Bifunctionally Driven Organic Photonic Conversion Devices Facilitated by Minimalistic Synthesis‐Based Interfacial Energetic Alignment

Advanced Materials, EarlyView.
A benzene‐phosphonic acid self‐assembled monolayer (BPA) simultaneously optimizes hole extraction and noise suppression, enabling bifunctional organic photovoltaics–photodetectors that deliver superb indoor performance and commercial viability. BPA‐devices achieve 28.6% PCE at 1000 lx, retain 93% efficiency on large‐scaled devices, and reach 584 fW NEP

Rainbow Photonic Crystals: Self‐Assembly of Carbohydrate Bottlebrushes Block Copolymers

Advanced Materials, EarlyView.
Full‐color reflective 1D photonic crystals, capable of a tunable, responsive, and reversible color with high repeatability, are created from the self‐assembly of carbohydrate‐based brush block copolymers (BR01‐04). Abstract Tunable and responsive photonic crystal systems are the subject of great research interest owing to their ability to actively ...

Size‐Dependent Contact Angles of Microscopic Droplets on Ultra‐Smooth Silanized Surfaces Probed by Atomic Force Microscopy

Advanced Materials Interfaces, EarlyView.
Wetting is vital in many technologies, but remains hard to predict due to complex phase interactions. Young's law predicts macroscale wetting on ideal surfaces, while line tension theory is limited to nanoscale droplets. Here, using AFM, the scale gap is bridged by focusing on microscopic droplets and predicting their contact angle on real surfaces ...

Quasiconvexity in the Relatively Hyperbolic Groups

, 2011
We study different notions of quasiconvexity for a subgroup $H$ of a relatively hyperbolic group $G.$ The first result establishes equivalent conditions for $H$ to be relatively quasiconvex. As a corollary we obtain that the relative quasiconvexity is equivalent to the dynamical quasiconvexity. This answers to a question posed by D.
