Packaging foods with antibacterial electrospun fibrous mats, in particular the incorporation of bacteria specific viruses such as bacteriophages may address concerns triggered by recent waves of bacterial food contamination. The presence of a precipitate in equilibrium with a rich oil micro-emulsion and several liquid crystalline structures with birefringent properties are some indicators of a not typical phase. Nanoencapsulation is defined. " ebook Physical Review Letters 63.
January 1999, Special INTAS session wihtin the framework of the Fourth Russian Symposium (with International attendance) "Liquid Crystalline and Related Polymers", Moscow, Russia. The real phase behavior Is more complex than that since several middle-phase compositions are founded rather than a single point.
