Tiny metal libraries a big tool for materials scientists

By Mike Wooldridge, [email protected]
The pace at which researchers can create and test new advanced materials should be quickened from the current rate of about one compound a day to as many as 10,000 with a technique developed by scientists in the Materials Sciences Division.

Working at LBNL's Molecular Design Institute, the researchers have found a way to deposit thousands of distinct combinations of metal-oxide molecules onto an area the size of a checkerboard square, thereby creating the first "combinatorial library" of advanced materials. The technique uses "masks" to stencil thin layers of metal-oxide ingredients onto different columns and rows of an inch-square grid. It has already been used to create libraries of high-temperature superconductors.

The research was described in a cover story in the June 23 issue of the journal Science by physicist Xiao-Dong Xiang and chemist Peter Schultz, who is also a professor of chemistry with UC Berkeley. The Lab recently licensed the method to Symyx Technologies Inc. of Palo Alto (see article on pg. 3).

The combinatorial strategy is a departure from so-called rational design, where researchers try to predict beforehand which molecular structures will yield desired properties. The new strategy relies more on sheer numbers--making a myriad of theoretical candidates and sorting through the bunch to find a solution.

The combinatorial approach has been used successfully by researchers in the life sciences to screen for potential drugs. This is the first time scientists have applied it to solid-state materials.

A high-volume strategy makes sense considering the wide range of possibilities scientists are faced with when concocting new materials. Just the five-element combinations available on the periodic chart represent millions of potential compounds. Metals can be combined at different ratios; they also form different molecular structures depending on the temperatures or pressures at which they are treated. The result is an enormous advanced materials "universe," much of which scientists still know very little about.

"In the vast majority of cases, the important discoveries in materials science are serendipitous." Xiang says. "It is very difficult to predict how these structures will behave before you make them." Until now, scientists have had to resort to making new materials by trial and error, one at a time.

The combinatorial approach has long been known as a way in which the human body solves problems. The immune system, for instance, has a library of about one trillion differently shaped antibodies, each made up of different combinations of protein chains. When faced with an invading agent, such as a virus, the immune system selects the antibodies from the trillion that happen to bind to the virus. Their numbers are multiplied to fight the infection.

The key point is that there is no rational design of antibodies to fit a particular virus. The strategy is to create a wide variety of combinations that can be selected from after the fact.

Previously, Schultz has borrowed the immune system's combinatorial strategy to invent "catalytic" antibodies--antibodies that, because of their shape, promote certain chemical reactions. Similarly, biotech researchers have used a combinatorial approach to select potentially useful drugs from large libraries of randomly generated molecules.

To apply the same philosophy to materials design, the researchers turned to thin-film technology, a method in which very small amounts of a complex metal material can be manufactured quickly. Metal components are laid down atop one another, each layer 10 to 100 angstroms in thickness. The layers are heated to mix the metal elements and create a stable, composite compound.

The researchers create arrangements of different metal combinations by depositing the thin films through masks. A so-called primary mask, with square openings like those on a screen door, is used to lay the metals down as a grid of separate squares. A secondary mask, laid atop the primary mask, serves to block out specific rows or columns of the grid. By sending the metals through different secondary masks, each can be deposited on particular sections of the grid.

To test the technique, the researchers created a small, 16-member library of copper-oxide high-temperature superconductors. Then they laid down a base layer of copper through the primary mask, then deposited layers of four other metals--oxides of bismuth, calcium, lead, and strontium--through different secondary masks. Because of the sequence of masks, each site on the grid received a different combination of metal oxides. Every possible combination was represented once.

After heat treatment, the researchers tested the electrical characteristics of the materials in their library. Results showed the copper-oxide thin-films had the same resistive characteristics as superconductors created by large-scale means. The researchers went on to successfully make denser, 128-site superconductor libraries with combinations of seven metals.

Tests with decreasing mask sizes showed that the method could produce working superconductor films as small as 200 microns by 200 microns. At scales below 200 microns, metal-oxide molecules in the thin layers begin to evaporate.

"With 200-micron sites, we can realistically deposit 10,000 materials in a square inch area," Schultz says.

Over the next four years, approximately 1,500 Bevatron shielding blocks will be trucked to the freight yards in Richmond, then transported by rail to New York for re-use with the Relativistic Heavy-Ion Collider at Brookhaven. The recycling effort will save taxpayers millions of dollars and spare needless use of precious waste burial space. Photo by Steve Adams

Chemists get hint of things to come with successful beamline test

By Lynn Yarris, [email protected]
Users of the chemical dynamics beamline of the Advanced Light Source (Beamline 9.0.2) got a taste of things to come during a recent experiment in which the ALS electron beam was accelerated to little more than half its full energy (1.0 GeV rather than 1.9 GeV). The low energy photons (8-12 eV) that resulted gave the users a preview of the selective chemistry they will be able to perform this fall when the beamline's current 8.0-centimeter-period undulator (U8) is replaced with a new 10.0-centimeter-period undulator (U10).

