چکیده

Chladni patterns based on nanomechanics in the microfluidic environment are presented. In contrast with the macroscopic observations in the gaseous environment, nanoparticles are found to move to the nodes, whereas micron-sized particles move to the antinodes of the vibrating interface. This opens the door to size-based sorting of particles in microfluidic systems, and to highly parallel and controlled assembly of biosensors and nanoelectronic circuits.

Chladni Figures and the Tacoma Bridge: Motivating PDE Eigenvalue Problems via Vibrating Plates

Teaching linear algebra routines for computing eigenvalues of a matrix can be well motivated to students using interesting examples. We propose in this paper to use vibrating plates for two reasons: first there are interesting applications, from which we chose the Chladni figures representing sand ornaments which form on a vibrating plate, and the Tacoma bridge, one of the most spectacular brid...

The Y9P Variant of the Titin I27 Module: Structural Determinants of Its Revisited Nanomechanics.

The titin I27 module from human cardiac titin has become a standard in protein nanomechanics. A proline-scanning study of its mechanical clamp found three mechanically hypomorphic mutants and a paradoxically hypermorphic mutant (I27Y9P). Both types of mutants have been commonly used as substrates of several protein unfoldase machineries in studies relating protein mechanostability to translocat...

Formation of inverse Chladni patterns in liquids at microscale: roles of acoustic radiation and streaming-induced drag forces

While Chladni patterns in air over vibrating plates at macroscale have been well studied, inverse Chladni patterns in water at microscale have recently been reported. The underlying physics for the focusing of microparticles on the vibrating interface, however, is still unclear. In this paper, we present a quantitative threedimensional study on the acoustophoretic motion of microparticles on a ...

Seeing and Hearing the Eigenvectors of a Fluid

The intricate shapes and sounds that arise from vibrating Chladni plates are a well-known phenomenon. They are also quantitatively well understood, as the spatial patterns correspond to the eigenvectors of the underlying plate, and the audio frequencies arise from the plate’s eigenvalues. We explore a generalization of the phenomenon by computing analogous quantities for a computational fluid d...

Manipulating Standard and Inverse Chladni Patterns by Modulating Adhesive, Frictional, and Damping Forces

Particles on a plate form Chladni patterns when the plate is acoustically excited. To better understand these patterns and their possible real-world applications, I present a new analytical and numerical study of the transition between standard and inverse Chladni patterns on an adhesive surface at any magnitude of acceleration. By spatial autocorrelation analysis, I examine the effects of surf...
