The 27th Inorganic Alumni Symposium was held on Friday, September 29, and included invited speakers Dr. David Dye, scientist at NSWC Crane Division; Prof. Skye Fortier, assistant professor at the University of Texas, El Paso; Dr. Linfeng Gou, associate scientist at Quaker Chemical Corp.; and Dr. Roger Kuhlman, scientist at Dow Chemical Co. The 8th Annual Watanabe Symposium in Chemical Biology was held on Saturday, September 30 and, this year, had the theme of biomolecular machines. Guest speakers included Prof. Angela Gronenborn from the University of Pittsburgh, Prof. Taekjip Ha from Johns Hopkins University and the Howard Hughes Medical Institute, Prof. Jody Puglisi from Stanford University, and Prof. Robert Sauer from the Massachusetts Institute of Technology. Lectures from these distinguished speakers were augmented by excellent presentations from our own Profs. Stephen Bell and Michael VanNieuwenhze. Through the National Science Foundation Major Research Instrumentation Program, we were fortunate to receive two awards this year to acquire new instruments for Chemistry. Prof. Lane Baker spearheaded a proposal for a nanoimprint lithography instrument, and Dr. Jonathan Karty led a successful effort for a high resolution gas chromatograph–mass spectrometry instrument. Our Research Experience for Undergraduates (REU) Program also sponsored by NSF continued in summer 2017. Ten undergraduates from across the United States participated in this highly competitive 9-week program, focused on nanoscale assembly of molecules and materials. The REU students along with graduate students and postdoctoral fellows from the department presented their research at the 4th Annual Symposium on Materials Research. The Symposium was highlighted by a keynote lecture given by Dr. Nelson M. Felix from the IBM Corporation. The College of Arts and Sciences at IU has developed a strategic plan to guide and direct research and teaching over the next decade. The College is now working on an implementation plan to set into motion what is outlined in the strategic plan. We hope the combination of the strategic and implementation plans will bring new research and instructional opportunities to Chemistry. In parallel, the department underwent an external review in spring 2017. Prof. Lane Baker did an outstanding job of coordinating the external review and devoted an inordinate amount of time preparing the review and response documents. Overall, the review was a positive experience and provided a chance for us to reflect on the state of the department and to receive feedback from the external review committee on what we do well and on areas we need to improve. We have now begun to work on many of the suggestion made during the review. As many of you know, fluctuations in funding from the university, state, and federal agencies continue to impact our ability to educate the next generation of chemists and keep our department at the forefront of research. The entire department and I are extremely grateful for your continued and generous support. Without the contributions of our alumni, friends, and colleagues, we would certainly struggle to meet our research and educational goals. This fall, we launched a new website for Chemistry, so please check out the latest news and information about the department at http://www.chem.indiana.edu/.

3 IU chemist could reduce nuclear waste with chemically-engineered molecules

Indiana University scientists report new, highly accurate method to predict effectiveness of molecules that extract toxic elements from the environment

discovery by Indiana University researchers could advance Athe long-term storage of nuclear waste, an increasingly burdensome and costly task for the public and private agencies that protect people from these harmful chemicals. In a recent study, the scientists report they have developed a new chemical principle with the potential to revolutionize the creation of specially engineered molecules that extract radioactive elements from nuclear waste, significantly reducing the volume of these dangerous materials. The method is also applicable to molecules created to extract chemical pollutants from water and soil. “This work represents a major step forward in the effort to engineer specially designed nanostructures by providing a new, highly accurate method to predict how these molecules will behave in solution,” said lead author Amar Flood, a professor in the IU Bloomington College of Arts and Sciences’ Department of Chemistry. The breakthrough is reported in a cover article in the journal CHEM [DOI.org/10.1016/j.chempr.2017.08.003].

