Days begin at: 11am ET/ 10am CT/ 9am MT/ 8am PT

All times below are expressed in Eastern. Please adjust accordingly.

Day 1: Monday, May 16

Day 1 Theme: A Nanoscience Approach to Understanding Environmental Samples

Click to view or download the workshop Day 1 recording (MP4 Video 584.6MB May21 22).
The goal of Day 1 is to introduce the audience to environmental nanoscience research using a case study that will be explored through a series of demonstrations (synchronous and asynchronous videos), discussions with live polls, and Q&A sessions. There will be an emphasis on sampling from environmental systems and the advantage of integrating data from multiple characterization methods.

Day 3: Wednesday, May 18

Day 3: Office Hours with Experts Session (Optional)

Participants will be able to sign up for 10 minute sessions with experts in topics of interest (via a pre-registration form - to be posted). The scheduling of the sessions will be determined based on the level of interest and schedules of leaders and participants. Participants will be able to talk directly about their research interests, and to solicit advice and feedback.
