In this paper we report, for the first time, the direct incorporation of a heteropolyacid (HPA)
with Wells-Dawson structure during the synthesis of silica by the sol–gel technique, in acidic …

This review describes the synthesis and characterization of inorganic materials containing
polyoxometalates encapsulated in oxide matrices. Examples illustrating key aspects in terms …

Kinetic models were developed to describe the esterification reaction of lauric acid and
ethanol over heterogeneous catalysts, which is a reaction of special interest in the biodiesel …

Solid acid catalysts based on the direct incorporation of the vanadium Keggin
heteropolyacid (PMo11V) structure during the synthesis of silica by the sol–gel technique, in …

Environmental implementation of novel composite materials comprising potassium

The Cs salt of molybdophosphoric acid Cs2. 5H0. 5PMo12O40 (CsHPM) was supported on
SBA-15 in the concentration of 20, 30 and 40wt.% loadings. Because Cs acid salts are …

Fungal growth in damp surfaces of water-damaged buildings is an increasing problem
around the world, which has adverse effects on both people's health and buildings. By bio …

The current study reports the synthesis, characterization and catalytic activity of
tungstophosphoric acid (HPW) and its potassium salts (KH 2 PW and K 3 PW) supported on …

This work aimed to improve the oxygen transfer mass coefficient (kLa) in mixing reactors,
first evaluating the effect of agitation and aeration and then evaluating the influence of the …

CL-20, a high-energy material with a cage-like structure, is considered the most powerful
explosive today. It is usually prepared via nitration with concentrated nitric and sulfuric acid …
