    摘要: There is provided a process for preparing a glycidyl derivative from 3-chloro-1,2-propanediol, comprising i) adding a phosphate salt to a solution into which 3-chloro-1,2-propanediol is dissolved into a solvent to produce glycidol, and ii) adding to the solution of step i) a base capable of releasing a glycidyl group from the glycidol and a substrate susceptible to nucleophilic attack to produce the desired glycidyl derivative by nucleophilic attack of the glycidyl group to the substrate.

    摘要: Methods and a structure. A first film of a first block copolymer is formed inside a trough integrally disposed on an energetically neutral surface layer of a substrate. Line-forming microdomains are assembled of the first block copolymer, and form first self-assembled structures within the first film normal to the sidewalls and parallel to the surface layer. At least one microdomain is removed from the first film such that oriented structures remain in the trough oriented normal to the sidewalls and parallel to the surface layer. A second film of a second block copolymer is formed inside the trough. Line-forming microdomains are assembled of the second block copolymer, and form second self-assembled structures within the second film oriented normal to the oriented structures and parallel to the sidewalls. A second method and a structure are also provided.

    摘要: A method and associated structure. A substrate is provided. The substrate has an energetically neutral corrugated surface layer. A film is formed on the corrugated surface layer. The film includes a combination of a di-block copolymer and a stiffening compound. The di-block copolymer includes lamellar microdomains of a first polymer block and lamellar microdomains of a second polymer block. The stiffening compound is dissolved within the first polymer block. At least one lamellar microdomain is removed from the film such that an oriented structure remains on the surface layer.

    摘要: Layered nanostructures are constructed by imprinting material with a mold, while selectively modifying and removing a portion of the mold. The mold, which includes a pattern of features, is modified so that the portion of the mold that includes the features is made chemically and/or physically distinct from the rest of the mold. That portion of the mold that includes the features is retained while the rest of the mold is removed. The retained portion of the mold provides mechanical support for any adjoining layer or layers.
