摘要： A Zymomonas integrant posseses the ability to ferment pentose into ethanol. The operon encoding for the pentose-fermenting enzymes are integrated into the Zymomonas genome in a two-integration event of homologous recombination and transposition. Each operon may include more than one pentose-reducing enzyme encoding sequence. The integrant in some embodiments includes enzyme sequences encoding xylose isomerase, xylulokinase, transketolase and transaldolase. The Zymomonas integrants are highly stable, and retain activity for producing the pentose-fermenting enzyme for between 80 to 160 generations. The integrants are also resistant to acetate inhibition, as the integrants demonstrate efficient ethanol production even in the presence of 8 up to 16 grams acetate per liter media.
摘要翻译：发酵单胞菌具有将戊糖发酵成乙醇的能力。编码戊糖发酵酶的操纵子在同源重组和转座的双重整合事件中整合到发酵单胞菌基因组中。每个操纵子可以包括多于一种戊糖还原酶编码序列。在一些实施方案中的综合体包括编码木糖异构酶，木酮糖激酶，转酮醇酶和转醛醇酶的酶序列。发酵单胞菌的整合体是高度稳定的，并且保留在80至160代之间产生戊糖发酵酶的活性。整合剂也耐乙酸盐抑制，因为即使在每升培养基中存在8至16克乙酸盐的情况下，整合体也显示有效的乙醇生产。

摘要： A photoelectrochemical-electrochromic device comprising a first transparent electrode and a second transparent electrode in parallel, spaced relation to each other. The first transparent electrode is electrically connected to the second transparent electrode. An electrochromic material is applied to the first transparent electrode and a nanoporous semiconductor film having a dye adsorbed therein is applied to the second transparent electrode. An electrolyte layer contacts the electrochromic material and the nanoporous semiconductor film. The electrolyte layer has a redox couple whereby upon application of light, the nanoporous semiconductor layer dye absorbs the light and the redox couple oxidizes producing an electric field across the device modulating the effective light transmittance through the device.

摘要： The cabin cooling system (10) includes a cooling duct (62) positioned proximate and above upper edges of one or more windows of a vehicle (14) to exhaust hot air as the air is heated by inner surfaces of the windows and forms thin boundary layers of heated air (8) adjacent the heated windows. The cabin cooling system (10) includes at least one fan to draw the hot air into the cooling duct (62) at a flow rate that captures the hot air in the boundary layer (12) without capturing a significant portion of the cooler cabin interior air and to discharge the hot air at a point outside the vehicle cabin (24), such as the vehicle trunk (26). In a preferred embodiment, the cooling duct (62) has a cross-sectional area that gradually increases from a distal point to a proximal point to the fan inlet to delevop a substantially uniform pressure drop along the length of the cooling duct (62). Correspondingly, this cross-sectional configuration develops a uniform suction pressure and uniform flow rate at the upper edge of the window to capture the hot air in the boundary layer (12) adjacent each window.

摘要： The present invention provides a process for etching a corrosion layer, such as oxide or hydroxide, from and concomitantly forming a passivating layer on the surface of metallic nanoparticles. A reaction mixture is prepared by dispersing sodium hexafluoroacetylacetonate (Na(hfa)) and a metallic particle powder having oxide or hydroxide corrosion layers in hexane solvent. The mixture is allowed to react for a time sufficient to etch the oxide or hydroxide groups from the particulate surface and passivate the surfaces with (hfa). Hexane may be evaporated from the mixture and any excess Na(hfa) separated from the reaction mixture by sublimation or rinsing with a polar aprotic solvent. In an embodiment of the present invention, aluminum particles are first etched and passivated and then used to form ohmic contacts with p-type silicon. This etching/passivation improves the electrical properties of the contact.

摘要： A process of using fast pyrolysis in a carrier gas to convert a plastic waste feedstream having a mixed polymeric composition in a manner such that pyrolysis of a given polymer to its high value monomeric constituent occurs prior to pyrolysis of other plastic components therein comprising: selecting a first temperature program range to cause pyrolysis of said given polymer to its high value monomeric constituent prior to a temperature range that causes pyrolysis of other plastic components; selecting a catalyst and support for treating said feed streams with said catalyst to effect acid or base catalyzed reaction pathways to maximize yield or enhance separation of said high value monomeric constituent in said temperature program range; differentially heating said feed stream at a heat rate within the first temperature program range to provide differential pyrolysis for selective recovery of optimum quantities of the high value monomeric constituents prior to pyrolysis of other plastic components; separating the high value monomeric constituents; selecting a second higher temperature range to cause pyrolysis of a different high value monomeric constituent of said plastic waste and differentially heating the feedstream at the higher temperature program range to cause pyrolysis of the different high value monomeric constituent; and separating the different high value monomeric constituent.
