Capillary assembly of microscale ellipsoidal, cuboidal, and spherical particles at interfaces
Micron-sized anisotropic particles with homogeneous surface properties at a fluid interface
can deform the interface due to their shape. The particles thereby create excess interfacial …

Critical structural fluctuations of proteins upon thermal unfolding challenge the Lindemann criterion
Internal subnanosecond timescale motions are key for the function of proteins, and are
coupled to the surrounding solvent environment. These fast fluctuations guide protein …
