Charge transport in electrorheological fluids is studied experimentally under strongly nonequilibrium conditions. By injecting an electrical current into a suspension of conducting nanoparticles we are able to initiate a process of self-organization which leads, in certain cases, to formation of a stable pattern which consists of continuous conducting chains of particles. The evolution of the d...

Magnetorheological (MR) fluids are field-responsive suspensions of magnetizable particles which rheological properties can be dramatically altered by applying external magnetic fields (Phulé and Ginder 1998). Under the presence of a magnetic field, anisotropic chainlike structures result from field-induced particle magnetization as a consequence of the permeability mismatch between particle and...

Smart Table Tennis Racket In article number 2100535, Mengying Zhang, Jinbo Wu, and coworkers invent a smart table tennis racket with tunable stiffness based on electrorheological elastomers. The face is multilayer structure of rubber, soft electrode, anisotropic elastomer copper electrode. By applying an electric field, the successfully changed trajectory balls, reduced ejection angle increased...
