DESCRIPTION:Abstract:\n\nBiomineralization\, the study of how organisms for
 m minerals such as bones\, teeth\, and shells\, provides examples of strat
 egies for controlling the growth of crystalline materials patterned at the
  nanoscale. In particular\, the use of nanostructured organic and inorgani
 c interfaces to guide assembly and crystallization pathways can result in 
 materials with precisely-controlled structures across length scales. The w
 ork focuses on three materials platforms to elucidate solution-based assem
 bly pathways\, with an increasing focus on.\n\nIn this presentation\, I wi
 ll focus on several related efforts that focus on understanding the role o
 f the solid-liquid interfaces in directing the interaction between polymer
 ic materials and inorganic crystals. First\, I will discuss our recent flu
 id cell Atomic Force Microscopy (AFM) studies of calcite growth in the pre
 sence of polymeric and inorganic nanoparticles with varying surface chemis
 tries. In this study\, we are investigating the role of the solid-liquid i
 nterface in directing the incorporation of secondary (nanoparticle) phases
  during crystallization. Second\, I will present our work using nanopatter
 ned block copolymer templates to control the nucleation and gorwht of inor
 ganic materials. For both of these strategies\, I will present results rel
 ated to the formation mechanisms and internal structures of the resulting 
 nanostructured crystals. Together\, these studies have the potential to le
 ad to design criteria for composite single-crystals with unique structure-
 property relationships. In addition\, insights provided by this work may h
 elp to elucidate the formation mechanism(s) and properties of biogenic sin
 gle crystals with incorporated organic material.\n\n \n\n \n\nBio:\n\nLara
  A. Estroff received her B.A. with honors from Swarthmore College (1997)\,
  with a major in Chemistry and a minor in Anthropology. Before beginning h
 er graduate studies\, she spent a year at the Weizmann Institute of Scienc
 e in Rehovot\, Israel as a visiting researcher in the labs of Profs Lia Ad
 dadi and Steve Weiner. During this time\, she was introduced to the field 
 of biomineralization and studied chemical approaches to archeological prob
 lems. In 2003\, she received her Ph.D. in Chemistry from Yale University f
 or work done in Prof. Andrew D. Hamilton's laboratory on the design and sy
 nthesis of bio-inspired organic superstructures to control the growth of i
 norganic crystals. After completing graduate school\, she was an NIH-funde
 d postdoctoral fellow in Prof. George M. Whiteside's laboratory at Harvard
  University (2003-2005). Since 2005\, Dr. Estroff has been in Materials Sc
 ience and Engineering department at Cornell University and in 2023 she was
  named the Herbert Fisk Johnson Professor of Industrial Chemistry. She ser
 ved as the Director of Graduate Studies in the department from 2015-2019. 
 As of August 2020\, she is the current Chair of the Materials Science and 
 Engineering department. Her group focuses on bio-inspired materials synthe
 sis\, crystal growth mechanisms\, and the high-resolution characterization
  of pathological mineralization. She has received several awards\, includi
 ng an NSF Early Faculty Career Award in 2009 and a J.D. Watson Young Inves
 tigator’s award from NYSTAR in 2006.\n
