THE rapid growth of new energy vehicles is accelerating the low-carbon transition in the global transportation sector. According to the international energy agency report, more than 10 million electric vehicles(EVs) including pure electric and hybrid models were sold worldwide in 2022, which means that the global share of electric vehicles in the overall automotive market has risen from less than 5% in 2020 to 14% in 2022.

Transform of atmospheric dust particles is one of the key processes to modify the physical and chemical properties of dust particles during their travel in the atmosphere. To understand the transform, the original characteristics of dust particles at the source areas, i.e. the physical and chemical characteristics before the particles travel in the air are essential. Although there have been a number of studies on dust particles at Chinese desert areas, the understandings are still the collections of some case studies. To get a more comprehensive understanding on the dust particles before floating in the air, we developed a chamber and used it to float and collect dust samples from surface soils at Tengger desert. Then the particles were analysed by using a scanning electron microscope and its attached energy dispersive X-ray spectrometer. The shape, size, and elemental composition were obtained. Based on these information, we compared the prepared dust with the results on dust particles reported by previous studies at the desert areas. Results showed very good consistence with the expected, and further revealed the details of dust particles in the size range of smaller than 1?m, on which only a limited amount of data are available. Similar sample preparation and particle analysis will be carried out for the surface soils in various desert areas, in order to obtain the general figures of dust particles before their travel in the atmosphere.

Journal of Modern Power Systems and Clean Energy 2017年第3期5卷 299-313页

The growing installation of natural gas fired power plants has increased the integration of natural gas and electricity sectors. This has driven the need investigate the interactions among them and to optimize energy resources management from a centralized planning perspective. Thus, a combined modeling of the reservoirs involved in electric power and gas systems and their locations on both networks are essential features to be considered in the operational planning of energy *** paper presents a modeling and optimization approach to the operational planning of electric power and natural gas systems, taking into account different energy storage facilities, such as water reservoirs, natural gas storages and line packs of pipelines. The proposed model takes advantage of captures both energy systems synergy and their associated networks. This approach identifies the interactions between the energy storage facilities and their economic impact over their optimal scheduling. The results show the benefits of an integrated operational planning of electric power and natural gas systems, the close interdependency between the energy resources stored in both systems, and the effects of a combined scheduling.

We carry out a comprehensive analysis of a range of wireless network efficiency considerations. Firstly, we explore the properties and the implications of the power-versus bandwidth-efficiency criteria. Secondly, we perform a detailed top-down analysis of a typical commercial wireless network, which emphasizes the inherent differences between the aforementioned two efficiency metrics, while demonstrating that the appropriate choice of the network optimization criterion can have a profound effect on the overall network performance. Finally, we address the issue of resource management and its impact on the definition of the overall system efficiency. Our results suggest that no substantial area spectral efficiency gains beyond those exhibited by the 2G cellular technol- ogy may be economically achieved, and hence, no significant economic gains may be realized by simply increasing the bps/Hz bandwidth efficiency. In contrast, manifold utility and throughput gains as well as substantial Quality of Service enhancements may be attained by the appropriate combination of improved power efficiency, bandwidth expansion as well as the appropriate evolution of the networking paradigm.
