Damping of quasi-2D internal wave attractors by rigid-wall friction
, 2017 The reflection of internal gravity waves at sloping boundaries leads to focusing or defocusing. In closed domains, focusing typically dominates and projects the wave energy onto 'wave attractors'.

Rapid Fabrication of Self‐Propelled and Steerable Magnetic Microcatheters for Precision Medicine
Advanced Materials, EarlyView.A rapid Joule heating fabrication method for the production of self‐propelling, adaptive microcatheters, with tunable stiffness and integrated microfluidic channels is presented. Demonstrated through three microrobotic designs, including a steerable guiding catheter, an untethered wave‐crawling TubeBot, and a distal‐end propelled microcatheter, it was ...

On the Normal Force and Static Friction Acting on a Rolling Ball Actuated by Internal Point Masses
, 2019 The goal of this paper is to investigate the normal and tangential forces acting at the point of contact between a horizontal surface and a rolling ball actuated by internal point masses moving in the ball's frame of reference.

Flexoelectrically Induced Polar Topology in Twisted SrTiO3 Membranes
Advanced Materials, EarlyView.Twisted SrTiO3 bilayers host polar vortices of flexoelectric origin, revealed through combined experiment and theory. By reconstructing polarization from the toroidal moment of strain gradients, the work establishes a 3D chiral state with broken inversion and mirror symmetries.

Active Brownian Particles. From Individual to Collective Stochastic Dynamics
, 2012 We review theoretical models of individual motility as well as collective dynamics and pattern formation of active particles. We focus on simple models of active dynamics with a particular emphasis on nonlinear and stochastic dynamics of such self ...

Advanced Materials, EarlyView.Triply‐twinned architected lattices transform deformation from bending to stretching of struts, delivering up to threefold increases in stiffness and strength across polymeric and metallic systems. High‐resolution synchrotron XCT and image‐based simulations reveal how meta‐grain architecture, defects, and AM build orientation govern failure pathways ...

PREDICTION OF ANGLE OF INTERNAL FRICTION OF SAND USING GRAIN-SIZE DISTRIBUTION CURVE [PDF]
JES. Journal of Engineering Sciences, 2008 The shear strength parameters play an important role in many practices for geotechnical engineering. To determine the real values of these parameters requires undisturbed samples and that is difficult for cohesionless soil. So, prediction of shear strength parameter such as angle of internal friction in the case of cohesionless soil with the help of ...
