- Description
- NAICS Code: 541711 EPA is investigating the fate and transport of engineered nanomaterials (ENM) in air. The EPA seeks to develop a model to predict how ENM will behave in the atmosphere, in order to assess fate and transport. The model will be used to estimate the spatial distribution ofENM near their source as well as the size distribution of the ENM after it has interacted with a typical ambient aerosol. Two parameters which are critical to predicting the atmospheric fate of nanoparticles are (1) the deposition velocity (vd) and (2) the coagulation or agglomeration efficiency (K12). For ENMs smaller than ~ 50 nm diameter, the deposition velocity is expected to be dominated by Brownian diffusion. Both vd and K12 have been both modeled and measured for spherical particles (Figures 19.3 and 12.5, Seinfeld and Pandis, 1998). Current nano-research initiatives within the Agency are focused on three separate ENMs: CeO2, nanosilver, and nano-TiO2. EPA?s research will include determination of the fate and transport of engineered nano-CeO2 which is currently used in Europe in diesel fuel additives in order to reduce soot emissions. Combusted nano-CeO-2 particles are expected to be released into the atmosphere attached to larger diesel soot particles (Jung et al., 2005). In this regard, the working hypothesis is that nanoparticles created with the cerium additive will have different characteristics than those generated without the additive. The EPA thus seeks to measure the deposition velocity and coagulation efficiency for soot particles generated from the combustion of CeO2-doped and undoped diesel fuel. Period of performance will be 12 months from award of the purchase order. A Request for Quotation (RFQ) with complete information will be posted on the EPA's website in approximately 15 days at the following address: http://www.epa.gov/oam/rtp_cmd/ Responses to the RFQ will be due approximately 30 days after issuance of the RFQ. Hard copies of the RFQ will not be available. Offerors must submit both a technical proposal and a price proposal. The price proposal must show a complete breakout of costs. The technical proposal must include responses to the Technical Evaluation Criteria, which will be posted with the RFQ. All future information about this acquisition, including amendments (if any), will also be distributed solely through the EPA's web site. Interested parties are responsible for monitoring this site to ensure that they have the most up-to-date information about this acquisition. Telephone and FAX requests for this information will not be honored. Potential offerors should hold any technical questions until they have had a chance to completely review the RFQ.
