Study of hemicelluloses composition of different tree species, extraction using subcritical water with a batch cascade reactor

Hemicelluloses from 10 different tree species commonly growing in the Castilla y Leon region have been extracted with a batch cascade reactor. Raw materials came from tree branches, cut during the seasonal pruning. The aim was to correlate the yield of hemicellulose achieved through the extractions, with the total composition and the structure of the […]

Wine lees valorization: antioxidant activities

Wine lees are the dregs formed during the different fermentation steps in the vinification process.  These wine less constitute a novel source rich in polyphenols and other compound of high added value. Freeze-dried aging wine lees were, for the first time, exhaustively characterized in terms of antioxidant capacity with different assays: ORAC, HORAC, HOSC and […]

Silica aerogels; alternative matrix for catalytic palladium nanoparticles

Effective routes to obtain more valuable products from biomass requires the design of efficient catalysts. Novel catalytic structures are therefore needed to overcome the present challenges. These novel structures require the integration of support active sites in a way that preserves their advantages and capabilities. Here, we introduce novel catalytic structures achieved by the integration […]

Efficient production of soy-bean lecithin – pluronic L64® encapsulated quercetin particles in nanometric scale using SFEE and PGSS drying processes

Quercetin occurs in various fruits, vegetables and many other food components. According to preliminary studies, it has strong antioxidant-, antiviral-, antibacterial-, antihistaminic-, and anti-inflammatory effect. Due to these properties, quercetin is a highly promising material against a wide variety of diseases, including cancer. A major limitation for the clinical application of quercetin is its low […]

Reversible hydrogen sorption in the composite made of magnesium borohydride and silica aerogel

The application of hydrogen as an energy vector requires the development of new hydrogen storage systems. Magnesium borohydride Mg(BH4)2 is a promising hydrogen storage material because of its high hydrogen storage capacity (14,8wt% H2, 0.112 Kg/L). However, it is still limited by slow hydrogen release kinetics and by the harsh conditions required for reversible hydrogen […]
