There is a theory floating out in the scientific community which posits that the slipperiness of ice and the infamous hole in the ozone layer above the Antarctic are the result of the same phenomenon. According to this theory, despite the term "frozen solid," the surface of ice is actually "wet."
This theory has received a big boost with the discovery by Berkeley Lab researchers that even at temperatures far below those in the Antarctic atmosphere, the surface of solid ice remains covered by a thin film of quasi-liquid water.
Ice has a uniquely low coefficient of friction, which is why skaters can glide so swiftly across it. The long-time explanation for this anomaly was that pressure--for instance, from the weight of a skater on a pair of sharp-edged blades--liquefies the surface layers of water molecules. However, modern methods of testing have proven that pressure is not the answer.
Other studies have provided evidence that solid ice is wet on the surface at 230 K (-43 degrees Celsius below the normal freezing point of water) but there has been too little information on the configuration of these water molecules to draw any firm conclusions.
Now, researchers with the Materials Sciences Division (MSD), in collaboration with French and Dutch scientists, have produced the first detailed molecular-scaled pictures of the surface of crystalline ice. These pictures reveal that even at 90 Kelvin (-183 degrees Celsius), water molecules on the surface of ice continue to vibrate, giving the surface a "quasi-liquid" character that could account for catalytic chemistry, as well as slipperiness.
"Our analysis of solid ice showed that at 90 K, water molecules on the surface are bound in a lattice but aren't frozen like those in the layers beneath them," says MSD chemist Michel Van Hove. "Water molecules in this surface layer have an unusually high degree of vibrational motion with amplitudes several times that seen in water molecules buried deeper within the bulk of the ice."
The high degree of vibrational motion exhibited by water molecules in the surface layers of ice is attributed to the absence of other water molecules above them, together with the weakness of the bonds between water molecules. This not only gives rise to a liquid-like vibrational motion, it also frees the water molecules to interact with other molecules to which they are exposed, such as those in the atmosphere.
Temperatures in the polar stratospheric clouds are around 200 K (-73 degrees Celsius). Van Hove and his colleagues believe there are enough vibrating layers of water molecules to create a thin film of quasi-liquid water on the ice crystallites in the clouds.
"This watery film could be the catalyst that provides a crucial link in a long chain of chemical reactions leading to the creation of the ozone hole," says Van Hove. At temperatures around 230 K and above, Van Hove thinks that the surface film of ice becomes a true liquid, which would account for its uniquely low coefficient of friction.
The molecular-scale images of the surface of ice were produced at the Center for Advanced Materials by the research groups led by Van Hove and chemist Gabor Somorjai. The researchers created a thin film of "ideal" ice (about ten angstroms thick) by condensing water vapor on a cold platinum surface in an ultrahigh vacuum. They then "bounced" low-energy electrons off the surface of the ice and studied the resulting diffraction patterns using a technique Van Hove developed called "tensor-LEED (for low-energy electron diffraction). This technique provides researchers with a timely and practical means of determining the position of atoms on a given surface.
"With tensor-LEED, a simple surface structure that would have taken us months to resolve can now be determined in less than a day," says Van Hove.
Once models of the surface structure of ice were obtained, the results were analyzed by Christian Minot in Paris, using total-energy calculations, and Geert-Jan Kroes in Amsterdam, using molecular dynamic simulations.
"What we see is that the outermost molecular film of ice solidifies only up to a point," says Van Hove. "Large vibrational amplitudes continue to exist down to at least 90 K."

On Thursday, Dec. 12, Berkeley Lab will hold an Open House. And although it will be 3,000 miles away on a different "Hill," it will be showing off technology that closes the distance gap--virtually.
The Open House will be the first for the Lab's Washington, D.C., Projects Office since moving into new energy-efficient offices on Maryland Avenue just a few blocks from the Department of Energy's headquarters in the Forrestal Building. The event will enable Berkeley Lab to share its capabilities with Washington-based program managers whose belief in us makes our work possible. It will also allow us to showcase some of the latest scientific supercomputing and networking technologies.
The Washington, D.C., office was established in 1993 to better serve the research and policy analysis needs of the DOE and other federal agencies and provide facilities and support (both long and short term) for Berkeley Lab staff working in Washington. Fourteen Berkeley Lab researchers and support staff currently work there, primarily on energy efficiency programs sponsored by DOE and the Environmental Protection Agency. These projects range from assisting federal agencies in the purchase of energy efficient products, to conducting technical studies and market analyses for voluntary programs such as Motor Challenge and the familiar Energy Star labels program.
