Mechanisms of Formation of Hemiacetals: Intrinsic Reactivity Analysis
(AMER CHEMICAL SOC, 2012)
The reaction mechanism of the hemiacetal formation from formaldehyde and methanol has been studied theoretically at the B3LYP/6-311+ +G(d,p) level. In addition to the study of the reaction between the isolated reactants, ...
ACID-BASE REACTIONS: CONCEPT, REPRESENTATION AND GENERALIZATION FROM THE ENERGY INVOLVED IN TRANSFORMATIONS
(SOC BRASILEIRA QUIMICASAO PAULO, 2012)
ACID-BASE REACTIONS: CONCEPT, REPRESENTATION AND GENERALIZATION FROM THE ENERGY INVOLVED IN TRANSFORMATIONS. Undergraduate students on the first year of Chemistry Courses are unfamiliar with the representation of acid-base ...
Lactic acid bacteria decarboxylation reactions in cheese
(Elsevier, 2016-11)
Fermentation in cheese comprises oxidation-reduction of carbohydrates to yield organic acids, alcohols and carbon dioxide. Furthermore, organic acid and amino acid metabolism produces a series of compounds that positively ...
Reações ácido-base: conceito, representação e generalização a partir das energias envolvidas nas transformações
(Sociedade Brasileira de Química, 2012-01-01)
Undergraduate students on the first year of Chemistry Courses are unfamiliar with the representation of acid-base reactions using the ionic equation H+ + OH- → H2O. A chemistry class was proposed about acid-base reactions ...

Computational characterization of the role of the base in the Suzuki-Miyaura cross-coupling reaction
(Amer Chemical SocWashingtonEUA, 2005)
In situ quantification of the active acid sites of H6P2W18O62·nH 2O heteropoly-acid through chemisorption and temperature programmed surface reaction of isopropanol
(Elsevier Science, 2004-06)
Isopropanol chemisorption and temperature programmed surface reaction analyses were used to determine the nature, amount and acid strength of the active sites of bulk WO3, monolayer supported tungsten oxide over titania ...
An information-theoretic resolution of the ambiguity in the local hardness
(Royal Society of Chemistry, 2014)
The ambiguity of the local hardness is resolved by using information theory to select definitions of the local hardness that are as close as possible to a well-defined approximate formula for the local hardness. A condensed ...
