Argonne National Laboratory Center for Nanoscale Materials U.S. Department of Energy

It is a great pleasure to open this second issue of the CNM’s newsletter with a very exciting update. Following two years in which the CNM’s funding was more constrained than we had hoped, the FY 2009 Omnibus Funding Bill has provided the CNM with an increased operating budget for this fiscal year that reaches the Department of Energy's (DOE’s) original vision for the Nanoscale Science Research Centers (NRSCs) program. The support of the new administration, Congress, and DOE, as well as the advocacy of the DOE user facility community, is very gratefully acknowledged.

Stephen Streiffer

I am also very happy to report that the CNM will receive money from the American Recovery and Reinvestment Act that will allow us to expand our user program portfolio. These funds will be used for five capabilites: expansion of our computer cluster to triple its capacity; a cleanroom PECVD system for deposition of oxides and nitrides; upgrade of the CNM’s NSOM for significantly faster data acquisition and new imaging methods; a temperature stage and sample handler for the X-ray nanoprobe; and a two-color near-infrared transient absorption and emission spectrometer. These will nicely supplement other new equipment that the CNM is already in the process of acquiring, including a CVD system for deposition of carbon nanotubes, and a field-emission TEM.

While state-of-the-art capabilities such as those above are essential, the CNM’s identity is ultimately created and defined by our staff. Please join me in welcoming our most recent suite of new hires – David Czaplewski and Alexandra Imre (transitioning from her postdoctoral appointment to a full-time staff position) in the Nanofabrication and Devices group, Stuart Feinberg for additional ESH support, and Peter Fuez from Argonne’s Advanced Photon Source, who will be part of the X-ray nanoprobe team that is jointly staffed by the APS and CNM. We are also pleased to announce that Eric Isaacs, former CNM Director, has assumed his new role as Director of Argonne National Laboratory.

Finally, DOE just hosted its first NSRC Contractors’ Meeting, June 3-5, 2009. Staff and user representatives from each of the five centers gathered to discuss their research, providing an excellent opportunity for cross-fertilization across the NSRC program. We expect this to be a triennial event and look forward to the interactions among the NSRCs that this meeting has helped to nucleate.

Please read on for more news about the CNM, and I look forward to seeing you here at Argonne!

-- Stephen Streiffer, Interim Director

Platinum catalyst

LSM 510 META Laser Scanning Microscope

Conventional multifluorescence microscopy reaches its limit when emission signals of the dyes overlap. The CNM’s LSM 510 META solves this problem and creates brilliant images with rich information content. The design implements the confocal principle in a unique way, allowing multifluorescence images to be collected without compromising resolution and efficiency. For excitation of fluorescent dyes and fluorescent proteins, the instrument has different lasers emitting a number of lines in the ultraviolet and visible spectral ranges. The system is also equipped to use direct or fiber-coupled tunable short-pulse lasers for multiphoton excitation.

The distinctive features of this instrument include:

  • Emission fingerprinting
  • Online fingerprinting
  • Dynamic spectral analysis
  • FRET and FRAP measurements to track biological function
  • Physiology software
  • Quantitative colocalization
  • Multitracking – metatracking
  • Three-dimensional visualization
  • Multifluorescence

Contact Dr. Tijana Rajh, Leader of the Nanobio Interfaces Group, for information regarding this exceptional capability for your potential user science research.
