Gelatin and galactomannan-based scaffolds: Characterization and potential for tissue engineering applications.
The results indicated that the gelatin/galactomannan films are potential biomaterials for use as scaffolds for tissue engineering and were responsible to improve elasticity in the gelatin-based films. Expand
Experimental and theoretical study of hyperconjugative interaction effects on NMR 1J(CH) scalar couplings.
Hyperconjugative and electrostatic interactions effects on 1J(CH) spin-spin coupling constants (SSCCs) are critically studied from both theoretical and experimental points of view. A qualitativeExpand
The formation of imidazolium salt intimate (contact) ion pairs in solution.
1-n-Butyl-2,3-dimethylimidazolium (BMMI) ionic liquids (ILs) associated with different anions undergo H/D exchange preferentially at 2-Me group of the imidazolium in deuterated solvents. This processExpand
Confined water in imidazolium based ionic liquids: a supramolecular guest@host complex case.
The structure and function of water have been determined in condensed, solution and gas phases by X-ray diffraction studies, NMR, molecular dynamics simulations (MDS) and DFT calculations. Expand
Carbon Dioxide Capture by Aqueous Ionic Liquid Solutions.
Three types of CO2 sorption in aqueous solutions of imidazolium-based ionic liquids associated with acetate andImidazolate anions react reversibly with CO2 to yield bicarbonate, with sorption values higher than the classical alkanol amines or even alkaline aqueously solutions under similar experimental conditions.

Stereochemical dependence of NMR geminal spin–spin coupling constants
This work sought to explore the versatility of geminal spin–spin coupling constants, 2JXY SSCCs, as probes for stereochemical studies by calculating hyperconjugative interactions within the Natural Bond Orbital approach. Expand
Organocatalytic Imidazolium Ionic Liquids H/D Exchange Catalysts.
Detailed kinetic experiments demonstrate that the reaction is first order on the substrate and pseudozero order relative to the ionic liquid, due to the fast reversible reaction involving the deuteration of the ionsic liquid by the solvent. Expand
Analysis of the electronic origin of the 1JCH spin-spin coupling trend in 1-X-cyclopropanes: experimental and DFT study.
In this work, several 1-X-cyclopropane derivatives are taken as model compounds to apply such ideas to rationalize substituent effects on the Fermi contact term of 1JC1,H spin-spin coupling. Expand
The effect of carbonyl group in the asymmetry of 3, 4JCH coupling constants in norbornanones
Theoretical and experimental studies of 3, 4JCH couplings were carried out in 3‐endo‐ and 3‐exo‐X‐2‐norbornanone derivatives and in exo‐ and endo‐ 2‐noborneol compounds to study hyperconjugative interactions involving the carbonyl group. Expand
Dealing with supramolecular structure for ionic liquids: a DOSY NMR approach.
In the particular case of 1,2,3-trimethylimidazolium imidazolate containing confined water in DMSO the maintenance of the contact ion pairs depends on the water content which may even disrupt the IL supramolecular structure. Expand
