Precise characterization of nanometer-scale systems using interferometric scattering microscopy and Bayesian analysis

Kavli Affiliate: Vinothan N. Manoharan | First 5 Authors: Xander M. de Wit, Amelia W. Paine, Caroline Martin, Aaron M. Goldfain, Rees F. Garmann | Summary: Interferometric scattering microscopy (iSCAT) can image the dynamics of nanometer-scale systems. The typical approach to analyzing interferometric images involves intensive processing, which discards data and limits the precision of […]

Zonal flows and reversals of cortically confined active suspensions

Kavli Affiliate: L. Mahadevan | First 5 Authors: J. S. Yodh, F. Giardina, S. Gokhale, L. Mahadevan, | Summary: At sufficiently high concentrations, motile bacteria suspended in fluids exhibit a range of ordered and disordered collective motions. Here we explore the combined effects of confinement, periodicity and curvature induced by the active motion of E. […]

The effect of scatter of polymer chain length on strength

Kavli Affiliate: Zhigang Suo | First 5 Authors: Manyuan Tao, Shawn Lavoie, Zhigang Suo, Maria K. Cameron, | Summary: A polymer network fractures by breaking covalent bonds, but the experimentally measured strength of the polymer network is orders of magnitude lower than the strength of covalent bonds. We investigate the effect of statistical variation of […]

Non-planar snake gaits: from Stigmatic-starts to Sidewinding

Kavli Affiliate: L. Mahadevan | First 5 Authors: N. Charles, R. Chelakkot, M. Gazzola, B. Young, L. Mahadevan | Summary: Of the vast variety of animal gaits, one of the most striking is the non-planar undulating motion of a sidewinder. But non-planar gaits are not limited to sidewinders. Here we report a new non-planar mode […]

Anomalous crystalline ordering of particles in a viscoelastic fluid under high shear

Kavli Affiliate: David A. Weitz | Authors: Sijie Sun, Nan Xue, Stefano Aime, Hyoungsoo Kim, Jizhou Tang, Gareth H. McKinley, Howard A. Stone, David A. Weitz | Summary: Addition of particles to a viscoelastic suspension dramatically alters the properties of the mixture, particularly when it is sheared or otherwise processed. Shear-induced stretching of the polymers […]
