Low cost and reliable sodium-metal halide (Na-MH) batteries for stationary energy storage application

Li G., Pacific Northwest National laboratory, US

Stationary electric energy storage devices have gained increasing prominence due to great market needs, such as smoothing availability of renewable energy resources and supporting the reliability of the electric grid. Among various battery technologies, with [...]

Synthesis By Two-step Growth Scheme For Fabrication of Hierarchical Micro/Nano-structured Mesoporous FePO4 Particles for High Performance Lithium-Ion Batteries

Dong B., Li G., Yang X., University of Nottingham Ningbo China, CN

Olivine lithium iron phosphate (LiFePO4) has been considered as a promising cathode material in fabrication of lithium ion battery because of its features of low cost, lower toxicity, higher stability, excellent capacity retention, extremely flat [...]

Synthesis and Self-Assembly of Biodegradable Poly(ethylene oxide)-b-Polycaprolactone (PEO-b-PCL) Diblock Copolymers

Li G., Ghoroghchian P., Qi W., Christian N., Frail P.R., Hammer D.A., Therien M.J., Carestream Health Inc., US

A series of amphiphilic poly(ethylene oxide)-b-polycaprolactone (PEO-b-PCL) diblock copolymers with various PEO blocks (number-average molecular weight (Mn): 750~5800), PEO weight fraction (fPEO) from 7.7% to 33.3%, and Mn of the copolymers from 3.6k to 57k, [...]

Finite Temperature Quasicontinuum Method for Thermal and Mechanical Analysis of Silicon Nanostructures

Tang Z., Zhao H., Li G., Aluru N.R., University of Illinois at Urbana-Champaign, US

We formulate a finite temperature quasicontinuum method to calculate the thermodynamic and elastic properties of crystalline silicon as well as the mechanical response of silicon nanostructures subjected to externally applied forces. We solve the continuum [...]

A Coarse-Grained Tight Binding Method for Electrostatic Analysis of Nanoelectromechanical Systems (NEMS)

Xu Y., Li G., Aluru N.R., Beckman Institute for Advanced Science and Technology, US

Silicon electrostatic nanoelectromechanical systems (NEMS) are one of the emerging applications in nanotechnology. As the critical length of a NEM structure shrinks to less than a few nanometers, classical models based on continuum approximations become [...]

Dynamic Analysis of Electrostatic MEMS by Meshless Methods

Li G., Aluru N.R., University of Illinois at Urbana-Champaign, US

Electrostatically actuated microstructures are widely used in microelectromechanical systems (MEMS). Computational analysis of electrostatic MEMS requires a self-consistent solution of the interior elastic domain and the exterior electrostatic domain. This paper proposes an efficient approach [...]

Design and Simulation of A Novel Highly Symmetrical Piezoelectric Triaxial Accelerometer

Li G., Li T., Li Z., Li G., Li T., Li Z., Wang C., Hao Y., Li G., Li T., Li Z., Wu G., Peking University, CN

A monolithic piezoelectric triaxial accelerometer, using a highly symmetric quad-beam structure with a single seismic mass, has been developed. The structure of the accelerometer is analyzed in detail theoretically and numerically. Static and modal simulations [...]

SEGS: On-line WWW Etch Simulator

Li G., Hubbard T., Antonsson E.K., Daltech-Dalhousie University, CA

This paper presents an interactive on-line wet etch simulator (SEGS) which predicts the etched shape as a function of time for arbitrary isotropic or anisotropic etchants and any initial mask shape. Using any Javaenabled web [...]
