Porosity, Differentiability and Pansu's Theorem
, 2016 We use porosity to study differentiability of Lipschitz maps on Carnot groups. Our first result states that directional derivatives of a Lipschitz function act linearly outside a $\sigma$-porous set.

Maillard Type Reaction for Electroless Copper Plating onto Ceramic Nanoparticles
Advanced Engineering Materials, EarlyView.This work presents the manufacturing of copper‐plated ceramic nanoparticles in an environmentally friendly way. Supported by organic functionalizations with pectin an electroless plating step can be performed. Sustainable reagents like xylose, and several amino acids are used for the reduction process.

Local Percolation Probabilities for a Natural Sandstone
, 1996 Local percolation probabilities are used to characterize the connectivity in porous and heterogeneous media. Together with local porosity distributions they allow to predict transport properties \cite{hil91d}.

Advanced Engineering Materials, EarlyView.Al–Si alloys are particularly in demand for automotive and electronic applications, thanks to their excellent wear and thermal properties. Nevertheless, when processed by conventional methods with low cooling rates, the coarse primary Si phases are responsible for increasing brittleness and inducing crack propagation.

Measurement of Paper Porosity [PDF]
Beiträge zur Tabakforschung International/Contributions to Tobacco Research, 1970 AbstractThe ''porosity'' or ''air permeability'' of cigarette tissue is measured by many different instruments, is expressed in various units and it is frequently impossible to correlate such measurements and the readings of such instruments. The property of a paper whereby it allows air and gases to pass through it while still containing the burning ...

Mechanisms of De‐icing by Surface Rayleigh and Plate Lamb Acoustic Waves
Advanced Engineering Materials, EarlyView.Ice accretion impacts daily life, renewable energy generation, maintenance, and security in industries and aeronautics. Acoustic waves (AW) are a promising method for ice removal, although de‐icing mechanisms require further investigation to optimize energy efficiency.

The effect of contact torques on porosity of cohesive powders
, 2004 The porosity of uniaxially compacted cohesive powders depends on the applied stress (including gravity). The case, where these stresses are weak, is considered.

POROSITY: VII. THE DETERMINATION OF THE POROSITY OF HIGHLY VITRIFIED BODIES43 [PDF]
Journal of the American Ceramic Society, 1922 ABSTRACT Design and Accuracy.—The accuracy limitations of the general laboratory research type of porosimeter are discussed and the principles of design indicated. McLeod‐Gauge Type of Porosimeter.—A new type of porosimeter is described with which the pore volume of any test piece may be directly determined within 0.01–0.02 cc.
