Comparative Study Of Effect Of Various Reducing Agents On Size And Shapes Of Gold Nanoparticles

Kumar A., Dhawan N., Stanford University, US

Nanoparticles have attracted considerable interest because of their unique optical, electromagnetic and catalytic properties that differ from bulk ones. The origin of these properties is their large surface to volume ratio and from the coherent [...]

The real-time, simultaneous analysis of nanoparticle size, zeta potential, count, asymmetry and fluorescence

Carr R., Hole P., Malloy A., Smith J., Weld A., Warren J., NanoSight Ltd, UK

A new nanoparticle sizing and characterisation technique is described which allows nanoparticles in a suspension to be individually but simultaneously detected and analysed in real time using a low cost instrument. Nanoparticles of all types [...]

The Innitial Reverse-Bias Injecting P+-N Junction Mode in P+-N-P+- Structures with Punch-Through

Mats I., Diatex, Selected Texno-Fix, CA

The Volt-Ampere Characteristics (VAC)s of P+NP+-structures in the schemes with floating base and short-cut p+-n junction (emitter) in punch-through modes were calculated before. It is important to research a behavior for similar structures but with [...]

Growth of Si Nanowires on Nano Catalyst Corners

Wang C., Malladi K., Madou M., University of California Irvine, US

One dimensional structure with nanometer diameters, such as Si nanowires, have great potential for understanding and testing fundamental concepts about the roles of dimensionality in optical, electrical and mechanical properties and for applications ranging from [...]
