TL;DR: The effect of fiber addition on the distribution and mobility of protons in biscuits is studied by using low resolution time domain nuclear magnetic resonance (TD-NMR) to gain insight on the processes occurring in biscuit baking.

TL;DR: This study is the first quantitative validation of the effects of the mutual interactions between gas particles on the individual diffusion properties, and shows that the dependency of gas phase diffusion properties on the local chemical environment may not be neglected, e.g. in diffusion-controlled chemical reactions.

TL;DR: In this paper, the authors used double quantum nuclear magnetic resonance (DQ NMR) experiments to characterize the elasticity of model polymer networks prepared with cross-linkers of mixed functionality and control of structural defects.

TL;DR: In this paper, the adsorption of water vapor in mesoporous TiO2 was studied by nuclear magnetic resonance (NMR) and multiscale molecular dynamics simulations, and three different water environments were distinguished and quantified: a first layer, where strongly bound water molecules exist at the inner surfaces; a second less structured layer but still with restricted mobility; and a bulk-like fraction of mobile water.

TL;DR: The diffusion of alkaline chlorides (LiCl, KCl, and CsCl) and water in mesoporous silica samples with pore sizes covering the range from micropores (2 nm) up to mesopores larger than 30 nm have been measured by resorting to a simple diffusional technique in the case of electrolytes and 1H NMR as mentioned in this paper.
