Max Kiefer (Mgmt’04; OrgMgmt’21) spent the last two decades building a career as a sustainability professional, holding positions at Costar, CB Richard Ellis and Healthy Buildings International. Today he serves as the sustainability director at Wynd, an air monitoring and purification technology company operating in over 100 countries around the globe.

What was your favorite part about your time at CU?

The highlight has to be a business class I took called “Profiles in American Enterprise” that allowed undergrads to be teaching assistants to a class of 30, give a presentation to over 1,000 people, connect with CEOs — mine was Patagonia CEO Michael Crooke — and become a published author.

Could you tell us a little about what Wynd does?

What we really focus on is speciation and contextualization — basically telling you exactly what’s in the air. Our monitors and purifiers communicate with one another through connected sensors. These sensors can pull in particulate matter and tell if it’s pollen, mold or smoke from a cigarette, and instruct the purifier to respond accordingly. We then aggregate all this data in a mapping system to give consumers a report of their space’s air quality.

Why does indoor air quality matter?

People spend more time inside now, and indoor air quality can be nine to 10 times worse than outdoor air quality. Things like office buildings and apartment complexes used to be just for the owners to monitor and manage. But now, individuals have more access to data and have the power to ask questions and push for change in the places that they live, work and play.

What creates poor indoor air quality?

Poor indoor air quality often comes from simple things people don’t pay attention to: cooking, vacuuming, cleaning — even carbon dioxide from breathing. Improving indoor air quality often comes down to educating individuals on simple items to improve their space, such as opening windows. The COVID-19 pandemic also changed the way people talk about air quality. With the pandemic, we became more aware of how viruses travel through the air — and poor air quality makes that spreading even easier and compounds the ramifications.

What gives you hope for the future of air quality?

I’m hopeful that with more data out there we can continue to uncover solutions to maintaining better air quality. I’m also optimistic about the direction sustainability is heading. It’s evolving to incorporate health and wellness and environmental justice, ensuring these technologies will bring all individuals — particularly those who have been marginalized in the past — forward to the future of healthy buildings.

Materials Engineer Improves 3D-Printed Products Anonymous (not verified) Fri, 03/11/2022 - 00:00

NIST materials research engineer Callie Higgins (MElEngr’14; PhD’17) was awarded the federal government's prestigious 2021 Emerging Leaders Samuel J. Heyman Service to America Medal. She was recognized for her invention of a technology that detects and fixes microscopic flaws affecting the reliability of 3D-printed products.

What was the best part of your CU experience?

Probably the relationships I built in graduate school — the classes, labs and research aren’t easy, but when you are surrounded by people all going through the same trials, the load seems to lighten a bit. Another highlight was transitioning to a Research 1 (R1) Institute with pretty rockin’ school spirit for graduate school. My undergraduate program was at a small liberal arts college in California, the University of San Diego, where we were all too distracted by getting to live at the beach to remember our sports teams.

How do you describe your research?

The goal of my research is to help transform traditional manufacturing as we know it. We are working to develop a fundamental understanding of a technology called photopolymer additive manufacturing, with an eye on the healthcare field and tissue engineering. Our process starts with liquid material (photopolymer) that reacts with light — so that wherever you shine light, it solidifies into a 3D part you've designed. This allows you to fabricate structures with an array of chemical and physical properties that would otherwise be impossible to make.

How did you and your team first discover flaws in 3D-printed products?

To 3D print using this technology, the resins must have absorbing qualities in order to confine the printing region to a single layer. For example, think about how the heart has four chambers; if you didn't confine the light to a defined region, you’d end up with a solid, useless blob of tissue-like material. However, this requires the material to have a gradient of properties throughout every layer, where the top is stiff and the bottom is soft. You can imagine the issues that might arise if the stiff regions of one layer didn’t quite attach to the soft region of the next layer. At NIST, we're working to not only understand these regions and how they bind together, but also reverse-engineer them to produce parts with complete 3D control of their mechanical and chemical properties.

Explain how your technology aids in the 3D printing of artificial organs.

The technology we invented to detect and remedy these microscopic flaws that threaten the safety and reliability of photopolymer 3D-printed structures paves the way for the use of this technology in tissue engineering. We built a 3D printer into an atomic force microscope to understand how materials change through-out the printing process. We are now working to reverse-engineer the process to print the ideal environment for cells to develop into representative tissues (like cartilage, bone and lungs).

