Poly(dichlorophosphazene) synthesis via Me3Si─N═PCl3 polymerization was reinvestigated using quantum chemical calculations and experiments. A cationic initiator (Ph3PCl2) enables ambient‐temperature polymerization through chloride‐catalyzed cationic pathways involving dissociation, nucleophilic chloride attack, and chain‐propagating species formation ...

Getting the Big Ones to Pack: Crystal Structure of Vitamin K2 With a Chaperone
A method for obtaining co‐crystals of medium‐size organic molecules and ‐tetrakis(2‐fluoro‐4‐methoxyphenyl)adamantane (TFM) as chaperone was developed. This method yielded a high‐resolution x‐ray crystal structure of menaquinone MK‐4 (vitamin K2), in which layers of chaperone and vitamin guest molecules are found.

Automated Process Optimization in a Novel Triple Shaft Mixer with Adaptive Mixing Modes
A novel multi‐purpose mixer with adjustable blade angle and a coaxial stirrer is developed, providing three degrees of freedom. An optimization strategy is integrated to autonomously identify optimal operating conditions through automated tests. The current draw of the main stirrer serves as the optimization criterion, while stirrer speeds, directions,
