The Department of Chemistry and Biochemistry takes great pride in an-nouncing that Dr. R. Stanley Wiliams will be awarded the 2007 Glenn T. Sea-borg Medal. The award, established in 1987, celebrates outstanding achieve-ment in chemistry and biochemistry.

Stan is an HP Senior Fellow at Hewlett-Packard Laboratories and founding Director (since 1995) of the HP Quantum Science Research (QSR) group.

Harold G. Martinson

Chair’s Message

I am delighted once again to be able to begin my newsletter message by welcoming a new faculty member! Margot Quinlan will be joining us as an assistant professor on July 1, 2008. Margot will be the inaugural holder of a newly endowed, five year term chair—the Alexander and Renee Kolin Endowed Professorship of Molecular Biology and Biophysics.

As a graduate student at Penn, Margot focused on the fascinating mechanism of force production by the molecular motor protein, myosin. Myo-sin generates force in muscle cells, and shuttles cargo around cells by moving along actin fi laments. Myosin grasps an actin fi lament using two arms, and Margot asked whether the myosin then moves along the actin in an inch worm fashion or instead by a stepping motion. To answer this she developed a novel microscope that can monitor changes in fl uorescence polarization in real time and thereby monitor the orientations of single molecules as they move. She found that myosin employs a human-like walking motion to move along fi la-ments of actin.

As a postdoctoral fellow at UCSF Margot shifted her focus to actin—and to cell biology, where she studied the mechanisms regulating the dynamic assembly and disassembly of actin fi laments in the cell. Actin fi laments, as major components of the cytoskeleton, give the cell its shape, help it to move, and provide for intracellular transport. Margot scored a major discovery here by identifying “Spir,” which regulates

the assembly of actin fi laments and which, even at the earliest stages of embryogenesis, is vital for establish-ing the proper polarity of the embryo. Margot plans to expand her research on Spir when she sets up her independent research program here at UCLA.

Congratulations to Yung-Ya Lin! Promoted to associate professor as of July 1st this year, he is a formidable addition to the tenured ranks of this department. As a teacher Yung-Ya is second to none, inspiring passionate and eloquent praise from students at all levels. In research Yung-Ya is best known for creating entirely new ways of thinking about complex issues—issues that others have thought about for de-cades. Yung-Ya works at the interface of sophisticated physical chemistry and cutting-edge medical imaging. Everyone knows that nuclear magnetic resonance (NMR) is a classic part of physical science, having long played a cornerstone role in the determination of molecular structure. More recently, it has occupied center stage as the basis for magnetic resonance imaging (MRI) in medicine.

Yung-Ya’s research has introduced a totally new and powerful approach to MRI. Through a combination of theory and experiment, he has harnessed non-linear nuclear spin dynamics to enhance both sensitivity and contrast. Essentially all monographs and all cur-rent NMR characterizations and MRI applications deal exclusively with the linear nature of spin dynamics. The basic idea of Yung-Ya’s research has been to control the chaotic behavior of spins that is caused by non-linear ef-fects such as “radiation damping” and “distant-field” interactions. Yung-Ya has exploited these effects to enhance contrast and make possible earlier and surer detection of cancer tumors and disease lesions. This approach has already been tested in mice with very promising results.

In closing, I would like to provide an update on two events reported in the Spring 2006 Newsletter and an inter-esting connection between them. The

fi rst of these events was the two-day remembrance of Chris Foote, which included science, music, and a banquet in October of 2005. Chris Foote was a faculty member at UCLA for over forty years, and he created the fi eld of singlet oxygen organic chemistry that is of great importance to atmospheric, materials, and biological chemistry. As Chair of our department and contributor to numerous university activities, as well as an outstanding teacher and textbook author, he positively infl uenced every aspect of our university community. Moreover, our department continues to benefi t enormously from the generos-ity of the late Chris Foote and his wife, Judi Smith, who, together with a host of their colleagues, friends, and former students endowed the Christopher S. Foote Graduate Fellowships in Organic Chemistry. As described on page 5, the fellowships support outstanding students during their graduate careers and help UCLA attract the best to our department.

