Decommissioning the UK's offshore oil and gas infrastructure will cost the taxpayer £24 billion, according to estimates from HMRC. So why can't we leave man-made structures in the sea and thereby save the cost of removal ...

Memory steel—a new material for the strengthening of buildings

A new building material called memory steel, developed at Empa is about to be launched on the market. The material can be used to reinforce new and existing concrete structures. When the material is heated (one-time), prestressing ...

Understanding corrosion processes in concrete

Will reinforced concrete bridges still be standing for years to come, or has corrosion already set in? ETH scientists have discovered that previous concrete samples were too small to allow a reliable statement on the condition ...

Efficient structures help build a sustainable future

When envisioning a new structure, engineers often have to balance design choices against the environmental impact of materials used. It is estimated that 40 to 50 percent of greenhouse gases are produced by the construction ...

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 ...
