single‐molecule studiesThe cover picture shows the visualization of single poly(n-butyl acrylate) brush molecules in real time by scanning force microscopy as they transform reversibly from an extended wormlike state to a compact globular state. The reversible transformation is effected by co-...
In fact, the energy of a given molecular graph compared to the total energy of the electrons of a molecule is of interest to chemists. Obviously, the energy of a graph with all isolated vertices is zero, but for a complete graph with n vertices, it is \(2(n - 1)\). The energy ...
These quantum mechanical notions are usually oversimplified or meticulously circumvented in other books, to the frustration of serious readers who want to understand, for example, why two protons can be stably bound with only one electron to make the simplest molecule H 2 +. An initial, concise...
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...
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; ...

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...
(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...
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 ...
