A Novel Methodology for the Accelerated Desalination of Seawater Utilizing Up‐ and Down‐Conversion Phosphors
Published 2025-02-01“…In this case, upconversion (UC) and downconversion (DC) phosphors are attached to the evaporators and such phosphors are excited with near‐infrared (980 nm) or ultraviolet (360 nm) light. Consequently, green light is produced by DC/UC, which is absorbed by the evaporators to be heated and the seawater evaporation is induced. …”

<i>Cuphea hookeriana</i>: Phytochemical Profile and the Cosmeceutical and Dermatological Properties of Its Active Fraction from the Whole Plant
Published 2025-01-01“…Acute toxicity experiments showed that mice gavage orally with the fine active fraction had no significant animal toxicity at a dose of 2000 mg/kg, and the maximum tolerated dose (MTD) in mice was greater than 2000 mg/kg. In a model where ultraviolet light promotes the increase in melanin secretion in guinea pig skin tissues, both α-arbutin and the fine active fraction can reduce melanogenesis, and the effect of the fine active fraction is better than that of α-arbutin.…”
