Porous metallic material has become a kind of typical multifunctional material with the quick development of advanced manufacturing and forming process technologies in past years. At present, it has also been a structural function material with the characteristics of ultra-light weight, high specific strength and rigidity. As a sound absorbing material in noise control engineering, the acoustic...

Using starch as the carbon precursor and different-sized ZnO naoparticles as the hard template, a series of porous carbon materials for electrochemical sensing were prepared. Experiments of scanning electron microscopy, transmission electron microscopy and Nitrogen adsorption-desorption isotherms reveal that the particle size of ZnO has big impacts on the porous morphology and surface area of t...

Keywords: Solar energy Solar fuels Heat and mass transfer Porous media Computed tomography Morphology a b s t r a c t The performance of high-temperature solar reactors incorporating porous ceramic materials that serve as radiative absorbers and chemical reaction sites can be improved significantly by tailoring their pore structure. We investigated the changes in their effective heat and mass t...

To reduce the noise and vibration perturbations, it is beneficial to use the dissipative properties of poroelastic materials. These materials are generally not used alone, but rather inserted in composite mechanical assemblies made of elastic structures, poroelastic materials and air insertions. If these structures are assemblies of layers of materials, they are called multilayer complexes. If ...

Typically, the elastic and electrical properties of composite materials are strongly microstruc-ture dependent. So it comes as a nice surprise to come across exact formulae for eeective moduli that are universally valid no matter what the microstructure. Such exact formulae provide useful benchmarks for testing numerical and actual experimental data, and for evaluating the merit of various appr...

Porous organic cage stabilised palladium nanoparticles were successfully prepared using methanol as a mild reductant. The as-prepared porous composite materials show high catalytic activity for the carbonylation reaction of aryl halides under mild conditions.

Thermodynamic equations are de®eloped for adsorption of multicomponent gas mixtures in microporous adsorbents based on the principles of solution thermodynamics. The con®entional spreading pressure and surface area ®ariables, which describe 2-D films, must be abandoned for adsorption in micropores, in which spreading pressure cannot be measured experimentally or calculated from intermolecular f...
