... potassium nitrate solution (3.4 mol KNO 3 /kg D 2 O), using nitrogen and oxygen isotopes on the nitrate-N or nitrate-O sites ( F ig . 1 top left ). Historically, NDIS measurements with oxygen isotopes ( 18 O vs. 16 O) were not thought to be possible because the difference in scattering would be too small...

... the necessity of deconvolution and fitting of overlapping peaks. Here we used mixtures of sodium oxalate + potassium nitrate and calcite + gypsum. For each mixture, a series of five lines of 30 points were analyzed for a set of up to nine proportions ranging from 1 % to 99 % in weight. In total, 1350 points...

A reasonable assumption, based on these results, is that the clay minerals play a significant role in the nitrogen cycle, but no further studies have been reported on the reactivity of Fe-bearing clay minerals toward...

The refined water content of 14 H 2 O per unit cell of the K-NAT is significantly smaller than 20.6 H 2 O of Yamazaki’s. Our preliminary results show that the channel water content in the water-disordered natrolite is very...

The reaction of sodium sulfate with calcium nitrate and ammonium dihydrogen phosphate produced sulfated calcium hydroxylapatites (SCaApOH) containing 2 to 8 wt% sulfate. The relationship between the weight percent sulfate in the apatite and the mole ratio...

... accurately. It does not contain potassium and is close to the chemical formula NH 4 MgCl 3 ⋅6H 2 O. Novograblenovite from Radlin is also analogous to a phase described from burning coal dumps in Chelabinsk, Russia and informally named ‘redikortsevite’. Therefore this name should be abandoned. Our...
