DO GRAIN RESERVES NECESSARILY CONTRIBUTE TO PRICES STABILITY AND FOOD SECURITY IN SUDAN? AN ASSESSMENT


Selective Detection of Nitrogen-Containing Compound Gases

N-containing gaseous compounds, such as trimethylamine (TMA), triethylamine (TEA), ammonia (NH3), nitrogen monoxide (NO), and nitrogen dioxide (NO2) exude irritating odors and are harmful to the human respiratory system at high concentrations.In this study, we investigated the sensing responses of five sensor materials—Al-doped Right Grip ZnO

In-situ reactive synthesis of full dense Si2N2O by incorporating of Amourphous nanosized Si3N4;effect of MgO and Y2O3

Si2N2O is considered as a new great potential structural/functional candidate in place of Si3N4.The amorphous Si3N4 nanopowder was incorporated into silica sol by adding of MgO and Y2O3 drawers as sintering aid.Synthesized powders were heated by spark plasma sintering at a heating rate of 100 oC/min yielded fully dense compacts at 1550 and 1750 oC
