Brownian Dynamics Computational Model of Protein Diffusion in Crowded Media with Dextran Macromolecules as Obstacles
(MDPI, 2017-03-09)The high concentration of macromolecules (i.e., macromolecular crowding) in cellular environments leads to large quantitative effects on the dynamic and equilibrium biological properties. These effects have been experimentally ... -
Catechol End-Functionalized Polylactide by Organocatalyzed Ring-Opening Polymerization
(MDPI, 2018-02-06)There is a great interest in incorporating catechol moieties into polymers in a controlled manner due to their interesting properties, such as the promotion of adhesion, redox activity or bioactivity. One possibility is ... -
Catechol-containing acrylic Poly(ionic liquid) Hydrogels as Bioinspired Filters for Water Decontamination
(ACS, 2019-06-13)Mussel inspired catechol containing materials have currently drawn great attention as biomaterials, adhesives, surface coating and in bioelectronics, among other applications. In this work, we mimicked the ability of mussels ... -
Cation Effect in the Corrosion Inhibition Properties of Coumarate Ionic Liquids and Acrylic UV-Coatings
(MDPI, 2020-11-06)Chromate free corrosion inhibitors are searched for to mitigate the economic loss caused by mid-steel corrosion. Here, we show metal-free organic inhibitors having free coumarate anions that can be used either as direct ... -
Cellulose as an Inert Scaffold in Plasmon-Assisted Photoregeneration of Cofactor Molecules
(American Chemical Society, 2020-04-29)Plasmonic nanoparticles exhibit excellent light-harvesting properties in the visible spectral range, which makes them a convenient material for the conversion of light into useful chemical fuel. However, the need for using ... -
Chemical Structure Drives Memory Effects in the Crystallization of Homopolymers
(ACS, 2020-06-11)Although the study of melt memory has attracted much interest, the effect of polymer chemical structure on its origin has not been fully elucidated. In this work, we study melt memory effects by Differential Scanning ... -
Classical Force-Field Parameters for CsPbBr3 Perovskite Nanocrystals
(American Chemical Society, 2022-07-16)Understanding the chemico-physical properties of colloidal semiconductor nanocrystals (NCs) requires exploration of the dynamic processes occurring at the NC surfaces, in particular at the ligand-NC interface. Classical ... -
CO2 revalorization for the organocatalytic synthesis of cyclic carbonates and vanillin-based non-isocyanate polyurethanes (NIPUSs).

Collective Motions and Mechanical Response of a Bulk of Single-Chain Nano-Particles Synthesized by Click-Chemistry
(MDPI, 2020-12-25)We investigate the effect of intra-molecular cross-links on the properties of polymer bulks. To do this, we apply a combination of thermal, rheological, diffraction, and neutron spin echo experiments covering the inter-molecular ... -
Competition between Chain Extension and Crosslinking in Polyamide 1012 during High Temperature Thermal Treatments as Revealed by SSA Fractionation
(ACS, 2021-08-03)Self-nucleation and annealing (SSA) is an efficient way to thermally fractionate semi-crystalline polymers. The thermal fractions produced by SSA have distinct melting points that correspond to different average lamellar ... -
Competition between nucleation and confinement in the crystallization of poly(ethylene glycol)/ large aspect ratio hectorite nanocomposites
(Elsevier Ltd, 2020-06-25)The overall crystallization kinetics of polymer nanocomposites is determined by nucleation and crystal growth, which are both greatly affected by confinement. Heterogeneous nucleation is influenced by the interphase area ... -
Competitive binding of HIF-1α and CITED2 to the TAZ1 domain of CBP from molecular simulations
(RSC, 2020-04-03)Many intrinsically disordered proteins (IDPs) are involved in complex signalling networks inside the cell. Their particular binding modes elicit different types of responses that can be subtly regulated. Here we study the ... -
Composition Dependent Miscibility in the Crystalline State of Polyamide 6 /Polyamide 4,10 Blends: from Single to Double Crystalline Blends
