“…[ 32 ] This could be due to the increase in surface roughness of CuFLs after the formic acid treatment. [ 33 ] However, a real polymer has surface states within the energy gap due to chemical impurities, defects, and adsorbed molecules. [ 31,34 ] These surface states would decrease the experimental barrier height, compared with the theoretical barrier height.…”

Copper (Cu) is an attractive low‐cost alternative to silver or gold. However, it is susceptible to oxidation in air. Here, facile in situ regeneration of oxidized Cu flakes (CuFLs) for the synthesis of highly conductive non‐oxidized nanocomposites is reported. The oxidized CuFLs are regenerated into non‐oxidized CuFLs and Cu nanosatellite (CuNS) particles by formic acid‐aided in situ etching and reduction reaction in soft epoxy matrix. The average particle size of CuNS particles is only 3.3 nm with an interparticle distance of 2.7 nm. Furthermore, the negligible potential barrier height between Cu and epoxy dramatically increases the electrical conductivity (66 893 S cm−1) of the nanocomposite (Cu = 46 vol%) by more than three orders of magnitude. The thermal conductivity is also highest (85.1 W m−1 K−1), compared with Cu‐based nanocomposites in literature. The conductivities are invariant in air for more than 95 days. The simple scalable in situ regeneration of oxidized CuFLs may find immediate industrial applications.

“…The fragmentation process is far more complex than the relatively straightforward quasi‐static uniaxial tensile fracture and shear fracture. In recent years, the Mach reflection in an explosive charge has been widely used to achieve ultra‐high pressure or control the shape of the detonation wave, for further increasing the utilization factor of a high‐explosive charge [26, 27].

The collision of detonation waves is widely used in weapon design due to its ability to efficiently achieve an ultra‐high pressure region. This work discusses the dynamic fracture of metal rods under the collision of cylindrical detonations. In the experiments, the detonation wave collision is generated by detonating an explosive charge at its end position along two parallel initiation lines, which are detonated by a plane wave generator. The recovered metal rods were broken around their centers due to the superposition of detonation waves. A blue oxidation zone appeared at the fracture surfaces of steel rods in the contact zone under the charge, indicating the local existence of high temperatures. A finite element model was used to simulate and describe the dynamic fracture of metal rods caused by detonation wave collision. The three‐shock theory was used to examine the detonation wave collision. When the incidence angle was between 0° and 40°, the reflected shock wave pressure was approximately 2.1 times the CJ pressure. At an incidence angle of 44.84°, the ratio of Mach and CJ pressure reached a maximum of 3.1. The concentration degree of detonation pressure was developed to evaluate the superposition influence on the dynamic fracture of metal rods. The microstructure of fracture surfaces revealed that metal rods preferred shear fracture under high pressure concentration. With a low degree of pressure concentration, a brittle fracture may emerge. This research serves as a guide for designing and evaluating multimode warheads.

Monoclinic BiVO4 is extensively exploited in organic oxidation because of its appropriate valence band and remarkable catalytic activity. BiVO4 quantum dots not only have a high specific surface area and active sites for photocatalytic reactions, but can address the short carrier diffusion path problem. Herein, a Z‐scheme BiVO4 quantum dots/reduced graphene oxide/g‐C3N4 photocatalyst is constructed. Benefiting from the distinct BiVO4 quantum dots and layered g‐C3N4 sheets, the photocatalytic compound possesses a considerable light capture capability and surface area. The established Z‐scheme photocatalytic compound with a suitable electronic band structure and redox potential is integrated with a “synthesis and assembly” method. The sodium oleate surfactant plays an important role in the preparation of uniform BiVO4 quantum dots with a diameter of 3–6 nm. The optimized photocatalytic degradation experiments show that the ciprofloxacin and amoxicillin photocatalytic efficiencies are up to 92.2% and 70.7% in 1 h, respectively. It is shown that the improved photocatalytic activities involve in the prolonged lifetime of photogenerated electrons and fast carrier migration in the compound upon simulated sunlight exposure. Herein, a prospective stage for developing more Z‐scheme heterojunctions with excellent photocatalytic properties for antibiotic wastewater treatment and reproducible solar capture in photochemical energy conversion is offered.
