Abstract:
The present invention relates to a method for preparing 6-substituted amino-3-cyanoquinoline compounds (compound A for short) and the intermediates thereof, more particularly, to a compound of the following formula (I), the preparation method thereof, the intermediates thereof and use thereof for preparing the compound A. The compound of the formula (I) is cyclized in the presence of an alkali to give a compound of formula A, wherein W is OH; or the compound of the formula (I) is cyclized in the presence of an alkali, and then chlorinated to give a compound of the formula A, wherein W is Cl. Compared with the known methods in the literature, the method for preparing the compound A from the compound of formula (I) according to the present invention can avoid using high-temperature condition and high boiling point solvents, and is safe and environment-friendly, mild in reaction condition, easy in operation with a high yield and high product purity.

The present disclosure relates to a semiconductor nanostructure. The semiconductor nanostructure includes a substrate and at least one ridge. The substrate includes a first crystal plane and a second crystal plane perpendicular to the first crystal plane. The at least one ridge extends from the first crystal plane along a crystallographic orientation of the second crystal plane. A width of cross section at a position of half the height of the at least one ridge is less than 17 nm. The semiconductor nanostructure is a patterned structure which can lead to generate a quantum confinement effect, such that the impurity scattering phenomenon is reduced.
Abstract:
The present invention relates to a process for manufacturing a ramie fabric and the fabric. The process comprising the following step: blend spinning a high-count ramie fiber such as a ramie fiber of 2500Nm or higher with a water-soluble fiber as carrier to form a yarn; sizing the yarn at a low temperature; weaving the yarn to form a gray fabric; then removing the water-soluble fiber from the gray fabric by deweighting the gray fabric during a finishing process after printing and dyeing to obtain a super-high-count ramie fabric with a ramie yarn fineness of 160Nm or higher.
Abstract:
A sample hold circuit is provided for use in a time-interleaved A/D converter apparatus including a plurality of low-speed pipeline A/D converters which are parallelized. The sample hold circuit includes a sampling capacitor and a sample hold amplifier, and operates to sample and hold an input signal by using a switched capacitor. An adder circuit of the sample hold circuit adds a ramp calibration signal to the input signal, by inputting the ramp calibration signal generated to have a frequency identical to that of a sampling clock signal and a predetermined slope based on the sampling clock signal, into a sample hold amplifier via a calibration capacitor having a capacitance smaller than that of the sampling capacitor.
Abstract:
Seed coat color is a very important trait in oilseed type Brassica crops. Identification of the genes controlling the seed coat color is essential to the manipulation of these genes to develop new yellow-seeded germplasm for oilseed breeding The Brassica rapa Transparent Testa Glabra (TTG1) and Transparent Testa (TT1) genes may be used to control seed coat color in Brassica plants.
Abstract:
A system (10) for removing carbon dioxide from a process gas generated during the combustion of a fuel comprises at least one absorption vessel (12, 14) through which the process gas may be forwarded. The absorption vessel (12, 14) is provided with a sorbent material (50) which is operative for reversibly collecting carbon dioxide from the process gas being forwarded through the sorbent material (50). The sorbent material (50) comprises at least one amine, at least one carbon dioxide activating catalyst, and at least one porous material supporting the at least one catalyst and the at least one amine.

Abstract:
Holographic recording drives encode data for recording into a holographic medium. The steps comprise run length limited encoding three bytes of data into 5×5 matrix information, the data subject to a 4-byte error correction code; and providing the 5×5 matrix information to a spatial light modulator (SLM), as a portion of a two-dimensional pixel matrix of the spatial light modulator, for recording into a holographic image on the holographic medium.
Abstract:
A sphere decoding method applied to a MIMO channel is provided. Multiple constellation points of an nth detection layer corresponding to a MIMO channel matrix are enumerated based on an enumeration rule, and at least one nth sub-set of the nth detection layer is defined. K constellation points are obtained from each of the at least one nth sub-set as preferred points, and Kn preferred points are selected from all the K preferred points of the at least one nth sub-set. K1 preferred points are transferred to a second detection layer from a first detection layer. K(T−1) preferred points are transferred to a Tth detection layer from a (T−1)th detection layer. An optimal solution is determined according to Kn preferred points of the nth detection layer. K and at least one of K1 to KT are determined by the The characteristic of the MIMO channel matrix.
