Mass transport of solvents into immiscible blends may exhibit a non‐Fickian behavior due to the deformation of the embedded interface that couples with diffusion. We introduce an interface area covariant tensor N as a structural state variable and derive a set of thermodynamically‐consistent PDEs and ODEs transport equations for the bulk and time‐dependent boundaries. The proposed model, which is...
In this work, we study the influence of various technological factors on silicon solar cells efficiency. We use simulation by personal computer one dimension software package (PC1D) solving equations describing the transport of electrons and holes in devices based on semiconductor materials. We highlight the most critical steps and the technological factors to be improved to increase solar cells efficiency...
A conical resonator using the acoustic near-field technique has been designed and developed. The characterization of liquid media by this resonator permitted to relate the electrical measurement parameters Δf and Δ(1/Z) to the density and viscosity of the analyzed solutions. The study of the changes of the resonance features of the resonator permitted the characterization, without discontinuity, of...
