Research question & Methodology
How does particle loading and coating thickness of 5 µm BaSO₄ formulations on metal coupons impact sub-ambient temperature drop under direct solar irradiance?
Formulation & Literature
Benchmarked against Purdue (Xiulin Ruan 2021) optical models; testing high bandgap BaSO₄ particle dispersion in acrylic matrices.
Recruitment status
Recruitment closed. Currently in internal experimental sample preparation and coupon coating phase.
Coupon testing setup
Calibrated Type-K thermocouples with shielded radiation enclosures logging ambient vs coupon surface temperatures.
