Small, EarlyView.ABSTRACT Active and stable electrocatalysts are critical for sustainable hydrogen production, particularly for high‐current‐density water electrolysis and specialized applications like seawater splitting. However, most water‐splitting electrocatalysts show limited activity at high current densities and poor long‐term stability, making it difficult to ...

Femtosecond laser microstructuring of zirconia dental implants
Journal of Biomedical Materials Research Part B: Applied Biomaterials, 2010 AbstractThis study evaluated the suitability of femtosecond laser for microtexturizing cylindrical zirconia dental implants surface. Sixty‐six cylindrical zirconia implants were used and divided into three groups: Control group (with no laser modification), Group A (microgropored texture), and Group B (microgrooved texture).

Future prospects of zirconia for oral implants —A review
Dental Materials Journal, 2020 Zirconia have been applied to dental implants as well as fixed dental prostheses due to their mechanical, esthetic and biocompatible performance. Moreover, they offer an advantage over titanium (Ti) implants, in that there is no risk of discoloration or hypersensitive reaction with allergy.
