Solvent pulping at atmospheric pressure.

Plasma-Assisted Deposition at Atmospheric Pressure

In plasma-assisted deposition methods the activation energy necessary for the initiation of chemical reactions is transferred via charged particles. Due to this fact in many cases the process temperature can be kept small, if gas discharges at pressures below 1 hPa are used. On the other hand low pressure requires a great deal of vacuum equipment. Processes at atmospheric pressure are more favo...

Transmission Electron Microscopy at Atmospheric Pressure

The ability to monitor dynamic processes in-situ is crucial for understanding structure-property relationships in nano-engineered materials. In the past decade, the majority of atomic-scale electron microscopy studies involving gas-solid interactions were conducted in an environmental transmission electron microscope (ETEM), where the gas pressure is typically limited to no more than 1/100 of a...

Two Phase Heat Transfer Characteristics in a Vertical Small Diameter Tube at Sub Atmospheric Pressure

Two-phase heat transfer is experimentally examined through vertical small diameter tubes, D =1.45 and 2.8 mm using water under a pressure of 50 to 81 kPa and a natural circulation condition. The pool boiling correlation by Stephan-Abdelsalam and the thermosyphon boiling correlation by Imura, et al. predict the measured experimental data in the 2.8 mm tube with an error of -30%. A large heat tra...
