Dr. Kazuo NakamotoDr. Kazuo Nakamoto




Nakamoto's Biography

Kazuo Nakamoto was born in Kobe, Japan. He received his B.S. and D.Sc. from Osaka University and remained at Osaka as a member of the faculty for an additional four years, except for the two years which he spent at Iowa State University working in the laboratory of Robert E. Rundle as a Fulbright Scholar. In 1958 he joined the faculty at Clark University, moving to Illinois Institute of Technology in 1961 and in 1969 he became the first Wehr Professor of Chemistry at Marquette University.

Professor Nakamoto directed the research of more than 85 graduate students and postdoctoral associates and published more than 210 papers and 15 review articles. He was a pioneer in the use of metal isotopes to elucidate the involvement of metals in low frequency vibrations in metallic complexes, a discovery that helped fuel the rapid growth in the developing field of bioinorganic chemistry. He then turned his attention to biological problems and began a vigorous research program dealing with heme-related compounds. He was also amongst the first to use matrix isolation techniques to prepare and characterize unstable species, including the biologically relevant ferryl heme complexes, an important intermediate in many oxidative heme enzymes. His interest also included DNA and the process of intercalation. Using oligonucleotides synthesized to include specific sequences, he established criteria that can be used to deduce the site specificity of these compounds. He was able to differentiate between exterior (groove) binding and interior (intercalation) binding through careful vibrational analysis.

In keeping with his life-long interest in communicating the excitement of science, he authored several influential texts in the field of spectroscopy, including his very famous 2-volume work on Infrared and Raman Spectra of Inorganic and Coordination Compounds, the sixth edition of which was issued in 2009, and in 2008 coauthored a new book entitled Drug-DNA Interactions: Structures and Spectra. Remarkably, his passion for science and dedication to accomplishment were clearly manifested, even up to the final weeks of his life, as he was continually pondering new points to include in planned future editions of his books. In spite of his great scientific success, he remained a genuinely modest man who will long be missed by the many of us who knew and admired him.

Dr. Rajendra RathoreDr. Rajendra Rathore




Rathore's Biography

Rajendra Rathore, Pfletschinger-Habermann Professor of Organic Chemistry at Marquette University, unexpectedly passed away on February 16, 2018, following a brief battle with respiratory disease. Dr. Rathore was a devoted husband and loving father to two daughters, and had a zeal for life that was embodied in his passion for his family, as well as for his science.

Professor Rathore received his M.Sc. in 1986 from the Indian Institute of Technology (IIT)-Kanpur and earned his Ph.D. in Organic Chemistry from the University of Western Ontario in London, Canada in 1990. He was a post-doctoral research associate (1992-1997) and a visiting assistant professor (1997-2000) at the University of Houston under the supervision of Dr. Jay K. Kochi. He joined the faculty at Marquette University in August 2000.

Dr. Rathore made key contributions to the areas of organic supramolecular and materials chemistry. He was particularly interested in the rational design and synthesis of novel electro-active molecules with applications in molecular recognition, photovoltaics, and molecular electronics. His recent work demonstrated that frontier molecular orbitals can be applied in the design and synthesis of novel electro-active species, akin to their well-known application in the rationalization of pericyclic reactions.

During Dr. Rathore’s incredibly distinguished career, he has published more than 150 articles in various respected journals, including Science, Journal of the American Chemical Society, and Angewandte Chemie. He has an h-index of 35, and his research papers have been cited more than 3,700 times. Dr. Rathore’s incredible passion for research and science will live on through the Raj Rathore Memorial Lecture and annual Raj Rathore Memorial Scholarship. Donations to the Rathore Memorial Fund can be made online.

Ryan's Biography

Professor Ryan obtained his B.S. degree in 1969 from the University of Notre Dame and his Ph.D. in 1973 from the University of Wisconsin. His interest in electroanalytical chemistry led him to a postdoc at the University of Arizona before joining the faculty here in 1974. He also took a sabbatical leave at the University of Iowa with D. Coucouvanis (1981-82), and the University of Paris VII with J.-M. Saveant (1995-96).

The primary aim of his research has been to investigate multi-electron reactions that occur either in solution or at the electrode surface. This has led to the study of two important systems: 1) the multi-electron reduction of iron nitrosyls to hydroxylamine/ammonia, and, 2) the electrochemistry of electroactive materials in room temperature ionic liquids (RTILs). The first system has been observed in nature with the assimilatory and dissimilatory nitrite reductases. The assimilatory nitrite reductases contain a unique heme group, called a siroheme (a derivative of tetrahydroporphines), while the latter reductase often contains heme d1, a porphinedione. Using UV/visible and infrared spectroelectrochemistry, the effect of the macrocycle on the redox properties of the metalloporphyrin derivative, and its nitrosyl complex was studied, and interpreted using DFT calculations. The primary focus of the work now is the identification and characterization of the protonated iron nitroxyl complex (Fe(P)(HNO)). This species is an important intermediate in many biological processes. By combining electrochemical methods with spectroscopy, important intermediates can be identified using UV/visible and infrared spectroscopy. In addition, isolation and characterization of important species have been carried out using NMR, resonance Raman and x-ray methods. The second area of research has been the investigation of redox species in RTILs. The ionic nature of the solvent provides unique opportunities for the interaction of the redox products with the solvent, sometimes collapsing two separate reductions into a single wave. The RTILs have some very important properties that make them useful in chemistry, but their high viscosity and high cost can limit their applications. Mixtures of RTILs with molecular solvents provide a way to overcome these problems. One important aspects of molecular solvent/RTIL mixtures is that they are not homogeneous on the nanoscale. Even at relatively low concentrations of an RTIL, aggregates of RTIL species form and are able to solvate ionic species, leading to reactivity more closely related to the RTIL. The focus of his work has been to understand these interactions so that they can be used to make more efficient redox/catalytic systems with lower costs and solution viscosity.

Professor Emeritus




Schrader's Biography

Professor Schrader obtained his B.S. from Iowa State University and earned his Ph.D. degree in 1961 from the University of Minnesota. His interests in theoretical chemistry led him to a research fellowship at Columbia University and the IBM Watson Laboratory. In 1963, he accepted a position as assistant professor in the chemistry department at the University of Iowa. Professor Schrader joined the faculty at Marquette in 1968. He became Research Professor in 1996 and Professor Emeritus in 2017. He passed away on August 15, 2023.

His research focused on the quantum theory of atomic and molecular structure, especially systems interacting with positrons or positronium atoms, both bound and scattering states.

The positron is the antiparticle of the electron. It sometimes called and thought of as "exotic," but it is the most common of the uncommon particles. It is easily, safely, and conveniently obtained for laboratory experiments in the form of a beta-emitter such as sodium-22. It is a unique probe for many chemical systems, and has proven valuable in industry as a tool for characterizing polymers, semiconductors, alloys, surfaces, coatings, and so forth. It has a rich chemistry, both in the gas and liquid phases.

The positron annihilates in ordinary matter with a lifetime of about a nanosecond, which is a long time on most chemical scales (for example, air molecules vibrate a million times in a nanosecond). A positron can form a neutral atom with an electron. This atom, called "positronium," has a mass of about 0.0001 Daltons. It has all the states of the hydrogen atom but they are only half as deeply bound.

He has been calculating wave functions for compounds of positronium, Ps, for many years. The simplest of these is PsH, positronium, which consists of two electrons, a positron, and a proton. There are many other compounds.

He is currently writing a full-length book on the history of atomic energy.
