Cascading energy transfer to extend the photochromic activation range of a donor-acceptor Stenhouse adduct

Donor-acceptor Stenhouse adducts (DASA) are a class of compounds that have been of great interest in the last decade, particularly due to their efficient negative photochromic properties, their short-step synthesis and their very high molar…

Multilayered meta scintillator with thermally deposited organic active and metal halide dielectric layers

Classic bulk scintillation organic and inorganic have two intrinsic limitations: The scintillation light emission is isotropic, hindering efficient light collection. Scintillation decay time are directed by the slowest emitters in the scintillators,…

Influence of water and humidity on oil paint layers: Mechanisms of uptake, swelling, and consequences for chemical and mechanical stability

Historical paintings are complex multilayered and dynamic systems whose stability is strongly influenced by environmental conditions. In recent years, growing attention has been directed towards the impact of water exposure on oil paints, as a…

Persistence without turnover: the RhoG G12E mutant highlights the role of nucleotide cycling in RhoG signaling

Abstract Small GTPases of the Ras superfamily act as molecular switches cycling between GDP-bound inactive and GTP-bound active states. Their signaling output depends not only on GTP loading but on continuous nucleotide cycling controlled by guanine…
