The Low Oxidation State Paradigm is more Consistent with XFEL Observations of the S₃ → [S₄] → S₀ Transition in Photosystem II

open access: yesChemistry – A European Journal, Accepted Article.
Photosynthetic water splitting catalyzed by the Mn4CaO5/6 cluster in the oxygen‐evolving complex (OEC) of photosystem II (PSII) is crucial for sustaining the supply of oxygen on Earth. A recent serial femtosecond X‐ray crystallography (XFEL) study has provided unprecedented insights into the structural dynamics of the OEC during the S₃ → [S₄] → S₀ ...

Functionalization, Fragmentation, and Expansion of cyclo‐P4R2 Ligands

open access: yesChemistry – A European Journal, EarlyView.
Three isolobal transition metal (TM) units are demonstrated to impact the transformation of coordinated P4 ligands in different ways. The observed reactivity primarily depends on the nature of the TM, an effect so far underexplored in phosphorus chemistry. This in‐depth analysis shines light on the underlying mechanistic principles and exploits them to

Synthesis and Reactivity of Triphosphaallyl Cation Stabilized by N‐Heterocyclic Carbenes

open access: yesChemistry – A European Journal, EarlyView.
Imidazoliumyl‐substituted triphosphaallyl cations undergo selective P–C bond cleavage and form unprecedented bicyclic P₃‐Ga scaffolds with unique reactivity. Abstract Reduction of the triphosphaallyl species 6[GaCl4] with GaI[Ga2Cl7] affords the imidazoliumyl‐substituted (L) bicyclo[2.1.1]‐triphosphane 10[Ga2Cl7], featuring an unprecedented Ga2Cl5 ...

Effect of NaOH Steam on Swelling and Cleaning of Food Soil Layers

open access: yesChemie Ingenieur Technik, EarlyView.
The effects of steam and NaOH steam, in comparison with water and sodium hydroxide, on the swelling behavior and removal forces of three food‐based soils were investigated. Comparative cleaning experiments were performed using these food soils after pre‐swelling with NaOH steam, steam, NaOH, or water.

Optimal control of axial dispersion tubular reactors with recycle: Addressing state‐delay through transport PDEs

open access: yesThe Canadian Journal of Chemical Engineering, EarlyView.
The boundary‐regulated distributed parameter system of an axial dispersion tubular reactor with delayed recycle is showcased, along with the optimal observer‐based control strategy developed using a late‐lumping method for its stabilization. Abstract The optimal control of an axial tubular reactor with a recycle stream is addressed as a key type of ...
