Microcharacterization of Creep Behavior of Carbon Nanofiber Reinforced HDPE Nanocomposites using a Depth Sensing Method

Xu S., Liu T., Tangpong X.W., Akhatov I., Zhong W-H., North Dakota State University, US

Depth-sensing indentation at micro- and nano-scale levels is a useful tool for material characterization due to its simplicity. There are many well-established methods for determining local mechanical properties including elastic modulus, hardness, and fracture toughness [...]

Soybean meal nano scales resistant starch- model carbohydrates for encapsulation of bioactive compounds

Sivapragasam N., Petrović D., Thavarajaha P., Thavarajahc D., North Dakota State University, US

The research focus is on encapsulating materials like drugs and nutrients specifically for colon using resistant starch. As a representation a model system is developed by encapsulating glass bead and experimenting the suitability to be [...]

Transverse Elastic Modulus of Tobacco Mosaic Virus Superlattice

Wang H., Wang X., Wang H., Wang X., North Dakota State University, US

Tobacco mosaic virus (TMV) and TMV-derived materials have demonstrated their great potential in biomedical applications, where the mechanical property is one of the determining factors for their proper functionalities and structural integrity. Recently, it has [...]

Electrospun Carbon nanofibers-Based Supercapacitors

Zhou Z.P., North Dakota State University, US

For efficient use of conductive polymers, such as Polyaniline (PANI) and Polypyrrole (PPy), in pseudocapacitors and other electrochemical applications, the poor conductivity of the conductive polymers is a major problem. To solve the problem, here [...]

Nanomechanical characterization of UV curable hyperbranched polymers

Kim J., Chen Z., Chisholm B., Patel S., North Dakota State University, US

Hyperbranched polymers were explored to develop UV-curable, protective coatings for aluminum 2024-T3 and their viscoelastic and mechanical properties were characterized using nanoindentation techniques. The coating system consists of a hyperbranched polyester acrylate (CN2300, Sartomer Inc), [...]

Quick “easy?!” determination of the diameter of nanocapillaries

Lutfurakhmanov A., Sailer R., Akhatov I., Schulz D.L., North Dakota State University, US

Precise measurements of the inner diameter (ID) of nanocapillaries are of interest to many areas of study due to the high sensitivity of gas and liquid flows with respect to the radius of the capillary. [...]

Application of Robotic Combinatorial Methods for the Synthesis and Screening of Hybrid Organic-Inorganic Marine Coatings

Christianson D.A., Chisholm B.J., Stafslien S.J., Gallagher-Lein C., Bahr J.A., North Dakota State University, US

A combinatorial robotic workflow has been developed and implemented at North Dakota State University for the synthesis and screening of marine coatings. Several traditional tools and methods for characterizing polymers and coatings have been customized [...]
