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 ...

XII-Biotech-B-Racehorse Dope Testing-1 RACEHORSE AND GREYHOUND "DOPE" TESTING

Step 1 Extraction One of two methods can be used. In solid phase extraction the sample is put on a plate coated with a substance that organic compounds (such as drugs) do not adhere to, but to which other compounds in the sample do, and then the organics washed off with a suitable solvent. In liquid-liquid extraction an organic solvent is mixed with the sample, the organic compounds migrate to ...

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...
