Combining Microfluidics and Microrheology to Determine Rheological Properties of Soft Matter during Repeated Phase Transitions Matthew D. Wehrman1, Melissa J. Milstrey1, Seth Lindberg2, Kelly M. Schultz1 1Department of Chemical and Biomolecular Engineering, Lehigh University, 2Process and Engineering Development, Procter & Gamble Co. We demonstrate the fabrication and use of a microfluidic device that enables multiple particle tracking microrheology measurements to study the rheological effects of repeated phase transitions on soft matter.
Preparation and Use of Samarium Diiodide (SmI2) in Organic Synthesis: The Mechanistic Role of HMPA and Ni(II) Salts in the Samarium Barbier Reaction Dhandapani V. Sadasivam1, Kimberly A. Choquette1, Robert A. Flowers II1 1Department of Chemistry, Lehigh University A straightforward procedure for the preparation of samarium diiodide (SmI2) in THF is described. The role of two main additives namely hexamethylphosphoramide (HMPA) and Ni(acac)2 in Sm mediated reactions is demonstrated in the Sm-Barbier reaction.
