New proposal for sugarcane vinasse treatment by hydrothermal carbonization: An evaluation of solid and liquid products
(2020-01-01)
Vinasse is a residue of ethanol production from sugarcane. In view of the problems associated with its disposal, this study aimed to propose a treatment for vinasse by hydrothermal carbonization. The influence of temperature ...
Microwave-assisted hydrothermal synthesis of ZnO powders with different reagents
(2012-08-20)
In this work, zinc oxide powders were synthesized by microwave-assisted hydrothermal method in basic medium. These powders were analyzed by X-ray diffraction (XRD), Field-emisson gum scanning electron microscopy (FEG-SEM), ...

Chelating properties of humic-like substances obtained from process water of hydrothermal carbonization
(2021-08-01)
Recent studies have shown a new way of producing humic-like substances (HLS) from hydrochar prepared by hydrothermal carbonization of biomass. However, studies of HLS extracted from process water (PW) produced in hydrothermal ...
Microwave-assisted hydrothermal synthesis of nanocrystalline SnO powders
(Elsevier B.V., 2008-01-31)
Tin oxide (SnO) powders were obtained by the microwave-assisted hydrothermal synthesis technique using SnCl2 center dot 2H(2)O as a precursor. By changing the hydrothermal processing time, temperature, the type of mineralizing ...
Preparation of CeO2 by a simple microwave-hydrothermal method
(Elsevier B.V., 2009-03-09)
Cerium carbonate hydroxide (orthorhombic Ce(OH)CO3) hexagonal-shaped microplates were synthesized by a simple and fast microwave-hydrothermal method at 150 degrees C for 30 min. Cerium nitrate, urea and cetyltrimethylammonium ...

Growth kinetics of vanadium pentoxide nanostructures under hydrothermal conditions
(ElsevierAmsterdam, 2010-11)
The work reported here involved a study of the growth kinetics of V2O5nH2O nanostructures under hydrothermal conditions. The coarsening process of V2O5nH2O nanoribbons was followed by subjecting the as-prepared suspensions ...
