Modified Titanium Dental Implants: The Current Progress of Soft‐Tissue Integration Methods

Advanced NanoBiomed Research, EarlyView.
Dental implants are an established solution for tooth loss, yet achieving soft tissue integration (STI) around the transmucosal region remains a challenge. The natural tooth–gingiva interface is poorly replicated on titanium implants. This review explores surface modification strategies, ranging from surface chemistry and topography to biological ...

Supercritical Antisolvent Process to Produce Cerium Oxide Nanoparticles as a Support for High-Activity Platinum Catalysts

Chemical Engineering Transactions, 2017
Cerium acetylacetonate (Ce(acac)3) was precipitated from methanol (MeOH) using supercritical antisolvent process (SAS). The precursor was, then, calcined obtaining the cerium oxide (CeO2).

A narrow bandgap Schottky heterojunction Fe2N/CeO2 microneedle triggering sonodynamic reactive oxygen species storm for drug‐resistance‐free skin fungal infection

BMEMat, EarlyView.
Inorganic sonosensitizers suffer from inefficient electron‐hole separation, rapid recombination, and wide bandgaps in anti‐fungal applications. We propose MN@Fe2N/CeO2 to directly eliminate fungi without drug resistance. Combining semiconductor CeO2's advantages with Fe2N's high work function and activity enables efficient Schottky heterojunctions ...
