Parameter screening of a VPSA cycle with automated breakthrough control for carbon capture
(Elsevier, 2023-05-01)
Vacuum pressure swing adsorption (VPSA) is an efficient technology that can be used for carbon capture from combustion stationary sources. However, VPSA is a cyclic and complex process that involves ...
Shear wave cardiovascular MR elastography using intrinsic cardiac motion for transducer-free non-invasive evaluation of myocardial shear wave velocity
(Nature Research, 2021-01)
Changes in myocardial stiffness may represent a valuable biomarker for early tissue injury or adverse remodeling. In this study, we developed and validated a novel transducer-free magnetic resonance ...
