A Bio‐Based Chiroptical Overcrowded Alkene From Flavanone: Photoreactivity and Theoretical Investigation

Chemistry – A European Journal, Volume 32, Issue 34, 11 September 2026.
A sustainable route to photoresponsive molecular systems is achieved using the bio‐based flavanone (‐)‐isolonchocarpin from Tephrosia vogelii. Through McMurry homocoupling and light‐driven 6‐π‐electrocyclization, an overcrowded alkene and a fluorescent O‐heterocyclic phenanthrene are synthesized.

Ultrafast Optical Hydrogen Modulator in a Palladium Hydride Nanoparticulate Thin Film

Nanophotonics, Volume 15, Issue 17, 11 September 2026.
An all‐optical palladium metal‐hydride modulator was investigated with ultrashort laser pulses, which can manipulate hydrogen positions on the femto‐to picosecond timescale. The incident photons activate interstitial hydrogen atoms and their subsequent trajectories affect the dielectric properties of the palladium hydride thin film, providing optical ...

Surfactants as a Tool for Coupling Light Into Hydrodynamic Flow: The Influence of Surfactant Hydrophobicity and Head Polarity

Advanced Materials Interfaces, Volume 13, Issue 17, 8 September 2026.
Reversible light‐induced gradients at solid–liquid interfaces enable controllable interfacial transport via light‐driven diffusioosmosis. We demonstrate directed particle manipulation based on dynamically generated concentration gradients. The mechanism is broadly applicable to cationic, anionic, and non‐ionic surfactants with varying hydrophobicity ...

In‐Process Magnetization for 3D Printing of Magnetorheological Elastomer with Heterogeneous Magnetic Profile for Anisotropic Actuation

Advanced Science, Volume 13, Issue 50, 7 September 2026.
Fully programmable, in‐process 3D magnetization integrated with multi‐material printing enables soft magnetic systems with precise actuation and sensing. Discrete and continuous magnetization profiles drive bending, morphing, and locomotion, demonstrated through strain‐sensing elements, dragonfly‐inspired wings, octopus‐like tentacles, and a serpentine
