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

open access: yesBerichte 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 ...

Einstein against quantum mechanics: randomness, ignorance and our ignorance about randomness [PDF]

open access: yesarXiv, 2007
Albert Einstein made fundamental contributions to the development of quantum mechanics. However, he was never satisfied with the quantum worldview. In fact, during most of his life he attempted to find inconsistencies and paradoxes within quantum mechanics.

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

open access: yesChemCatChem, 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
