طراحی و سنتز پلیمر های کئوردینانسیونی متخلخل یا چارچوب های فلز- آلی به علت ساختارهای جالب این ترکیبات و قابلیت های کاربردی آنها برای ذخیره و جداسازی گاز، کاتالیز، تشخیص و جداسازی انانتیومرها، خواص مغناطیسی، تنظیم لومینسانس و غیره توجه زیادی را به خود جلب کرده است. اخیرا مشخص شده است که برخی لیگاندهای آلی مسطح صلب مثل ایمیدازول-5،4-دی کربوکسیلیک اسید (h3idc) برای تشکیل چارچوب های فلز- آلی مناسب ...
DOR: 98.1000/2383-1251.1397.5.147.9.1.1578.41 Extended abstract Introduction: Quinoa, with the scientific name (Chenopodium quinoa Willd), belongs to the Spencer family. Seeds vigor can be improved with a variety of seed priming methods. In this method, the seeds are soaked in water or various osmotic solutions and then dried to the original moisture. After priming treatment, seeds are stor...
Due to the nature of their material properties, Calcium Fluoride (CaF2), Magnesium Fluoride (MgF2), and Potassium Dihydrogen Phosphate (KDP) are widely used for industrial purposes. A better understanding of the mechanical properties of these materials is of technological and scientific importance. The indentation nano-mechanical response of CaF2 (cubic), MgF2 (tetragonal), and KDP (tetragonal)...
Alkalinity of the soil is one of the main problems in some soils of Iran, which reduces the solubility and reduces the absorption of essential nutrients, including the iron element for the plant. Iron deficiency in plants reduces photosynthesis and reduces production. The present experiment, as a factorial, was conducted in the form of a statistical design of complete randomized blocks and in 3...
The aim of this article was to study the trans-epithelial absorption to reach the blood and to target the brain by axonal transport using nasal formulations with nanonized meloxicam (nano MEL spray) and its salt form known as meloxicam potassium monohydrate (MELP spray). The physicochemical properties and the mucoadhesivity of nasal formulations were controlled. In vitro and in vivo studies wer...
Background: Prior research demonstrated that via a novel technique it was possible to obtain ex vivo hair tissues magnetic profiles based on microscopic nano-sized iron particles detected by Prussian Blue Stain (PBS). The present study demonstrates that magnetic signals emitted by both the ex vivo and in vivo hair follicles could penetrate glass barriers. Methods: Two different versions of Prus...
The effect of potassium iodide (KI) and sodium nitrite (NaNO₂ inhibitor on the corrosion inhibition of mild steel in chloride bicarbonate solution has been studied using electrochemical techniques. Potentiodynamic polarisation data suggest that, when used in combination, KI and NaNO₂ function together to inhibit reactions at both the anode and the cathode, but predominantly anodic. KI/NO₂- conc...
در این رساله، طراحی، اجراء و مدلسازی فرآیند nano-edm مورد بررسی و تحقیق قرار گرفت. به منظور تولید نانو- ابزار مناسب برای فرآیند nano-edm یک دستگاه اتوماتیک طراحی و ساخته شد که با استفاده از آن، تاثیر متغیرهای فرآیند ساخت بر خصوصیات نانو- ابزار مورد تحقیق قرار گرفت. با شناسایی سطوح بهینه متغیرهای فرآیند ساخت به روش تاگوچی، نانو- ابزارهایی با شعاع نوک حدود 10 نانومتر و ضریب جانبی (نسبت طول به شعا...
metal—polyaniline nanocomposites such as platinum-polyaniline nanocomposite is prepared by insitu oxidative polymerization of aniline and reduction of pt+4 ions into pt nanoparticles. thepolymerization of aniline was carried out in the presence of 1(2ptcn6 [potassium hexa cyanoplatinate (iv)] as oxidizing agent. during the reaction aniline monomers undergo oxidation andform polyaniline (pant) w...
The immobilization of potassium sorbate, potassium aspartate and sorbic acid in layered double hydroxide under solid condition was examined. By simply mixing two solids, immobilization of sorbate and aspartate in the interlayer space of nitrate-type layered double hydroxide, so called intercalation reaction, was achieved, and the uptakes, that is, the amount of immobilized salts and the interla...
