The lithium ion-ion interactions in protic ionic liquids can be very different compared to those in aprotic ionic liquids. In this study we show that, for equal lithium ion concentration, the lithium coordination number in protic ionic liquids is lower than that in aprotic ones. This lower coordination makes lithium ions more "free" to move in protic ionic liquids and it might have an important...

Interfacial effects in (room temperature) ionic liquids at charged surfaces are very important for ionic liquids applications in electrochemistry,1 energy storage,2 catalysis3 and other areas (e.g., lubrication4,5). However despite the many articles published on this subject (several hundred papers just in 2013) there is still no general agreement in the literature about the main factors that g...

مایعات یونی کاربردهای فراوانی در علم وتکنولوژی دارند. مزیت اصلی آنها که بعنوان حلال استفاده میشوند، فشار بخار پایین آنهاست و بهمین علت دوستدار محیط زیست هستند. مایعات یونی بعنوان حلال برای سنتز واکنشهای آلی، کاربردهای الکتروشیمیایی، آنتی اکسیدانت در روغن های روان کننده و در ابر خازنها کاربرد دارند. این خواص جالب با انتخاب کاتیون و آنیون مناسب بوجود می آید. از این رو بسیاری از خواص و کاربردهای آ...

Because of high toxicity of hydrazine and its derivatives, many efforts are conducted to finding alternative for hydrazine in hypergolic fuels which meanwhile can do spontaneous ignition, has a low environment risk. Due to high reducing ability of hydrazine, usage of powerful conducing agents’ idea was interested. These conducting agents required to improvement in order to use as a hyperg...

Room-temperature ionic liquids are a class of non-molecular ionic solvents with low melting points. Their properties have the potential to be especially useful as stationary phases in gas-liquid chromatography (GLC). A series of common ionic liquids were evaluated as GLC stationary phases. It was found that many of these ionic liquids suffer from low thermal stability and possess unfavorable re...
