This study compared magnesium oxide and magnesium citrate with respect to in vitro solubility and in vivo gastrointestinal absorbability. The solubility of 25 mmol magnesium citrate and magnesium oxide was examined in vitro in solutions containing varying amounts of hydrochloric acid (0-24.2 mEq) in 300 ml distilled water intended to mimic achlorhydric to peak acid secretory states. Magnesium o...
Porous nickel oxide films were prepared by electrochemically precipitating nickel hydroxide and heating the hydroxide in air at 300°C. The resulting nickel oxide films behave as an electrochemical capacitor with a specific capacitance of 59 Flg electrode material. These nickel oxide films maintain high utilization at high rates of discharge (i.e., high power density) and have excellent cycle li...
nano-sized drugs have better distribution than their identical forms. magnesium is the cofactor of various enzymes in lipid and glucose metabolism. in this study the effect of nano-magnesium oxide (nano-mgo) on glucose concentration and lipid profile in diabetes induced mice was evaluated in 21 laboratory mice. mice were divided randomly into three equal groups (control, treatment and placebo)....
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 ...
Future large-scale production of H2 for use as a clean fuel will likely depend upon gasifying coal or biomass followed by steam reforming the resulting gas mixture and separating the CO2 byproduct. The process of steam reforming and CO2 separation can be greatly simplified by utilizing a new material that combines a reforming catalyst with a sorbent for CO2. Such a material was prepared in the ...
Nanostructures of magnesium oxide is one of the most attractive materials which have shown various applications in many aspects of industries. So, finding a controllable and inexpensive technique to produce desirable nanostructures of MgO is valuable. In this work, magnesium oxide (MgO) with different morphologies was successfully prepared via a simple solid-state method. The molar ratio of sod...
mesoporous mgo microstructures were synthesized using magnesium acetate tetrahydrate, ammonium oxalate monohydrate and pluronic f127 via heating at 40 °c for 24 h and subsequent calcination. the mesoporous structure of magnesium oxide with the specific surface area of 47m2/g, pore volume 0.30 cm3/g and the average pore size 24 nm is produced. according to xrd stu...
background: in this study, adsorbentn process performance was assessed using nickel oxide nanoparticles for wastewater treatment containing mono azo orange ii dye in a laboratory scale. methods: the effects of various factors such as adsorbent dosage, contact time, ph and initial dye concentration were investigated. findings: based on the obtained results, the optimum ph range to dye removal is...
