Chemistry – A European Journal, EarlyView.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
Chemistry – A European Journal, EarlyView.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
Chemie Ingenieur Technik, EarlyView.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,

Review of CFD modelling techniques for single‐phase and multiphase flow in static mixers
The Canadian Journal of Chemical Engineering, EarlyView.This review synthesizes computational fluid dynamics (CFD) approaches for static mixers, linking hydrodynamics to pressure drop, particle/droplet distributions, mixing metrics, and heat‐transfer performance to guide modelling choices and design decisions. Abstract Static mixers enable compact and low‐energy intensification.

Investigating the Cytoskeleton of DRGs Using Cryo‐Electron Microscopy and Deep Learning
Cytoskeleton, EarlyView.ABSTRACT We describe a method for determining the ultrastructural organization of axons and varicosities of cultured dorsal root ganglion (DRG) neurons using cryogenic electron microscopy (cryo‐EM). Cryo‐EM reveals the dimensions, proximity, and overall organization of biological specimens in a near‐native state, avoiding artifacts of fixation and ...
