Project Description: 

Atomistic simulation enables to understand the mechanism of the bending behavior of bilayered Ni comprising a nanohoneycomb Ni layer on top of a solid Ni layer upon electric loading.

Research Project Details
Project Duration: 
09/2014 to 08/2018
Project Significance: 
Nanohoneycomb structures have lage effective surface area and ordered porous pattern. Experiments indicate that charging can induce reversible straining in nickel with a regular nanoporous honeycomb structure, which makes the material a promising electrochemical actuator.
Results Achieved: 
Charges accumulate on the surface of metal when immersing in water.
Remarks: 
Large scale simulations require HPC to reduce time as well as to increase the model scale.
