The Height of Chitinous Ridges Alone Produces the Entire Structural Color Palette

The colorful wings of butterflies result from the interaction between light and the intricate chitinous nanostructures on butterflies’ scales. This study demonstrates that just by reproducing the chitinous ridges present in butterfly scales (i.e., without ...

Bi-stable spin-crossover in charge-neutral [Fe(R-ptp)(2)] (ptp=2-(1H-pyrazol-1-yl)-6-(1H-tetrazol-5-yl)pyridine) complexes

Sergio Vela Llausi

Bi-stable charge-neutral iron(II) spin-crossover (SCO) complexes are a class of switchable molecular materials proposed for molecule-based switching and memory applications. In this study, we report on the SCO behavior of a series of iron(II) complexes com ...

Density effects on solute release from the streambed

David Andrew Barry

Contaminants can be released to the stream from the bed by previous pollution events. The releasing contaminants may cause secondary pollution for a river, which impacts the river’s eco-environmental condition. By means of laboratory experiments and numeri ...

Stability profiles of transition metal oxides in the oxygen evolution reaction in alkaline medium

Xile Hu, Aliki Moysiadou

The electrochemical water splitting reaction can convert renewable electricity into clean hydrogen fuel. The efficiency of water splitting is limited to a large extent by the sluggish oxygen evolution reaction (OER). Numerous transition metal oxides have b ...
