摘要： The embodiments herein provide a filter for cigarette comprising graphene nano-composite based material enclosed in a casing. The filter is reusable and is plugged to any cigarette, or tobacco smoking products. The filter is a stand-alone product or manufactured integrally with each individual cigarette. The filter provides a safe smoking option to tobacco smokers without changing their smoking habits by reducing the tar content and other toxic chemicals in the inhaled smoke. The graphene based nanocomposite filter adsorbs the toxic agents from the smoke (of cigarette, beedi, hookah etc). The filter is fabricated by treating ceramic particles and coating them with carbon particles. The carbon particles are carbonized. The ceramic particles coated with carbon are segregated based on shape and size and treated chemically to convert carbon into graphene under inert conditions. The graphene coated particles are chemically functionalized for improved filtration.

摘要： A method for manufacturing a graphitic sheet is used to obtain the graphitic sheet with similar characteristics to graphene. The method includes forming an octadecyltrichlorosilane (OTS) layer on a substrate to obtain a composite. The composite is annealed at 250-400° C. for 30-90 minutes, forming the graphitic sheet on the substrate via self-assembly of octadecyltrichlorosilane (OTS) in the OTS layer. The annealed composite is immersed in water, followed by being sonicated for 2 minutes with a frequency of 40 kHz and a power output of 200 W, to separate the graphitic sheet from the substrate.

摘要： Cutting elements include at least one metal diffused into interbonded grains of diamond. Earth-boring tools include at least one such cutting element. Methods of forming cutting elements may include forming a mixture of the at least one metal salt and a plurality of grains of hard material and sintering the mixture to form a hard polycrystalline material. During sintering, the metal salt may melt or react with another compound to form a liquid that acts as a lubricant to promote rearrangement and packing of the grains of hard material. The metal salt may, thus, enable formation of hard polycrystalline material having increased density, abrasion resistance, or strength. The metal salt may also act as a getter to remove impurities (e.g., catalyst material) during sintering. The methods may also be employed to form cutting elements and earth-boring tools.

摘要： The present disclosure relates a spark plasma sintered polycrystalline diamond and methods of spark plasma sintering leached polycrystalline diamond. Spark plasma sintering produces plasma from a reactant gas found in the pores left by catalyst removal from leached polycrystalline diamond. The plasma forms diamond bonds and/or carbide structures in the pores, which may produce polycrystalline diamond that is has a higher impact strength than the leached polycrystalline diamond or other improved properties.
