The Curious Concept That Almost Nobody Seemed to Care About at First: Virtual Particles in the Post‐War Period**

Berichte zur Wissenschaftsgeschichte, EarlyView.
Abstract Short‐lived, unobservable, and not subject to the usual rules of conservation of energy and momentum, virtual particles—an integral part of the conceptual framework of quantum field theory (QFT)—exhibit a number of curious characteristics which, in recent decades, have in part fueled important discussions about their ontological status ...

Detergent/surfactant retention during ultrafiltration in the formulation of biotherapeutics

Biotechnology Progress, EarlyView.
Abstract Surfactants like polysorbate (Tween®) are commonly used as excipients in the production of monoclonal antibodies and other recombinant proteins. The retention behavior of these excipients in the final ultrafiltration step can be difficult to predict due to the presence of both monomers and micelles.

Selective Light‐Driven CO2 to CO Reduction by a [FeFe]‐Hydrogenase Mimic in Water

ChemCatChem, EarlyView.
Highly selective light‐driven CO2 conversion to CO is achieved using an [FeFe]‐hydrogenase‐inspired molecular dyad (PS‐CAT) acting simultaneously as photosensitizer and catalyst. The presence of water as a solvent is important for such selectivity. Assembling the PS‐CAT in the hydrophobic part of lipid bilayers of liposomes allows the use of water as a

In Situ Raman Spectroscopic Studies on Iron‐Based Catalysts During CO2 Fischer–Tropsch Synthesis

ChemCatChem, EarlyView.
Raman spectroscopy was employed to monitor iron‐catalzyed CO2‐Fischer–Tropsch synthesis toward higher hydrocarbons with alkali metal‐doped ferrous oxalate as precatalyst. The thermal transformation of MFeC2O4 into Fe3O4 as the major phase did not show a significant dependency on the presence and type of alkali metal dopant.
