Sommario/riassunto |

Iron Oxides play an important role in numerous disciplines. Since the publication of the first edition, there has been a surge of interest in synthetic fine to ultrafine iron oxides in a wide range of scientific and technological disciplines, especially in mineralogy, geosciences and environmental science and in various branches of technology. As before, the main aim of the second edition is to present reliable, well-tested, up-to-date methods of synthesizing pure iron oxides. The section on monodispersed particles, presently of great interest to industry, has been expanded. Furthermore the me |

Sommario/riassunto |
|
This book provides an overview of the rapid development Beijing has seen in a wide range of areas in 2018, both in itself and as an integral part of a larger region, as China’s economic development continues to improve in overall quality and regional coordination. General reports on progress Beijing made and problems it faced in 2018 in improving its economy, public services, and municipal and community governance, urban planning, and funding for innovations are followed by case |

studies that look at best practices and how they can be applied towards promoting coordinated development of the Beijing-Tianjin-Hebei region. The strategy features prominently in the outlook contributors present for the greater metropolitan area of Beijing for 2019. This book is a valuable source of reference for anyone trying to gain a better understanding the what, how, and why in relation to one of the world’s fastest growing mega-cities. The Beijing Academy of Social Sciences is a government-affiliated think tank, compiling economic, population and other statistics for the public interest. |
