Percolation calorimetry

The effect of ergosterol, an important component of fungal plasma membranes, on the physical properties of dipalmitoylphosphatidylcholine multibilayers has been studied by H NMR and differential scanning calorimetry. Solid-state NMR has been used to study lateral diffusion within model cell membrane. Simulations of lateral diffusion on a sphere with varying numbers and sizes of immobile obstacles and different percolation properties were... 

A means of measuring plant cell culture activities in liquid media by unstirred batch calorimetry was demonstrated by Fontana et al. [47]. Cells were floated on liquid media supplemented with an inert, high density preparation of Percoll. Other additives could also be used to increase media density. Cells at the air-media interface were able to obtain adequate supplies of both O2 and nutrients for rapid metabolism without diffusion rate limitations.
