  • Patent number: 10355268
    Abstract: A carbon-metal oxide composite material comprising: (i) carbon-carbon composite particles in which an amorphous carbon black core is bonded to crystalline graphitic carbon shells; and (ii) a metal oxide material bonded with said carbon-carbon composite particles, wherein said metal oxide material is included in an amount of at least about 10 wt. % by weight of said carbon-carbon composite particles and metal oxide material. Alkali-ion batteries containing the above-described composite as anode are also described. Methods for producing the above-described composite are also described. The method can include, for example, subjecting pulverized rubber tire waste to a sulfonation process and pyrolyzing the sulfonated rubber to produce the carbon-carbon composite particles, as described above, followed by admixing and compounding a metal oxide material with the carbon-carbon composite particles.

  • Patent number: 9884804
    Abstract: A method of making solid acid catalysts includes the step of sulfonating waste tire pieces in a first sulfonation step. The sulfonated waste tire pieces are pyrolyzed to produce carbon composite pieces having a pore size less than 10 nm. The carbon composite pieces are then ground to produce carbon composite powders having a size less than 50 ?m. The carbon composite particles are sulfonated in a second sulfonation step to produce sulfonated solid acid catalysts. A method of making biofuels and solid acid catalysts are also disclosed.

  • Publication number: 20080274917
    Abstract: A surface activation method is provided to convert polycarbonate (PC) substrates, e.g., plastic bases of optical discs, to biochip platforms. Such surface activation methods comprise providing an ozone enriched environment in a vicinity of the surface and irradiating the surface with UV radiation. Once activated, the surfaces can be used for DNA probe immobilization and target detection or other bioassays.
