I am delighted to share some highlights from the past few months. In November I traveled around the world with four Macro students for a scientific and cultural exchange at the Nara Institute of Science & Technology (NAIST). Two NAIST faculty and six students had visited for the Macro symposium in October and we were excited to have the opportunity to visit their institution. Modern day science and engineering challenges are global in nature and impact, and we are delighted to be continuing these important efforts initiated by former Director Rick Laine.

Professor Craig Hawker, Director of the Materials Research Laboratory, Honored with 2013 ACS Award in Polymer Chemistry
September 11, 2012 Professor Craig Hawker, Director of the Materials Research Laboratory, Honored with 2013 ACS Award in Polymer Chemistry Craig Hawker, professor of materials, is one of two UC Santa Barbara professors who have been named recipients of the American Chemical Society's 2013 national awards for professional advancement. Professor Hawker, who is also the Director of the Materials Research Laboratory, has been named recipient of the ACS Award in Polymer Chemistry. The award citation states that Hawker was nominated for transforming the field of polymer chemistry through the clever adaptation of synthetic organic chemistry concepts and the advancement of macromolecular engineering. ExxonMobil Chemical Company sponsored this award. "I am thrilled with the award and the recognition that it brings to my students, collaborators, and co-workers, as well as to the unique research environment at UCSB," said Hawker. "The sustained success of cross-disciplinary research has been a key driver in reinforcing UCSB's international standing in the materials chemistry arena. I am grateful for the enormous benefits that this proud tradition has bought to my research." Hawker is among 64 award winners from across the nation. In only one other year, 1996, did UCSB claim more than one winner of the American Chemical Society (ACS) awards. The awards will be presented at the national ACS meeting in New Orleans in April. Hawker received his Ph.D. from the University of Cambridge, and then completed a postdoctoral fellowship with Jean M. J. Fréchet at Cornell. In 2004, he joined the faculty at UCSB from the IBM Almaden Research Center. -

WEEKS, Emory University — We study concentrated colloidal suspensions, a model system which has a glass transition. These are suspensions of small solid particles in a liquid, and exhibit glassy behavior when the particle concentration is high; the particles are roughly analogous to individual molecules in a traditional glass. We view the motion of these colloidal particles in three dimensions by using an optical confocal microscope. This allows us to directly study the microscopic behavior responsible for the macroscopic viscosity divergence of glasses. In particular, we study how confinement changes the particle dynamics. We confine a colloidal suspension between two parallel walls, and find that in thin sample chambers the particle motion is greatly slowed. This suggests that confinement causes the onset of the glass transition to happen “sooner,” at particle concentrations which are not normally glassy. 1Supported by the National Science Foundation under Grant No. DMR-0239109. 8:36AM A29.00002 Periodic Stresses and Shear Thickening in an Attractive Colloidal Gel1 , CHINEDUM OSUJI, DAVID WEITZ, Applied Physics, Harvard University — We report on the observation of periodic stresses in a colloidal gel at rest and under minute shear deformation. Dilute suspensions of carbon black colloidal particles in hydrocarbon oil with an attractive Van der Waals interaction are found to shear thicken in two distinct regimes. The first, low shear rate regime is ascribed to network elongation and the high shear regime to hydrodynamic clustering, akin to that observed in concentrated hard sphere systems. -
