Easy and green route towards nanostructured ZnO as active sensing material with unexpected H2S dosimeter-type behaviour [PDF]

, 2019
Nanostructured ZnO particles were prepared through a straightforward, quick and low\u2010temperature synthesis route involving coprecipitation of the metal precursor salts with oxalic acid, followed by hydrothermal treatment at 135 or 160 \ub0C.

Metals in the shell of Bathymodiolus azoricus from a hydrothermal vent site on the Mid-Atlantic Ridge [PDF]

, 2007
Specimens of the mussel Bathymodiolus azoricus were collected from Menez Gwen, a relatively shallow (850 m) hydrothermal vent field on the Mid-Atlantic Ridge. Each bivalve shell (n = 21) was individually cleaned by selective chemical.

Hydrothermal treatment of monodispersed titania.

Journal of Advanced Science, 1990
The monodispersed titania particles were prepared by the hydrolysis of titania tetra-ethoxide in a alcolic solution. The effect of heat treatment and hydrothermal treatment on the obtained monodipersed titania particles were examined by means of TEM, XRD, TG-DTA and BET.The obtained titanis particles was amorphous titanis was crystallized to anatase ...
