A stack of heat generating integrated circuit chips may be provided with intervening cooling integrated circuit chips. The cooling integrated circuit chips may include microchannels for the flow of the cooling fluid. The cooling fluid may be pumped using the integrated electroosmotic pumps. Removal of cooling fluid gases may be accomplished using integrated re-combiners in some embodiments.

SHE, a Starch Hydrolytic Enzyme active in maize endosperm (Zea mays), and the cDNA sequence encoding SHE are disclosed. The specificity of native, purified SHE is similar, in general terms, to previously known alpha-amylases. However, the activity of SHE toward amylopectin results in hydrolysis products that are distinctly different from those of other alpha-amylases. SHE, and its homologous equivalents in other plants such as rice, Arabidopsis, apple and potato, can be used in starch processing for generating different, e.g., larger sized, alpha-limit dextrins for industrial use, as compared to those generated by previously known alpha-amylases or other starch hydrolytic enzymes. In addition, modification of the expression of this enzyme in transgenic maize plants or in other transgenic organisms (including bacteria, yeast, and other plant species) can be useful for the generation of novel starch forms or altered starch metabolism.
摘要:
A method for preparing porous silicon in which an oxidized single crystal silicon wafer is first bonded to a polycrystalline wafer. The oxidized high quality wafer is then thinned to the desired thickness by grinding and polishing. An oxide may then be deposited on the wafer and patterned to expose regions were the porous silicon will be formed. The single crystal silicon wafer may then etched in the unmasked areas of the pattern to thin the single crystal silicon wafer to the desired thickness in the range of 0.1 microns to 1.0 microns. Next, the porous silicon may be formed using standard techniques. Once the porous silicon is formed the polycrystalline silicon wafer may be ground away and the oxide layer may be undercut to expose the porous silicon. Finally, an appropriate liner material may be applied to the porous silicon.

摘要:
The maize gene dull1 (du1) of the present invention is a determinant of the structure of endosperm starch. Mutations of du1 affect the activity of at least two enzymes involved in starch biosynthesis, namely the starch synthase, SSII, and the starch branching enzyme, SBEIIa. Du1 codes for a predicted 1674 residue protein, and is expressed with a unique temporal pattern in endosperm but is undetectable in leaf or root. The size of the Du1 product and its expression pattern match precisely the known characteristics of maize SSII. The Du1 product contains two different repeated regions in its unique amino terminus, one of which is identical to a conserved segment of the starch debranching enzymes. The cDNA provided for in the present invention encodes SSII, and mutations within this gene affect multiple aspects of starch biogenesis by disrupting an enzme complex containing starch synthase(s), starch branching enzyme(s), and possibly starch debranching enzyme.
摘要:
A method of forming a semiconductor device is described. In that method, a masking layer is formed on a substrate. A layer of photoresist is then deposited and patterned on that layer to expose a first part of the masking layer while covering a second part of the masking layer. After the exposed part of that layer is etched, the resulting device is exposed to a plasma generated from a forming gas. Part of the second part of the masking layer is then removed by exposing the resulting device to a solution, while part of the second part of the masking layer is retained.
摘要:
SU1, a starch debranching enzyme active in maize endosperm (Zea mays), and the cDNA and gene sequences encoding SU1 are disclosed. The amino acid sequence is significantly similar to that of bacterial isoamylases, enzymes that hydrolyze .alpha.-(1.fwdarw.6) glycosidic bonds. Amino acid sequence similarity establishes SU1 as a member of the .alpha.-amylase superfamily of starch hydrolytic enzymes. Also disclosed are antibodies reactive with the SU1 protein, methods of producing antibodies to the SU1 protein, methods of producing fusion proteins including SU1 and methods of producing transgenic plants with a modified su1 gene. The expressed SU1 protein can serve as a replacement for the bacterial and fungal enzymes currently used in the starch processing industry.
