DEAN’S MESSAGE

Programs to meet changing industry needs, students wise to the work world, inventions leading to patents, startups and life-changing products…

Succeeding Today and Investing in Tomorrow, in Every Possible Way

WHAT A TIME to be part of the UA College of Engineering! Engineering Design Day 2017 perhaps best illustrates the excitement. From an exoskeleton that helps a person walk to a UAV that pollinates date trees 10 times faster than usual, more than 100 senior projects were on display May 1 for the world to see. Thousands crowded into the Student Union as alumni from throughout the United States marveled at how engineering education has changed, schoolchildren caught a glimpse of their futures, industry partners and team mentors applauded jobs well done, and judges from the ranks of professional engineers chose the best projects for more than $25,000 in sponsored prizes. Remember the proverbial engineering welcome message: “Look to your left; look to your right. Those students will not be here next year”? Those days are long gone. Four- and six-year graduation rates are at a 15-year high and far above national averages, student retention is well beyond expectations and job prospects are looking good. About 75 percent of the undergraduates who started with the College in 2010 attained bachelor’s degrees at the University, and more than 50 percent got their degrees in engineering. Every mining engineering undergraduate and 95 percent of civil engineering undergraduates were employed by commencement day 2017! Keeping student enrollment up means being able to invest in new faculty – the key not only to quality education but also to research and invention. The College gained 10 faculty members in fall 2016 and expects another 10 arrivals in fall 2017. Our faculty are studying air flow around vehicles flying at hypersonic speeds and predicting crack propagation in composites. A prestigious Keck Foundation grant is advancing strategies for building quantum computers that may someday replace today’s digital computers. Three projects resulted in technologies acquired by the company MetOxs, which won Tech Launch Arizona’s Startup of the Year Award. One faculty member had 13 invention disclosures and was named TLA’s Inventor of the Year for the physical sciences. Team spirit is high, and we are marching forward. We urge you to visit and celebrate with us. Mark your calendars: Homecoming 2017, October 27-28, is only five months away! Until then… Bear Down!

Remembering Raclare, First Female Tau Beta Pi Profile of early female graduate Raclare Cordis Kanal, BS/ME 1954, marks Women’s History Month

IF THERE IS SUCH a thing as a “Renaissance woman,” it was Raclare Cordis Kanal, who earned her bachelor’s degree in mechanical engineering from the University of Arizona. While raising her family, she immersed herself in many scientific and cultural fields, from genealogy and botany to Mexican mariachi and photography.

In memory of Raclare, who died February 24, 2016, her husband of 55 years, Laveen Kanal, established the Raclare Cordis Kanal Memorial Scholarship Endowment Fund. “I established this fund to inspire Raclare Cordis Kanal engineering students, in particular female students, with Raclare’s example, and to let the UA community learn about her unique life of learning, knowledge sharing and helping others,” said Laveen. Raclare, who has been widely honored for her volunteer work, became the first female member of the UA chapter of Tau Beta Pi engineering honor society in 1953, and was the only woman in her 1954 graduating class.

Governor, Senators, Legislators Honor Mary Poulton State political leaders express their appreciation of the College’s first woman department head upon her retirement.

AT A LUNCHEON in her honor, Mary Poulton was presented with a commendation from Arizona Gov. Doug Ducey, letters of appreciation from U.S. Sens. John McCain and Jeff Flake, proclamations from the Arizona House and Senate, and a certificate of excellence from Arizona State Mine Inspector Joe Hart. “Your contributions to education, mining engineering and support of businesses in these and related fields are greatly appreciated,” the governor’s commendation read in part.

Mary Poulton

Poulton is retiring as University Distinguished Professor in

Geosciences, Mining Engineering, Law and Public Health and director of the Lowell Institute for Mineral Resources, after a 30-year career with the University of Arizona. After earning bachelor’s, master’s and doctoral degrees in geological engineering from the UA, Poulton joined the Department of Mining and Geological Engineering faculty in 1990. She later became department head, quadrupling its enrollment and growing diversity through her dedication to bringing more women and minorities into mining.

