Synthesis and Optical Properties of Single‐Crystalline Phosphors Gd3In2Ga3O12:RE3+ (RE = Nd3+ and Ho3+) Grown via the Optical Float Zone Method

Advanced Photonics Research, EarlyView.
Nd3+‐ and Ho3+‐doped Gd3In2Ga3O12 single crystals have been successfully synthesized via the optical float zone method. Their structure and optical characterization demonstrate efficient narrow‐line 4f–4f emission, low cross‐relaxation, and bright photoluminescence, indicating their potential as advanced optical materials for photonic applications.

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

Advanced 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 ...

Dual Lewis Acid Promoted/Visible Light Driven Preparation of Aryl Diazenyl Oxazoles from Isocyanoacetamides and Arylazo Sulfones

Advanced Synthesis &Catalysis, Volume 367, Issue 5, March 4, 2025.
Abstract While arylazo sulfones have been widely applied as arylating agents, their exploitation for diazenylation reactions has been previously limited to electron‐rich alkenes such as styrenes and silyl enol ethers. Herein we optimized a synthetic one‐pot protocol to access oxazolyl azo compounds via a selective domino ring‐closing/aryldiazenylation ...
