From palm oil valuable compounds like the tocochromanols, carotenoids, phytosterols, and others can be derived. Enrichment to highly concentrated fractions is hindered by the enormous number of components involved, the very low volatility, the very low solubility of many of the compounds in organic solvents, and the high viscosity of the mixtures to be processed. Starting materials for the new process are enriched fractions of tocochromanols (about 20 to about 50 wt.-%) and/or carotenoids (about 10 to 30 wt.-%) from palm oil obtained by conventional processes, or by counter current multistage processes with supercritical carbon dioxide. These processes, not addressed here, may comprise: Removal of free fatty acids, transesterification of the triglycerides to methyl or ethyl esters, removal of the esters, e.g. by short path distillation, separation of the tocochromanol fraction from the carotenoid fraction by cooling. In the new process, fractions derived from crude palm oil, already enriched to some extent in tocochromanols, carotenoids, phytosterols, and others, are being treated by supercritical fluid technology in a unique combination of counter current separation with selective adsorption and desorption using supercritical fluids. A first enrichment, comprising one or more separation steps by application of a near critical or a supercritical fluid in a single or multistage (counter current) separation process is combined appropriately with a second enrichment step wherein the product of the first enrichment step is directly adsorbed on an adsorbent (silicagel) by passing the product flow over a fixed bed of adsorbent without substantial pressure change, and subsequent desorption with the same (or an other) near critical or supercritical fluid at the same or a different pressure as in the first separation, or by a pre-designed sequence of pressures and temperatures. For the tocochromanol enrichment, carbon dioxide at near critical conditions above the critical temperature of carbon dioxide is used. For the carotenoid enrichment, propane at near critical conditions below the critical temperature of propane is used.

摘要:
Data classification is used to classified input items by associating the input items with one or more classes from a set of one or more classes in a data classification system, including identifying relevant features in an input item to form a feature vector for the input item, receiving at the data classification system an indication of a point-of-view, adjusting the feature vector according to the point-of-view indication or modifying a pattern discriminator (e.g., trainer and classifier) to inline-process feature vectors depending on the provided point-of-view (e.g., SVM custom kernels), and classifying the input item into the set of classes according to the point-of-view. The point-of-view data can be introduced either as a pre-process step prior to passing it off to the pattern discrimination algorithm, or can be incorporated directly into the pattern discrimination algorithm if applicable. The pattern discrimination algorithms can detect arbitrary patterns given a similarly prepared dataset during both training and subsequent classification of unclassified documents.

The present disclosure provides a transparent conductive film on P-type layer of GaN-based LED and a fabricating method thereof. The transparent conductive film is fabricated by Ni/ITO, Al/ITO or NiO/ITO. In one embodiment, the thickness of the Ni layer is 5 Å to 30 Å. The thickness of the Al layer is 5 Å to 30 Å. The thickness of the NiO layer is 5 Å to 40 Å. The thickness of the ITO layer is 1000 Å to 3000 Å. In one embodiment, the fabricating method comprises steps of evaporating one of Ni, Al and NiO layers on a P-type GaN layer, heat-treating a wafer on which the Ni or Al layer is evaporated, then evaporating an ITO layer on the surface of Ni, Al or NiO layer, and heat-treating the wafer on which Ni/ITO, Al/ITO or NiO/ITO layers are evaporated. The transparent conductive film can have high light transmittance within the range of visible light and low specific contact resistance.
摘要:
A capped trimming hard-mask patterning process to form ultra-thin structures can include depositing a hard-mask layer over a layer of patterning material, depositing an imaging layer over the hard-mask layer, patterning the imaging layer and the hard-mask layer, selectively trim etching the hard-mask layer to form a pattern hard mask, and removing the portions of the patterning layer using the pattern hard mask formed from the trimmed hard-mask. Thus, the use of thin imaging layer, that has high etch selectivity to the hard-mask layer, allows the use of trim etch techniques without a risk of hard-mask erosion or the aspect ratio pattern collapse. That, in turn, allows for the formation of the ultra-thin pattern with widths less than the widths of the pattern of the imaging layer.

A method for manufacturing low cost electroluminescent (EL) lamps is disclosed. The method of the present invention includes the first step of die cutting, embossing or chemically etching the metal foil surface of a metal foil bonded flexible electrical insulation to simultaneously form one or more rear capacitive electrodes, electrical terminations, optical registration fiducial indicia, and a continuous carrier means that is then coupled to a precisely positioned indexing system. Next, the rear metal foil capacitive electrodes are coated with a capacitive dielectric layer precisely isolating the rear electrode form. In the third step, a layer of electroluminescent phosphor ink is applied to the rear capacitive electrodes to precisely form areas of illumination. In step four, a layer of light transmissive and electrically conductive ink is applied to cover the EL phosphor layer. Next, in step five a transparent polyester film or ultraviolet activated dielectric coating is applied to the entire surface of the lamp.
