Optical vortex trap for resonant confinement of metal nanoparticles [PDF]
, 2008 The confinement and controlled movement of metal nanoparticles and nanorods is an emergent area within optical micromanipulation. In this letter we experimentally realise a novel trapping geometry near the plasmon resonance using an annular light field ...

Research progress on metal particle contamination in GIS/GIL
CSEE Journal of Power and Energy Systems, 2019 The metal particle contamination in gas-insulated switchgear (GIS) or gas-insulated transmission line (GIL) is an important factor leading to the decline of insulation performance.

Superconductivity in Ultrasmall Metallic Particles [PDF]
, 2000 Chapter 25 Recent single electron transport experiments in nanometer size samples renewed the question about the lower limits of the size of superconductors, and the crossover from superconducting to normal state. In order to give answers to these questions, a pairing Hamiltonian for fixed number of particles is studied including the degeneracy of ...
