LBL Currents -- April 1, 1994

Chemists develop environmentally friendly catalysis technique

By Lynn Yarris,

Red light could turn chemistry "green!" Researchers in LBL's Structural Biology Division (SBD), led by chemist Heinz Frei, have developed a technique in which red light is used to convert abundant hydrocarbons into valuable chemical compounds at no cost to the environment.

A central theme of current catalysis research is the redesigning of the industrial processes used to manufacture plastics and other synthetic materials.

Frei explains, "Many current synthesizing processes in industry create problems for the environment. They also waste energy. Industry needs new processes that are product specific, environmentally benign, and energy efficient."

Most synthetic materials are made through the oxidation of small hydrocarbons, one of Nature's most plentiful raw materials. For the past several years, Frei has been exploring the use of red and near-infrared radiation to initiate hydrocarbon oxidation in a tightly controlled fashion. Because red and near-infrared photons are the least expensive to artificially produce, this photochemical technique is economically competitive with other catalytic methods.

In earlier work, Frei and coworkers achieved oxidation reactions in a "cryogenic matrix environment," where potentially reactive molecules were immobilized in a frozen gas and irradiated with red and near-infrared photons. These photons are substantially lower in energy than the blue or ultraviolet light most often used in photochemistry.

"The use of low energy photons gave us access to low energy reaction pathways," Frei says. "This gave us product specificity because we were below the dissociation energies of the reaction partners. Excitation above dissociation energies often leads to unwanted byproducts."

Now, working with Fritz Blatter and Hai Sun, Frei has developed a new technique for selective hydrocarbon oxidation that not only permits the use of red and near-infrared photons, but also enables photochemical reactions to take place at room temperature. What makes this possible is the immobilization of reactants not in a cryogenic matrix, but in molecular-sized cages of inert solid materials called zeolites.

Zeolites are alumino silicates used widely in the petrochemical industry as catalysts. They feature unique pore structures inside which smaller molecules can be imprisoned. Using a synthetic version of a natural zeolite called faujasite, Frei and his colleagues successfully held and photo-oxidized small alkene molecules into industrially important chemical building blocks and intermediaries such as hydroperoxides, carbonyls, and epoxides. This was accomplished without the customary release of carbon dioxide, the chief contributor to global warming and the greenhouse effect.

To photo-oxidize their alkene molecules, Frei and Blatter loaded them as a gas into zeolite pellets and added oxygen. Reactant molecules paired with one another and were held together by the zeolite cages in close contact so that irradiation with red light triggered oxidation.

Says Frei, "Zeolites offer an ideal environment for the formation of new complexes at high concentrations. Excitation of these complexes with light allows us to access reaction surfaces and, in some cases, products that are not attainable through conventional thermal activation."

Another advantage in using zeolties, Frei points out, is that their inherently large electrostatic fields act to stabilize the excited charge-transfer energy states of hydrocarbon-oxygen complexes. This allows zeolite photochemistry to be performed with light from a conventional tungsten lamp rather than a laser.

Since practically all of the polymers from which come today's synthetic materials are manufactured from chemical building blocks that are themselves produced by oxidation of hydrocarbons, Frei's red-light photochemistry research has far-reaching industrial potential. He and his colleagues are now studying the application of their technique to organic compounds derived from hydrocarbons.

Director Shank gives annual report to UC Regents

By Lynn Yarris,

"The view of science in the country is undergoing a dramatic change that affects both the university campuses and the national laboratories," LBL director Charles V. Shank told the UC Regents in his annual report to their Committee on the Oversight of the DOE Laboratories. "Everyone thinks that the change affects only the weapons labs but non-weapons laboratories are also being influenced. We're being asked to solve problems that respond to national needs and to explain how we benefit the nation."

In his March 18 presentation, Shank explained how the DOE task force formed by Energy Secretary Hazel O'Leary and chaired by Robert Galvin of the Motorola Corporation (see Currents, March 25) is assessing the performance of all the national laboratories in terms of the benefits they deliver to the nation.

"If we at the national laboratories are going to prosper and be supported in the future the way we have been supported in the past, we're going to have to reach out and explain what we do and how our (research) progress relates to solving problems that people really care about," Shank said.

As examples of fundamental research at LBL that are now being applied to areas of national concern, Shank cited work in the Energy and Environment Division begun by high-energy physicists that has paved the way for superwindows, advanced lighting systems, and computer-based energy-efficient building designs, plus the invention of a biologically sensitive thin film in the Materials Sciences Division that can be used to diagnose for flu virus. Shank also discussed LBL's forefront participation in the creation of a national electronic information highway, and how the American textile industry has turned to LBL and other national laboratories for the technology that can help stem the loss of hundreds of thousands of jobs to foreign competitors.

Through a computerized system of demand-activated marketing, Shank said, "We can enable domestic manufacturers to regulate their inventories with an efficiency that just can't be done today."

