Abstract:
It relates to a dye compound for solar cells, a dye-sensitized photoelectric converter and dye-sensitized solar cells. The photoelectric conversion efficiency of solar cells is improved by using the dye compound for solar cells, expressed by formula 1: in which X is at least one aromatic group and symmetric about the X—R1 bond axis or at least hetero aromatic group having at least one hetero atom chosen from N and S and symmetric about the X—R1 bond axis; R1 is C1 to C20 cyclic substituted or unsubstituted alkyl or C1 to C20 linear substituted or unsubstituted alkyl; L1 and L2 are substituted or unsubstituted hydrocarbons having 2 to 8 conjugated p-orbitals; Y1 and Y2 are better electro-withdrawing group than X and may contain at least one acidic hydrogen which is able to have hydrogen bond.
Abstract:
Disclosed is a portable terminal including a case having an opening that faces towards a user operating the terminal and a flange protruding towards the opening, a lower window having a partial surface that is attached to a lower surface of the flange, an upper window attached to the lower window to be exposed through the opening, and a liquid crystal panel placed under the lower window. The stress concentrated on and the likelihood of breakage of the flange structure of the portable terminal in which the case is connected with the window is thereby minimized.
Abstract:
Disclosed herein are transglutaminase peptide inhibitors which have inhibitory activity against transglutaminase, and a pharmaceutical composition comprising one of them as an active ingredient. The inhibitors or the composition is useful in the prevention and treatment of various diseases caused by aberrant transglutaminase activation, including inflammatory diseases and cancers. Also, methods for treating various inflammatory diseases and cancers and for preparing mutant peptides capable of inhibiting transglutaminase are also disclosed.
Abstract:
A laminated lens package and a method of fabricating the same are disclosed. The laminated lens package includes a first lens layer including a first lens element formed at one surface thereof through a first mold; a second lens layer including a second lens element formed at one surface thereof through a second mold, corresponding to a location of the first lens element; and a polymer layer provided between the first lens layer and the second lens layer. Accordingly, desired refraction can be implemented by controlling a refractive index. Also, since no spacers are used, defects caused by adhesion of an adhesive agent do not occur. Thus, a fabrication process is simplified, so that productivity can be improved and a fabrication cost can be reduced.
Abstract:
Example embodiments are directed to a method of growing GaN single crystals on a silicon substrate, a method of manufacturing a GaN-based light emitting device using the silicon substrate, and a GaN-based light emitting device. The method of growing the GaN single crystals may include forming a buffer layer including a TiN group material or other like material on a silicon substrate, forming a nano-pattern including silicon oxide on the buffer layer, and growing GaN single crystals on the buffer layer and the nano-pattern.
Abstract:
A content addressable merged queue (camQ) architecture for high-speed switch fabrics reduces the memory requirement for crossbar switch input and output queues using memory cells and age tag comparators. CamQ emulates VOQ FIFO for each supporting priority, eliminating HOL blocking. Multiple QoS levels are supported cost effectively at higher traffic bandwidth limits. Content addressable memory (CAM) cells store payload destinations, which can be addressed by cell priorities. Once a priority for QoS is decided, all the cells with the selected priority in the payload can make connection requests to destination ports directly through the CAM structure. An age tag is assigned to incoming cells and fast age tag comparators provide FCFS features by selecting the oldest cell. Small memory sizes prevent the bottlenecking in ingress and egress queues. A CIOQ crossbar has a fast switching speed, emulating a FIFO output queue switch. Age and priority are interleaved to schedule switching.
Abstract:
A light source for wavelength conversion which can control gray scale includes a semiconductor laser including at least two radiators, to which different gray scale levels are allocated. Further included is a second-harmonic generator for performing wavelength conversion on lights radiated from the radiators, and outputting the wave-converted lights.
Abstract:
An image scanning apparatus for realizing an image on a screen includes: a spatial light modulator module for diffracting light beams having different wavelengths into relevant modes; and an iris for limiting light beams of modes except a mode of 0th-order among the modes diffracted by the spatial light modulator module.