Energy efficient lighting and office equipment are an integral part of the new suite, which has a large conference room that can hold more than 75 people. The Washington Office Seminar Series, organized by Heinz Heinemann, features active Berkeley Lab researchers speaking on topics of current interest. Since September, lectures have featured Paul Alivisatos on nanocrystals, Mina Bissell on the role of the extracellular matrix in human breast cancer, Bo Bodvarsson on the geological disposal of nuclear waste, and Bill Morris on thin-film conductors.
The late afternoon Open House will feature a live video conference between the two Berkeley Lab sites via an MBone video link over the Internet; a live demonstration of an experiment at the Advanced Light Source being conducted remotely via the Internet; and 3-D presentations of scientific data in the new Visualization Laboratory.
These featured technological capabilities all fit within a new and ambitious program at DOE called "DOE 2000." Its goal is to set the standard for R&D organizations into the 21st century by providing tools that eliminate physical distance and organizational structure as limits to collaboration. As the Washington hub for Berkeley Lab's distributed scientific supercomputing capabilities provided by NERSC and Esnet, the office places these capabilities on the doorstep of DOE and other interested agencies. In this way, Berkeley Lab can work in close proximity with DOE to achieve the vision of a networked R&D enterprise that is more productive and cost effective as technology eliminates the barrier of physical distance. And that, after all, is what Berkeley Lab's Washington, D.C., Projects Office is all about.
Berkeley Lab employees traveling to Washington are invited to conduct their business in the Projects Office. It is located at 1250 Maryland Ave., S.W., Suite 500. Contact Moira Howard-Jeweler (202-484-0885, mchoward@ lbl.gov) to make your arrangements.

Mass manufacturing and high speed computer networks--exploit both and you will build the supercomputer of the future. That's the conviction of researchers at the Lab's National Energy Research Scientific Computing Center (NERSC).
Joining with UC Berkeley's Computer Science Division and Sun Microsystems, NERSC will develop a unique networked cluster of largely off-the-shelf equipment that will be put to work by scientists and then evaluated. Many here believe this COMPS (Cluster of Multiprocessor Systems) project will serve as the architectural blueprint for the next generation of supercomputers.
Initially, the COMPS prototype will consist of three Sun SMP (symmetric multiprocessor) computers connected together and to the world via a mix of lighting-fast networks. Two will have eight processors (CPUs) and the third will have two-to-four processors. In order for these relatively inexpensive machines to function as a supercomputer, systems software and network technology must be developed that allows the 18-20 CPUs on the three separate computers, along with multiple memory storage units, to function as though they were a single machine. The challenge is formidable.
To succeed, researchers must overcome the communication delay or "latency" inherent when clusters of computers are linked together via a network. Anybody who has downloaded a World Wide Web page is familiar with such delays. To speed up the flow of information between machines, multiple 622 megabit/second ATM networks will interconnect the Sun computers as well as link them to scientific instruments. Another type of network technology, SCI (Scalable Coherent Interface), will be used to accelerate the progression of parallel programming tasks and exchange of information between the many processors.
NERSC, home to the most powerful combination of unclassified computing and networking resources in the United States, will host the COMPS project. Lead scientists on the project include Horst Simon, who heads the NERSC Division; William Johnston, who heads ICSD's Imaging and Distributed Computing Group; David Culler, UCB Computer Science Department professor and NERSC researcher; and Greg Papadopoulos, vice president and chief technology officer for Sun.
Sun, which has provided two Enterprise 4000 computers, is making its entry into the field of supercomputers with this project.
COMPS is being launched at a time when the future design of high performance computers is particularly uncertain. The architecture of high performance computing systems ranges from machines with a few powerful vector processors to massively parallel machines with thousands of processors to networks of single-processor workstations, and now to COMPS, a network of multiprocessor workstations. As for the processors used in these different machines, they can be inexpensive off-the-shelf commodities or unique, custom-made CPUs costing tens of millions of dollars.
Simon says NERSC has a major stake in helping to resolve the architectural puzzle posed by the current array of choices.
"What is the most efficient and inexpensive way to put together a set of components to do supercomputing?" he says. "Clusters of symmetric multiprocessor systems have demonstrated their supercomputing potential. What we're now seeking to determine is whether COMPS provides a price and performance advantage for NERSC users. Our approach is to network clusters of SMP machines that use off-the-shelf, inexpensive processors. What NERSC needs to determine is whether this approach really can provide capability computing for a large national user facility."
