Responsive Visible‐Wavelength Metasurfaces from Porous Silicon Based on Fano Guided‐Mode Resonance

Advanced Optical Materials, EarlyView.
The article introduces mesoporous silicon metasurfaces (pSi‐MS) supporting Fano guided‐mode resonances in the visible regime. By combining top‐down lithographic patterning of 2D gratings with bottom‐up electrochemical porosification, the approach realizes a new class of responsive metasurfaces, enabling highly sensitive and portable platforms for small

A General-applications Direct Global Matrix Algorithm for Rapid Seismo-acoustic Wavefield Computations [PDF]

A new matrix method for rapid wave propagation modeling in generalized stratified media, which has recently been applied to numerical simulations in diverse areas of underwater acoustics, solid earth seismology, and nondestructive ultrasonic scattering ...

Optical Diversity and Nanostructural Organization in the Colored Scales of Sternotomis

Advanced Optical Materials, EarlyView.
Vivid colors in Sternotomis beetles originate from nanoscale photonic architectures embedded within individual scales. Here, we provide a comparative optical and structural analysis of 57 scale types that reveal how ordered, quasi‐ordered, and disordered 3D networks tune color, saturation, and angular response.

Ocean foam generation and modeling [PDF]

A laboratory investigation was conducted to determine the physical and microwave properties of ocean foam. Special foam generators were designed and fabricated, using porous glass sheets, known as glass frits, as the principal element. The glass frit was

Coastal Tropical Convection in a Stochastic Modeling Framework

, 2017
Recent research has suggested that the overall dependence of convection near coasts on large-scale atmospheric conditions is weaker than over the open ocean or inland areas. This is due to the fact that in coastal regions convection is often supported by

Ratiometric Temperature Sensing through Alternating Current Electroluminescence

Advanced Optical Materials, EarlyView.
Thermoresponsive alternating current electroluminescence (ACEL) is realized in ZnS microparticles with optimized Cu, Cl, and Co tri‐doping concentrations, exhibiting a blue‐to‐green emission band shift along with increasing temperature. Based on this behavior, an ACEL‐driven temperature sensing platform is developed for quantitative temperature ...

Ocean Emulation With Fourier Neural Operators: Double Gyre

Journal of Advances in Modeling Earth Systems
A data‐driven emulator for the baroclinic double gyre ocean simulation is presented in this study. Traditional numerical simulations using partial differential equations (PDEs) often require substantial computational resources, hindering real‐time ...

Atmospheric potential oxygen: New observations and their implications for some atmospheric and oceanic models [PDF]

, 2006
Measurements of atmospheric O2/N2 ratios and CO2 concentrations can be combined into a tracer known as atmospheric potential oxygen (APO ≈ O2/N2 + CO2) that is conservative with respect to terrestrial biological activity.
