World’s first commercial nanostructured bulk metal

When we think of structural materials, we usually imagine something big, strong and bulky, like steel beams in bridges and buildings, and while we are becoming familiar with composites reinforced with carbon nanotubes and ...

Climate change efforts backfire in Brazil's steel industry

New research shows that climate change mitigation efforts in Brazil's steel industry have failed. Instead of reducing greenhouse gas pollution, scientists discovered that programs under an international climate treaty led ...

An 'eye' that measures liquid steel temperatures

Contact-free measurement of the temperature of molten steel boosts the productivity of arc furnaces. That’s why Siemens has developed a system called Simetal RCB Temp, which consists of an optical sensor that can determine ...

Urban SUVs driving huge growth in CO2 emissions: IEA

The undying popularity of sport-utility vehicles has made them the second-biggest contributor to the growth of global CO2 emissions in recent years, just behind the power sector, the head of the International Energy Agency ...

Producing high-tech steel cheaply and efficiently

A new plant for desulfurizing pig iron is reducing the costs of steel production. Developed by Siemens, this innovative process makes it possible to more precisely dose the various desulfurizing agents that are injected into ...
