In a paper published in the Science and Technology of Advanced Materials, Bhadeshia introduces the world's first bulk nanostructured metal in commercial production.

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 nanofibers, it is yet hard to believe that the structure of bulk homogenous metals can be controlled at the nanoscale with commercial-scale production

In a paper published in the Science and Technology of Advanced Materials, Bhadeshia introduces the world's first bulk nanostructured metal in commercial production. The nanostructure-controlled high-strength bainitic steel has the thickness of bainitic ferrite platelets controlled between 20 and 50 nm.

The review paper explains why nanostructure plays an important role in strengthening materials, and the conditions required to design and develop such "nanostructured" materials. In particular, the biggest challenge is to keep the production cost as low as that of bottled water.

So, what magic is needed to produce low-cost nanostructured bulk steel? The answer is simple -- keep the bulk at 200 C for 10 days, which will lead to the formation of plate-like bainitic structure. One deficiency of the material is that it is yet difficult to weld, but the author lays out possible solutions to overcome this.

Crude Oil Prices Bounce Back After Falling Below $100 a Barrel

TheStreet (July 16, 2014) Oil Futures are bouncing back after tumbling below $100 a barrel for the first time since May yesterday. Jeff Grossman is the president of BRG Brokerage and trades at the NYMEX. Grossman tells TheStreet the Middle East is always a concern for oil traders. Oil prices were pushed down in recent weeks on Libya increasing its production. Supply disruptions in Iraq fading also contributed to prices falling. News from China's economic front showing a growth for the second quarter also calmed fears on its slowdown. Jeff Grossman talks to TheStreet's Susannah Lee on this and more on the Energy Department's Energy Information Administration (EIA) report. Video provided by TheStreet
