Hidrogeoquímica e hidrología isotópica
(Editora Geotech, 2004)
Las aguas naturales adquieren su composición química mediante un proceso complejo, donde intervienen factores geológicos, hidrogeológicos, geomorfológicos, climáticos, pedológicos, antrópicos, químico-físicos y otros ...
Influência do cancro basal em Eucalyptus grandis nas propriedades da madeira e polpação kraft
The objective of this research is to assess the influences of basal canker on wood properties for the kraft pulp production. The material consisted of seeded E. grandis trees classified into 4 levels of basal canker severity ...
Development of a robust algorithm to compute reactive azeotropes
(Brazilian Soc Chemical EngSao PauloBrasil, 2006)
Characterization of the pre-treated biomass of Eichhornia crassipes (water hyacinth) for the second generation ethanol production
Eichhornia crassipes (water hyacinth), is considered an aquatic pest. An alternative to solve the excess water hyacinth problem is to use the biomass for second generation ethanol. This process can be divided into: collection ...
ESTIMATING REACTION CONSTANTS BY AB INITIO MOLECULAR MODELING: A STUDY ON THE OXIDATION OF PHENOL TO CATECHOL AND HYDROQUINONE IN ADVANCED OXIDATION PROCESSES
(BRAZILIAN SOC CHEMICAL ENGSAO PAULO, 2012)
Molecular modeling is growing as a research tool in Chemical Engineering studies, as can be seen by a simple research on the latest publications in the field. Molecular investigations retrieve information on properties ...
Combined chemical oxidation and biological processes for herbicide degradation
BACKGROUND: Fenton and photo-Fenton processes were explored as photochemical pre-treatments to improve the biodegradability of wastewater containing atrazine, a commercial pesticide. The effects of H2O2, Fe3+ and irradiation ...
Paired Electrochemical Processes: Overview, Systematization, Selection Criteria, Design Strategies, and Projection
(Sociedad Química de México, 2016)
Chemical genomics approaches in plant biology.
Chemical genomics (i.e., genomics-scale chemical genetics) approaches are based on the ability of low-molecular-mass molecules to modify biological processes. Such molecules are used to affect the activity of a protein or ...
