they are going to be highly valuable cornerstone companies in the global economy, eating markets far larger than the technology industry has historically been able to pursue.

$286 million to Solyndra of Fremont (photovoltaics), $82. 5 million to Tesla Motors of San Carlos (electric vehicles) and $60 million to Serious Materials in Sunnyvale (energy-efficient building materials.

#The World's Most Advanced Building material Is...Woodon a cloudy day in early October the architect Andrew Waugh circles the base of a nondescript apartment tower in Shoreditch a neighborhood in East London.

Put differently the world s urban future may just lie in its oldest building material. When most people think of wood architecture they imagine a balloon r rather a balloon frame the lightweight

But over the last two decades architects and engineers have begun to rethink the possibilities of wood as a structural building material.

if it has no defects--its intrinsic strength says James Hone professor of mechanical engineering who led the study with Jeffrey Kysar professor of mechanical engineering.

and were able to create test samples without harming the graphene notes the paper's lead author Gwan-Hyoung Lee a postdoctoral fellow in the Hone lab. Our findings clearly correct the mistaken consensus that grain boundaries of graphene

In its perfect crystalline form graphene (a one-atom-thick carbon layer) is the strongest material ever measured as the Columbia Engineering team reported in Science in 2008--so strong that as Hone observed it would take an elephant balanced on a pencil to break through a sheet

or more in size says Hone. This strength will be invaluable as scientists continue to develop new flexible electronics and ultrastrong composite materials.

and to investigate how those defects change its properties says James Hone professor of mechanical engineering at Columbia Engineering who led the study.

While these tiny specimens are fine for scientific studies notes Daniel Chenet a Phd in Hone's lab

The grain boundaries become important in any technology says Hone. Say for example we want to make a solar cell.

and are now developing techniques to integrate it into many new technologies Hone adds. We're only just beginning to scratch the surface of

The growth and electrical measurements were made by the Hone lab in mechanical engineering; the optical measurements were carried out in the Tony Heinz lab in physics.

or other building materials we use so much of it that concrete production accounts for between 3 to 8 percent of global carbon dioxide emissions Riding said.