Flood said the study addresses the fact that it is nearly Professor Amar Flood impossible to predict how efficiently an engineered molecule will perform in the real world. This is because chemists can water – a part of the process used to convert seawater into currently only design molecules to function in isolation, despite freshwater – to eliminate excess chemical fertilizers from soil, or the fact that molecules exist in combination – or “in solution” to gather lithium ions used in renewable power. – with other molecules. Salt water, for example, is a solution of salt in water. With the methods reported in the paper, Flood said, chemists can start to design new molecular reactions with the end goal He compared the situation to designing a machine in outer space in mind. Specifically, the new principle finds that the attraction and then placing it at the bottom of the ocean. The waterlogged between receptor molecules and negatively charged ion device will not function the same as the original design. molecules is based on the dielectric constant of the solvent in which they’re combined. A dielectric constant is a measurement This is especially serious because creating artificial molecules of a substance’s ability to stabilize electrical charge. to serve a specific function requires extremely precise design – like building a lock to fit a key. For example, a special molecule To test their method, the IU team applied their newly developed developed by Flood’s lab, called a cyanostar, consists of a five- chemical principle to triazolophane – a molecule designed to sided star-shaped lattice of carbon and nitrogen atoms with extract chloride from surrounding molecules – in combination an empty center – the “lock” – whose specific shape causes with chemical solvents commonly used in reactions to remove negatively charged molecules such as phosphates and nitrates unwanted ions from other liquids. In each case, the principles – the “key” – to catch in the center and break off from their discovered by Flood’s group accurately predicted the molecules’ previous host. If the solution fills up or warps the lock, the key effectiveness. might no longer work. The primary researcher responsible for the method is Yun Liu, a Structures such as the cyanostar are also known as “receptor Ph.D. student in Flood’s lab. molecules” because they are specially designed to receive specific molecules. In addition to accomplishing nuclear waste “The current paradigm only works for molecular designs on reduction, this technology may be used to remove chloride from the drawing board, in theory, “ Liu said. “But we want to make

4 molecules that will work in practice to help solve problems in the real world.” The team also noted that the ability to accurately predict how a molecule will function in solution will assist in the development of highly accurate computer simulations to rapidly test chemically engineered molecules designed to achieve specific effects. Additional authors on the paper were Professor Krishnan Raghavachari and Ph.D. student Arkajyoti Sengupta, both in the IU Bloomington Department of Chemistry, who were responsible for the study’s computational component. This research was supported by the U.S. Department of Energy. This story was written by Kevin Fryling and is reprinted by permission.

For the past several semesters, Laura Brown, Senior Lecturer, in These limitations meant that students would be creating a small the Department of Chemistry, has informally surveyed students library of compounds, catalysts, or molecules and setting up of her upper level Organic Chemistry laboratory course on their reactions to occur until the next lab session. Brown then went to participation in research. Through these surveys, Brown found colleague and biologist Julia van Kessel whose complimentary that a sizable portion of students were missing out on gaining skillset would aid in developing a CURE within these confines. valuable research experience. The collaboration yielded a way for students Sixty percent of students are NOT to systematically test for certain proteins. involved in any form of research.

For assessment, Brown used the CURE Survey A traditional research experience would which was produced by collaborative efforts have students working closely with from professors at Grinnell College, Hope faculty or AI’s in their lab. Despite the College, Harvey Mudd College, and Wellesley impracticality of getting Chemistry’s 400- College. Students took this self-reporting some majors into labs, Brown wondered survey as both pre-course and post-course what factors were causing so many surveys. students to miss these opportunities. The surveys shed light on two major What did these surveys reveal? Senior Lecturer Laura Brown reasons: Students reported improvements in skills such 1. First generation students are unaware of the informal as reading the primary literature. However, the process of getting involved, which requires knowing what percent of students interested in pursuing a graduate degree had they want to do and approaching a faculty member about it. more than doubled in between surveys. 2. Students who work part-time jobs while in school are That’s pretty good evidence that they identify as a scientist more often unable to take time beyond their class schedule for at the end of the class than they did at the beginning. research experience. Last semester, student experiments found a compound which A solution to both issues, Brown thought, would be to provide showed a viable response. Now that they have found something these experiences as a course where all students would have that works, future CUREs can direct their modifications to the opportunity to participate. This is where CURE comes into incrementally build off of those findings. In the future, Brown play.

One of these benefits is retaining permission. students in their particular degree, which is accomplished by increasing their self-identification as a scientist. Students sign up for a CURE as they would any other course in a list of offerings. In return, they receive course credit and have built-in lab time in their schedules for running experiments. These time restrictions, however, present their own set of difficulties when developing a CURE: 1. Labs typically meet 4-5 hours once per week and few experiments require a week for incubation. 2. Ensuring the research project is not so complex that inexperienced students cannot participate.

said. “Although the preparation we are receiving through our individual programs at IU Bloomington is superb, I feel that it is important to gain as much hands-on teaching experience as possible. The more hands-on teaching experiences I can have, the better able I will be to serve a university and my future students as a professor.” With nearly 140 students enrolling each summer, the program caters to a wide range of learning abilities. They see students who need additional help in specific academic areas as well as students who are passionate about a subject and looking for ways to learn more, Hummels said. Because of this, the instructors make a point of actively engaging the students rather than lecturing the full two hours, and class Gabby Norris (sophomore at Bloomington High School North) and Alyssa Gilliland (sophomore at Edgewood High School), participates in a chemistry sizes are capped at 15 students. is one of the courses offered through the Foundations in Science and Mathematics program.

