Electron microscope gives visiting chemist unique look at airborne particles

By Diane LaMacchia, DMLaMacchia@LBL.gov

Analytical chemist Lynn McInnes visited LBL recently from the University of Colorado to study the chemical composition of sea salt and sulfate aerosols.

To examine samples of the airborne particles, she used the Analytical Electron Microscope (AEM) at LBL's National Center for Electron Microscopy. A national user facility that is open to all qualified researchers, NCEM offers unique capabilities not available elsewhere. "At the facilities here you can actually do chemical analysis on an individual aerosol particle," McInnes says.

She and collaborators from the National Oceanographic and Atmospheric Administration (NOAA), the University of Seattle, and the University of Colorado's Cooperative Institute for Research in Environmental Sciences are analyzing two types of particulate matter: remote background aerosols, which contain natural compounds such as sea salt and sulfuric acid, and aerosols that contain anthropogenic pollutants such as soot.

In this day and age, it is not easy to find the former.

"There are only a few places left in the world where you can get them," McInnes says. "The South Pacific is one such place. In the Atlantic, you are more likely to pick up pollutants coming from the American and European continents."

The aerosol samples she brought to LBL were collected over the Pacific Ocean on a 1993 NOAA cruise of the Surveyor from Punta Arenas, Chile, to Seattle, Wash. She also brought samples from land-based monitoring stations at Cheeka Peak, Wash., and Niwot Ridge, Colo. Samples from Cheeka Peak, a coastal station, were collected when the wind was coming off the water, mainly bringing a marine source of particles to the land. Samples from the inland station, Niwot Ridge (elev. 9,500 ft.), contained some pollution from Denver.

Aerosol particles are known to scatter incoming solar radiation and serve as nuclei for cloud formation. Studies of remote aerosols help establish a background set of measurements with which to compare polluted situations in an effort to learn how pollutants affect the amount of sunlight that gets to the ground. Like previous studies on the effects of carbon dioxide in the atmosphere, these studies will add to our knowledge of how human behavior may precipitate climactic change.

McInnes is particularly interested in sulfate particles--their concentration, size, longevity, and physical properties. Sulfate is one of the major pollutants contributed to the atmosphere by human activities, but there are also natural sources of sulfate. The ocean releases gaseous dimethyl-sulfide (DMS) as a by-product of phytoplankton, the plant material of the ocean. Once in the atmosphere, DMS can change form to become sulfate particles. The gases can also form sulfate on sea salt particles. McInnes is studying the processes by which the pollutant material attaches to the natural aerosol and how the combined aerosols result in changes to cloud coverage.

Typically in the past, McInnes says, people used bulk techniques in measuring aerosol properties and chemical composition. In that situation, the major components by mass--often the larger particles--dominate the findings. But McInnes came to LBL to study the small particles that dominate by number.

She says the AEM was a good tool for her study, because it can isolate one particle and look at its spectra to provide elemental information. Its special detectors analyze which elements the particle has reacted with, from carbon on up. Because the particles are so small, electrons pass right through them, generating images on a screen below.

"This is a really good facility," McInnes says, "because not only does it have these microscopes, but it has dark room facilities to print up the images, computer facilities to do automated image analysis, and personnel who are qualified in each of those areas. They make sure you've collected the information you want."

By studying the size distribution and chemistry of the aerosol samples, McInnes hopes to understand something about their physical properties and behavior. For example, will particles grow into cloud droplets when they are exposed to water vapor? How does gaseous sulfur become sulfate, and how much sulfate is out there now? How long will the particles stay in the atmosphere?

At bottom lies a larger question, McInnes says. "Are we putting all of this material into the atmosphere to stay there forever, or will it get removed?" The answer could be an important one for understanding climate change.


NCEM Fellowship program unites young scientists, state-of-the-art equipment

Analytical chemist Lynn McInnes and other young investigators are able to use the unique facilities at LBL's National Center for Electron Microscopy thanks to a special fellowship program.

"The NCEM Visiting Scientist Program was designed to help those who couldn't otherwise have access to such facilities," says NCEM Acting Head Michael O'Keefe. (NCEM Head Uli Dahmen is on sabbatical). "We invite applications from young scientists who are just starting out in their field, or are starting up a lab and don't have their equipment yet, but want to get started."

The fellowships are up to three month's duration and carry a stipend to defray travel and living expenses.

McInnes, a research assistant from the University of Washington, was one of three participants in last year's program. Another, an assistant professor from NC State University, worked on polymers during his visit, while an assistant professor from Rice University studied structural transitions, plasticity, and controlled fracture initiation in a variety of ceramics. There are nine applicants this year, O'Keefe says.

