ParamNet: A Physics‐Guided Deep Learning Framework for Intelligent Self‐Inversion of Vacuum Optical Levitation Systems

Advanced Intelligent Systems, EarlyView.
A physics‐guided deep learning framework, ParamNet, is introduced for the intelligent self‐inversion of vacuum optical tweezers. By fuzing dual‐branch time–frequency features with physical dynamical constraints, it achieves high‐accuracy calibration of trap parameters from short‐window, low‐frequency trajectories, outperforming traditional methods ...

Effect of Annealing Temperature on the Structural, Morphological, and Optical Properties of CdSeTe Nanoparticles for Optoelectronic Applications

Advanced Physics Research, EarlyView.
A correlation between thermal treatment and enhanced crystalline quality, surface morphology, and optical response. As annealing temperature increases, structural refinement (evidenced by phrase transition from hexagonal to cubic), and more defined morphology (seen via SEM), and improved optical absorption and bandgap tuning (UV–vis and PL spectra) are

Spectral Response Modelling of Multilayer Graphene/Quantum Dot Heterostructures

Advanced Physics Research, EarlyView.
The spectral response of a multilayer heterostructure device with multiple layers of graphene and photosensitizers of different bandgaps (ZnO and quantum dots) is simulated and validated with experimental data. Our simulation incorporates photon absorption by the photosensitizers and charge collection by graphene, capturing the photoresponse dependence

First‐Principles Study of Structural, Mechanical, Electronic, Thermodynamical, and Optical Properties of XGaO2 (X = Rb and Cs): Unlocking Its Green Energy Potential

Advanced Physics Research, EarlyView.
This study employs density functional theory (DFT) to investigate the structural, mechanical, electronic, optical, and thermodynamic properties of RbGaO2 and CsGaO2. The calculated band structures and band‐edge positions indicate semiconducting behavior and favorable alignment for photocatalytic dye degradation and hydrogen evolution, highlighting ...
