Effect of charging of phase change material in vertical and horizontal rectangular enclosures in a concentrated solar receiver

Case Studies in Thermal Engineering, 2020
The charging of phase change material (PCM) in a concentrated solar receiver is experimentally carried out in a parabolic dish collector. Rectangular PCM filled enclosures of 30 mm width in the solar receiver are investigated to study the effect of ...

Thermodynamic Analysis of a Conceptual Fixed-Bed Solar Thermochemical Cavity Receiver–Reactor Array for Water Splitting Via Ceria Redox Cycling

Frontiers in Energy Research, 2021
We propose a novel solar thermochemical receiver–reactor array concept for hydrogen production via ceria redox cycling. The receiver–reactor array can improve the solar-to-fuel efficiency by realizing the heat recuperation, reduction, and oxidation ...

3D-Printed Solar Cavity Receiver for Heating Pressurized Air – A Preliminary Evaluation

SolarPACES Conference Proceedings
High-temperature solar receivers experience non-uniform solar flux, which induces thermal stress in the receiver tubes. This stress is more pronounced in gas solar receivers due to the lower thermal conductivity of gases.

Composites of Shellac and Silver Nanowires as Flexible, Biobased, and Corrosion‐Resistant Transparent Conductive Electrodes

Advanced Functional Materials, EarlyView.
Shellac, a centuries‐old natural resin, is reimagined as a green material for flexible electronics. When combined with silver nanowires, shellac films deliver transparency, conductivity, and stability against humidity. These results position shellac as a sustainable alternative to synthetic polymers for transparent conductors in next‐generation ...
