This paper examines the impact of spillover effects of energy transition metals on the Chilean economy. With the increasing demand for metals like copper and lithium due to the growth in renewable energies and electromobility, metal abundant countries like Chile must ready themselves to remain...

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+...

This senior law thesis examines the place of copper extraction in the Chilean economy and political system and the role that legal regulation played since 1850 up to the late 1960s. Copper has been the principal product of the economy and main source of foreign exchange and government revenue....

Cu(II)-EDTA is a highly stable typical metal-organic complex in a wide pH range (3.0-12.0) and difficult to deeply purify Cu(II) by conventional precipitation methods. In this study, Fe(III) replacement/diethyldithiocarbamate (DDTC) precipitation combined process was proposed as a promising...

Vanadium sulfides are appeared and investigated for the application of sodium-ion batteries (SIBs) due to their adjustable structure and high theoretical capacity. Nevertheless, their inferior sodiation/desodiation kinetics during cycling and convoluted Na + storage mechanism severely restricts...

The development of highly efficient and stable electrocatalysts for their application in electrochemical detection is desirable. Herein, a new copper nanowires (CuNWs) modified electrode was fabricated by coating poly(dimethyl diallyl ammonium chloride) (PDDA) stabilized CuNWs composite onto the...

This paper demonstrates a selective laser melting method to produce a metal matrix composite capable of enhancing the thermal conductivity of 316L stainless steel using a jettable Cu ink. A novel canister for controlling the atmosphere surrounding a powder bed during selective laser melting, was...

Automotive engines are made from different materials like steel, aluminium, copper, and brass. These materials usually come in contact with the fuel. This study provides corrosion rates of automotive materials copper, aluminium, and stainless steel 316l when coming in contact with chicken fat...

Under Section 201 of the 1974 Trade Act, a domestic industry can obtain temporary protection against imports by demonstrating before the International Trade Commission that it has been injured, and that imports have been the"substantial cause" of injury --i.e.,"a cause which is important and not...

Der Glasfaserausbau in Frankreich ist bereits relativ weit fortgeschritten und der Ausbauplan bis 2025 ist bereits zu über 92% fest kontrahiert. Noch besteht eine Nachfragelücke zwischen den bereits ausgebauten und den aktiv in Betrieb genommenen Glasfaseranschlüssen. Es gibt weder eine klar...

The motivation of this paper is to identify the effect of treatment charge (TC) on LME (London Metal Exchange) copper prices. It is a fundamental variable as a supply side factor, because it is related to the smelting process and reflects the level of concentrates market tightness. To examine...

Introduction and Background -- Rhokana/Nkana During the Great Depression: Problems and Challenges -- Financial Incentives of War: Rhokana/Nkana During the Second World War and Korean Crisis, 1939-1953 -- Rhokana/Nkana and the Political Economy of the Central African Federation, 1953-1963 --...

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...

Commodity prices and their secular trends are at the core of many different development theories, particularly relevant for the Latin American region, like the Prebisch-Singer hypothesis, the natural resource curse theory or the somehow malthusian scarcity prediction. In this article we review...

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 is about understanding the cycle of global copper price booms and busts over Zambia's economic history. We explore how the mining industry has been managed, and wider economic management during boom periods. We find that successive Zambian governments did not use copper revenues to...

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...

"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...

Subglobal climate policies induce changes in international competitiveness and favor a relocation of carbon-emitting activities to non-abating regions. In this paper, we evaluate the potential for CO2 abatement and the emissions 'leakage' effect in the copper industry, a prominent...

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 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...
