Quantification of the crystalline versus amorphous fraction is an important objective for the structural characterization of glass-ceramics. Owing to its well-documented ability of differentiating between crystalline and ...

Samples of Eucalyptus urograndis and Eucalyptus grandis sawdust were autohydrolyzed in aqueous conditions to reach temperatures in the range 110-190 °C and reaction times of 0-150 min in a minireactor. In each minireactor ...

The acid hydrolysis of cellulose with crystalline and amorphous fractions is analyzed on the basis of autocatalytic model with a positive feedback of acid production from the degraded biopolymer. In the condition of low ...

Time-resolved photolysis studies of riboflavin (RF) were carried out in the presence and absence of α-, βH- and βL-crystallins of bovine eye lens. The transient absorption spectra, recorded 5 μs after the laser pulse, ...

The effects of sunflower oil (SFO) and the sucrose esters (SE) P-1670, P-170, and S-170 on crystalline microstructure of a high-melting milk fat fraction (HMF) was studied by polarized-light microscopy (PLM) and confocal ...

The formation of the crystalline phase of polypropylene in the presence of four different types of CaCO3 was studied. All composites were prepared by melt mixing and extrusion and the concentration of CaCO3 was maintained ...

Sugarcane culm has different types of tissue organization, and its heterogeneity can influence the bagasse quality generated in the sugar/ethanol industry. The heterogeneity of the sugarcane bagasse contributes to the ...

Due to the growing demand for renewable energy, the energy based on biomass plays an important role in energy policies of countries all over the world. Seven different pretreatments were performed on SCB to obtain yields, ...

Amaranth nutritional value has been widely recognized, but the required conditions for its processing cannot be adapted to traditional technologies. For the proposal of alternative strategies, the changes of several ...

A small fraction of an acrylate liquid crystalline monomer (<= 5%) is mixed into nematic and smectic liquid crystalline phases, and polymerised through the application of a voltage (electropolymerisation). Polarising ...
