Introduction and Discussion Efforts towards understanding the size-structure-property correlations for nanoscale systems have gained considerable importance in the recent years.
For assuring the functional reliability of alloys constituting bulk immiscible atoms it is extremely necessary to investigate whether the as-synthesized solid solution structures is a kinetically frozen atomic arrangement or a thermodynamically stable structure.
Chemically synthesized Ag-Co nanoparticles with an as-synthesized solid solution structure were annealed inside a transmission electron microscope.
Note that in bulk, Ag–Co system shows no mutual solubility into a single phase solid solution structure up to a very high temperature [28].

Results and Discussion In the experiment, the structures of sample are investigated by X-ray diffraction (XRD) and Raman spectroscopy.
Fig. 2d is a typical TEM image which showed that the porous structure contains some pores 10-20 nm in diameter in the red circle.
Therefore, this porous structure of CoS2 exhibited excellent electrocatalytic performance.
Through the experimental process and results, we analyzed the main process of formation of CoS2 porous structure.

The chemistry process may expand the volume of the concrete building and produce the local concentrated stress.
The expansion may get strong with time and change the uniform previous structure of concrete to result in the deformation, expansion and destroy of the building( M.D.A.
At the second stage, the amount of expansion materials generate great expansion stress, destroy the pore structure and expand the small cracks.
