Optical materials and structures

Definition

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.

    Nanostructures with atomic-level thicknesses have the potential to exhibit unique size-dependent properties. Here the authors fabricate sulfur-doped molybdenum oxide architectures with tunable ring-in-ring morphologies and strong visible- and IR-light absorption, endowing them with a range of photoresponsive properties.

    Ice crystal growth is a major problem in cell and tissue cryopreservation for transplantation, transfusion, icing of aircraft wings and many other applications. Here the authors review the emerging field of synthetic macromolecular mimics of antifreeze proteins that can be used overcome such problems.

    Doping metal nanoclusters at specific sites is a powerful strategy for tuning their properties. Here, the authors precisely control the alloying sites of bimetallic nanoclusters by replacing entire surface motifs with structurally similar heteroatom motifs, tuning the surface composition motif-by-motif rather than atom-by-atom.

    Here, the authors report a graphene-silica assembly which could be coated onto a nickel-rich cathode via a scalable process for considerably improved electrochemical performance. In the presence of such graphene balls, a full cell benefits from an increased volumetric energy density by 27.6%.

    In situ detection of protein coronas is usually performed via optical methods, but light scattering may hamper these measurements. Here, the authors use diffusion NMR techniques to characterize protein corona formation on 19F-labeled nanoparticles in blood and other complex media.

    Graphene holds promise as a protective coating; however, lattice defects may hinder its practical applicability. Here, the authors investigate the oxidation behavior of graphene-coated copper foils and unveil the interplay between structural defects and oxygen radicals from water molecules in ambient air.
