Abstract: The present disclosure belongs to the technical field of electrocatalytic materials, and provides a graphitic carbon-doped and mixed crystal-type titanium dioxide nanotube composite for electrocatalysis, and a preparation method and use thereof. The composite for electrocatalysis includes a titanium substrate and a titanium dioxide nanomesh deposited on the titanium substrate, where the titanium dioxide nanomesh is woven from titanium dioxide nanowires; the titanium dioxide nanowires include anatase-type titanium dioxide nanowires and rutile-type titanium dioxide nanowires. The mixed crystal-type titanium dioxide phase improves a catalytic activity of the composite for electrocatalysis; meanwhile, the titanium dioxide nanowires are further loaded with graphitic carbon particles to improve an overall conductivity of the composite for electrocatalysis.

Abstract: Provided herein are improved performance high vinyl block copolymer compositions. The compositions may include a block copolymer and a polyolefin. The block copolymer may have a microstructure characterized by a vinyl content of equal to or greater than about 60%. The block copolymer may be a styrenic block copolymer. The polyolefin may include a polypropylene. Additional additives may be optionally added to the composition depending on the end-use application. The compositions may find utility in the preparation of various articles such as medical products including sterilized tubing, bags, and the like, films and injection molded articles.

Abstract: Disclosed is a parallel digging, mining and filling operation coal mining method, in which a stope haulage roadway, stope branch roadways, and two-winged adits are arranged in a stope. The stope haulage roadway and the stope branch roadways serve as haulage passages, and coal mining work is carried out in the two-winged adits. All two-winged adits are mined sequentially and filled timely, and coal mass that has not been mined or two-winged adits that have been filled always exist at the two sides of the two-winged adit that are being mined, to support and control the roof. The two-winged adits can be mined without support or with less supports by controlling the length of the two-winged adits and the number of two-winged adits filled in one time, whereupon pillar-free mining can be realized.

Abstract: A transportation main roadway and stope branch roadways are arranged by adopting a wangeviry coal mining method. A plurality of stope branch roadways are divided into multiple mining stages, based on which the stope branch roadways are skip-mined; and coal pillars are not reserved among the stope branch roadways. The transportation main roadway is a main transportation channel, and the stope branch roadways are coal mining roadways. All the stope branch roadways are sequentially stoped in a skip-mining manner according to the designed mining sequence and are sequentially and timely filled. The coal never stoped or the filled stope branch roadways is/are used as supports for controlling roofs at the two sides of the stope branch roadways, and the stope branch roadways are sequentially stoped according to a plurality of mining stages, and finally the coal pillar-free mining is realized.

Abstract: A device and method of using infrared radiation to observe coal rock fracture development processes, for use in experiments to monitor coal rock fracture development using infrared radiation comprises three telescopic box bodies sleeved together. An infrared thermal imager connected to a computer is arranged at the front end of the telescopic box bodies, and a light-blocking plate is installed on a rear end. The distance between a coal rock test block and a lens of the infrared thermal imager can be freely adjusted via the three telescopic box bodies. The telescopic box bodies are installed on a rock press, and a loading test is performed on the coal rock test block.

Abstract: A water-preserved-mining roof-contacted filling method for controlling fissure of overlying strata and surface subsidence. The method is suitable for controlling fissure of overlying strata and surface subsidence in water-preserved-mining of a mine. A sensor is mounted at the top of a goaf of a filling working face where water-preserved-mining is carried out, and a filling body that is filled is monitored through a stress display device so as to determine whether the goaf is roof-contacted or separated. When the filling body is separated after roof-contacted, the goaf is filled for the second time so as to be roof-contacted fully, so that the purpose of controlling fissure of overlying strata and surface subsidence can be achieved, and protective mining of water resources of the mine can be realized at last. The method is simple and targeted, and has strong operability and high efficiency.
