Improved Nanoreinforced Composite Material Bonds with Potential Sensing Capabilities

Starikov D., Price A., Glenn T., Attia F., Fischer M., Bokadoum M., Bensaoula A., Integrated Micro Sensors Inc., US

Dramatic increase in the bond strength of composite/adhesive interfaces of nano reinforced composite material joints and structures has been achieved using laser-assisted fabrication of Micro Column Arrays (MCA) on the surface of the two materials [...]

Electrical Properties of Functionalized Silicon Nanoparticles

Hartner S., Gupta A., Wiggers H., University Duisburg-Essen, DE

Phosphorous-doped as well as undoped Si-NPs with a mean particle diameter of about 50 nm were synthesized in a microwave plasma. The natural oxide was removed by etching the particles with hydrofluoric acid. In order [...]

Understanding Conduction Mechanisms in Nano-Structures

Gehman Jr V.H., Long K.J., Santiago F., Boulais K.A., Rayms-Keller A.N., Naval Surface Warfare Center, Dahlgren Division, US

Many technologies require the understanding of conduction and electrical transport mechanisms through nanostructures. Previous research has revealed unusual and enhanced conduction properties in pores whose width is significantly less than 1 m over a range [...]
