Article Previous Article Next Article Table of Contents Ab Initio Molecular Dynamics Study of Small Alkali Metal Clusters
(American Chemical Society, 2014)
In this work, the dynamics of the clusters of the type M3 with M a metal
alkaline atom from Li to Cs have been studied. Other heteroatomic mixed clusters like
LiNaK and one bigger cluster, Na7, have also been studied. ...
Alkali-silica reactivity of basaltic aggregates of Mesopotamia Argentina: Case studies
(Springer Heidelberg, 2019-10)
This work consists of two stages; first, studies were conducted to evaluate the potential reactivity of crushed material (6–20 mm fraction) from two quarries (named A and B) producing basaltic aggregates in the northeast ...
Evaluation of a simple alkaline pretreatment for screening of sugarcane hybrids according to their in vitro digestibility
(Elsevier B.V., 2013-11-01)
Lignin depletion in new cultivars or transgenic plants has been identified as a way to diminish the recalcitrance of lignocellulosic materials. Direct enzymatic digestion of these materials provides some discrimination ...
Profiles of alkali concentration and galactoglucomannan degradation in kraft impregnation of Scots pine wood: Experimental observations and modeling
(De Gruyter, 2015-02)
A deep understanding of alkali impregnation including the profiles of alkali concentration and hemicellulose degradation is necessary to analyze the optimization of current and innovative processes. In this paper, the ...
Mitigação da reação álcali-agregado em concreto com o emprego de resíduo de cerâmica vermelha e metacaulim
(Universidade do Vale do Rio dos Sinos, 2017-05-22)
The use of mineral additions through pozzolans, both naturally and artificially, has been adopted by several civil engineering professionals through the partial substitution of cement primarily in the production of concrete ...
