Phys.org  April 27, 2021 To make a series of oscillators to work in unison with each other, a team of researchers (UMass Amherst, Boston University, Harvard University, University of Colorado) has developed a versatile platform of light-driven active particles with interaction geometries that can be reconfigured on demand, enabling the construction of oscillator and spinner networks. The platform relies on the Marangoni effect, which is a phenomenon that describes the movement of solids along the interface between two fluids driven by changes in surface tension. They used hydrogel nanocomposite disks made up of polymer gels and nanoparticles of gold, which […]
