“A novel charring agent (CNCA-DA) containing triazine and benzene ring, using cyanuric chloride, aniline, and ethylenediamine as raw materials, was synthesized and characterized. The effects of CNCA-DA on flame retardancy, thermal degradation, and flammability properties of polypropylene (PP) were investigated by limited oxygen index (LOI), vertical burning test (UL-94), thermogravimetric analysis (TGA), and cone calorimeter test (CCT). The TGA results showed that CNCA-DA had a good char forming ability, and a high find more initial temperature of thermal degradation; the char residue of CNCA-DA reached 18.5% at 800 degrees C; Ammonium polyphosphate (APP) could improve the char residue of APP/CNCA-DA system, the char residue reached 31.6% at 800 degrees C. The results from LOI and UL-94 showed that the intumescent flame retardant (IFR) containing CNCA-DA and APP was very effective in flame retardancy of PP. When the mass ratio of APP and CNCA-DA was 2 : 1, and the IFR loading was 30%, the IFR showed the best effect; the LOI value reached 35.6%. It was also found that when the IFR loading

was only 20%, the flame retardancy of PP/IFR can still pass V-0 rating in UL-94 tests, and its LOI value reached 27.1%. The CCT results demonstrated that IFR Oligomycin A supplier could clearly change the decomposition behavior of check details PP and form a char layer on the surface of the composites, consequently resulting in efficient reduction of the flammability parameters, such as heat release rate (HRR), total heat release (THR), smoke production rate (SPR), total smoke production (TSP), and mass loss (ML).

“One of the WHSC1/MMSET/NSD2 variant RE-IIBP is a histone H3-K27 methyltransferase with transcriptional repression activity.

Overexpression of RE-IIBP in various types of leukemia suggests it’s role in leukemogenesis. Here we identify two proteins, KRAB zinc finger protein ZNF 350 and enolase-1 as RE-IIBP interacting proteins by yeast two-hybrid screening and confirmed direct interaction in vivo and in vitro. Both proteins have been known for their role in transcriptional repression. Reporter assays using transient transfection demonstrated that both ZNF 350 and enolase-1 proteins synergistically repressed transcription with RE-IIBP, respectively. These results indicate both proteins have roles in RE-IIBP mediated transcriptional repression by involving co-repressor complex.”
“The magnetization structure and the mechanisms of magnetic interaction in an artificial two-phase magnet are analyzed with magnetic force microscopy and magnetooptics. A model system built up of arrays of hard magnetic CoPt squares (5 mu m edge length) embedded in a soft magnetic permalloy matrix is investigated.
