Digital Twin of the Photoelectric Converter of the Power Transmission System over Optical Fiber

Journal of Physics: Conference Series
Abstract The photovoltaic converter (PVC) is a key device in a power-over-fiber system (PoFS). The aim of the work is to create a digital twin (DT) to predict the behaviour of PVC based on their specification data, which is the first step towards creating a universal DT of the entire PoFS.

Optical Signature of Moiré Superlattices Formed by Twisted SrTiO3 Membranes

Advanced Functional Materials, EarlyView.
We discover optical signatures from bonded interfaces in twisted SrTiO3 moiré superlattices, including low‐frequency Raman vibrational modes and strong second‐harmonic generation, consistent with strong interlayer coupling inferred from cross‐sectional electron microscopy and ab initio calculations. ABSTRACT Moiré superlattices formed at the interfaces

Rear-heterojunction GaInP laser power converter with 59% monochromatic efficiency at 590 nm

APL Photonics
Photonic power converters (PPCs) are devices that convert narrowband light at specific wavelengths into electrical energy based on the photovoltaic effect. They are used in optical power transmission systems, which offer advantages over conventional wire

Ionic Precursors Transformed Into Vinyl Acetate Synthesis Catalyst via Reaction‐Driven Restructuring

Advanced Functional Materials, EarlyView.
This work demonstrates that a simple physical mixture of Pd and Au ionic precursors, KOAc promoter, and SiO2 support can transform into a highly active vinyl acetate synthesis catalyst through reaction‐driven restructuring. The results highlight reaction‐induced restructuring as an innovative and sustainable catalyst design strategy.
