In situ SAXS/WAXS enables real‐time tracking of nanoparticle formation and evolution in exsolved and infiltrated Ni‐based perovskites under reducing conditions. The combined technique captures nucleation, growth, and coarsening dynamics with high temporal resolution, providing statistically robust insights into structural and morphological ...

Phonon Engineering in Ultrathin Sn Films
When embedded in multilayer structures, ultrathin Sn layers demonstrate strongly modified vibrational density of states (VDOS). This allows engineering a drastic increase of the Lamb‐Mössbauer factor fLM$f_{\text{LM}}$ and thereby of the cross‐section for coherent excitation of the ultrasharp nuclear resonance of 119Sn$^{119}{\rm Sn}$. This enables the

Monolithic narrow-linewidth InGaAsP semiconductor laser for coherent optical communications [PDF]
A design for a monolithic narrow-linewidth InGaAsP diode laser has been developed using a multiple-quantum-well (MQW) extended-passive-cavity distributed-Bragg-reflector (DBR) laser design.

Spin‐Crossover Confinement in Mesoporous Matrices Enables Tunable Porosity for Molecular Sensing
The integration of hierarchically organized porous frameworks with spin‐crossover nanodomains enables cooperative interactions across multiple length scales. This hybrid design merges dynamic molecular switching with tunable porosity, yielding materials whose structural and functional responses are actively modulated by confinement and guest uptake ...

ZnO/CeO2 composite nanoparticles synthesized via a facile hydrothermal method simultaneously degrade ciprofloxacin, tetracycline, methylene blue, and methyl orange in a four‐component mixture under UV irradiation. The Ce3+/Ce4+ redox cycling and oxygen vacancies at the ZnO/CeO2 interface suppress charge recombination and enhance reactive species ...

Development of Laterally Graded X‐Ray Multilayer Optics
This work presents the development of laterally graded X‐ray multilayer optics with both constant and variable lateral gradients. By precisely controlling substrate speed profiles and mask design, these multilayers achieve highly accurate lateral gradients and excellent sagittal thickness uniformity, making them ideal for spectroscopy application at ...

Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...

This study explores how machine learning models, trained on small experimental datasets obtained via Phase Doppler Anemometry (PDA), can accurately predict droplet size (D32) in ultrasonic spray coating (USSC). By capturing the influence of ink complexity (solvent, polymer, nanoparticles), power, and flow rate, the model enables precise droplet control
