Application of Circular Economy Principles to Power Generation: Extending the Life of A Hydropower Plant by Pumped Hydro Energy Storage

Sustainable Development, EarlyView.
ABSTRACT The application of circular economy, which aims to maximize efficiency and reduce waste, to renewable energy sources necessitates, given the intermittent nature of the latter, robust energy storage solutions to ensure grid stability and avoid wasting energy.

A Dual‐Mode Photoconductive Colorimetric Wearable UV‐Dosimeter: Strategies for Tunable UV‐Band Sensitivity

Small, EarlyView.
The harmful ultraviolet component of sunlight necessitates reliable and wavelength‐selective personal UV monitoring technologies. Here, thermally evaporated CuBr thin films enable dual‐mode UV dosimetry through persistent photoconductive and colorimetric responses arising from charge trapping and surface oxide formation.

Additive Manufacturing of Hot‐Work Tool Steel by In Situ Alloying Using Laser Powder Bed Fusion and Directed Energy Deposition—Strategies to Improve Chemical Homogeneity

steel research international, EarlyView.
To support future alloy development a powder mixture is processed by laser additive manufacturing. The powder mixture containing Mo‐ and W‐rich tracers is processed by powder bed fusion using single and double laser exposure and by directed energy deposition which provides drastically enlarged melt pools.
