CHEMISTRY: All in the Dope

Chemistry embraced by all.

C hemistry is the great enabler. For two centuries, it has played a key role in conquering diseases, solving energy problems, addressing environmental challenges, and providing discoveries that have spawned new industries. To meet the demands of the future, this mature science must expand into new frontiers, a move that will be facilitated if the public and policy-makers understand its pivotal ...

Dope: the enemy of the racehorse.

Would they dope? Revisiting the Goldman dilemma.

BACKGROUND/AIM Discussions of doping often report Goldman's sensational results that half of the elite athletes asked would take a drug that guaranteed sporting success which would also result in their death in 5 years' time. There has never been any effort to assess the properties of the 'Goldman dilemma' or replicate the results in the post World Anti-Doping Agency context. This research eval...

Does water dope carbon nanotubes?

We calculate the long-range perturbation to the electronic charge density of carbon nanotubes (CNTs) as a result of the physisorption of a water molecule. We find that the dominant effect is a charge redistribution in the CNT due to polarisation caused by the dipole moment of the water molecule. The charge redistribution is found to occur over a length-scale greater than 30 Å, highlighting the ...

Anti-dope testing in sport: the history and the science.

This summer, as the XXX modern Olympic Games and the XIV Summer Paralympic Games were held in London, millions watched magnificent efforts from the best athletes in the world. The ability of the athletes to produce their best personal performances in the spotlight and the pressure of the Olympic Games was a testament to the human spirit.
