Advanced Functional Materials, EarlyView.Copper catalysts introduced with different non‐metallic elements regulating the coordination number of Cu are prepared by magnetron sputtering. Reducing the Cu coordination number enhances C─C coupling and boosts C2+ product selectivity, by lowering the energy barrier for the *CO → *CHO conversion step. The optimized Si‐doped Cu catalyst achieves a C2+

Side Reaction Pathway Modulation for Hydrogen Evolution‐Free Aqueous Zn‐Ion Batteries
Advanced Functional Materials, EarlyView.A ZnO–TeO2–Te ternary composite layer with a unique rice grain‐like morphology is spontaneously formed on the Zn anode via telluric acid additive. This functional interphase effectively suppresses side reactions such as zinc hydroxide sulfate formation, hydrogen evolution, and Zn corrosion, enabling highly reversible and stable Zn metal cycling in ...

Multiple global radiations in tadpole shrimps challenge the concept of ‘living fossils’
PeerJ, 2013 ‘Living fossils’, a phrase first coined by Darwin, are defined as species with limited recent diversification and high morphological stasis over long periods of evolutionary time.

Nature, 1922 WHEN we examine a catalogue of fossil plants, such as that for North America recently published by Knowlton, we are struck by the enormous number of recorded species, and readily receive the impression that the flora of former ages is quite well known.
