Polyhydroxybutyrate (PHB) produced from red grape pomace: Effect of purification processes on structural, thermal and antioxidant properties.
(Elsevier, 2022-09)
Red grape pomace was used as a source for poly(3-hydroxybutyrate) (PHB) production, which was then subject to a range of purification processes. The different PHB biopolymers were characterized for chemical structure, ...
Click chemistry: an efficient toolbox for the design of chitosand-based hydrogels for biomedicine
(2020-05-28)
The present thesis was focused on the development of new gel-type biomaterials form chitosan withexcellent stimuli-responsive properties using different click reactions. To this end, in the first place,chitosan was endowed ...
Tailoring physicochemical properties of collagen-based composites with ionic liquids and wool for advanced applications
(Elsevier, 2022-06)
Wool, choline dihydrogen phosphate ([Ch][DHP]) or choline serinate ([Ch][Seri) ionic liquids (ILs) were incorporated into native collagen formulations and films were prepared by compression molding. Scanning electron ...
Characterization of the Compounds Released in the Gaseous Waste Stream during the Slow Pyrolysis of Hemp (Cannabis sativa L.)
(MDPI, 2022-04-27)
This study aims to characterize and valorize hemp residual biomass by a slow pyrolysis process. The volatile by-products of hemp carbonization were characterized by several methods (TGA, UV-VIS, TLC, Flash Prep-LC, UHPLC, ...
Fractionation of lignin using organic solvents: A combined experimental and theoretical study
(Elsevier, 2021-01-31)
Refining of industrial lignin to produce homogeneous fractions is essential for high-value applications. However, the understanding of key interactions between a variety of solvents with lignin polymer is still uncertain. ...
Turbidity Changes during Carbamazepine Oxidation by Photo-Fenton
(MDPI, 2021-07-24)
The objective of this study is to evaluate the turbidity generated during the Fenton photo-reaction applied to the oxidation of waters containing carbamazepine as a function of factors such as pH, H<sub>2</sub>O<sub>2</sub> ...
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 ...
Colour Changes during the Carbamazepine Oxidation by Photo-Fenton
(MDPI, 2021-03-18)
The oxidation of aqueous solutions of carbamazepine is conducted using the Fenton reagent, combined with the photolytic action of a 150 W medium pressure UV lamp, operating at T = 40 °C. The effect of acidity is analysed ...
3D-Printed Hybrid Collagen/GelMA Hydrogels for Tissue Engineering Applications
(MDPI, 2022-10-25)
Bioprinting is an emerging technology involved in the fabrication of three-dimensional tissue constructs for the repair and regeneration of various tissues and organs. Collagen, a natural protein found abundantly in the ...
Development of a Novel Biobased Polyurethane Resin System for Structural Composites
(MDPI, 2022-10-27)
Polyurethanes are gaining increasing interest for their use as structural components subjected to cyclic loads, such as leaf springs. Thermoset polyurethane (PUR) based technology offers some advantages, such as fatigue ...
