در این پژوهش پودرTiB2-TiC نانوکریستالی از راه روش جدیدی با عنوان سنتز احتراقی ماکروویو یا همان MACS (Microwave-Assisted Combustion Synthesis) تولید شد. ابتدا مخلوط پودری 3Ti + B4C به کمک آسیاب سیارهای تا 9 ساعت آسیاب شد. از پودرهای آسیاب شده جهت انجام واکنشMACS قرصهایی با قطر mm10 تهیه و از یک دستگاه ماکروویو خانگی با توانW1100 جهت سنتز استفاده شد. نتایج ناشی از آنالیزهای XRD و SEM نشان داد ...
in the past decades, many methods have been developed to synthesize zero- dimensional nanoparticles, quasi–one–dimensional (1d) cuo nanostructures, such as metal organic deposition technique, microwave irradiation, sol-gel-like dip technique, reverse micelle-assisted route, chemical method, and simple template free solution route. among those synthesis methods, hydrothermal and chemical reac...
Calcium phosphate [single-phase hydroxyapatite (HA), single-phase tricalcium phosphate (TCP), and biphasic HA-TCP] nanowhiskers and/or powders were produced by using a novel microwave-assisted “combustion synthesis (auto ignition)/molten salt synthesis” hybrid route. This work is an example of our “synergistic processing” philosophy combining these three technologies while taking advantage of t...
Well-defined 2D Eu+3 co-doped ZrO2: Gd+3 nanoparticles were successfully synthesized by microwave assisted solution combustion technique for luminescent applications. The present investigation reports the rapid and effective method for the synthesis of the Eu+3 co-doped ZrO2:Gd+3 nanoparticles and study of the luminescence behavior of Eu+3 ion in ZrO2:Gd+3 nanostructures. The optical properties...
Iodine determination in food samples was performed by inductively coupled plasma mass spectrometry (ICP-MS) after digestion by microwave-induced combustion (MIC). Sample masses up to 500 mg of bovine liver, corn starch, milk powder, or wheat flour were completely combusted using the MIC system. Ammonium nitrate (6 mol l(-1) solution, 50 μl) was used as an aid for ignition and vessels were charg...
The term green chemistry is defined as “the invention, design and application of chemical products and processes to reduce or to eliminate the use and generation of hazardous substances”. The major applications of green chemistry principles and practice renders control, regulation, and remediation, hence resultant environmental benefit can be expressed in terms of economic impact .It also invol...

2-Pyridones are important heterocyclic compounds that are widely used in medical chemistry, and their various derivatives have significant biological and medical applications. In this paper, the synthesis of 2-pyridones as well as 2-pyridone-based compounds, such as 2-quinolones, using microwave assisted organic chemistry is reviewed. The review is divided in three parts. In the first part, mic...