In speaking about the future of LBL, Shank stressed that the Galvin task force and other upcoming reviews of the national laboratory system makes it imperative that "we identify problems of national importance where our research can make a difference."

As to the solution of these problems, Shank said LBL will be most effective by building partnerships with the University campuses and with private industry.

"We're going to have to please those who represent the American people so that, in the future, they will fund us in a healthy manner and give us an opportunity to deliver the benefits that we are capable of providing."

Science and Technology in a Competitive World

Ralph Gomory, president of the Alfred P. Sloan Foundation, will be the next guest speaker in the LBL lecture series Science and Technology in a Competitive World. He will speak on "Uncertainty and the Federal Role in Science and Technology" at noon on Monday, April 4, in the Bldg. 50 auditorium. All employees are invited to attend.

LBL graduates its first class in management-training program

By Mike Wooldridge,

LBL Director Charles Shank hailed it as a program that will have a lasting impact on the Laboratory. Participating LBL managers--many of them admittedly skeptical when they began the program--say it has already improved the way they manage.

With fanfare and personal testimony, the FrontLine Leadership Training Program graduated its first "class" on March 21 in the Bldg. 66 Auditorium. More than 120 directors, department heads, managers, and supervisors from the Administration and Operations divisions celebrated the completion of a six-month (July--December) series of half-day-long classes on communication and problem solving. By the end of summer, approximately 300 lab employees will have undergone similar training through the program, which is administered by Zenger Miller Inc. of San Jose.

The program consists of modules that focus on issues critical to successful leadership and successful management, such as recognizing positive results and giving constructive feedback. The classes help supervisors in conflict resolution, for example, by focusing on the situation, issue, or behavior, rather than the individuals involved in the situation.

"The concepts in the program are not difficult, or even unique," said Klaus Berkner, Associate Lab Director for Operations. "But they are concepts managers need to practice to improve their skills."

Rod Fleischman, Associate Lab Director of Administration, and Berkner brought the program to LBL with hopes of revitalizing management in their divisions. While the first phase involved the training of their own managers, including division administrators and some Director's Office supervisors, it is expected that future phases will bring in supervisors from across the Lab.

In addition to improving an individual's supervisory skills, the program has helped LBL supervisors communicate with one another, and recognize that many of the problems they face are shared by others. "The program has given us a common language that we can use when discussing issues," said Anil More, of the Environment, Health and Safety Division. More was one of several participants who spoke about the program during the graduation ceremony. He was joined by Leslie Cobb, Jan Turrini, Bob Fink, and Fred Lothrop.

The principles taught in the course are summarized in a small notebook that participants keep with them. Nicknamed the "blue fuzzy," the booklet has turned into something of a unifying tool itself, giving program graduates a common ground on which they can work out problems in management meetings.

"When people walk into a meeting with the blue book in their hand, it gets everyone's attention," said Fleischman. "It's been fun trying to apply the principles to real situations, and to try and make sure our policies and actions are consistent with them."

Several participants, including More and Lothrop, head of the Reception Center, have formed groups outside the program in which fellow graduates can discuss how they have progressed with what they learned in the program.

The next two phases of the FrontLine Leadership program are already under way with two more groups of LBL managers. New modules emphasizing quality and teamwork will be offered in April to graduates of the first phase as part of the ongoing training program.

The first group of participants in the FrontLine Leadership Training Program celebrated the completion of the program with a graduation ceremony in the Bldg. 66 auditorium.

New LBL documentary features search for heavy elements

By Lynn Yarris,

"The Search for Heavy Elements," a half-hour video that documents the expansion of the periodic table through the creation at LBL of elements heavier than uranium, will premiere at noon on Tuesday, April 5, in the Bldg. 50 auditorium. All employees are invited to attend. A second showing is scheduled for Thursday, April 21, at the same time and location.

Produced by Diane LaMacchia of the Public Information Department, "The Search for Heavy Elements" tells its story through a mix of rarely-seen archival footage, historical photos, interviews with scientists who made the history--such as Glenn Seaborg and Albert Ghiorso--and computer animation created by Flavio Robles Jr. of the Technical Information Department in consultation with Crystal Stevenson. The video has

The presentation is also timely as it culminates with the discovery of element 106 and the naming of this newest member of the periodic table "seaborgium"--the first time an element has ever been named for a living person.

Historical film footage was courtesty of Vicky Chen and Lori Hefner of LBL Archives. Copies of the new video will be available for purchase. For information, call Diane LaMacchia at X4015.

Proposals sought for FY 1995 Lab-directed R&D Program

LBL Director Charles Shank has issued the call for proposals for the FY1995 Laboratory Directed Research and Development Program (LDRD). This program provides support for projects in forefront areas of science and technology that can enrich Laboratory R&D capabilities and achievements.

