AuSin − (n = 4−12) clusters were produced with a laser vaporization source and investigated by photoelectron spectroscopy. The swarm-intelligence-based CALYPSO structure search method and ab initio calculations were employed to determine their ground-state structures. The results revealed that the most stable isomers of AuSin − (n = 4−12) cluster anions are all exohedral structures, in which th...

Interfaces between organic molecules and solid surfaces play a prominent role in heterogeneous catalysis, molecular sensors and switches, light-emitting diodes, and photovoltaics. The properties and the ensuing function of such hybrid interfaces often depend exponentially on molecular adsorption heights and binding strengths, calling for well-established benchmarks of these two quantities. Here...

Die studies show that this gigantic amount so-called mix, had been used produce...

To operate with (or in, or from) the discipline of cybernetics is to engage with the concepts and guides-to-action elucidated by Heinz von Foerster. It is impossible for us to do otherwise, because his work ““stands under”” the praxis of circular-causal reasoning, second-order thinking-acting, and ethical viewpoints. Elucidate is a fitting word because it comes from a root meaning to shine a li...
