Enzymatic toxins from snake venom: structural characterization and mechanism of catalysis
(Wiley-Blackwell, 2011-12-01)
Snake venoms are cocktails of enzymes and non-enzymatic proteins used for both the immobilization and digestion of prey. The most common snake venom enzymes include acetylcholinesterases, l-amino acid oxidases, serine ...
Alternative raw materials to produce biodiesel through alkaline heterogeneous catalysis
(MDPI AG, 2019-08-15)
Recent research focuses on new biodiesel production and purification technologies that seek a carbon neutral footprint, as well as cheap, renewable and abundant raw materials that do not compete with the demand for food. ...
Structural requirements and reaction pathways in condensation reactions of alcohols on MgyAlOx catalysts
(Elsevier, 2000-03)
The effect of composition and of surface properties on alcohol-coupling reactions was studied on MgyAlOx catalysts using C2H5OH or 13CH3OH/1–12C3H7OH mixtures as reactants. Samples with Mg/Al ratios of 0.5–9.0 were obtained ...
Influence of the lanthanide(III) ion in {[Cu3Ln2(oda)6(H2O)6]•nH2O}n (LnIII: La, Gd, Yb) catalysts on the heterogeneous oxidation of olefins
(Royal Society of Chemistry, 2017)
© The Royal Society of Chemistry 2017.{[Cu3Ln2(oda)6(H2O)6]•nH2O}n (LnIII: La, Gd, Yb; odaH2: oxydiacetic acid) are reported as reusable heterogeneous catalysts in the oxidation of olefins. An influence of the LnIII ion ...
Empirical energy - Density relationships for the analysis of substituent effects in chemical reactivity
(2000)
Electronic substituent effects may be rationalized in terms of Hammett- like linear relationships between global energy-dependent quantities and local electronic descriptors of reactivity. These linear relationships are ...
Role of acystine-based Gemini surfactant ligand in the synthesis of catalytic active silver nanoparticles
(Elsevier Science, 2019-06)
We report the synthesis in water of colloidal silver nanoparticles (AgNP) using a Gemini lipoamino acid surfactant derived from cysteine as a capping agent. The Gemini surfactant interacts with the metal surface mainly in ...