I mentioned that there were two events from the Spring 2006 Newslet-ter that deserved updates, and that there was an interesting connection. The second event was the arrival of Omar Yaghi, who came to us from the University of Michigan. Omar is one of the most highly cited chemists in the world today and was recently selected as one of Popular Science Magazine’s “Brilliant 10” scientists and engineers in the nation. Omar has already had a tremendous impact on UCLA and the California NanoSystems Institute, where he is director of the Center for Reticular Chemistry. The connection is that an endowed chair was estab-lished specifi cally for Omar, and it was named the Christopher S. Foote Chair of Chemistry and Biochemistry.

Thus, the Foote Fellowships for superior graduate students and the Foote Chair for outstanding faculty will perpetuate our memories of Chris’ contributions and achievements now and forever into the future.

3UCLA Chemistry and Biochemistry l Fall 2007

The Biochemistry Division is cur-rently raising funds to endow six faculty chairs in the names of our emeriti. It is hard to imagine a chemistry de-partment without biochemists, but a generation ago, biochemistry was not taken seriously by most chemists.

A few insightful pioneers within our department persevered and as-sembled what is now considered one

of the top biochemistry divisions in the world. While helping to create a new fi eld, two became members of the Na-tional Academy of Sciences, one built a major pharmaceutical company, and one brought a Nobel Prize to UCLA. All made major discoveries, and all enhanced the lives of their colleagues and their students.

We would like to honor their impor-

tant contributions to science, teaching and the department by creating chair positions in each of their names: Dan Atkinson, Paul Boyer, Richard Dickerson, Roberts Smith, Verne Schumaker and Charlie West.

For more information please contact Robert Wise: [email protected].

Rebecca Nelson, together with her graduate mentor David Eisenberg, will receive the American Chemical So-ciety’s 2008 Nobel Signature Award at the Society’s annual meeting next April in New Orleans. This award recognizes her dissertation as highly distinguished. The work is being published in a series of research papers and reviews. Two of the papers appeared in the journal Nature while two reviews appeared in Advances in Protein Chemistry and Current Opinion in Structural Biology, respectively.

Rebecca’s work is on the atomic structure of the amyloid state–the fi bril state of proteins associated with various diseases including Alzheimer’s and Parkinson’s. The structure of the amyloid state has resisted elucidation because fibrils are not well enough ordered to crystallize.

Fortunately, in 2001 UCLA Chem-istry graduate student Melinda Bal-

birnie found that only seven residues hold protein molecules together in a particular yeast amyloid and was able to grow tiny crystals of this segment. Rebecca went on to determine the structure using X-ray diffraction, aided by her coworkers, David Eisenberg, and Staff Research Scientist Michael R. Sawaya. Because the crystals were exceptionally small, the scientists had to travel to the European Synchrotron Radiation Facility in Grenoble, France, to use specialized equipment.

What Rebecca and her cowork-ers found was that the amyloid state consists of two beta sheets, with tightly interdigitating sidechains, and no water between the sheets. The team calls this type of structure, not seen before in proteins, the “dry steric zipper.”

The ACS Nobel Laureate Signature Award for Graduate Education in Chem-istry was established in 1978 and is the highest honor accorded to a graduate

UCLA Chemistry and Biochemistry l Fall 20074

Marjorie Bates Retires“Margie” Bates, Senior Lecturer

in Biochemistry, has retired after almost 20 years with the department. More than 60 people attended a reception in her honor in the Winstein Café Com-mons on July 11th.

Margie was an occasional lecturer for the department from 1987-93 after which she took a hiatus. She returned in 1995 as a full-time lecturer with more

than 1000 students each year.Sylvia Daoud Kinzie, one of her

former TAs, writes, “I knew Dr. Bates in the capacity of a mentor while working as a TA...I consider Margie to be one of my greatest mentors and hold her very dear to my heart. She set the standards very high for both her students and TAs and by doing so inspired us to rise to the occasion and be the best we can be.”

