: digesting the Malvaceae plants to produce solutions containing lignin; step two: extracting lignin condensation from the solution containing lignin, and then removing salt from the lignin condensation to form material containing lignin; step three: carbonizing the material containing lignin to form carbides; step four: crushing the carbides; step five: performing high-frequency heat treatment on the crushed carbides to obtain carbon micro particles; further including step six: crushing again the carbon micro particles so that the carbon micro particles are nano-sized and finely pulverized. The high-purity carbon micro particles obtained by the present invention have excellent properties in aspects of conductivity, wear resistance, heat resistance, corrosion resistance, etc., which can be used as an electromagnetic sealing material, a wear-resistant material, a heating element, a heat-resistant material, corrosion resistant materials, the application is extremely wide.

摘要： A universal or all-purpose laser marking composition for forming satisfactorily dark laser marks on a wide variety of substrates is provided. The marking composition comprises an enhancer of nitrides, carbides, silicides, and combinations thereof. The enhancer may be selected one or more of ferromanganese, ferrosilicon, FexSi(1-x) where X can range from about 0.005 to 0.995, Fe5Si2, MgFeSi, SiC, CaSi, (Co)Mo, MoSi2, TiSi2, ZrSi2, WSi2, MnSi2, YSi, Cu5Si, Ni2Si, Fe3C, Fe7C3 and Fe2C, MoC, Mo2C, Mo3C2, YC2, WC, Al4C3, Mg2C, Mg2C3, CaC2, LaC2, Ta4C3, Fe2N, Fe3N, Fe4N, Fe7N3, Fe16N2, MoN, Mo2N, W2N, WN, WN2, and combinations thereof and combinations thereof. Upon disposing the marking composition on a substrate and exposing the marking composition to laser radiation, the marking composition absorbs the laser radiation, increases in temperature, chemically bonds with the substrate, and when formed on each of a metal, glass, ceramic, stone, and plastic substrates, the mark has a negative ΔL dark contrast value of at least −1 compared to a mark formed by the marking composition without the enhancer.

摘要： Three-dimensional nanoporous aerogels and suitable preparation methods are provided. Nanoporous aerogels may include a carbide material such as a silicon carbide, a metal carbide, or a metalloid carbide. Elemental (e.g., metallic or metalloid) aerogels may also be produced. In some embodiments, a cross-linked aerogel having a conformal coating on a sol-gel material is processed to form a carbide aerogel, metal aerogel, or metalloid aerogel. A three-dimensional nanoporous network may include a free radical initiator that reacts with a cross-linking agent to form the cross-linked aerogel. The cross-linked aerogel may be chemically aromatized and chemically carbonized to form a carbon-coated aerogel. The carbon-coated aerogel may be suitably processed to undergo a carbothermal reduction, yielding an aerogel where oxygen is chemically extracted. Residual carbon remaining on the surface of the aerogel may be removed via an appropriate cleaning treatment.
