Obtaining of zirconium silicate materials of aerogel type from aqueous solutions of Na2SiO3 and ZrOCl2 salts

open access: yesХімія, фізика та технологія поверхні, 2020
Aerogels are gels in which the liquid phase is completely replaced by a gaseous one. They form a new class of solids with a very low density, a large specific surface area and high porosity, which opens up wide possibilities for their practical ...

Sorption isotherms and isosteric heats of sorption of Malaysian paddy [PDF]

open access: yesJournal of Food Science and Technology, 2012
Understanding the water sorption characteristics of cereal is extremely essential for optimizing the drying process and ensuring storage stability. Water relation of rough rice was studied at 20, 30, 40 and 50 °C over relative humidity (RH.) between 0.113 and 0.976 using the gravimetric technique.

Catalytic Production of Levulinic and Formic Acids from Fructose over Superacid ZrO2–SiO2–SnO2 Catalyst

open access: yesColloids and Interfaces, 2022
Catalytic conversion of fructose to levulinic and formic acids over tin-containing superacid (H0 = −14.52) mixed oxide was studied. Mesoporous ZrO2–SiO2–SnO2 (Zr:Si:Sn = 1:2:0.4) was synthesized by the sol–gel method.
