Although the above algorithm—using an improved representation of neighborhoods and various original combinatorial tests/procedures—is efficient in mapping simple reactions, it fails, for instance, when the number of disconnected bonds is not minimal or when there are multiple different solutions with th...
As stated in [25], the experimental errors in the determination of the atomic Cartesian coordinates by X-Ray Crystallography or NMR may range from 0.01 to 1.27Å which is close to the value of some covalent bonds. In this work, we pursue two objectives: firstly, we propose a Variable ...
Hydrogenation of unsaturated bonds is dominated by transition metal catalysis. Compared with transition metals, the use of other metals is less explored, especially so for the s-block elements despite their ready availability and low cost. Here

The protein produces friction on the reaction coordinate as it is pulled, because not only are residues moving one against another but also bonds are being stretched. These effects slow motion over the barrier and so the rate of approaching the barrier may become rate-limiting in the sense of...

The compositions of the mixed-metal complexes were fixed by the results of inductively coupled plasma atomic emission spectroscopy (ICPAES). The [Zn1/3Fe2/3(L)] complex contained 4.63 mmol/g of zinc and 6.90 mmol/g of iron. The molar ratio of Zn to Fe was 0.62. Similarly, the...
