A simple cation exchange model to assess the competitive adsorption between the herbicide paraquat and the biocide benzalkonium chloride on montmorillonite
(Elsevier Science, 2021-02-20)
Since adsorption on clay minerals is one of the most popular water-pollutant removal method, it is important to consider the coexistence of several compounds that can affect pollutant retention. In this work, the competitive ...
Modeling of cation diffusion in oxygen ion conductors using molecular dynamics
(Elsevier Science, 2004-11)
Cation diffusion in ionic conducting oxides is modelled using molecular dynamics (MD). As example systems LSGM (Sr- and Mg-doped LaGaO3; perovskite structure) and YSZ (Y-doped ZrO2; fluorite structure) were investigated. ...
5,5′-Bis-vanillin derivatives as discriminating sensors for trivalent cations
(Elsevier, 2015-05)
Several bis-vanillin derivatives containing semicarbazone moieties have been prepared and usedin discriminating trivalent cations. The prepared probes are readily obtained and they are usuallyhighly crystalline. Depending ...
Visible Light Induced Cationic Polymerization of Epoxides by Using Multiwalled Carbon Nanotubes
(Wiley VCH Verlag, 2018-07)
The visible light induced cationic polymerization of epoxides can be achieved by means of multiwalled carbon nanotubes (MWCNTs), which act as visible light photoinitiators via a radical-induced cationic photopolymerization ...
Identification of carbonium and carbenium ions by QTAIM
(Sociedade Brasileira de Química, 2009)
A ferramenta de Gassman-Fentiman da demanda crescente de elétrons foi usada para identificar íons carbênios e íons carbônios. Contudo, devido ao seu entendimento ambíguo, ela foi pivô de uma disputa histórica. Nós aplicamos ...