Student Seeks a Way to Do Laundry in Space

Senior Christina Morrison is trying to solve a down-to-earth problem for spacetravelers: how to clean their clothes.

ASTRONAUTS’ CLOTHES ADD significant weight to spacecraft, and water is too precious to be used for cleaning clothes, so recent chemical and environmental engineering graduate Christina Morrison is using her NASA Space Grant to find a space-worthy process for waterless laundry. Previous research has shown that silver and hydrogen peroxide, both germ-fighters, become a stronger disinfectant when combined. Morrison and UA professor of microbiology Charles Gerba have for the first time demonstrated this synergistic effect on textiles. They applied hydrogen peroxide to antimicrobial socks embroidered with silver-ion threads and exposed the treated material to Staphylococcus aureus. In one hour, Morrison and Gerba achieved about 99.999 percent reduction of the bacteria on treated antimicrobial socks, versus a 43.76

percent reduction on untreated silverion socks. “In a sense, we were washing the antimicrobial socks in hydrogen peroxide,” Morrison said. The next phase is human testing, with one group wearing antimicrobial socks or regular socks, then removing them for researchers to treat with hydrogen peroxide. A second group will smell the swatches. “We hope it won’t be too hard to find volunteers!” Morrison joked.

Cosmic Cleanup—Christina Morrison works in the lab on methods astronauts can use to clean their clothes.

Janet Roveda Named 2017 da Vinci Fellow

Roveda is honored for multidisciplinary research projects, including largest-ever study on how elementary school students’ sleep habits affect STEM learning.

IN RECOGNITION OF her research contributions, Janet Roveda, professor of electrical and computer engineering and biomedical engineering, has received the 2017 da Vinci Fellowship.

Ahead of Hackers

NEARLY A MILLION NEW forms of malware are unleashed on the world every day. Yet the millions of people with implanted medical devices, or IMDs, typically never receive software upgrades to address security vulnerabilities for the gadgets in their bodies. “It used to be we only had to worry about breaches of our computers and smartphones,” said Roman Lysecky, an associate professor in the Department of Electrical and Computer Engineering. “Industry analysts predict that by 2020 most of the 20 billion electronic devices on the market will be interconnected – and millions of these will be implantable medical devices.” IMDs – cardiac pacemakers and defibrillators, insulin pumps and brain neurostimulators – are connected through the internet or wireless technologies. Many monitor vital signs such as heart rate and transmit data to health care providers in real time. Doctors evaluate patients remotely and, with a few simple adjustments, can improve their conditions and even save lives. But IMDs also pose life-threatening risks. Hackers who gain access to confidential patient information could use malware as “ransomware.” Worse, they could put a pacemaker patient – there are more than 225,000 in the

United States alone – into cardiac arrest. “This hasn’t happened yet to our knowledge,” said Lysecky. “But researchers have proved it is possible.”

“We believe manufacturers should build implantable medical devices like pacemakers with malware detection strategies from the get-go, and provide patches as future problems develop.” ROMAN LYSECKY

Good Timing Lysecky is pioneering technologies to help ensure IMDs will detect malware and keep functioning properly if security is breached. He has built a prototype of a networkconnected pacemaker and is running experiments based on case studies of malware infecting other types of embedded systems. In one project funded by the National Science Foundation, he and co-investigators are developing runtime anomaly detection. This technology exposes minuscule changes in the timing of how computations and data are transmitted from the pacemaker to a cardiac data log, revealing the possibility of malware. A pacemaker might be engineered to send data to a patient’s digital cardiac log every three milliseconds or to send specific types of

encouraging pacemaker manufacturers to regularly monitor, maintain and update software. “We believe manufacturers should build implantable medical devices like pacemakers with malware detection strategies from the get-go, and provide patches as future problems develop,” said Lysecky.

Thwarting Hackers from Every Angle Lysecky is working on yet another project, with a grant from the Army Research Office, to develop mathematical models for analyzing changes in medical implants that make them susceptible to sidechannel attacks.

Lysecky is also looking for malware mimicry, whereby hackers tweak functioning of IMDs in subtle ways to avoid being exposed. His team has achieved a 100-percent detection rate using runtime anomaly detection in the prototype.

