    Rational Design of MoS2 C3N4 Hybrid Aerogel with

    Nov 12, 2020Constructing graphene-based heterostructures with large interfacial area is an efficient approach to enhance the electrochemical performance of supercapacitors but remains great challenges in their synthesis. Herein, a novel ultra-small amorphous Fe2O3 nanodots/graphene heterostructure (a-Fe2O3 NDs/RGO) aerogel was facilely synthesized via excessive metal-ion-induced self-assembly …

    Role of Temperature Sensor in Syngas WIKA blog

    Jan 26, 2017The sensor works by measuring the temperature that's being given off by the thermostat and/or the coolant itself. The temperature is then sent to the on-board control system. From there, your vehicle's computer will use this temperature information to either continue operating or adjust certain engine functions, always working to keep the engine temperature at an ideal level.

    Check The Material of The Wetted PartsBe Aware of False High ReadingsProcess Analyzers Are only as Good as The Sampling SystemEnsure The Vent Lines Out of The Analyzer Are ClearIt's far too often manufactures of H2S analyzers use wetted parts in their analyzers that readily absorb H2S. When H2S is absorbed into parts materials, a phenomenon called "in-gassing" will occur. In-gassing results when H2S is absorbed in materials before it reaches the detector. This results in lower H2S readings than what is actually in the sample. Ensure the wetted part materials is inert such as 316L stainless steel or PTFE (Teflon).
