Effect of Pore Shape on Mechanical Properties of Porous Shape Memory Alloy.

Porous shape memory alloys (SMAs) have been widely used in the aerospace, military, medical, and health fields due to its unique mechanical properties such as superelasticity, biocompatibility, and shape memory effect. In this work, the pore shape was considered in the constitutive model of the porous SMAs by respectively introducing the parameter of aspect ratio and for different pore shapes including oblate, sphere, and prolate shapes, so the expression of Young's modulus for the porous SMA can be derived. Then, the constitutive model for such a porous shape memory alloy was established.

Utilization of calcium-based and aluminum-based materials for the treatment of stabilized landfill leachate: a comparative study.

This study explored the efficiencies and mechanisms of refractory organic matters removal in the stabilized landfill leachate by adding different reagents. Calcium-based and aluminum-based materials were added into the leachate as comparing experiments. XRD, FTIR, and EEM were adopted to analyze the solid products and leachate.
