The discovery of the hydrodynamic electron liquid (HEL) in graphene [D. Bandurin \emph{et al.}, Science {\bf 351}, 1055 (2016) and J. Crossno 1058 (2016)] has marked birth solid-state HEL which can be probed near room temperature a table-top setup. Here we examine terahertz (THz) magneto-optical (MO) properties HEL. Considering case where magnetic length $l_B=\sqrt{\hbar/eB}$ is comparable to m...

A cationic and an anionic poly(N-isopropylacrylamide) (poly(NIPAM)) microgel latex were synthesized via batch radical polymerization under emulsifier-free conditions. The hydrodynamic properties, colloidal stability, and electrokinetic characteristics of these two samples were studied. The hydrodynamic particle size variation was discussed by considering the effect of salinity and temperature o...
