This summer Kenneth Snelson's "Mozart I" was installed on the front lawn of the Packard Electrical Engineering Building. The stainless steel beauty previously resided outside of Meyer Library, where it was installed in 1983.

Snelson's sculptural works are composed of flexible and rigid components arranged according to the idea of floating compression. The height and strength of Snelson's sculptures, which are often delicate in appearance, depend on the tension between rigid pipes and flexible cables.

In a 2002 interview, Prof. Jeffrey Schnapp states, "[Snelson's] work is centrally concerned with issues of compression structure, and [his work] represents a very distinctive attempt to bring together the realm of engineering, sciences, and the art of sculpture."

 

A second Snelson sculpture, "Six #1" can be experienced at the Li Ka Shing Center.

Snelson's works are in permanent collections including the Metropolitan Museum of Art, New York, the Museum of Modern Art, New York, the Whitney Museum of Modern Art, New York, the Art Institute of Chicago, and Stanford University.

profs Bill Dally and Andrea Goldsmith
September 2021

Professor Bill Dally and Emerita Professor Andrea Goldsmith have been selected to serve on the President's Council of Advisors on Science and Technology (PCAST). The council consists of distinguished individuals from sectors outside of the Federal Government who advise the President on policy matters where the understanding of science, technology, and innovation is key.

PCAST develops evidence-based recommendations for the President on matters involving science, technology, and innovation policy, as well as on matters involving scientific and technological information that is needed to inform policy affecting the economy, worker empowerment, education, energy, the environment, public health, national and homeland security, racial equity, and other topics.

Not only are its members brilliant and esteemed, they represent the most diverse PCAST in U.S. history. PCAST is traditionally co-chaired by the President's Science Advisor and 1-2 external co-chairs. Since its inception, no women have served as co-chairs. President Biden's PCAST has two women co-chairs. Furthermore, this PCAST reflects the President's commitment to build an Administration that truly looks like America. For the first time ever, women make up half of PCAST and people of color and immigrants make up more than one-third of PCAST. Its diversity will help the council bring to bear a wide range of perspectives to address the nation's most pressing opportunities and challenges, so that science, technology, and engineering benefits all Americans.

 

Please join us in congratulating Bill and Andrea!

For decades, the general-purpose central processing unit—the CPU—has been the workhorse of the computer industry. It could handle any task—literally—even if most of those capabilities were unnecessary.

This model was all well and good as chips grew smaller, faster and more efficient by the day, but less so as the pace of progress has slowed, says Professor Priyanka Raina, an expert in chip design. Priyanka says that to keep chips on their ever-improving trajectory, chip makers have shifted focus to chips that do specific tasks very well. The graphics processing unit (GPU), which handles the intense mathematics necessary for video and gaming graphics, is a perfect example.

Soon, there’ll be a faster, more efficient chip for every task, but it’ll take industry-wide cooperation to get there, as Priyanka tells listeners to this episode of Stanford Engineering’s The Future of Everything podcast with host Russ AltmanListen and subscribe here.

Prof. Eric pop
September 2021

Professor Eric Pop's lab - Pop Lab - took a long shot adapting phase-change memory (PCM) to plastic substrates – turns out the energy-efficiency significantly improved compared to PCM on conventional silicon substrates.

Phase change materials leverage changes in structure into differences in electrical resistance that are attractive for computer memory and processing applications. Khan et al. developed a flexible phase change memory device with layers of antimony telluride and germanium telluride deposited directly on a flexible polyimide substrate. The device shows multilevel operation with low switching current density. The combination of phase change and flexible mechanical properties is attractive for the large number of emerging applications for flexible electronics.

"It's the same atoms as conventional phase-change memory but in beautiful striped alternating thin layers, also known as a superlattice," says Professor Eric Pop.

Eric's group put arrays of memory cells made of superlattices of alternating layers of antimony telluride and germanium telluride on flexible plastic substrates. They were curious whether they could make it work—flexible memory is a key enabling technology for electronic skin, lightweight environmental sensors, and other unconventional electronics. Once grad student Asir Intisar Khan and postdoc Alwin Daus figured out how to make these devices at temperatures that would not melt the polyimide substrate, the researchers were surprised by what they found.

"The flexible substrate provides an extra advantage we did not anticipate," reports Eric Pop. The current density required to switch the flexible memory cells is 10 to 100x lower than any previously reported phase-change memory, and the memory cells maintain their performance when the substrate is bent. After seeing the results, the team was "scrambling," he continues. "Why is this better?" The Stanford group believes that the layers in the superlattice, the cell's "pore-like" design, as well as the insulating properties of the plastic substrate, help confine the energy applied to the memory cells, making them heat up more efficiently and spurring a phase change at lower electrical currents.

Professor Shanhui Fan and EE alum, Professor Aaswath Raman (UCLA) are using their technology to potentially reduce heat-related deaths. As higher temperatures become more frequent, the use of air conditioning increases, resulting in a cycle of baking the planet in an attempt to keep people cool.

Pictured are Aaswath Raman as a graduate student (on the left) with Professor Shanhui Fan in 2011.

Shanhui and Aaswath developed a film that was both highly reflective of visible light—so it wouldn't warm up in the sun—and an excellent emitter of infrared radiation at just the right wavelengths to pass through the atmosphere unimpeded. If the film covered the hood of a car, it would conduct heat away from the hood, cooling it without using any electricity.

Since they published their findings in 2014, other researchers have designed paints, gels, and wood that can remain cool in daylight. In 2020, their film was installed on a supermarket roof, resulting in energy savings of 15-20 percent.

The film is currently being tested on a few bus shelters in Tempe, Arizona. Preliminary results show that the roofs can be 30 degrees cooler than the surrounding air.

Today, Professor Aaswath Raman is involved in a UCLA project called Heat Resistant Los Angeles. "The idea is, can we go beyond shade?" he says. Historically, cities have focused on providing shade trees, parks, and green belts to help cool urban environments, but such projects often bypass low-income communities and take years to establish. Raman envisions using canopies coated with his film to cool large outdoor spaces; these could be set up quickly at a relatively low cost.

"It's very early days for the project," he says, "so it's still kind of speculative. But I'm hoping in a year or two we'll have some cool results and demos to share."

 

The World Health Organization estimates that between 1998 and 2017, heat waves killed at least 166,000 people around the world. If we continue to emit greenhouse gases at the current rate, deadly heat will put more than a billion people at risk by the end of the century.

The technology may ultimately help cool our cities, and it may be able to prevent tens or hundreds of thousands of deaths from the brutal heat waves to come, which would be no small feat. But to cool the whole world, we've known for decades what needs to be done: Leave fossil fuels in the ground.
