Developing active and intelligent films through the incorporation of grape skin and seed tannin extracts into gelatin
(Elsevier, 2022-09)
To achieve sustainability in the wine industry, by-products from winery operations are being diverted from waste streams and turned into beneficial use. Grape seed tannin (SeedT) and skin tannin (SkinT) extracts were used ...
Supernucleation Dominates Lignin/Poly(ethylene oxide) Crystallization Kinetics
(American Chemical Society, 2022)
The effect of lignin nanoparticles (LNPs) on the crystallization kinetics of poly(ethylene oxide) (PEO) is examined. Lignin from spruce and ionic isolation was used to prepare LNPs with a number-averaged diameter of 85 nm ...
Influence of lignin modifications on physically crosslinked lignin hydrogels for drug delivery applications
(Elsevier, 2022-09)
So far, the possibility of synthesizing hydrogels based on multiple biopolymers has been investigated, and among them lignin has proven to be one of the potentials for this purpose due to the multiple advantages it offers. ...
Fine-tune of lignin properties by its fractionation with a sequential organic solvent extraction
(Elsevier, 2022-01)
[EN] In this work, different lignins were obtained from two different extraction methods (kraft and organosolv) but from the same raw material (Eucalyptus globulus sp.). They were subsequently fractionated to determine the ...
Impact of the lignin type and source on the characteristics of physical lignin hydrogels
(Elsevier, 2022-04)
[EN] Multiple natural polymers have been investigated for the synthesis of hydrogels to the present date, but lignin has demonstrated to be a promising one for this purpose for the multiple advantages it offers. Lignin can ...
Physicochemical Characterization of Phase Change Materials for Industrial Waste Heat Recovery Applications
(MDPI, 2022-05-16)
The recovery and storage of process heat in industrial applications are some of the key factors to improve the sustainability and reliability of high temperature applications. In this sense, one of the main drawbacks is ...
Desarrollo de sistemas catalíticos heterogéneos para la obtención de hidrógeno y propileno
(2022-10-20)
La presente Tesis Doctoral aborda la necesidad de abogar por un sistema energético e industrial más sostenible y, por tanto, la mejora y optimización de procesos ya existentes. El hidrógeno se considera un vector de energía ...
Réactivité d'argile modifiée par polymérisation. Etude de l'adsorption des polluants des eaux usées
(2022-03-19)
La contamination de l'eau par de nombreuses formes de polluants tels que les composés organiques volatils (COV), les colorants synthétiques et les métaux lourds peuvent endommager notre planète et posent un problème pour ...
Effect of gelatin concentration, ribose and glycerol additions on the electrospinning process and physicochemical properties of gelatin nanofibers
(Elsevier, 2022-11)
Rheological properties of gelatin-based solutions containing different concentrations of ribose and/or glycerol were assessed before electrospun mats were manufactured and their properties investigated. Characterization ...
Electroconductive Photo-Curable PEGDA-Gelatin/PEDOT:PSS Hydrogels for Prospective Cardiac Tissue Engineering Application
(Frontiers Media, 2022-06)
Electroconductive hydrogels (ECHs) have attracted interest for tissue engineering applications due to their ability to promote the regeneration of electroactive tissues. Hence, ECHs with tunable electrical and mechanical ...
