Thickness‐Dependent Infrared Emissivity of Ultrathin Freestanding MoSiN Nanocomposite Membranes
Advanced Optical Materials, EarlyView.ABSTRACT Metals and dielectrics show opposite trends in thickness‐dependent infrared emissivity: metallic films exhibit a rise in emissivity below a critical thickness, while dielectric films show a corresponding decline. For applications demanding both high emissivity and mechanical strength in membranes with nanoscale thickness, combining these ...

On‐Chip Saturated Absorption of CO2 in a Silicon‐on‐Sapphire Waveguide
Advanced Optical Materials, EarlyView.We demonstrate the first saturated absorption of a molecular gas on a planar photonic chip. By coupling carbon dioxide with the tightly confined light of a silicon‐on‐sapphire waveguide, we achieve optical saturation using only milliwatt powers. This breakthrough provides a practical, low‐power foundation for creating ultra‐compact mid‐infrared ...

Measuring the Welfare Impact of Asymmetric Price Transmission
Measuring the Welfare Impact of Asymmetric Price TransmissionSeveral previous studies report that prices are asymmetrically transmitted across levels in US commodity markets, but the evidence about the economic magnitude of the phenomenon is limited. In this paper, we use estimated asymmetric error correction models (ECM) for producer, wholesale, and retail pork and beef prices to compute the compensating ...

Advanced Optical Materials, EarlyView.A theoretical model is developed to visualize three‐dimensional refractive index profiles in transmission holographic gratings. In this work, it is applied to photopolymerizable hydrogels, enabling detailed analysis of the internal structure of recorded holograms and their evolution under different degradation conditions.