"The use of low energy photons enabled us to take a blowtorch rather than a sledgehammer approach to photochemistry," says Arthur Suits, a chemist in the Chemical Sciences Division and member of the beamline research team that includes Nobel Laureate Yuan T. Lee. "Instead of bombarding molecules with high energy electrons to create fragments for analysis, we can use soft photons to selectively ionize the products we want to study."

The 8-12 eV photons that were produced especially for this proof-of-principle experiment are at the valence energy of most radicals--atoms and molecules that possess one unpaired electron and play a vital role in combustion and atmospheric chemistry. (The valence energy is where the chemical activity of an atom or molecule takes place.) By tuning their photons to just above this valence threshold, the beamline researcher team was able to separate hydrocarbon molecules from alkylamine compounds without fragmenting larger molecules. This gave them a "near-zero background" detection capability.

Despite the abundance and potential importance of alkylamine compounds, scientists have until now lacked the tools to selectively study the dynamics of their photochemistry. When the U8 undulator is replaced with the U10 undulator --scheduled for September--researchers on the chemical dynamics beamline will have regular access to photons at energies as low as 5 eV. These photons will be delivered in an intense beam (1016 photons per second flux) of bright white light. A rare-gas filter will give the white undulator light unprecedented spectral purity.

"This will be a novel application of synchrotron radiation made possible because of the brightness of the light (a thousand times brighter than conventional synchtroton light beams)," says Suits. "Rather than serving just as a probe of stable systems, the radiation can be used for selective ionization and product detection in primary photodissociation reactions. From this, we expect to get quite a bit more information on the detailed dynamics of these processes and study systems that were previously inaccessible."

Currently, Suits and the other members of the beamline research team are using one endstation. A second branch and endstation for the chemical dynamics beamline, designed by Cheuk Ng of the Ames Laboratory at Iowa State University, is now being installed and should be complete in time for the new U10 undulator. This second branch will feature a 6.65-meter monochromator that will provide users with the highest resolution of any scanning monochromator in the world at its spectral region. The branchline will also be equipped with a state-of-the-art electron spectrometer and several lasers, including a custom-made high-resolution infrared laser.

In addition to Suits, who is the technical director for the chemical dynamics beamline research team, others working on this project include postdoc Xueming Yang, who designed the first endstation and performed the alkylamine experiment, and David Blank, a graduate student in Lee's research group. Phil Heimann of the ALS staff is the coordinator for this beamline and is overseeing the installation of its new components.

1995 Summer lecture series

Earth Sciences Division Director Sally Benson will give the fifth and final talk in the Lab's 1995 Summer Lecture Series. She will speak on "Groundwater Cleanup: Cost Effective Remedies," at noon on Wednesday, July 26, in the Bldg. 50 Auditorium.

Regulatory reform legislation that would require federal agencies to perform risk assessments and cost-benefit analyses is big news these days. What role can a multiprogram laboratory such as LBNL play if these bills become law?

Benson will demonstrate a PC-based software system developed at the Lab that integrates, analyzes, and presents environmental information to help managers, engineers, scientists, regulators and the public select the most cost-effective environmental remediation strategies.

Since 1977 Benson has performed research on energy and environmental issues, including geothermal energy sources, natural gas storage, and agricultural pollution in California's Central Valley and the Carson Desert in Nevada. More recently, she has focused on environmental problems associated with the DOE weapons production complex.

White to resign as DOE Deputy:

Deputy Secretary of Energy William White has announced he will resign his position on August 11 and return to Houston, where he had been a managing partner in the Susman Godfrey law firm and a prominent Democratic fund-raiser. Under-Secretary Charles Curtis will succeed White. There is no word yet on who will replace Curtis. White told reporters a significant factor in his decision to leave the department is his confidence that DOE has "turned the corner" in defending itself against those in Congress who would abolish it.

Science speaks up:

In the July 7 issue of Science magazine, an editorial by Phil Abelson noted that with an annual trade deficit approaching $200 billion, the United States has become the world's largest debtor nation. An international conference in Washington, D.C., sponsored by the National Academy of Sciences, concluded that a principal reason for this deficit has been the failure of many politicians to recognize the importance of partnerships between government and industry in the development of new technologies. Abelson wrote, "Congress rails against support of industrial technology at a time when many nations eagerly enhance it. Moreover, in a world in which U.S. industry and the defense establishment will be dependent on well-trained scientists and engineers, current proposals to decrease support for both basic and applied research are a recipe for future national mediocrity."

