Patent number: 11958946Abstract: A method for preparing a carbon nano tube/polyacrylic acid hydrogel, a product and an application thereof are provided. The method includes: oxidizing a carbon nanotube into a carboxylated carbon nanotube, thereafter performing in-situ polymerization with acrylic acid, sodium hydroxide, ammonium persulfate, triethanolamine and N, N-methylenebisacrylamide to obtain a carbon nanotube/polyacrylic acid hydrogel. The hydrogel has a uniform porous structure, facilitating a rapid transmission and supply of water. The carbon nanotubes in the hydrogel are of an array structure, achieving a full absorption of solar energy to realize a high-efficiency photothermal conversion. The gel is attached to a sponge base to obtain a solar-powered carbon nano tube/polyacrylic acid hydrogel steam generator for the photothermal conversion. The steam generator is used for solar seawater desalination, but can improve evaporation rate and evaporation efficiency.Type: GrantFiled: June 8, 2023Date of Patent: April 16, 2024Assignee: GUANGDONG OCEAN UNIVERSITYInventors: Lefan Li, Chengpeng Li, Jingyuan Guo, Di Wang, Chengyong Li, Wenhua Wang, Zhang Hu, Sidong Li

Patent number: 9708224Abstract: The invention proposed a novel hot pressing flowing sintering method to fabricate textured ceramics. The perfectly 2-dimensional textured Si3N4 ceramics (Lotgering orientation factor fL 0.9975) were fabricated by this method. During the initial sintering stage, the specimen flowed along the plane which is perpendicular to the hot pressing direction under pressure, through the controlling of the graphite die movement. The rod-like ?-Si3N4 nuclei was easily to texture during the flowing process, due to the small size of the ?-Si3N4 nuclei and the high porosity of the flowing specimen. After aligned, the ?-Si3N4 grains grew along the materials flowing direction with little constraint. textured Si3N4 ceramics fabricated by this invention also showed high aspect ratio. Compared to the conventional hot-forging technique which contained the sintering and forging processes, hot pressing flowing sintering proposed is simpler and lower cost to fabricate textured Si3N4.Type: GrantFiled: August 10, 2015Date of Patent: July 18, 2017Assignees: DONGGUAN SOUTH CHINA DESIGN AND INNOVATION INST., GUANGDONG UNIVERSITY OF TECHNOLOGYInventors: Shanghua Wu, Qiangguo Jiang, Weiming Guo, Shangxian Gu, Maopeng Zhou, Wei Liu, Lixia Cheng, Bo Wang, Chengyong Wang, Qimin Wang

Patent number: 9290847Abstract: The present invention provides an Al2O3 coated Si3N4 cutting tool comprising a Si3N4 based substrate body and a coating layer on the substrate body, wherein the coating layer has at least one Al2O3 coating layer consisting of amorphous Al2O3 or nanocrystalline ?-, ?-, or ?-Al2O3. The hard and wear resistant refractory coating is deposited onto the Si3N4-based substrate body by reactive sputtering using bipolar pulsed DMS technique or dual magnetron sputtering method at substrate temperatures of 300-700° C. During the deposition, preferably, the substrate temperature is controlled to achieve the desired crystal structure of the coating. To form amorphous Al2O3 coating on the surface of the substrates, the deposition temperature can be controlled from 300 to 500° C.; on the other hand, to form nanocrystalline ?-, ?-, or ?-Al2O3, the deposition temperature can be controlled in the range of 500-700° C.Type: GrantFiled: December 23, 2013Date of Patent: March 22, 2016Assignee: GUANGDONG UNIVERSITY OF TECHNOLOGYInventors: Shanghua Wu, Ying Long, Qimin Wang, Chengyong Wang

Publication number: 20140090411Abstract: A heat pump system, including a main heat pump system and a directly expanded strong cool-heat radiation plate provided on the building surface and serving as the terminal of the main heat pump system. The directly expanded strong cool-heat radiation plate enables refrigerant in the main heat pump system to circulate therein. Since the heat pump system of the present application adopts the directly expanded strong cool-heat radiation plate as the terminal of the main heat pump system, refrigerant in the main heat pump system may exchange heat with air by means of the directly expanded strong cool-heat radiation plate directly, instead of secondary heat exchange of the refrigerant loop and the water circulation loop, thereby reducing loss in intermediate heat exchange, improving the heat exchange efficiency and heat utilization, and omitting the circulating pump for water circulation. An air-conditioner with the heat pump system is further disclosed.Type: ApplicationFiled: October 30, 2013Publication date: April 3, 2014Applicants: GUANGXI UNIVERSITY, GUANGXI JUNFUHUANG GROUND SOURCE HEAT PUMP CO., LTDInventors: Yingning HU, Biao LI, Jun LIN, Chengyong WANG
