Abstract: Proposed is a polymer for a gel-type polymer electrolyte of a secondary battery, in which the polymer is PMVEMA-GMA, which is a polymer obtained by polymerizing (methylvinylether-alt-maleic acid) (PMVEMA) and glycidyl methacrylate (GMA). A gel-type polymer electrolyte including the polymer as a matrix, and a lithium secondary battery including the gel-type polymer electrolyte are also proposed. The polymer of the present disclosure complements a limitation of a liquid electrolyte such as leakage and has a higher ion conductivity than a solid electrolyte. Aside from the advantages, the gel-type polymer electrolyte according to the present disclosure has a higher ion conductivity than a conventional gel-type polymer electrolyte that is based on poly(methylvinylether-alt-maleic acid) (PMVEMA) added with lithium bis(trifluoromethanesulfonyl)imide (LiTFSI) because it can be dissolved well in highly volatile tetrahydrofuran (THF) and thus can be dried at a low temperature.

The composition can include an active ingredient that includes melatonin having a concentration of up to about 250 ?g/kg body weight of the livestock and an agriculturally acceptable carrier.

Abstract: Present disclosure discloses a dense-viewpoint three-dimensional display system and display method thereof, which uses the smallest surface structure that can emit light independently as a display cell. A light-guiding element of an eyebox-generating device guides beams from corresponding display cells to discretely arranged eyeboxes with dense viewpoints. In present disclosure, a display cell projects a beam along a special projecting path to the corresponding viewpoint. Relative to traditional 3D display which takes a pixel as a display unit and lets all sub-pixels of a pixel correspond to a common projecting path, present disclosure can effectively increase the reachable viewpoint number. Furthermore, configuring discretely distributed eyeboxes to keep tracking a viewer's pupils also can reduce necessary viewpoint number for implementing a VAC-free 3D display.

In addition, a metal oxide thin film prepared by the method of the present invention is in the form of a two-dimensional nanosheet, and thus may have a low defect density (high crystallinity) and a wide surface area. Accordingly, based on the improved photosensitivity and photoreactivity, the metal oxide thin film may be utilized in a high-performance photoelectric device.

This method stabilizes the zinc cathode, isolates electrolyte corrosion, inhibits zinc dendrite growth, and addresses issues of dendrite formation, hydrogen evolution, and corrosion, thereby extending the battery's service life.

Abstract: A method and apparatus for forming vascular-like channels involves liquid-in-liquid 3D printing utilizing two polymer solutions used as a printing ink and a matrix. Anionic polyacrylamide (APAM) is one of the polymer solutions and acts as the matrix material. Chitosan is the other polymer solution and acts as the printing ink. The chitosan printing ink is extruded through a print nozzle of a 3D printer onto the APAM matrix which covers the bottom of a petri dish while the nozzle is moved in a desired pattern for the channels. The chitosan and APAM polymer complexes self-assemble on the ink-matrix interface, locking chitosan polymers inside the matrix before they can spread and causing the formation of soft elastic membranous walls. The chitosan ink and APAM matrix can be removed after the polymer complex self-assembly. The printed chamber with membranous walls allows for liquid infusion to work as fluidic channels.