Culler has tackled the problems of transforming a cluster of workstations into a single system. He heads the Network of Workstations (NOW) project, which links 140 single processor workstations within UCB's Soda Hall. COMPS differs from NOW in that it links multiprocessor workstations. Yet many of the communications issues involved are similar.
Johnston heads a team that is creating virtual laboratories, using the Internet to make unique scientific equipment accessible from all over the world. Collaborators at different locations can conduct an experiment and discuss results while it is in progress. Like Culler, Johnston too must contend with the issue of communications latency if true remote control of machines is to be achieved.
"Scientific experiment instrumentation control is increasingly using `machine intelligence' approaches to automate experiment control functions through the real-time analysis of experiment data, which is also a very computationally intensive process," says Johnston. "It is our hypothesis that the COMPS architecture will be capable of addressing both the traditional numerical computation, and the rapidly increasing needs of the experimental science community for high performance computing and storage. Further, all of these scientific computing activities can use, and will benefit from, a common and incrementally scalable computing system architecture that can be widely distributed around the new high-speed, wide area networks."
The COMPS prototype will be developed and tested through actual use by scientists. In one project, 200 megabit/second data streams from physics detector experiments will be fed to COMPS for analysis. A second test, this involving a "machine intelligence" based control system, will analyze live digital video from an electron microscope at the National Center for Electron Microscopy. COMPS also will be used for the on-line analysis and control of an ultra-high resolution micro-spectroscopy instrument at the Advanced Light Source.
All employees are invited to attend the
Director's Annual Holiday Reception
from 3:30 to 5 p.m. on Tuesday,
December 10, in the cafeteria.
The Laboratory Music Club's chamber group will provide entertainment;
refreshments will be served.
Jane Long, head of the Earth Sciences Division's Environmental Remediation Technology Department, has been named dean of the University of Nevada, Reno's Mackay School of Mines. She will be consulting dean to the school for the remainder of this school year, and will assume the post full time on July 1, 1997. Long says her goals are to establish joint programs with the mining industry in Nevada and enhance the school's research programs.
It has been widely accepted in the scientific community now that an asteroid or a comet crashing to Earth 65 million years ago triggered the extinction of the dinosaurs. But there have been other mass extinctions in our planet's history, starting with the greatest of all 250 million years ago at the Permo-Triassic boundary. At this year's annual meeting of the Geological Society of America, a University of Oregon paleontologist reported what he claimed was "the first unequivocal evidence of an impact" implicating a comet or an asteroid in the Permo-Triassic extinction. The evidence offered is tiny grains of quartz excavated from the Permo-Triassic boundary that display the cracks and fractures created by the shock of a titanic impact. Similar "shocked quartz" grains were found at the Cretaceous-Tertiary boundary marking the great dinosaur die-out.
If this claim holds up, it might stir new interest in a theory proposed in 1984 by Berkeley Lab physicist Rich Muller. The theory posited that the periodic mass extinctions that have occurred throughout Earth's history are the result of comet storms unleashed upon the inner solar system by the close passage of a companion star to the sun. This companion star was dubbed "Nemesis" after the Greek goddess of retribution. One of the arguments against Nemesis has been that the only evidence found thus far to link an extraterrestrial collision with a mass extinction has been at the Cretaceous-Tertiary boundary.

Did you know that Berkeley Lab is the second largest employer in Berkeley and the twelfth largest in Alameda County? Did you know that the overall annual financial impact on the economy of the San Francisco Bay Area attributed to Berkeley Lab activities is $549 million?
These and many other facts are available in a new report entitled "Economic Impact Analysis." Jointly produced by Berkeley Lab's Technology Transfer Department and Community Relations Office, the 27-page report provides a detailed analysis of the financial impact that the Laboratory has on a local, state, and national economic level.
Setting aside for the moment the contributions of science, this Laboratory
still wields a hefty clout on the local money scene. Nearly 60 percent of the
workforce resides in Alameda County, and 30 percent in Contra Costa County.
Factor in the more than 1,700 scientists who visit the lab each year (often
bringing their families with them), as well as the 1,500 retirees and survivors
who receive benefits from the Lab, and you have thousands of adults
re-distributing the wealth. Furthermore, the Lab is a major customer of local
businesses and contractors, expending nearly $100 million for goods and
services each year. This report, PUB-782, is available free through Tech
Transfer Department at X6467.

