Ultrasensitive and Reliable Diamond MEMS Magnetic Force Sensor with 3D Imaging at Room Temperature

open access: yesAdvanced Materials Technologies, EarlyView.
A magnetic force sensor by integrating a single‐crystal diamond MEMS resonator with a magnetic particle, achieving exceptional sensitivity, stability, and reliability at room temperature is demonstrated. This simple yet robust design enables precise detection of magnetic field gradients and supports 3D magnetic force imaging, paving the way for next ...

The Impact of Donor‐Orientation on the Emission Properties of Chlorinated Trityl Radicals

open access: yesAdvanced Optical Materials, EarlyView.
Chlorinated trityl radicals with electron‐donating groups enable efficient red emission for optoelectronics. Donor orientation and steric constraints regulate vibronic coupling, influencing luminescence. A novel trityl derivative with restricted donor alignment minimizes non‐radiative decay, enhancing quantum yield.

Thermally Activated Delayed Fluorescence and Beyond. Photophysics and Material Design Strategies.

open access: yesAdvanced Photonics Research, EarlyView.
Photophysical properties of TADF molecules are determined by characteristic parameters that are discussed in detail(. Moreover, using femtosecond time‐resolved spectroscopy, quantum mechanical considerations, and state‐of‐art calculations, deeper understanding allows us to design breakthrough Cu(I) and organic TADF‐ OLED materials. For the latter ones,

Poka: A Necro‐Robot Beetle with a Measured Payload Ratio of 6847%

open access: yesAdvanced Robotics Research, EarlyView.
Here, Poka, a necro‐robot beetle with the ability to carry more than 68 times its own weight, is introduced, making it also a walking robot with the highest payload ratio measured to date. This paper is concerned with the design, manufacture and validation of ‘Poka', a novel millimetre‐scale necro‐robot aimed at bridging the performance gap between ...

Mg(SPh)2 as a Catalyst for Efficient Photocatalytic Alkylation Reactions of Active Methylene Compounds with Nonactivated Alkenes

open access: yesAdvanced Synthesis &Catalysis, Volume 367, Issue 5, March 4, 2025.
Abstract Mg(SPh)2 has been found to be a highly active catalyst in photocatalytic alkylation reactions of active methylene compounds with nonactivated alkenes. The desired reactions proceeded smoothly to afford the corresponding alkylated products in high yields with low catalyst loadings (0.2–0.3 mol%). This protocol is applicable to a continuous‐flow
