Influence of previous acid etching on bond strength of universal adhesives to enamel and dentin
(2017-03-01)
The objective of this study was to evaluate the effect of acid pretreatment on the bond strength of composite resin bonded to enamel and dentin with 2 different universal self-etching adhesives. The null hypothesis was ...
Taguchi's Methodology for Determining Optimum Operating Conditions in Hydrothermal Pretreatments Applied to Canola Seeds
(Wiley, 2014-03)
The aim of the present work was to determine the operational optimum conditions in hydrothermal pretreatments applied to canola seeds. The effect of these pretreatments on the canola oil extraction yield and quality was ...
Biodegradation pretreatment of wood of E. grandis, E. dunnii, and E. benthamii to work in biorefinery processes
(Tech Science Press, 2016)
Nowadays, there is a great interest in using lignocellulosic materials as substrate for the production of biorefi nery products. Eucalypti are good options to use as crops to obtain different kinds of biofuels and derivatives, ...

Sieving process selects sugarcane bagasse with lower recalcitrance to xylan solubilization
(2020-01-01)
BACKGROUND: Sugarcane bagasse is a heterogeneous and organized material that needs a pretreatment to access the polysaccharides (cellulose and xylan). The particle size of a non-milled bagasse can influence the xylan and ...
Optimization of phosphoric acid pretreatment conditions to produce lactic acid from eucalyptus residues.
(2023)
Forestry lignocellulose biomass can be used as a potential substrate in an integrated biorefinery, given the wide products variability that can arise from the chemical structure of its components (cellulose, hemicellulose, ...
Conversion of sunflower seed hulls, waste from edible oil production, into valuable products
(Elsevier, 2019-02-06)
Sunflower seed hulls are an abundant waste produced by the edible oil industry. Pyrolysis was assessed as a way of turning this material into a liquid rich in valuable products, as well as leading to densification of this ...
Optimization of FeSO4-assisted sulfuric acid hydrolysis for improved sugar yield from sugarcane bagasse
(2020-10-01)
Sugarcane bagasse (SB) consists of two major sugar polymers (cellulose and hemicelluloses) connected to lignin. Due to the recalcitrant nature of SB, pretreatment is considered a crucial process step before it can be ...
THE EFFECT of DENTIN PRETREATMENT on THE MICROTENSILE BOND STRENGTH of SELF-ADHESIVE RESIN CEMENTS
(Mosby-elsevier, 2010-10-01)
Statement of problem. Self-adhesive cements have lower bond strength than conventional resin cements that rely on the application of etch-and-rinse adhesive systems.Purpose. The purpose of this study was to evaluate the ...
