    Notes: Summary Capillary Pumped Loop (CPL) is a thermal management device for advanced spacecrafts. This paper presents the operating principles of a CPL and the design characteristics of the components. Another purpose of this experiment was to build up a transparent loop in order to better determine and observe the internal thermofluid dynamics. The results indicated that the CPL could be in normal operation under various heat modes. Observation also told Non-Condensed Gas (NCG) was moving and collecting to somewhere between the condenser section.

    Notes: Changes in the rheological properties of chitosan solutions with pH, ionic strength, and type of anion were studied. Between pH 2.0 and 5.0, apparent viscosities increased with the decrease of pH in chitosan-organic acid solutions, while in chitosan-HCl solutions they behaved oppositely. In chitosan-NaOH solutions, they decreased with the increase of pH between pH 5.0 and 6.0, then increased as pH further increased to pH 6.0-6.4. The difference may be due to different interactions of counterions with macroions and also the third electroviscous effect. Relative viscosity increased with a decrease in chitosan concentrations at concentrations below 1.5 × 10-3 M. Intrinsic viscosities changed with media pH and ionic strength.
