Advanced Materials Interfaces, EarlyView.Zero‐dimensional carbon nanomaterials are presented as multifunctional platforms linking structure, property, and sensing performance. Surface engineering and heteroatom doping modulate electron‐transfer and luminescent behavior, enabling electrochemical, photoluminescent, and electrochemiluminescent detection. Fundamental design principles, analytical

3D Printed Multimaterial Microfluidic Transistors
Advanced Materials Technologies, EarlyView.We introduce a biocompatible, high resolution photopolymer resin that closely mimics the Young's Modulus (elasticity) and reversible stretchability (no hysteresis) of poly(dimethylsiloxane) (PDMS), enabling the fabrication of microfluidic transistors (i.e., microvalves capable of proportional amplification) by multimaterial stereolithography (mSLA ...

Advanced Optical Materials, EarlyView.Whispering‐gallery‐mode microresonators with sharp resonant peaks enable photonic barcoding. Similar to a chameleon, a rare‐earth‐free microcavity with π‐conjugated PAHs enables visibleto‐near infrared color generation from a single microbead. The unique resonat emission (spectral barcode) can be dynamically transformed via excitation wavelength change,

Evaluation of RSRM case hardware fretting concerns [PDF]
Fretting corrosion was first noted on Shuttle flight STS-26. This flight was the first usage of the Redesigned Solid Rocket Motor (RSRM). The occurrence of fretting has since been observed on both the field and factory joints of the RSRM.

Intramolecular FRET Cascades Enable Small Efficiency Roll‐Off in Solution‐Processed OLEDs
Advanced Optical Materials, EarlyView.This work highlights how an intramolecular FRET design strategy in solution‐processable MR‐TADF emitters enables narrowband emission, high PLQY, and efficient exciton harvesting. The resulting hyperfluorescent solution‐processed OLEDs reach up to 20.7% EQEmax with minimal efficiency roll‐off even at 10 000 cd m−2, demonstrating strong potential for ...
