Prof. Topper Gives Talk at Queensborough Community College

POSTED ON: September 17, 2014

The reaction between ammonia and hydrogen chloride to form solid NH4Cl has been studied for many years, serving as a prototype system for an improved understanding of acid-base chemistry. Recently, studies have found that aerosols containing NH4Cl particles form atmospherically in polluted marine and coastal environments. This motivated us to try to predict the relative stabilities of differently-sized NH4Cl nanoparticles in the gas phase. In this lecture we will discuss our methods and findings, as well as our current work on other ammonium halides.

  • Founded by inventor, industrialist and philanthropist Peter Cooper in 1859, The Cooper Union for the Advancement of Science and Art offers education in art, architecture and engineering, as well as courses in the humanities and social sciences.

  • “My feelings, my desires, my hopes, embrace humanity throughout the world,” Peter Cooper proclaimed in a speech in 1853. He looked forward to a time when, “knowledge shall cover the earth as waters cover the great deep.”

  • From its beginnings, Cooper Union was a unique institution, dedicated to founder Peter Cooper's proposition that education is the key not only to personal prosperity but to civic virtue and harmony.

  • Peter Cooper wanted his graduates to acquire the technical mastery and entrepreneurial skills, enrich their intellects and spark their creativity, and develop a sense of social justice that would translate into action.
