A Tyrosinase Inhibitor from a Nitrogen-Enriched Chemically Engineered Extract
(American Chemical Society, 2019-09)
The enzyme tyrosinase is involved in the biosynthesis of melanin and the enzymatic browning of fruits and vegetables, and therefore, its inhibitors have potential to treat hyperpigmentary disorders or to function as food ...
Olefin metathesis over tin-modified non-transition metal oxides
(Elsevier Science BvAmsterdamHolanda, 1999)
Influência dos óxidos de ferro na reação pozolânica da metacaulinita
(Universidade do Vale do Rio dos Sinos, 2021-12-20)
Pozzolans are materials that react with calcium hydroxide in the presence of water, forming secondary hydrated products and promoting gains in strength and durability in cementitious products. These materials must be ...

STRUCTURE, CHARACTERIZATION AND APPLICATION OF NI HYDROTALCITE AS SOLID BASE CATALYSTS FOR ORGANIC TRANSFORMATIONS
(Sociedad Chilena de Química, 2011)
Thermal analysis to assess pozzolanic activity of calcined kaolinitic clays
(Springer, 2014-04)
The use of calcined clays as partial replacement of cement is encouraged since it promotes the reduction of the green-house gas emission and the energy requirement of cement-based material, maintaining or enhancing the ...
Deoxygenation of m-cresol on Pt/gamma-Al2O3 catalysts
(Elsevier, 2013-09)
In this work the deoxygenation of m-cresol, used as a bio-oil model compound, was studied at atmospheric pressure, using Pt/γ-Al2O3 catalysts. The main products obtained in this system were toluene, benzene and methylcyclohexane. ...
Synthesis of Lamellar Structures of Magnesium (II), Aluminum (III) and Iron (III) Hydroxides Interchanged with Carbonate Ion through Precipitation in pH 11
(Univ Federal Mato Grosso Sul, Dept Quimica, 2018-01-01)
The synthesis of layered double hydroxides has been investigated aiming innumerous applications, mainly as adsorbent, catalyst and catalyst support materials, due their ability to adsorb anionic species and several aqueous ...
