Sandra J. Rosenthal (born 1966) is the Jack and Pamela Egan Professor of Chemistry, professor of physics and astronomy, pharmacology, chemical and biomolecular engineering, and materials science at Vanderbilt University. She is a joint faculty member at Oak Ridge National Laboratory in the Materials Science and Technology Division and the director of the Vanderbilt Institute of Nanoscale Science and Engineering.

Contents

Rosenthal is an acclaimed researcher in the field of nanoscience and nanomaterials. She has received national awards for her research endeavors and has also been actively engaged in STEM outreach programs which have benefitted students throughout the Middle Tennessee Region. Rosenthal's independent scientific career has been distinguished by her innovative studies on nanomaterials, most notably quantum dots and nanoclusters. She is the leader of a highly interdisciplinary research team [1] based at Vanderbilt University which is focused on endeavors that span the fundamental study of quantum dots at the atomic scale to the development of designer nanomaterials for applications in diverse research areas spanning solid-state lighting to biological imaging. A major focus of Rosenthal's current research is "to develop and use nanotechnology to elucidate molecular mechanisms of mental illness". [2]

Education, career, and service

Rosenthal received her B.S. with Honors in the field of Chemistry from Valparaiso University (1987). [3] Rosenthal played 4 years of Division 1 basketball for Valparaiso University while receiving her undergraduate degree. [4] [5]

She went on to receive her Ph.D. in chemistry from the University of Chicago with Graham Fleming where her thesis was on "Femtosecond solvent dynamics: observation of the inertial contribution to the solvent response" (1993). [6] From 1993–1995, Rosenthal was a National Science Foundation Postdoctoral Fellow at Lawrence Berkeley National Lab and UC Berkeley where she worked with Paul Alivisatos and Charles Shank. During her time as a postdoctoral fellow, Rosenthal began her involvement with spectroscopic studies [7] on quantum dots. In 1996, Rosenthal began her independent faculty position on the Chemistry faculty at Vanderbilt University. Her independent research career has continued to be distinguished by her studies on quantum dots and nanomaterials.

At Vanderbilt University, Rosenthal is the director of the Vanderbilt Institute of Nanoscale Science and Engineering and has served in that role for the past 12 years. During her tenure, the program has grown from 24 to 55 faculty members who have been awarded more than $250 million in funding for nanoscience research at the university. [8] The efforts of the Institute have also served to benefit opportunities and access to education in the field nanoscience education at the level of both undergraduate and graduate studies at Vanderbilt. At her undergraduate alma mater Valparaiso University, Rosenthal serves as a member of the Valparaiso University College of Arts and Sciences National Council. [9]

Rosenthal's independent research career has been largely focused on the development of nanomaterials for applications in the energy sciences and the biosciences. She has also notably been one of the earliest advocates and leaders in support of utilizing (and extending capabilities) in electron microscopy for the purpose of advancing understanding of structure-function relationships relevant to the design of nanomaterials towards targeted technological applications.

Quantum dots (QDs) or semiconductor nanocrystals are semiconductor particles a few nanometres in size with optical and electronic properties that differ from those of larger particles via quantum mechanical effects. They are a central topic in nanotechnology and materials science. When a quantum dot is illuminated by UV light, an electron in the quantum dot can be excited to a state of higher energy. In the case of a semiconducting quantum dot, this process corresponds to the transition of an electron from the valence band to the conductance band. The excited electron can drop back into the valence band releasing its energy as light. This light emission (photoluminescence) is illustrated in the figure on the right. The color of that light depends on the energy difference between the conductance band and the valence band, or the transition between discrete energy states when the band structure is no longer well-defined in QDs.

<span class="mw-page-title-main">Nanochemistry</span> Combination of chemistry and nanoscience

Nanochemistry is an emerging sub-discipline of the chemical and material sciences that deals with the development of new methods for creating nanoscale materials. The term "nanochemistry" was first used by Ozin in 1992 as 'the uses of chemical synthesis to reproducibly afford nanomaterials from the atom "up", contrary to the nanoengineering and nanophysics approach that operates from the bulk "down"'. Nanochemistry focuses on solid-state chemistry that emphasizes synthesis of building blocks that are dependent on size, surface, shape, and defect properties, rather than the actual production of matter. Atomic and molecular properties mainly deal with the degrees of freedom of atoms in the periodic table. However, nanochemistry introduced other degrees of freedom that controls material's behaviors by transformation into solutions. Nanoscale objects exhibit novel material properties, largely as a consequence of their finite small size. Several chemical modifications on nanometer-scaled structures approve size dependent effects.

Blinking colloidal nanocrystals is a phenomenon observed during studies of single colloidal nanocrystals that show that they randomly turn their photoluminescence on and off even under continuous light illumination. This has also been described as luminescence intermittency. Similar behavior has been observed in crystals made of other materials. For example, porous silicon also exhibits this affect.
