Norbornene Homopolymerization Limits Cell Spreading in Thiol–Ene Photoclick Hydrogels

Advanced Healthcare Materials, Volume 14, Issue 32, December 19, 2025.
Thiol–norbornene click reactions are often used in the development of cell‐permissive 3D hydrogels. However, ene–ene crosslinks in other thiol–ene systems are known to limit permissivity. This study demonstrates the negative effects of norbornene homopolymerization on 3D cell spreading and circumvents the issue by modulating polymer degree of ...

Solving the Mystery of the Electron Radiation Belt at Uranus: Leveraging Knowledge of Earth's Radiation Belts in a Re‐Examination of Voyager 2 Observations

Geophysical Research Letters, Volume 52, Issue 22, 28 November 2025.
Abstract Voyager 2 provided the only direct measurement of the radiation environment at Uranus and established the well‐accepted characterization of a system with a weaker ion radiation belt and surprisingly intense electron radiation belt. Recent re‐analysis of the flyby, however, suggests that these observations were not taken during normal solar ...

Cationic Fluorinated Polyphosphazenes for Efficient Decontamination of Anionic Pollutants from Wastewater

Macromolecular Chemistry and Physics, Volume 226, Issue 15, August 4, 2025.
This work presents a convenient synthesis of cationic fluorinated copolyphosphazenes via the quaternization of 3‐(diethylamino)phenolate (3DEAP) side groups with methyl iodide. The resulting water‐soluble copolymers, featuring tunable hydrophobic (CF3) and hydrophilic ammonium moieties, self‐assemble into large compound micelles (LCMs) or vesicles in ...

Temperature drift suppression for micro‐electro‐mechanical system gyroscope based on vibrational‐displacement control with harmonic amplitude ratio

Micro & Nano Letters
Micro‐electro‐mechanical system gyroscope detection output is susceptible to drift due to ambient temperature variations. Furthermore, the drive‐mode vibration amplitude is affected by the signal pickup circuit and structural parameters, which ...

Multiscale Fabrication and Characterization of a NEMS Force Sensor

Advanced Materials Technologies, Volume 10, Issue 4, February 19, 2025.
Fabricated silicon nanowires integrated with MEMS shuttle on a silicon‐on‐insulator wafer using novel fabrication technology enable the device to detect subtle multi‐axis forces. Gage factor tests show static manipulation response, while dynamic analysis indicates robustness and high resonant frequency.

Dynamic Analysis of a Bolted Joint Dual‐Rotor System With an Unbalanced Offset Disk Included in the Low‐Pressure Rotor

Shock and Vibration, Volume 2025, Issue 1, 2025.
The dual‐rotor structure was usually adopted in aeroengine for the sake of higher efficiency, where the high‐pressure (HP) rotor and the low‐pressure (LP) rotor are coupled together through an intershaft bearing. For the convenience of manufacturing and maintenance, the bolt connections are widely adopted in high‐power rotors to fasten together ...

Research on Chaotic Threshold of Giant Magnetostrictive Actuator With Fractional‐Order Time‐Delay Feedback

Shock and Vibration, Volume 2025, Issue 1, 2025.
To reduce the giant magnetostrictive actuator’s (GMA) irregular vibration caused by system parameter changes, we innovatively apply fractional‐order time‐delay feedback to control bifurcation and chaos in the GMA’s nonlinear dynamics. The GMA dynamic equation with feedback control is established using the quadratic domain rotation model, the Jiles ...
