Large‐Area Flat Optics Color Routing in Tilted Arrays of 2D Semiconductor Nanostripes

Advanced Optical Materials, EarlyView.
We develop a scalable flat optics platform exploiting self‐organised ion‐beam sputtering and maskless glancing‐angle deposition to fabricate centimetre‐scale arrays of tilted MoS2 nanostripes. The engineered geometry activates Rayleigh anomalies, guided modes, and Mie resonances, enabling highly directional color routing and enhanced light harvesting ...

Coherent Absorption Reveals Colors Hidden in a Grey Fabry–Pérot Cavity

Advanced Optical Materials, EarlyView.
A dielectric thin film shows colors depending on its thickness; this effect can be used to encode information normally accessible through single‐beam spectroscopy. We developed a method to conceal this kind of information, based on coating the dielectric with a matched conductor, that suppresses the color‐bearing thin‐film resonances.

Spectral Reconstruction Using Broadband Inkjet‐Printed Optical Filters

Advanced Optical Materials, EarlyView.
A proof‐of‐concept for a reconstructive spectrometer based on inkjet‐printed interferometric optical filters is demonstrated. Through adaptive encoding and robust post‐processing algorithms, spectral reconstruction is achieved over a 400 nm visible bandwidth at a fraction of the cost and complexity of typical encoders while maintaining high optical ...

Thermohaline variability of AAIW in the Atlantic sector of the Southern Ocean investigated using an Altimetry Gravest Empirical Mode [PDF]

, 2013
The southeast Atlantic sector of the Southern Ocean connects the Atlantic with the Indian Ocean and the Antarctic Circumpolar Current, thereby acting as a major conduit within global ocean circulation.

Photoactive and Ultrastable Silicon/Boron Doped Diamond Photoanodes Enable Longstanding Photoinduced Electrochemiluminescence

Advanced Optical Materials, EarlyView.
This study introduces a highly durable n‐Si/BDD photoanode for photoinduced electrochemiluminescence that entirely circumvents conventional interfacial passivation. By delivering a stable photovoltage under near‐infrared irradiation, the heterojunction facilitates low‐potential optical upconversion.

Ocean Circulation to Blame for Red Tide Outbreak in the Persian Gulf and the Sea of Oman

International Journal of Maritime Technology, 2020
Red tide is a phenomenon that occurs by rapid growth or proliferation of toxic algae. The growth and spread of this phenomenon can threaten marine ecosystems, human health, aquaculture, water desalination plans, tourism and fisheries industries.

Enhancing Amphibious Flipper‐Based Locomotion Through Terrain‐Dependent Bayesian Optimization of Central Pattern Generator Control

Advanced Robotics Research, EarlyView.
A sea turtle‐inspired amphibious robot uses simulation‐guided optimization to adapt its flipper coordination to different environments. Sensitivity analysis and multiobjective Bayesian optimization identify terrain‐dependent controllers that are validated on hardware.
