20090317557 | Process To Make Core-Shell Structured Nanoparticles - Disclosed is a process for making a composite material that contains core-shell structured nanoparticles. The process includes providing a precursor in the form of a powder a liquid and/or a vapor of a liquid that contains a core material and a shell material, and suspending the precursor in an aerosol gas to produce an aerosol containing the precursor. In addition, the process includes providing a plasma that has a hot zone and passing the aerosol through the hot zone of the plasma. As the aerosol passes through the hot zone of the plasma, at least part of the core material and at least part of the shell material in the aerosol is vaporized. Vapor that contains the core material and the shell material that has been vaporized is removed from the hot zone of the plasma and allowed to condense into core-shell structured nanoparticles. | 12-24-2009 |
20090317719 | Material With Core-Shell Structure - Disclosed is a material having a composite particle. The composite particle includes an outer shell containing an element such as carbon, nitrogen, oxygen or sulfur and an inner core made from a lithium alloying material such as tin, silicon, aluminum and/or germanium. If the outer shell is made from carbon, the outer shell of the composite particle has an average thickness of less than 20 nanometers and the composite particle has an outer mean diameter of less than 100 nanometers. In some instances, the inner core is made from tin, a tin binary alloy, a tin tertiary alloy or a tin quaternary alloy. | 12-24-2009 |
20100215960 | HOLLOW CARBON SPHERES - A hollow carbon sphere having a carbon shell and an inner core is disclosed. The hollow carbon sphere has a total volume that is equal to a volume of the carbon shell plus an inner free volume within the carbon shell. The inner free volume is at least 25% of the total volume. In some instances, a nominal diameter of the hollow carbon sphere is between 10 and 180 nanometers. | 08-26-2010 |
20100310784 | PROCESS TO MAKE STRUCTURED PARTICLES - Disclosed is a process for making a composite material that contains structured particles. The process includes providing a first precursor in the form of a dry precursor powder, a precursor liquid, a precursor vapor of a liquid and/or a precursor gas. The process also includes providing a plasma that has a high field zone and passing the first precursor through the high field zone of the plasma. As the first precursor passes through the high field zone of the plasma, at least part of the first precursor is decomposed. An aerosol having a second precursor is provided downstream of the high field zone of the plasma and the decomposed first material is allowed to condense onto the second precursor to from structured particles. | 12-09-2010 |
20110006254 | PROCESS TO MAKE ELECTROCHEMICALLY ACTIVE/INACTIVE NANOCOMPOSITE MATERIAL - A process for making an first material/second material nanocomposite is disclosed. The process can include providing a precursor that contains an electrochemically active and an electrochemically inactive material. Thereafter, the precursor can be suspended in an aerosol gas to produce an aerosol and a plasma having a high field zone can be provided. The aerosol can be passed through the high field zone of the plasma and result in the vaporization of at least part of the precursor in the aerosol. The precursor that has been vaporized in the high field zone is subsequently removed therefrom and allowed to condense into an first material/second material nanocomposite with at least one electrochemically active material. | 01-13-2011 |
20110180513 | HALLOW CARBON SPHERES - A hollow carbon sphere having a carbon shell and an inner core is disclosed. The hollow carbon sphere has a total volume that is equal to a volume of the carbon shell plus an inner free volume within the carbon shell. The inner free volume is at least 25% of the total volume. In some instances, a nominal diameter of the hollow carbon sphere is between 10 and 180 nanometers. | 07-28-2011 |
20130276583 | AEROSOL REDUCTION/EXPANSION SYNTHESIS (A-RES) FOR ZERO VALENT METAL PARTICLES - Various embodiments provide methods of forming zero valent metal particles using an aerosol-reductive/expansion synthesis (A-RES) process. In one embodiment, an aerosol stream including metal precursor compound(s) and chemical agent(s) that produces reducing gases upon thermal decomposition can be introduced into a heated inert atmosphere of a RES reactor to form zero valent metal particles corresponding to metals used for the metal precursor cot pound(s). | 10-24-2013 |
