Peptide self‐assembled nanostructures: from models to therapeutic peptides
Get PDF: Self-assembly is the most suitable approach to obtaining peptide-based materials on the nano- and mesoscopic scales. Applications span from peptide drugs for personalized therapy to light harvesting and electron conductive media for solar energy production and bioelectronics, respectively. In this study, we will discuss the self-assembly of selected model and bioactive peptides, in particular reviewing our recent work on the formation of peptide architectures of nano- and mesoscopic size in solution and on solid substrates. The hierarchical and cooperative characters of peptide self-assembly will be highlighted, focusing on the structural and dynamical properties of the peptide building blocks and on the nature of the intermolecular interactions driving the aggregation phenomena in a given environment. These results will pave the way for the understanding of the still-debated mechanism of action of an antimicrobial peptide (trichogin GA IV) and the pharmacokinetic properties of a peptide drug (semaglutide) currently in use for the therapy of type-II diabetes

Second-order corrections to transport coefficients of binary gaseous mixtures: N2 with He, Ne and Ar
No full textThe usual kinetic theory of dilute gaseous mixtures is employed, via the infinite‐order sudden (IOS) decoupling scheme for the dynamics, to obtain generalized collision integrals and transport properties for molecular mixtures containing N2 and various rare gases (He, Ne, and Ar). The relevant interaction potentials originate from a previous study [F. A. Gianturco, M. Venanzi, and A. S. Dickinson, Mol. Phys. 6 5, 563 (1988)] of the above systems in which a multiproperty analysis of their quality and reliability was attempted by combining scattering data, when available, with diffusion coefficients and interaction viscosity data to select the most accurate of the potential energy surfaces (PES) at hand. The extension of the calculations to second‐order effects allows us to test the importance of such corrections on diffusion and viscosity coefficients, to follow their dependence on the mole fraction of the mixtures, to obtain thermal diffusion and thermal conductivity results and to futher assess the feasibility of multiproperty tests of simple atom–diatom interactions via the calculation of a broader range of transport coefficients
