Mechanical and Thermal Stability of Carbon Nanotube Junctions

Shi S.Q., Liu W.C., Meng F.Y., The Hong Kong Polytechnic University, CN

Mechanical and thermal stability of carbon nanotube junctions was studied using molecular dynamics simulation method. Junctions made from armchair and zigzag thin carbon nanotubes were first formed by thermal welding process, then tested under 1D [...]

Incorporation of Nanoparticles into Soy-based Polyurethane Foam

Liang K., Mao A., Shi S.Q., Mississippi State University, US

Nanotechnology is one of the most effective ways to develop advanced materials. Nanophases including nanoclay, Polyhedral Oligomeric Silsequioxane (POSS), organic and inorganic nanofibers are often used to be incorporated into polymer resin systems to improve [...]

Comparative Study of Fabrication Patterns of a Ferroelectric Polymer P(VDF-TrFE) on Gold Thin Film and Gold Ball via Dip-pen Nanolithography

Tang Q., Shi S.Q., Zhou L.M., Xu C.H., The Hong Kong Polytechnic University, CN

An AFM-based nanolithography, dip-pen nanolithography is becoming a promising nanotechnology since its invention.However, there exists much uncertaintied in DPN process.Much research work are required to do in order to make it as a competitive nanolithography [...]

Synthesis of Antimony Oxide Nanoparticles by Thermal Oxidation

Xu C.H., Shi S.Q., Tang Q., The Hong Kong Polytechnic University, HK

Antimony (Sb) oxide can be used as catalyst, retardant, fining agent, and optical material. Recently, hydrous Sb oxide was found to have high proton conductivity, which is likely to be a promising humidity-sensing material. Oxide [...]

Effects of Stone-Wales Defect on Adsorption & Insertion Capacity of Nanotubes

Zhou L.G., Meng F.Y., Shi S.Q., Hong Kong Polytechnic University, CN

As more experimental results become available and theoretical investigations get deeper, carbon nanotube (CNT) is found to be not as perfect as it seems. Due to this reason, the presence and roles of defects in [...]
