Three-dimensional scaffolds for tissue engineering applications: role of porosity and pore size.
Tissue engineering. Part B, Reviews, 2013 Tissue engineering applications commonly encompass the use of three-dimensional (3D) scaffolds to provide a suitable microenvironment for the incorporation of cells or growth factors to regenerate damaged tissues or organs. These scaffolds serve to mimic

Machine learning-based porosity estimation from spectral decomposed seismic data [PDF]
arXiv, 2021 Estimating porosity models via seismic data is challenging due to the signal noise and insufficient resolution of seismic data. Although impedance inversion is often used by combining with well logs, several hurdles remain to retrieve sub-seismic scale porosity.

Threedimensional Local Porosity Analysis of Porous Media [PDF]
, 1998 A quantitative comparison of the pore space geometry for three natural sandstones is presented. The comparison is based on local porosity theory which provides a geometric characterization of stochastic microstructures. The characterization focusses on porosity and connectivity fluctuations.
