Analysis of the effect of temperature reaction time on yields, compositions and oil quality in 3 catalytic and non-catalytic lignin solvolysis in a formic acid/water media using experimental design.
(Elsevier, 2017-03-01)[EN] The catalytic solvolysis of Norway spruce (Picea abies L.) lignin in a formic acid/water media was explored at different temperatures and reaction times (283–397 °C and 21–700 min, respectively). Non-catalyzed experiments ... -
Antioxidant, Antifungal and Phytochemical Investigations of Capparis spinosa L.
(MDPI, 2021-10-19)The antioxidant and antifungal activities of crude hydro-ethanolic extract from Capparis spinosa L. (Capparidaceae) leaves and their fractions, obtained by liquid-liquid extraction (LLE) using solvents with increasing ... -
Application of a Combined Adsorption−Ozonation Process for Phenolic Wastewater Treatment in a Continuous Fixed-Bed Reactor
(MDPI, 2021-08-22)This work studied the removal of phenol from industrial effluents through catalytic ozonation in the presence of granular activated carbon in a continuous fixed-bed reactor. Phenol was chosen as model pollutant because of ... -
Application of zeolites for the production of biofuels and furans from hexose sugars in ethanol
(Elsevier, 2024-02)The use of zeolites as catalysts in the transformation of glucose and 5-hydroxymethylfurfural (HMF) into 5-ethoxymethylfurfural (EMF) was evaluated. The behaviour of the catalysts could be explained by their morphology, ... -
Appraisal of agroforestry biomass wastes for hydrogen production by an integrated process of fast pyrolysis and in line steam reforming
(Elsevier, 2023-12)The pyrolysis and in line steam reforming of different types of representative agroforestry biomass wastes (pine wood, citrus wastes and rice husk) was performed in a two-reactor system made up of a conical spouted bed and ... -
Assessment of Biomass Energy Potential and Forest Carbon Stocks in Biscay (Spain)
(MDPI, 2016-03)The aim of this research is to identify, quantify and characterize the potential available forest biomass of Pinus radiata D. Don and Eucalyptus globulus Labill. across Biscay province in northern Spain. In order to do ... -
Assessment of Bleached and Unbleached Nanofibers from Pistachio Shells for Nanopaper Making
(MDPI, 2021-03-04)Cellulose and lignocellulose nanofibrils were extracted from pistachio shells utilizing environmentally friendly pulping and totally chlorine-free bleaching. The extracted nanofibers were used to elaborate nanopaper, a ... -

Automatic feedback and assessment of team-coding assignments in a DevOps context
(Springer, 2023)We describe an automated assessment process for team-coding assignments based on DevOps best practices. This system and methodology includes the definition of Team Performance Metrics measuring properties of the software ... -
Azopolymer film as an actuator for organizing multiwall carbon nanotubes
(Elsevier, 2017-01-25)In this work we show the feasibility of using an azopolymer as an actuator to induce nano- and microscale movements controlled with light from the far field. We study azopolymers and their interaction with multi-walled ... -
Bacterial nanocellulose production from naphthalene
(Wiley, 2019-07)Polycyclic aromatic compounds (PAHs) are toxic compounds that are released in the environment as a consequence of industrial activities. The restoration of PAH-polluted sites considers the use of bacteria capable of degrading ... -
Bacterial-Cellulose-Derived Carbonaceous Electrode Materials for Water Desalination Via Capacitive Method: the Crucial Role of Defect Sites
(Elsevier, 2020-10-15)Electrosorptive desalination is a very simple and appealing approach to satisfy the increasing demand for drinking water. The large-scale application of this technology calls for the development of easy-to-produce, cheap ... -
Base catalysed depolymerization of lignin: Influence of organosolv lignin nature
(2014-07)Three different lignins obtained from olive tree pruning by organosolv processes (acetosolv, formosolv and acetosolv/formosolv) were depolymerized by alkaline hydrolysis in a batch reactor to produce high value added ... -
Bio-Based Polyurethane Networks Derived from Liquefied Sawdust
(MDPI, 2021-06-07)The utilization of forestry waste resources in the production of polyurethane resins is a promising green alternative to the use of unsustainable resources. Liquefaction of wood-based biomass gives polyols with properties ... -
Bioactive molecules in wood extractives: Methods of extraction and separation, a review
(Elsevier, 2022-10)Bioactive molecules are those capable of interacting with living organisms, causing changes in them. Wood extractives contain important amounts of these molecules, and some of them have good antioxidant and antimicrobial ... -
