Currently the leading suppliers into Brazil are China, the US, South Korea and Germany. Total imports amounted to US$663 million in 2010, a 40% increase over 2009.

Copper stockpiles held in duty-free warehouses in China, the top user, may be re-exported after surging to as much as 350,000 tons from almost none at the start of the year, according to Xi'an Maike Metal International Group. "We can hardly find buyers for refined copper," said Luo Shengzhang, general manager of the copper department at Xi'an Maike. The company ranks among the country's three biggest importers, according to the executive. "China's got to export some copper from now and next year," Luo said in an interview.

The IPO in London and Hong Kong is set to be the largest in history for the UK market and the third largest in Europe – only the privatisations of Deutsche Telekon and Enel of Italy in the late 1990s were bigger. In the process it will transform a highly publicity shy company into a publicly listed $60bn giant, with all the attendant glare. Unsurprisingly bankers – whether involved in the deal or not – consider it the event of the year whose importance reaches beyond the capital markets.

At its essence, a nanogrid is simply a small microgrid, typically serving a single building or a single load.  Nanogrids, however, have the ability to fill increasingly important niches within the larger power sector, serving as modular building blocks for energy services that support applications ranging from emergency power for commercial buildings to the provision of basic electricity services for people living in extreme poverty. 

Ukrainian manufacturers of non-ferrous metals, related products and derivatives exporting to the European Union (EU) could benefit from a planned scrapping of import studies charged on products traded between them.

The company has announced that its all-important unified environmental authorisation (AAU) has now been signed off by the minister of environment and spatial planning, María Jesús Serrano

The books focusses on marketing aspects such as advertising, codes of conduct and import/export regulations.

Bell Labs is back, recently setting a new world record of 10 gigabit per second over existing copper wires. Why is this important? Because it solves the fiber-to-residence problem. Fiber cables for high-speed Internet services are being laid all throughout the country and world, but at a relatively slow rate due to the "curb-to-residence" problem. Many home owners are reluctant to let their lawns be dug up to lay fiber from the curb to the house, and many Internet providers are reluctant to incur the cost. Now Alcatel-Lucent's Bell Labs (Murray Hill, New Jersey) has a invented a solution -- a method of running 1-to-10 gigabit per second broadband signals from the curb to the residence using the existing copper telephone lines already there.

Researchers at the University of Texas at San Antonio say that they have produced a new phase map of the copper-nickel nanoalloy – a technologically important catalyst used in a wide range of industrial processes – that goes a long way in explaining how the size and shape of the nanoparticles affect the alloy’s melting temperature. The map could allow engineers to make specific types of Cu-Ni structures depending on the application required by simply tuning alloy synthesis parameters.
