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.

Spin‐Crossover Confinement in Mesoporous Matrices Enables Tunable Porosity for Molecular Sensing

Advanced Materials Interfaces, EarlyView.
The integration of hierarchically organized porous frameworks with spin‐crossover nanodomains enables cooperative interactions across multiple length scales. This hybrid design merges dynamic molecular switching with tunable porosity, yielding materials whose structural and functional responses are actively modulated by confinement and guest uptake ...

High Yield Pulp Production by Modified Sulfite Process

JAPAN TAPPI JOURNAL, 1974
High yield pulp contains more lignin than the conventional chemical pulp. Therefore, refining and beating have little effect on fibrillation of pulp fiber, and the strength of paper therefrom is relatively low. Consequently, a process for making high yield pulp, which is easily refined and beaten to produce a high strength paper, have been desired ...
