The analysis by scanning-electron microscopy revealed that BiOCl photocatalysts made with urea and thiourea had irregular-like and rod-like shapes, respectively. The BiOCl photocatalyst synthesized with urea and thiourea degraded Methylene Blue (MB) by 90 % and 100 %, respectively, after 90 min under UV–VIS light. Interestingly, BiOCl photocatalyst made with thiourea degraded completely MB after only 60 min under solar light. Later, the BiOCl photocatalyst was supported on recycled rubber (taken from bicycle tires) and this rubber/BiOCl (R/BiOCl) composite produced 100 % degradation for MB after 90 min of photocatalytic reaction. BiOCl powder synthesized with thiourea also degraded totally Rhodamine B (RhB) dye (after 90 min using UV–VIS light and after 10 min using sunlight). The R/BiOCl composite degraded 100 % of RhB after 120 min. Thus, the R/BiOCl composite produced slower dye degradation, but it was easily removed (manually) from the clean water. BiOCl synthesized with thiourea produced the highest photocatalytic performance because: i) it had the highest absorbance in the UV–VIS range and ii) it had the highest content of defects, which promoted the photocatalytic activity. In fact, BiOCl made with thiourea induced the highest mineralization of carbon (86 %) according to the TOC analysis. Additionally, the incorporation of Er and Yb ions into the BiOCl lattice facilitated the Up-conversion process under solar irradiation, enhancing the generation of electron-hole pairs, which in turn, incremented the photocatalytic degradation of MB and RhB dyes.

A study investigates the laser shock dynamic compaction (LSDC) behavior of randomly distributed nano Al-Cu powders. The aim was to investigate the microstructural evolution and densification of randomly distributed nano Al-Cu powders during LSDC and to assess the effect of varying nano Cu content on the density and mechanical properties of Al-Cu nanopowder compacts. Using a self-developed LSDC platform, nano aluminum and nano copper powders were uniformly mixed in mass ratios of 5 %, 10 %, and 15 %, producing compacts with a density of 95.36 %. A model was established via the Gurney energy equation to link laser energy to upper punch velocity, and the compaction response of the nanopowders at different velocities was simulated. Molecular dynamics (MD) modeling, constructed using Atomsk and LAMMPS software, closely represented actual conditions, allowing characterization of crystal structure changes, dislocation evolution, and other behaviors during laser shock compaction. Results indicated that increasing nano Cu content led to a gradual decrease in the microhardness of Al-Cu compacts. Across shock velocities from 500 to 1500 m/s, the material exhibited three stages: solid non-densification, solid densification, and liquid densification. The study quantified temperature distribution and dislocation density during laser shock, clarifying compaction mechanisms at various shock velocities.
