YAG laser with tranexamic acid for 12 or 16 weeks did not produce consistent or significant effects on melasma severity.

A new catalyst structure offers a potential pathway toward more cost-effective hydrogen production via water electrolysis. The material centers on mesoporous single-crystalline Co 3 O 4 doped with ...

We demonstrate an all-fiber erbium-doped MO started by a compact and low-cost nanosecond passively Q-switched laser for the first time. The starting dynamics of this MO are experimentally investigated ...