What advancements do you hope to see in this technology?

I am cautiously optimistic that our work is pushing the field of tissue engineering closer to producing small, representative versions of interesting tissues along the lines of kidneys, cartilage, bones and more. These mini tissue structures, or organoids, have the potential to revolutionize pharmaceutical testing and personalized medicine. What I’ve been struck by and have found wonderful about this community is its commitment to collaboration and the understanding that the only way to truly reach the full potential of this field is by working together. That has me excited, being surrounded by so many brilliant collaborators, all working towards a dream that will potentially change the world.

Are Our Kids Tech Obsessed?

Are Our Kids Tech Obsessed? Anonymous (not verified) Thu, 03/18/2021 - 00:00

CU research finds technology use in children and teens may not be as dire as many assume.

“Put your phone away!” “No more video games!” “Ten more minutes of YouTube, and you’re done!”

Kids growing up in the mobile internet era have heard it all, often uttered by well-meaning parents fearing too much screen time could spur lasting problems.

But a series of studies by ��񱦵� sociology professor Stefanie Mollborn suggests such fears may be overblown.

“What the data suggests is that the majority of American teens are not becoming irrevocably addicted to technology,” said Mollborn.

For her multi-year project, Mollborn analyzed national surveys, interviewed kids and young adults and followed 20 families over the years as their technology use changed.

Since 1997, she found, digital technology use has risen 32% among 2-to5-year-olds and 23% among 6-to-11-year-olds. Even before the pandemic, adolescents spent 33 hours per week using it outside of school.

Such trends have led to what Mollborn describes as a “moral panic” much like that which arose with the birth of comic books, radio and TV.

“We see that everyone is drawn to it, we get scared and we assume it is going to ruin today’s youth,” she said.

But as it turns out, teens have, in many ways, just swapped one form of tech for another — streaming YouTube instead of watching TV or texting instead of talking on the phone. Compared to 2002, teens spent only about 40 minutes more per week in technology-focused activities in 2016.

And in most cases, the research found, tech use does not crowd out sleep or exercise.

Surprisingly, things like setting time limits or prohibiting kids from watching shows during mealtimes appear to have no effect on how much those kids use technology as adults.

“What we do as parents matters less than most of us believe it will,” Mollborn said.

All this is not to say that no one ever gets addicted, or that parents shouldn’t talk to their kids about tech’s pros and cons.

But amid a pandemic, when even playdates have to happen on screens, her work suggests parents may have one less thing to worry about.

10 Inventions and Discoveries by CU Faculty and Alumni Anonymous (not verified) Sat, 02/20/2021 - 08:44

Grace Dearnley

As a CU student, alum or supporter, you can take pride in the amazing discoveries and inventions that have been created by people in your community. CU is full of innovators, who have changed the world in ways both big and small. Here are 10 inventions and discoveries made by CU faculty and alumni.

1. Post-it Note Adhesive

You might use them to leave reminders or label your lunch. Maybe you’re a Post-it traditionalist who uses them for the originally intended purpose — to bookmark your pages. No matter what you stick them to, you can thank CU alum Spencer Silver (PhDA&S’66). While working as a senior chemist for 3M’s Central Research Labs in 1968, Silver developed the reusable adhesive that eventually became a main component of Post-it Notes, which launched in 1980.

Learn more about the invention of the Post-it adhesive.

2. Liquid Crystals

Researchers at ��񱦵�, led by physics professor Ivan Smalyukh, have designed new kinds of liquid crystals that mirror the complex internal structure of some solid crystals. The group’s findings, published in the journal Nature, could one day be used to create new, more energy efficient types of smart windows and television and computer displays.

Learn more about liquid crystals.

3. 3D Printing

Late one night in 1983, CU alum Chuck Hull (EngrPhys’61) made a scientific breakthrough with his creation of a small plastic cup. Although seemingly unassuming, the cup was the first object to be created using stereolithography, better known as 3D printing. Hull’s discovery became the basis for the 3D printing that is a common practice across industries and homes today. After securing a patent for stereolithography in 1986, he founded his company, 3D Systems. Hull is now a member of the National Inventors Hall of Fame.

4. Dry Fogger

In 1982, after freezing solid the set of Michael Jackson’s “Thriller” video for 20 hours, CU alum Jim Doyle (Thtr’78) thought there had the be a better way to create fog than with liquid nitrogen. Doyle got to work and created a fog machine, which quickly became the industry standard. By 1986, Doyle’s dry fogger was used on the opening night of Alice Cooper’s “Nightmare Returns” tour. Later, Doyle received a 1992 Academy Award for its use in Terminator 2.

