An Agonist/Antagonist Photo‐Switchable Vitamin D Mimetic Enables Bidirectional Optical Control of VDR

open access: yesAngewandte Chemie International Edition, EarlyView.
Vitamin D exhibits complex and cell‐specific biological effects in multiple tissues via activation of the ligand‐sensing transcription factor vitamin D receptor (VDR). The photo‐switchable vitamin D mimetic 10 transitions between VDR antagonist (E) and agonist (Z) activity upon illumination and offers unprecedented bidirectional optical control over ...

Overcrowded Alkene Photo‐Redox‐Switches Based on Quinolinium/Carbene Building Blocks

open access: yesAngewandte Chemie International Edition, EarlyView.
A modular synthesis of a new class of photo‐ and redox‐switches is described based on the combination of quinolinium salts and carbenes. Photochemical switching allows to selectively switch between folded E/Z isomers, while electrochemical switching allows to change between neutral, radical cation and dicationic oxidation states, which are all isolable

Eco‐Friendly Aqueous Polymeric Binders for High‐Performance Graphite Anodes: Structure–Property Insights for Lithium‐Ion Batteries

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Polyvinylidene fluoride (PVdF) is commonly used as a binder material in the preparation of anode or cathode electrode slurries for commercial Li‐ion batteries (LIBs). High‐cost PVdF binder generally requires the use of toxic and environmentally unfriendly N‐methyl‐2‐pyrrolidone (NMP) as a solvent for dissolution.

Catalytic Pyrolysis of Waste Polystyrene Over Fe–B Composite Catalyst for Enhanced Liquid Fuel Production

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Healthcare derived polystyrene waste represents a growing and under addressed fraction of plastic waste streams due to contamination risks and limited recyclability. This study aims to investigate the valorization of waste polystyrene foam through catalytic and noncatalytic pyrolysis pathways to evaluate product yield distribution and identify