The finalists are selected based on recommendations of the NCEM Steering Committee, a group composed of researchers from LBL, other national labs, universities, and industry that meets annually.

LBL PEOPLE:

Kwang-Je Kim, a senior physicist in the Accelerator and Fusion Research Division, and deputy head of the Center for Beam Physics, has been elected a Fellow of the American Physical Society. The citation, which acknowledges his "fundamental contributions to the theory of synchrotron radiation and free electron laser sources, especially concerning brightness, polarization, self-amplified spontaneous emission and laser-driven rf electron gun," will be awarded at the 1995 Particle Accelerator Conference in Dallas, Texas.

PEOPLE IN THE NEWS:

Dick Fish, a chemist in the Energy and Environment Division, was featured in the April 17 issue of Chemical and Engineering News for reporting the first example of the recognition of aromatic amino acid guest molecules by bio-organometallic hosts in aqueous media. Molecular recognition is a critical element in catalysis, but studies of this phenomenon in the past have involved only organic hosts. Few studies were done with inorganic or organometallic hosts because such complexes tend to be too unstable. Fish and his group were able to synthesize stable bio-organometallic complexes that they then studied through the use of proton NMR spectroscopy.

WHAT DOES THE MILKY WAY LOOK LIKE?:

Is the familiar image of the Milky Way--a pinwheel disk with an egg-yolk bulge in the middle--wrong? A coalition of American, British, and Australian scientists that included researchers from LBL's Center for Particle Astrophysics has reported in the journal Physical Review Letters that the Milky Way may be what is called a "barred-spiral"--a galaxy with a huge bar of stars extending across its entire plane and a curved arm at each end. This new depiction of our galaxy arose from the coalition's determination that the halo of dark matter believed to surround the Milky Way contains far fewer Machos (Massive Compact Halo Objects) than was thought, while the galaxy's central region contains far more than was expected. The scientists have been using the phenomenon called "gravity lensing" to look for Machos in the dark halo of the Milky Way. Machos are thought to range from the size of the earth to half the size of the sun and could include planets, black holes, and brown dwarfs, stars that were not quite massive enough to initiate fusion.

COLD WAR CLEANUP COSTS:

A new report from DOE's Office of Energy Management (OEM) estimates that the cost of cleaning up the nuclear weapons facilities, based on a 75-year timetable, will be about $230 billion. This is about what the nuclear weapons program cost this country's taxpayers during the 50 years of the Cold War. The General Accounting Office had pegged the cleanup price at around one trillion dollars. OEM head Thomas Grumbly says that the DOE estimate is based on "information taken not from Washington bureaucrats as in the past, but from people who know the sites intimately." The estimate is also based, he said, "on common-sense estimates of available technologies, not on mere wish lists." The new report is entitled: "Estimating the Cold War Mortgage." It can be obtained by calling 1-800-736-3282.

Earth Month wraps up

The Laboratory celebrated Earth Month 1995 with plenty of earth-minded activities throughout the month of April. LBL's Green Team, Community Relations and Outreach Network helped organize two trash tours, a lecture on Bats, an Eco-Fair, and other events.

CAPTIONS -- Deputy Lab Director Klaus Berkner said he got his fill digging vegetable gardens as a boy and now does only ornamental gardening. However, he got into the spirit last week by helping to inaugurate the Lab's new Community Garden, located between Bldg.s 2 and 29. Plans call for the garden, which was launched by LBL's Green Team, to host a variety of vegetables and flowers--employees are invited to submit suggestions. All interested employees are invited to a garden meeting at noon on Monday, May 1, in Bldg. 51-205.

Hundreds of employees stopped by the Eco Fair last week to learn about recycling, composting, energy efficiency and more from the many groups from LBL and beyond that had booths set up on the cafeteria lawn.

Fifteen community-spirited employees gave up their lunch hour one day this month to see what they could drag out of the bushes around the Bldg. 65 bus stop area. In 25 minutes they collected 200 pounds of trash, including an old bicycle, a spare tire, several parking barricades, lead bricks, and the usual assortment of discarded items. Everyone who participated in the litter pickup, which was sponsored by the Green Team, received an LBL mug for their efforts.

Campus comes alive for Cal Day

UC Berkeley will open its doors from 10 a.m. to 4 p.m. on Saturday, April 29, for Cal Day--a free, campus-wide open house. More than 70 departments and museums will have faculty, students and staff on hand to showcase their courses, programs and expertise.

