20110266493 | Method of forming encapsulated carbon nanotubes - The method of forming encapsulated carbon nanotubes includes first forming a calcium chloride solution and a sodium hydrogen carbonate solution. A volume of carbon nanotubes are added to the calcium chloride solution and the calcium chloride solution and the volume of carbon nanotubes are then mixed with the sodium hydrogen carbonate solution to form a supersaturated calcium carbonate solution. Carbon nanotubes embedded in calcium carbonate crystals are precipitated from the supersaturated calcium carbonate solution. The carbon nanotubes embedded in the calcium carbonate crystals, forming the precipitate, are then filtered from the solution. The filtered carbon nanotubes embedded in the calcium carbonate crystals are washed and then dried, producing a usable volume of carbon nanotubes encapsulated within calcium carbonate crystals. | 11-03-2011 |

20130270188 | GRAPHENE BASED FILTER - Two-dimensional material based filters, their method of manufacture, and their use are disclosed. The filters may include at least one active layer disposed on a porous substrate. The at least one active layer may include intrinsic and/or intentional formed pores. In some embodiments, the flow resistance of the porous substrate may be selected to limit flow through defects and intrinsic pores in the at least one active layer. | 10-17-2013 |
20150122727 | MITIGATING LEAKS IN MEMBRANES - Two-dimensional material based filters, their method of manufacture, and their use are disclosed. In one embodiment, a membrane may include an active layer including a plurality of defects and a deposited material associated with the plurality of defects may reduce flow therethrough. Additionally, a majority of the active layer may be free from the material. In another embodiment, a membrane may include a porous substrate and an atomic layer deposited material disposed on a surface of the porous substrate. The atomic layer deposited material may be less hydrophilic than the porous substrate and an atomically thin active layer may be disposed on the atomic layer deposited material. | 05-07-2015 |
20150176106 | HIGH-DENSITY AND HIGH-STRENGTH WC-BASED CEMENTED CARBIDE - The synthesis of high performance WC—Co cemented carbides which can be efficiently used in the cutting tool industry. WC with different particle sizes and different grain growth inhibitors were consolidated through spark plasma sintering technique and to form a cemented carbide with best combination of mechanical properties. VC and Cr | 06-25-2015 |
20150252451 | HIGH PERFORMANCE ALUMINUM NANOCOMPOSITES - The high performance aluminum nanocomposites are formed by a combination of mechanical alloying and Spark Plasma Sintering (SPS) in order to obtain reinforced nanostrutured aluminum alloys, The nanocomposites are formed from aluminum metal reinforced with silicon carbide (SiC) particulates, wherein the SiC particulates have a particle diameter between about 20 and 40 nm. The nanocomposites are prepared by mixing aluminum-based metal, e.g., Al-7Si-0.3Mg, (Al=92.7%, Si-7% and Mg=0.3%), with SiC nanoparticles in a conventional mill to form a uniformly distributed powder, which is then sintered at a temperature of about 500° C. for a period up to about 20 hours to consolidate the silicon carbide particulates in order to obtain the reinforced aluminum metal-based silicon carbide nanocomposite. | 09-10-2015 |
