Resonant intermolecular transfer of vibrational energy in liquid water
Many biological, chemical and physical processes involve the transfer of energy. In the case of electronic excitations, transfer between molecules is rapid, whereas for vibrations in the condensed
Negligible Effect of Ions on the Hydrogen-Bond Structure in Liquid Water
This result shows that the presence of ions does not lead to an enhancement or a breakdown of the hydrogen-bond network in liquid water.
IM30 triggers membrane fusion in cyanobacteria and chloroplasts.
It is proposed that IM30 establishes contacts between internal membrane sites and promotes fusion to enable regulated exchange of proteins and/or lipids in cyanobacteria and chloroplasts.
Subpicosecond conformational dynamics of small peptides probed by two-dimensional vibrational spectroscopy
Complementary molecular-dynamics simulations confirm that the conformational fluctuations exhibit a subpicosecond component, the time scale and amplitude of which agree well with those derived from the experiment.
Anomalous Temperature Dependence of Vibrational Lifetimes in Water and Ice
Many physical properties of water exhibit a remarkable temperature dependence. The best known example is probably the density, which is larger in the liquid than in the solid phase. Other examples
Operation Mechanism of a Molecular Machine Revealed Using Time-Resolved Vibrational Spectroscopy
It is found that the shuttling involves two steps: thermally driven escape from the initial station, followed by rapid motion along the track ending either at the initial or final station, which approximates a biased one-dimensional random walk.
Coupling of the Amide I Modes of the Glycine Dipeptide
Several approaches to calculate the coupling between the two amide I modes of the glycine dipeptide are compared. The full (φ, ψ) conformational space of the molecule is explored, and conditions for
C-Terminal Truncated α-Synuclein Fibrils Contain Strongly Twisted β-Sheets
High-resolution microscopy and advanced vibrational spectroscopy studies indicate that the C-terminal truncation variant of αS, lacking residues 109–140 (henceforth referred to as 1–108-αS), forms amyloid fibrils with a distinct structure and morphology.
Characterization of Porphyrin-Co(III)-'Nitrene Radical' Species Relevant in Catalytic Nitrene Transfer Reactions.
To fully characterize the Co(III)-'nitrene radical' species that are proposed as intermediates in nitrene transfer reactions mediated by cobalt(II) porphyrins, different combinations of cobalt(II)
