Waveguide Photoactuators: Materials, Fabrication, and Applications

Advanced Robotics Research, EarlyView.
Waveguide photoactuators convert guided light into mechanical motion. Their tethered‐flexible design enables minimally invasive surgery and confined‐space robotics. This review aims to guide materials selection, device design, and system integration, accelerating the transition of waveguide photoactuators from laboratory prototypes to versatile ...

Oxygen‐Acceptor‐Driven High Photochromic Contrast Solid‐State Excited‐State Intramolecular Proton Transfer Photoswitches

Angewandte Chemie, EarlyView.
The excited‐state intramolecular proton transfer (ESIPT) photoswitch tpmSA, which features an oxygen−acceptor, exhibits higher photochromic contrast (ΔE*Lab>74) than its nitrogen‐acceptor Schiff base analogues (ΔE*Lab<30). Theoretical calculations indicate that tpmSA effectively suppresses GSIPT, thereby enhancing the contrast.

Liquid Crystalline Elastomers in Soft Robotics: Assessing Promise and Limitations

Advanced Robotics Research, EarlyView.
Liquid crystalline elastomers (LCEs) are programmable soft materials that undergo large, anisotropic deformation in response to external stimuli. Their molecular alignment encodes directional actuation in a monolithic structure, making them long‐standing candidates for soft robotic systems.

Energy‐Enhanced Aqueous Organic Flow Batteries Enabled by Integrated Proton‐Coupled Electron Transfer‐Induced Carbon Capture and Utilization

Advanced Energy Materials, EarlyView.
This work presents an aqueous organic flow battery that integrates energy storage with carbon capture and utilization. By feeding flue gas into an oxygen‐tolerant FFDS posolyte, reversible CO2 capture, utilization, and release is achieved via PCET‐driven pH swings.

Electron attachment to trans-azobenzene

Physical Chemistry Chemical Physics, 2009
The temporary anion states of gas-phase trans-azobenzene are characterised by means of electron transmission spectroscopy (ETS) in the 0-6 eV range. The measured energies of vertical electron attachment are compared with the energies of the pi* virtual orbitals of the neutral molecule supplied by HF (at MP2 optimized geometries) and B3LYP calculations.

Modeling the Mechanisms of the Photomechanical Response of a Nematic Liquid Crystal Elastomer

, 2011
Recent studies of azo-dye doped liquid crystal elastomers show a strong photomechanical response. We report on models that predict experimental results that suggest photothermal heating is the dominant mechanism in a planar constrained geometry.

Accelerating Primary Screening of USP8 Inhibitors from Drug Repurposing Databases with Tree‐Based Machine Learning

Advanced Intelligent Discovery, EarlyView.
This study introduces a tree‐based machine learning approach to accelerate USP8 inhibitor discovery. The best‐performing model identified 100 high‐confidence repurposable compounds, half already approved or in clinical trials, and uncovered novel scaffolds not previously studied. These findings offer a solid foundation for rapid experimental follow‐up,

Stabilizing a Molecular Switch at Solid Surfaces: A Density-Functional Theory Study of Azobenzene at Cu(111), Ag(111), and Au(111)

, 2009
We present a density-functional theory trend study addressing the binding of the trans-cis conformational switch azobenzene (C6H5-N=N-C6H5) at three coinage metal surfaces. From the reported detailed energetic, geometric, and electronic structure data we
