Research ArticleOpen accessEvery word in the titleSynthesis, Characterization and Saponification of Poly (AN)-Starch Composites and Properties of their HydrogelsA. Hashem, M. A. Afifi, E. A. El-Alfy, A. HebeishHydrogels based on saponified products of poly (acrylonitrile, AN)-starch composites were prepared, characterized and their water abosrbency properties examined. The term composite refered to the resultant products of polymerizatin of AN with starch in presence of ceric ammonium nitrate (CAN) as initiator, that is the composite consists of poly(AN)-starch graft copolymer, homopoly(AN) , oxidized starch and unreacted starch. Thus AN … …American Journal of Applied Sciences, Vol. 2, Issue 3 · 31 Mar 2005 · 7,577 accessesView PDF Cite

Research ArticleOpen accessEvery word in the titleControlled Delivery System for NPK Agrochemical Release from Chitosan Copolymer HydrogelsMaysam S. Mutlaq, Fawzi Habeeb JabrailChitosan (CS) the polysaccharide was copolymerized with Poly (Vinyl Alcohol) (PVA) for the preparation of CS-co-PVA hydrogel and with Carboxymethyl Cellulose (CMC) for CS-co-CMC hydrogel. The prepared hydrogels were characterized by FTIR, thermal analysis (TGA and DSC), and SEM. The hydrogels were studied for agriculture applications, where their ability to swell and take large quantities of water many times its … …American Journal of Applied Sciences, Vol. 19, Issue 1 · 8 Sep 2022 · 6,746 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsControlled Release Behaviors of Tribenuron Methyl Herbicide and Potassium Nitrate Fertilizer from Natural Polymer Blended Poly(Vinyl Alcohol) Hydrogel MicrospheresFawzi Habeeb Jabrail, Wajeeh Mohammed Jamil, Maher Zeki Elsabee, Kailash Chandra GuptaPolyvinyl Alcohol (PVA) hydrogel microspheres for controlled release of fertilizer (KNO3) and Tribenuron Methyl Herbicide (TBM) were prepared by blending the naturally occurring Alginate (AL) and Pectin (PE). The cross-linking in PVA hydrogel microspheres was carried out by varying the amount of glutaraldehyde from 0.5-1.0 wt%. To control the loading and release properties of PVA hydrogel microspheres, a small amount … …American Journal of Applied Sciences, Vol. 16, Issue 5 · 13 Jul 2019 · 7,673 accessesView PDF Cite

Research ArticleOpen accessIn the abstractFunctional Evaluation of Polydioxanone Threads Coated with Polyethylene Glycol and Amino Acids for Medical ApplicationEunji Park, Tae Su Jang, Jae Kyung KimPolydioxanone (PDO) is a biodegradable polymer with multiple medical applications. Recently, various coatings have been applied to products made of biodegradable polymers, in order to improve functionality. Polyethylene Glycol (PEG) hydrogels have demonstrated remarkable potential in accelerating wound healing and amino acids have been reported to stimulate protein synthesis in vivo and in vitro. The purpose of this study was … …American Journal of Biochemistry and Biotechnology, Vol. 20, Issue 2 · 24 May 2024 · 5,599 accessesView PDF Cite

Research ArticleOpen accessIn the abstractPrevention of Desertification and Land Degradation using Black Saxaul in Arid ConditionsBirzhan Yessimbek, Bulkajyr Mambetov, Ruslan Akhmetov et al.The harsh climate of the arid zone determines several biological features in black saxaul plantations. Therefore, the study of the growth and condition of artificial plantations, depending on the use of physiologically active moisture-absorbing substances and growth biostimulants, is of particular practical importance. In the Moinkum sands of the Zhambyl region (Kazakhstan), observations of the growth and development of the … …OnLine Journal of Biological Sciences, Vol. 22, Issue 4 · 22 Nov 2022 · 5,516 accessesView PDF Cite
