“…We have presented a novel freeze concentration method that uses ice nucleation-active bacterial cells as effective ice nuclei in order to obtain condensed materials under a mild condition. 1) The Food and Drug Administration (FDA) standard 2 ) states that strawberry jam should possess refractive index of 65°, total acid content of more than 0.3%, and pH of less than 3.5. In practice, strawberry paste is mixed with granulated sugar and then evaporated by heating under an atmospheric environment.…”

Beta-SiC (cubic phase) nanowires (SiCNWs) have been grown spontaneously during the autothermal selfpropagating high-temperature synthesis (SHS) from elemental silicon and poly(tetrafluoroethylene) (PTFE) powder mixtures in oxygen-enriched atmosphere. The combustion process was on-line monitored using highspeed photography in order to estimate the reaction processing time which was well below 1 s. From the emission spectroscopy the averaged combustion temperature was evaluated to be close to 2000 K. The products were characterized by wet chemical analysis, X-ray diffraction, scanning and transmission microscopy, and Raman spectroscopy. The raw products were processed by wet chemistry to obtain pure (above 90%) well-crystallized one-dimensional single crystals of SiCNWs.

Progressive freeze concentration (PFC) is a process where only a large single ice crystal is formed in the system and grown on the cooling surface so that the separation between the ice crystal and the mother solution is very easy. This makes the system very simple and leads to a lower cost. The conventional setup of PFC produces ice with high purity but lower productivity than suspension freeze concentration (SFC). The volume of ice produced is also usually low. Hence, continued areas of the development for PFC system include the quest for improved productivity and better efficiency. Different kinds of design have been investigated which are easy to operate and cost-effective besides the ability to obtain high quality of product and better efficiency of the system. The PFC system is recognized as a good alternative if high quality products can be produced with higher productivity. In this article, previous researches on PFC designs were reviewed for the purpose of providing an understanding on methods of designing a PFC system and also to provide references for future application of PFC.
