A fluorescent molecular tension sensor for spatially and temporally mapping the mechanical strain exerted by cell-surface receptors in living cells is described.
Toothpaste, mayonnaise and other systems are soft particle glasses. In these, the soft particles are jammed so that the glasses behave like weak solids at rest but at sufficient stress flow like liquids. This has made their theoretical understanding difficult. A new micromechanical model is now able to predict the rheology of these soft particle glasses.
Surface acoustic waves can actively modulate the optical mode of a photonic crystal defect cavity. Fast tuning rates, compared with the typical lifetimes of optical emitters and photons inside the cavity, pave the way for deeper insights into cavity quantum electrodynamics.
R. Li and L. Z. Sun Magnetorheological (MR) elastomer composites with the addition of multi-walled carbon nanotubes are developed. The dynamic mechanical responses of the MR nanocomposites to applied magnetic fields are investigated through dynamic mechanical analysis. It is found that a small amount of carbon nanotube ...

Jianwei Li and Minqiang Xu A robust magnetomechanical effect model is desirable for the measurement of magnetic properties in the evaluation of stress in ferromagnetic materials. The previous classical Jiles-Atherton-Sablik model has some limitations in describing the asymmetry in magnetic behavior under tensile and compressi ... [J. Appl. Phys.
Studying mechanical resonators via radiation pressure offers a rich avenue for the exploration of quantum mechanical behavior in a macroscopic regime. However, quantum state preparation and especially quantum state reconstruction of mechanical oscillators remains a significant challenge.
