Highly Isoselective Polymerization of rac‐Lactide by Zinc Complexes of Sequential Tetradentate {ONNN} Ligands

open access: yesChemSusChem, EarlyView.
Zinc complexes of a new family of sequential {ONNN} ligands are introduced and employed for the ring‐opening polymerization of rac‐lactide. The pyridine‐amine‐imine‐phenolate complexes lead to a rare combination of very high activities and isoselectivities yielding stereomultiblock poly(lactic acid) while their isomers are less active and essentially ...

On the Density–Density Correlations of the Non‐Interacting Finite Temperature Electron Gas

open access: yesContributions to Plasma Physics, EarlyView.
ABSTRACT The density–density correlations of the non‐interacting finite temperature electron gas are discussed in detail. Starting from the ideal linear density response function and utilizing general relations from linear response theory, known and novel expressions are derived for the pair correlation function, static structure factor, dynamic ...

Ionization Potential Depression and Fermi Barrier in Warm Dense Matter: A First‐Principles Approach

open access: yesContributions to Plasma Physics, EarlyView.
ABSTRACT Ionization potential depression (IPD) is of crucial importance to understand and accurately predict the properties of dense, partially ionized plasmas. Many models of IPD have been developed that, however, exhibit largely varying results. Recently, a novel approach was proposed that is based on first‐principles quantum Monte Carlo simulations ...

Modelling Thomson Scattering in a Hydrogen Plasma at Stellar Interior Conditions Using the Hypernetted‐Chain Approach

open access: yesContributions to Plasma Physics, EarlyView.
ABSTRACT Under the extreme conditions found in small stars, where electron degeneracy and Coulomb coupling are significant, accurate modeling of Thomson scattering is crucial for determining opacity, a primary quantity for stellar energy transport.
