In this work, new acrylate cyclotriphosphazene moiety (PN-A) was successfully synthesized starting from (PN) compound. This compound reacted with 2-hydroxyethylacrylate utilizing 1:1 mole ratio to increase the priority of one substitution reaction and forming PN-A molecule. The crud product purified by recrystallization using n-hexane column chromatography cyclohexane: ethyl acetate 60:40 mL as...
چکیده : * در یک واکنش تک ظرفی و با استفاده از واکنش آلدهید های آروماتیک و 3- متیل 1- فنیل پیرازولین-5- ان با نسبت مولی 1:1، ساختارهای هتروسیکل پیرازول سنتز شد. از مزایای آن، انجام واکنش در دمای اتاق، عدم نیاز به کاتالیزور، بازده بالای واکنش، استفاده از آب بعنوان حلال سبز و بی خطر به جای حلال های آلی وسمی می باشد . * توانستیم با استفاده از ملدرام اسید ومشتقات 2- هیدروکسی بنزآلدهید، ترکی...
Preparation of composite powders with uniform dispersion, high sphericity, suitable particle size and distribution is a great concern in fabricating high-performance components via additive manufacturing. Herein, we developed novel technology, namely freeze-dry pulsated orifice ejection method(FD-POEM), to prepare monodispersed spherical particles. Taking ZrO 2 nano-powders as an example, high-...
The interactions of mono-rhamnolipids (mono-RLs) with model membranes were investigated through a biomimetic approach using phospholipid-based liposomes immobilized on gold substrate and also by the multiparametric surface plasmon resonance (MP-SPR) technique. Biotinylated bound onto an SPR chip coated streptavidin layer. resulting MP-SPR signal proved efficient binding liposomes. thickness lip...
this research concentrates on the lithostratigraphy, biostratigraphy, microfacies and sedimentary environment of the asmari and gachsaran formations at southwest firuzabad. the thickness of the studied section in all 608.95 meters that 220.8 meters belong to the asmari formation and 387.95 meters belong to the gachsaran formation (champe and mol members). in the study area, the asmari formation...
background: type 2 diabetes is a common disorder recognized as a major health problem in iran. diabetes is a major source of morbidity, mortality and economic cost to society. diabetic patients are at risk of experiencing macrovascular and microvascular complications of diabetes. the aim of this study was to assess the prevalence of type 2 diabetes complications and their contributing factors. ...
a series of novel 2-aminopyrimidine and 2-substituted-4,6-diaminopyrimidine derivatives have been synthesized and their anti platelet aggregation activities were assessed against adp and arachidonic acid- induced platelet aggregation in human plasma using light transmission aggregometry. none of the compounds showed satisfactory activity against the aggregation induced by adp. however, satisfac...
