Interaction Between a Drying Agent and Particles Dispersed by an Airstream Atomizer Inside a Drying Chamber

Results of an experimental study of the aerodynamics and spray density distribution of a liquid dispersed by an airstream atomizer inside a drying chamber. Velocity components of the drying agent and their radial distributions as a function of the distance from the spray plane are determined. Relationships for the distribution of dispersed liquid inside the drying chamber are derived. Interactions between the drying agent and the product in the drying chamber are analyzed.

Investigation of the Interaction of Sodium Chloride and Two Amino Sulfonic Acids,HEPES and MOPSO,by EMF Measurements

Ionic interactions in the two systems NaCl-HEPES (N-2-hydroxyethylpiperazine-N′-2-ethanesulfonic acid) and NaCl-MOPSO (3-(N-Morpholino)-2-hydroxypropanesulfonic acid) have been studied in terms of their mutual influence on the respective activity coefficients of each component. Activity coefficients for each component of the two systems and for corresponding buffers are calculated from emf measurements of solutions containing NaCl, the aminosulfonic acid, and its conjugate base in a NalSE/solution/AgCl-Ag cell at 5, 15, 25, and 37 °C.     

Study on Oxygen-Sensing Properties of LaNiO3 Thin Films

The synthesis of rare-earth perovskite-type composition thin films of LaNiO₃ by means of the inorganic-sol-gel (ISG) method was studied. The structural stability under high temperature in reducing atmospheres and the oxygen-sensitivity mechanism of the LaNiO₃ thin films were examined. It is shown that under the experimental conditions, LaNiO₃ decomposes and the valance states of nickel are +2 and +3.
