Abstract:
A method for preparing ethylene glycol from cellulose uses the cellulose as the feed for the reaction. The cellulose conversion is performed over catalysts which are composed of the metallic state, carbides, nitrides, or phosiphides of molybdenum or tungsten, and metallic cobalt, nickel, ruthenium, rhodium, palladium, iridium, and platinum of the group 8, 9, or 10 transition metals. The catalytic conversion of cellulose is conducted at 120 to 300° C. and hydrogen pressure 1 to 12 MPa under the hydrothermal conditions to achieve the high efficiency, high selectivity, and high yield of ethylene glycol. Compared to the existing method of preparing ethylene glycol from ethylene, the method, using the renewable raw material for the reaction, is friendly to the environment, and has high atom economy.

The rotating plate surface facing surface of the wafer or substrate has grooves, regular patterns, and irregular patterns to enhance the cleaning efficiency. Another embodiment further includes an ultra sonic or mega sonic transducer vibrating the rotating plate during cleaning process.
Abstract:
Methods are described in which a sample containing RNA is contacted with an enzyme having an RNA ligation activity in the presence of a labeled substrate to provide labeled RNA. Methods of performing an array analysis of a labeled RNA sample are also described.
Abstract:
A method and system for performing clock calibration and de-skew on a multi-lane high speed serial interface is presented. Each of a plurality of serial lane transceivers associated with an individual bit lane receives a first data frame, comprising a training sequence header pattern. Based on each of the first data frames, the plurality of serial lane transceivers de-skew a plurality of data frames and generate a plurality of event signals. Using the plurality of event signals, a core clock, having a first phase, is adjusted to be phase aligned with the slowest bit lane.
Abstract:
The invention relates to methods for treating samples of RNA. In an embodiment the method includes contacting the sample of RNA with a set of oligodeoxynucleotides to provide a DNA/RNA duplex. The method includes contacting the DNA/RNA duplex with an enzyme having a DNA:RNA nuclease activity to provide a digested RNA sample. Kits in accordance with the invention are also described.
Abstract:
Aspects of the disclosure are generally directed to methods, probes, probe compositions and kits for detecting or quantifying target oligonucleotides. In some embodiments, there are provided methods for determining the level of target oligonucleotides, such as a small RNA (e.g., miRNA), in a sample. In some embodiments, the methods comprise analyzing hybridization of target oligonucleotides to a test microarray; analyzing hybridization of a known amount of reference oligonucleotides (having the same sequences as the target oligonucleotides) to a calibration microarray; and determining the level of the target oligonucleotides in the sample by comparing the hybridization of the target oligonucleotides with the hybridization of the reference oligonucleotides.

Abstract:
A semiconductor component that includes a field plate and a semiconductor device and a method of manufacturing the semiconductor component. A semiconductor material includes an epitaxial layer disposed on a semiconductor substrate. A trench having an upper portion and a lower portion is formed in the epitaxial layer. A portion of a field plate is formed in the lower portion of the trench, wherein the field plate is electrically isolated from trench sidewalls. A gate structure is formed in the upper portion of the trench, wherein a gate oxide is formed from opposing sidewalls of the trench. Gate electrodes are formed adjacent to the gate oxide formed from the opposing sidewalls and a dielectric material is formed adjacent to the gate electrode. Another portion of the field plate is formed in the upper portion of the trench and cooperates with the portion of the field plate formed in the lower portion of the trench to form the field plate.
