Janus Photonic Graphics by Stratified Assembly of Two Distinct Colloids
Advanced Functional Materials, EarlyView.Double‐sided Janus photonic micropatterns with vivid structural colors are fabricated through a single‐step bottom‐up strategy. Density‐driven stratification and depletion‐mediated crystallization of PMMA and PS binary colloids lead to exclusive lattices on opposite surfaces under centrifugal force.

Vortex interaction with a leading-edge of finite thickness
, 1987 Vortex interaction with a thick elliptical leading-edge at zero relative offset produces a pronounced secondary vortes of opposite sense that travels with the same phase speed as the primaty vortex along the lower surface of the edge. The edge thickness (

Engineering of Glioblastoma‐Derived Biomimetic Vesicles and Their Structural and Molecular Features
Advanced Healthcare Materials, EarlyView.ABSTRACT Biomimetic nanosystems and vesicles have arisen as a novel approach to design vesicular transport systems with diverse therapeutic potential. The ‘biomimetic’ strategy involves the integration of cell membrane components into lipid bilayers, conferring them with biological properties originating from the cell of origin. Until now, most studies
