Non-uniform assignment method for skeletal materials based on slope difference distribution and experimental validation.

A modeling method of non-uniform material assignment based on Slope Difference Distribution (SDD) is proposed to establish a complete and effective finite element (FE) model of the lower limb tibia. The validity and accuracy of the model based on in vitro mechanical experiments are verified. An initial tibia model was established based on Computed Tomography (CT) images.

Mechanism Exploration of Ion Transport in Nanocomposite Cation Exchange Membranes.

The origin of property enhancement of nanocomposite ion exchange membranes (IEMs) is far from being fully understood. By combining experimental work and computational modeling analysis, we could determine the influence of nanomaterials on the ion transport properties of nanocomposite cation exchange membranes (CEMs). We synthesized and characterized a series of nanocomposite CEMs by using SPPO as polymer materials and silica nanoparticles (NPs) (unsulfonated or sulfonated) as nanomaterials.

Enhanced Ionic Conductivity and Power Generation Using Ion-Exchange Resin Beads in a Reverse-Electrodialysis Stack.

Reverse electrodialysis (RED) is a promising technique for harvesting energy by mixing seawater with river water. The energy production is usually limited by ionic conductivity in dilute compartments of a RED system. Novel tests were conducted in this research, which used ion-exchange resin beads (IERB) to replace nonconductive spacer fabrics in RED compartments with dilute NaCl solution in a modified stack containing Fumasep FKS and Fumasep FAS membranes.
