New experimental evidence for pervasive dynamics in proteins

DOI: 10.1002/pro.4630
Abstract: There is ample computational, but only sparse experimental data suggesting that pico‐ns motions with 1 Å amplitude are pervasive in proteins in solution. Such motions, if present in reality, must deeply affect protein function and protein… read more here.

DOI: 10.1021/acs.langmuir.7b04156
Abstract: A general model for nuclear magnetic resonance (NMR) relaxation studies of fluid bilayer systems is introduced, combining a mesoscopic Brownian dynamics description of the bilayer with atomistic molecular dynamics (MD) simulations. An example is given… read more here.

DOI: 10.1021/jacs.1c01410
Abstract: Organometallic molecules based on [Dy(CpR)2]+ cations (where CpR is a substituted cyclopentadienyl anion) have emerged as clear front-runners in the search for high-temperature single-molecule magnets. Within this family of structurally similar molecules, significant variations in… read more here.

DOI: 10.1103/physreva.101.052707
Abstract: The charge relaxation of accumulated charge patches in insulating straight capillaries is investigated theoretically. The model assumes that charges accumulate only at the inner and outer insulator-vacuum interface of the capillary but not in the… read more here.

DOI: 10.1103/physrevlett.127.050401
Abstract: A general property of relaxation rates in open quantum systems is discussed. We find an interesting constraint for relaxation rates that universally holds in fairly large classes of quantum dynamics, e.g., weak coupling regimes, as… read more here.
