1. Preparation of silver nanoparticle loaded cotton threads to facilitate measurement development
for textile applications
Special Publication (NIST SP)
Justin M Gorham, Karen E Murphy, Jingyu Liu, Dimitri Tselenchuk, Gheorghe Stan, Thao Minh Nguyen, Richard D Holbrook, Michael R Winchester, Robert Francis Cook, Robert MacCuspie, Vincent A Hackley
This NIST special publication (SP) is one in a series of NIST SPs that address research needs
articulated in the National Nanotechnology Initiative (NNI) Environmental, Health, and Safety
Research Strategy published in 2011 . This ...
2. A pilot interlaboratory comparison of protocols that simulate aging of nanocomposites and detect released fragments
Wendel Wohlleben, Deborah L Stanley, Justin M Gorham, Li Piin Sung, Tinh Nguyen
The safe use of nanocomposites depends, in part, on a good understanding of the fate of nanofillers throughout the nanocomposite,s lifecycle. Various modifications of ISO weathering protocols have been proposed to assess what is released and at which ...
3. Multi-method analysis of multiwall carbon nanotube polymer nanocomposite samples after photodegradation
Elijah J Petersen, Thomas Fung Lam, Justin M Gorham, Keana C K Scott, Christian John Long, Renu Sharma, Li Piin Sung, James Alexander Liddle, Tinh Nguyen
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 ...
4. Thermochromic Phase Transitions in VO2-based Thin Films for Energy-Saving Applications
Sara Cordero Barron, Justin M Gorham, Martin L Green
The thermochromic transition in vanadium dioxide has potential application as a smart energy-saving window coating, but the temperature of the transition must be depressed from 68°C to Earth ambient temperatures by the incorporation of transition met ...
5. A Quantitative Study of Nanoparticle Release from Nanocoatings Exposed to UV Radiation
Li Piin Sung, Deborah L Stanley, Justin M Gorham, Savelas A Rabb, Xiaohong Gu, Lee Lijian Yu, Tinh Nguyen
Nanoparticles are increasingly used in polymer coatings (i.e., nanocoatings) to improve multiple properties of traditional coatings such as mechanical, electrical, gas barrier, and UV resistance. These high performance nanocoatings are often used in ...
6. Storage Wars: How citrate capped silver nanoparticle suspensions are affected by not-so-trivial decisions
Justin M Gorham, Anne B Rohlfing, Katrice A Lippa, Robert I. MacCuspie, Amy Hemmati, Richard D Holbrook
A critical but often overlooked component of silver nanoparticle (AgNPs) suspensions involves their behavior following short- and long-term storage. The current study investigates the integrity of citrate-capped AgNP suspensions, nominally 20 nm in ...
7. Highly Stable Positively Charged Dendron-Encapsulated Gold Nanoparticles
Tae Joon Cho, Robert I. MacCuspie, Julien C. Gigault, Justin M Gorham, John T Elliott, Vincent A Hackley
We report the development of a novel cationic dendron (TAG1-PCD) and a positively charged gold nanoparticle-dendron conjugate (PCD-AuNP). TAG1-PCD was designed by considering the reactivity, hydrophilicity, and cationic nature that is required to yie ...
8. Controlled Formation and Characterization of Dithiothreitol-Conjugated Gold Nanoparticle Clusters
De-Hao D. Tsai, Tae Joon Cho, Frank W DelRio, Justin M Gorham, Jiwen Zheng, Jiaojie Tan, Michael Russel Zachariah, Vincent A Hackley
We report a systematic study of the controlled formation of discrete-size gold nanoparticle clusters (GNCs) by interaction with the reducing agent dithiothreitol (DTT). Asymmetric-flow field flow fractionation and electrospray differential mobility a ...
9. Role of salt on adhesion of an epoxy/aluminium (oxide) interface in aqueous environments
Christopher C White, Kar T. Tan, Donald Lee Hunston, Justin M Gorham, Aaron M Forster, Vogt D Bryan
The durability of adhesive joints in hostile environments is a major area of concern in structural adhesive bonding. Therefore, understanding the mechanics and mechanisms of degradation of adhesive joints is a key factor for more extensive use in fut ...
10. Development of a conceptual framework for evaluation of nanomaterials release from nanocomposites: environmental and toxicological implications
Jame Ging, Raul Tejerina-Anton, Girish Ramakrishnan, Mark Nielsen, Kyle Murphy, Justin M Gorham, Tinh Nguyen, Alexander Orlov
Despite the fact that nanomaterials are considered potentially hazardous in a freely dispersed form, they are often considered safe when encapsulated into a polymer matrix. However, systematic research to confirm the abovementioned paradigm is lackin ...
