Electron field emission from room temperature grown carbon nanofibres
The observation of electron emission from room temperature deposited carbon nanofibres at low applied electric fields (~5 V/m) is reported. The nanofibres were grown using methane as a source gas in conventional plasma enhanced chemical vapor deposition reactor over a Ni catalyst at room temperature. Scanning electron microscopy images of the nanofibres show them to possess an average diameter...
متن کاملRoom temperature synthesis of biodiesel using sulfonated graphitic carbon nitride
Sulfonation of graphitic carbon nitride (g-CN) affords a polar and strongly acidic catalyst, Sg-CN, which displays unprecedented reactivity and selectivity in biodiesel synthesis and esterification reactions at room temperature.
متن کاملBi(NO3)3.5H2O: An efficient acidic reagent for synthesis of azo dyes at room temperature
An one-pot method has been developed for the synthesis of azo dyes via sequential diazotization–diazo coupling of aromatic amines with coupling agents at room temperature in the presence of Bi(NO3)3. 5H2O. Short reaction times, high yields, a clean process, simple methodology, easy work-up and green conditions are advantages of this protocol.
متن کاملTetrabutylammonium bromide-Cesium carbonate: new reagent system for the synthesis of substituted pyridines at room temperature
The highly substituted pyridine derivatives are found to exhibit diverse pharmacological activities. They are also emerged as potential medicinal leads in developing therapeutic agents for the treatment of various diseases. In this work, a series of 2-amino-3,5-dicarbonitrile-6-thio-pyridine derivatives have been synthesized at room temperature via one-pot, multi-component reaction of various a...
متن کاملEfficient and eco-friendly synthesis of quinoxalines derivatives catalyzed by acidic ionic liquids at room temperature
In this research, we have developed cheap recyclable and task-specific acidic ionic liquids (AILs) 1-hydrogen-3-methylimidazolium hydrogen sulfate [Hmim]HSO4, 1-hydrogen-3-methylimidazolium chloride [Hmim]Cl, 2-pyrrolidonium hydrogensulfate [Hnhp]HSO4 and applied them in acid catalyzed synthesis of quinoxaline derivatives from 1,2-phenylendiamines and 1,2-dicarbonyl compounds. The products coul...
