Resistance transfer standard which transfers Ohm value from quantum Hall resistance (QHR) to the reference standard of 10 kOhm and then to the standard of 100 kOhm

A scheme is proposed for a resistance transfer standard which transfers Ohm value from quantum Hall resistance (QHR) to the reference standard of 10 kOhm and then to the standard of 100 kOhm. Metrological and design considerations are discussed. A bridge-comparator scheme for mutual comparison of transfer standard resistors with uncertainty (0,01...0,02) ppm and calibration procedure for the resistance transfer standard are also proposed.

Keywords: resistance transfer standard, quantum Hall resistance (QHR), binary bridge-comparator, transfer standard calibration, transfer coefficient, comparison uncertainty, input and output resistances.

Probe Nanotechnology Assembling of Conductive Nanoparticles

The probe assembling of the conductive nanoparticles clusters in liquids was investigated by molecular dynamics. The slow diffusion and fast drift process stages of nanoparticles assembling were considered. In the drift stage dielectrophoretical force was calculated by the boundary element method that uses Green's functions. The probes with a large (100 nm) radius of the tip appear more preferably than probes with a small (10 nm) radius. The results open prospects for probe nanotechnology methods, nanomechanics and nanoflyuidics.

Keywords: probe nanotechnology, nanoparticle, dielectrophoresis, nanofluidics, molecular dynamics, Green's function.
