Challenges in Characterizing Small Particles Workshop

A Chemical Sciences Roundtable Workshop

CHALLENGES IN CHARACTERIZING SMALL PARTICLES
Exploring Particles from the Nano- to Microscales

Date: October 25-26, 2010

This one and a half day workshop will explore new opportunities, challenges, and approaches to characterizing small particles and understanding their impacts. Small particles—about one nanometer to tens of microns—are ubiquitous in the natural and man-made worlds. In many scientific and engineering domains, uncertainty about the properties and chemical composition of small particles limits our ability to understand, predict, and control their applications and impacts.

There will be several overview presentations highlighting the critical importance of small particles in environmental science, materials and chemical sciences, biological science and in engineering. In addition, there will be several “research tool” presentations highlighting new advances in characterizing small particles. Characterization will include static, dynamic, experimental, computational and theoretical characterization.
