Influence of Ligand Design and Non‐Covalent Interactions on the Isoselective Ring‐Opening Polymerization of rac‐ß‐Butyrolactone using Salan and Salalen Rare‐Earth Metal Catalysts

Angewandte Chemie International Edition, Accepted Article.
We herein report the influence of the ligand framework on the isoselective ring‐opening polymerization (ROP) of rac‐β‐butyrolactone using highly active in situ generated salan [ONNO]H2 and salalen [ONNO]H rare‐earth metal complexes. The stereochemistry was found to be highly dependent on the ortho‐substituents, enabling the synthesis of either ...

Stratification in steelmaking ladles [PDF]

, 1993
The problem of temperature stratification in a steelmaking ladle is considered. There are three distinct zones in the flow, the wall boundary layer, the bottom stagnation zone and the central plug flow.

Long‐Lasting Hydrophilicity Induced by Ultraviolet Light on Surface Modified Hydrophobic Polylactic Acid

Journal of Applied Polymer Science, EarlyView.
In light of increasing applications of compostable materials, surface treatment on PLA to increase roughness and hydrophobicity has been investigated. However, modifying wettability might hinder degradation. UVC exposure has significant effects on the wettability of textured PLA substrates, allowing a complete wettability switch due to chain scission ...

Particle Acceleration via Transient Stagnation Surfaces in MADs During Flux Eruptions [PDF]

arXiv
In this study, we focus on the simulation of accretion processes in Magnetically Arrested Disks (MADs) and investigate the dynamics of plasma during flux eruption events. We employ general relativistic magneto-hydrodynamic (GRMHD) simulations and search for regions with a divergent velocity during a flux eruption event. These regions would experience

Group classification of steady two-dimensional boundary-layer stagnation-point flow equations [PDF]

arXiv, 2010
Lie symmetry group method is applied to study the boundary-layer equations for two-dimensional steady flow of an incompressible, viscous fluid near a stagnation point at a heated stretching sheet placed in a porous medium equation. The symmetry group and its optimal system are given, and group invariant solutions associated to the symmetries are ...
