In steel making, two desirable qualities — strength and ductility — tend to be at odds: Stronger steel is less ductile, and more ductile steel is not as strong. Engineers at Brown University, three Chinese universities, and the Chinese Academy of Sciences have shown that when cylinders of steel are twisted, their strength is improved without sacrificing ductility.

PROVIDENCE, R.I. [Brown University] — Researchers from Brown University and universities in China have found a simple technique that can strengthen steel without sacrificing ductility. The new technique, described in Nature Communications, could produce steel that performs better in a number of structural applications. (more…)

China has potential to be leader in global sustainability

China, with its enormous cities and vast countryside, is a potential star in the ongoing global drama of slashing carbon emissions.

In this week’s Nature, a Michigan State University researcher and an international team of sustainability experts propose a script.

China already is a star in unleashing carbon dioxide emissions. In 2011, it accounted for a quarter of the world’s total. The problems – air pollution, squandered energy resources and economic stresses that squelch growth – also come with tremendous opportunity for China to be leader in slashing emissions. Along the way, China’s vast variety of economic and geographic circumstances offers a chance to set examples for its global neighbors. (more…)

UA Professor Uses Aerospace Materials to Build Endless Green Pipeline

Carbon fiber fabric and lightweight honeycomb materials, plus a mobile manufacturing platform, make infinite pipeline technology cheaper and greener while boosting local economies.

Mo Ehsani, professor emeritus of civil engineering at the University of Arizona, has designed a new, lightweight underground pipe he says could transform the pipeline construction industry.

Instead of conventional concrete or steel, Ehsani’s new pipe consists of a central layer of lightweight plastic honeycomb, similar to that used in the aerospace industry, sandwiched between layers of resin-saturated carbon fiber fabric. (more…)
