Summary:
While there have been significant breakthroughs in nano-manufacturing, there has been much less progress on measurement technologies that can provide information about nanostructures made from multiple integrated materials. Researchers now report new diagnostic tools that can support cutting-edge nano-manufacturing. Using atomic force microscope based infrared spectroscopy to characterize polymer nanostructures and systems of integrated polymer nanostructures, researchers were able to chemically analyze polymer lines as small as 100 nm.

Nanotechnology-based materials identification enables critically needed chemical metrology for nano-manufacturing.

One of the key achievements of the nanotechnology era is the development of manufacturing technologies that can fabricate nanostructures formed from multiple materials. Such nanometer-scale integration of composite materials has enabled innovations in electronic devices, solar cells, and medical diagnostics.

While there have been significant breakthroughs in nano-manufacturing, there has been much less progress on measurement technologies that can provide information about nanostructures made from multiple integrated materials. Researchers at the University of Illinois Urbana-Champaign and Anasys Instruments Inc. now report new diagnostic tools that can support cutting-edge nano-manufacturing.

"We have used atomic force microscope based infrared spectroscopy (AFM-IR) to characterize polymer nanostructures and systems of integrated polymer nanostructures," said William King, the College of Engineering Bliss Professor in the Department of Mechanical Science and Engineering at Illinois. "In this research, we have been able to chemically analyze polymer lines as small as 100 nm. We can also clearly distinguish different nanopatterned polymers using their infrared absorption spectra as obtained by the AFM-IR technique."

In AFM-IR, a rapidly pulsed infrared (IR) laser is directed on upon a thin sample which absorbs the IR light and undergoes rapid thermomechanical expansion. An AFM tip in contact with the polymer nanostructure resonates in response to the expansion, and this resonance is measured by the AFM.

"While nanotechnologists have long been interested in the manufacturing of integrated nanostructures, they have been limited by the lack of tools that can identify material composition at the nanometer scale." said Craig Prater, co-author on the study and Chief Technology Officer of Anasys Instruments Inc. "The AFM-IR technique offers the unique capability to simultaneously map the nanoscale morphology and perform chemical analysis at the nanoscale."

The authors are Jonathan Felts and William King of University of Illinois Urbana-Champaign and Kevin Kjoller, Michael Lo, and Craig Prater of Anasys Instruments Inc.

The research was sponsored by the Defense Advanced Research Projects Agency, the Air Force Office of Scientific Research, and the Department of Energy.

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
