Upper crustal abundances of trace elements: A revision and update

Heavy metals in particulate and colloidal matter from atmospheric deposition of urban Guangzhou, South China

“…An investigation (Wang et al, 2005) used the earth's crustal mean abundances of the metal elements given by Gallet et al (1998) and Hu and Gao (2008). Si, Al, Fe or Ti is frequently used as the reference element.…”

High-temperature thermoelectric properties ofn-type PbSe doped with Ga, In, and Pb

“…17,18 Finally, Se is less expensive and ∼50 times more abundant than Te in the Earths crust. 19 The aforementioned attractive combination of properties has prompted us to study in detail the thermoelectric behavior of PbSe at high temperatures. Compared to PbTe, the thermoelectric and transport properties of PbSe and its solid solutions have attracted only limited attention, despite reports for a promising ZT ∼ 0.6 around 700 K. 4 Nemov et al have studied the amphoteric doping action of Bi in PbSe by means of the Hall effect and concluded that only a small fraction of Bi enters anionic sites at high Bi concentrations.…”
