Carbon nano-rope films were fabricated on the Ni-catalysed Si substrate by microwave plasma-enhanced chemical vapor deposition employing a mixture of acetylene and hydrogen. These nano-ropes were in the form of self-assembled, stranded carbon nano-fi

C2 radical density in a conventional microwave plasma-enhanced chemical vapor deposition (MWPCVD) with CH4/H2 mixture was measured using absorption spectroscopy. At the typical growth conditions for MWPCVD used for nanocrystalline diamond formation,

Objectives The developments in combinatorial chemistry have led to a rapid increase in drug design and discovery and, ultimately, the production of many potential molecules that require evaluation. Hence, there has been much interest in the use of ma

Nanostructuring materials can radically change their properties. Two interesting examples highlighted here are nanoscale porosity inducing biodegradability, and nanoscale confinement affecting the physical form of an entrapped drug. Mesoporous silico

The first studies are reported on the characteristics of ultra-violet transmissive mode, CVD diamond photocathodes, in which photoelectrons are emitted from a diamond membrane via the opposite interface from that of the incident radiation. For membra

Variations in photoyield at 186 and 252 nm have been measured from CVD diamond photocathode materials grown on silicon substrates, as the growth conditions and surface termination were changed. The photoyield increased rapidly for short growth times

The influence of differing chemical environments on the surface conductive properties of chemical vapor deposition (CVD) diamond films has been explored. Only small changes in the insulating character of the diamond surface is observed when surfaces

The quantum efficiency and chemical stability of CVD diamond photocathodes has been examined. As-grown or microwave plasma hydrogenated boron-doped diamond films display a quantum photoyield of approximately 0.05% at 190 nm, which degrades gradually
