Abstract:
Disclosed is concrete comprising Portland cement, water, aggregate and bifunctional thermoplastic reinforcing fibers having hydrating functionality and mechanical reinforcing functionality. The thermoplastic reinforcing fibers can be present in concentration sufficient to improve the workability time of the concrete before hardening, and can also suppress cracking during curing compared to an unfilled concrete.
Abstract:
The present invention relates to recombinant host cells polynucleotides and polypeptides, methods for their production, and methods for their use in production of hydrocarbons. Disclosed herein are methods, compositions and hosts for synthesizing hydrocarbons and derivatives thereof. In one non-limiting embodiment, the methods, compositions and hosts are used to synthesize hydrocarbons comprising one or more isoprene units as depicted in Formula I as well as salts or derivatives thereof. An aspect of the present invention relates to a genetically engineered host capable of producing hydrocarbons or derivatives thereof via a mevalonate (MVA) pathway.
Abstract:
Apparatuses and processes for producing yarn having longitudinally variable dye uptake and well as yarns having longitudinally variable dye uptake and articles prepared from these yarns are provided.
Abstract:
This document describes biochemical pathways for producing 7-aminoheptanoic acid using a β-ketoacyl synthase or a β-ketothiolase to form either a 5-amino-3-oxopentanoyl-[ACP] or 5-amino-3-oxopentanoyl-CoA intermediate. 7-aminoheptanoic acid can be enzymatically converted to pimelic acid, 7-hydroxyheptanoic acid, heptamethylenediamine or 1,7-heptanediol or the corresponding salts thereof. This document also describes recombinant microorganisms producing 7-aminoheptanoic acid as well as pimelic acid, 7-hydroxyheptanoic acid, heptamethylenediamine and 1,7-heptanediol or the corresponding salts thereof.
Abstract:
This document describes biochemical pathways for biosynthesizing a 3-oxo-7-hydroxyheptanoyl-CoA intermediate using a β-ketothiolase , and enzymatically converting 3-oxo-7-hydroxyheptanoyl-CoA to 7-hydroxyheptanoic acid. - 7-hydroxyheptanoic acid can be further enzymatically converted to pimelic acid, 7-aminoheptanoic acid, heptamethylenediamine or 1,7-heptanediol. This document also describes recombinant hosts producing 7-hydroxyheptanoic acid as well as pimelic acid, 7-aminoheptanoic acid, heptamethylenediamine and 1,7-heptanediol.
Abstract:
The present disclosure relates to processes for production of alkene products from their alkene precursors, such as 3~hydroxyacid and alcohols, via either (1) high temperature reactive distillation with steam contact at optimal pH, (2) solvent extraction and Mulzer dehydration, (3) solid phase adsorption, desorption into an organic solvent and catalytic reaction and (4) high temperature reactive distillation with steam contact at optimal pH followed by catalytic conversion.
Abstract:
Described herein are processes and apparatus for the high purity and high concentration recovery of multivalent products via continuous ion exchange from aqueous solutions for further down-stream purification.
Abstract:
This document describes a process for the high purity and high concentration recovery of monovalent products via continuous ion exchange from aqueous solution for further downstream purification.
Abstract:
The present invention provides an easy settable stretch fabric comprising three types of yarns: a rigid fiber, an elastic fiber, and a low-melt fiber, wherein the low-melt fiber comprises low-melt polymer which can be fused in the temperature between 60 °C to 200 °C, being higher than the temperature used for normal textile process and household laundry, but lower than the temperature used for heat setting elastic fiber. The low-melt fiber can be selected from a group of fibers made from modified polyester, nylon, and polypropylene and the copolymer from them in the form of staple or filament.
