The impact of temperature variations of the injected CO2 on the mechanical integrity of a reservoir is an important problem but rarely addressed in the design of a CO2 storage site. In this study, a three-dimensional (3D) thermo-geomechanical approac

A commercial SCR filter, deployed in the USA in 2015, was sectioned and examined using techniques including mercury porosimetry, electron microscopy, and micro-X-ray computed tomography. The catalyst washcoat was found to be consistent with Cu/SSZ-13

To study the discharge performance of Li–O2 batteries, we propose a multiscale modeling framework that links models in an upscaling fashion from the nanoscale to mesoscale and finally to the device scale. We have effectively reconstructed the micro

Gasoline Compression Ignition (GCI) engines have the potential to achieve high fuel efficiency and to significantly reduce both NOx and particulate matter (PM) emissions by operating under dilute, partially-premixed conditions. This low temperature c