Pressure Building for Regulations

Hacker Attacker—PhD student Sixing Lu, who works with Roman Lysecky, holds a prototype network-connected pacemaker, right, that detects hacking of a real pacemaker, left.

Pacemakers are not yet required to have built-in detection and mitigation capabilities, but pressure is building. The U.S. Food and Drug Administration has identified hundreds of medical devices infected by malware and in December 2016 issued security guidelines

“By analyzing data transmission timing, power consumption and electromagnetic radiation from a life-critical device such as a pacemaker, a hacker can extract data like cryptographic keys that are essential for shielding communications from unauthorized users,” he said. 40:1

Design Day’s Palme d’Or—Winners of the Raytheon Award for Best Overall Design display the giant check they received with the award, for designing a drone to pollinate date palms.

A Date to Remember

A drone for pollinating date palms takes top prize at Engineering Design Day 2017.

ART IMITATED LIFE at the University of Arizona’s 15th annual Engineering Design Day on May 1 as more than 500 seniors presented their corporate- and UA-sponsored team projects hatched over nine months. A drone designed to do what bees do best – pollinate – took top prize. In the winning team’s video demonstration the semiautonomous aerial vehicle even sounded like a swarm of bees as it flew over Medjool date palm trees at a nursery in Yuma, Arizona. “Existing drones used to propagate the trees drop pollen from nylon stockings, which is not very efficient,” said systems engineering student Victor Cortez. “Our drone has an automated 45-gram pollen canister that drops a precise payload of pollen over each tree

and can pollinate 12 trees in one flight.” The team is one of several fine-tuning its prototypes for commercialization.

for converting wastewater to drinking water, and a water-efficient technique for manufacturing the arthritis drug Enbrel.

Good Drones, Bad Drones

“Chemical engineering is the art of changing what’s made in the lab to produce a product that’s going to help hundreds of thousands of people,” said senior Erica Clevenger.

Another team won big for Raytheonsponsored technology to take down drones. Commercial drones have video-recording capabilities that can threaten personal privacy, noted systems engineering senior Shivani Patel. Her team’s project would let everyday consumers disable commercial drones autonomously, safely and legally.

New Dimension—A senior demonstrates a 3-D printer, which has become an essential tool for building design project prototypes.

A Crowd Favorite The unpowered exoskeleton, which won an engineering ethics award, was designed to help one person but ultimately could help many more. Initiated by a devoted mother, the project was built to make walking and exercising easier for UA undergraduate Jeffrey Bristol, who has cerebral palsy.

It Takes All Kinds Winning projects also reflected the crossdisciplinary emphasis of the Engineering Design Program, in which seniors from different disciplines spend two semesters working on disparate problems from diverse industries.

Exoskeletal Excellence—Jason Keatseangsilp, front, led his team to win the Frank Broyles Engineering Ethics Award, first prize, for their unpowered exoskeleton.

For example, a Microsoft award went to a project sponsored by GEOST to make it easier for amateur astronomers to transport a telescope to an open area and aim it at a particular part of the sky. And a project sponsored by Ventana Medical Systems for improving tissue imaging won a Thorlabs photonics award.

Thank You, Judges and Mentors! More than 130 professionals volunteered as Design Day judges, and nearly 115 served as technical mentors to the 2017 teams. “Year after year UA Engineering seniors bring a fresh perspective in their approaches and ideas for helping us resolve engineering challenges,” said mentor Mike Szlemko from Raytheon.

The Sound of the Future

AS COMPUTER PARTS grow tinier – billions of transistors are now packed onto silicon chips the size of a fingernail – silicon’s performance shrinks too, and the material can overheat. Engineers are in a race to perfect quantum computers, which store, transmit and process information in fundamentally different ways than their digital cousins and have exponentially greater computing capability.

Deymier has been working with Tech Launch Arizona, the UA’s commercialization arm, to apply for multiple patents surrounding a number of phi-bit inventions, including the quantum computer itself. “We’re excited to work with Pierre Deymier on more patent applications as the Keck Foundation-funded research progresses,” said Bob Sleeper, TLA licensing manager for the College of Engineering.

