Seamount Mineral Deposits Rare Metals High-Technology Industries
2015/7/7
The near exponential growth in Earth's population and the global economy puts increasing constraints on our planet's finite supply of natural metal resources, and, consequently, there is an increasing...
Characterization of extractable metals from the aquifers with arsenic contamination in the Tsengwen Creek, Taiwan
BCR sequential extraction procedure groundwater hydrochemistry sediment geochemistry
2015/3/10
Arsenic contamination in groundwater is a common groundwater problem worldwide. To manage groundwater resources effectively, it is crucial to determine the arsenic source. Taiwan’s Tsengwen Creek wate...
Potassium Salt Outperforms Precious Metals As a Catalyst
Potassium Salt Precious Metals a Catalyst
2015/3/4
"We have shown for the first time that you can efficiently make carbon–silicon bonds with a safe and inexpensive catalyst based on potassium rather than ultrarare precious metals like platinum, pallad...
A complete view of galaxy evolution: panchromatic luminosity functions and the generation of metals

Incubation-time Based Approach for Dynamic Yielding of Metals
dynamic yielding incubation-time approach failure criteria
2012/9/24
Transition of the materials from elastic to plastic state is modeled by incubation-time based criterion. This approach is similar to the structural -temporal theory for brittle solids fracture develop...
The Galactic dust-to-metals ratio and metallicity using gamma-ray bursts
Gamma-ray burst: general – ISM: abundances – dust, extinction – Galaxy: abundances – X-rays: ISM
2011/10/18
The metallicity and dust-to-metals ratio of the Galaxy are fundamental parameters in understanding the ISM, but there is still uncertainty surrounding these parameters. In this paper, the dust-to-meta...
