Combining extensional rheology with in-situ synchrotron ultrafast x-ray scattering, we studied flow-induced phase behaviors of polyethylene (PE) in a wide temperature range up to 240 °C.

Current sheets are ubiquitous plasma structures that play the crucial role of being energy sources for various magnetic phenomena. Although a plethora of current sheet equilibrium solutions have been ...

New uncertainty: A relationship between time and dissipation rate has been established in the laboratory. (Courtesy: iStock Greyfebruary) A “speed limit” on changes in non-equilibrium systems that was ...
