Nano Fe2O3 were added into polypropylene (PP) / ammonium polyphosphate (APP) / melamine phosphate (MPOP) / 1-oxo-4-hydroxymethyl-2,6,7-trioxal-phosphabicyclo-[2.2.2]octane (PEPA) to prepare intumescent flame-retarded nanocomposites. The flame retardance and thermal stabilization and intumescent char layer have been investigated by UL-94 test, TGA and SEM. Result showed that the behavior of this intumescent system can be enhanced significantly by the addition of small amounts of nano Fe2O3. TGA results present higher thermal stability of the PP-IFR-Fe2O3 in high temperature when compared with the PP-IFR. SEM indicated the char layer from the PP-IFR-Fe2O3 system has a compact and tough char structure compared with the PP-IFR. Adding 0.3 wt% and 27 wt% IFR into PP, the PP-IFR-Fe2O3 system provided good fire retardant behavior, mechanical properties and achieved UL94 V-0 rating.

      Thirty specimens of fresh white cheeses, presented for sale in different markets at different cities of Iraq were analyzed microbiologically in this study.   Isolates of Salmonella, included in the specimens collected from November 2017 to January 2018, were investigated. Capacity for biofilm producing was demonstrated by two method, Tissue culture plate method (TCP) and Congo red agar (CRA).After that the antibiofilm activity of lime extract and LiO2NPs was studied as each one of them alone and then the synergistic effect was done by TCP method. The results showed that all Salmonella isolates produce biofilm but in different degrees. The results also displayed that Lime extract and LiO2NPs had antibiofilm effect against Salmonella when used alone and when the combination done between each one of these materials. In conclusion, it was observed that the specimens of fresh white cheese included in this study contained microbial contamination at a health-threatening level but we can eliminate this contamination by using lime extract and LiO2NPs.
