Clay minerals are considered the most important components of clastic reservoir rock evaluation studies. The Shurijeh gas reservoir Formation, represented by shaly sandstones of the Late Jurassic-Early Cretaceous age, is the main reservoir rock in the Eastern Kopet-Dagh sedimentary Basin, NE Iran. In this study, X-ray diffraction (XRD), X-ray fluorescence (XRF), scanning electron microscopic (S...

The co–polymer (Poly-ClBN) of 1, 2 Di-ChloroBenzene and Naphthalene has been synthesised. The copolymer (Poly-ClBN) has been characterised by X Ray Diffraction (XRD) and UV spectroscopic method. Thermo Gravimetric analysis (DTA, DTG and TG) has been used for analysis of thermal stability of the copolymer.

The technological aspects of modification epoxy oligomer DER – 331 to provide improvement thermophysical characteristics composite materials and protective coatings based on them are presented. Cold-cured triethylenetetramine TETA hardener was used crosslink the binder (q = 10 parts by weight per 100 DER-331 resin). Thermogravimetric (TGA) differential thermal (DTA) analysis performed study mod...
