DOI: 10.1016/j.mri.2018.09.023

Abstract: Applying the concept of effective relaxivity to characterize wettability is based on the configuration of fluid distributions in porous media. However, in mixed-wet porous media with intermediate-wet patches (homogeneous wetting region), effective surface relaxivity cannot… read more here.

Published in 2022 at "Physical review letters"

DOI: 10.1103/physrevlett.130.126204

Abstract: We demonstrate an unexpected decay-recovery behavior in the time-dependent ^{1}H NMR relaxation times of water confined within a hydrating porous material. Our observations are rationalized by considering the combined effects of decreasing material pore size… read more here.

Published in 2024 at "Journal of Wood Science"

DOI: 10.1186/s10086-023-02117-x

Abstract: To determine the surface relaxivity of pores plays a vital role in the application of time-domain nuclear magnetic resonance (TD-NMR) technology to porous structure characterization for wood. Currently, the surface relaxivity of pores is calibrated… read more here.
