MISSION

Increase our fundamental understanding of nucleation in all forms and explore practical applications of nucleation and nucleation - related processes through fundamental research.

 

VISION

An internationally recognized laboratory devoted to current, active nucleation research and available for interaction and collaboration with interested members of the nucleation community.

 

RESEARCH OBJECTIVES

  • Maintain an active, current research program devoted to all appropriate aspects of nucleation research.

  • Continue to make the Nucleation Laboratory available for research interactions in any mutually productive arrangement for both short and longer term collaborations.

  • Continue to promote the widespread dissemination of results of nucleation research especially as they relate to activities centered at the Nucleation Laboratory. 

 

 

 

 

HIGHLIGHTS OF RESEARCH ACTIVITIES

The High Pressure Diffusion Cloud Chamber

 

Schematic of the high pressure diffusion cloud chamber (HPCC) originally developed by and currently in use at the Nucleation Laboratory now located in the Chemical Engineering Department at Manhattan College.  The HPCC is the only currently available diffusion cloud chamber to allow investigation of vapor to liquid nucleation over wide ranges of nucleation temperature and total pressure.  Specific details concerning the design, construction, and operation of the HPCC are available in several of the publications listed on our Publication page.

Proper Ranges of Operation for Thermal Diffusion Cloud Chambers

 

Stability Diagram showing ranges of operation for the high pressure diffusion cloud chamber (HPCC) for 1-pentanol with hydrogen as the background gas.  Regions I and III are to be avoided as the data are expected to be unreliable.  This is an example of the first determination of acceptable ranges of operation of the thermal diffusion cloud chamber.  The wide range of temperature and pressure accessible to the HPCC made it possible to identify these ranges of improper operation for the first time.  Detailed discussions of diffusion cloud chamber stability are given in several of our recent publications.
