Video of the week: 'Material Marvels'- Yale prof explains materials science in about 3 minutes | Ceramic Tech Today
November 9th, 2011 Published on November 9th, 2011 | Edited by: Eileen De Guire Ainissa Ramirez, associate professor at Yale and “science popularizer,” uses bathroom tiles to explain symmetry and five-fold quasicrystal symmetry. Credit: YouTube. Yale associate professor Ainissa Ramirez is a metallurgist, but we gotta love her, anyhow. She’s got the chops for the job, too. There are four so far, each about three minutes long. Our favorite here at CTT is “Quasicrystals,” which is a timely follow-up to the recent awarding of the Nobel Prize to Daniel Shechtman for his discovery of five-fold quasicrystal symmetry. In an email she told us, “I have been an advocate of science education for over a decade, so I started this series on my own [without outside funding].” This career change is a natural extension of other things she’s been doing. Ramirez is also one of the so-called Nifty Fifty (times 2) connected to the USA Science and Engineering Festival. Be sure to check out the videos.

Mining Minerals are essential for modern living, and mining is still the primary method of their extraction. To date, it appears that the main constraints to sustainability in the mining sector derive from the ever-increasing demand for mined resources, the consumption of resources (mostly energy and water) needed to extract and process metals, and the increasing pollution generated by the extraction process. This holds true for both large-scale, often multinational corporate, operations as well as for small-scale or artisanal ventures. Growth of Construction Minerals Extraction In the 20th century, the extraction of construction minerals grew by a factor of 34, while that of ores and industrial minerals by a factor of 27. Environmental, Social & Economic Impacts While the sustainability of extractive industries varies, these operations generally remain associated with a range of environmental and social impacts negatively affecting local communities.

European Commission : Trade : Raw materials
Raw materials are the basis of a large number of industrial value chains in the EU. Specific raw materials are needed to make a wide range of industrial goods such as car engines, mobile phones or wind turbines. EU raw materials' industry in a nutshell A large number of industries use raw materials as inputs, providing a total added value of €1300 billion. 30 million people employed in the raw materials' industrial sector A sustainable supply of particular raw materials is of crucial importance for the development of green technologies EU-Trade raw materials in figures (2011) EU Trade policy and raw materials Raw materials play a significant role for the EU trade policy. . , which further boosted the integration of raw material priorities in EU policies. EU Trade policy is actively committed to ensure that the international raw materials markets operate in a free and transparent way. Results on raw materials
European Commission : Trade : Non-ferrous metals
Goods and services produced in the EU are traded around the globe but their trade can be affected by various aspects of trade policy, such as import tariffs, regulation or discrimination against foreign suppliers. When is a product a good or a service? Goods and services are increasingly linked together. Having access to services is a prerequisite for economic performance of many manufactured products. For example, producers and exporters of textiles, cars or computers cannot be competitive without access to efficient banking, insurance, accountancy, telecom or transport system. The rise of cloud computing means that technical infrastructure, platforms and software are increasingly provided as services on a global basis. Why is it relevant? The EU is the world's biggest exporter of manufactured goods, and is a global market leader for high-quality products. The EU's market access strategy 1. The Partnership is made up of: 2.

BGR - Mineral raw materials
Kounrad Copper Mine, Region Balkhash, Kasachstan Source: BGR The Federal Republic of Germany is one of the world’s largest consumers of mineral resources. Everybody uses about 1,000 tons of raw materials in the course of his life. Of the non-metallic mineral resources, potash and rock salt and the large majority of industrial minerals and rocks originate from domestic production. In order to secure the supply of mineral resources, the state provides the German industry with a scientific-technical and economic infrastructure. In the scope of we analyse the developments in the global commodity markets. Moreover, we are developing new instruments and concepts for the sustainable use of mineral resources in the scope of Mining Economics and Sustainability. In the field of Raw Materials Research, we investigate and assess mineral potentials.
