Abstract

CeO2/multi-walled carbon nanotubes (CeO2/MWCNTs) composites were successfully synthesized via one-step hydrothermal method. The crystal morphology, structure and electromagnetic parameters of the composites were characterized by X-ray diffraction, X-ray photoelectron spectroscopy, field-emission scanning electron microscopy, high-resolution transmission electron microscopy and vector network analyzer. The microwave absorption performances of CeO2/MWCNTs composites can be evaluated between 2 and 18 GHz frequency range, which is based on transmission line theory. The results demonstrated that fluorite CeO2 nanoparticles were anchored on MWCNTs. The CeO2/MWCNTs composites can reach the minimum reflection loss of − 34.64 dB at 16.24 GHz under the coating thickness of 5 mm, and the frequency bandwidth exceeding − 10 dB was 2.88 GHz. The microwave absorbing properties of the CeO2/MWCNTs composites were mainly attributed to the synergistic effect of dielectric and conductive loss, which were caused by the oxygen vacancies of CeO2. Moreover, charge polarization and interfacial polarization occurring in the composites are beneficial to microwave absorption. [ABSTRACT FROM AUTHOR]

Abstract

As more and more people go abroad to study, higher education industry has been attracted the world's attention. At present, there is a big trade deficit in education services which shows in less domestic and foreign students go to China after graduation. This paper analyzes the development trend of China's overseas higher education objectively. According to this situation, and proposes further countermeasures: Promote market-oriented reform of higher education; Improve the business and service environment in order to attract more overseas students to return; Increase educational investment to establish high-quality platforms and grasp the openness degree of trade correctly; Strengthen exploiting of domestic vocational training and regulate foreign agencies' accessing to China's education markets.

24. Seafarer training and rural development in China: a survey report

Author

Wu, Bin, Robinson, Bernadette, Chen, Aijuan, Li, Pinfang, Wu, Bin, Robinson, Bernadette, Chen, Aijuan, and Li, Pinfang

Abstract

So far, most studies of the relationship between migration and development in rural China pay attention to rural-urban migration. As a consequence, less is known about international labour migration and access to it by sending communities. This phenomenon has two aspects: international chain migration via social networks, which happen mainly along coastal areas; and international contract labour migration from the poor areas of inland China. The research reported in this article examines the latter, exploring how the rural poor gain access to opportunities, what they cost and what their perceived benefits are.
