Synthetic Lignin Oligomers: Analytical Techniques, Challenges, and Opportunities

open access: yesChemSusChem, EarlyView.
The review begins by discussing lignin and its structural complexity, followed by challenges in elucidating depolymerization products and the analytical techniques used. It then focuses on the chemical structure of synthetic lignin oligomers, their synthesis mechanisms, and their significance in current science. Finally, scientific gaps are identified,

Scalable Mechanochemical Synthesis of Biotin[6]uril

open access: yesChemSusChem, EarlyView.
Macrocycle up‐scaled: Practical mechanochemical synthesis for the preparation of biotin[6]uril in decagram quantities from d‐biotin. Reaction was scaled up 82‐fold from shaker to planetary mill. Developed approach offers significant advantages over the solution‐based method, including higher yields, a reduction in reaction time, more straightforward ...

Rethinking Chlorine: Essential Chemical or Replaceable Risk?

open access: yesChemSusChem, Accepted Article.
This review critically examines the dual nature of chlorine as both an indispensable base chemical and a potential risk. Chlorine and its by‐product hydrogen chloride play essential roles in the production of pharmaceuticals, plastics, agrochemicals, and disinfectants.

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

open access: yesChemSusChem, Accepted Article.
Zinc is a non‐toxic and readily available metal whose complexes have been extensively studied as catalysts for the ring opening polymerization of lactide to poly(lactic acid). When employed in polymerization of racemic lactide, zinc‐based catalysts are typically found to be non‐stereoselective and the desired isoselective catalysts are particularly ...

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 ...
