Investigations on Microstructure and Mechanical Properties of AZ91 Alloy Processed by Single Pass Rolling with Varied Rolling Reductions

“…After further rolling, the microstructures of the alloys remained coarse, as shown in Figure 1c-f. Twinning was observed in the HR alloys processed by SPR with varied rolling reductions; as the H alloys have a poor plasticity, deformation twinning was activated to accommodate the applied rolling deformation [32]. When the rolling reduction increased, narrow localized deformation bands were also observed, as presented in the SEM image inset in Figure 1f.…”

Synergistic Strengthening of Dislocation and Heterodeformation Induced in Gradient Nanograined Copper Film: A Molecular Dynamics Study

“…The slope of the fitting curve indicates the strain strength gradient. [ 12,22 ] As increases, the slope of the curve gradually decreases. The decrease in grain size gradient weakens the strain strength gradient, thus impairing the extra strengthening effect of the GNG material.…”

“…After a series of experiments, they demonstrated that the nonuniform deformation of GS generates a large number of GNDs to accommodate the plastic strain gradient generated by the built‐in strength gradient. [ 21,22 ] It improves the strain hardening capacity of the gradient materials.…”

Triangular-shaped homologous heterostructure as photocatalytic H2S scavenger and macrophage modulator for rheumatoid arthritis therapy

“…45,46 In this case, it is feasible to incorporate the homogeneous metallic and semiconductor materials Ag and Ag 2 S into a single unit by the controlled sulfidation of Ag nanoparticles to form a hybrid heterostructure. 47 In this project, a polyethylene glycol/folic acid (PEG/FA)modified and resveratrol (RSV)-loaded Ag/Ag 2 S nanotriangle (Ag/Ag 2 S-PEG-FA/RSV NTs) homologous heterostructure was fabricated, and exhibited macrophage targeting for RA treatment via down-regulating the cytokine level through H 2 S scavenging and pro-inflammatory macrophage polarization modulation. 48,49 Firstly, under NIR irradiation, the photo-generated electrons and holes of the Ag/Ag 2 S heterostructure could simultaneously transform H 2 S into a sulfate anion for H 2 S elimination and ultimately suppress the MAPK/ICAM-1 pathway to inhibit inflammatory exacerbation.…”
