摘要:
Embodiments of the present invention provide polymer matrix nanocomposites reinforced with nano-scale materials such as nanoparticles and carbon nanotubes and methods of fabricating. The nanomaterials are provided within relatively low weight fractions, for example in the range of approximately 0.01 to about 0.4% by weight and distributed within the matrix by a magnetic mixing procedure to provide substantially uniform reinforcement of the nanocomposites. Advantageously, these nanocomposites provide significantly enhanced tensile strength, strain to failure, and fracture toughness over corresponding neat matrices.

The present invention relates to methods and systems for the production of ethanol by cyanobacteria. More specifically, the methods can be used to produce ethanol using genetically engineered light responsive cyanobacteria.
摘要:
A method and system for providing a heat sink are described. The heat sink includes at least one inlet, at least one outlet, a plurality of flow micro-channels, and at least one cross-connect channel. The plurality of flow micro-channels are defined by a plurality of channels walls, connect the inlet(s) with the outlet(s) and accommodate a flow of coolant between the at least one inlet and the at least one outlet. The at least one cross-connect channel is configured to connect at least a portion of the plurality of flow micro-channels. The cross-connect channel(s) also at least partially equilibrate a pressure field for boiling of the coolant across the portion of the plurality of flow micro-channels.
摘要:
The present invention relates to an isolated β-actin nucleic acid promoter molecule from shrimp; nucleic acid constructs including the β-actin promoter molecule; and expression vectors, host cells, and transgenic animals transduced with the isolated β-actin nucleic acid promoter. Also disclosed are methods for imparting to an animal resistance against a pathogen, regulating growth of an animal, increasing stress tolerance in an animal, and increasing cold tolerance in an animal that involves transforming an animal with a nucleic acid construct including the isolated β-actin nucleic acid promoter molecule of the present invention.
摘要:
Methods and compositions are provided for diagnosing and treating Pseudoxanthoma elasticum (PXE) patients and PXE carriers. Methods and compositions are based on the discovery that PXE mutations are located in the MRP6 (ABCC6) gene.
摘要:
The present invention relates to recombinant bacteria genetically engineered from insect hosts to express toxic gene products in a pest insect. The present invention also relates to a method of controlling an insect population using such a recombinant bacteria as a delivery agent throughout an insect colony. The invention also relates to a method of delivering and expressing a gene in an insect.
摘要:
The present invention relates to a semiconductor device for production of a gas from a material comprising the gas using light as the sole power source. In an embodiment, the semiconductor comprises a substrate; a solid-state semiconductor layer disposed on the substrate; a photoactive semiconductor top layer further comprising a photoelectrochemical electrode junction; and an interface layer disposed between the solid-state semiconductor layer and the photoactive semiconductor top layer. A surface of the photoactive semiconductor top layer is exposed to both a source of light such as the sun and to the material, e.g. a liquid electrolyte. The gas is liberated from the material, e.g. hydrogen liberated from a liquid electrolyte. It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.

摘要:
The invention relates to nucleic acid sequences isolated from sugarcane and to methods of using them. In particular, the inventions relates to nucleotide sequences which are derived from sugarcane polyubiquitin genes and which are capable of directing constitutive expression of a nucleic acid sequence of interest that is operably linked to the sugarcane polyubiquitin nucleotide sequences. The sugarcane polyubiquitin nucleotide sequences are useful in regulating expression of a nucleic acid sequence of interest in monocotyledonous and dicotyledonous plants.
