NBC News Investigates Child Labor & Unsafe Conditions in Mica Mining Industry

Categories: Popular Press|Tags: |

Mica is the name applied to a group of minerals that form in layers at once flexible and strong. A longtime staple of the cosmetics industry, mica is known for adding sparkle to makeup products and paints. But it’s also prized in the electronics and automotive worlds due to its ability to transmit electric force without overheating, even under extreme temperatures. NBC News reports from the Mica mines of Madagascar, where child labor and unsafe working conditions are the norm. NBC News

Why We Need to Care About Critical Materials

From the Stone Age to the present, mineral commodities have been essential ingredients for building and advancing civilization. Products built with materials derived from mineral resources include homes and office buildings; cars and roads; computers, televisions, and smartphones; and jet fighters and other military hardware needed to defend the Nation. In short, minerals are essential to advance and protect modern society.

Earth-abundant catalysts for electrochemical and photoelectrochemical water splitting

Categories: Scholarly Resources|Tags: |

Sunlight is by far the most plentiful renewable energy resource, providing Earth with enough power to meet all of humanity’s needs several hundred times over. However, it is both diffuse and intermittent, which presents problems regarding how best to harvest this energy and store it for times when the sun is not shining. This review investigates progress towards such electrocatalysts, with special emphasis on how they might be incorporated into photoelectrocatalytic water-splitting systems and the challenges that remain in developing these devices.

Life Cycle Assessment of Metals: A Scientific Synthesis

Categories: Scholarly Resources|Tags: |

Life Cycle Assessment of Metals: A Scientific Synthesis. We have assembled extensive information on the cradle-to-gate environmental burdens of 63 metals in their major use forms, and illustrated the interconnectedness of metal production systems. Related cumulative energy use, global warming potential, human health implications and ecosystem damage are estimated by metal life cycle stage (i.e., mining, purification, and refining).

Substitution strategies for reducing the use of rare earths in wind turbines

Categories: Scholarly Resources|Tags: |

Resources Policy Like many other low-carbon energy technologies, wind energy is currently at risk due to potential bottlenecks in its dependence on critical rare earth elements such as Nd, Pr, Dy, and Tb, which are used in permanent magnet synchronous generators.

This paper evaluates up-to-date substitution ideas for meeting a projected estimation of increase in total annual demand for rare earths, which is 1.7 times from 2015 to 2020.

ELECTROMOBILITY

Categories: Popular Press|Tags: |

If you don’t drive an electric vehicle (EV) yet, you probably will soon. With more and more automakers going green, producing new EVs that promise greater performance and increased driving range, your next truck, sports car or crossover sport utility vehicle, is likely to be electric. But there’s a catch to this bold new world of EVs.
