The Spring 2012 CINT Call for Proposals is closed. The proposals are currently being reviewed. Notificiations will go out in June, with accepted proposals able to start in July.

The database is currently open for Rapid Access Proposals. These should be limited in scope and have strong justification for expedited processing.

If you have recently been to CINT to work on your project, or are just finishing a project, please complete our CINT User Satisfaction Survey.

UEC Elections

CINT is currently holding an election of new members to the CINT Users Executive Committee (UEC). All users are invited to vote for no more than three UEC General Candidates and one Student/Postdoc Candidate. The election will close on Wednesday, June 6th. Vote now!

 

Announcing the 2012 CINT User Conference!

CINT will be holding the 2012 CINT User Conference on September 18-20, 2012 in Albuquerque, New Mexico. There will be three concurrent symposia:

  • Nanoparticle Biocompatibility
  • NanoMechanics of Top Down and Bottom Up Nanonstructures
  • Nanowires

Following the workshop, on Sept 20-21, there will be a satellite meeting on nanophotonics. More details coming soon. Registration for both events will be available the end of June.

 

Joint NSRC Workshop on Nanoparticle Science

You are cordially invited to participate in a workshop on nanoparticle science. The primary aim of the workshop is to bring together scientists from the five DOE Office of Science Nanoscale Science Research Centers to discuss recent developments in nanoparticle synthesis, characterization, modeling, and assembly for explorations of functionality in clean energy and other applications. The meeting will be held at the Center for Nanoscale Materials, Argonne National Laboratory, on November 5-6, 2012. Please see the flyer for more information.

 

User Newsletter

Please check out the first edition of our user newsletter, the Integrated Circuit. It is full of announcements, science highlights and other news.

 

Awards and honors

CINT Scientist and CINT User awarded by the Minerals, Metals & Materials Society (TMS)
The Minerals, Metals & Materials Society (TMS) has selected CINT User John Carpenter of LANL's Metallurgy and the Center for Integrated Nanotechnologies groups and CINT Scientist Nathan Mara of the Lab's Center for Integrated Nanotechnologies group to receive a 2012 TMS Young Leader Professional Development Award. The Society created the annual award to enhance the professional development of dynamic young people from the five technical divisions of TMS. Awardees participate in Society activities, attend TMS conferences, network with Society members and leaders, receive mentoring from TMS division leaders, and serve as judges for division-sponsored student events at the TMS Annual Meeting. Carpenter will receive the award from the TMS Extraction and Processing Division. Mara will receive the award from the Materials Processing and Manufacturing Division.

Please see the LANL press release for more information.

Jan 2012 Publication from CINT Users at U Penn - Nanorod Assemblies in Polymer Films and Their Dispersion- Dependent Optical Properties

nanorod assemblies

Optical absorption due to surface plasmon resonances in ensembles of gold nanorods (Au NRs) depends strongly on the nanorod separation and orientation. Here, we study the dispersion of polystyrene-functionalized Au NRs in polystyrene (PS) thin films using UV−visible (UV−vis) spectroscopy and transmission electron microscopy (TEM) and find that Au NRs are dispersed for brush chain lengths that exceed the PS matrix chain length and are aggregated otherwise. Monte Carlo simulations using parameters from classical density functional theory (DFT) calculations indicate that this behavior is due to substantial depletion−attraction forces for brush chain lengths that are much smaller than the PS matrix chain length. Both UV−vis measurements and discrete dipole approximation (DDA) calculations confirm that optical absorption is a facile method to determine nanorod morphology in nanocomposite films (i.e., aggregation or dispersion). Futhermore, a dispersion map is constructed showing the conditions required for nanorod dispersion and, correspondingly, the optical absorption properties of Au NR:PS nanocomposites. Using this information, optically active materials with tunable morphologies can be fabricated and routinely characterized using optical spectroscopic methods.

Full article was published in the January 2012 ACS Macro Letters.