Margie constantly sought new ways to engage her students and to make her large classes interactive and stimulating. She developed elaborate animated computer illustrations of com-plex processes, collaborative learning and problem solving sessions (CLAPS), analogies, “micro-discussions” (in which students talked over questions raised in class), imaginative and en-tertaining classroom demonstrations, original biochemistry songs, ungraded diagnostic quizzes, a 180-page course compendium (also used as a class note-book), and a 164-page problem book.

The recipient of many teaching

awards, including the University Dis-tinquished Teaching Award, Margie believes the most important aspect of a college education is the development of analytical and critical thinking. Her classes gained a reputation for be-ing extremely diffi cult, although many students loved her teaching style and recommended her class to friends.

As departmental liaison during her last year at UCLA, Margie wrote part of the Departmental Review Statement on behalf of the instructional faculty, worked to enhance the instructional faculty’s image and departmental role, and spearheaded the establishment of the new Instructional Division as an of-fi cial division of this department.

“I’d like to send my thanks to all who helped to make the July 11th reception such a joyous occasion and contributed to the generous gifts,” Bates says. “I especially want to express my deep appreciation to the staff, faculty, and teaching assistants who helped and supported me over the years.”

On the occasion of Christopher Foote’s 70th birthday, his former co-workers and faculty members at UCLA created the Christopher S. Foote Grad-uate Fellowship in Organic Chemistry. Chris and his wife, Judi Smith, made a generous bequest that fully funded the fellowship in 2005.

Chris, an outstanding colleague in our department for more than 40 years, died in 2005. His loss was felt throughout our community as he had a positive infl uence on every aspect of our department. UCLA is fortunate to benefi t from Judi’s continuing outstand-ing leadership and service as Professor of Physiological Science/Neuroscience

Foote Graduate Fellowships Establishedand the UCLA Vice Provost for Under-graduate Education.

The Foote-Smith gift allows our department to award fellowships to the most promising applicants to our graduate program, to further improve the quality of our outstanding graduate program, and to keep Chris close in our memories.

The four Foote Fellows are Karina Heredia, Gregory Glover, Khin Chin and Jason Spruell. Karina’s research with Heather Maynard focuses on con-trolled radical polymerization techniques to create protein-polymer bioconjugates for applications in biotechnology and medicine. Greg is also in the Maynard

lab, and is focusing on the synthesis and application of protein-polymer conjugates for use as therapeutics and materials. Khin began research in organic chemistry as an undergraduate at UCLA in the lab of Chris Foote. His graduate research with Miguel Garcia-Garibay centers on the spectroscopy of solid-state nanocrystalline systems and the photophysics of novel fullerene derivatives. Jason is Fellow in the NSF Materials Creation Training Program as well as a Foote Fellow. He works with Fraser Stoddart and Ken Houk, developing nanomachines and molecu-lar muscles.

UCLA Chemistry and Biochemistry l Fall 20076

The Department of Chemistry and Biochemistry has a long history of shared instrumentation facilities op-eration where large, complex, and expensive instrumentation is made available to researchers based on need. In recognition of the increasingly multi-disciplinary nature of modern research and to increase visibility and access to modern instrumentation for molecular characterizations for the larger research community, the Department of Chem-istry and Biochemistry led the creation of the UCLA Molecular Instrumentation Center (MIC), a campus-wide core facil-ity. Of equal importance to instrument access is the availability of technical staff to provide operation, training, consulting, maintenance, and repair of the equipment. Dr. Jane Strouse, who has been developing shared instrumen-tation in chemistry and biochemistry for over twenty-fi ve years, serves as the Director of the MIC, with administrative assistance from Dr. Dafni Amirsakis.

