21. Melting and Chemical Behaviors of Isothermally-Crystallized Gamma-Irradiated Syndiotactic Polystyrene
Tinh T. Nguyen, Sanboh Lee, Kuo L. Chien
Melting and chemical behaviors of isothermally-crystallized gamma-irradiated sPS have been investigated using differential scanning calorimetry, FTIR, and X-ray diffraction techniques. Amorphous sPS samples were subjected to gamma radiation in vacuum ...
22. Adhesion Loss and Corrosion-induced Delamination of Fusion-Bonded Epoxy Coated Steel in Alkaline Electrolytes
Tinh T. Nguyen, Jonathan W. (Jonathan W.) Martin
Fusion-bonded epoxy is used extensively for increasing the service life of steel-reinforced concrete structures. However, field observations have reported premature corrosion of fusion bonded epoxy-coated reinforcing bars used in marine concrete envi ...
23. Linking Accelerated Laboratory Test with Outdoor Performance Results for a Model Epoxy
Xiaohong Gu, Deborah L Stanley, Walter Eric Byrd, Brian Dickens, Iliana Vaca-Trigo, William Meeker, Tinh T. Nguyen, Jonathan W. (Jonathan W.) Martin
Laboratory and field exposure results have been successfully linked for a
model epoxy coating system. The mathematical model used in making this
linkage only assumed that the total effective dosage, additivity law, and reciprocity
laws were valid. ...
24. NCO-Functionalized Nanoclays for Polyurethane Composite Coatings
Bastien T. Pellegrin, Xiaohong Gu, Joannie W Chin, Tinh T. Nguyen
25. Subsurface mapping of nanofiller dispersion in polymeric coatings by quantitative electric force microscopy
Minhua Zhao, Juntao Wu, Bastien T. Pellegrin, Xiaohong Gu, Tinh T. Nguyen
26. Water Soluble DNA-Wrapped Single-Walled Carbon Nanotube/Quantum Dot Complexes
Zhenping Zhou, Hyeong G. Kang, Jeffrey A Fagan, Alexander J. Shapiro, Matthew Lawrence Clarke, Jeeseong Hwang, Tinh T. Nguyen
27. Role of Interfacial Water in the Adhesion Loss of Polymer/Substrate Systems and Composites
Tinh T. Nguyen, Joannie W Chin, E Byrd, David Alshed, Cyril Clerici, Jonathan W. (Jonathan W.) Martin
Water at the polymer/substrate interface in coatings, adhesives, and fiber-reinforced polymer composites is often the main cause of adhesion loss in these systems. Using experimental data measured in this study, we critically assess the role of inter ...
28. Covalent Functionalization of Carbon Nanotubes With Diisocyanate for Polyurethane Nanocomposites
Aline Granier, Tinh T. Nguyen, Naomi Eidelman, Jonathan W. (Jonathan W.) Martin
Carbon nanotubes (CNTs) have a wide range of potential applications due to their unique mechanical properties, high aspect ratios, and electronics structures. Many of these applications require good dispersion and chemical reactivity of CNTs in polym ...
29. Load-Displacement Relations for Nanoindentation of Viscoelastic Materials
Chien-Kuo Liu, S H Lee, Li Piin Sung, Tinh T. Nguyen
A model based on the Burgers viscoelastic concept has been developed to describe the nanoindentation behaviors of polymeric materials. An analytical solution of displacement at the indenter tip has been derived based on the analog of the governing eq ...
30. Chemical and Physical Characterization of Poly(p-phenylene benzobisoxazole) Fibers Used in Body Armor
NIST Interagency/Internal Report (NISTIR)
Joannie W Chin, E Byrd, Amanda Lattam Forster, Xiaohong Gu, Tinh T. Nguyen, Kirk D Rice, Walter J. Rossiter, S J Scierka, John R Sieber, Paul E Stutzman, Li Piin Sung
Problems with the performance and durability of body armor based on poly(p-phenylene benzobisoxazole (PBO) fiber became apparent in the summer of 2003, when PBO-based body armor that was less than 8 months was penetrated by a bullet. Mechanical te ...
