Evidence of deeply supercooled liquid water in interaction with LiCl

Article Abstract:

The compositional change of the pure amorphous solid water (ASW) films deposited on the LiCl film is analyzed by using time-of-flight secondary ion mass spectrometry (TOF-SIMS) in the temperature range 140-155 K. Two phases of deeply supercooled water that lead to the dilute and concentrated LiCl solutions are clearly identified, where the former is short-lived and merges into the latter and the latter is basically identical to normal liquid water as far as the solubility of LiCl is concerned.

Sintering and crystallite growth of nanocrystalline copper doped tin oxide

Article Abstract:

The effects of Cu(II) addition and firing temperature on the sintering and crystallite growth of nanocrystalline SnO2 xerogels are studied via thermoanalysis. Results show that increasing amounts of copper reduces the shrinkage associated with mass loss. Copper is observed in substitutional solid solution for dried xerogel prepared with 0.7 mol % of copper. Crystallite growth also results from recrystallization near 320 degrees Centigrade.
