Electron Guiding through Insulating Nanocapillaries

Transmission of Hundred-keV Protons through Insulating Nanocapillaries: Charge-patch-assisted Specular Reflections

In this work, we measured the time evolution of the transmission features of 10-100 keV protons transmitted through nanocapillaries in a polycarbonate (PC) membrane. After reaching equilibrium, transmitted particles with an incident energy of 100 keV were located around the direction along the incident beam but not along the capillary axis, indicating that the transport mechanism of the 100 keV...

Controllable shrinking and shaping of glass nanocapillaries under electron irradiation.

The ability to reshape nanopores and observe their shrinkage under an electron microscope is a powerful and novel technique. It increases the sensitivity of the resistive pulse sensing and enables to detect very short and small molecules. However, this has not yet been shown for glass nanocapillaries. In contrast to their solid-state nanopore counterparts, nanocapillaries are cheap, easily fabr...

Exchange through nonmagnetic insulating matrix

Electrochemical Nonadiabatic Electron Transfer via Tunneling to Solution Species through Thin Insulating Films.

Described here is a semiquantitative theoretical treatment of the kinetics of outer sphere electrochemical reactions. The framework presented here, which is based on simple physical arguments, predicts heterogeneous rate constants consistent with previous experimental observations (k0 > 10 cm/s). This theory is applied to the analysis of voltammetry experiments involving ultramicroelectrodes mo...
