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 - Zero-Emissions Magnesium Process Debuts

March
2014
Catalyzing Commercialization
A process designed to lower the cost of magnesium metal, making it competitive with aluminum, has been an industry goal for over a century. Although magnesium metal makes up millions of today’s lightweight cell phone and laptop cases, its persistently high cost (twice that of aluminum today) has impeded broad, high-volume use in other areas, including the automobile industry. This could soon change, thanks to researchers at INFINIUM, based in Natick, MA, who have developed a low-cost, energy-efficient, zero-emissions process for making this lightweight, strong metal.

Cynthia Mascone
You’ve spent hours writing your paper, preparing the slides for your presentation, and practicing your talk. You’ve endured the humiliation of the airport security inspection, the frustration of the weather-related flight delay, the discomfort of the cramped airplane seats, and the disruption of your circadian rhythm after crossing several time zones. You arrive at the meeting room early, check your slides on the session chair’s laptop, get comfortable with the remote, and test the mic. You are excited to be part of this group of experts, and are looking forward to sharing your thoughts and engaging in a lively dialogue.

CEP: Process Automation Corner - The U.S. Process Automation Enterprise Looks to the Future

March
2014
Process Automation Corner
Terry McMahon
The outlook is bright for the process automation enterprise in the U.S. through this decade and into the next. Process automation skills and know-how are honed through challenging projects and are perfected by maintaining these systems at peak efficiency. Without constant renewal based on new and different challenges, these skills tend to atrophy and become obsolete. Fortunately, after more than a decade of decline, the U.S. process industries are entering a period of highly advantaged resource and energy availability.

CEP: Editorial - More Than a Spoonful of Sugar

March

Editorial
Cynthia Mascone
Many of us remember receiving our polio vaccine on a sugar cube. Indeed, that was the motivation behind A Spoonful of Sugar, a song from the classic Disney movie Mary Poppins. Walt Disney had instructed the Sherman brothers, Robert and Richard, to come up with a catchy song for the film. When Robert arrived at home, after working all day trying to come up with an idea, his wife told him that the children had gotten their polio vaccine that day. Thinking they had gotten a shot, he asked them if it hurt. His son answered that the medicine was put on a cube of sugar and he swallowed it. And so “a spoonful of sugar helps the medicine go down was born.
