Molecular structure transitions, including photo‐induced configurational changes, chemical bond rotation‐induced stereoelectronic effects and hydrogen bond or other non‐covalent interactions, can be detected directly in real time through single‐molecule electrical approaches. This helps to explore the ...
What's the difference between a model of a molecule and a picture of a molecule? A model of a molecule would be a three-dimensional representation, while a picture would be a flat, two-dimensional image. 9 Do both models and pictures serve the purpose of representation? Yes, both serve ...
real soil mineral surface, there are some limitations to DFS, but more complex systems could be imagined. In particular, a flat region (~100 nm2) would be preferred to prevent interactions from a combination of both edge and basal sites. Freshly cleaving the mineral is not necessary; ...
We have also focused on dimers involving molecules in out-of-equilibrium geometries, i.e., ethene dimer with one of the monomers twisted, ethene–fluorine complex with F–F bond stretched and compressed, and the same complex with ethene molecule twisted. Those computations were also performed in...
(18F), with radioactive half-lives of 20 and 110 min, respectively. Due to these short half-lives, PET radioligands are generated in a cyclotron and are rapidly incorporated into the molecule of interest immediately prior to their use (8). In SPECT, the commonly used isotope is technetium...

The rate of evaporation of solvent determined as an increase of the number of one-molecule water clusters through a chosen time period was evaluated for the periods 0–36 ps, 36–72 ps, and 0–72 ps of production time. Figure 23 shows the results for all 24 systems under 1.5 V/nm. ...
When plants come under attack internal alarm bells ring and their defence mechanisms swing into action - and it happens in the space of just a few minutes. Now, for the first time, plant scientists - including experts from The University of Nottingham - have imaged, in real time, what happ...
[200] found that SRT2104, a synthetic small molecule activator of SIRT1, extended both mean and maximal lifespan of mice. It is impossible to draw any firm conclusions at this point but, hypothetically, given its beneficial effects on endothelial cells and its apparent ubiquity in snake venoms...
