Lead constitutes only about 12.5 wtppm (weight part per million) of the earth's crust, but concentrated lead ore deposits make it easy to mine. Lead and its alloys are used in a wide range of technical applications because of their low melting point, ease of casting, high density, softness and high formability at room temperature, excellent resistance ...

Tunneling in lead-lead oxide-lead junctions
Journal of Applied Physics, 1974A detailed investigation of tunneling in Pb/PbO/Pb junctions has been carried out, in an attempt to independently measure several of the parameters known to enter the tunneling problem. In particular, the thickness of the tunnel barrier (orthorhombic PbO thermally grown in situ in an ultraclean vacuum system) has been measured ellipsometrically, and ...

This thesis analyses how and why China has incorporated climate and energy-transition narratives into its Belt and Road Initiative (BRI), and how these narratives are translated into practice in Chinese energy engagement in Africa. Drawing on constructivist role theory, it conceptualizes China’s climate engagement as a form of “facilitative leadership”
