Potentials and Usage
Ice III can be used in the high pressure induced crystallization (HPIC) processes after been treated with the effect of pressure treatments at -25°C and 150 to 300 MPa. The transient phase that converts ice I to ice III during the pressurization process of frozen systems has been a potential to work as a food application. Its formation due to this treatment will occur during the pressurization, which can be used to inactivate some beneficial micro-organisms of frozen food, such as strawberries and carrots which are chosen as cases for the experiments. In the case of carrots, blanching was required for the inactivation of enzyme-related food qualities. As for the bacterial suspension, a phase transition from bacterial contamination. Some experimented bacterial contaminants include Listeria innocua and Bacillus subtilis. Treatment under the condition of 300 to 400 MPa and -45°C to the contaminant of Listeria innocua in phosphate-buffered saline solution can result in a 3 log cycle inactivation. For Bacillus subtilis, a pressure treatment at 250 MPa and higher than -25°C is the most effective. In addition, it can be the dependence of thermal structured matrices. In contrast to high-pressure freezing and thawing processes, HPIC processes seem to be more effective for microbial sample experiments confirmed that the optimal temperature range during HPIC processes for the formation of ice III in frozen strawberries and carrots is 250 to 300 MPa.

Physical Properties
Ice III have lower hexagonal symmetries than ice Ih and Ic, meaning that it has a slower proton diffusion rate than that fo the other two. Being the lowest density phase-out of the other high-pressure phases, it also has a smaller energy barrier than that of higher density structures based on the Arrhenius plot of diffusion coefficients which will increase with temperature. Subjects to lower temperatures and high pressures, ice III can be supercooled to below -65°C where it can begin to transform into ice IX which is proton ordered and antiferroelctric.

My media is the sketching of a mouth and a nose. It is my own work because I did the sketchings based on my impression of a real human facial organ. The file format is JPEF. The licence I have chosen is the less restrictive license: {selflcc-by-4.0}. I will add it to the Sketching category.
