Fractal Derivative Model for Air Permeability in Hierarchic Porous Media
Abstract and Applied Analysis, 2012 Air permeability in hierarchic porous media does not obey Fick's equation or its modification because fractal objects have well-defined geometric properties, which are discrete and discontinuous. We propose a theoretical model dealing with, for the first

Fast‐Responding O2 Gas Sensor Based on Luminescent Europium Metal‐Organic Frameworks (MOF‐76)
Advanced Functional Materials, EarlyView.Luminescent MOF‐76 materials based on Eu(III) and mixed Eu(III)/Y(III) show rapid and reversible changes in emission intensity in response to O2 with very short response times. The effect is based on triplet quenching of the linker ligands that act as photosensitizers. Average emission lifetimes of a few milliseconds turn out to be mostly unaffected by

The determination of air-permeability of soils.
Netherlands Journal of Agricultural Science, 1960 An improved apparatus for determining air-permeability of soils at constant pressure gradient is described; its merits are discussed in the light of existing literature. Some experimental results obtained with a sandy soil under different tillage conditions are given and discussed. (Abstract retrieved from CAB Abstracts by CABI’s permission)
