  • Publication number: 20210008503
    Abstract: A method for preparation of conductive polymer/carbon nanotube (CNT) composite nanofiltration (NF) membrane and the use thereof. This conductive polymer/CNT composite NF membrane is obtained by polymerizing conductive polymer into a CNT membrane and then in-situ cross-linking with glutaraldehyde under acidic condition. The synthetic method for the conductive polymer/CNT composite NF membrane is simple and has no need of expensive equipment. The prepared membrane has controllable membrane structure and possesses superior electrical conductivity and electrochemical stability. The membrane can couple with electrochemistry for electrically assisted filtration. With the electrical assistance, the membrane can achieve improved ion rejection performance while retaining high permeability by enhancement of membrane surface charge density, which alleviates the permeability-selectivity trade-off.

  • Publication number: 20200122752
    Abstract: An energy absorbing device for subway vehicle includes a movable anti-climber, a fixed anti-climber, an energy absorbing honeycomb, at least one collapse tube, two sliding-groove assemblies and two guide sliding rails. As the first stage energy absorbing unit of the total structure, the energy absorbing honeycomb directly bears the collision impact transferred from the movable anti-climber. Through the deformation of the energy absorbing honeycomb itself under pressure, the collision kinetic energy transfers into internal energy of deformation and heat, thus realizing the energy absorbing buffering. As the second stage energy absorbing buffering unit, the at least one collapse tube further absorbs the collision energy, thus further buffering and protecting the underframe of the vehicle body, as well as ensuring that the impact energy performs a multistage and serial operation according to a predetermined direction and sequence, thereby ensuring the reliability of operation of the energy absorbing device.

  • Patent number: 10572275
    Abstract: Compatibility can be maintained when program code and pre-computed data associated with the program code are distributed in separate modules by using a data structure of key/value pairs comprising a dictionary. The dictionary can include a fixed part, a floating part and a version number. The version number in the dictionary can be used to determine if a dictionary for the program is current or outdated by comparing the dictionary version number and the version number associated with a dictionary layout in the current shared library. The dictionary can be rebuilt dynamically if the version number of the dictionary does not match the version number of the dictionary layout in the current shared library. The version number of the dictionary can be updated to the version associated with the layout version and the version pointer in the dictionary can be updated to point to the updated version number.

  • Publication number: 20200034528
    Abstract: An access control system includes a processor configured to provide a trusted execution environment isolated from a rich execution environment. A rich OS operates in the rich execution environment while a trusted OS operates in the trusted execution environment. An access monitoring module operates within the kernel of the rich OS and a trusted application operates in the trusted OS. The access monitoring module intercepts file requests directed at the file systems of the rich OS, and forwards the file requests to the trusted application. The trusted application then evaluates whether the file request is permitted and provides the access monitoring module with a response. The access monitoring module forwards the request to the file system only if the trusted application approves the request.

  • Patent number: 10179314
    Abstract: The invention, belonging to the field of membrane technology, presents a method for the high-throughput preparation of carbon nanotube hollow fiber membranes. This method contains three major steps. Firstly, the pristine carbon nanotubes (CNTs) are added into a mixture of concentrated nitric acid and sulfuric acid, which is then heated at 40˜80° C. for 0.5˜6 hours. Secondly, the surface-functionalized CNTs and polyvinyl butyral (PVB) are dispersed and dissolved, respectively, in organic solvents at a mass ratio of 1:0.2˜1:4˜8 to form homogeneous spinning solution, which is squeezed into water as shell liquid with water as core liquid at a flow rate ratios of 0.5˜5:1 through a spinneret to form CNT/PVB hollow fibers. Finally, the dry fibers are calcinated at 600˜1000 ° C. for 1˜4 hours in absence of oxygen to produce free-standing CNT hollow fiber membranes. The method involved in this invention is simple and highly efficient without needing any templates, expensive apparatuses and chemicals.