Department of Science redux:

Republicans, led by Rep. Robert Walker (R-Penn.), are talking about creating a Department of Science, in part because they need to find a home for research programs that would be orphaned if they succeed in abolishing DOE. Former Deputy DOE Secretary Henson Moore, who served under Energy Secretary James Watkins in the Bush Administration, has heard all the arguments for a Department of Science before. He testified before the House Science Committee that the idea was first proposed by Republicans in 1989 who wanted to expand DOE. Moore said Watkins considered the idea "empire-building" and that it was left for a second Bush presidential term. Allan Bromley, Bush's science adviser, did not like the idea at all. "Nobody thought it was a good idea," he says. "It was just an attempt by DOE to expand its turf."

SSC fire sale:

This fall a huge auction will be held in Waxahatchee, Texas. Up for bid will be approximately 6,500 hectares of land, a $65 million linear accelerator, and 14,000 square meters of office and warehouse space. The state of Texas, owner of this property, is trying to recoup some of the $500 million it spent for construction of the now defunct Superconducting Super Collider. Earlier plans to put the SSC site to use as a cancer treatment facility or supercomputing center fell through when state officials balked at spending more money. Instead they ordered the auction and are trying to buy back the remaining $250 million in state bonds issued to finance the project. DOE has already written off its $2 billion investment and has shipped the most valuable scientific equipment to other national labs.

Was Sir Isaac Newton correct?

The National Association of Scholars, a group of traditionally minded academics, has been concerned that "political correctness" in academia is spreading a stain of anti-intellectualism and hostility to science. In the inaugural issue of its new electronic newsletter, the organization cites an opinion expressed by feminist philosopher Sandra Harding that Newton's Principia Mathematica reflects patriarchal, exploitative Western thinking and therefore might as well be called "Newton's Rape Manual."

Tours a hit with visitors

The Laboratory played host to two large groups of visitors on July 13 with the visit of 38 physics teachers from Denmark and 100 members of the Commonwealth Club of San Francisco.

The teachers, who came from the Danish Gymnasium (equivalent to the last year of high school and first year of college in the U.S.) came to LBNL as part of a study tour of Bay Area laboratories and educational institutions. Their tour included trips to Stanford, Livermore, the Exploratorium, and several private research labs.

According to tour leader Jannik Johansen, the highlight of the trip was their visit to LBNL, where they toured the Advanced Light Source, Bevatron, and National Center for Electron Microscopy. In addition, physicist Carl Pennypacker introduced Hands-On Universe, and nuclear scientist Rick Norman delivered a presentation on the Sudbury Neutrino Observatory.

Later in the evening, 100 Commonwealth Club members were welcomed with a reception in the Bldg. 50 Auditorium foyer, where they were greeted by senior Lab management, ALS and Nuclear Science Division members, and staff from Industry and Government Partnerships.

Following the reception, Director Charles Shank presented an overview of LBNL research, and answered a variety of questions about science programs, the outlook for DOE, and the problems of nuclear waste disposal. His presentation was followed by tours of the ALS and 88-Inch Cyclotron.

Both tours were organized by IGP's Community Relations Office.

Lab swaps science for stock in start-up company

The recent licensing of a new "combinatorial library" technology--developed at LBNL's Materials Design Institute--to Symyx Technologies Inc. (see related article) has ushered in a new way for the Lab to do business.

Symyx paid for much of the license fee with common stock, rather than cash, giving the Lab part ownership of the Palo Alto start-up firm.

According to Technology Transfer's Viviana Wolinsky, this is the first time a UC-managed lab has arranged a license-for-stock agreement. It is the twelfth such deal that has been arranged in the UC system.

DOE's mission obligates LBNL and other national labs to help small businesses--companies with fewer than 500 employees. However, small start-up firms are often the least able to generate cash to pay for licenses. Obtaining a license with stock can be an attractive alternative for small companies.

Symyx plans to use the new technology to develop superconductors, phosphors for flat-panel displays, dielectric materials, zeolites, and magnetic materials. The company is backed by biotech pioneer Alex Zaffaroni of Affymax Inc., which has used combinatorial strategies to design drugs. The agreement is expected to create 80 jobs at Symyx over the next 4 years.

Lab Director Charles Shank said he is pleased with the Symyx agreement, and believes this way of partnering may play a significant role in future licensing. As for its effect on tech transfer at LBNL, Wolinsky said "it's one more arrow in our quiver, another way the Lab can get its science out into private industry." --MW

Fire fighters strike bronze

CAPTION -- LBNL fire fighters Harold Blair and Gary Dunbar, and Oakland Airport fire fighter Ike Saenz wear the bronze medals they won at the 1995 California Fire Fighter Olympics last month. The three were part of the third-place bowling team, along with Sam Hoffman of the Berkeley Fire Department. This is the sixth such medal for Blair and the first for Dunbar.
