This study presents the first known detection of fission products commonly found in post-detonation nuclear debris samples using solid sample introduction and a uniquely coupled gas chromatography inductively-coupled plasma time-of-flight mass spectrometer. Rare earth oxides were chemically altered to incorporate a ligand that enhances the volatility of the samples. These samples were injected ...

results the modeling results showed that for the gas recovery starting in 2000 and 2015, the power generation would be 2,354 and 830 mw, respectively. in fact, the 15-year difference in gas extraction made a 200% difference. based on the results, from 2000 to 2100, 558 m3/hour of methane would be extracted, which would be equivalent to 2,354 mw energy. subsequently, the emission of 93,721,837 t...

This paper describes new sample cells and techniques for in situ powder X-ray diffraction specifically designed for gas absorption studies up to ca 300 bar (1 bar = 100 000 Pa) gas pressure. The cells are for multipurpose use, in particular the study of solid-gas reactions in dosing or flow mode, but can also handle samples involved in solid-liquid-gas studies. The sample can be loaded into a s...

In this work we propose an effective viscosity criterion for the stabilization of annular gas-liquid and liquid-particle flows and an inertial mechanism which drives waves into slugs in slugging gas-liquid flows. Annular flow is stable when the fluid having the higher effective viscosity occupies the core region and the lower viscosity fluid is the annulus. The eddy viscosity criterion is shown...

Received Apr 30, 2017 Revised Sep 27, 2017 Accepted Oct 11, 2017 This paper describes tests results on the CF3I-CO2 gas mixtures as an alternative for SF6 gas as to be used as insulating medium in high voltage applications. Pressurized CF3I-CO2 gas mixtures are subject under standard lightning impulse voltages at both positive and negative polarities. Under rod-plane configuration, the electrod...

The Cryogenic Carbon CaptureTM (CCC) process is a retrofit, post-combustion technology that desublimates CO2 in the flue gas, separates the resulting solid from the remaining light gases, pressurizes the solid CO2, melts the CO2 and warms the light gas, and completes the CO2 pressurization with liquid CO2. This skid-scale CCC system has demonstrated successful carbon capture of 90–99% from simu...

This paper deals with the interface between a solid and an ideal gas. The surface of the solid is considered to be an ideal wall, if the flux of entropy is continuous, i.e. if the interaction between wall and gas is non-dissipative. The concept of an ideal wall is discussed within the framework of kinetic theory. In particular it is shown that a non-dissipative wall must be adiabatic and does n...

Inverse gas chromatography (IGC) represents a unique reRnement of a classic chromatographic method in which an unknown solid material such as a powder, Rbre or Rlm may be characterized. By reversing the traditional role of unknown mobile phases and known reference stationary phases, the gas}solid chromatographic retention processes may be used to characterize an unknown particulate sample by el...

We present ISO SWS (AOT6) observations of the protostellar object RAFGL 7009S. This source is particularly interesting for the characterisation of chemistry arising from grain surfaces andmantles, since the solid state features ofmany simple molecules such asH2O,CO,CO2, CO2 andCH4 are detected, together with weaker features not yet unambiguously identified. Gas phase H2O, CO2, CH4 and CO can al...
