Joint Method

Recently, sintering joint using Ag-nanohas been attracting attention as a new joint method to replace the solder. However, the joint layer would contain a lot of voids after sintering processes. Since the voids affect mechanical property, the proper sintering conditions have to be selected in order to reduce these voids. In this research, the authors focus on the effect of pressure conditions at sintering process. Then, by creating FEM models including voids from cross section image of the joint layer and carrying out tensile analysis, the mechanical property of the joint layer has been acquired. Using this approach, the influence of pressure conditions on the mechanical properties is revealed.

Carbon Honeycomb

Carbon honeycomb has a nanoporous structure with good mechanical properties including strength. Here we investigate the adsorption and diffusion of hydrogen in carbon honeycomb via grand canonical Monte Carlo simulations and molecular dynamics simulations including strength. Based on the adsorption simulations, molecular dynamics simulations are employed to study the effect of pressure and temperature for the adsorption and diffusion of hydrogen. To study the effect of pressure, we select the 0.1, 1, 5, 10, 15, and 20 bars. Meanwhile, we have studied the hydrogen storage capacities of the carbon honeycomb at 77 K, 153 K, 193 K, 253 K and 298 K. A high hydrogen adsorption of 4.36 wt.% is achieved at 77 K and 20 bars. The excellent mechanical properties of carbon honeycomb and its unique three-dimensional honeycomb microporous structure provide a strong guarantee for its application in practical engineering fields.
