Abstract:
It is intended to provide a method for producing aglycone from a glycoside efficiently at low cost without using an acid catalyst or an organic solvent. The method for producing aglycone, characterized by bringing a glycoside into contact with high temperature high pressure water. The temperature of the high temperature high pressure water is generally from 100 to 374°C, preferably from 140 to 320°C, more preferably from 200 to 300°C. The pressure of the high temperature high pressure water may be not lower than the saturated water vapor pressure at the temperature, i.e., a pressure at which the liquid state is maintained.

Abstract:
A process for efficiently producing a polysaccharide from coffee beans or/and a coffee extraction residue. Use of these has not received attention because of difficulty in decomposing these. The process, which is for producing a polysaccharide from coffee beans or/and a coffee extraction residue, comprises: a step (a) in which the coffee beans or/and coffee extraction residue are reduced to particles having a diameter of 10.0 µm to 5.0 mm; a step (b1) in which after the step (a), the particles are heated at 50-100°C in the presence of a dilute alkali; a step (c1) in which after completion of the step (b1), cellulase is caused to act thereon; a step (b2) in which after the step (c1), a heat treatment is conducted at 120°C or higher in the presence of a dilute alkali; and a step (c2) in which after the step (b2), cellulase is caused to act thereon.
Abstract:
The present invention provides an organometallic complex having a high quantum efficiency even in a polymer thin film as a emitting material for organic electroluminescent (EL) element. The present invention relates to an organoiridium complex for an organic electroluminescent element represented by the following Formula; wherein a C-N ligand including two atomic groups (A 1 , A 2 ), and a β-diketone) ligand in line symmetry having two tert-butyl-substituted phenyl groups are coordinated with an iridium atom. The organoiridium complex of the present invention has a high quantum efficiency even in a polymer thin film with respect to green to yellow electroluminescence.
(In the aforementioned Formula, R 1 , R 2 , and R 3 are each a tert-butyl group or a hydrogen atom, and have at least one tert-butyl group; they may bond each other to thereby form a saturated hydrocarbon ring, when having two tert-butyl groups; A 1 , A 2 are each an unsaturated hydrocarbon ring, at least one is a single ring, and at least one is a heterocyclic ring.)
Abstract:
A detection device (100) detects an analyte that may be contained in a specimen. The detection device (100) includes a plurality of gold nanoparticles, an optical trapping light source (101), an illumination light source (102), an objective lens (103), an image pick-up device (108), and a computation unit (106). The plurality of gold nanoparticles are each modified with a probe DNA allowing the analyte to specifically adhere thereto. The optical trapping light source (101) emits polarized light for assembling the plurality of gold nanoparticles together. The objective lens (103) focuses and introduces the polarized light into a liquid containing a specimen and the plurality of gold nanoparticles. The image pick-up device (108) receives light from the liquid. The computation unit (106) detects an analyte based on a signal received from the image pick-up device (108).
Abstract:
The present application relates to a method whereby a plurality of characteristic vectors which are extracted from image data are logged in a database together with the image data for approximate nearest neighbor searching, and has as an objective reducing computation time and memory use. L groups of K hash tables are generated, and each characteristic vector is respectively logged with each hash table. With one group as a copy destination, another group as a copy source, and each respective division by combination of logging bin of the K hash tables of each group as a bucket: 1) a given characteristic vector is focused on; 2) another characteristic vector which is logged in the same bucket in the copy source as the characteristic vector is identified; 3) a characteristic vector is selected in which a number of groups in which the other characteristic vector is logged in the same bucket as the characteristic vector which is focused on is greater than or equal to a prescribed threshold; and 4) when the characteristic vector which is selected in 3) is not logged in each bin of the copy destination in which the characteristic vector being focused on is logged, the characteristic vector is logged in each bin. After focusing on a prescribed number of characteristic vectors and executing 1) - 4) foregoing for each characteristic vector, the copy source hash tables are deleted.
Abstract:
A friction stir processing tool is formed from a Ni-based dual multi-phase intermetallic compound alloy containing rhenium(Re). The Ni-based dual multi-phase intermetallic compound alloy is preferably formed by casting, while gradually cooling, a melt containing all the components of the composition and is preferably heat treated after casting. Moreover, in a method for friction stir processing, a work is softened by friction heat generated when the friction stir processing tool, while rotating, is pressed against the work to be processed. The friction stir processing tool includes the Ni-based dual multi-phase intermetallic compound alloy, and therefore further high hardness is exhibited to improve abrasion resistance, so that even a long period of friction stir processing can be endured.
