[:en]Our economy relies on fossil fuels that can be converted into energy and chemicals, but this model is endangered by depletion of resources and environmental problems. To solve this dilemma, we can find inspiration in photosynthetic organisms that consider CO2 as a carbon source and not as waste. CO2 utilization processes have experienced a considerable […]

NEW REVIEW: Understanding biomass fractionation in subcritical&supercritical water
[:en]Biomass fractionation into its individual building blocks poses a major challenge to the biorefinery concept. The recalcitrance of the lignocellulose matrix and the high crystallinity of cellulose make typical feed stocks difficult to separate into their components. Hydrothermal processing fractionates biomass by its hydrolysis. However, a deep knowledge of hydrolysis principles is required since an […]

Scaling-Up Of SFEE, Identification Of Process Parameters On Product Characteristics And Economic Impact
A scaled-up SFEE equipment (Fig 1) was designed and used for producing sufficient amount of aqueous suspensions for PGSS-drying treatment. Using PGSS-drying water content of aqueous suspensions was extracted, and hence long-term stability of product was increased, without irreversible change on its morphology. The scaled-up SFEE equipment consists of an electrically tempered extractor vessel with […]

[Thesis]: Green processes applied to nanoparticle technology: synthesis and formulation by Víctor Martín Velasco
Dr. Víctor Martín Velasco defended his thesis on Tuesday 4th October 2016 at the University of Valladolid. Nowadays, nanoparticle technology is investigated for being applied in a lot of fields, for example, in catalysis, materials, electronics and biomedicine, one of the most promising. This versatility is because of their properties associated to their size and morphology, such as surface […]
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 […]
