20100151249 | METHODS FOR PREODUCING COATED PHOSPHORS AND HOST MATERIAL PARTICLES USING ATOMIC LAYER DEPOSITION METHODS - Layers of a passivating material and/or containing luminescent centers are deposited on phosphor particles or particles that contain a host material that is capable of capturing an excitation energy and transferring it to a luminescent center or layer. The layers are formed in an ALD process. The ALD process permits the formation of very thin layers. Coated phosphors have good resistance to ambient moisture and oxygen, and/or can be designed to emit a distribution of desired light wavelengths. | 06-17-2010 |
20100178481 | PROTECTIVE COATINGS FOR ORGANIC ELECTRONIC DEVICES MADE USING ATOMIC LAYER DEPOSITION AND MOLECULAR LAYER DEPOSITION TECHNIQUES - Coatings are applied on a flexible substrate using atomic layer deposition and molecular layer deposition methods. The coatings have thickness of up to 100 nanometers. The coatings include layers of an inorganic material such as alumina, which are separated by flexibilizing layers that are deposited with covalent chemical linkage to the inorganic material and which are one or more of silica deposited by an atomic layer deposition process; an organic polymer that is deposited by a molecular layer deposition process, or a hybrid organic-inorganic polymer that is deposited by an molecular layer deposition process. | 07-15-2010 |
20100215897 | METAL FERRITE SPINEL ENERGY STORAGE DEVICES AND METHODS FOR MAKING AND USING SAME - 1-100 nm metal ferrite spinel coatings are provided on substrates, preferably by using an atomic layer deposition process. The coatings are able to store energy such as solar energy, and to release that stored energy, via a redox reaction. The coating is first thermally or chemically reduced. The reduced coating is then oxidized in a second step to release energy and/or hydrogen, carbon monoxide or other reduced species. | 08-26-2010 |

20120077082 | Lithium Battery Electrodes with Ultra-thin Alumina Coatings - Electrodes for lithium batteries are coated via an atomic layer deposition process. The coatings can be applied to the assembled electrodes, or in some cases to particles of electrode material prior to assembling the particles into an electrode. The coatings can be as thin as 2 â„«ngstroms thick. The coating provides for a stable electrode. Batteries containing the electrodes tend to exhibit high cycling capacities. | 03-29-2012 |
20120100301 | Nucleation of Ultrathin, Continuous, Conformal Metal Films Using Atomic Layer Deposition And Application As Fuel Cell Catalysts - A method to achieve a conformal ultrathin film of platinum or one of its alloys on a substrate that can be economically used as a heterogeneous catalyst, such as automotive polymer electrolyte membrane (PEM) fuel cell catalyst. The method includes using a hydrogen plasma in platinum atomic layer deposition along with tungsten as a substrate or anchoring adhesive layer to assist platinum nucleation and deposition. | 04-26-2012 |
20120121932 | Molecular Layer Deposition Process For Making Organic Or Organic-Inorganic Polymers - Ultrathin layers of organic polymers or organic-inorganic hybrid polymers are deposited onto a substrate using molecular layer deposition methods. The process uses vapor phase materials which contain a first functional group and react only monofunctionally at the surface to add a unit to the polymer chain. The vapor phase reactant in addition has a second functional group, which is different from the first functional group, or a blocked, masked or protected functional group, or else has a precursor to such a functional group. | 05-17-2012 |
