Upcoming VBRS Meeting Schedule and Details

Thursday, November 15, 2018

Aromatic Carbons in Flames and Space - Hosted by Ferrum College

PROGRAM:

5:30 PM — Social Time

6:00 PM to 7:00 PM — Dinner

7:00 PM — Lecture

The speaker will be Dr. Houston Miller, Professor of Chemistry at George Washington University.

Summary: A bright yellow glow is a ubiquitous feature of most fires and flames and is known to anyone who has ever stared at a candle flame. This emission is from very hot, nanometer-sized particles of mostly carbon, along with smaller quantities of some other elements, especially hydrogen. Given the central role that these particles hold in the human experience, it is remarkable that the details of how they are formed are not fully known. Processes that occur in flames happen quickly. Small particles containing perhaps a million carbon atoms are assembled in less than one second from molecules that contain only a few carbon atoms. Thus, this chemistry involves thousands (perhaps millions) of successive steps and just as many intermediates. To compound the problem, laboratory diagnostics that are usually applied to the study of soot formation typically give us information about small molecules or relatively large particles, leaving a great deal of uncertainty about what happens in between. Prof. Miller will describe his experimental investigations of these important transformations.

The social time, dinner, and talk will take place in the Blue Ridge Mountain Room in Franklin Hall at Ferrum College.

The dinner is $15.00, with students and retired ACS members at half price. Reservations for the dinner must be made by Monday Nov 05, ten days before the meeting, by contacting Maria Puccio by e-mail at mpuccio@ferrum.edu or by phone at (540) 365-4238.
