Influence of Backside Surface and Subsurface Damage in Gallium Nitride Wafers on Facet Quality and Violet‐Emitting Laser Diode Performance

physica status solidi (a), Volume 223, Issue 14, 22 July 2026.
Backside thinning techniques critically influence GaN laser performance. Compared to lapping, grinding reduces subsurface damage depth fivefold and lowers wafer bow, while mechanical polishing eliminates subsurface damage entirely. These improvements directly translate to smoother cleaved facets and a nearly 40% reduction in laser threshold current ...

Effect of C5a Receptor Antagonist on the Osteogenic Differentiation of Dental Pulp Stem Cells

Clinical and Experimental Dental Research, Volume 12, Issue 3, June 2026.
ABSTRACT Objective Complement component 5a (C5a) binding to its receptor (C5aR) can mediate pro‐inflammatory immune responses, which impairs osteogenic differentiation of dental pulp stem cells (DPSCs). The present study aimed to evaluate the regulatory effect of C5aR antagonist (W54011) on the osteogenic differentiation of DPSCs in an in vitro ...
