CEP: Process Automation Corner - Back to the Future on Energy

June
2014
Process Automation Corner
Terry McMahon
Energy is a very important factor in process automation. Improvements in energy efficiency gained through process automation played a key role in justifying the pioneering automation projects of the early 1960s and have grown in stature over the ensuing decades. Automation-enabled improvements in energy usage have made critical contributions to worldwide prosperity over the last 35–40 years.

CEP: Profile - Manu Prakash: Encouraging Curiosity-Driven Science

June
2014
Profile
One of the biggest hurdles to treating disease in developing countries is the lack of portable and cheap diagnostic instruments, such as microscopes. Manu Prakash, an assistant professor in the Dept. of Bioengineering at Stanford Univ., believes that frugal science is the key to enhancing global health and science education. Prakash is creating simple, economical tools to pique interest in science exploration and even perform field-testing for specific diseases, such as malaria. One such invention, the Foldscope, is a completely functional microscope that merges the principles of origami and optical design.

CEP: Catalyzing Commercialization - Ionic Liquids Charge Ahead as Battery Electrolytes

June
2014
Catalyzing Commercialization
Advances in energy-storage devices are a must for the widespread use of electric and hybrid vehicles, the integration of renewable energy with the electric power grid, and the development of smaller, faster, more-powerful consumer electronics. While progress has been made, several challenges remain, including limitations of nonaqueous electrolytes, which have poor transport properties and are highly flammable. The answer to this challenge: A new class of higher-performance electr-olytes being developed by Boulder Ionics Corp. (BI) for longer-lived, safer batteries and ultracapacitors.

CEP: AICHE Journal Highlight - A Broader Role for the Evolving Engineer

June
2014
Journal Highlight
Chemical engineers are primarily known for their tech-nical expertise. While this engineering know-how has played a key role in developing technologies essential for modern society, it will not be enough to solve the increasingly complex challenges of today’s world. Solutions to these issues, including the development of safe and sustainable food and water supplies, economical alternative energies, and more-effective pharmaceuticals, will require a multidisciplinary approach that considers political, social, and economic constraints, as well as the obvious technical challenges.

CEP: Commentary - Educating Students to Become Engineers

June
2014
Commentary
R Russell Rhinehart
The article “How Well Are We Preparing ChE Students for Industry?” in the Update section of the April issue of CEP (pp. 4–5, 14–15) meshed with my career-long concern about engineering education. I graduated in 1968, with pride in my skills, from “a strong program” that “was about to break into the top ten,” as we were told. It was a good program in many ways, but after two years in industry, I came to realize the misdirected perspectives I had acquired as a student. After 13 years in industry and 28 in academia, I have concluded that neither the academic perception of excellence nor the tasks students are required to complete align with the perceptions and tasks that lead to success in industry.

CEP: Career Corner - Is Starting a Consulting Practice Right for You?

June
2014
Career Corner
Loraine Kasprzak
Are you considering starting your own engineering consulting practice? One of my best career moves was leaving my corporate position to open my own consulting firm. Perhaps, like me, you were bitten by the entrepreneurial bug, or perhaps your current employer is downsizing and a severance package will provide you with the opportunity you have been waiting for — not to mention the cash reserves you need to get through your first year. Consulting may seem like a glamorous career, one in which you get to work when you want and make lots of money. Nothing could be further from the truth. You must be able to work without having the structure and accountability that being employed by someone else provides.

CEP: Editorial - Getting ChE Education Right — Part 2

June
2014
Editorial
Cynthia Mascone
Our discussion of chemical engineering education began in the April issue, with the news story “How Well Are We Preparing ChE Students for Industry?” and my editorial, “Getting ChE Education Right.” This month, we look at education again, with two more articles. The April articles resonated with Russ Rhinehart, a professor at Oklahoma State Univ., and inspired him to write a letter to the editor, which became this issue’s Commentary, “Educating Students to Become Engineers” (pp. 14–15). By coincidence, the AIChE Journal Highlight, “A Broader Role for the Evolving Engineer” (p. 13), also focuses on education.

Any safety device can create a new hazard. Any change to equipment, even one intended to improve safety, can create new hazards or make other existing hazards more severe. This is particularly true if the safety device is not properly installed.

CEP: Spotlight on Safety - Normalization of Deviation — Identify It, Correct It, Prevent It

Spotlight on Safety
Louisa Nara
Whether we are talking about occupational safety or process safety, normalizing a deviation can result in unsafe practices, conditions, and operations. Getting comfortable with and accepting these deviations can cause a shift in our perception of what is safe. Why does this matter? Moving the target for safe operating limits and tolerating the higher risk s associated with doing so can ultimately lead to a catastrophic incident.

CEP: YPOV - Preparing for Chairing? Build Some Relationships!

March
2014
YPOV
Meagan Lewis
Programming for an AIChE conference — i.e., developing the technical program — takes a lot more than the work put in by the meeting chairs; the details and ideas that go into every session and its roster of speakers take a whole force of volunteers. As a co-chair for the upcoming 2014 Spring Meeting in New Orleans who also happens to be a young professional (YP), I’ve realized that the best way to prepare for programming a large-scale conference is to build relationships across all levels of the organization.

CEP: Catalyzing Commercialization - Food-Safety Testing Gets a Much-Needed Makeover

May
2014
Catalyzing Commercialization
More than 75% of the world's food testing continues to rely on 120-yr-old cell-culture methods, which take days to produce results. New technology developed by scientists at Rheonix Inc., based in Ithaca, NY, is enabling a portable unit that greatly simplifies the testing through automation, providing results in hours instead of days and reducing costs. Thermo Fisher Scientific Inc. has incorporated the Rheonix technology into a new generation of PCRbased rapid analysis for the food- and beverage-testing markets.

CEP: AIChE Journal Highlight - Unraveling the Drying Droplet Problem

May
2014
Journal Highlight
The familiar ring-shaped stain left behind after spilled coffee has dried represents a complex engineering problem involving principles of heat and mass transport, fluid mechanics, and surface phenomena (among others) whose solution has value well beyond spilled coffee, including the analysis of DNA microarrays, inkjet printing, and coating. In the May AIChE Journal review article, “Transport and Deposition Patterns in Drying Sessile Droplets,” Ronald Larson of the Univ. of Michigan examines this engineering problem — understanding the processes by which a liquid drop (containing nonvolatile solute or colloidal particles) on a surface evaporates and leaves behind the particles that form a stain.