For FY 1995, emphasis will be given to supporting new R&D initiatives that connect with Laboratory core competencies identified in LBL's institutional and strategic plans. The Director encourages multi-investigator, multi-divisional initiatives.

Proposal forms have been distributed to division directors and administrators. Proposals are due to division directors by Friday, April 29. After conducting an internal review and evaluation, division directors should forward the proposals to the Director's Office by Friday, May 13. Incomplete proposals will be returned to division offices, which will have an opportunity to revise and resubmit them by May 27.

Division directors will present the proposals to a review committee composed of the director, deputy director, associate lab directors, and other division directors from the same program area. The director will make the final decisions.

Support for the program comes from Laboratory overhead; its budget allocations are not subject to scientific burden. Approximately $5 million in operating expenses is planned for FY94. The level of capital equipment funding, which is a separate allocation, is planned to be about $500K. If capital equipment is requested, it must be an integral part of the submitted proposals, as indicated in the guidance. Funded projects will be announced in August.

The call for proposals and forms are also available on Appleshare, DIR zone, OPD Server, LDRD file.

Mosaic links LBL to the World

Mosaic, a new system for discovering, retrieving, and displaying information on the Internet, has arrived at LBL.

Mosaic is public domain (free) software that allows individual computers to access information in the World Wide Web, a network that links databases at LBL and around the world. Versions of Mosaic are available for Macs, PCs, Sun, Silicon Graphics, and VAX workstations.

Taking advantage of Mosaic, groups around the Laboratory are setting up computer-based libraries of text, images, and scientific data. This information can be browsed from any network-linked computer or workstation at LBL or from computers anywhere on the Internet.

Current Lab users of Mosaic include the Human Genome Center, the Engineering Division, the Imaging and Distributed Computing Group, and the Advanced Light Source.

A partial list of general-purpose on-line information about LBL includes the 1993 catalog of LBL research abstracts, LBL Currents, LBL Computing Newsletter, an archive of science articles from Currents and the LBL Research Review, multiple library catalog services, phone numbers and e-mail addresses for LBL employees, and the Current Jobs Offerings.

To help you navigate the World Wide Web, the LBL Mosaic server includes hypertext links to scores of other destinations selected because of their likely interest to the LBL community. These outside resources include other national laboratories, the White House, the Library of Congress, SLAC, CERN, major universities around the world, museums, federal archives, systems with maps, audio files, and even film clips.

Because Mosaic is new at LBL, the information it provides is constantly being updated and expanded. All information is searchable and easily accessed.

Setting up LBL's World-Wide Web databases has been a collaborative project headed by Martin Gelbaum and Case Larsen of ICSD. Others involved in the project include Jeff Kahn of the Public Information Department; Gabby Obegi, Jeff Shaw, and Donn Davy of the Engineering Division; and Arun Aggarwal of ICSD.

The Lab has scheduled an on-line presentation of Mosaic at noon on Monday, April 11, in the Bldg. 50 auditorium. Bill Johnston, who heads the Information and Computing Science Division's Imaging Technologies Group, will demonstrate how to use Mosaic.

How to get started

To install and run Mosaic from a Macintosh, get "NCSA Mosaic" from the WKSG server in the wksg zone, via Appleshare. Copy the entire NCSA Mosaic folder from the Information Retrieval folder in the Communication folder in the Public Access volume. Then, read and follow the directions in the "README-LBL" file in that folder. For assistance, call the Workstation Group at X6900.

For PC users, first you must have Windows as well as LAN Workplace for DOS installed on your PC. To install Mosaic, get the MOSAIC distribution disk from the Workstation Group and run "INSTALL." To start Mosaic, double-click on the Mosaic icon in Windows (often found in the Applications Group). PC users who need help should call the Workstation Group at X6858.

Mosaic has been installed on the Sun, SGI, VAX, and Alpha computers managed by LBL's Unix and VMS groups. Mosaic requires that you run X11 or OpenWindows on UNIX, or DECWindows/Motif on VMS. If you have a character-based system (such as VT100), you will not be able to run Mosaic. However, much of the information available on the World Wide can be viewed through lynx.

Women in Science & Engineering Seminar

Jane Long, head of the Earth Sciences Division's Energy Resource Development Department, will give the next talk in the Women in Science and Engineering seminar series, scheduled for 12:10 p.m. on Tuesday, April 5, in Bldg. 70A-3377 (please note change of day). She will speak on "Fluid Flow Through Fractures in Rocks," which she explains as follows: Fluids such as water or oil flow through fractures in rock. Although rocks underground are ubiquitously fractured, only a few fractures may actually conduct fluids. The genesis of the fractures may provide some clue as to which are important. Geophysical techniques help to see these fractures and design appropriate hydraulic testing programs. These techniques taken together help to predict such varied problems as how nuclear waste repositories will perform, how more oil can best be produced from resevoirs, or how underground tunnels will remain dry.

Refreshments will be served at noon. All employees are invited to attend.
