True colors: Using X-rays to trace the evolution of insects' structural colors

While different families of insects grow different kinds of nanostructures, they all converge on similar lustrous qualities. These are not colors made with pigments, so they don't fade with time. The crystalline structures reflect light in such a way that the colors are iridescent, brighter and more arresting than the colors we can produce chemically.

Novel acoustofluidic technology isolates nanoparticles

Researchers developed a novel nanoacoustic trapping device that manipulates particles within submicron ranges by applying a structured elastic layer at the interface between a microfluidic channel and a travelling surface acoustic wave.

Liquid-phase fabrication method for producing nanocellulose films with multiple axes of alignment

Researchers develop liquid-phase 3D-patterning to create nanocellulose films aligned along multiple axes within the same sheet. This work may lead to ever more sophisticated optical and thermal devices or even 'paper electronics'.
