On the Complexity and Behaviour of Cryptocurrencies Compared to Other Markets [PDF]
, 2014 We show that the behaviour of Bitcoin has interesting similarities to stock and precious metal markets, such as gold and silver. We report that whilst Litecoin, the second largest cryptocurrency, closely follows Bitcoin's behaviour, it does not show all ...

Very High Output Thermoelectric Devices Based on ITO Nanocomposites [PDF]
A material having useful thermoelectric properties was synthesized by combining indium-tin-oxide (ITO) with a NiCoCrAlY alloy/alumina cermet. This material had a very large Seebeck coefficient with electromotive-force-versustemperature behavior that is ...

Shape-Evolution and Growth Mechanism of Fe3O4 Polyhedrons
Advances in Materials Science and Engineering, 2015 The shape evolution of spinel-structured Fe3O4 was systematically investigated using a one-pot solvothermal route. Using FeCl3·6H2O as the precursor, triangular and hexagonal plates, octahedrons, dodecahedrons, and spherical Fe3O4 were obtained by ...
