The Center for Nanophase Materials Sciences (CNMS) at Oak Ridge National Laboratory (ORNL) is soliciting proposals for user-initiated nanoscience research that will make effective use of CNMS facilities and staff expertise. The CNMS nanoscience research program provides users with access to a broad range of capabilities for nanomaterials design, synthesis, characterization, and theory/modeling/simulation in order to carry out studies that will significantly advance our understanding of nanoscale phenomena and develop functional nanomaterials systems. Access is provided at no cost to users for research that is in the public domain and intended for publication in the open literature.
Scientifically high-impact proposals are sought that take advantage of any of the CNMS research capabilities listed below. In particular, prospective users are encouraged to submit proposals that utilize and exploit synergies of research capabilities in two or more of the areas listed below, and proposers of experimental nanoscience research are encouraged to request theory/modeling/simulation collaborations as appropriate.

Opportunity to request beamtime for Neutron Scattering
The CNMS is cooperating with ORNL's neutron scattering facilities to allow users to request neutron beamtime within a CNMS user proposal, provided that the main part of the proposed work would be carried out at CNMS. To request beamtime at one of ORNL’s neutron facilities, CNMS users should attach the 2-page Neutron Scattering appendix with their CNMS proposal submission. The beamtime request will be reviewed concurrently with the CNMS proposal review. CNMS access for any proposal will still be based entirely on the CNMS’s standard peer-review process. A CNMS user whose beamtime request is approved will receive that beamtime during late CY2016 to early 2017. Note that if the primary thrust of the proposal is to obtain access to neutron scattering, prospective users must submit the proposal directly to the neutron scattering user program.
The CNMS offers two types of sample design and synthesis capabilities specifically to enable forefront neutron scattering investigations:
- Organic and polymer synthesis capabilities are available to prepare deuterated small molecules, monomers, and polymers.
- Design and synthesis capabilities are available for multilayered oxide heterostructures grown with atomic-layer control to adequate thicknesses.
In addition, other synthetic capabilities within CNMS can create samples appropriate for neutron scattering experiments as designed by users.
The CNMS website provides detailed descriptions of specific CNMS Research Capabilities that are offered to users, and this list of capabilities is duplicated in checklist form on the downloadable CNMS User Proposal Form. Prospective users are invited and strongly encouraged to contact CNMS staff members in the respective research areas to discuss their proposal ideas and learn more about the specific capabilities of interest to them.
The deadline for submission of user research proposals is October 21, 2015. Please review the Guidelines for Submission of a CNMS User Research Proposal (below) and the Instructions for Submitting a Proposal. Approved projects will be granted access to CNMS facilities during the period February 1, 2016 through January 31, 2017.
The CNMS is a highly collaborative national user research facility dedicated to the synthesis, characterization, theory/modeling/simulation, and design of nanoscale materials, and their integration into functional systems. The CNMS cannot provide direct research funding to users.
Guidelines for Submission of a CNMS User Research Proposal
Each user proposal must describe clearly and
specifically which part of the work is to be done using CNMS facilities: What CNMS tools and expertise will be needed to carry out which steps and on what timeline? Each user proposal must also clearly define the expected outcomes from the CNMS component: What are the targets or milestones that the CNMS contribution must meet in order for the overall research project to succeed? Please keep in mind that you are proposing a specific user project; describe the overall research program only so far as is necessary to establish the context and impact of the user proposal.
See Tips for Writing a Competitive User Proposal.
- Priority must be given to proposals that lie within current CNMS Capabilities. Proposals that require capabilities from more than one area are encouraged, as are requests for theory/modeling/simulation support for experimental projects.
- Proposals will be reviewed by selected members of the CNMS Proposal Review Committee using evaluation criteria adopted by the IUPAP in its recommendations on the operation of user facilities. Please see the DOE NSRC Evaluation Criteria and Process and Evaluation Criteria for CNMS Research Proposals.
- Prospective users are encouraged to contact one of the staff members listed for each set of related research capabilities to discuss the suitability of any particular CNMS capability for the proposed research. General questions about the proposal process can be directed to the CNMS User Program Manager, Dr. Tony Haynes.