Learn more about the dry fogger.

5. Inhalable Measles Vaccine

In 2010, a team of researchers led by CU chemistry and biochemistry professor Robert Sievers developed an inhalable measles vaccine, which works when patients breathe in a puff of dry powder. One main goal of the inhalable inoculation is to mitigate needle use, as needles can be scary to some and can pose difficulties in disposal.

6. Lasers

In 1960, CU alum Theodore Maiman (EngrPhys’49) developed the laser with the help of his research assistant Charles Asawa. At the age of 32, Maiman had invented an essential technology that is now used across all aspects of life, ranging from manufacturing to surgery to grocery store checkout scanners. Maiman was inducted into the National Inventors Hall of Fame in 1984.

Learn more about the invention of lasers.

7. Bose-Einstein Condensate

In 1995, in a laboratory at JILA, a joint institute of ��񱦵� and NIST, ��񱦵� physics professor Carl E. Wieman and colleague Eric A. Cornell, a research physicist and NIST fellow, led the team that produced the first Bose-Einstein condensate, which is a group of atoms chilled almost to absolute zero. When a group of atoms is in this state, they begin to act as though they are a single atom, which lends itself to superconductive properties. For this discovery, Wieman and Cornell were awarded the 2001 Nobel Prize in Physics.

8. TiVo

You’re living in the age of Netflix, Hulu and HBO Max, so it might be hard to remember what having cable is even like. But before the streaming giants took over, TiVo was a leader in on-demand television. In 1997, CU alum Jim Barton (ElEngr, CompSci’80; MCompSci’82) and business partner Mike Ramsey founded what would become TiVo, which was best known for the device that allowed viewers to record and save television programs onto a hard drive for later viewing, and to pause and rewind live TV.

Learn more about the invention of TiVo.

9. Quantum Squeezing

In their efforts to better understand dark matter — the substance that likely makes up most of the universe’s mass — a group of scientists, including many at CU’s JILA research institute, developed quantum squeezing. In February 2021, led in part by CU alum Daniel Palken (MPhys’18; PhD’20) and NIST fellow Konrad Lehnert, the scientists found that their new approach to searching for axions allows them to better separate the signals of axions from the less relevant signals of quantum fluctuations. All this is to say that this method puts the scientific community one step closer to understanding the mysterious dark matter.

Learn more about quantum squeezing.

10. Body Battery

In 2021, Jianliang Xiao, a mechanical engineering associate professor at ��񱦵�, created a small, wearable device that uses thermoelectric generators to convert body heat into power. The device is made from polyimine, a material that is stretchy and can heal itself. The hope is that this fully recyclable gadget can someday help power fitness watches and other wearable devices.

Could Laura Devendorf’s high-tech fabrics change the way we express ourselves?

Laura Devendorf has a ready answer for how she spent the summer: The ��񱦵� information scientist taught herself how to weave, an experience equal parts relaxing and infuriating — “like brushing doll hair forever,” she said.

On any given day in Devendorf’s lab, part of the university’s ATLAS Institute, where students and faculty commonly mix art and science, you’ll find at least three wooden looms — the old-fashioned kind with a hand-operated shuttle. They sit next to circuit boards, wires and other high-tech toys.

That’s because Devendorf, an ATLAS fellow and CU assistant professor since 2017, is diving into the zeitgeisty field of smart textiles — fabrics that look and feel like wool and cotton but exhibit dynamic properties.

Last year, designer Julianna Bass made waves at New York Fashion Week when she introduced a line of garments that changed color as models sauntered down the catwalk. Google’s Project Jacquard recently teamed up with Levi’s to design a denim jacket that lets you answer your phone by simply tapping the sleeve.

But Devendorf has a distinct attitude toward wearable technology, inspired by her eclectic interests in art, sustainable design and feminist theory. She’s more interested in expressive potential than utilitarian value. In this vein, she’s exploring how clothing can connect our bodies to the environment, for example, or reveal and record influences on the body as an aid to memory and reflection.

Rather than developing technologies of convenience, she said, she’s interested in “whether or not it’s possible to build a different kind of relationship with technology that’s slower and more thoughtful.”

