Permeability of gas mixtures in glassy polymers with and without plasticization [PDF]

open access: yesJournal of the Serbian Chemical Society, 2021
In this research, the solubility, permeability and diffusivity of gas mixtures through glassy polymers were comprehensively studied. The diffusivity of the components in the mixture was assumed to be a function of the concentration of all components in ...

Effects of microstructure characteristics on the transverse moisture diffusivity of unidirectional composite

open access: yesScience and Engineering of Composite Materials, 2023
To reveal the effects of the microstructure characteristics including fiber shape, void, fiber distribution pattern, and interphase on the transverse moisture diffusivities of unidirectional composites, the steady analysis method based on Fick’s law is ...

The effect of using polypropylene fibers on the durability and fire resistance of concrete

open access: yesFracture and Structural Integrity, 2021
In order to study the effect of polypropylene fibers on the durability of cementitious composites, several experimental tests have been carried out in the laboratory. The composite was tested with different volume fractions of polypropylene fibers (0.05%,

Thermodynamics And Concentration Fluctuations Of Liquid Al-Cu And Al-Zn Alloys

open access: yesArchives of Metallurgy and Materials, 2015
Thermodynamic properties of liquid Al-Cu and Al-Zn alloys are investigated using the free volume model. We also analyse local atomic arrangements and concentration fluctuations in both liquid binary alloys from the determination of the Warren-Cowley ...

Modelling of fission gas release in UO2 doped fuel using transuranus code

open access: yesActa Polytechnica CTU Proceedings, 2022
The expected benefits from Cr-doped fuel are improved retention of fission gases within the pellets due to its large grain size. To demonstrate this, several experiments have been carried out by Halden reactor and Studsvik.

Diffusion representations [PDF]

open access: yesApplied and Computational Harmonic Analysis, 2018
Diffusion Maps framework is a kernel based method for manifold learning and data analysis that defines diffusion similarities by imposing a Markovian process on the given dataset. Analysis by this process uncovers the intrinsic geometric structures in the data.

A numerical-statistical approach to determining the representative elementary volume (REV) of cement paste for measuring diffusivity

open access: yesMateriales de Construccion, 2010
Concrete diffusivity is a function of its microstructure on many scales, ranging from nanometres to millimetres. Multi-scale techniques are therefore needed to model this parameter.

Diffusion Properties of Garcinia Fruit Acids (Garcinia atroviridis)

open access: yesWalailak Journal of Science and Technology, 2011
The diffusion properties of garcinia fruit acids (Garcinia atroviridis) were investigated in a batch reactor. The influences of two variables were studied: material thickness and extraction temperature.
