Application of IR Thermography for Studying Deformation and Fracture of Paper

Field-cycling NMR relaxometry with spatial selection.

Fast field-cycling MRI offers access to sources of endogenous information not available from conventional fixed-field imagers. One example is the T(1) dispersion curve: a plot of T(1) versus field strength. We present a pulse sequence that combines saturation-recovery/inversion-recovery T(1) determination with field cycling and point-resolved spectroscopy localization, enabling the measurement ...

IR Thermography Applied to the Cultural Heritage Conservation

Extended Abstract Thermal non-destructive testing is more and more applied even in the field of cultural heritage conservation. The main reason is the capability of inspecting large surfaces without any contact or damage. A large number of testing procedures and processing algorithms allows reaching reliable results both in laboratory or in situ. Well established or innovative techniques are ba...

Compact NMR relaxometry of human blood and blood components

Nuclear magnetic resonance relaxometry is a uniquely practical and versatile implementation of NMR technology. Because it does not depend on chemical shift resolution, it can be performed using low-field compact instruments deployed in atypical settings. Early relaxometry studies of human blood were focused on developing a diagnostic test for cancer. Those efforts were misplaced, as the measure...

Measurement and Visualization of Tight Rock Exposed to CO2 Using NMR Relaxometry and MRI

Understanding mechanisms of oil mobilization of tight matrix during CO2 injection is crucial for CO2 enhanced oil recovery (EOR) and sequestration engineering design. In this study exposure behavior between CO2 and tight rock of the Ordos Basin has been studied experimentally by using nuclear magnetic resonance transverse relaxation time (NMR T2) spectrum and magnetic resonance imaging (MRI) un...
