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 ...
Lewis Acid Properties of Tetrel Tetrafluorides—The Coincidence of the -Hole Concept with the QTAIM Approach
(MDPI, 2017-02)
Tetrel bond is analysed for a series of ZF(4) (Z = C, Si, Ge) complexes with one and two NH3 or AsH3 ligands. The MP2/aug-cc-pVTZ calculations were performed and supported by results of the Quantum Theory of Atoms in ...
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 ...
Enantioselective Ring-Opening Polymerization of rac-Lactide Dictated by Densely Substituted Aminoacids
(ACS, 2017-03-08)
Organocatalysis is becoming an important tool in
polymer science because of its versatility and specificity. To date
a limited number of organic catalysts have demonstrated the
ability to promote stereocontrolled ...
Temperature responsive PEG-based polyurethanes “ a la carte”
(Elsevier, 2017-06-22)
Temperature responsive polymers able to alter their chemical or physical properties have been extensively
investigated. Most of these polymers have an alkane polymer backbone with only carbon-carbon
bonds. In this sense, ...
Non-Isocyanate Polyurethane Soft Nanoparticles Obtained by Surfactant-Assisted Interfacial Polymerization
(ACS, 2017-01-24)
Polyurethanes (PUs) are considered ideal candidates for drug delivery applications due to their easy synthesis, excellent mechanical properties, and biodegradability. Unfortunately, methods for preparing well-defined PU ...
Aluminum's preferential binding site in proteins: sidechain of amino acids versus backbone interactions
(Elsevier, 2017-11-11)
The interaction of aluminum ion Al(III) with polypeptides is a subject of paramount importance, since it is a central feature to understand its deleterious effects in biological systems. Various drastic effects have been ...
