Publication number: 20080248306Abstract: The invention relates to the deposition of nanoparticles from the gas phase of the a thermal plasma of a gas discharge and the subsequent attachment of said nanoparticles to the substrate particles. The invention can be used for increasing the flowability of solid bulk material. Particularly the pharmaceutical industry utilizes numerous intermediate and final products in the form of powders which cause processing problems because of the poor flowability thereof. With fine-grained materials, undesired adhesive effects occur foremost because of Van der Waals'forces. Said effects can be reduced by applying nanoparticles to the surface of the material that is to be treated. The invention is characterized by a combined process in which the nanoparticles are produced and are attached to the substrate surface. Using a non-thermal plasma additionally makes it possible to treat temperature-sensitive materials that are often used in the pharmaceutical industry.Type: ApplicationFiled: September 25, 2006Publication date: October 9, 2008Applicant: ETH Zurich, ETH TransferInventors: Adrian Spillmann, Axel Sonnenfeld, Philipp Rudolf Von Rohr

Publication number: 20080199613Abstract: One embodiment thermal chemical vapor deposition method includes exposing a substrate within a chamber to first and second deposition precursors effective to thermally chemical vapor deposit a material on the substrate, and exhausting unreacted first and second deposition precursors from the chamber through a vacuum pump via a first exhaust line comprising a filter. A reactive gas is flowed to the material on the substrate, with the reactive gas being reactive with the material. After flowing the reactive gas, an inert purge gas is flowed through the chamber and through the vacuum pump. The flowing of the inert purge gas to the vacuum pump is through a second exhaust line not comprising the filter. The exposing, the flowing of the reactive gas, and the flowing of the inert purge gas are repeated effective to deposit material of desired thickness on the substrate.Type: ApplicationFiled: February 21, 2007Publication date: August 21, 2008Inventors: Vishwanath Bhat, Gordon Morrison

Publication number: 20080193764Abstract: A fine spherical particle formed of diamond as a core and having carbon nano-materials radially grown therefrom is disclosed, which exhibits the appearance of a Marimo (Cladophora sauteri) particle. Fine diamond catalytic particles 2 whose surfaces are oxidized and treated to carry a transition metal catalyst are floated and stirred in a gas phase of hydrocarbon while being heated at a selected temperature to bring about a catalytic reaction which synthesizes carbon nano-materials and to grow them on the surface of said oxidized fine diamond particle. Nano fibers or filaments 32 of a nano size are grown from the fine diamond catalytic particle 31 as a core to form cladophora-form carbon. The carbon nano-materials if the supported transition metal is Ni or Co become carbon nano-tubes and if it is Pd become coin stacked carbon nano-graphite.Type: ApplicationFiled: May 10, 2005Publication date: August 14, 2008Applicant: NATIONAL INSTITUTE FOR MATERIALS SCIENCEInventors: Toshihiro Ando, Kiyohara Nakagawa, Mika Gamo, Hirokazu Oda
