(2008-09-01)La eliminación de metales presentes en aguas mediante bioadsorción es una alternativa al tratamiento convencional (precipitación decantación) de prometedoras expectativas. En este trabajo a escala de laboratorio se tratan ... -
Biocatalytic preparation of dichloropropyl acrylates. Application to the synthesis of poly(dichloropropyl acrylates)
(Elsevier, 2013)The synthesis of dichloropropyl acrylates from dichloropropyl dodecanoates through a transesterification process using diverse commercial lipases and whole cells (fungal resting cells) is presented. The synthesis was carried ... -
Biocatalytic Transformation of 5-Hydroxymethylfurfural into 2,5-di(hydroxymethyl)furan by a Newly Isolated Fusarium striatum Strain
(MDPI, 2021-02-06)The compound 2,5-di(hydroxymethyl)furan (DHMF) is a high-value chemical block that can be synthesized from 5-hydroxymethylfurfural (HMF), a platform chemical that results from the dehydration of biomass-derived carbohydrates. ... -
Biomarkers, matrices and analytical methods targeting human exposure to chemicals selected for a European human biomonitoring initiative
(Elsevier, 2020-11-20)The major purpose of human biomonitoring is the mapping and assessment of human exposure to chemicals. The European initiative HBM4EU has prioritized seven substance groups and two metals relevant for human exposure: ... -
Biosorption of cadmium by the protonated macroalga Sargassum muticum: Binding analysis with a nonideal, competitive, and thermodynamically consistent adsorption (NICCA) model
(Elsevier, 2005)Protonated biomass of the seaweed Sargassum muticum was investigated for its ability to remove cadmium(II) from aqueous solutions. In this work, a nonideal, semiempirical, thermodynamically consistent (NICCA) isotherm was ... -
Blueberry production in Chile: Current Status and Future Developments
(Sociedade Brasileira de Fruticultura, 2014)Chile has become a major actor in the blueberry industry as the most important supplier of off-season fresh fruit for the northern hemisphere. Blueberry exports passed from US$ 30 million (around 4,000 tons) in 2000 to US$ ... -
[BMIM][PF6] Promotes the synthesis of halohydrin esters from diols using potassium halides
(Japan Society for Analytical Chemistry, 2008)Haloesterification of diverse diols with various carboxylic acids was achieved using potassium halides (KX) as the only halide source in ionic liquids. The best yield was obtained in [BMIM][PF6] when 1,2-octanediol, palmitic ... -
Brownian Dynamics Computational Model of Protein Diffusion in Crowded Media with Dextran Macromolecules as Obstacles
(MDPI, 2017-03-09)The high concentration of macromolecules (i.e., macromolecular crowding) in cellular environments leads to large quantitative effects on the dynamic and equilibrium biological properties. These effects have been experimentally ... -
Building bridges: an integrated strategy for sustainable food production throughout the value chain
(Springer, 2013)The food production and processing value chain is under pressure from all sides-increasing demand driven by a growing and more affluent population; dwindling resources caused by urbanization, land erosion, pollution and ... -
Cadmium exposure during pregnancy and lactation: materno-fetal and newborn repercussions of Cd(II), and Cd–metallothionein complexes
(Royal Society of Chemistry, 2018)Cadmium (Cd) is a non-physiological heavy metal that can be harmful at low concentrations. Increasing anthropogenic activities are incrementing the risk of accumulation of this heavy metal in different organs and tissues ... -
