    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] THERE is considerable difference of opinion regarding the possibility of the oxidation of nitrites by oxygen to nitrates. Berzelius reported that when aqueous solutions of alkali nitrites are boiled in air, they absorb oxygen with the formation of nitrates. G. Lunge and E. Frémy, J. ...

    Notes: [Auszug] WHEN freshly collected cow-dung (containing 0.368 per cent nitrogen and 7.5 per cent carbon) is mixed with soil and exposed to sunlight daily for six hours in dishes, nitrogen fixation is observed. Thus the nitrogen content of a mixture containing 500 gm. soil and 100 gm. cow-dung rose from ...

    Notes: [Auszug] THE ordinary denitrification taking place in the absence of oxygen and in presence of an easily oxidisable organic substance and a nitrate effected by many micro-organisms, is well known. There is another variety of nitrogen loss, which takes place in presence of oxygen, but has not yet been ...

    Notes: [Auszug] IN recent publications1, it has been shown that the absorption of light by a mixture of two reacting substances is greater than the absorptions of the reacting substances considered separately. Thus the absorption in the visible and ultra-violet regions by a mixture of N/400 ...

    Notes: [Auszug] RECENTLY we have been successful in synthesising amino acids by exposing solutions of glycol or glucose and nitrates to sunlight for six to eight hours in presence of titania, used as a photocatalyst. The amino acids formed can be estimated colorimetrically by the valuable ‘ninhydrin’ ...
