Bio‐Derived Nanophotonic Hybrids Enabling Reconfigurable Upconversion for Multilevel Optical Encryption

open access: yesLaser &Photonics Reviews, EarlyView.
A dual‐gated nanophotonic platform integrates lanthanide‐doped upconversion nanoparticles with a stimuli‐responsive silk–zirconia photonic crystal to enable multilevel optical encryption. Resonant photonic coupling allows hydration‐dependent modulation of visible emission under near‐infrared excitation, achieving reversible switching between decoy and ...

Development of Calcium‐Based Coatings to Mitigate Vanadate Corrosion

open access: yesMaterials and Corrosion, EarlyView.
Ca‐rich coatings can suppress the corrosive attack of molten V2O5 by forming Ca2 V2 O7 and Ca V2 O6. For this, a large Ca‐reservoir is key to mitigate corrosion at 600°C and 700°C. ABSTRACT Vanadate corrosion occurs in devices powered by heavy fuel oil, such as stationary turbines.

High‐Temperature Corrosion of Unpassivated Carbon Steel in Simulated Boiler Water: Electrochemical Thresholds and Mechanisms for Chloride and Sulphate Contamination

open access: yesMaterials and Corrosion, EarlyView.
Through a combination of in situ electrochemical corrosion rate measurements and FactSage thermochemistry modeling, chloride and sulphate ions were found to influence the corrosion of carbon steel in high‐temperature boiler water through distinct mechanisms: chloride acidifies the solution, raising iron solubility, while sulphate leaves solubility ...
