Crack Repair in Hydroxyapatite Bioceramics Using an Ultraviolet Ultrafast Laser
Advanced Materials Interfaces, EarlyView.The study proposes an ultrafast ultraviolet laser approach to repair hidden tooth cracks, which has been preliminarily validated on HAP. Moreover, this technique aims to strengthen the native enamel structure rather than introducing a foreign filling material.

Advanced Science, EarlyView.This work introduces a substrate‐independent, reagent‐free plasma strategy that forms radical‐rich interlayers for covalent hydrogel attachment without initiators or crosslinkers. The long‐lived radicals drive in situ gelation, creating robust, cytocompatible hybrid solid–hydrogel constructs across diverse substrates.
