Free volume theory explains the unusual behavior of viscosity in a non-confluent tissue during morphogenesis [PDF]
eLifeA recent experiment on zebrafish blastoderm morphogenesis showed that the viscosity (η) of a non-confluent embryonic tissue grows sharply until a critical cell packing fraction (ϕS).

Free‐Volume Regulation Enables Significantly Enhanced Electrical Breakdown via Short‐Chain Molecular Spatial‐Positioning Intercalation into Poly(vinylidene fluoride) [PDF]
Advanced ScienceThe peculiar molecule‐structural units with ferroelectric ordering render poly(vinylidene fluoride) (PVDF) a crucial functional polymer, but the existence of the free volume in PVDF (also for many other polymers) would interrupt the long‐range molecule ...

Free Volume in Membranes: Viscosity or Tension? [PDF]
Open Journal of Biophysics, 2015 Many papers have used fluorescent probe diffusion to infer membrane viscosity but the measurement is actually an assay of the free volume of the membrane. The free volume is also related to the membrane tension. Thus, changes in probe mobility refer equally well to changes in membrane tension.

Positron annihilation spectroscopy of chain-end-functionalized polystyrenes with definite numbers of benzyl alcohol and perfluorooctyl groups [PDF]
Polímeros, 2020 A series of well-defined chain-end-functionalized polystyrenes with a definite number of benzyl alcohol and perfluorooctyl groups [PS(BnOH)n & PS(BnORf)n, respectively] linearly aligned in a double line at the chain-ends were prepared and investigated ...

Notes on Free Volume Theories [PDF]
Polymer Journal, 1991 There are two typical formulations for the mobilities of jumping units in concentrated polymer solutions on the basis of free volume concept. One is due to Fujita and the other to Vrentas and Duda. The prevailing notion that the former is contained as a special case of the latter is not correct, because the two theories are built on significantly ...
