摘要:
A stacked interconnect structure includes a first conductive layer, a second conductive layer, and a first dielectric layer disposed between the first and second conductive layers and having an air gap in a portion of the first dielectric layer that separates the first and second conductive layers. A second dielectric layer is parallel to the first conductive layer, a third dielectric layer overlays a portion of the second dielectric layer and contacts two opposing surfaces of the second conductive layer. A first via extends into the air gap of the first dielectric layer, wherein the second conductive layer is separated from the first via by a portion of the third dielectric layer that extends from a given surface of the third dielectric layer to the second dielectric layer, and a second via that extends from the given surface of the third dielectric layer to the second conductive layer.

Photo-conducting infrared sensors are provided including a substrate (e.g., silicon) with one or more trenches formed on a first surface. An infrared-reflective film can be deposited directly or indirectly onto and conforming in shape with the first surface of the substrate. A lead chalcogenide film can be deposited directly or indirectly over the top of the infrared-reflective film and conforming in shape with the first surface of the substrate. Accordingly, the infrared-reflective film is directly or indirectly sandwiched between the substrate and the lead chalcogenide film.
摘要:
Increasing the concentration of prolines, such as 2-hydroxy-5-oxoproline, in the foliar portions of plants has been shown to cause an increase in carbon dioxide fixation, growth rate, dry weight, nutritional value (amino acids), nodulation and nitrogen fixation, photosynthetically derived chemical energy, and resistance to insect pests over the same properties for wild type plants. This can be accomplished in four ways: (1) the application of a solution of the proline directly to the foliar portions of the plant by spraying these portions; (2) applying a solution of the proline to the plant roots; (3) genetically engineering the plant and screening to produce lines that over-express glutamine synthetase in the leaves which gives rise to increased concentration of the metabolite, 2-hydroxy-5-oxoproline (this proline is also known as 2-oxoglutaramate); and (4) impairing the glutamine synthetase activity in the plant roots which causes increased glutamine synthetase activity in the leaves which gives rise to increased concentration of 2-hydroxy-5-oxoproline. Prolines have also been found to induce similar effects in algae.

A high-efficiency lateral multi-junction solar cell (C) includes ultra-low profile planar spectral band splitting micro-optics having a shortpass filter (48) reflecting desired frequencies of light (24) to a reflective mirror (58) combined with spectrally optimized photovoltaic (solar) cells.
摘要:
The invention relates to transgenic plants exhibiting dramatically enhanced growth rates, greater seed and fruit/pod yields, earlier and more productive flowering, more efficient nitrogen utilization, increased tolerance to high salt conditions, and increased biomass yields. In one embodiment, transgenic plants engineered to over-express both glutamine phenylpyruvate transaminase (GPT) and glutamine synthetase (GS) are provided. The GPT+GS double-transgenic plants of the invention consistently exhibit enhanced growth characteristics, with T0 generation lines showing an increase in biomass over wild type counterparts of between 50% and 300%. Generations that result from sexual crosses and/or selfing typically perform even better, with some of the double-transgenic plants achieving an astounding four-fold biomass increase over wild type plants.

A method for growing a SiC-containing film on a Si substrate is disclosed. The SiC-containing film can be formed on a Si substrate by, for example, plasma sputtering, chemical vapor deposition, or atomic layer deposition. The thus-grown SiC-containing film provides an alternative to expensive SiC wafers for growing semiconductor crystals.

The disclosure relates to a high purity 2H-SiC composition and methods for making same. The embodiments represented herein apply to both thin film and bulk growth of 2H-SiC. According to one embodiment, the disclosure relates to doping an underlying substrate or support layer with one or more surfactants to nucleate and grow high purity 2H-SiC. In another embodiment, the disclosure relates to a method for preparing 2H-SiC compositions by nucleating 2H-SiC on another SiC polytype using one or more surfactants. The surfactants can include AlN, Te, Sb and similar compositions. These nucleate SiC into disc form which changes to hexagonal 2H-SiC material.

Glutamine phenylpyruvate transaminase (GPT) proteins, nucleic acid molecules encoding GPT proteins, and uses thereof are disclosed. Provided herein are various GPT proteins and GPT gene coding sequences isolated from a number of plant species. As disclosed herein, GPT proteins share remarkable structural similarity within plant species, and are active in catalyzing the synthesis of 2-hydroxy-5-oxoproline (2-oxoglutaramate), a powerful signal metabolite which regulates the function of a large number of genes involved in the photosynthesis apparatus, carbon fixation and nitrogen metabolism.
