Ethanol Best Quotes

It's just nature," I point out, wiping my lab bench, the sweet smell of the ethanol solvent. "Put animals in a small, closed space, and the one with the sharpest nails, the pointiest teeth wins." He gins. "Or maybe it's just like musical chairs?" It's a luxury to view it so lightly. But I nod. It's best never to let them see your teeth.

Glib advice aside, what is the recommendation when it comes to sleep and alcohol? It is hard not to sound puritanical, but the evidence is so strong regarding alcohol’s harmful effects on sleep that to do otherwise would be doing you, and the science, a disservice. Many people enjoy a glass of wine with dinner, even an aperitif thereafter. But it takes your liver and kidneys many hours to degrade and excrete that alcohol, even if you are an individual with fast-acting enzymes for ethanol decomposition. Nightly alcohol will disrupt your sleep, and the annoying advice of abstinence is the best, and most honest, I can offer.

Power generation through renewable energy has to be increased from 5 per cent to 28 per cent. Dependence on fossil fuels as primary energy source needs to be brought under 50 per cent from the present 75 per cent. Mandating the use of ethanol from 10 per cent to 20 per cent and the associated public policy for ethanol development by the sugarcane industry is also required. There is also a need for a sustainable biofuel policy for generating 60 million tonnes of biofuel, along with the use of alternate sources such as emulsification, bio-algae and hydrogen fuel.

How long is it before those new memories are finally safe? We actually do not yet know, though we have studies under way that span many weeks. What we do know is that sleep has not finished tending to those newly planted memories by night 3. I elicit audible groans when I present these findings to my undergraduates in lectures. The politically incorrect advice I would (of course never) give is this: go to the pub for a drink in the morning. That way, the alcohol will be out of your system before sleep.

The hangover is actually multifactorial. Dehydration plays an important role, as does hypoglycemia caused by the alcohol-mediated loss of sugar in the urine. But, in all likelihood, the greatest contributor to the hangover is methanol. This alcohol is found in small concentrations in many beverages; it’s a by-product of fermentation. Methanol is metabolized by the same enzymes as ethanol, but the products this time are formaldehyde and formic acid, which produce the hangover symptoms. Why does this happen only the morning after? Because the enzymes prefer to work on ethanol instead of methanol. Only when all the ethanol has been metabolized do they switch to methanol. This then explains the “hair of the dog†hangover remedy. A drink in the morning supplies ethanol for the enzymes to act upon so they’ll leave the methanol alone. As the enzymes busily metabolize the ethanol, methanol is excreted in the urine without being converted to formic acid. A Bloody Mary may be the best choice here, because vodka contains very little methanol. Confirmation of the critical role methanol plays in hangovers comes from a study showing that treatment with 4-methylpyrazole, a drug that blocks the breakdown of methanol, can eliminate the symptoms.

The best performing biofuel, sugarcane ethanol, widely used in Brazil, requires 400 times more land to produce the same amount of energy as petroleum.