The difficult subject matter and the large amount of content being taught in high school are compounded by the fact that science and math concepts build off one another, and some students can get left behind quickly, she said. The program isn’t just a learning opportunity for the high school students, however. The graduate students, who do everything from applying for funding to designing the curriculum to teaching the courses, are expanding their knowledge as well.

11 IU chemists create molecular ‘leaf’ that collects and stores solar power without solar panels This new molecule harvests sunlight to create useable material from carbon dioxide in the atmosphere

An international team of scientists led byLiang-shi Li at Indiana University has achieved a new milestone in the quest to recycle carbon dioxide in the Earth’s atmosphere into carbon-neutral fuels and others materials. The chemists have engineered a molecule that uses light or electricity to convert the greenhouse gas carbon dioxide into carbon monoxide – a carbon- neutral fuel source – more efficiently than any other method of “carbon reduction.” The process is reported today in the Journal of the American Chemical Society. “If you can create an efficient enough molecule for this reaction, it will produce energy that is free and storable in the form of fuels,” said Li, associate professor in the IU Bloomington College of Arts and Sciences’ Department of Chemistry. “This study is a major leap in that direction.” Burning fuel – such as carbon monoxide – produces carbon dioxide and releases energy. Turning carbon dioxide back into fuel requires at least the same amount of energy. A major goal among scientists has been decreasing the excess energy needed. Professor Liang-shi Li This is exactly what Li’s molecule achieves: requiring the least amount of energy reported thus far to drive organic compound known as bipyridine – triggers a the formation of carbon monoxide. The molecule – a highly efficient reaction that converts carbon dioxide to nanographene-rhenium complex connected via an carbon monoxide. The ability to efficiently and exclusively create carbon monoxide is significant due to the molecule’s versatility. “Carbon monoxide is an important raw material in a lot of industrial processes,” Li said. “It’s also a way to store energy as a carbon-neutral fuel since you’re not putting any more carbon back into the atmosphere than you already removed. You’re simply re-releasing the solar power you used to make it.” The secret to the molecule’s efficiency is nanographene – a nanometer-scale piece of graphite, a common form of carbon The new molecule employs a nanographene complex (on left) to absorb light and drive (i.e. the black “lead” in pencils) – because the conversion of carbon dioxide (upper center) to carbon monoxide (on right). the material’s dark color absorbs a large Photo by Ben Noffke and Richard Schaugaard amount of sunlight.

Li said that bipyridine-metal complexes have long been liquid form, since solid catalysts are easier to use studied to reduce carbon dioxide to carbon monoxide in the real world. He is also working to replace the with sunlight. But these molecules can use only a tiny rhenium atom in the molecule – a rare element – with sliver of the light in sunlight, primarily in the ultraviolet manganese, a more common and less expensive metal. range, which is invisible to the naked eye. In contrast, the molecule developed at IU takes advantage of the All of the research on the study was conducted at IU. light-absorbing power of nanographene to create a The first authors on the paper areXiaoxiao Qiao and reaction that uses sunlight in the wavelength up to Qiqi Li, former graduate students at IU.

The idea to link nanographene to the metal arose from Li’s earlier efforts to create a more efficient solar cell This story was written by Kevin Fryling and is reprinted by with the carbon-based material. “We asked ourselves: permission. Could we cut out the middle man – solar cells – and use the light-absorbing quality of nanographene alone to drive the reaction?” he said. Next, Li plans to make the molecule more powerful, including making it last longer and survive in a non-

Highlights include the paparazzi that hounded the Laureates, people stopping them on the street for autographs, and the Laureates getting a standing ovation at the end of their Nobel lectures. Keeping with the theme of the Nobel Prize, molecular switches and machines were made in the Flood Group in new works by Chris Benson and by Bo Qiao. The first made use of redox chemistry to switch a small organic radical in and out of the centers of the cyanostar macrocycles. The second made use of acid-base to drive movements of the macrocycles along an axle in rotaxanes – a class of mechanically active molecules whose name is derived from the Latin for wheel (rota) and axle (axis). These studies lay an exciting foundation for making molecular machines capable of moving down molecular tracks in the future.

