Negative permittivity is a required physical property of metamaterials which has been widely used in some emerging and unconventional applications, such as cloaking, perfect lens and perfect wave absorption. In addition to periodic meta-structured units, a composite with conductive networks,...

Copper sulfides (Cu x S) have been considered as candidates for sodium ion battery (SIB) anodes because they are environmentally friendly and have large theoretical capacity. Whereas, the cycle stability and capacity of Cu x S are still challenge for their practical applications. Here,...

In this work, we highlights 5G antenna (~ 28GHz) using Al 2 O 3 -doped CaO-MgO-SiO 2 glass ceramics with reducing-resistant behavior co-fired with copper electrode. The diffusion behavior between copper electrode and low-temperature-co-fired-ceramics (LTCC) were also studied. Amphoteric Al 3+...

"In this book, Duncan Money convincingly argues that the actions, organisations and identities of the White mineworkers who came to Zambia's Copperbelt from the 1920s onwards were shaped by their international connections, experiences and mobility. Drawing on research from archives on four...

Southern African countries-mainly Zambia and the Democratic Republic of the Congo-account for around a seventh of global production of copper. In the 2010s, they imported over a third of the associated capital goods and components from South Africa. Given this strength, some observers suggest...

This chapter represents a comparative study of the emergence of environmental policies in the Chilean and Swedish copper industry. The chapter identifies a number of key factors which helps to explain dissimilar characteristics of actions to protect the environment in both countries as well as...

This paper presents a study on the importance of copper production in the State of Sonora, Mexico. Important data will be presented with total relevance to the current economic framework in which it will be possible to determine through a thorough investigation the reason why Sonora as a state...

How should resource-rich economies handle the balance of payments adjustment required after commodity price declines? This paper addresses the question theoretically by developing a simple two-period multi-sector model based on Nakatani (2016) to compare different exchange rate policies, and...

"This is a history of copper as a commodity, which focuses on copper produced in Swansea, Wales, and sold around the world. Between the 1770s and the 1840s, the Swansea district produced nearly half of the world's smelted copper. This book traces the history of copper making in Britain beginning...

This Working Paper presents a brief but comprehensive graphical overview of copper contained in international trade, from copper concentrates through to finished products. Extensive data checks and a simple consolidation method were performed before visualizing the data on world maps. While data...

The standard real-options model predicts that increased uncertainty discourages investment. When projects are large and take time to build, however, this prediction can be reversed. We investigate the investment/uncertainty relationship empirically using historical data on opening dates of new...

The objective of this paper is to value as a Real Option the License of a copper mine in the exploration stage. We conceive the License of a copper mine, as the value of a call option that gives us the right to invest in the next stage. The underlying asset is the Net Present Value (NPV) of the...

This report is part of a series produced by the World Bank's Africa Finance and Private Sector Development Unit (AFTFP). This report explores the potential contribution that the copper mining industry could make to jobs and prosperity in Zambia, and what it will take to achieve this potential....

By virtue of its intrinsic properties, copper is used extensively in many manufacturing industries, from the production of power cables to consumer electronics. Statistics from the World Bureau of Metal Statistics (2012) reveal that global refined copper consumption reached over 19.5 million...