The MIC Magnetic Resonance Laboratory together with the biostruc-tural NMR instruments includes one EPR and ten NMR spectrometers ranging in frequency from 300 to 800 MHz, which can be used to observe a large range of nuclei in liquid and solid samples over a large temperature range. Two full-time staff scientists, Dr. Robert Taylor and Dr. Ping Yang, and one half-time graduate student as-sistant, Gardner Creech, maintain the MIC instruments.

The J.D. McCullough X-ray Labo-ratory is made up of two single-crystal

diffractometers with low temperature capability and three powder diffrac-tometers with a variety of accessories, e.g. high temperature furnaces, an area detector, and autosamplers. Currently, the laboratory is operated by Dr. Saeed Khan, with active recruiting underway for a second staff member in X-ray diffraction.

The Mass Spectrometry Labora-tory contains a variety of instruments with several ionization methods and analyzers. Sample service is available or users may be trained to acquire their own mass spectra. This labora-tory has recently been reorganized and rearranged to optimize the space available. Currently, the staff is made up of one full-time mass spectrometrist,

Dr. Gregory Khitrov, and a half-time graduate assistant, Chris Henry. Active recruiting is underway for a second staff scientist and for a MIC associate direc-tor for Mass Spectrometry.

The Materials Characterization Laboratory consists of a scanning electron microscope, atomic force mi-croscope, light scattering particle ana-lyzers, thermal analysis equipment, and many more small instruments useful for materials synthesis and characteriza-tion. This laboratory is managed by Dr. Ignacio Martini.

The Proteomics Laboratory, man-aged by Dr. Melissa Sondej, is made up of electrophoresis equipment, a spot cutter, gel imagers, and several mass spectrometers. The Biochemistry Instrumentation Facility, maintained by Dr. Martin Phillips, has a substantial list of equipment for the physical char-acterization of biochemical systems. Elemental Analysis and Speciation, operated by Dr. Amir Liba, includes ICP-MS, ICP-OES, both with autosam-plers, HPLC, and an elemental analyzer for light elements. Sample preparation consultation and digestion services are available.

Funding for this endeavor has been provided by the Division of Physical Sciences and Life Sciences of the Col-lege of Letters and Science, the David Geffen School of Medicine, and the California NanoSystems Institute. The MIC web site contains an up-to-date equipment list along with full contact information for all staff. We invite you to have a look at www.mic.ucla.edu.

UCLA Chemists Develop a New Ultra-Incompressible, Superhard Materialby Ric Kaner

Superhard materials are used for everything from cutting tools to drill for oil and dig tunnels to scratch-resistant coatings for precision instruments. In a recent issue of the journal Science (316, 436, 2007), Ric Kaner, Sarah Tolbert, and their students, along with Jenn-Ming Yang from Materials Science and Engineering and Abby Kavner from Earth and Space Science, reported a promising new approach to designing ultra-incompressible, superhard ma-terials. Their idea is to combine dense transitional metals, which are often soft

due to metallic bonding, with small main group elements to form short, strong covalent bonds. This has led to rhenium diboride (ReB2), a material capable of scratching diamond.

Diamond is the hardest known material because its carbon atoms form very short covalent bonds, resulting in a material that is exceedingly resistant to plastic deformation. While diamond is an extremely useful abrasive, it does have limitations. For example, diamond is not used to cut steel due to reactions that occur between the carbon in dia-mond and the iron in steel. Other light elements, such as boron and nitrogen, can be combined to mimic the prop-erties of diamond by maintaining the short covalent bonds responsible for its high hardness. The result, cubic bo-ron nitride, is often used as a diamond substitute since it also has a very high hardness (although only half that of diamond) and it is capable of cutting steel. However, cubic boron nitride is not found in nature and must be made synthetically under extreme pressures and temperatures resulting in a mate-rial that is even more expensive than diamond. Hence, new materials that can be made under less extreme conditions are desirable.

