A discussion is presented on the effect of porosity change on the thermal expansion coefficient of porous materials. It is shown that both drained and undrained thermal expansion coefficients normally increase with porosity increase. Consequently the reduction of the thermal expansion coefficient with the porosity increase, as obtained in the experimental(More)
In recent years, the synergistic effects of Au-based hybrids have generated enormous scientific interest. The hybrids of Au and Co are expected to exhibit attractive properties. In this paper, we report the successful fabrication of the nanohybrids between bulk-immiscible Au and Co with chain-like structures via a mild solution method. Elemental mapping,(More)
