AIChE Journal Highlight - Tribute to Founders: Neal R. Amundson

September
2013
Journal Highlight
Chemical engineering as it is known today — in which theoretical models are used to design and maintain processes — bears only a slight resemblance to the nascent field. In its beginnings, chemical engineering involved the dissection of chemical processes into unit processes and unit operations using mostly empirical methods. Material and energy balances soon entered the scene in the late 1920s, followed by the introduction of transport phenomena. While many scientists and engineers contributed to the evolution of chemical engineering, one man in particular stands out. Neal Russell Amundson, who became a full professor of chemical engineering at the Univ. of Minnesota at the age of 35, can be credited for the proliferation of scientific content within the chemical engineering field and profession.

CEP: AIChE Journal Highlight - Needed: ChEs to Solve Global Challenges

August
2013
Journal Highlight
Chemical engineers and sound engineering principles have been absent from the discussions of global challenges — energy, climate change, food, and water — for too long, assert Bill Banholzer and Mark Jones of Dow Chemical in their August AIChE Journal Perspective article, “Chemical Engineers Must Focus on Practical Solutions.” Society has thus confused what is possible with what is practical, particularly when it comes to energy, where new discoveries are greeted with over-excitement and the hope that each will provide the means to supply reliable, cheap, and almost-limitless energy, the authors say. They cite the hydrogen economy, cellulosic ethanol, and fuel cells as examples of technologies that have promised much but delivered little

CEP: Editorial - Are Leaders Born or Made?

August
2013
Editorial
Cynthia Mascone
Countless books and articles have been written about leadership — on such topics as the differences between managing and leading, what makes a good leader, and how to become a better leader, among others. One frequent topic: Are leaders born or made? The Center for Creative Leadership (CCL) posed this question to C-level executives of companies in 53 countries ( www.ccl.org/leadership/pdf/research/areleadersbornormade.pdf ). Slightly more than half (53.4%) of the top executives think leaders are made, about a fifth (19.1%) think they are born, and a little more than a quarter (28.5%) think leaders are both born and made.
