Assessment of mechanical, thermal properties and crystal shapes of monoclinic tricalcium silicate from atomistic simulations
(2021-02-01)
The two most common polymorphs in industrial alite, M1 and M3, were characterized at the molecular scale. Different methods were employed and discussed to assess mechanical properties and specific heat of both polymorphs. ...
Revealing Monoamine Oxidase B Catalytic Mechanisms by Means of the Quantum Chemical Cluster Approach
(Amer Chemical Soc, 2015)
Two of the possible catalytic mechanisms for neurotransmitter oxidative
deamination by monoamine oxidase B (MAO B), namely, polar nucleophilic and hydride
transfer, were addressed in order to comprehend the nature of ...
Prediction of catalytic activity of Pt3Re1 alloy for C-C bond cleavage in the ethanol oxidation reaction
(2016-05-30)
Design of catalysts able to cleave C-C bond in ethanol oxidation reaction at low temperatures is primordial for improving the direct ethanol proton exchange membrane fuel cells. Pt-Re alloy seems to be an appropriate ...
Energy depletion of embryos and yolk-sac feeding larvae of the liparid snailfish Careproctus pallidus (Vaillant 1888)
(Springer, 2019-04)
The snailfish, Careproctus pallidus, is a liparid fish that spawns within the branchial chambers of the king crab Lithodes santolla and develops its embryonic stages inside the chambers until it forms a well-developed ...
Major components of energy drinks (caffeine, taurine, and guarana) exert cytotoxic effects on human neuronal SH-SY5Y cells by decreasing reactive oxygen species production
(2013-06-12)
Scope. To elucidate the morphological and biochemical in vitro effects exerted by caffeine, taurine, and guarana, alone or in combination, since they are major components in energy drinks (EDs). Methods and Results. On ...

Environmental catalysis and the chemistry of SO2 on oxide surfaces: fundamental principles for the cleavage of S-O bonds
(Facultad Experimental de Ciencias de la Universidad del Zulia, 2011)
Estudo teórico da reatividade de ésteres de fosfato em fase gasosa e em solução aquosa
(Universidade Federal de Minas GeraisUFMG, 2014-07-30)
This study investigated the cleavage of P-OC2H5 bond in phosphate esters, dianionic monoethyl phosphate [H5C2OPO32-], monoanionic diethyl phosphate [(H5C2O)2PO2-] and neutral triethyl phosphate [(H5C2O)3PO], with attack ...
Chemiluminescence-based uphill energy conversion
(ROYAL SOC CHEMISTRY, 2011)
The conversion of red excitation light into blue emission light (uphill energy conversion) using unstable 1,2-dioxetanes is described. The method is based on 1,2-dioxetane formation by red-light sensitized photooxygenation ...
Purification, characterization, and specificity determination of a new serine protease secreted by penicillium waksmanii
(2013-01-01)
The purpose of this work was to purify a protease from Penicillium waksmanii and to determine its biochemical characteristics and specificity. The extracellular protease isolated that was produced by P. waksmanii is a ...
