Scaling analyses for hyperpolarization transfer across a spin-diffusion barrier and into bulk solid media

David Lyndon Emsley, Arthur César Pinon, Bradley Floyd Chmelka

By analogy to heat and mass transfer film theory, a general approach is introduced for determining hyperpolarization transfer rates between dilute electron spins and a surrounding nuclear ensemble. These analyses provide new quantitative relationships for ...

Measurement of Proton Spin Diffusivity in Hydrated Cementitious Solids

David Lyndon Emsley, Brennan James Walder, Federico Maria Paruzzo, Jayasubba Reddy Yarava, Bradley Floyd Chmelka

The study of hydration and crystallization processes involving inorganic oxides is often complicated by poor long-range order and the formation of heterogeneous domains or surface layers. In solid-state NMR, H-1-H-1 spin diffusion analyses can provide info ...
