Estimate effective interaction potentials from the static structure factor in pure fluids and nanocolloids

Oprisan A., Oprisan S.A., Oprisan A., Oprisan S.A., Teklu A., Hegseth J., College of Charleston, US

The direct visualization and analysis of critical fluctuations in pure fluids in microgravity, and concentration-driven interface fluctuations in nanocolloids provide invaluable information about cooperative phenomena and the role played by fluctuations in mixing, phase separation, [...]

Mechanical Characteriztion of XD-Grade Carbon Nanotube/Epon 862 Processed by Dual Phase Dispersion Technique

Hossain M.K., Okoro C., Hosur M., Jeelani S., Rangari V., Tuskegee University, US

In this research, a dual-phase dispersion method is studied combining a high intensity ultrasonic liquid processor with a three roll milling technique. Xd-grade carbon nanotubes (xd-CNTs) were infused into Epon 862 epoxy and then mixed [...]

Durability Study of Nanophased Jute-Based Green Composites

Hossain M.K., Dewan M.W., Hosur M., Jeelani S., Tuskegee University, US

Jute fiber reinforced biopol biocomposites with and without nanoclay were manufactured using treated and untreated jute fibers by a compression molding process and their durability study was performed using standard moisture absorption and flexure tests [...]

Surface Modification of Iron Oxide (Fe3O4) Micro- and Nano-particles with Stimuli Responsive Polymers

Vasquez E.S., Nicholson W.B., Walters K.B., Mississippi State University, US

In this work, the synthesis of stimuli responsive polymer brushes was carried out using surface-initiated atom transfer radical polymerization (ATRP) on iron oxide (Fe3O4) micro- and nano-particles. Bare Fe3O4 nanoparticles (20 nm nom. d(H)) were [...]

Fabrication of nanostructured microworms for sensor applications

Yagüe J.L., Dubach J.M., Ozaydin-Ince G., Clark H.A., Gleason K.K., Massachusetts Institute of Technology, US

A novel method to create in vivo sensors for multiple types of ions and molecules is presented. Using initiated Chemical Vapor Deposition (iCVD), a gentle process which preserves functional pendant groups and enables conformal coatings, [...]

Computer Simulation of Graphene-Metal Composite Induced by Radiation

Ilyin A.M., Beall G.W., Texas State University, US

Characterization of Nanoparticle Release from Polymer Nanocomposites Due to Fire

Uddin N.M., Nyden M.R., National Institute of Standards and Technology, US

Studies are being conducted to understand the potential hazards associated with burning materials containing carbon nanotubes (CNTs) and nanofibers (CNFs) either in the process of incineration or in accidental fires. Some of the important questions [...]

Fabrication and Testing of Three-Dimensionally Reinforced Carbon Nanotube Based Laminated Nanocomposites

Askari D., Ghasemi-Nejhad M.N., The University of Texas at Brownsville, US

Carbon nanotubes (CNTs) can be used for the reinforcement of polymers to create novel nanotube based nanocomposites with tunable properties and multifunctional behaviors. Chemical vapor deposition technique is employed to grow vertically aligned high density [...]

Enhancing mechanical properties of epoxy resin while reducing viscosity using “liquid nano-reinforcement”

Zhong K., Washington State University, US

Graphitic carbon nanofibers (GNFs) were first made into a “liquid nano-reinforcement” (LNR) that is composed of reactive nanofibers (r-GNFs) and an epoxy diluent through chemically reacting the functionalized GNFs with the diluents. Due to the [...]

Polymer Nanocomposites from Functionalized Polyolefins

Paul D.R., University of Texas at Austin, US

Polymer-layered silicate nanocomposites formed from the organically modified clay mineral montmorillonite and related materials have attracted a great deal of technological and scientific interest in the past decade. These composites offer the promise of greatly [...]