Old Meets New

Although Devendorf has a bachelor’s degree in computer science and enjoys writing code, she is in some ways an odd fit for the world of smart textiles. She’s skeptical about aspects of tech culture and is predisposed to physical craftsmanship. She once spent a summer drawing handmade cards for tourists in Santa Barbara, Calif., seemingly more in tune with another of her degrees, in art.

“My husband says I have an analog fetish,” she said. “I still collect vinyl. I like sending letters in the mail. I don’t really like technology, but it’s not going away. So my focus is how do we do something more interesting with it?”

Much of that old-meets-new tension is embodied in a special delivery Devendorf is expecting this fall: A custom-made TC2 Jacquard loom. The device looks more like a 3D printer than one of the doll-hair combers in her lab now, and can seamlessly weave more complex patterns of traditional textiles and high-tech threads, such as wires coated in thermochromic pigments that change color in response to an electric current.

Among the projects Devendorf can carry forward with this computer-meets-loom is Ebb, a fabric she helped invent as a graduate student at the University of California, Berkeley. It interlaces ordinary yarn with thermochromic threads, yielding a fabric with designs that can morph from purple to pink to white within seconds. Devendorf has experimented with designing Ebb shirts that change color as the skin undergoes tiny shifts in sweatiness — like a human blush in cloth.

Purple to pink to white in seconds.

These subtle changes can indicate various types and degrees of excitement — from physical exertion to mere anticipation, true anxiety, even sexual arousal. Ebb-based garments would manifest how the wearer is feeling, signaling a change for all to see.

“We have five senses,” she said. “Smart textiles can partner with those and give you this other sense.”

Because smart textiles make public what might otherwise be private, and because clothing is more intimate than a phone you can set down and ignore, Devendorf approaches these projects with caution. “It represents you to the world.”

Steven Frost, an instructor in ��񱦵�’s College of Media, Communication and Information who has collaborated with Devendorf, said she has a rare ability to blend technology and artistic creativity.

“What’s really exciting about working with Laura is that she really does speak both languages,” Frost said.

Devendorf helped invent a fabric that interlaces ordinary and thermochromic threads.

The Pressures On Us

Much of Devendorf’s recent work focuses on a topic she thinks about a lot: Parenthood. The mother of a 2-year-old and a 5-year-old, she describes it as a vulnerable experience.

And while many technologies aimed at parents seek to ease stress, Devendorf embraces the vulnerability.

At a May workshop at the Boulder Museum of Contemporary Art, she asked participants to design what she called an exoskeleton for caregivers — think an Iron Man suit for people covered in baby vomit. The group’s ideas included small, autonomous robots that would crawl over your body to clean your clothes and a hoop skirt that could double as a playpen for toddlers.

Speaking two languages: Art and science.

Devendorf herself is interested in using technology to lay bare the tensions inherent in parenthood — including the fact that, as a mother, she often feels like her body isn’t her own. In her free time, she’s been crocheting a poncho made of pacifier nipples to make visible a common feeling among nursing mothers.

She’s also begun developing a drape with small pressure sensors to record how parents hold their newborns, allowing production of maps showing the evolving physical relationship between parent and child.

“I like the idea of how our memories might change if we remember the pressures on us,” she said.

Ultimately, Devendorf hopes more technology will move in this direction — enhancing how people experience reality and caretaking rather than alienating them from it.

“So much of technology is about self-realization and no longer having to struggle or care for anything because you have the technology to do that,” she said. “I like the idea of actually amplifying that struggle instead, because maybe that’s where the meaning comes from.”

From Cup to Kidney

Working late one night in 1983, Chuck Hull (EngrPhys’61) thought he’d made a breakthrough. The engineer phoned his wife, Anntionette, at their California home and asked her to drive to his lab to look at a small plastic cup.

“She said something to the effect of ‘no way,’” he says, chuckling.

But a breakthrough it was: The humble cup was the first object ever created via stereolithography — better known today as 3D printing. Hull had fashioned a three-dimensional shape by layering two-dimensional “slices” of a liquid, acrylic-based material hardened by ultraviolet light.

The discovery would become the foundation of a technology that’s now ubiquitous, from breadbox-sized printers used by hobbyists to refrigerator- sized printers used in healthcare, manufacturing and aerospace design. (Above: a 3D-printed model kidney.)

