Recommended viscosities of 11 dilute gases at 25?degC

December 13, 2012
Author(s)
Robert F. Berg, Michael R. Moldover
Commercially manufactured meters that measure the flow of a process gas are often calibrated with a known flow of a surrogate gas. This requires an accurate model of the flow meter and accurate values of the relevant thermophysical properties for both

SCIENCE-BASED METRICS FOR PRODUCT SUSTAINABILITY ASSESSMENT

September 30, 2012
Author(s)
Barbara C. Lippiatt
Consumers and manufacturers need compelling metrics, tools, and data supporting investments in sustainable products. Today’s marketplace is fraught with sustainability claims that are often based on incomplete, anecdotal evidence that is difficult to

A Combinatorial Study of Thin Film Process Variables Using Microhotplates
