Researchers from The University of Osaka fabricated a nanopore surrounded by a gate as a cooling system with enhanced efficiency for semiconductor chips. Applying a voltage to the gate induces the flow of ions through the nanopore. Creating a salt gradient makes the ion flow unidirectional. Heat is dragged along with the ions, resulting in heat transfer. Changing the applied voltage from negative to positive switches the system from cooling to heating.

A joint team has uncovered how soft, deformable particles, like cells, behave in microfluidic channels. Using precisely fabricated hydrogel particles and simulations on the supercomputer "Fugaku," they demonstrated that particle softness dramatically alters their focusing patterns, deviating significantly from rigid particle behavior. These findings reveal distinct "phase transitions" in focusing, shifting from mid-edge to eight-point, diagonal-edge, and finally center focusing as deformability increases. This breakthrough, explained by a new theoretical model incorporating inertia and deformability, offers crucial insights for designing next-generation microfluidic devices for highly efficient cell sorting and other biomedical applications like early cancer detection. The ability to control particle focusing based on deformability opens exciting possibilities for advanced particle manipulation and separation technologies.
