CNM Characterization Workshop – Primary Characterization



Johan Foster, UBC

Robert Moon, USFS


When:  Monday, June 14, 1:00-3:30pm


Workshop Overview:

For the advancement in understanding, process optimization, and utilization of cellulose nanomaterials (CNMs) it is critical to use characterization measurement protocols that give consistent, reliable and accurate results.  However, because of the exponential growth in interest/activity in CNMs, much of the development of these measurement protocols have been outpaced.  This 2½ hour workshop helps to address this gap by providing summaries/outlines details the best practices and limitations for several techniques/methods typically used for the characterization of CNMs, in particular, surface charge, surface characterization, crystallinity determination and mechanical properties.  Each topic will be covered by experts in the field for the given technique, with the purpose to inform the audience why one should consider using a given technique (e.g., use “this” technique for “that” reason”), then provide a detailed best practice for the technique (e.g., “here is the proper way to do “this” technique). Where possible examples have been given to highlight how “this” technique shows “these” data on “these” CNMs.   Throughout the workshop, specific comments are made regarding any differentiation in the characterization of CNC versus CNF. 


Workshop Topics:


Who should attend?

Anyone in industry or academia who is a beginner/novice in conducting standard materials characterization of CNMs.  The presentation style and content for this year’s workshop is similar to that given at Nano2018 and Nano2019, however, there are notable updates in charge titration, and new topic on surface characterization.

EHS: Commercializing Cellulose Nanomaterials - Nordic and International Requirements for Safe Manufacturing and Product Development


Workshop Faculty:

Jo Anne Shatkin, Ph.D., President, Vireo Advisors, LLC

Julia Catalan, Ph.D., Senior Researcher, Finnish Institute of Occupational Health

Gary Chinga-Carrasco, Ph D, Senior Researcher, RISE PFI, Norway

Kimberly Ong, Ph.D., Nanotoxicologist, Vireo Advisors, LLC

James Ede, Ph.D., Nanotoxicologist, Vireo Advisors, LLC


Workshop Overview:

The workshop will focus on market-specific requirements for safety demonstrations for new substances, with focus on cellulose nanomaterial applications. A panel of governmental scientists will discuss international approaches on occupational safety for nanomaterials. Concepts will be explored with case studies to present current knowledge, theory, and practices for meeting market-specific regulatory requirements. The workshop will be presented by Vireo Advisors, an international advising firm from North America, in collaboration with Julia Catalan of the Finnish Institute for Occupational Health.
