Bio‐Inspired Molecular Events in Poly(Ionic Liquids)
Advanced Functional Materials, EarlyView.Originating from dipolar and polar inter‐ and intra‐chain interactions of the building blocks, the topologies and morphologies of poly(ionic liquids) (PIL) govern their nano‐ and micro‐processibility. Modulating the interactions of cation‐anion pairs with aliphatic dipolar components enables the tunability of properties, facilitated by “bottom‐up ...

Uncovering the Origin of Efficiency Roll‐Off in TADF OLEDs
Advanced Functional Materials, EarlyView.OLEDs based on thermally activated delayed fluorescent (TADF) materials often suffer from a severe drop in efficiency at high brightness levels. This work presents a technique to uncover the source of this efficiency drop, and quantifies the exciton‐exciton and exciton‐polaron annihilation processes responsible for efficiency losses in our TADF OLEDs ...

Advanced Materials Interfaces, EarlyView.A simple strategy is presented for bonding acrylic PSAs and silicone elastomers by curing surfactant‐doped Ecoflex on oxygen‐plasma‐treated VHB. The interface reaches a maximum strength of 1.6 N/mm (over 20 times that of the control) while retaining material compliance.

TS-MUWSN: Time synchronization for mobile underwater sensor networks [PDF]
, 2016 Time synchronization is an important, yet challenging, problem in underwater sensor networks (UWSNs). This challenge can be attributed to: 1) messaging timestamping; 2) node mobility; and 3) Doppler scale effect. To mitigate these problems, we present an
