KIOST validates prototype ultrasonic desalination instrument of sea sand

KIOST has developed an ultrasonic washing device that effectively removes salt from sea sand, reducing water usage and processing time by up to four times. The technology uses cavitation-driven ultrasonic waves to desalinate sea sand, resulting in a significant improvement over traditional methods.

KIOST reveals process by which marine microalga Heterosigma akashiwo causes buoyant microplastics to sink

Marine microalgae Heterosigma akashiwo forms aggregates of buoyant microplastics through extracellular polymeric substances, increasing their density and causing them to sink. The sinking velocity of these aggregates is significant for understanding the behavior of microplastics in marine ecosystems.
