Microwave-activated synthesis is a special and remarkable technique in modern synthetic organic chemistry. In the current research, it described microwave-assisted of 2-aryl-4,5-dicarbonitrile imidazole derivatives via one-step reaction between aromatic aldehydes 2,3-diaminomaleonitrile (DAMN) using HNO3 as metal-free catalyst strong oxidizing agent. The present methodology has significant adva...

Skyrocketing prices of fuel and increasing concerns towards achieving lower carbon footprints favor any improvements a greener transportation ecosystem. In this work we focus on missed approaches, which are forced maneuvers at the end regular flights that generate significant noise pollution levels near airports. previous introduced reinjection technique for maneuver able to substantially mitig...
