Abstract: An atomization generator and a special high-pressure atomization generation device for increasing oil and gas field recovery are provided. The special high-pressure atomization generation device for increasing oil and gas field recovery includes an agent pot assembly, a gear pump, a metering pump, an atomization generator and pipelines. The gear pump is connected with the agent pot assembly through an agent pot liquid inlet pipe. The metering pump is arranged between the agent pot assembly and the atomization generator which are connected through the low-pressure manifold pipeline and the high-pressure liquid inlet pipeline. The high-pressure liquid inlet pipeline is connected with the liquid inlet pipe. The liquid inlet pipes are connected with the metering pump. The gas inlet pipe is connected with the high-pressure gas source through the high-pressure gas inlet pipe. The gas inlet cap is provided with a gas inlet pipe.

Abstract: Provided are metalloorganic and organic compounds comprising a multicyclic system wherein a central nitrogen atom is part of two 5-membered rings which are fused together, and which are further fused together with three 6-membered aromatic rings. Also provided are formulations comprising these compounds. Further provided are organic light emitting devices (OLEDs) and related consumer products that utilize these compounds and compositions.