She also began as an Associate Editor for Nanoscale, a journal of the Royal Society of Chemistry that publishes research across nanoscience and nanotechnology. Her group continues to develop new ways of making nanoscale materials with structural precision. This work produced a manuscript in Nanoscale (DOI: 10.1039/ C6NR04085C) which reports the highest refractive index sensitivity for gold-based nanomaterials which scatter and absorb light in the visible region. This enhancement was achieved by incorporating palladium into gold nanomaterials with the appropriate shape, and these structures could bring improvements to colorimetric sensing applications. In fact, graduate student Josh Smith is collaborating with former graduate student, and current scientist at the Naval Surface Warfare Center Crane Division, Alison Smith to use these nanomaterials in anti-tamper and anti-counterfeit applications for secured electronics. The idea of using nanomaterials in these applications was highlighted in a Provost Professor Jeffrey Zaleski 2017 manuscript from the Skrabalak group in Journal of Jeff Zaleskiis a professor of chemistry with Materials Chemistry C (DOI: 10.1039/C7TC00080D).

Bruce was a lover of all creatures — large and small. He raised farm animals and even a few wild ones. Many of the dogs in Unionville also knew Bruce well, as he always kept some dog biscuits in his vehicle and would stop to give them one. His own dogs were either riding or running alongside of his golf cart.

His grandson, Samuel, was born in 2016 to his son, John, and daughter in-law, Hillary, and was a source of great pride and joy. He was also close to his three brothers Mark, Perry, Kent, their wives and children; family was important to Bruce.

He was a great friend and mentor. The things that Bruce built and repaired in his life particularly for others are innumerable. His quote “Never underestimate the impact you have on the lives of others” truly describes the amazing man we knew.

In Memorium: Richard Robert “Dick” Otter May 17, 1920 - March 6, 2017 NOTRE DAME - Richard Robert “Dick” Otter, 96, died peacefully at 9:50 p.m. Monday, March 6th, at Dujarie House, Notre Dame. Born May 17, 1920, in Evanston, IL, to the late Irene (Farrell) and William Otter, Dick was a longtime South Bend resident. After graduating from Dartmouth College, Dick earned a PhD in chemistry at Indiana University in Bloomington. There he fell in love with mathematics and with the woman whom he would later marry, Margot Weichert. After their wedding in 1949 Dick and Margot settled in South Bend, where Dick joined the mathematics faculty at Notre Dame. He taught there Dick Otter, ca. mid-1940s. His time at IU had a great until his retirement in 1985. influence on the course of his life, and I hope there are some who still remember him. Dick was an avid hockey player and competitive sailor. His love of sailing began as a teenager racing Star boats with his brother on Lake Michigan. Later he was instrumental in the growth and success of the Eagle Lake Sailing Club in Edwardsburg, MI. In 1969 Dick helped establish the Irish Youth Hockey League and was one of its first coaches. For many years he was a regular in the noontime hockey group at Notre Dame, and continued to play beyond the age of 80. He was preceded in death by his loving wife Margot, as well as by a sister, Josephine Gerlin, and a brother, Bill Otter. He is survived by his children, Marlene Hubbard

The origins of most of the signals we were finding and by John Hayes interpreting were in the oceanic water column (where the producer organisms grew) and in ocean sediments (where a microbial I arrived in Bloomington in 1970, fresh from a postdoctoral community chewed on organic materials prior to their ultimate appointment in Bristol, England. I joined the faculty as a mass burial). In conversations with prospective graduate students, I used spectroscopist and analytical chemist, but my postdoc had been to tell them “I could die happy if, when a molecule of CO2 dissolved in organic geochemistry and much of my interest in chemistry in seawater was assimilated by an alga and used to produce organic developed from my parallel interests in earth science. The central matter, I could predict whether that carbon would be reoxidized or problem in organic geochemistry is to understand the history instead buried in the seafloor.” We were getting close. I worked of the molecules that can be extracted from sediments. What often with oceanographers and was a frequent visitor at Woods organisms produced them?

Remarkably, physical organic chemistry, I had heard about isotope effects in the whole thing runs on “soft money,” with members of the staff which the rate of a reaction or position of an equilibrium is affected writing proposals furiously to cover not only all the usual research by isotopic substitution. When I asked whether such phenomena expenses but also 100% of their annual salaries. You would could produce misleading results in tracing experiments, I was told, think that wouldn’t make it very attractive but, by providing a perfectly accurately, “The isotope effects can’t be avoided but the truly excellent research environment, the institution maintains a isotopic separations that they produce are much smaller than the strong staff. Combined, they mount a broad and incisive attack on variations imposed by the tracers.” problems like the carbon cycle and its role in climate change. I kept thinking about that.
