Elastic electron scattering from 3-hydroxytetrahydrofuran: experimental and theoretical studies

We report the results of measurements and calculations for elastic electron scattering from 3-hydroxytetrahydrofuran (C4H8O2). The measurements are performed with a crossed electron-target beam apparatus and the absolute cross-sections are determined using the relative flow technique. The calculations are carried out using the Schwinger multichannel method in the static-exchange plus polarizati...

Experimental and Numerical Model Studies of Frictional Instability Seismic Sources

Stick-slip frictional instability is widely regarded as a viable mechanism for crustal earthquakes, particularly because of the way that it can be incorporated into the notion of earthquakes as episodic unstable slip events along preexisting zones or planes of weakness represented by faults in the Earth. In this thesis, detailed laboratory observations of stick-slip events generated on a simula...

Experimental Studies of CO2 Capturing from the Flue Gases

CO2 emissions from combustion flue gases have turned into a major factor in global warming. Post-combustion carbon capture (PCC) from industrial utility flue gases by reactive absorption can substantially reduce the emissions of the greenhouse gas CO2. To test a new solvent (AIT600) for this purpose, a small pilot plant was used. This paper presents the results of studies ...

Geologic Applications of Seismic Scattering

Once disregarded as noise, scattered seismic waves are finding increasing application in subsurface imaging. This sea change is driven by the increasing density and quality of seismic recordings and advances in waveform modeling which, together, are allowing seismologists to exploit their unique properties. In addition to extensive application in the energy exploration industry, seismic scatter...
