Bulletin of Chinese Academy of Sciences (Chinese Version)

As the world's major consumers of critical minerals and China's primary competitors, US and the EU have developed comprehensive and systematic critical mineral strategies, which have significant impact on China's resource security. To assist in developing China's critical mineral strategy, by thoroughly examining the critical mineral strategies of US and EU, this study finds their strategic attempts to slow China's development, summarizes their characteristics in the preparation, implementation mechanism, and main strategic measures, and, based on this, proposes suggestions for raising the safety level of China's critical minerals.

Challenges And Security Strategies Of China’S Critical Metals Supply For Carbon Neutrality Pledge, Weiqiang Chen, Peng Wang, Weiqiong Zhong

Bulletin of Chinese Academy of Sciences (Chinese Version)

The grand transition to low-carbon energy system is essential to bend the growing carbon emission and further achieve the dual carbon goals. Critical metals such as rare earth elements, lithium, cobalt, nickel, and platinum are widely considered as the material base to support low-carbon technologies. However, given the supply of those metals are scarce and risky, the emerging conflicts between their supply and demand have spurred global attention and competition among countries. This study aims to explore the linkage between critical metals and low-carbon energy systems with a particular focus on the bottlenecks of China's supply chains of those critical …

Rare earth is one of the key minerals in the global competition. At present, the global rare earth resources and supply pattern are changing, and Western countries are actively building a supply chain to replace China. This paper describes the evolution of China's rare earth supply and demand pattern from the perspective of elements, analyzes the dislocation of supply and demand of China's rare earth elements and the challenges it faces under the great changes, and puts forward the balanced utilization strategy of rare earth elements, which provides an optimization plan for promoting the globalization of the industrial chain and …

Security Of China’S Strategic And Critical Minerals Under Background Of Great Power Competition, Anjian Wang, Xiaojing Yuan

Bulletin of Chinese Academy of Sciences (Chinese Version)

Strategic and critical minerals are a type of resource that is essential to the country's economic development, indispensable to strategic emerging industries, and closely related to geopolitics. The types of strategic and critical minerals show some laws of spatial-temporal evolution due to the different stages of national economic development, economic structure and global industrial division of labor. Especially since the new century, with the rapid development of strategic emerging industries such as information technology, artificial intelligence and renewable energy, the connotation of strategic critical minerals has been continuously extended and closely connected with the industrial chain, highlighting its important position …

Recycling Of Critical Metals In Green And Low-Carbon Transition: Strategies And Countermeasures, Gang Liu, Litao Liu, Xin Ouyang, Qiance Liu, Xiang Li, Qiang Yan

Bulletin of Chinese Academy of Sciences (Chinese Version)

As green and low-carbon transition has gained world-wide recognition and become the inherent requirement of fully building a modern socialist China, the consumption of critical metals will increase drastically in the next decades. Meanwhile, this will mean a continually increasing potential of critical metals recycling. Facing changes and pandemic unseen in a century and increasing geopolitical conflicts, it has become a strategic consensus on the national security level for Western countries like the United States and Europe Union to acknowledge and enhance the role of recycling in secure provision of critical metals. Here, in this study, we have discussed the …

Chemical Mapping To Evaluate Post-Depositional Diagenesis Among The Earliest Ceramics In The Teotihuacan Valley, Mexico, Wesley D. Stoner, Barry J. Shaulis

Anthropology Faculty Publications and Presentations

Chemical and mineral sourcing techniques are commonly employed in archaeology to reconstruct patterns of ceramic exchange and raw material procurement practices for the past, but the effects of post-depositional diagenesis are still often ignored despite a number of key studies warning that the composition of ceramics from archaeological deposits often diverges greatly from their original composition at the time of production. This current study on diagenesis derives from a large chemical and petrographic analysis of some of the earliest ceramics (1500-100 cal Before Common Era [BCE]) in the Basin of Mexico at a time when the development of ceramic trade …

Radical Social Ecology As Deep Pragmatism: A Call To The Abolition Of Systemic Dissonance And The Minimization Of Entropic Chaos, Arielle Brender

Student Theses 2015-Present

This paper aims to shed light on the dissonance caused by the superimposition of Dominant Human Systems on Natural Systems. I highlight the synthetic nature of Dominant Human Systems as egoic and linguistic phenomenon manufactured by a mere portion of the human population, which renders them inherently oppressive unto peoples and landscapes whose wisdom were barred from the design process. In pursuing a radical pragmatic approach to mending the simultaneous oppression and destruction of the human being and the earth, I highlight the necessity of minimizing entropic chaos caused by excess energy expenditure, an essential feature of systems that aim …

Murray Energy Corporation V. Mccarthy, Sarah M. Danno

Public Land & Resources Law Review

Holding that the widespread effects of environmental regulation on the coal industry constituted sufficient importance, the Northern District of West Virginia ordered the Environmental Protection Agency to conduct analysis on employment loss and plant reduction resulting from regulatory effects. In admonishing the EPA’s inaction, the court ruled that the Agency had a non-discretionary duty to evaluate employment and plant reduction. Furthermore, the court held that the EPA’s attempt to put forth general reports in place of required evaluations was an invalid attempt to circumvent its statutory duty.

The Role Of The State, Multinational Oil Companies, International Law & The International Community: Intersection Of Human Rights & Environmental Degradation Climate Change In The 21st Century Caused By Traditional Extractive Practices, The Amazon Rainforest, Indigenous People And Universal Jurisdiction To Resolve The Accountability Issue, Marcela Cabrera Luna

Master's Theses

Local, national and international conventions that protect indigenous sovereignty and their territories, where many of the resources are extracted from by multinational corporations (MNCs) particularly oil, the number one commodity of the world and cause of climate change, continue to be jeopardized because of the lack of a clear international legal framework that can protect them and potentially hold multinationals accountable for their actions. These practices are causing not only environmental issues to the indigenous and surrounding communities, but climate change is in fact, the real human rights issue of the 21^st century and it affects everyone. By using …

Using Conservative And Biological Tracers To Better Understand The Transport Of Agricultural Contaminants From Soil Water Through The Epikarstic Zone, Brian Ham

Masters Theses & Specialist Projects

Agriculture contamination is very common in karst systems due to the vulnerability of these aquifers. Animal waste is often spread across crop land to enrich the soil with nitrates and phosphates. Herbicides and pesticides are also applied to the crops. The transport of these pollutants through the soil and epikarst is a difficult process to monitor due to the complex, heterogeneous behavior of the groundwater as it makes its way down to the aquifer below.

An experimental site at Crumps Cave lended a unique opportunity to monitor the vadose zone at a waterfall in the cave below. A previous dye …

Analysis Of Lunar Basalt Flows In Oceanus Procellarum Using Clementine Data, Noel William Jackson

OES Theses and Dissertations

Remote sensing analyses of data set taken by Clementine in 1994 permit new observations about mineral distribution on the lunar surface, basalt flow stratigraphy, and thus the geologic evolution of the Moon. The northern section of Oceanus Procellarum contains numerous impact craters which penetrated the basalt and thus can be used as natural probes to estimate the number and thicknesses of flows.

I constructed a mosaic taken in three frequencies ( 415 nm, 750 nm, 950 nm), and a Ratio Image (750/415 = red, 750/950 = green, 415/750 = blue). On such an image, red indicates the iron-poor mature highland …
