The Metrology of Counting Protein Particles

July 13, 2013
Author(s)
Dean C. Ripple, Michael J. Carrier, Richard E. Cavicchi, Christopher B. Montgomery, Zhishang Hu
A common degradation pathway for protein-based drugs is the growth of protein aggregates or particles. Counting and characterization of these particles is needed to assure the quality, efficacy, and safety of this type of drug. The unusual physical

Rapid-Heating of Ionic Energetic Materials using a Micro-Differential Scanning Device

July 10, 2011
Author(s)
Nicholas W. Piekiel, Richard E. Cavicchi, Michael R. Zachariah
We employ a microcalorimeter device to study the thermal decomposition of organic energetic materials at very high heating rates. The compact size of this device enables rapid heating rates and sensitive detection of thermal loads from very small samples

Calorimetric Sensors

April 15, 2011
Author(s)
Richard E. Cavicchi
The calorimetric gas sensor has evolved from a simple metal hot wire to a modern device fabricated using micromachining techniques. The principle of operation is to detect the heat evolved from combustible gases on the sensor surface. While the most widely

A Simple Method to Assess the Thermal Mechanisms Associated with a Fire Suppressant

April 1, 2010
Author(s)
Cary Presser, C Avedisian, J. Stiehl, Richard E. Cavicchi
A new screening concept is presented to evaluate the thermal effectiveness of fire suppressants (liquids and gases) for solid surface cooling (without vaporization for liquid suppressants) under well-controlled conditions. The concept is based on measuring

Enhanced Mass Transport in Ultra-Rapidly-Heated Ni/Si Thin-Film Multilayers

November 15, 2009
Author(s)
Lawrence P. Cook, Richard E. Cavicchi, Nabil Bassim, Susie Eustis, Winnie Wong-Ng, Igor Levin, Ursula R. Kattner, Carelyn E. Campbell, Christopher B. Montgomery, William F. Egelhoff Jr., Mark D. Vaudin
We have investigated multilayer and bilayer Ni/Si thin films by nano-differential scanning calorimetry (DSC) at ultra rapid scan rates, in a temperature-time regime not accessible with conventional apparatus. DSC experiments were completed at slower scan

High Temperature Electrical Resistance of substrate-supported Single Walled Carbon Nanotubes

January 1, 2008
Author(s)
Richard E. Cavicchi, C Avedisian, Paul M. McEuen, Xinjian Zhou, Wilbur S. Hurst, Joseph T. Hodges
We report the electrical characteristics of two substrate-supported metallic single walled carbon nanotubes (SWNT) at temperatures up to 573 K over a range of bias voltages for zero gate voltage in air under atmospheric pressure. At low voltages or high
