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 ... -
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
(Elsevier, 2021-02-22)In this work, we studied the composition-dependent miscibility of polyamide 6 and biobased polyamide 4,10 (PA6/PA410) blends, as triggered by crystallization driven phase segregation. The blends were prepared by extrusion ... -
Confined Crystallization of Polymers within Nanopores
(ACS, 2021-08-03)Crystallization of polymeric materials under nanoscopic confinement is highly relevant for nanotechnology applications. When a polymer is confined within rigid nanoporous anodic aluminum oxide (AAO) templates, the ... -
Controlling the Isothermal Crystallization of Isodimorphic PBS-ran-PCL Random Copolymers by Varying Composition and Supercooling
(MDPI, 2019-12-20)In this work, we study for the first time, the isothermal crystallization behavior of isodimorphic random poly(butylene succinate)-ran-poly(ε-caprolactone) copolyesters, PBS-ran-PCL, previously synthesized by us. We perform ... -
Correlation between Grafting Density and Confined Crystallization Behavior of Polyethylene Glycol Grafted to Silica
(American Chemical Society, 2019-02-06)The interfacial interactions of polymer-nanoparticles have dramatical effects on the crystallization behavior of grafted polymers. In this study, methoxy polyethylene glycol (MPEG) (molecular weights 750, 2000 and 4000 g ... -
Crystallization and self-nucleation of PLA, PBS and PCL in their immiscible binary and ternary blends
(Elservier, 2019-06-13)Three semicrystalline polyesters, poly(lactic acid), poly(caprolactone) and poly(butylene succinate) (PLA, PCL and PBS) were melt blended to prepare binary and ternary systems of selected compositions. In binary blends ... -
Crystallization and Stereocomplexation of PLA-mb-PBS Multi-Block Copolymers
(MDPI, 2017-12-22)The crystallization and morphology of PLA-mb-PBS copolymers and their corresponding stereocomplexes were studied. The effect of flexible blocks (i.e., polybutylene succinate, PBS) on the crystallization of the copolymers ... -
Crystallization Kinetics and Nanoparticle Ordering in Semicrystalline Polymer Nanocomposites
(Elsevier, 2022-03-13)There has been considerable interest in the nucleation and crystallization of polymers in the presence of nanoparticles (NPs, or nanofillers in general, NFs). Most of the extensive work in this area has focused on anisotropic, ... -
Crystallization of isodimorphic aliphatic random copolyesters: pseudo-eutectic behavior and double-crystalline materials
(Elservier, 2018-02-28)Isodimorphic random copolyesters are intriguing polymeric materials that can crystallize in their entire composition range, despite the random distribution of comonomer units along their chains. This behavior stems from ... -
