OXIS Energy is Leading the World With its Latest Cell Energy Density and Capacity

In 2014 OXIS has developed its largest Lithium Sulfur cell achieving in excess of 300Wh/kg. This outperforms Lithium ion technology that has dominated the performance battery market for many years. In addition OXIS has achieved an increase in cell capacity to a 25Ah cell – a world first.

Vale examines Superstack’s future

The Superstack, Canada's second tallest freestanding structure, and one of Sudbury's most iconic landmarks, could eventually be torn down, according to Vale's vice-president of Ontario and UK Operations, Kelly Strong. Vale will determine what it should do with the Superstack by the end of 2014. File photo.

The Superstack, Canada’s second tallest freestanding structure, and one of Sudbury’s most iconic landmarks, could eventually be torn down, according to Vale’s vice-president of Ontario and UK Operations, Kelly Strong. Vale will determine what it should do with the Superstack by the end of 2014.

Miner ponders tearing down iconic Sudbury structure

 Some call it an eyesore, while many others see it as one of Sudbury’s most easily identifiable and iconic landmarks.

By the end of the year, Vale is expected to determine the future of the Superstack, and decide whether or not it should be torn down.

“The reality is that there’s very little SO2 (sulphur dioxide) coming up the stack and it doesn’t make a lot of sense for use to use the stack further,” said Kelly Strong, Vale’s vice-president of Ontario and UK operations.

Vale Indonesia Profit Surges 175 Percent in First 9 Months

Jakarta. Profit at Vale Indonesia, the local unit of Brazilian mining giant Vale, climbed by 175 percent in the first nine months of this year from the same period last year, due largely to the higher selling price of nickel and lower cost of revenue, the company said in a statement on Friday.

Net income at Indonesia’s largest nickel producer was recorded at $130.4 million in the January-September period, from $47.3 million last year.

Nickel-based alloys are desirable for their resistance to heat and corrosion. Arcam, with its Electron Beam Melting systems, has added nickel-based Inconel 718 to its material list, joining EOS, 3D Systems, Concept Laser, Renishaw and SLM Solutions, among others, in offering this material for sintering/melting.

Amazing machines poised to fly travelers into a new era

The laser melts fine metal powder into a precisely shaped solid metal layer so thin that it’s one-third the diameter of a human hair. When it’s done, the result is an extremely precise, complicated jet fuel nozzle — no assembly required. The old way of making nozzles required welding together about 25 separate parts.

GE engineers said it represents the first time additive manufacturing has been used to create a jet engine component tasked with such an important role under high temperature conditions.

Nickel Leads Industrial Metals Higher on Japan Stimulus

Nickel led most industrial metals higher after the Bank of Japan unexpectedly increased monetary stimulus and before an official gauge of Chinese manufacturing.

The BOJ said it will increase holdings of government bonds by 80 trillion yen ($722 billion). A manufacturing purchasing managers’ index reading for October in China, the biggest metals user, will be 51.2 compared with 51.1 in September, according to a Bloomberg News survey before the data tomorrow. A number above 50 signals expansion.

Nickel price jumps again – Chinese stocks gone by April

Capital Economics forecasts nickel to reach $21,000 next year, but others are even more bullish. Citibank sees $24,000 next year and a peak of $30,000 while Scotiabank predicts $23,700 in 2015 and highs of $26,500 the year after that.

New solar power nanotechnology material converts 90 percent of captured light into heat

Increasing the light absorption across the wide solar spectrum has important implications for applications in solar-thermal and photovoltaic energy conversion.

Copper oxide (CuO) nanowires (NWs) and cobalt oxide (Co3O4) nanoparticles (NPs). Copper oxide NWs of 100–200 nm in diameter and 5 µm long are grown thermally on copper foil in air and cobalt oxide NPs of 100–200 nm in diameter are synthesized hydrothermally. Tandem structures of spectrally selective coating (SSC) layer are built with three different methods: spray-coating, dip-coating of cobalt oxide NPs into copper oxide NWs forest, and transferring of copper oxide NWs layer onto cobalt oxide NPs layer. The tandem-structured SSC layers fabricated from the spray-coating, dip-coating and transferring methods exhibit figure of merit (FOM) values of 0.875, 0.892 and 0.886, respectively, which are significantly higher than that of the starting copper oxide NWs (FOM=0.858) and cobalt oxide NPs (FOM=0.854). Results demonstrate the efficacy of using novel tandem structures for enhanced light absorption of solar spectrum, which will find broad applications in solar energy conversion.
