We have developed a simple, low-cost electronic interface suitable for use with piezoresistive microcantilever-based sensors. This interface uses the USB bus of any computer or laptop to communicate with the sensor via SPI commands. The primary user interface is LabView. We have used this system with several “embedded” piezoresistive microcantilever sensing applications, including both liquid-p...

We describe several transinterface electron-transfer processes occurring at the benzonitrile (PhCN)/water interface that produce excited states. When an electrode was moved very close to the interface or even through the interface to produce an electrode/thin layer organic phase/aqueous solution configuration, the electrogenerated radical species formed in the PhCN phase (C12-Ru(bpy)3, DPA+, or...

We study a tumor growth model in two space dimensions, where proliferation of the cells leads to expansion domain and migration surrounding normal tissues into exterior vacuum. The features moving interfaces separating tumor, tissue, prove local-in-time existence uniqueness strong solutions for their evolution starting from nearly radial initial configuration. It is assumed that has lower mobil...
