A pulsed Nd:YAG laser ablation of FeS in water and ethanol produces FeS-derived colloidal nanoparticles which absorb onto immersed porous ceramic substrates and create solar-light photocatalytic surfaces. The stability, size...

Highly polymorphic cobalt sulfide represents attractive material because of its unique electronic, optical, magnetic, mechanical and catalytic properties. Pulsed laser irradiation of a solid CoS 2 target results in ablation and deposition of thin films on Ta and Cu substrate, which were analyzed using scanning electron microscopy, Raman and FTIR spectroscopy, X-ray photoelectron spectroscopy, high resolution electron microscopy and electron diffraction. These complementary analyses revealed that the film on Ta consists of the parent cubic CoS 2 whereas the film on Cu exhibits a multiphase structure containing the cubic CoS 2 and cubic Co 2 CuS 4 . The ternary species is known as an active electrode material with relatively high en-[a] New
