This month’s Career Corner (p. 22) offers suggestions for coping with stress at work. For many of us, a major source of stress is the feeling that we have too much to do and not enough time to do it. There’s a counterintuitive solution to this...

Americans are spending more time working and less time sleeping, according to the U.S. Dept. of Labor’s American Time Use Survey. With longer hours spent at our jobs, many of us are experiencing more workplace stress. We face seemingly endless...

To design and analyze absorber columns, engineers need reliable mass-transfer parameters for rate-based models in process simulations. However, unlike for distillation, no set of standardized measurement methods for absorption have been generally accepted. Mass-transfer parameters measured by different methods at different facilities, or calculated from different correlations, can have significant disparities. Thus, a need exists to improve the precision and accuracy of experimental methods for determining mass-transfer coefficients so that reliable and coherent sets of data can be derived.
