Extraction of Humic Acid from Lignite by KOH-Hydrothermal Method

Applied Sciences, 2019
Humic acid (HA) was extracted by a hydrothermal method from Huolinhe lignite from Inner Mongolia. The effects of the alkali-to-carbon mass ratio, water-to-coal mass ratio, reaction temperature, and reaction time on the HA yield were investigated.

Bioactivity evaluation of nanosized ZnFe2O4 fabricated by hydrothermal method

Processing and Application of Ceramics, 2021
In this study, we investigated the structural, microstructural, magnetic and cytotoxic properties of encapsulated ZnFe2O4 nanoparticles. The nanoparticles were synthesized using the microwave-assisted hydrothermal method and their surfaces were silanized and later encapsulated with poly-2-hydroxyethyl methacrylate (PHEMA).
