Static solid-state 13 C NMR spectra of 13 CO-intercalated C60 have been measured in the range between room temperature and 4 K. In the high-temperature range, i.e., between room temperature and 100 K, the CO molecules in the "octahedral" sites of the C 60 lattice reorient rapidly on ...
We investigate the diffusion and the drift motion of λ DNA molecules near solid-state nanopores prior to their translocation through the nanopores using fluorescence microscopy. The radial dependence of the electric field near a nanopore generated by an applied voltage in ionic solution can be estima...
Cycloalkanes with 12 to 96 methylene groups show solid-solid transitions of high cooperativity. Although the molecules are highly flexible and do not contain mesogenic units as it is typical for liquid crystals, they form a mesomorphic phase. In this mesomorphic state, fast molecular motion with ...
According to quantum mechanics, the motion of the particles never ceases completely. Even at absolute zero there must remain some vibrational motion of the atoms within molecules, or vibrations of the atoms about the crystal lattice points in a solid. This motion, called zero-point vibrations, ...
The movement of a liquid along the surface of a solid caused by the greater attraction of the liquid's molecules to the surface of the solid than to each other. The liquid's molecules adhere to the solid surface and also to each other, so that each molecule pulls the next one along. ...
To coordinate cellular physiology, eukaryotic cells rely on the rapid exchange of molecules at specialized organelle–organelle contact sites1,2. Endoplasmic reticulum–mitochondrial contact sites (ERMCSs) are particularly vital communication hubs, playi
8, 9, 10, 11, 12, 13 As is well known, molecules are bound by strong intermolecular forces in solid state; that is, they are in a relatively “stationary” state and cannot move as freely as in solution. Accordingly, much research and development of molecular machines remains at the ...
The theory has been worked out explicitly for the example of two-site exchange in an I = 1 spin system that applies, e.g., to 1H or 2D NMR of water molecules flipping by 180° about the twofold axis. Large differences are found in the region where the time between the two 90° ...
The atomic-resolution images at the terrace of KBr(c)/NaCl(c) surface covered with water have been observed using an atomic-force microscope. The direct observation of the vertical motion of cations as well as the water-molecules ordered array at the interface was for the first time demonstrat...
