A series of NiCoB amorphous alloy catalysts were prepared by chemical reduction method in different single and mixed solvent systems and their performance for liquid phase hydrogenation of furfural (FUr) was evaluated. The catalysts were also characterized by N2 adsorption-desorption, ICP, FE-SEM, HrTEM, Xrd and XPS. The results showed that the surface tension, viscosity, polarity and solubility parameter of preparation solvent had important effects on the composition, morphology, structure and the catalytic properties of FUr hydrogenation of the NiCoB amorphous alloy catalyst. The NiCoB-MEG catalyst prepared by the mixed solvent of methanol/ethylene glycol (MEG, volume ratio of 1:1) showed the optimum liquid phase hydrogenation performance of FUr to furfuryl alcohol (FA) with a FUr conversion of 96.4% and a FA selectivity of 83.49%. It can be due to the improvement of dispersion and reduction of metallic components by the synergistic effect between methanol and ethylene glycol. © 2017, Science Press. All right reserved.

This paper presents the innovative design of an air cooled permanent magnet assisted synchronous reluctance machine (PMaSyrM) for automotive traction application. Key design features include low cost ferrite magnets in an optimized rotor geometry with high saliency ratio, low weight and sufficient mechanical strength as well as a tailored hairpin stator winding in order to meet the demands of an A-segment battery electric vehicle (BEV). Effective torque ripple reduction techniques are analyzed and a suitable combination is chosen to keep additional manufacturing measures as low as possible. Although the ferrite magnets exhibit low remanence, it is shown that their contribution to the electrical machine's performance is essential in the field weakening region. Efficiency optimized torque-speed-characteristics are identified, including additional losses of the inverter, showing an overall system efficiency of more than 94%. Lastly, the results of no load measurements of a prototype are compared to the FEM simulation results, indicating the proposed design of a PMaSyrM as a cost-effective alternative to state-of-the-art permanent magnet synchronous machines (PMSM) for vehicle traction purposes.

As one of the core cooling equipment in district cooling system, latest electric chiller can achieve high energy efficiency and low CO 2 emission. In recent years, many researches have been conducted on cooling plant performance evaluation and anomaly detection, but very few can quantitatively detect root causes of electric chiller's performance anomaly. In the case study at district cooling plant of UTP (Universiti Teknologi PETrONAS), we adapted rCA (root Cause Analysis) diagnosis method from steam absorption chiller to electric chiller; developed two bottleneck models for electric chiller's COP (Coefficient of Performance) and CHW (CHilled Water supply) performance diagnosis. By applying new rCA models and method to field trial at UTP campus cooling system, we effectively diagnosed the root cause for electric chillers' performance degradation during period from 2014 to 2015.

A Semi-Empirical Capacity Fade Model for Li-NCA Cathode

引用

ECS Meeting Abstracts 2016年第6期MA2016-02卷

作者： Suman Basu Krishnan S Hariharan Subramanyya Mayya Kolake Taewon Song SAIT-India Samsung R&D Institute India-Bangalore Samsung Research and Development Institute Energy Material Lab SAIT Samsung Electronics

Lithium Nickel-Cobalt-Aluminum (NCA) is a popular cathode material for Li-ion cells due to its high energy density and moderate cost. Cycling experiments confirmed that the cathode capacity fade is the dominant capacity fade mechanism [1] in such cells. Electron energy loss spectroscopy (EELS) and X-ray Absorption Fine Structure (XAFS) analysis of the aged LiNCA particles exhibit the formation of a NiO type layer, which is inactive to Li intercalation, at the surface of the particles. Estimated amount of this inactive layer is found to match with the capacity loss of the cell. Therefore, a physics based model with one empirically determined parameter has been constructed for this reaction and it has been implemented on Li-ion battery electrochemical model [3]. The model predicts the relative capacity of a Li-NCA cell cycles at different temperatures with high accuracy (Fig.1). For constant current condition, a simple closed form solution for the capacity fade has been derived and validated. On extension this model can effectively predict the remaining useful life. references: Y. Zhang and C-Y. Wang, J. Electrochem. Soc., 156, A527 (2009). T. Sasaki, T. nonaka, H. Oka, C. Okuda, Y.

When designing an Electromagnetic interference (EMI) filter for power electronic converters, we should consider the shielding performance against the external near field coupling to the EMI filter as well as the attenuation performance. In this paper, we studied the validity of the Finite Element Method (FEM) simulation of the EMI filter for predicting the shielding performance before a trial manufacture. First, we created models of capacitors and common mode choke coils which can simulate their impedance characteristics. Next, using these component models, the assembled EMI filter model was created. We compared the measured and simulated results to verify the model. The shielding performance was evaluated using a loop coil as an external near field source. Consequently, the simulated results agreed with the measured results well.
