in the present work, a simple and sensitive method was developed for determination of morphine and heroin using gold nanoparticles as resonance rayleigh scattering (rrs) and colorimetric technique’s probe. synthesized gold nanoparticles by sodium citrate reduction method have a negative charge layer on their surfaces because of self-assembled citrate anions on their surface. binding of morphin...
The process of the phase transformation from amorphous to crystalline FePO4·2H2O was studied in this research. It found that Fe and P are predominantly present as FeHPO4+ FeH2PO42+ an induction period exists during transition monoclinic form. time required for were shortened with increased temperature. Phase could be kinetically described by Johnson–Mehl–Avrami (JMA) dynamics model. dissolution...
A study was conducted to compare the effects of iron hydrogen phosphate nanoparticles (FeHPO4) with iron sulfate (FeSO4-7H2O) on growth performance, carcass characteristics and mineral content of breast muscle in broiler chickens. A total of 200 one-day-old male Ross 308 broiler chicks were assigned randomly into four dietary groups with five replications of ten...
nanotechnology is a general term which is related with field of all advanced science term that generally predicates with all modern technologies which consider nanoscales. improvement in the quality of products by adding some nanoparticles and study of their behavior in the presence of these nanoparticles have been obtained in many researches. on the other hand numerous demands for sowing ...
a novel acrylic acid-functionalized fe3o4 magnetic nanoparticle with a core-shell structure was developed for utilization as a heterogeneous organosuperacid in chemical transformations. the structural, surface, and magnetic characteristics of the nanosized catalyst were investigated by various techniques such as transmission electron microscopy (tem), thermogravimetric analysis (tga), and ft-ir...
here, we report analysis of in vitro and in vivo drug release from an in situ formulation consisting of triamcinolone acetonide (tr) and poly(d,l-lactide-co-glycolide) (plga) and the additives glycofurol and hydroxyapatite nanoparticles (ha). we found that these additives enhanced drug release rate. we used the taguchi method to predict optimum formulation variables to minimise the initial burs...
در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...
recent investigations have been shown that inorganic nanomaterials including gold nanoparticles, nonporous and mesoporous silica nanoparticles, magneticnanoparticles, and quantum dots have shown great potential in bioimaging, targeted drug delivery, and cancer therapies. biocompatibility, ease of synthesis, and ease of surface functionalization are among the significant properties of nonporous ...
مدارات مجتمع نوری نیازمند ساختارهایی هستند که با ابعادی زیر حد پراش نور بتوانند انرژی الکترومغناطیسی را هدایت کنند. این ویژگی با بکارگیری موجبرهای معمولی یا بلور فوتونی بدست نمی¬آید. بنابراین موجبرهای پلاسمونی برای هدایت انرژی الکترومغناطیسی زیر حد پراش نور پیشنهاد شده¬اند. در این پایاننامه، ویژگی های نوری فلزات و پلاسمون¬های سطحی روی مرز فلز ودی¬الکتریک به طور کامل شرح داده¬شده¬است. تحلیل موجب...
in this study, a set of experiments were conducted to investigate the influence of edta-grafted iron oxide nanoparticles exposure on agronomic traits of sunflower (helianthus annuus) plants. the experiment was implemented by applying nano-fe3o4-edta and fe-edta fertilizers applied through spray or soil amendment. a variety of parameters including aerial organ biomass, number of leaves, plant he...
