In this work, the internuclear electron densities of a series of X-O bonds (where X = P, S, or Cl) have been calculated using quantum mechanics and compared to Lewis structures for which the formal charges have been minimized. A direct relationship was found between the internuclear ...

Synthesis and screening of a library of Lewisxdeoxyfluoro-analogues reveals differential recognition by glycan-binding partners Distinguishing between different proteins that each bind to the same type of glycan is challenging. Here, the authors demonstrate that an enzymatically synthesised library of Lewis...
This unit looks more in depth at molecular compounds to see how they are bonded together by looking at Lewis structures. These structures provide information about the types of bonds (single, double, or triple) as well as the connectivity of atoms. By knowing the Lewis structure, we can also...
Macrocycle-based hierarchically porous hydrogen-bonded organic frameworks were summarized, including the macrocycle structures, the hierarchically porous structures of the HOFs, and the applications induced by the hierarchically porous structures. Abstract ...
Structurally, the doped Ni raises the active particle disper-sion and the coordination numbers of Mo species (Mo-C and Mo-O), improves the graphitization degree to promote the electron transfer, and increases the amount of Lewis and Brønsted acid, which are respon-sible for the excellent ...
