Abstract Adsorption phenomena are encountered in several engineering applications. One of its uses is the storage and transport gas form adsorption tanks. The exothermic nature process decreases capacity presenting an impetus to understand thermal characteristics process. Studies using mixtures phase change materials adsorbents tanks demonstrate potential improvements They also show that distri...

Spatial variation of material structures is a principal mechanism for creating and controlling spatially varying material properties in nature and engineering. While the spatially varying homogenized properties can be represented by scalar and vector fields on the macroscopic scale, explicit microscopic structures of constituent phases are required to facilitate the visualization, analysis and ...

Graded porous inorganic materials directed by macromolecular self-assembly are expected to offer unique structural platforms relative to conventional porous inorganic materials. Their preparation to date remains a challenge, however, based on the sparsity of viable synthetic self-assembly pathways to control structural asymmetry. Here we demonstrate the fabrication of graded porous carbon, meta...

The maximum cooling temperature of a uniform thermoelectric material is limited by its dimensionless figure of merit ZT. Inhomogeneous or graded thermoelectric materials are mainly studied when there is a large temperature gradient and the material composition is typically optimized for maximum local ZT. We show that this is not the correct optimization for maximizing the cooling temperature. W...
