Optical materials and structures

Optical materials and structures are substances used to manipulate the flow of light. This can include reflecting, absorbing, focusing or splitting an optical beam. The efficiency of a specific material at each task is strongly wavelength dependent, thus a full understanding of the interaction between light and matter is vital.

    Development of simple uranyl recognition motifs possessing siderophore-like binding strength and selectivity presents a challenge. Here the authors show a comprehensive theoretical and experimental study on uranyl binding with a polymeric adsorbent material decorated with a non-toxic siderophore inspired small molecule chelator.

    Copper on ceria is an excellent catalyst for the low-temperature water–gas shift reaction. Here the active sites are directly imaged by electron microscopy and probed with in situ spectroscopy, showing that the reaction proceeds via a cooperative mechanism whereby the Cu+ chemically adsorbs CO while an adjacent Ov–Ce3+ site dissociatively activates H2O.
