“A Universal Data Analytics Platform for Science” by Argonne Scholar Ryan Chard (DSL)
Abstract
This talk presents our progress toward developing A Universal Data Analytics Platform for Science (AUDAPS). AUDAPS makes scientific data, regardless of location, readily available and accessible, enabling self-optimized analysis with cutting-edge tools across a broad set of computing platforms. AUDAPS addresses the problem of securely and reliably automating, for many thousands of scientists, sequences of data management tasks that may span locations, storage systems, administrative domains and timescales, and integrate both machine and human inputs. Here I will present our vision, describe preliminary work in several key areas as well as initial applications to neuroscience, genomics and materials science, and finally outline our future plans.

“Production of Cellulose Nanocrystals from Miscanthus x. Giganteus” by Consultant Engineer Erik Dahl (AMD)
Abstract
Cellulose is the most abundant organic compound on earth and occurs naturally as a hierarchical architecture of fiber bundles that contain both highly crystalline and amorphous domains. Removal of the amorphous region allows access to highly crystalline, rod-like cellulose nanocrystals (CNC) and the hydrolysis of natural cellulose to yield CNCs is well known. A number of commercial producers in the US, Canada, Japan and Sweden have started to appear. In each case their feedstock is wood.
Our research has focused on the development of a large-scale process for the production of cellulose nanocrystals derived from the energy crop Miscanthus x. Giganteus (MxG). MxG is a perennial, non-invasive hybrid. In our current research we have worked to develop efficient and environmentally sustainable processes to produce CNC from MxG. An overview of the process research and development project and recent statistical modeling will be discussed.
Biography
Erik Dahl earned his B.Sc. in chemical engineering from the Illinois Institute of Technology. His research work has included variable biomass feedstock gasification, gas to liquids processes and zinc-air batteries. As an engineer working in the specialty chemical industry, his work focused on process development, scale up and design. His current work is the development and optimization of cellulose nanomaterial processes.
