Effect of buffer layers and stacking faults on the reduction of threading dislocation density in GaN overlayers grown by metalorganic chemical vapor deposition
TL;DR: In this paper, the effect of the trimethylgallium (TMGa) flow rate in the GaN buffer layer on the optical and structural quality was studied, and high-resolution x-ray diffraction results showed that a high density of stacking faults is associated with threading dislocations.

ER stress attenuation by Aloe-derived polysaccharides in the protection of pancreatic β-cells from free fatty acid-induced lipotoxicity.
TL;DR: It was concluded that APs have a protective effect against type 2 diabetes by modulating obesity-induced ER stress in pancreatic β-cells by interfering with the FFA-induced activation of the PERK and IRE1 pathways as well as ROS generation.
