Adsorption of Methylene Blue Dye on Hydrothermally Prepared Tungsten Oxide Nanosheets

Autor: Nazly Hassan, Hesham M. A. Soliman, Ahmed Salah Doma, A.I. Abd-Elhamid

Publikováno v: Egyptian Journal of Chemistry. 63:483-498

Methylene blue (MB) dye was successfully adsorbed on hydrothermally prepared tungsten oxide nanosheets. SEM, XRD, FTIR and EDS were used for characterization of the prepared powder. Different parameters affecting the adsorption process such as, conta

Influence of degree of substitution and folic acid coinitiator on pullulan-HEMA hydrogel properties crosslinked under visible-light initiating system

Autor: Elbadawy A. Kamoun, M.A. Abu-Saied, Henning Menzel, Xin Chen, Ahmed Salah Doma

Publikováno v: International Journal of Biological Macromolecules. 116:1175-1185

Hydroxyethyl methacrylate-derivative pullulan (pullulan-HEMA) was synthesized by activation of HEMA followed by catalyzed reaction for adjusting the degree of substitution (DS) of copolymer. Pullulan-HEMA was photocrosslinked using new three-componen

Compatibilization of Vulcanized SBR/NBR Blends using Cis-Polybutadiene Rubber: Influence of Blend Ratio on Elastomer Properties

Autor: Mohammed A. Belal, Sherine N. Khattab, Elbadawy A. Kamoun, Ali A. El-Bardan, S. Abboudy, Ahmed Salah Doma

Blends composed of styrene butadiene rubber (SBR) and acrylonitrile-butadiene rubber (NBR) were fabricated by melt blending technique using two-roll mill blend machine. Cis- polybutadiene rubber (CBR) was used as a compatibilizer for enhancing the ho
