Fumarate Copolymer–Chitosan Cross-Linked Scaffold Directed to Osteochondrogenic Tissue Engineering
(Wiley VCH Verlag, 2017-05)
Natural and synthetic cross-linked polymers allow the improvement of cytocompatibility and mechanical properties of the individual polymers. In osteochondral lesions of big size it will be required the use of scaffolds to ...
Surface energies of linear and cross-linked polymers based on isobornyl methacrylate and methacryl-heptaisobutyl POSS
(Pergamon-Elsevier Science Ltd, 2009-02)
The use of monofunctional polyhedral oligomeric silsesquioxanes (POSS) as polymer modifiers requires controlling the phase separation process producing POSS-rich and polymer-rich domains that occurs in most systems due to ...
Improved development in magnetic Xyl-CLEAs technology for biotransformation of agro-industrial by-products through the use of a novel macromolecular cross-linker
(Elsevier Science, 2020-09)
Cross-Linked Enzyme Aggregates (CLEAs) technologies for enzyme immobilization are influenced by mass transference problems as the degree of molecular crosslinking achieved strongly affects the enzyme exposure to the ...
Hydrophilic and hydrophobic interactions in cross-linked chitosan membranes
(Elsevier Science Sa, 2013-02)
Chitosan membranes with different cross-linking density were prepared by modifying cross-linking time. Sodium tripolyphosphate was the cross-linking agent. A pulsed nuclear magnetic resonance study was performed on ...
Lithium Metal Protection by a Cross-Linked Polymer Ionic Liquid and Its Application in Lithium Battery
(American Chemical Society, 2020-01)
Lithium (Li) metal has been considered as an important anode candidate to reach more powerful energy storage devices with higher gravimetric and volumetric capacities. Nevertheless, the growth of high surface area lithium ...
Physico-chemical properties and in vitro digestibility of edible films made from plantain flour with added Aloe vera gel
(Elsevier, 2016-10)
The aim of this study was to relate the physicochemical properties of edible films derived from plantain flour-glycerol containing different concentrations of Aloe vera (Av) gel to both their in vitro digestibility and ...
Enhancing Water Resistance, Tensile Properties and UV-Shielding Capacity of Bovine Gelatin Films Modified with Epoxidized Soybean Oil and Glyoxal during Processing
(Somato Publications, 2020-01)
The present work is focused on the use of epoxidized soybean oil (ESO, 10 wt%) as hydrophobizing additive, glycerol as plasticizer (Gly, 30 wt.%),and glyoxal (GLX, 2 wt%) as low-toxicity cross-linking agent to endow bovine ...
TEOS as an improved alternative for chitosan beads cross-linking: A comparative adsorption study
(John Wiley & Sons Inc, 2014-11)
In this work the use of tetraethoxysilane (TEOS) for cross-linking of chitosan hydrogel beads was studied at the level of 1 mmol TEOS per gram of chitosan. They were compared with glutaraldehyde and epichlorohydrin ...
Preparation and characterization of modified starches obtained in acetic anhydride/tartaric acid medium
(Wiley VCH Verlag, 2020-03)
In the current contribution chemically modified starches are prepared by reaction of corn starch in hot acetic anhydride, containing tartaric acid. Characterization of the starch products shows evidence that the incorporation ...
Vanillin as a natural cross-linking agent in chitosan-based films: Optimizing formulation by response surface methodology
(Elsevier, 2019-06)
One way of improving mechanical and water barrier properties of chitosan films is through cross-linking reactions. Cross-linking agents usually used for this purpose include glutaraldehyde, glyoxal, and formaldehyde, which ...
