Tension prediction using web moving speed and natural vibration frequency

Du X., Yan J., University of Massachusetts Amherst, US

The characterization of web dynamics is critical for web handling and process control of roll-to-roll (R2R) manufacturing systems. One such critical characterization parameter is the tension in a moving web, which ultimately determines the efficacy [...]

Beyond Biomarkers: Array-Based Profiling for Diagnostics and High-Throughput Screening

Rotello V., University of Massachusetts Amherst, US

The "chemical nose/tongue" approach presents a potential alternative to specific recognition and separations techniques. In this approach a sensor array is generated to provide differential interaction with analytes via selective receptors, generating a stimulus response [...]

Self-Healing Wire-Streaming Processors on 2-D Semiconductor Nanowire Fabrics

Wang T., Bennaser M., Guo Y., Moritz C.A., University of Massachusetts Amherst, US

One of the most promising underlying nanodevice technologies today for nanoscale integrated circuits are semiconductor nanowires (NWs) and arrays of crossed NWs. Researchers have already built FETs and diodes out of NWs. There has also [...]

Elastic Network Model of Polymer Nanocomposites

Jang Y., Nair S., Kim M.K., University of Massachusetts Amherst, US

We present a novel simulation technique for modeling the nano and micro scale behaviors of plastic flow and fracture around crack tips of polymer nanocomposites. A coarse-grained elastic network model (ENM) simply represents the interations [...]
