20100178490 | ROLL-TO-ROLL PLASMA ENHANCED CHEMICAL VAPOR DEPOSITION METHOD OF BARRIER LAYERS COMPRISING SILICON AND CARBON - The present invention provides method and process for forming a barrier layer on a flexible substrate. The continuous roll-to-roll method includes providing a substrate to a processing chamber using at least one roller configured to guide the substrate through the processing chamber. The process includes depositing a barrier layer adjacent the substrate by exposing at least one portion of the substrate that is within the processing chamber to plasma comprising a silicon-and-carbon containing precursor gas. The present invention is further directed to a coated flexible substrates comprising a barrier layer based on the structural unit SiC:H. The barrier layer possesses high density and low porosity. Still further, the barrier layer exhibits low water vapor transmission rate (WVTR) in the range of 10 | 07-15-2010 |
20130189446 | LOW PRESSURE HIGH FREQUENCY PULSED PLASMA REACTOR FOR PRODUCING NANOPARTICLES - The present invention provides a low-pressure very high frequency pulsed plasma reactor system for synthesis of nanoparticles. The system includes a chamber configured to receive at least one substrate and capable of being evacuated to a selected pressure. The system also includes a plasma source for generating a plasma from at least one precursor gas and a very high frequency radio frequency power source for providing continuous or pulsed radio frequency power to the plasma at a selected frequency. The frequency is selected based on a coupling efficiency between the pulsed radio frequency power and the plasma. Parameters of the VHF discharge and gas precursors are selected based on nanoparticle properties. The nanoparticle average size and particle size distribution are manipulated by controlling the residence time of the glow discharge (pulsing plasma) relative to the gas molecular residence time through the discharge and the mass flow rates of the nanoparticle precursor gas (or gases). | 07-25-2013 |
20140290804 | SILICON EUTECTIC ALLOY COMPOSITION AND METHOD OF MAKING BY ROTATIONAL CASTING - To carry out a rotational casting method of preparing a silicon eutectic alloy composition, silicon and one or more metallic elements M are melted together to form a eutectic alloy melt comprising the silicon and the one or more metallic elements M. A mold containing the eutectic alloy melt is rotated about a longitudinal axis thereof at a speed sufficient to form a rotating volume of the eutectic alloy melt in contact with an inner surface of the mold. Heat is directionally removed from the rotating volume of the eutectic alloy melt to directionally solidify the eutectic alloy melt, and a eutectic alloy composition, which includes the silicon, the one or more metallic elements M, and a eutectic aggregation of a first phase comprising the silicon and a second phase of formula MSi | 10-02-2014 |
20140291567 | INDUSTRIAL COMPONENT COMPRISING A SILICON EUTECTIC ALLOY AND METHOD OF MAKING THE COMPONENT - An industrial component comprising a Si eutectic alloy comprises a body having a wear surface, where both the body and the wear surface comprise a eutectic alloy including silicon, one or more metallic elements M, and a eutectic aggregation of a first phase comprising the silicon and a second phase of formula MSi | 10-02-2014 |
20150050183 | CONTAINMENT OF MOLTEN MATERIALS HAVING SILICON - Silicon eutectic alloy compositions and methods for making the same are disclosed. In one approach, a method may include using a glass carbon container to restrict contamination of the eutectic alloy melt. In an alternative approach, a method may include using a container having aluminum. The aluminum in the container may provide aluminum that is incorporated into the silicon eutectic alloy. Silicon eutectic bodies made by such methods are also disclosed. | 02-19-2015 |
20150057145 | SILICOTHERMIC REDUCTION OF METAL OXIDES TO FORM EUTECTIC COMPOSITES - A method of making a eutectic alloy body by silicothermic reduction is provided. The method can include heating a mixture including silicon and a metal oxide comprising one or more metallic elements M and oxygen, forming a eutectic alloy melt from the mixture, and removing heat from the eutectic alloy melt, thereby forming the eutectic alloy body having a eutectic aggregation of a first phase comprising the silicon and a second phase being a silicide phase. | 02-26-2015 |
