Publication number: 20230149753Abstract: A foam production method includes mixing liquid nitrogen with a foaming material to produce foam. A gas is produced in situ from liquid nitrogen. As the ratio of the volume of the gas produced by gasification of liquid nitrogen to the volume of the liquid nitrogen is relatively high, when a large gas supply flow is needed to generate a large foam flow, a liquid nitrogen storage device of a small volume can be used instead of bulky air supply devices such as high-pressure gas cylinders, air compressors, air compressor sets and the like, reducing the volume of the air supply device. In addition, the liquid nitrogen used in foaming will release nitrogen gas after the foam blast, such that the nitrogen is also able to inhibit combustion on the surface of burning materials, accelerating the extinguishing of the fire.Type: ApplicationFiled: January 19, 2023Publication date: May 18, 2023Applicants: CHINA PETROLEUM & CHEMICAL CORPORATION, CHINA PETROLEUM & CHEMICAL CORPORATION QINGDAO RESEARCH INSTITUTE OF SAFETY ENGINEERINGInventors: Shanjun MU, Chunming JIANG, Weihua ZHANG, Quanzhen LIU, Xuqing LANG, Xiaodong MU, Lin WANG, Jingfeng WU, Longmei TAN, Zuzheng SHANG, Rifeng ZHOU, Jianxiang LI, Hui YU

Publication number: 20210188649Abstract: A carbon-based porous material microscopically exhibiting a three-dimension 1 cross-linked net-like hierarchical pore structure, a specific surface area of 500˜2,500 m2/g and a water contact angle greater than 90°. The surface of the carbon-based porous material has a through hierarchical pore structure with mesopores nested in macropores and micropores nested in mesopores, the content of mesopores is high, and there are more adsorption activity sites exposed on the surface of the material, so that the diffusion path for organic gas molecules in the adsorption process is shortened. At the same time, the absorption and desorption rates may also be accelerated and the desorption temperature may be lowered. Furthermore, benefits result for solving the desorption and recovery problems of organic gas molecules. Moreover, the defects of ordinary porous carbon materials being easily hygroscopic, having a weakened capacity to adsorb target gas molecules in a humid environment, etc. are further effectively solved.Type: ApplicationFiled: January 28, 2021Publication date: June 24, 2021Inventors: Shanjun MU, Yuxin ZHAO, Chunming JIANG, Quanzhen LIU, Weihua ZHANG, Lin WANG, Shucai ZHANG, Xiaodong MU

Patent number: 8189644Abstract: A laser assembly and method of operating the assembly are described in which a pump beam is directed through an end-pumped solid-state laser gain medium four or more times. The pump beam is directed at a slight angle through a first end of the medium, reflects off the inner surface of the second, opposite end (to form a “V”), and then reflected by an external or integrated mirror back through the first end and off the inner surface of the opposite end again (back through the “V”).Type: GrantFiled: April 26, 2010Date of Patent: May 29, 2012Assignee: Onyx Optics, Inc.Inventors: Xiaodong Mu, Helmuth E.

Publication number: 20120110820Abstract: Adhesive-free bond non-linear optical (NLO) components, devices and systems including one or more engineered quasi non-critical phase matched or contra-phase matched NLO crystal doublets. Such systems and devices advantageously increase the efficiency of NLO frequency conversion and improve beam quality. Devices are applicable to any uniaxial and biaxial NLO crystals in a wide range of wavelengths, e.g., from far ultraviolet to visible to far infrared. Devices employing engineered AFB NLO components according to certain embodiments include any conventional frequency converting architectures. Systems and methods are also provided to unambiguously determine and correct walk-off for any arbitrary uniaxial and biaxial crystal orientation.Type: ApplicationFiled: January 13, 2012Publication date: May 10, 2012Applicant: ONYX Optics, Inc.Inventors: Xiaodong Mu, Helmuth E.
