have exhibited potential applications in various energy-conversion reactions1,2,3,4,5,6. Apart from their maximized atomic utilization, SACs are famous for their uniform active sites which benefit the selectivity and offer an ideal platform for mechanistic investigation7,8,9,10. However, the...
Secondly some results on molecules are discussed in terms of information obtainable on the dynamics of the electronic structure. Finally the application of the technique to solids is considered on the basis of both preliminary data from experiments carried out on thin films and theoretical ...
About 3.29 x 1016time units after our home planet’s formation, a series of exceedingly improbable chance events conspired to effect the formation of a class of self-replicating molecules. These replicators we consider our earliest molecular mothers. They comprise cyclical units made of the 1st, 6...

we reveal that both the bump amplitude andtThscaling are more sensitive to the atom number than the lattice size. This strong dependence on the atom number is not affected by the atomic hyperfine structure, e.g., single- or two-states; the symmetry class, and the choice of driving protocol...
We have calculated the differences between kinetic, nuclear attraction, and two-electron energies as well as the position intracules, P(u), for 56 molecules and 17 atoms contained in the G1 test set, using basis sets differing in their degree of polarization. The calculations were performed ...
Last but not least, and occurring even in the extremely high vacuum of cryogenic EBITs (some 10−11 mbar), there are collisions with neutral atoms or molecules of the residual gas. In the quest for long storage times, the charge exchange (CX)—electron transfer from the neutral gas ...

Table 1. Properties of AX diatomic molecules (X = F, Cl and Br). VS(X) is computed maximum or minimum of VS(r) on X, on the extension of the A–X bond. The minima are explicitly indicated. χA − χX is difference in electronegativities of A and X. R1 and R2 are distances...