Undoubtedly, PBS has no intention of replacing America's favorite frog, but a production crew for the network's "Scientific American Frontiers" will be here next week to look at frogs. These frogs are the freeze-resistant variety of wood frogs that were used in experiments by UC Berkeley's Boris Rubinsky to study how some animals are biologically equipped to survive in frozen environments. The MRI pictures of these frogs served as the basis for Berkeley Lab's "Virtual Frog," the famous computer image that is used by thousands of students off the Internet in schools across the country. The PBS crew will tape a re-enactment of how the images were obtained working with Katie Brennan at the Center for Functional Imaging.
"Scientific American Frontiers" is a monthly science news magazine show
narrated by actor Alan Alda of "MASH" fame. The program airs on Wednesday
nights at 8 p.m. and has a national audience of some 20 million students and
165,000 teachers.

You would never guess from her demeanor that Yamilet Rodrigues is part of a major national research project. Quiet and soft-spoken, the 24-year-old recent college graduate from Puerto Rico simply considers herself lucky to be working at Berkeley Lab.
"This is a unique experience for me, to have the opportunity to work at a major national laboratory in the United States," she said in impeccable English, which she picked up mostly by watching TV and participating in internship programs. "I learned a lot about scientific research. In Puerto Rico we don't have a lot of resources or opportunities for research."
As it turns out, her work as part of the Science and Engineering Research Semester (SERS) program not only advanced Rodrigues' own academic and professional career, but also the status of a major DOE project--the Comprehensive Epidemiological Data Resource (CEDR) program, which tracks data from DOE epidemiological studies. The information gleaned from this project is used to assess the impact of radiation exposure and to improve existing radiological protection standards.
"It is difficult to overstate the importance of her work to the CEDR program," said computer scientist Allan Konrad, her mentor at the Lab.
A computer science major from Metropolitan University in Puerto Rico, Rodrigues has worked for the past six months as part of a three-person team to provide public access to CEDR data. Her main contribution to the project is the development of Java applets--tiny applications that make the data accessible on the World Wide Web. She has also helped make it possible to browse and do keyword searches of DOE records on the Web.
For many years DOE has collected data from studies of populations exposed to radiation, including those who may have been exposed to atomic tests conducted during the 1940s and '50s. Although many descriptive studies on the subject have been published, the data itself was difficult to obtain and unavailable on the Web. The CEDR program was created to make this data, as well as "metadata," or descriptive information, available to the public and to independent researchers outside the government.
"Through Yamilet's efforts," Konrad said, "the world now has access to both the data and the metadata. She has been involved in every aspect of the program. Her work and that of the other students in the program has advanced the work of CEDR immeasurably."
Rodrigues' work is sponsored by the national SERS program, which is run locally by Berkeley Lab's Center for Science Engineering Education. Through SERS, undergraduate students and some recent graduates nationwide have the opportunity to work as part of applied research programs at world-class research facilities throughout the country.
This is Rodrigues' third internship, having spent the previous two summers at Sandia National Laboratory in New Mexico. She started working at Berkeley Lab over the summer and continued with the SERS program through the Fall semester. She will return home in December to pursue graduate studies in Puerto Rico, but not before enjoying the lighter side of her internship experience--trips to Yosemite, Lake Tahoe and Las Vegas.
During her remaining few weeks in California, Rodrigues will continue to pore over her computer in Bldg. 50, side-by-side with other computer scientists. For all she has learned and contributed during her short stay at the Lab, Rodrigues is keenly aware that her work has just begun.
"I now realize just how much more there is to learn," she said with a smile.
All Laboratory employees are invited to attend presentations by 15 student interns who are participating in research projects at the Lab. The students are concluding their work as part of the Fall 1996 Science and Engineering Research Semester (SERS) program, hosted by the Center for Science and Engineering Education.
Sponsored by DOE, the project matches undergraduates with mentor scientists at the Lab and UCB campus in order to encourage the students to pursue advanced degrees in science and engineering. Students' areas of interest span the spectrum from atomic physics to biological and environmental studies.
CSEE would like to thank the mentoring scientists and the entire Lab staff for their continued support and assistance with the program throughout the semester.
The presentations will take place on Tuesday, Dec. 10 and Wednesday, Dec. 11 in the Bldg. 50 auditorium. You are invited join the students and learn about their research experience at the Laboratory.
