چکیده مقدمه: استفاده از زیرکونیوم به عنوان کور در ساخت روکش های دندانی با توجه به استحکام بالا، تطابق بافتی و در عین حال زیبایی آن موجب ارتقای پروتز های ثابت شده است. با این حال یکی از مشکلات اساسی در استفاده از روکش های بر پایه زیرکونیوم، تمایل کم زیرکونیا برای واکنش شیمیایی با پرسلن و سمان و در نتیجه باند ضعیف آن می باشد که موجب مشکلاتی از قبیل پریدگی و جداشدگی پرسلن می شود. هدف از مطالعه ح...

global air pollution is a serious threat caused by excessive use of fossil fuels for transportation. despite the fact that diesel fuel is a big environmental pollutant as it contains different hydrocarbons, sulphur and crude oil residues, it is yet regarded as a highly critical fuel due to its wide applications. nowadays, biodiesel as a renewable additive is blended with diesel fuel to achieve ...

The aim of this study was to investigate the synthesis of calcium aluminate cement with and without phosphate additive by combustion synthesis. After preparing the gel from a solution containing aluminum and calcium nitrates and glycine fuel and ammonium dihydrogen Phosphate, its combustion was performed at 400 ° C.  X-ray diffraction pattern and thermal analysis of the combustion sample showed...

Two-dimensional gel electrophoresis (2-DE) is widely applied and remains the method of choice in proteomics; however, pervasive 2-DE-related concerns undermine its prospects as a dominant separation technique in proteome research. Consequently, the state-of-the-art shotgun techniques are slowly taking over and utilising the rapid expansion and advancement of mass spectrometry (MS) to provide a ...

This paper presents a rheological study describing the effects of shear on the flow curves of colloidal gels prepared with different concentrations of fumed silica (4%, 5%, 6%, and 7%) and a hydrophobic solvent (Hydrocarbon fuel, JP-8). Viscosity measurements as a function of time were carried out at different shear rates (10, 50, 100, 500, and 1000 s−1), and based on this data, a new structura...

A special sensitive element based on the novel composite material was created. The sensor has a linear calibration and is resistant to aliphatic hydrocarbons, in particular aviation fuel. A low cost and easy-to-implement method for calibrating the sensor was proposed. Temperature dependence of the oxygen mass transfer coefficient kL was measured for aviation fuel TS-1 (Russi...

Nanocrystalline particles of barium hexaferrite has been prepared by the sol–gel auto- combustion method using iron and barium nitrate with a Ba:Fe molar ratio of 1:10. The effect of fuel such as citric acid and aspartic acid was investigated on the structure and magnetic properties of nanoparticles. The results revealed that the formation of barium hexaferritefine particles is influenced by mo...

In this study, Zinc oxide nanoparticles were synthesized by gel-combustion method using a novel bio-fuel tapioca starch pearls, derived from the tubers of Mannihot esculenta, to investigate the photocatalytic degradation of ccaffeine. The ZnO photocatalyst was characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), and UV-visible spectroscopy. X-ray diffractometry result f...
