BOULDER, Colo. — Technology is more powerful than ever before, and that power comes with a problem: heat.

Phones, laptops and other devices are prone to overheating when they work too hard. It's been a barrier to innovation for decades.

"The inability to control heat is one of the big limits in current nanotechnologies," said Margaret Murnane, a physicist at JILA, a joint research institute between the University of Colorado Boulder and the National Institute of Standards and Technology. "[It impacts] future quantum computers, and even the computers in our homes and cars."

"If you keep your laptop on your lap for an extended period of time while you're working on it, or if you're playing a game on your cell phone for a while, you will quickly find that heat management is very critical in how those devices function," said Joshua Knobloch, a postdoctoral research associate at JILA.

Knobloch and Murnane are co-authors of a recent study that may have solved a portion of the heat distribution problem.

Typically, hot metal objects need space to cool down efficiently. The researchers' work found something very different at the nano level.

"If you take an array of these very small heat sources and you tightly pack them together, they cool much more efficiently and faster than if you spaced them widely apart," Knobloch said.

The nano-sized metal bars used in the research are thinner than a blood cell. Murnane, Knobloch and the rest of the team used one of the world's most powerful computers to simulate how heat dissipated when those bars were spaced at different distances.

When the bars were packed tightly together, heat energy was forced away at a relatively high rate of speed. It's a technique that could be incorporated into electronic devices moving forward.

"In a way, it's a very timely discovery," said Mahmoud Hussein, a theorist and professor at CU Boulder's Aerospace Engineering program. "If you look at the state of industry right now, the key is going smaller and smaller, and this discovery is all about that."

High school sophomore Jadyn Lewis is seeking answers to questions concerning her community, like how climate change impacts the food we eat and why COVID-19 affects some groups more than others.

“Especially with this pandemic, people are wanting to know what’s happening exactly and the details and science behind that,” she said.

Lewis and other students across the country are now learning how science impacts everyday life through a national educational effort led by the University of Colorado Boulder.

This innovative way of studying science focuses on students’ experiences and their challenges.

“That means for Black, Latinx and indigenous students who might encounter science as a white endeavor, we want to privilege and center the experiences and work of Black scientists for example,” said Bill Penuel, Ph.D., a professor of learning science at CU Boulder, who is leading this program with help from educators at some of the most prestigious universities in the United States.

Penuel says the goal is getting students interested in science by having them ask questions about the world around them.

“By the end, they’ve learned the science ideas that are in the traditional curriculum not instead of teaching and then trying to find an application, they’re learning it really through the application,” he said.

This deeper understanding of sciences does come with a $7 million price tag, but it’s free for all students, like Lewis.

“Putting in the effort and the time and the money and the resources in order to create a curriculum for students for diverse backgrounds is crucial,” she said.

Materials taught in this program meet the Next Generation Science Standards, which is a research-based vision for science learning being put in place in classrooms across the country and allows students to get answers to the questions impacting them the most.
