densities and viscosities of chromium trioxide Potassium chromate Potassium Dichromate water from 298 15 to 333 15 k
Journal of Chemical & Engineering Data, 2008Co-Authors: Ji-yan Wang, Fu'an Wang, Peng Zhang, Bao-zeng RenAbstract:Densities and viscosities of chromium trioxide + Potassium chromate + Potassium Dichromate + water quaternary mixtures and Potassium chromate + Potassium Dichromate + water ternary mixtures have been measured from (298.15 to 333.15) K. The dependence of density and viscosity on temperature and concentration has been correlated. Apparent molar volumes, standard partial molar volumes, and the viscosity B-coefficient of chromium trioxide were calculated from the experimental measurements. The solute-mixed solvent interaction, solute–solute interaction, and structure-making effect of chromium trioxide have been discussed using the Helper equation and the Jones−Dole equation. The relationship between relative changes in viscosity and solute-mixed solvent interaction has been probed.

influence of collagen macromolecular arrangement on the Potassium Dichromate spiral crystal growth
Journal of the Physical Society of Japan, 1998Co-Authors: Junichiro Suda, Tomoo Nakayama, Mitsugu MatsushitaAbstract:We have studied the effect of salts, adenosine triphosphate (ATP) and glycoprotein on the growth of huge right-handed spiral crystals of Potassium Dichromate (K 2 Cr 2 O 7 ) in gelatin gel. These materials are known to induce, respectively, amorphous, short-range and long-range arrangements of collagen macromolecules that constitute the gelatin-gel network. It was revealed that both salts and ATP have a clear tendency to reduce the spiral growth of K 2 Cr 2 O 7 , while glycoprotein strongly enhances it. These results suggest that not only the existence of collagen macromolecules with right-handed triple helix structure but also their long-range arrangement is essential for the spiral growth of K 2 Cr 2 O 7 .

morphological diversity in the crystal growth of Potassium Dichromate in gelatin gel
Journal of the Physical Society of Japan, 1996Co-Authors: Junichiro Suda, Tomoo Nakayama, Akio Nakahara, Mitsugu MatsushitaAbstract:Potassium Dichromate (K 2 Cr 2 O 7 ) grown in gelatin has been found to exhibit five morphological phases, i.e., right- or left-handed spiral, spherulite, square polelike, platelike and DLA-like crystals when varying the initial concentrations of K 2 Cr 2 O 7 and gelatin. The results are summarized in a morphological phase diagram. Although we reported in our previous letter that spiral crystals obtained were all right-handed, only a few left-handed spiral crystals have also been observed in a specific subregion of the spiral growth region in the phase diagram. Square polelike crystals have shown tendency to grow and fuse together side by side in a region adjacent to the spiral growth in the phase diagram. This strongly suggests that spirals are composed of small square polelike crystals fused together. It is conjectured that right-handed triple helices of collagen molecules constituting gelatin-gel perturb the growth process to form right-handed spirals obtained mainly in the present experiments.

spiral crystal growth of Potassium Dichromate in gelatin
Journal of the Physical Society of Japan, 1995Co-Authors: Jun Suda, Mitsugu MatsushitaAbstract:Huge spiral crystals of Potassium Dichromate (K 2 Cr 2 O 7 ) have been found to grow three-dimensionally in a gelatin medium when gelatin containing K 2 Cr 2 O 7 was dried slowly in a test tube at a low temperature. These spirals were all right-handed, and their widths, axial pitches and lengths were 2–3 mm, 5–6 mm and 20–25 mm, respectively. When the gelatin concentration in the medium was decreased, ordinary platelike crystals were observed to grow, instead of the spiral crystals. To the best of our knowledge, inorganic compounds such as K 2 Cr 2 O 7 have so far not been reported to form such huge spiral crystals. It is conjectured that collagen molecules, which compose the gelatin medium and have right-handed triple helix structure lead to the growth of spiral crystals.
