How Aromatic Are Molecular Nanorings? The Case of a Six-Porphyrin Nanoring**
(Wiley, 2021-11-02)
Large conjugated rings with persistent currents are novel promising structures in molecular-scale electronics. A six-porphyrin nanoring structure that allegedly sustained an aromatic ring current involving 78 pi electrons ...
Acoustic plasmons in extrinsic free-standing graphene
(IOP Publishing, 2014-08-04)
An acoustic plasmon is predicted to occur, in addition to the conventional two-dimensional (2D) plasmon, as the collective motion of a system of two types of electronic carriers coexisting in the same 2D band of extrinsic ...
Advances in Single-Chain Nanoparticles for Catalysis Applications
(MDPI, 2017-10-21)
Enzymes are the most efficient catalysts known for working in an aqueous environment near room temperature. The folding of individual polymer chains to functional single-chain nanoparticles (SCNPs) offers many opportunities ...
Efficient Synthesis of Single-Chain Polymer Nanoparticles via Amide Formation
(Hindawi Publishing, 2015)
Single-chain technology (SCT) allows the transformation of individual polymer chains to folded/collapsed unimolecular soft nanoparticles. In this work we contribute to the enlargement of the SCT toolbox by demonstrating ...
Dynamics of aqueous peptide solutions in folded and disordered states examined by dynamic light scattering and dielectric spectroscopy
(Royal Society of Chemistry, 2021-06-24)
[EN] Characterizing the segmental dynamics of proteins, and intrinsically disordered proteins in particular, is a challenge in biophysics. In this study, by combining data from broadband dielectric spectroscopy (BDS) and ...
Motions of Water and Solutes-Slaving Versus Plasticization Phenomena
(American Institute of Physics, 2019-03-28)
It is well-accepted that hydration water is crucial for the structure, dynamics, and function of proteins. However, the exact role of water for the motions and functions of proteins is still debated. Experiments have shown ...
Advances in Fluorescent Single-Chain Nanoparticles
(MDPI, 2017-10-26)
Fluorophore molecules can be monitored by fluorescence spectroscopy and microscopy, which are highly useful and widely used techniques in cell biology, biochemistry, and medicine (e.g., biomarker analysis, immunoassays, ...
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 ...
Advances in the Phototriggered Synthesis of Single-Chain Polymer Nanoparticles
(MDPI, 2019-11)
Clean use of photons from light to activate chemical reactions offers many possibilities in different fields, from chemistry and biology to materials science and medicine. This review article describes the advances carried ...
Glass-Transition Dynamics of Mixtures of Linear Poly(Vinyl Methyl Ether) with Single-Chain Polymer Nanoparticles: Evidence of a New Type of Nanocomposite Materials
(MDPI, 2019-03-21)
Single-chain polymer nanoparticles (SCNPs) obtained through chain collapse by intramolecular cross-linking are attracting increasing interest as components of all-polymer nanocomposites, among other applications. We present ...