Some of the highlights:

Cal Day will be kicked off at 10 a.m. at the Campanile by Chancellor Chang-Lin Tien and Berkeley Mayor Shirley Dean. Shuttle buses and motorized cable cars will ferry visitors between events. Programs will be available at the six campus entrances.


Bike to Work Day Transportation Fair

By Brennan Kreller, BPKreller@LBL.gov

As part of its recognition of National Bike Month this May, the Laboratory has named Thursday, May 4, as Bike to Work Day. All employees are urged to give up their cars for a day and ride a bike to work (or use other alternatives to driving).

The Laboratory will also hold its first annual Transportation Fair on May 4, from 11 a.m. to 2 p.m. in the cafeteria parking lot.

Participants include AC Transit, Commute Mobil, BART, East Bay Bicycle Coalition, LBL Bicycle Coalition, Rides, VPSI Vanpool and Leasing, and others. All employees are invited to attend. Refreshments will be served, and there will be prizes for employees who bike to work.

The fair is part of a new strategy of the Lab's Employee Transportation Coordination Office to encourage reduction of vehicular traffic and emissions. The office was created last September to comply with Bay Area Air Quality Management District regulations. In November, an employee transportation survey at the Lab determined a vehicle employee ratio of 0.84 per employee; a new target of 0.76 has been set for this year. LBL has also entered into a Trip Reduction Plan to improve air quality by reducing emissions resulting from vehicle commute trips to the work site.

Other trip reduction strategies are also being considered. For more information on current and upcoming strategies, contact Employee Transportation Coordinator Carma Hamer at X5196, or Louise Millard, program manager, at X5547.

New virus protection for Macs

Version 3.6 of Disinfectant, the popular anti-virus freeware for Macintosh, is now available on the Workstation Server. Released earlier this month, the new version detects one new virus, a clone of "nVIR-B," as well as the dozens of other viruses recognized by earlier versions.

Retrieve Disinfectant 3.6 via AppleShare in the Chooser. Select the WKSG Server in the LBL-Servers zone. Disinfectant is located in the Public Access area, in the Anti-virus folder.

PC users can protect their machines with the current version of Data Physician Plus, available on the Novell server ICSD_Nov1. Find the software in the following directory: sys:\public\dataphys\dataphy.40e

"Good Times" update

Information can be hard to kill in cyberspace. Some computer users are still receiving warnings about a non-existent e-mail virus known as "Good Times" three months after rumors about it began.

In December, computer users around the world received alerts saying there was virus-laden e-mail circulating on the Internet (see Currents, 12/16/94). The e-mail message, alerts said, had "Good Times" in the subject line; Opening the mail would infect the recipient's computer.

DOE's Computer Incident Advisory Capability (CIAC) quickly determined that "Good Times" was just a hoax. According to CIAC, there are no known viruses that can infect a computer by way of a simple e-mail message.

For a virus to spread to a computer, the file containing the virus must be executable--as in the case of a game or a screen saver. Reading an e-mail message does not involve the execution of the message, only the viewing of its text. (However, viruses can be passed in executable files that are attached to e-mail messages.)

Mark Rosenberg, LBL's Computer Protection Program Manager, says anyone receiving "Good Times" alerts should forward them to him at cppm@lbl.gov and not to co-workers. For more information on computer security or to report computer security-related incidents, contact Rosenberg by e-mail or at X6708.


LBL Open House: Create winning theme, get a prize

Now that the date and time have been set for the 1995 Lawrence Berkeley Laboratory Open House, its promotion awaits one key element--a theme.

The Open House Steering Committee is offering a reward to the laboratory employee or student who comes up with the most interesting and appropriate theme--the phrase or slogan that epitomizes the October celebration and the scientific excellence it will honor. The theme will be included in all publicity about the event.

Among the prizes for the winning entry's author will be reserved parking for one month in the work area of choice, as well as a "promotion pack" of merchandise featuring the LBL name and logo.

Only current or retired laboratory employees and currently registered students are eligible to participate. Individuals may submit more than one entry (but no duplicate entries). They should be sent to Michael Chartock, chairman of the Steering Committee, via e-mail or lab mail to arrive no later than Friday, May 19. The Steering Committee will choose a winner at its meeting on May 30.

Chartock said the theme should be brief and should serve as a "tag line" for the phrase "LBL Open House 1995." He said it will appear on posters, fliers and advertisements promoting the event, which will take place from 10 a.m. to 3 p.m. on Saturday, October 28. Residents of East Bay communities, LBL employees and their family and friends, and high school science students will be among the targeted audiences invited to the Open House.


Skin Cancer Screening Clinic
