Separators with high reliability and security are in urgent demand for the advancement of high performance lithium ion batteries. Here, we present a new and practical porous membrane with three-dimension (3D) heat-resistant skeleton and high curvature pore structure as a promising separator candidate to facilitate advances in battery safety and performances beyond those obtained from the conven...

Abstract In order to realize tritium self-sufficiency during the operation of fusion reactors, neutron multiplier materials are needed multiply number neutrons. Beryllium (Be) and beryllides (Be 12 V, Be Ti) considered as candidates for in breeding blanket. Thermal performances essential data evaluate service performance future reactors. Due toxicity beryllium, preparation analysis challenging....

Perovskite CH3NH3PbI3 exhibits outstanding photovoltaic performances, but the understanding of the atomic motions remains inadequate even though they take a fundamental role in transport properties. Here, we present a complete atomic dynamic picture consisting of molecular jumping rotational modes and phonons, which is established by carrying out high-resolution time-of-flight quasi-elastic and...

This paper studies different IGCC systems with CO2 recovery. In order to effectively reduce CO2 emissions from the IGCC system, several kinds of IGCC systems with quasizero CO2 emissions have been studied in this paper. The key parameters affecting the IGCC systems’ performance have been analyzed and compared. The systems’ performances have been investigated based on comparison of different IGC...

The present paper will approach the design and analysis of a permanent magnet synchronous motor (PMSM) for automotive electromechanical braking (EMB) system. Due to technological and cost constraints, for the PMSM prototype a slightly different topology of the rotor is proposed. Finite element method will be used for analyzing the static performances of the former topology, and compare them wit...

The classical asphalt mix manufacturing commonly requires the heating and the complete drying of aggregates. The induced energy cost has opened the way to develop alternatives processes with low energy/ carbon materials such as Warm Mix Asphalt (WMA). Their manufacturing requires specifics techniques to achieve similar performances than Hot Mix Asphalt (HMA). However, manufacturing temperature ...

We combined soft x-ray reflectivity and x-ray standing wave enhanced fluorescence to study the optical performance and the thermal induced interface behaviour of Co/Mo2C nanometric multilayers, designed to work in the soft x-ray range close to the Co L3 absorption edge. Grazing x-ray reflectivity measurements were performed at 0.154 nm (Cu Kα line) and at two wavelengths in the soft x-ray range...
