``On''/``off'' fluorescence intermittency of single semiconductor quantum dots
Single molecule confocal microscopy is used to investigate the detailed kinetics of fluorescence intermittency in colloidal II–VI (CdSe) semiconductor quantum dots. Two distinct modes of behavior areExpand
Nonexponential “blinking” kinetics of single CdSe quantum dots: A universal power law behavior
Single molecule confocal microscopy is used to study fluorescence intermittency of individual ZnS overcoated CdSe quantum dots (QDs) excited at 488 nm. The confocal apparatus permits the distributionExpand
Definition of the hydrogen bond (IUPAC Recommendations 2011)
A novel definition for the hydrogen bond is recommended here. It takes into account the theoretical and experimental knowledge acquired over the past century. This definition insists on someExpand
Vibrational Energy Flow in Highly Excited Molecules: Role of Intramolecular Vibrational Redistribution
A pedagogical overview of intramolecular vibrational redistribution (IVR) phenomena in vibrationally excited molecules is presented. In the interest of focus and simplicity, the topics covered dealExpand
Modeling distributed kinetics in isolated semiconductor quantum dots
A detailed modeling of recently observed nonexponential fluorescence intermittency in colloidal semiconductor quantum dots (QDs) is presented. In particular, experiments have shown that bothExpand
Single-molecule kinetics reveal cation-promoted DNA duplex formation through ordering of single-stranded helices.
TLDR
Temperature-dependent measurements reveal that increased [NaCl] reduces the overall exothermicity of duplex formation, albeit by an amount smaller than the reduction in entropic penalty (-TΔΔS° < 0). Expand
Defining the hydrogen bond: An account (IUPAC Technical Report)
The term “hydrogen bond” has been used in the literature for nearly a century now. While its importance has been realized by physicists, chemists, biologists, and material scientists, there has beenExpand
Molecular-crowding effects on single-molecule RNA folding/unfolding thermodynamics and kinetics
TLDR
First results on the single-molecule kinetics of solute molecular crowding are presented, specifically focusing on GAAA tetraloop–receptor folding to isolate a single RNA tertiary interaction using time-correlated single-photon counting and confocal single- molecule FRET microscopy. Expand
An RNA folding motif: GNRA tetraloop–receptor interactions
TLDR
This review identifies and compares types of GNRA tetraloop–receptor interactions, and explores the abundance of structural, kinetic, and thermodynamic information on the frequently occurring and most widely studied GAAA tetraloops–11 nt receptor motif. Expand
Dynamics of CO2 scattering off a perfluorinated self-assembled monolayer. Influence of the incident collision energy, mass effects, and use of different surface models.
TLDR
Rotational distributions of the scattered CO2 molecules are in agreement with experimental distributions determined for collisions of CO2 with liquid surfaces of perfluoropolyether, and the UA surface leads to an enhancement of the energy transfer efficiency in comparison with the EA surface.
