Catalyzing Commercialization
Improvised explosive devices (IEDs) are not just a threat to military troops but to civilians as well. Thwarting these attacks will require many measures, one of which is improved screening technologies. Vaporsens, a Univ. of Utah spin-off company, is developing a sensor that could meet the need for a portable, inexpensive explosives-screening device.

CEP: Editorial - Navigating Ethical Dilemmas

February
2015
Editorial
Cynthia Mascone
It seems not a day passes without news reports of a politician or corporate executive taking bribes, engaging in insider trading, or getting caught up in some other ethical dilemma. As engineers, though, we will more likely find ourselves in situations that have subtler, less-obvious ethical undertones.

CEP: YPOV - Engineering Your Job Change through Networking

January
2015
YPOV
Sarah Ewing
In the current job market, people rarely stay employed with the same company that hired them after college for their entire career. If you want to take control of your career and make a job change that is consistent with your professional and personal goals, allow enough time to weigh the pros and cons instead of making the decision on a whim. The most critical step in this process is not updating your resumé, but making sure that the new position will be a good fit and not just a quick fix. I like to think of changing jobs as a process with four key steps: recognizing that it is time to move on, deciding where you want to go, determining what you need to get there, and then networking your way in.

CEP: Process Safety Beacon - What Is the Process Risk?

January
2015
Process Safety Beacon
The worst process incident that can happen in your plant may not be the same as the highest process risk. Risk is a combination of how likely an incident is and how bad the consequences could be. The process incident in your plant with the worst consequences may be very unlikely to occur. Other less-severe incidents may be more likely, making the risk of these events higher than the incident with the worst consequences. You should be aware of all process risks in your plant, and your role in managing all of them.

CEP: AIChE Journal Highlight - Solving Wicked Sustainability Problems Requires a New Approach

December
2014
Journal Highlight
The challenges facing the world today — including climate change, resource scarcity, food security, water access, and energy demand — are fundamentally different than those of the past. These sustainability issues can be thought of as “wicked” problems — a concept that originated in the 1970s to describe the difficult challenges facing urban planners at the time and that has now spread to other areas, including engineering. In contrast with so-called tame problems, which can be solved by traditional linear, analytical approaches, wicked problems are much more intractable and very difficult to solve.

Yes, I can access books and newspapers on my iPad. But actually reading them is another matter.

CEP: AIChE Journal Highlight - ChE Education: How Times Are Changing

November
2014
Journal Highlight
The chemical engineering curriculum has changed over the years and will continue to change in the future. In the November AIChE Journal Perspective article, “Evolving Trends in Chemical Engineering Education,” Arvind Varma of Purdue Univ. and Ignacio Grossmann of Carnegie Mellon Univ. examine this evolution and illuminate the impacts of shifts in academic research and industry needs. Taking a close look at the history and likely course of chemical engineering education provides a basis for discussing whether this trajectory is heading in the right direction to meet the needs of industry and to address societal issues.
