4. Methods for the Measurement of Release of MWCNTs from MWCNT-Polymer Composites
Published: 9/18/2014
Authors: Debra L Kaiser, Aleksandr B. Stefaniak, Keana C K Scott, Tinh Nguyen, Jurg Schutz
Abstract: Multi-wall carbon nanotube (MWCNT)/polymer composites hold great promise as advanced materials for consumer and industrial applications. Throughout the life cycle of these composites, there is opportunity for release of particles that may contain MWC ...

5. Multi-method analysis of multiwall carbon nanotube polymer nanocomposite samples after photodegradation
Published: 6/16/2014
Authors: Elijah J Petersen, Thomas F. Lam, Justin M Gorham, Keana C K Scott, Christian John Long, Renu Sharma, Li Piin Sung, James Alexander Liddle, Tinh Nguyen
Abstract: Nanomaterials can be used as nanofillers to enhance the properties of polymeric materials. However, the effect of weathering on nanocomposites and the potential for nanomaterial release is not yet well understood. Multiple analytical methods are ne ...

6. Recent Advances in Focused Ion Beam Technology and Applications
Published: 4/11/2014
Authors: Nabil Bassim, Keana C K Scott, Lucille A Giannuzzi
Abstract: Focused ion beam (FIB) microscopes are extremely versatile and powerful instruments for materials research. These microscopes, when coupled in a system with a scanning electron microscope (SEM), offer the opportunity for novel sample imaging, secti ...

7. Effects of nanoparticle size and charge on interactions with self-assembled collagen
Published: 3/1/2014
Authors: Dongbo Wang, Jing (Jing) Ye, Steven D Hudson, Keana C K Scott, Sheng Lin-Gibson
Abstract: Recent insights into bone formation have suggested that the critical first step to the biomineralization process is the integration of small (nanometer dimension) mineral clusters into collagen fibers. Such behavior is of intrinsic interest for the a ...

8. Impact of UV Irradiation on the Surface Chemistry and Structure of Multiwall Carbon Nanotube Epoxy Nanocomposites
Published: 12/6/2013
Authors: Elijah J Petersen, Thomas F. Lam, Justin M Gorham, Keana C K Scott, Christian John Long, Deborah L Stanley, Renu Sharma, James Alexander Liddle, Tinh Nguyen
Abstract: One of the most promising applications of nanomaterials is as nanofillers to enhance the properties of polymeric materials. However, the effect of nanofillers on polymers subject to typical environmental stresses, such as ultraviolet (UV) radiation, ...

9. Detection and Speciation of Brominated Flame Retardants in Consumer Products and Household Dust
Published: 3/27/2012
Authors: Richard D Holbrook, Jeffrey M. Davis, Keana C K Scott, Christopher W Szakal
Abstract: The ubiquitous presence of brominated flame retardants in humans, biota, and the environment has caused concerns about their toxicity, transformations, and persistence. Polymeric materials, which often are intercalated with include brominated flame ...

10. Minimizing damage during FIB-TEM sample preparation of soft materials
Published: 11/17/2011
Authors: Nabil Bassim, Bradley De Gregorio, A. D. Kilcoyne, Keana C K Scott, Tsngming Chou, S. Wirick, George Cody, Rhonda Stroud
Abstract: Although focused ion beam (FIB) microscopy has been used successfully for milling patterns and creating ultra-thin transmission electron microscopy (TEM) sections of polymers and other soft materials, little has been documented regarding FIB-induced ...
