Physics applied to electrochemistry: Tunneling reactions

Physics Applied to Anaesthesia

Scanning tunneling microscopy applied to optical surfaces.

The technique of scanning tunneling microscopy has been applied to topographic mapping of two optical surfaces: a ruled grating replica and a diamond-turned gold mirror. We have demonstrated the ability of the scanning tunneling microscope to measure surface topography of a ruled-grating replica over an area of 2 microm x 2 microm. Furthermore, surface structure on a diamond-turned gold mirror ...

Magnetic tunneling applied to memory (invited)

Random access magnetoresistive memories have been designed using anisotropic magnetoresistive ~AMR! material and more recently giant magnetoresistive ~GMR! material. The thin films in these memories have low sheet resistivities ~about 10 V/sq!, resulting in cell resistances of 10 to 100 V at competitive areal densities. High sense currents of a mA or more are required to get signals on the orde...

Isotachophoresis applied to chemical reactions

This review discusses research developments and applications of isotachophoresis (ITP) to the initiation, control, and acceleration of chemical reactions, emphasizing reactions involving biomolecular reactants such as nucleic acids, proteins, and live cells. ITP is a versatile technique which requires no specific geometric design or material, and is compatible with a wide range of microfluidic ...

Applied Physics

A portable modular gas sensor for measuring the 13 C/ 12 C isotopic ratio in CO 2 with a precision of 0.8%o(±1σ) was developed for volcanic gas emission studies. This sensor employed a difference frequency generation (DFG)-based spectroscopic source operating at 4.35 µm (∼ 2300 cm −1) in combination with a dual-chamber gas absorption cell. Direct absorption spectroscopy using this specially des...
