Strain‐Tunable Photoluminescence From Ge Quantum Dots on Si Nanotips for CMOS‐Compatible Photonics

Advanced Physics Research, EarlyView.
This work studies strain in Ge quantum dots grown on Si nanotips using photoluminescence, X‐ray diffraction, and band structure calculations. It shows how emission changes with dot size, evaluates strain in the dot and substrate, and explains the role of direct and indirect transitions in the optical behavior.

Compositionally Engineered Carboxymethyl Cellulose‐Based Optical Fibers With Exceptionally Low Optical Loss and Quantitative Humidity Sensing

Advanced Physics Research, EarlyView.
Carboxymethyl cellulose‐based biopolymer optical fibers are fabricated using aqueous wet spinning. The fibers exhibit record‐low optical attenuation in polysaccharide‐based waveguides while maintaining efficient transmission across the visible‐to‐near‐infrared region of the electromagnetic spectrum.

Ultrafast RF Spectrum Analyzer Assisted by Optical Short‐Time Fourier Transform

Advanced Physics Research, EarlyView.
We present Recent efforts in an ultrafast RF spectrum analyzer based on the short‐time Fourier transform (STFT) at over 10 MHz frame rate and over 40GHz bandwidth to improve performance and support applications. All these efforts could inspire more innovative applications of temporal imaging modalities in the future.

Metal nanostructure‐coupled label‐free localized surface plasmon resonance biosensors for rapid and sensitive disease diagnosis

BMEMat, EarlyView.
LSPR biosensing enables rapid, sensitive, and low‐sample‐volume detection of biomarkers, with broad applications in diagnosing cancer, infectious, and chronic diseases. Advances in nanostructure design, micro/nanofabrication, and microfluidic integration have expanded the potential of LSPR sensors in biomedical diagnostics.

Upcycling Real‐World Post‐Consumer Polyolefins Plastics Into Light Olefins Via Microwave‐Assisted Processing

Carbon Energy, EarlyView.
Microwave‐driven Ru@α‐Fe2O3 selectively upgrades real‐world post‐consumer mixed polyolefin waste into light olefins with high gas yields and olefin selectivity at markedly reduced temperatures compared with conventional thermal pyrolysis. Strong tolerance of additives and feed heterogeneity highlights an energy‐efficient and scalable route for circular
