Abstract:
A method produces metal-organic framework. In one embodiment a method for producing a metal-organic framework comprises contacting a porous support with a solution comprising a metal and a solvent, contacting a porous support with a solution comprising a ligand and a second solvent, and heating the support for a period of time suitable to substantially evaporate the solution and produce crystals on the surface and the pores.
Abstract:
A method for forming a dispersible nonwoven substrate in an aqueous medium including: a) forming an aqueous nonwoven binder including a selected emulsion polymer wherein the polymer has been modified with a compound comprising a tri-substituted N-atom, the compound having a pKb of from 4 to 7; b) contacting a nonwoven substrate with the aqueous nonwoven binder; c) heating the contacted nonwoven to a temperature of from 120 °C to 220 °C; and d) immersing the contacted heated nonwoven in an aqueous medium having a final pH
Abstract:
A method is disclosed to form a patterned epitaxy template, on a substrate, to direct self-assembly of block copolymer for device lithography. A resist layer on a substrate is selectively exposed with actinic (e.g. UV or DUV) radiation by photolithography to provide exposed portions in a regular lattice pattern of touching or overlapping shapes arranged to leave unexposed resist portions between the shapes. Exposed or unexposed resist is removed with remaining resist portions providing the basis for a patterned epitaxy template for the orientation of the self-assemblable block copolymer as a hexagonal or square array. The method allows for simple, direct UV lithography to form patterned epitaxy templates with sub-resolution features.
Abstract:
A method of forming a self-assembled block polymer layer, oriented to form an ordered array of alternating domains, is disclosed. The method involves providing a layer of the self-assemblable block copolymer on the substrate and depositing a first surfactant onto the external surface of the layer prior to inducing self-assembly of the layer to form the ordered array of domains. The first surfactant has a hydrophobic tail and a hydrophilic head group and acts to reduce the interfacial energy at the external surface of the block copolymer layer in order to promote formation of assembly of the block copolymer polymer into an ordered array having the alternating domains.
Abstract:
An architectural construct is a synthetic material that includes a matrix characterization of different crystals. An architectural construct can be configured as a solid mass or as parallel layers that can be on a nano-, micro-, and macro-scale. Its configuration can determine its behavior and functionality under a variety of conditions. Implementations of an architectural construct can include its use as a substrate, sacrificial construct, carrier, filter, sensor, additive, and catalyst for other molecules, compounds, and substances, or may also include a means to store energy and generate power.

Abstract:
The present invention describes the synthesis of silicon-containing monomers and copolymers. The synthesis of a monomer, trimethyl-(2-methylenebut-3-enyl)silane (TMSI) and subsequent synthesis of diblock copolymer with styrene, forming polystyrene-block-polytrimethylsilyl isoprene, and synthesis of diblock copolymer Polystyrene-block-polymethacryloxymethyltrimethylsilane or PS-b-P(MTMSMA). These silicon containing diblock copolymers have a variety of uses. One preferred application is as novel imprint template material with sub- 100 nm features for lithography.
