De et al. 1 focus their study on cells that can be approximated to first order as contractile force dipoles in which the cell axis z is oriented at an angle θ with respect to the direction of an ...

These electric dipoles are simply semiconductor nanoparticles, such as wurtzite CdS and CdSe or similar materials that are pyro- and piezoelectric. Some ferroelectric nanoparticles may also be ...

A new approach to materials engineering promises to overcome the limitation of capacitors commonly used in smartphones, displays and electric vehicles, according to a study published in Nature ...
