at separate positive and negative charges), the invention overcomes these limitations. The method provides a thinner film and precise structural control, with at least one layer of a dipolar material. The method also allows an optional interlayer between the substrate and the film for adhesion or as a buffer. The invention facilitates the preparation of a large variety of films for different environments, fabricated on substrates made from various materials in various shapes. The film thickness can be increased by adding layers to match the requirements of various devices. The technology is licensed to NanoSonic, a Blacksburg based business spun out from Virginia Tech.
Former FEORC research scientist Yanjing Liu and former chemistry professor Guy A. Schick received a patent for "Patterned molecular self-assembly" (6,492,096). In other words, films are able to self-assemble on patterned supports. The film may be a monolayer or several layers. The self-assemblies of the invention are uniform, better defined, and have a higher resolution than previous molecular self-assemblies. The process is easier as the patterning techniques do not require etching, which may damage the layers, or stamping, which may lead to uneven application of the film. Potential uses include full color flat displays, membrane separation, conducting and insulating circuits, optical and nonlinear optical devices, and multi-element chemical sensors. This technology is also licensed to NanoSonic.
In Kyeong Yoo, who received his Ph.D. at Virginia Tech and was a research scientist in materials engineering science from 1991 to 1993, received three patents for inventions developed while he was at Virginia Tech. He is now director of Samsung Advanced Institute of Technology in Suwon, Korea, and the patents are shared by Samsung and VTIP. The first patent is for "2T-1C ferroelectric random access memory (FRAM) and operation method thereof" (6,404,667), a method to perform write/read operatPage: 1 2 3 4 5 6 7 8 9 10 11 12 Related biology news :1
