DOI: 10.1002/smll.202405123
Abstract: Void-free perovskite films with oriented large grains are considered good performance. However, contradictory requirements on solvent volatilization arise that the growth of large grains requires slow volatilization while the residual solvent problem, which leads to… read more here.

DOI: 10.1080/21663831.2025.2498647
Abstract: Micro-texture design of hard-/soft-oriented grains improves Mg alloys' mechanical properties, while strength-ductility trade-off persists due to insufficient early-stage strengthening from soft-oriented grains and later-stage strain coordination in hard-oriented grains. Here, a TD-spread basal-textured dilute Mg-1.27Al-0.38Ca-0.45Mn… read more here.
