"Chemistryon thenanometer scaleoften appears to be different compared to chemistry in the normal scale and carbon nanotubes provide ideal conditions for studies of reactions in nanospace," says Alexandr Talyzin, docent at the Department of Physics, Umeå University. The standard approch to make che...

In alkaline solution, rapid changes occur initially at all wavelengths, but the final ferrocytochrome c absorption spectrum only appears with a half-life of about a tenth of a second at room temperature. The activation energy for this reaction is 20 Kcal per mole. In alkaline solution the ...
One mole of propionic acid ( I ) reacts with 2 mol of 1,2‐butylene oxide ( II ) in the presence of lithium naphthalenide to give 4‐hydroxy‐2‐(2′‐hydroxybutyl)‐2‐methylhexanoic acid ( V ), which can be easily converted into 2‐(2′‐hydroxybutyl)‐2‐methyl‐4‐ethyl‐γ‐...
One mole of coloroacetone is gradually added and the solution boiled in a reflux condenser for 2 hours. On cooling the potassium chloride precipitate is separated off by filtration. The residue is distilled to give 2-acetyl-1-benzofurane, BP: 135°C/15 mm Hg. 2. It was reduced by ...

These interactions provided a docking score of −4.4 kcal/mole (Figure 5B). Derivative 1 participated in two interactions (Figure 5C). The 4-hydroxyl of the β-phenyl ring in 1 hydrogen-bonded with Arg196, and the 2-phenyl ring interacted with Phe347 via π-π stacking. The docking ...
He then persisted in rubbing his brown mole against mine. I’ve always thought my moles to be interesting and a feature that accentuates my beauty, a la Cindy Crawford. Hearing I should be paired off because (and I quote) of our ‘witchy hairy moles’ was actually offensive. For a ...
