First-principles computation methods play an important role in developing and designing new magnesium alloys. In this article, we present an overview of the first-principles modeling techniques used in recent years to simulate ideal models of the structure of strengthening compounds in Mg alloys. For typical Mg compounds, structural stability, mechanical properties, electronic structure and thermodynamic properties have been discussed. Specifically, the elastic anisotropies of these compounds are examined, which is highly correlated with the possibility of inducing micro-cracks. Furthermore, some heterogeneous nucleation interfaces investigated by first-principles method are reviewed. Some of the theoretical results are compared with available experimental observations. We hope to illustrate that the first-principles computation can help to accelerate the design of new Mg-based materials and the development of materials genome initiative. Remaining problems and future directions in this research field are considered. [ABSTRACT FROM AUTHOR]

In order to essentially tackle climate change issues and achieve sustainable development in both developed and developing countries, the overwhelming triple-win solution for energy, environment and economy is to coordinate both low-carbon technology and economic growth. Public fund investment plays an important role as a financial instrument for developing countries in achieving such a goal. However, an effective system should be introduced to steer private capital efficiently and promote closer cooperation among private and public sectors under limited resources and funds. This article provides a rational overview for Taiwan's nationally appropriate mitigation actions and supplementary GHGs emission reduction actions, along with a vision discussion and policy thinking in developing Taiwan's low-carbon financial and economic instruments, and presents the perspectives and experiences of the low-carbon financing scheme in accelerating the Green New Deal, developing cleaner energy technologies, and creating green business and jobs.
