Donor‐Substituted C(sp3)‐Bridged Phosphorus‐Heterotriangulenes as Blue Thermally Activated Delayed Fluorescence Emitters

Advanced Optical Materials, EarlyView.
The newly developed regioselective strategy for the para‐functionalization of C(sp3)‐bridged phosphorus‐centered heterotriangulene delivers a series of donor‐acceptor emitters exhibiting thermally activated delayed fluorescence. The carbazole‐substituted compounds feature a unique combination of high photoluminescence quantum yields up to 75%, deep ...

Collision‐Resilient Winged Drones Enabled by Tensegrity Structures

Advanced Robotics Research, EarlyView.
Based on structures of birds such as the woodpeck, this article presents the collision‐resilient aerial robot, SWIFT. SWIFT leverages tensegrity structures in the fuselage and wings which allow it to undergo large deformations in a crash, without sustaining damage. Experiments show that SWIFT can reduce impact forces by 70% over conventional structures.

Origami‐Inspired Structural Design for Aquatic‐Terrestrial Amphibious Robots

Advanced Robotics Research, EarlyView.
This work presents a lightweight amphibious origami robot actuated by a single shape memory alloy wire. A rigid foldable origami structure with displacement amplification enables efficient terrestrial crawling and aquatic swimming. The addition of fan‐shaped units allows controllable turning in both environments.

Dihedral Angle Entropy Measures for Intrinsically Disordered Proteins [PDF]

The Journal of Physical Chemistry B, 2015
Protein stability is based on a delicate balance between energetic and entropic factors. Intrinsically disordered proteins (IDPs) interacting with a folded partner protein in the act of binding can order the IDP to form the correct functional interface by decrease in the overall free energy.

Directing the Mobility of Guest Molecules in Nanoporous Materials by Linearly Polarized Light

Advanced Science, EarlyView.
The polarization of light is introduced as a further parameter to dynamically and reversibly control the properties of a photoresponsive nanoporous material. It was used to control the mobility of the guest molecules in the pores of a metal–organic framework.
