Aluminosilicates compacts by alkoxide route: influence of Ba addition
Cerâmica, 1999 The sol-gel route was employed to obtain three different powders with the stoichiometric composition corresponding to mullite (3 Al2O3.2SiO2): (i) commercial alumina and silica from sol-gel, (ii) alumina and silica by alkoxide partial hydrolysis, (iii ...

Precursor type affecting surface properties and catalytic activity of sulfated zirconia [PDF]
Acta Periodica Technologica, 2007 Zirconium-hydroxide precursor samples are synthesized from Zr-hydroxide, Zr-nitrate, and Zr-alkoxide, by precipitation/impregnation, as well as by a modified sol-gel method. Precursor samples are further sulphated for the intended SO4 2- content of 4 wt.%

Potentialities of the sol-gel route to develop cathode and electrolyte thick layers Application to SOFC systems [PDF]
, 2008 In this work, we report the potential of sol–gel process to prepare cathode and electrolyte thin and thick layers on anodic NiO-YSZ supports which were also made from powders prepared by sol–gel route.

Biocatalytic Regioselective C‐Formylation of Resorcinol Derivatives
Angewandte Chemie, EarlyView.An acyltransferase from Chromobacterium sphagni (CsATase) was identified that catalyzes the regioselective formylation of resorcinol substrates. The formylation of substituted resorcinol derivatives yielded mono‐formylated products with up to 99% conversion and up to 74% isolated yield.

Use of metal catalysts bearing Schiff base macrocycles for the ring opening polymerization (ROP) of cyclic esters [PDF]
, 2017 © 2017 by the authors. Schiff base macrocycles are emerging as useful scaffolds for binding two or more catalytic metals in close proximity. Such coordination chemistry allows for the evaluation of potentially beneficial catalytic cooperative effects. In
