Application of the smoothed particle hydrodynamics (SPH) method to simulation granular materials under large deformation is presented. The Drucker–Prager constitutive model with nonassociated flow rule implemented in SPH formulations a continuum framework. developed validated by experiments on collapse two-dimensional columns as reported literature. Simulations three-dimensional axisymmetric sand various aspect ratios are also conducted. Numerical results pattern, final runout distance,...
Oxygenated volatile organic compounds (OVOCs) and secondary aerosol (SOA) formation potential of ambient air in Guangzhou, China was investigated using a field-deployed oxidation flow reactor (OFR). The OFR used to mimic hours weeks atmospheric exposure hydroxyl (OH) radicals within the 2–3 min residence time. A comprehensive investigation on variation VOCs OVOCs as function OH is shown. Substantial acids nitrogen-containing OVOC species were observed. Maximum SOA observed following 1–4...
Abstract This case study describes how electron-beam melting, a powder bed additive manufacturing technology, helped reduce the cost and material scrap associated with production of Ti-6Al-4V brackets used in hot side engine on Lockheed Martin's Joint Strike Fighter.
Renewable energy-driven electrochemical CO2 reduction has emerged as a promising technology for sustainable future. However, achieving efficient production of storable liquid fuels at ampere-level current densities remains significant hurdle in the large-scale implementation electroreduction. Here we report novel catalytic electrode comprising chlorine-doped SnO2 nanoflowers arrayed on exterior three-dimensional nickel hollow fibers. This demonstrates exceptional electrocatalytic performance...
We report the position reconstruction methods and surface background model for PandaX-4T dark matter direct search experiment. This work develops two algorithms: template matching (TM) method photon acceptance function (PAF) method. Both determine horizontal of events based on light pattern secondary scintillation collected by sensors. After a comprehensive evaluation resolution, uniformity, robustness, PAF was selected reconstruction, while TM employed verification. The achieves bulk event...
Dy films, deposited on the surface of sintered Nd–Fe–B magnets by magnetron sputtering, were employed for grain boundary diffusion source. High coercivity successfully prepared. Effects sputtering power and processes (GBDP) microstructure magnetic properties investigated in detail. The dense uniform films beneficial to prepare high GBDP. maximum value 1189 kA m−1 could be shown, which was an amplification 22.3%, compared with that as-prepared magnet. Furthermore, improved remanence energy...
The High Energy X-ray telescope (HE) on-board the Hard Modulation Telescope (\textit{Insight}-HXMT) can serve as a wide Field of View (FOV) gamma-ray monitor with high time resolution ($\mu$s) and large effective area (up to thousands cm$^2$). We developed pipeline search for Gamma-Ray Bursts (GRBs), using traditional signal-to-noise ratio (SNR) method blind coherent targeted search. By taking into account location spectrum burst detector response, is more powerful unveil weak sub-threshold...
The tensile strength evolution and strengthening mechanism of Cu-Fe in-situ composites were investigated using both experiments theoretical analysis. Experimentally, the with a cold deformation strain was studied model alloys Cu-11Fe, Cu-14Fe, Cu-17Fe, effect on matrix Cu-3Fe Cu-4.3Fe. related to microstructure mechanisms. Based these experimental data insights, mathematical established for dependence strain. For low strains, mainly work hardening, solid solution, precipitation...
An interesting ensemble of NiOx@Au (i.e. 20–30 nm gold particles partially covered with very small NiOx segments) were clearly identified to be highly active for the low-temperature gas-phase oxidation alcohols. On such ensembles, large amounts Ni2O3–Au+ hybrid sites defined, taking a step closer identifying activity. By their nature, Ni2O3 specimens not only promote formation Au+ ions and stabilize them but also act as an oxygen supplier transfer species onto react alcohol.
Infrared transmitting glass–ceramics based on the selected glass of 65GeSe 2 –25Ga Se 3 –10CsI were obtained by a two‐stage heat‐treatment method. Results X‐ray diffraction and scanning electronic microscopy indicated that droplet‐like nanoparticles containing cubic Ga 2−δ Ge δ crystals are homogeneously generated in whole glass–ceramic process is composed phase separation, nucleation, crystal growth. Evolutions optical mechanical properties versus annealing time at first‐stage heat...
A gradient nano-grained (GNG) surface layer is produced on a bulk coarse-grained Cu by means of mechanical grinding treatment. Homogeneous grain coarsening induced deformation observed in the GNG under tensile tests at both 300 K and 123 K. The concurrent during proven to be also thermally activated, because extent less significant than K, although higher flow stress achieved During subsequent storage 258 after tests, no obvious change can found for size deformed In contrast, widespread...
