Interactions between 1-butyl-3-methylimidazolium tetrafluoroborate ionic liquid and gamma-Al2O3 (100) surface calculated by density functional theory
(WILEY-BLACKWELLHOBOKEN, 2013-08-02)
The main aim of this work is to investigate the 1-butyl-3-methylimidazolium tetrafluoroborate ([C4C1Im]+[BF4]-) ionic liquid (IL) adsorption on the gamma-Al2O3 (100) by density functional theory calculations to try to ...
In vitro Evaluation of Surface Free Energy of Dentin after Treatment with Sodium Trimetaphosphate Associated or Not with Fluoride, Exposed or Not to Calcium
(2022-03-01)
It has been stated that sodium trimetaphosphate (TMP) promotes a more anionic dentin surface inducing greater calcium (Ca) and phosphate precipitation. The aim of the present study was to evaluate in vitro the surface free ...
Crystal structure of a dimeric Ser49 PLA(2)-like myotoxic component of the Vipera ammodytes meridionalis venomics reveals determinants of myotoxicity and membrane damaging activity
(Royal Soc Chemistry, 2012-01-01)
Myotoxicity and membrane damage play a central role in the life-threatening effects of the viper envenomation. Myotoxins are an important part of the viper venomics. A Ser49 PLA(2)-like myotoxin from the venom of Vipera ...
Competing Lipid-Protein and Protein-Protein Interactions Determine Clustering and Gating Patterns in the Potassium Channel from Streptomyces lividans (KcsA)
(Amer Soc Biochemistry Molecular Biology, 2015)
There is increasing evidence to support the notion that membrane
proteins, instead of being isolated components floating in
a fluid lipid environment, can be assembled into supramolecular
complexes that take part in a ...

Adsorption of 2-propanol on MgO Surface: A Combined Experimental and Theoretical Study
(Elsevier Science, 2014-12-04)
The adsorption of 2-propanol (or isopropanol) on MgO was studied using infrared (IR) spectroscopy and density functional theory (DFT) simulations. The analysis of IR spectra indicates that the molecule can adsorb either ...
Adsorption of picloram herbicide on montmorillonite: Kinetic and equilibrium studies
(Elsevier Science, 2014-05)
The kinetics of the adsorption of picloram (PCM) onto montmorillonite (Mt) was studied in situ by attenuated total reflectance Fourier-transform infrared spectra (ATR-FTIR). Pseudo-first-order, pseudo-second-order, ...
Estudo do uso do magstream na flotabilidade de alguns sistemas minerais
(Universidade Federal de Minas GeraisUFMG, 1999-12-16)
present work consists of a series of studies involving the effect of the use of Magstream on mineral surface properties, specifically quartz and pyrite. The Magnetic fluidused by the equipment, a mixture of lignin sulphonate ...
Disponibilidade de nutrientes no solo: decomposição e liberação de compostos orgânicos de resíduos vegetais
(Sociedade Brasileira de Ciência do Solo, 2008-06-01)
O objetivo principal desta revisão foi reunir informações a respeito da ação de compostos orgânicos produzidos por plantas na disponibilidade de nutrientes nos solos, principalmente sobre os cátions Ca, Mg e K e sobre o ...
