...of unfilled homopolymer acetal (Delrin) is approximately 15%% greater than the co-polymer acetals. Hot Water/Steam Resistance: Copolymer acetals exhibit substantially greater resistance to hydrolysis (degradation by hot water) and better dimensional stability, especially after prolonged exposure. Chemical Resistance: In general, the chemical resistance is similar; however, it may...

... yielded between 1000- 1,500 fragments of DNA, each of 100 base pairs in length. These samples, obtained from a specimen dated at about 40,000 years old, had been degraded by hydrolysis and oxidation, and were contaminated with DNA from bacteria and fungi which start to decompose the body soon after death. Furthermore, neanderthal DNA is often contaminated with the DNA of those who excavated...

... the problem of bases. Excerpt: Results As condensation of sugar phosphates and nitrogenous bases is thermodynamically unfavorable, these compounds, if ever formed, should have undergone rapid hydrolysis. Thus, formation of oligonucleotide- like structures could have happened only if and when these structures had some selective advantage over simpler compounds. It is well known that ...

...condensation reactions proceed with release of water, so that the presence of latter favors hydrolysis of biological polymers. Because of this feature, Bernal [27] and many researchers ... bases is thermodynamically unfavorable, these compounds, if ever formed, should have undergone rapid hydrolysis. Thus, formation of oligonucleotide- like structures could have happened only if and when these ...

...have a subscription. But I'm curious. According to the abstract, they say that due to hydrolysis of HCN, the steady state ocean concentration would not rise above about 10^-12 M. I ... for dissolved transition metals. I would think that ligated HCN would be relatively well protected from hydrolysis. Similarly, it would seem to me that if there are significant amounts of HCN (and CO) ...

..., there's no residue after a good wash and oven-bake. I'd use it straight. I suggested alkali (like carbonate; should have mentioned TSP as well) because it can chemically chop up the gunk by ester hydrolysis. Vinegar would be acting mainly as a solvent. 6%% acetic acid isn't a very good one for that kind of thing, so I'd lean hard on the alkali first. I do work for a university so...
