Abstract We assess the crucial role of tetrapyrrole flexibility in CO ligation to distinct Ru‐porphyrins supported on an atomistically well‐defined Ag(111) substrate. Our systematic real‐space visualisation and manipulation experiments with scanning tunnelling microscopy directly probe ligation, while bond‐resolving atomic force X‐ray standing‐wave measurements characterise geometry, ultraviole...

In the eggs of the newt, Triturus pyrrhogaster, 2 separate factors are recognized which take part in cleavage furrow formation. (1) The inductive capacity for the furrow formation by the cytoplasm lying under the cortex along the cleavage furrow (FIC); and (2) the reactivity of the overlying cortex to form a furrow in response to FIC. (1) FIC. The inductive capacity is shown by the fact that FI...

[Reaction: see text]. A solid understanding of the mechanisms involved in heterogeneously catalyzed reactions is of fundamental interest for modern chemistry. This information can help to refine modern theories of catalysis and, in a very practical way, can help researchers to optimize existing industrial processes and develop new ones. To understand the mechanisms of heterogeneous catalysis, w...

In the Theory of Challenge and Threat States in Athletes (TCTSA) it is proposed that on approach to motivated performance situations an individual can respond in a challenge state or a threat state. Challenge and threat states are marked by contrasting patterns of psychological, emotional, and cardiovascular (CV) responses. A challenge state is proposed to maintain or facilitate performance com...
