CEP: Process Safety Beacon - Safe Work Practices

April
2015
Process Safety Beacon
The term safe work practices refers to the processes we use to authorize nonroutine work activities, and to control the hazards and manage the risks associated with these activities. Safe work practices often authorize work through permits, which frequently include checklists of potential hazards associated with the work. A nonroutine activity has nothing to do with how often the activity is done. Instead, it refers to activities that are not part of the normal process for converting raw materials to finished product, and not covered by the plant’s standard operating procedures for normal operations.

CEP: Catalyzing Commercialization - Nanocrystal Manufacturing May Revolutionize Thermoelectrics

April
2015
Catalyzing Commercialization
Thermoelectric materials hold promise as a means to recover waste heat from automobile exhaust, power plants, and other systems. Their use, however, is limited by low efficiency. Researchers at Rensselaer Polytechnic Institute have developed a process that combines nanostructuring, compositional control, and ppm-level impurity doping. ThermoAura, Inc., a start-up company co-founded by the researchers, has scaled up this process to manufacture high-performance thermoelectrics with tunable properties.

CEP: Material Matters - Tool Helps Predict Reactivity Hazards

April
2015
Material Matters
Kirk Richardson
To provide guidance and disseminate reactivity data, the National Oceanographic and Atmospheric Administration (NOAA), in conjunction with partnering companies and technical associations, developed the Chemical Reactivity Worksheet (CRW). The free software ( http://response.restoration.noaa.gov/reactivityworksheet ) allows CPI professionals to review the reactivity hazards of thousands of individual chemicals, as well as predict the consequence of mixing chemical substances. Since its release in March 2013, the CRW Version 3 (CRW3) has been downloaded approximately 80,000 times.

CEP: AIChE Journal Highlight - Layer-by-Layer Approach Enables Customizable Medication Therapy

April
2015
Journal Highlight
In the April AIChE Journal Perspective article, “Layer-by-Layer Approaches to Staging Medicine from Surfaces,” Paula T. Hammond of the Massachusetts Institute of Technology describes her research on a method that creates layers of thin films stacked on top of one another. Each layer contains a different therapeutic, which is incorporated into the thin film via one of several mechanisms (e.g., charge, hydrogen bonding, or other complementary interaction). This technique is useful for drug therapy in applications such as bone regeneration.

CEP: Editorial - Stand Up for Change

April
2015
Editorial
Cynthia Mascone
In the article “Recognize Hazards to Recognize Change” (pp. 40–44), Donald Lorenzo, Della Wong, and Mark Suyama liken managing change in the chemical process industries (CPI) to the challenge of piloting a ship on a voyage. Subtle changes in winds, waves, currents, and tides are difficult to discern, but each small change becomes the new normal, and the next change seems to be only a small difference. Only after the ship hits an obstruction does the captain realize how severely the ship has veered off course. That was the inspiration for this issue’s cover.

CEP: Career Corner - How to Communicate Difficult Messages

Career Corner
Loraine Kasprzak
Have you had to deliver a difficult message to someone lately? Perhaps it was to an individual whose performance was below expectations. Or maybe it was to a group of employees about upcoming layoffs or cancelled bonuses. It wasn’t fun, was it? As a past corporate manager and now as a business owner, I have been on both sides of these difficult conversations and know it can be just as stressful to deliver bad news as it is to receive it.

Best known for his defining book on transport phenomena — in which he provided chemical engineering students with an integrated view of the transport of the three physical quantities (energy, mass, and momentum) at three different scales (molecular, microscopic, and macroscopic) — R. Byron Bird has immensely impacted the field of chemical engineering.

CEP: Editorial - Getting ChE Education Right

April
2014
Editorial
Cynthia Mascone
When I was in college, I earned some spending money as a shoe model for a local freelance photographer. Little did I know I would become a cover girl. But a few years later, shortly after I began my career as an editor (at a different magazine), I was tapped for just that role. Wearing a black cap and gown and photographed looking out into a maze of piping in a chemical plant, I represented a young graduate facing my first job in industry. The cover line — “Chemical engineering education: How good is it, really?” — referred to an article that discussed the results of a reader survey conducted by two of my colleagues. That was 31 years ago. Today, we are still pondering the same question.
