Solventless Fabrication of Porous-on-Porous Materials
ACS Applied Materials & Interfaces, 2013Here we fabricate patterned porous polymer membranes on porous substrates by a combination of physical masking and chemical vapor deposition. This all-dry technique eliminates solvent-related issues and allows for the fabrication of hierarchical porous-on-porous structures with a wide range of chemical compositions and shapes.

Magnetic Resonance Imaging, 1998
Nuclear magnetic resonance (NMR) was used to determine the pore size distribution of hardened Portland cement pastes. The method is based on the well-known freezing point depression of water when confined inside the pore matrix of a material. It is demonstrated how this technique can be applied in cementitious materials to probe the microstructure of ...

ON THERMOPIEZOELECTRICITY FOR POROUS MATERIALS
Journal of Thermal Stresses, 1993This article is concerned with some basic theorems in the theory of thermopiezoelectric materials with voids. We establish uniqueness and reciprocity relations both for quasi-static and dynamic theory. A minimum principle of Reiss and Haug type is presented in the context of the quasi-static theory.

Microanalysis of Porous Materials
Microscopy and Microanalysis, 2004A signal loss is generally reported in electron probe microanalysis (EPMA) of porous, highly divided materials like heterogeneous catalysts. The hypothesis generally proposed to explain this signal loss refers to porosity, roughness, energy losses at interfaces, or charging effects.

Pectin‐Derived Porous Materials
Chemistry – A European Journal, 2010AbstractPorous forms of pectin, a major industrial waste biomass polysaccharide, have been prepared by aqueous phase expansion routes (SBET>200 m2 g−1; Vpore>0.80 cm3 g−1). It was demonstrated that the aqueous phase acidity crucially influenced the properties of the porous pectin form.

Porous Materials for Water Purification
Angewandte Chemie, 2023AbstractWater pollution is a growing threat to humanity due to the pervasiveness of contaminants in water bodies. Significant efforts have been made to separate these hazardous components to purify polluted water through various methods. However, conventional remediation methods suffer from limitations such as low uptake capacity or selectivity, and ...

A porous material (medium) is a substance that contains pores (voids), or spaces, between solid materials through which liquid or gas can flow. Examples of naturally occurring porous media include sand, soil, and some types of stone. Sponges, ceramics, and reticulated foam are also manufactured for porous materials.

ENGINEERED POROUS CATALYTIC MATERIALS
Annual Review of Materials Research, 2005▪ Abstract In recent years substantial progress has been made in the control of the properties of porous materials on the nano-, meso-, and macroscale. The feature of solids can, in favorable cases, be tailored to such an extent that one is justified in using the term engineering of porous catalytic materials.
