Effect of Chain Stereoconfiguration on Poly(3-hydroxybutyrate) Crystallization Kinetics
(American Chemical Society, 2022-08)
Poly(3-hydroxybutyrate) (PHB) is naturally accumulated by bacteria but can also be synthesized chemically. Its processability is limited, as it tends to degrade at temperatures above its melting temperature; hence, ...
Surface Nucleation of Dispersed Droplets in Double Semicrystalline Immiscible Blends with Different Matrices
(Wiley, 2022-11)
When a minor semicrystalline phase is dispersed in an immiscible blend with another polymer in the form of isolated droplets, its crystallization behavior is dominated by nucleation. In particular, nucleation can occur in ...
Tailoring magnetism in silicon-doped zigzag graphene edges
(Nature, 2022)
Recently, the edges of single-layer graphene have been experimentally doped with silicon atoms by means of scanning transmission electron microscopy. In this work, density functional theory is applied to model and characterize ...
Molecular nanoribbon gels
(Royal Society of Chemistry, 2022-08)
Herein, we show that twisted molecular nanoribbons with as many as 322 atoms in the aromatic core are efficient gelators capable of self-assembling into ordered pi-gels with morphologies and sol-gel transitions that vary ...
Natural Deep Eutectic Solvents Based on Choline Chloride and Phenolic Compounds as Efficient Bioadhesives and Corrosion Protectors
(American Chemical Society, 2022)
[EN] Natural deep eutectics solvents (NADES), owing to their high solvation capacity and nontoxicity, are actively being sought for many technological applications. Herein, we report a series of novel NADES based on choline ...
Self-healable dynamic poly(urea-urethane) gel electrolyte for lithium batteries
(Royal Society of Chemistry, 2022)
[EN] Self-healing materials are actively studied in order to extend the lifetime and performance of batteries. Dynamic covalent networks have recently emerged as one of the best self-healable materials which allow thermosets ...
(PVDF)2(PEO)2 miktoarm star copolymers: Synthesis and isothermal crystallization leading to exclusive β-phase formation
(Elsevier, 2022-10)
In this work, we study how chain topology can induce different polymorphic behaviors in poly(vinylidene fluoride) (PVDF)-based materials. A linear PVDF precursor with two azido groups at the junction point, (PVDFx-N3)2 and ...
Enhanced and Reusable Poly(hydroxy urethane)-Based Low Temperature Hot-Melt Adhesives
(American Chemical Society, 2022)
[EN] Poly(hydroxy urethane)s (PHUs) based on 5-membered cyclic carbonates have emerged as sustainable alternatives to conventional isocyanate-based polyurethanes. However, while from the point of view of sustainability ...
Experiment and Theory Clarify: Sc+ Receives One Oxygen Atom from SO2 to Form ScO+, which Proves to be a Catalyst for the Hidden Oxygen-Exchange with SO2
(Wiley, 2022-03-04)
[EN] Using Fourier-transform ion cyclotron resonance mass spectrometry, it was experimentally determined that Sc+ in the highly diluted gas phase reacts with SO2 to form ScO+ and SO. By O-18 labeling, ScO+ was shown to ...
Stars, combs and bottlebrushes of elastic single-chain nanoparticles
(Elsevier, 2022-10)
Hierarchical self-assembly of structural elements gives rise to superstructures often with outstanding properties when compared to individual elements, as first observed in nature. While folding of individual synthetic ...
