A Theoretical Study of the Effect of Zr-, Nb-Doped and Vacancy-like Defects on H Desorption on MgH2 (110) Surface
(American Chemical Society, 2014-02)
DFT calculations were used to study hydrogen desorption energy in a set of pure, Nb- or Zr-doped systems, containing vacancy-like defects and a MgH2 (110) defect-free surface. The preferential location site for dopants was ...
Lemon essential oil desorption from polypropylene/talc nanocomposite films
A phenomenological analysis on desorption mechanism of lemon essential oil in semicrystalline polymer nanocomposites is performed. Films made with polypropylene and talc nanoparticles obtained by blown extrusion are used ...
Sorption of mercury (II) in Amazon soils from column studies
(Pergamon-elsevier Science LtdOxfordInglaterra, 2005)
A study of the process of desorption of hexavalent chromium
(Brazilian Society of Chemical Engineering, 2003)
Biosorption and desorption of lanthanum(III) and neodymium(III) in fixed-bed columns with Sargassum sp.: Perspectives for separation of rare earth metals
Rare earth (RE) metals are essentials for the manufacturing of high-technology products. The separation of RE is complex and expensive; biosorption is an alternative to conventional processes. This work focuses on the ...
Rapid determination of desorption efficiency, and analysis of solvent mixtures for occupational exposure studies
An analytical procedure has been developed for simultaneous determination of solvent mixture vapors to enable evaluation of occupational exposure. To determine the desorption efficiency the volatile components of the solvent ...
Sorption and desorption of glyphosate in Mollisols and Ultisols soils of Argentina
(Society of Environmental Toxicology and Chemistry, 2017-05)
In Argentina, glyphosate use has increased exponentially in the past years due to the widespread adoption of no-till management combined with genetically modified glyphosate-resistant crops. This massive use of glyphosate ...
