Bonding.

In this paper, the bonding, relative stabilities and local ionic charges occurring in sodium chloride nanotubes are discussed. A new methodology is introduced which employs a linear relationship between nanotube cohesive energies determined via Density Functional Theory (DFT) and weighted-average Madelung Constants (MC(wa)). The slope of the linear plots reveals ionic charges and gives insights...

Halogen bonding, chalcogen bonding, pnictogen bonding, tetrel bonding: origins, current status and discussion.

The role of the closing lecture in a Faraday Discussion is to summarise the contributions made to the Discussion over the course of the meeting and in so doing capture the main themes that have arisen. This article is based upon my Closing Remarks Lecture at the 203rd Faraday Discussion meeting on Halogen Bonding in Supramolecular and Solid State Chemistry, held in Ottawa, Canada, on 10-12th Ju...

Comparison of Gold Bonding with Mercury Bonding*

Nine AuX molecules (X = H, O, S, Se, Te, F, Cl, Br, I), their isoelectronic HgX analogues, and the corresponding neutral HgX diatomics have been investigated using NESC (Normalized Elimination of the Small Component) and B3LYP theory to determine relativistic effects for bond dissociation energies (BDEs), bond lengths, dipole moments, and charge distributions. Relativistic effects are substanti...

molecules to evolve in the test tube. With the discovery of catalytic RNA, and advances in nucleic acid amplification techniques such as the polymerase chain reaction, it became possible to construct laboratory systems that allow the Darwinian evolution of functional RNA (and later DNA) molecules. This is not evolution based on natural selection, but rather directed evolution based on selection...

Intergenerational bonding.

T he increasing number of older people and decrease in the birth rate means that the future is going to be a very different place in terms of population profile than today. And our response to the future older citizen will be different too. For one thing, people of today's generation, who have lived through the post-war years, are likely to be better informed, educated and wealthier than previo...