To this end, the UCLA team has developed methods for making ReB2

without the need for pressure. Normally, rhenium is a soft metal, easily deformed by bending, as one would unfold a paper clip. However, rhenium is dense and quite incompressible. By incorporat-ing boron into the network of rhenium atoms, short covalent bonds form to create ReB2, a material that is both highly incompressible and very hard. In fact, in one direction rhenium diboride has been found to be as incompress-ible as diamond. Although its average hardness is considerably less than that of diamond, when oriented in the proper direction, ReB2 is capable of scratching diamond. Rhenium diboride has also been found to withstand the highest differential stresses ever measured (up to 12.9 GPa). The UCLA team is now trying to develop related materials that use less expensive transition metals.

This research is funded by the National Science Foundation. Special thanks are also due to alumni Ray and Dorothy Wilson and the late George Gregory and his wife Gerry who have generously supported Ric Kaner’s re-search over many years.

A fascination with soft materials and just about anything dispersed in a liquid drives the research of Tom Ma-son, the John McTague Chair. Since he joined our department about four years ago, Tom and his group have been mak-ing new kinds of multi-phase materials, including ‘LithoParticle dispersions’ and ‘nanoemulsions’, as he calls them.

LithoParticles, custom-shaped particles that range in size from mi-croscale to nanoscale, are made us-ing lithographic technology, the same technology used to create electronic circuitry for computer chips. Tom’s group is the fi rst on campus to install and operate an advanced lithography exposure system, known as a ‘stepper’. The stepper system uses robots, auto-mation, and ultraviolet light to rapidly

print very detailed patterns onto silicon wafer surfaces. Tom’s group applies this technology in unusual ways to mass-produce new kinds of particles and release them from a solid substrate into liquid solution. LithoParticles can be made from a wide variety of solid materials, including polymers, metals, and inorganics, and they can have a multitude of different shapes. A strik-ing example of LithoParticles recently made the cover of the March 29, 2007 issue of the Journal of Physical Chem-istry C.

Tom and graduate student Carlos Hernandez made the world’s fi rst ‘col-loidal alphabet soup’, composed of microscale versions of all 26 letters of the English alphabet in 1/100th point font. (This article uses 9-point font.)

The random thermal ‘Brownian’ mo-tion of the letters is signifi cant, so they rotationally and translationally diffuse, as is easily seen using optical micros-copy. By incorporating fluorescent dyes into these polymer letters, the Mason group is creating new types of biomarkers that can be detected by their shape and not just their fl uorescence

signatures. This work has been recog-nized twice by Nature, as a research highlight and as a technology feature [“Down to the Letter”, Nature 446 940 (2007)]. The striking image of colloidal alphabet soup will also appear in the catalogue of “Design and the Elastic Mind” exhibit at the Museum of Modern Art in New York City in 2008. In addi-tion to developing and optimizing new methods of mass-producing particles, Tom’s group is currently exploring ways of manipulating and assembling the particles in a controlled manner to build tiny structures.

The Mason group is also interested in nanoemulsions, aqueous dispersions of nanoscale oil droplets, stabilized against coalescence by a surfactant. Nanoemulsions are similar to ordinary microscale emulsions in composition, but their synthesis requires extreme conditions (high mechanical flow or shear) to effectively rupture larger drop-lets into nanoscale emulsion size. To achieve such high fl ow rates, Tom relies

on high-pressure microfl uidic technol-ogy. White, liquid-like microscale emul-sions fed into the microfl uidic device emerge as a transparent, solid-like cream. Graduate student Jim Wilk-ing has shown that nanoemulsions can have a very high elasticity even at very small droplet volume fractions,

implying most of the emulsion is water, not oil. Nanoemulsion elasticity is a product of the nanoscale droplet size and is not found in microscale and larger emulsions. This research about nanoscale mayonnaise, also known as ‘nano-naise’, was recently published [“Irreversible Shear-Induced Elastic Vit-rifi cation of Nanoemulsions by Extreme Droplet Rupturing,” J.N. Wilking and
