  8. 8. Letters Spontaneous combustion I enjoyed your advisory piece for chemical engineers — old and young: “Don’t wait to react” (CE, October, p. 5). Two weeks ago I gave a presentation on spontaneous combustion at a meeting of mulch facility operators. Of over 100 conference attendees, only one raised his hand when I asked how many operators had never had a problem with spontaneous combustion! I really enjoy the Chementator section of Chemical Engineering. Richard Buggeln, PhD Manager, Environmental Programs, Center for Industrial Services, University of Tennessee Help us support ChE education Striving to continually advance the chemical engineer- ing profession has been a goal for this magazine since its founding more than 107 years ago. To help cultivate new talent, CE established the annual Chopey Scholarship for Chemical Engineering Excellence in memory of Nicholas (Nick) P. Chopey, our former Editor In Chief. Nick carried many torches at CE including those for the Kirkpatrick and Personal Achievement Award competitions that are held in alternating years. To honor and continue Nick’s valuable and lasting con- tributions to the chemical engineering profession, CE will match up to $10,000 of all donations for the 2009 scholar- ship fund that are received prior to June 1, 2010. Donations. Checks should be made out to Scholarship America with “Nicholas P. Chopey Scholarship Program” in the memo area.

The schol- arship is a one-time award for current third-year students who are enrolled in a fulltime undergraduate course of study in chemical engineering at one of the following four- year colleges or universities, which include Mr. Chopey’s alma mater and those of the current editorial staff: University of Virginia University of Kansas SUNY Buffalo Columbia University Polytechnic University The program will utilize standard Scholarship America recipient-selection procedures including the consider- ation of past academic performance and future potential, leadership and participation in school and community activities, work experience, and statement of career and educational aspirations and goals. Applications must be postmarked by April 1. Guidelines are distributed directly to the chemical engineering department of the qualified schools.
