[en] Dynamic compression using lasers has become an important technique in high-pressure science. Lasers offer many advantages, including access to the most extreme pressures available in the laboratory, excellent control of the time-dependent drive, variable drive area, small sample size, and rapid shot rate. Large lasers capable of reaching pressures in the TPa regime have been built around the world, and several FEL and synchrotron x-ray light sources have or are planning laser drivers. These lasers are becoming true user-access facilities aiming to be accessible to a broad user community. I will describe several common experiments and diagnostics used in laser-compression experiments, highlight some of our group’s recent results, and offer my vision for the future of the field. The primary attribute of the laser-driven compression platform lies in the extreme flexibility of stress-loading paths and compression geometries available. Single shock, multiple shock, pure ramp, various shock-ramp combinations, unsupported shocks, and purposefully-unsteady shocks are all finding applications in laser-compression experiments. Monochromatic or broad-band x-rays, generated with exquisite timing precision by the laser itself, are employed for a variety of diffraction, radiography, absorption, and phase-contrast imaging experiments. Using standard diagnostics, laser platforms are used to measure the, stress-strain EOS, melting, phase-transitions, Gruneissen-parameter, sound-speed, crystal-structure, temperature, and non-equilibrium dynamics of compressed materials. Near-term progress for the laser-compression platform involve the inclusion of impressive x-ray probe sources. Several X-ray FELs and 3^rd and 4^th generation synchrotrons are installing ~100 J shaped-pulse laser drivers on specialized beam lines. Perhaps the most exciting advance in laser drive technology is the reduction of shot repetition rate for TPa-class experiments from 1 every 0.5 to 12 hours to shots every few minutes of even shots operating at 10 Hz using high-energy class diode-pumped solid-state lasers (HEC-DPSSL). These advances require a paradigm shift from very-expensive, drive-limited target designs, to rapid-fire, low-cost, easily-manipulated targets. This emerging paradigm will be coupled to a shift from exclusive-access facilities, to a broad-based, user-centric future for laser-driven compression experiments. The future for laser-driven compression using economical drivers, targets, and probes accessible to a broad range of users is very bright.

[en] CFD-DEM approach is applied to investigate circulation motion of particles in a mono-disperse system under both dry and wetting conditions. Good agreement between simulation results and measurement data is observed, in terms of cycle time and residence time in dry condition. The deposition of droplets on the particle surface is modeled by a Monte Carlo approach. The influence of cohesion forces on the macroscopic particle circulation is discussed. In addition, information about coating coverage, the layer thickness and particle size distribution can be predicted by this integrating approach. (Author)

[en] The soft fabric is prone to burr, fold, enfold and blur, which poses a great challenge to the accuracy of visual edge detection and localization of the autonomous loading and unloading material system of garment robot. In order to overcome the above problems, it proposes an adaptive edge localization method based on double filtering in this paper, which can be used to guide the garment robot to achieve grasping of soft fabric automatically. Firstly, the Gauss filtering and morphological filtering are used to smooth the image, and then it calculates the canny adaptive threshold based on the edge gradient information and detect the edge, finally it locates the coordinates of edge feature extracted. The experiment results show that the method is effective accuracy greater than 96%and robust tested on the real data sets composed of soft fabric. The method has good application value for the autonomous loading and unloading operation of the garment robot and has positive significance for the construction of the intelligent garment factory.

[en] The primary decomposition product (TKX-50-M) of dihydroxylammonium 5,5′-bistetrazole-1,1′-diolate (TKX-50) was obtained under adiabatic condition by using accelerating rate calorimeter (ARC). Meanwhile, diammonium 5,5′-bistetrazole-1,1′-diolate (ABTOX) was confirmed as the main component of TKX-50-M. Specific heat capacity of TKX-50-M and ABTOX was studied from 0 to 45 °C. In addition, the thermal decomposition of TKX-50-M and ABTOX was studied under adiabatic condition. The experiment results revealed that TKX-50-M were more thermal sensitive than ABTOX. Furthermore, ABTOX exhibited much violent than that of TKX-50-M during decomposition.

[en] In this work, novel Ag₃PO₄/PbBiO₂Br composites have been successfully prepared by one-step chemical precipitation method. The photocatalytic activity of as-prepared photocatalyst was evaluated by decomposing methyl orange (MO) dye under visible light irradiation. The results showed that the Ag₃PO₄/PbBiO₂Br composites exhibited excellent degradation efficiency for MO compared to pure Ag₃PO₄ and PbBiO₂Br. The enhanced photocatalytic activity of the Ag₃PO₄/PbBiO₂Br composites can be ascribed to the effective separation of photo-generated electron-hole pairs. Moreover, based on these experiment results, a reasonable mechanism was also proposed to explain the photocatalytic activity of Ag₃PO₄/PbBiO₂Br composites. (paper)
