Abstract Nanofibers prepared by electrospinning technology possess large specific surface area and adjustable fiber diameter. Zein is a hydrophobic plant protein that can interact with pollutants in the air. In this work, using polyvinyl alcohol (PVA) as auxiliary spinning polymer, zein based nanofiber materials are for air filtration varying zein/PVA ratio well alcoholysis degree. With increase of content, diameter nanofibers decreases gradually, PVA low degree exhibit better...
This work presents quantum key distribution protocols (QKDPs) to safeguard security in large networks, ushering new directions classical cryptography and cryptography. Two three-party QKDPs, one with implicit user authentication the other explicit mutual authentication, are proposed demonstrate merits of combination, which include following: 1) against such attacks as man-in-the-middle, eavesdropping replay; 2) efficiency is improved contain fewest number communication rounds among existing...
This research aimed to detect the defects of anchoring agents’ empty slurries in anchor support. The influence on propagation law stress waves was comprehensively investigated using laboratory tests, theoretical calculations, and other methods. characteristic modal components with symmetry periodicity laws were extracted by adopting a variable decomposition (VMD) signal method. It found that bottom reflection time had an inverse function relationship length anchorage flaw. average speed wave...
In response to the complex unstructured environment of coal mines, a design scheme for variable wheel diameter robots is proposed. Based on gear, connecting rod and sliding rail mechanism, with was designed. Through change in robot, obstacle-crossing ability terrain adaptation robot were improved. The kinematic model single established variation rule radial length analysed. kinematics whole vehicle established, motion state under different driving speeds RecurDyn software, turning, process...
Abstract In coal mining roadway support design, the working resistance of rock bolt is key factor affecting its maximum load. Effective improvement great significance to support. Based on bolt’s tensile characteristics and surrounding deformation, a mechanical model for calculating was established solved. Taking 17102 (3) face at Panji No. 3 Coal Mine China as research site, with quadrilateral section roadway, influence pretension anchorage length high-strength ordinary bolts in middle...
In order to study the energy storage and sound emission characteristics of rocks under different water content, uniaxial compression test, cyclic loading, unloading test were carried out using RMT-150B rock mechanics system DS5 acoustic system. The results show that total strain saturated samples area hysteresis loop are largest in same period number, which indicates presence can reduce elastic limit samples, making very easy deform even damage. Acoustic tests damage water-bearing is small....
With the analytical grade Ce(NO3)3·6H2O, Sm(NO3)3·6H2O, and Na2CO3 as starting materials, Sm0.2Ce0.8O1.9(SDC)/Na2CO3 nanocomposite electrolytes were prepared through a rare-earth/sodium carbonate complex precipitation, prefiring, sintering operations. The phase components microstructures studied characterized by XRD, FESEM, TEM, TG-DSC. In particular, interfacial interactions between phases of SDC crystallites amorphous deliberately probed Raman infrared spectroscopies. It has been found...
Traditional rock bolt inspection methods are destructive and limited. Non-destructive testing (NDT) based on the stress wave method can realize a fast convenient quality detection of bolts. To verify effectiveness wave-based anchor NDT method, multi-functional experimental bench was customized basis bench-pull tension machine. Stress waves be generated by applying axial loads bolts then collected using non-destructive tester. The VMD decomposition Hilbert–Huang signal processing were used to...
The nondestructive testing technique used to evaluate the quality of bolt support by detecting axial force is suitable for with a short construction time. For in state long time period, it may lead detection small only and ignore fact that has entered necking fracture stage, thus fail detect safety hazards Three sets parallel tests were conducted solve misjudgment results due reduction when was stage. Bolt deformation characteristics stress wave propagation bolts under tensile studied using...
