Two-stage alkaline and acid pretreatment applied to sugarcane bagasse to enrich the cellulosic fraction and improve enzymatic digestibility
(2020-01-01)
Sugarcane bagasse (SB) is made up of cellulose (32-43%), hemicellulose (19-34%) and lignin (14-30%). Due to high recalcitrant nature of SB, pretreatment is required to deconstruct its structure and enrich the cellulosic ...
Multi plate freeze concentration: Recovery of solutes occluded in the ice and determination of thawing time
(Food Science and Technology International, 2013-06-19)
The retention of solutes in the ice formed in a falling-film freeze concentrator (multi-plate freeze-concentrator) was analysed. Solutions of fructose, glucose and sucrose and a simulated juice with initial concentrations ...
Fractional and integer stages of lithium ion-graphite systems: The role of electrostatic and elastic contributions
(Royal Society of Chemistry, 2020-07)
In the present work, we analyze the hot topic of integer and fractional stages of lithium-ion batteries by using Monte Carlo simulations. While fractional stages have been demonstrated through several experimental, simulation ...
Influência do número kappa, dos ácidos hexenurônicos e da lignina no desempenho da deslignificação com oxigênio
(2006-10-25)
This study aimed at determining the effect of kappa number, lignin and hexenuronic acid contents on oxygen stage performance. Industrial brown pulps produced by the ITC and KobudoMARI cooking technologies, of kappa number ...

Grand canonical Monte Carlo study of Li intercalation into graphite
(Electrochemical Society, 2018-06)
A computational model is proposed to study lithium-graphite intercalation compounds in the framework of Monte Carlo simulations in the Gran Canonical Ensemble. The results suggest the existence of fractional stages between ...
Mössbauer spectroscopic study of the early crystallization stage of iron(III) hydroxide particles
(1986-12-01)
Mössbauer spectroscopy was used to investigate the early aging stage of iron(III) hydroxide sols prepared by oxidation of Fe(CO)5 in ethanolic solution, followed by vacuum drying at room temperature. One sample was composed ...
Avaliação agronômica e nutricional do híbrido de sorgo BRS 610 em quatro estádios
(Universidade Federal de Minas GeraisUFMG, 2013-07-16)
The objective of this study was to evaluate the agronomic characteristics, nutritional composition and the in vitro ruminal fermentation kinetics of the whole plants and their fractions (panicle, stem and leaf) of BRS 610 ...
Organic fractions influence on biogas generation from potato residues. Kinetic model generalization
(Pergamon-Elsevier Science Ltd, 2013-12)
Bioenergy production as methane is being increasingly used to process low value by-products or not commercial wastes, in particular those which contain high levels of biodegradable organic matter such as potato residue. ...
