Microstructural characterization of a Canadian oil sand [PDF]
, 2012 The microstructure of oil sand samples extracted at a depth of 75 m from the estuarine Middle McMurray formation (Alberta, Canada) has been investigated by using high resolution 3D X-Ray microtomography ($\mu$CT) and Cryo Scanning Electron Microscopy ...

Cryomagma ascent on Europa [PDF]
, 2019 Europa's surface exhibits morphological features which, associated with a low crater density, might be interpreted to have formed as a result of recent cryovolcanic activity. In particular, the morphology of smooth deposits covering parts of the surface,

Influence of liquid-nitrogen freezing of gas-bearing shale rocks on their compressive strength [PDF]
, 2018 Any definable relation between falling temperature and the compressive strength of shale rocks should provide a useful predictive tool aiding optimization of the results of hydraulic fracturing.

The Bacterial Nucleoid: From Electron Microscopy to Polymer Physics—A Personal Recollection
Life, 2023 In the 1960s, electron microscopy did not provide a clear answer regarding the compact or dispersed organization of the bacterial nucleoid. This was due to the necessary preparation steps of fixation and dehydration (for embedding) and freezing (for ...
