The authors report $^{13}\mathrm{C}$ NMR spin-lattice relaxation rates 1/${\mathit{T}}_{1}$ and Knight shifts ${\mathit{K}}_{\mathit{S}}$ in the quasi-two-dimensional organic superconductor \ensuremath{\kappa}-(ET${)}_{2}$Cu[N(CN${)}_{2}$]Br (${\mathit{T}}_{\mathit{c}}$=11.6 K), for an aligned single crystal. The norm…
We have investigated the equilibrium compositions and structures of the phases of nearly-hard-sphere binary colloids and obtained experimental phase diagrams. Aqueous dispersions of charge-stabilized polystyrene spheres were studied in the hard-sphere limit, with sphere-diameter ratios ranging from 2 to 12 and total v…

The importance of collective motions in proteins, such as hinge-bending motions or motions involving domains, has been recognized. Occurrence of such motions and their experimental and theoretical studies are reviewed. Normal-mode analysis and principal component analysis are powerful theoretical tools for studying su…

A photobleaching technique has been used to observe rotational dynamics of dilute probe molecules in supercooled o-terphenyl (OTP). The nonexponential rotational relaxation of the probe molecules is shown to be due, at least in part, to the presence of spatial heterogeneity in the host dynamics. Under appropriate phot…
