PREPARATION AND CHARACTERIZATION OF A NEW NANO-SCALED MATERIAL COMPOSED OF BENTONITE-POLYETHYLENGLYCOPHTHALATE

Preparation and Characterization of A New Nano-scaled Material Composed of Bentonite-Polyethylenglycophthalate

In texstar peach this study a new composite material have been prepared and characterized through polymerization of ethylene glycol located between the Bentonite layers with phthalic anhydride.The results showed that the polymer binds with the structure of clay through hydrogen bonding also the polymerization process led to shatter of the three-dim

A distal intergenic region controls pancreatic endocrine differentiation by acting as a transcriptional enhancer and as a polycomb response element.

Lineage-selective expression of developmental genes is dependent on the interplay between activating and repressive mechanisms.Gene activation is dependent on cell-specific transcription factors that recognize transcriptional enhancer sequences.Gene repression often depends on the recruitment of Polycomb group (PcG) proteins, fr3622 although the se
