Phys.org  February 4, 2022 To overcome a longstanding problem of molecular impurities in nanoscience a team of researchers in the US (MIT, UC Berkeley, Argonne National Laboratory) developed a new technique that coaxes diverse blends of polymers and nanoparticles into spontaneously forming tiny, nested rings within minutes of adding an impurity. They hypothesized that diversifying the blend’s composition can overcome these limitations. Increasing the number of components increases mixing entropy, leading to the dispersion of different components and, as a result, enhances interphase miscibility. The molecular migration would unlock the system’s entropy that helps to distribute the material’s building blocks, […]
