Special Issue in Materials: Advances in Functional Cellular Structures and Composites
Porosity in ceramic materials is be one of the key features for a wide range of applications. They are used as lightweight structures, filters, acoustic or heat insulation, scaffolds and support structures for catalysis applications. Besides the low relative density, high temperature, as well local failure resistance, pore interconnectivity and permeability are interesting properties of porous ceramics. As example, they can be used as exhaust diesel filters or catalyst support structure in the automotive industry, as well as for filter or purification systems in the chemical and metal-processing industry, in waste-water treatment, biotechnology, pharmaceutical and food technology. In addition, various porous ceramics, such as cellular lightweight structures, can be used as thermal and acoustic insulators, ceramic heaters and heat exchangers. Porous ceramics show outstanding structural (open/closed pores, cell/pore shape) and physical (mechanical, thermal, electric and acoustic) properties depending on porosity, pore network, pore connectivity and pore shape depending on the fabrication process. With additive manufacturing of more complex structures with designed properties and macrostructure can be made. Adding additional functionalization enhances mechanical, thermal or catalytic properties of homogeneous and non-homogeneous materials. Functionalization can be done by additional active or non-active surface coatings, chemical reactions on the surface, increasing surface area by introduction of hierarchy or solid-state reactions between coating and support.
This functional and structural enhancement can lead to a wide variation of porous ceramic materials covering an extensive range of structural and physical properties.
This Special Issue aims to cover research of relevance to novel processing techniques in particular on functionalization of physical and structural properties of porous and cellular ceramics. Focus will be processing on characterisation and testing setup for physical and structural properties, simulation and optimization methods.
The scopes of this Special Issue include, without being limited to, the following themes: Processing methods and technologies, functionalization, hierarchical porosity, the influence of porosity on various properties, pore forming mechanisms, microstructure evaluation, physical and structural characterisation and testing, optimization (including calculations) of properties and processes, simulation of properties over length-scales, and applications of porous ceramics.