After graduating from CU, Hull took a job with a DuPont subsidiary developing analytical tools for chemists, then moved to a smaller firm that applied thin resin coatings to tabletop surfaces. The coatings cured instantly when exposed to ultraviolet light, which got him thinking about how the technology might be used to make 3D objects.

Hull convinced his boss to let him use a small lab on nights and weekends for experimenting on his own time. After more than a year of tinkering with liquid plastics, his labor paid off.

Hull secured a patent for stereolithography in 1986 and soon founded a company, 3D Systems. Initially, he saw the technology primarily as a way of prototyping objects, such as automotive parts, more efficiently. Over time, the business expanded into custom medical devices and a wide range of consumer products.

Now 76 and a member of the National Inventors Hall of Fame, Hull is still involved in the day-to-day operations of 3D Systems, which opened a 70,000-square foot healthcare tech facility in Littleton, Colo., earlier this year. The company recently helped surgeons reconstruct the facial bones of a young man injured by a landmine in Zimbabwe — a reminder of how far technology can come in three decades and the good it can do.

At CU-Boulder’s Idea Forge, students imagine the future. Then they build it.

The smell of cherry pie carries a hint of metal and oil. Machines grate, drills whirr. The space, bright, open and airy, has high ceilings, concrete floors and long wooden tables.

It’s March 13, the eve of Pi Day (3-14) — hence the pie. Some students eat. Others, masked in safety goggles, attend to hungry grinding machines. Eric Fauble (MMechEngr’15), a graduate student from Golden, Colo., is building a device that simulates microsurgery, a practice tool for neurosurgeons.

Fauble’s work exemplifies what this inventor’s paradise, the Idea Forge, is all about.

“It’s a place where students of every major are welcome and can become familiar with technology and build things, interact and learn things accidentally,” says Idea Forge initiator Diane Sieber, an associate dean in the College of Engineering & Applied Science.

CU-Boulder Engineering already had a machine shop and another hands-on lab, but they are reserved for engineering students only. The Idea Forge, located in the remodeled east wing of the old Fleming Law Building, is open to all students who partner with an engineer, fostering cross-disciplinary innovation.

At the Idea Forge, students of all majors can be inventors.

“I believe strongly in the educational value of tinkering and learning publicly,” says Sieber. “One of our instincts is to hide what we don’t know, but here students can enjoy not knowing and instead learn from one another and make things from initial concept to prototyping to manufacturing to selling.”

Taylor Scott (MechEngr’15), a senior mechanical engineering major from Fort Collins, Colo., has been hard at work. He and partners developed a tool to aid data collection related to cruise ships’ fuel consumption. With another team, he devised a way to make solar panels more energy efficient and less expensive, potentially helping developing-world farmers replace diesel-powered irrigation systems with solar-powered systems.

“By making solar irrigation more affordable, we increase the incomes of farmers and the standard of living in communities,” says Scott.

The Forge came to fruition quickly. Sieber prepared a proposal over winter break in 2013; the space opened nine months later, after extensive remodeling largely sponsored by the College of Engineering.

“It had been vacant for about five years. There was graffiti on the walls. It was a forgotten place,” says Daria Kotys-Schwartz, a mechanical engineering professor who also directs the Forge. “But if you had vision you also knew it had immense potential if we weren’t constrained by closed thinking. We walked through and imagined ‘what if.’”

The result is a 22,000 square-foot, multi-purpose invention lab with band saws, milling machines, drills, sanders, routers and soldering stations, along with welding and meeting rooms, a classroom, offices and prototyping capabilities.

Alex Kreilein (TeleComm’15), a PhD candidate in interdisciplinary telecommunications from Milwaukee, happened upon it almost immediately. Also an entrepreneur who advises clients on mobile app development and information security, Kreilein says he’s deepened his understanding of project management and human-centered design by mixing with mechanical engineers.

“Without Idea Forge, I’d have to spend hundreds of dollars a month on a co-working space that’d likely be filled with people who think just like I do,” says Kreilein.

Students also benefit from skilled Forge personnel, including a machine shop manager-machinist, instructor and lab engineer. Plans call for a full-time electronics lab engineer and assistant machinist.

Amy DeCastro (ApMath’15), an applied math student and self-taught welder from Westport, Mass., oversees the Forge’s welding shop.

“The projects seem endless — from little tiny aluminum turbines to 20-foot-long stainless-steel heating systems,” she says. “The first time I saw the welding room I thought I’d spontaneously combust with joy. I feel really excited every time I come here.
