Compositions containing multifunctional nanoparticles are provided. The compositions are the reaction product of fluoroelastomer having at least one cure site, and the reaction product of nanosilica with more than one type of silane coupling agent. The compositions can be used to form abrasion resistant anti-reflective coatings.
摘要:
The present invention relates to a method for obtaining a carboxylic acid ester from an aqueous solution of the corresponding carboxylic acid ammonium salt using alcoholysis. The recovered carboxylic acid ester may be subsequently hydrolyzed to produce the corresponding carboxylic acid.

Disclosed herein are 3,3,4,4,5,5,6,6,6-nonafluoro-1-hexene compositions for use in refrigeration and air conditioning systems, particularly in centrifugal compressor systems. Also disclosed are 3,3,4,4,5,5,6,6,6-nonafluoro-1-hexene in combination with hydrocarbons, which are azeotropic or near azeotropic.
摘要:
A composite building panel that includes a fabric reinforcing sheet between one of the metal skins and the core of the panel. The fabric reinforcing sheet, which is preferably made from aramid fibers improves the impact resistance and penetration resistance of the building panel without substantially increasing weight and without adding fuel content to the panel system.
摘要:
A method for the facile and inexpensive inducible expression of heterologous genes has been discovered. The yhcS regulator gene has been found to be inducible by aromatic carboxylic acids and to alter the expression of operons in the LysR gene family, including the yhcRQP operon, common in enteric bacteria. Heterologous nucleic acid molecules placed under the control of yhcS responsive promoters may be overexpressed in response to the presence of inexpensive aromatic carboxylic acids.
摘要:
This invention relates to an isolated nucleic acid fragment encoding a 1-deoxy-D-xylulose 5-phosphate reductoisomerase. The invention also relates to the construction of a chimeric gene encoding all or a portion of the 1-deoxy-D-xylulose 5-phosphate reductoisomerase, in sense or antisense orientation, wherein expression of the chimeric gene results in production of altered levels of the 1-deoxy-D-xylulose 5-phosphate reductoisomerase in a transformed host cell.
摘要:
Heat transfer fluids comprising a polytrimethylene ether glycol or random polytrimethylene ether ester glycol, or mixtures thereof, and processes of using them in order to transfer heat.
摘要:
Methods of creating and enhancing insect resistance in plants by introducing non-plant lipases into plants are provided. Plants with enhanced insect resistance and seed from plants thereof are provided. DNA sequences encoding insecticidal lipases and insecticidal lipase gene products that are useful in the practice of this invention are also provided. The compositions and methods of the invention may be used in a variety of agricultural systems for controlling pests, including propagating lineages of insect-resistant crops and targeting expression of these insecticidal lipases to plant organs that are particularly susceptible to infestation, such as roots and leaves.
摘要:
The preparation and use of nucleic acid fragments useful in altering the oil phenotype in plants are disclosed. Chimeric constructs incorporating such nucleic acid fragments and suitable regulatory sequences can be used to create transgenic plants having altered lipid profiles. Methods for altering the oil phenotype in plants using such nucleic acid fragments also are disclosed.
摘要:
A method, apparatus, and system related to field and crop information gathering. In one aspect of the invention, data is obtained from a producer. One example would be yield map data from a yield monitor. Another is “as planted” data from precision farming planting equipment. The data includes information about seed or crop in a producer's field and an identification of the field. The data is combined with other information in a report. The information added could be, for example, soil type information overlaid on the field map. Another example is environmental classification information overlaid on the field map. The report is returned to the producer and used to discuss planning related to the field and the seed or crop.
