Fabrication and optical properties of nanoscale arrays of Au and Pd in polymers

Atre S.V., Bhowmik S., Valmikanathan O.P., Ostroverkhova O., Oregon Nanoscience & Microtechnologies Institute, US

We report the fabrication of regular repeat structures of Au and Pd square islands embedded in polymethyl methacrylate (PMMA) and polycarbonate (PC). Using focussed ion beam (FIB), square islands were machined over a 5 micron [...]

Nanotechnology for Building Security

Elvin G., Green Technology Forum, US

Despite increased vigilance and annual federal anti-terrorism spending in excess of $55 billion, building security remains a major concern for most Americans. For those working in large governmental or institutional buildings, fears are particularly acute. [...]

Novel Reactor Utilizing Selective Heating Catalytic Nanoparticles for Low-Temperature Growth of Carbon Nanotubes

Vasenkov A.V., Kolobov V.V., Carnahan D., CFD Research Corporation, US

Chemical Vapor Deposition (CVD) of carbon nanotubes (CNTs) and carbon nanofibers (CNFs) is a catalytically controlled synthesis requiring catalyst temperatures in excess of 700°C. The CVD synthesis is typically accompanied by significant substrate heating which [...]
