Flow-injection amperometry at microfabricated silicon-based μ-liquid–liquid interface arrays

Carrier injection at silicide/silicon interfaces in nanowire based-nanocontacts

Stm-based Charge-injection Spectroscopy at the Organic/metal Interface

We have developed a new method for characterizing the electronic properties of organic thin films and interfaces for electronic device applications. In this scanning tunneling microscope (STM)-based technique, distance versus potential curves are collected at constant tunneling current. Here the STM feedback mechanism causes the tip to penetrate the organic material, allowing the injection barr...

Microfabricated silicon gratings as neutron-optical components

Microfabricated silicon gratings provide unique test procedures for instruments in neutron scattering and the interpretation of experimental data. Ultra-Small Angle Neutron Scattering (USANS) is currently becoming an effective technique for the analysis of structures in the micrometer range. A series of one-dimensional silicon gratings was fabricated using a highly anisotropic ion etching techn...

A microfabricated deformability-based flow cytometer with application to malaria.

Malaria resulting from Plasmodium falciparum infection is a major cause of human suffering and mortality. Red blood cell (RBC) deformability plays a major role in the pathogenesis of malaria. Here we introduce an automated microfabricated "deformability cytometer" that measures dynamic mechanical responses of 10(3) to 10(4) individual RBCs in a cell population. Fluorescence measurements of each...

Measuring the CO2 flux at the air/water interface in lakes using flow injection analysis.

The carbon dioxide flux at the air/water interface in lakes was calculated after the determination of H2CO3* (free CO2) and atmospheric CO2 using flow injection analysis (FIA) coupled to a conductometric detector. The method is based on the diffusion of CO2 through a hydrophobic membrane into a flow of deionized water, generating a gradient of conductivity proportional to the concentration of C...
