Abstract: The research reported in this paper evaluates a novel bitumen modification through the use of different inorganic nanoparticles, such as nanozinc oxide, nanosilica, and nanotitanium dioxide. In order to improve the dispersion ...

Abstract: The vanadium redox flow battery (VRFB) is an attractive grid scale energy storage option, but high operating cost prevents widespread commercialization. One way of mitigating cost is to optimize system performance, which ...

Abstract: Maintaining proper membrane humidity is crucial to ensure optimal operation of a polymer electrolyte membrane fuel cell system. A membrane humidifier using the fuel cell exhaust gas to humidify ...

Abstract: A membrane-based humidifier that uses cooling water of a fuel cell system to humidify the inlet air is modeled and analyzed in this paper. This four-state lumped model is simple and yet ...

Abstract: Development of magnetism based nondestructive testing technology and the Microelectronic mechanical system require accurate computation of perturbed magnetic fields generated by mechanical stress. ...

Abstract: Battery energy storage systems (BESSs) have been integrated with wind turbines to mitigate wind intermittence and make wind power dispatchable as traditional power sources. This paper presents two phases of optimizations, ...

Abstract: Membrane electrolyte assembly (MEA) aging is a major concern for deployed proton exchange membrane (PEM) fuel cell stacks. Studies have shown that working conditions, such as the operating temperature, humidity, and open ...

Abstract: Wind energy is a clean and renewable source for electricity generation. To reduce the costs associated with wind power generation, development of a control methodology that maximizes the wind energy capture and mitigates ...

Abstract: One of the main issues with vanadium redox flow batteries (VRFBs) is that vanadium ions travel across the membrane during operation which leads to a concentration imbalance and capacity loss after longterm cycling. Precise ...

Abstract: The effects of various amounts of organic montmorillonite (OMt) on the morphology and physical properties of bitumen before and after ultraviolet (UV) aging were investigated. The microstructures of OMt modified bitumens ...