He is a pioneer in the field of phononics, in which scientists and engineers manipulate phonons, quasiparticles that transmit sound and heat waves in unconventional ways to provide new forms of energy.

The potential of phi-bits to transform computing capability and manage big data appears limitless, Deymier said.

“Phonon-based computing has the power to change the world as we know it,” said Deymier, the department’s head, “not just for making more powerful computers, but for artificial intelligence, cryptography and analysis of big data. For example, a phononic computer could rapidly map a person’s entire genome for developing more targeted medical therapies.”

Introducing the Phi-Bit Pierre Deymier

“I can make phi-bits at room temperature in my lab,” he said.

Pierre Deymier, a University of Arizona professor of materials science and engineering, has received a $900,000 grant from the W.M. Keck Foundation, matched by the UA, for a total of $1.8 million to build a type of quantum computing analogue that might perform as well as existing quantum computers and overcomes problems that plague current quantum computing prototypes.

With his collaborators on the project, professor Pierre Lucas and researcher Keith Runge in the UA Department of Materials Science and Engineering, Deymier will build a prototype phonon-based computer.

He has shown that information can be stored as phi-bits in a superposition state, like qubits, and that multiple phi-bits can be assembled so they cannot be separated – analogous to qubit entanglement. And phi-bits are less sensitive than qubits to external conditions.

ARIZONA ENGINEER

Deymier believes that phonons, in units he has named “phase-bits” or “phi-bits,” are the answer.

“Phonon-based computing has the power to change the world as we know it.” PIERRE DEYMIER

“Let’s suppose you have a million phi-bits, with each one having both a 0 and a 1 in conventional computing bits. That means the amount of information you can process is 2 to the power of 1 million – which may be more than the number of atoms in the universe!” He added, “I believe quantum computing with phononics will be feasible, possibly in the next 10 years.”

Shane Snyder and Agilent Partner on Water Safety and Sustainability

Marla Smith-Nilson Lifts Burden for Communities Lacking Clean Water

Faculty-industry collaboration aims to increase public trust in water reuse.

AGILENT TECHNOLOGIES honored professor of chemical and environmental engineering Shane Snyder with a 2017 Agilent Thought Leader Award, which includes funding plus microarray equipment for Snyder and students working in his lab. With the new equipment, researchers will be able to expand methods for identifying and removing contaminants and further develop technologies for converting wastewater to drinking water.

School of Thought—Shane Snyder, right, receives his thought leader award, presented by, from left, Agilent’s Craig Marvin, Tori Richmond and Leo Brizuela.

“Without question, Agilent equipment has made a meaningful difference in our ability to better characterize environmental quality,” said Snyder.

While interest in recycling municipal wastewater for potable water is growing, many byproducts of the treatment process remain unidentified, Snyder said. “Considering the magnitude of chemical contaminants possible in wastewater, and the nearly infinite number of potential products created during water treatment, the only way forward for comprehensive monitoring is a combined approach of rapid bioassays for evaluating toxicity and advanced, nontargeted analysis for elucidating structure.”

Civil engineering alumna is delivering clean water and expanding opportunities in impoverished countries around the world. MARLA SMITH-NILSON, who received her bachelor’s degree in civil engineering in 1991, founded Water1st International to make water accessible to more than 165,000 people in Bangladesh, India, Ethiopia and Honduras. “We intentionally work in only four countries, so we can really get to know the communities and our partner agencies,” she said. “By supporting local, on-the-ground organizations with a proven track record of implementing water and sanitation projects, we can provide water projects that last.”

Well Engineered—Marla Smith-Nilson delivers a civil engineering Homecoming talk about her work providing sustainable supplies of clean water to thousands in water-stressed regions.

In impoverished countries, millions of women walk for hours every day carrying empty containers to water sources and then walk back home with 40-pound loads. Smith-Nilson accompanied Mari Tuji of Kelecho Gerbi, Ethiopia, one morning as the young mother set out before dawn with her three children on a four-mile trek to reach a small, polluted river. The water always made the children ill, but they had no choice. Working with a local group, Water1st built a new water system in Kelecho Gerbi that Tuji helps to operate.

Jinhong Zhang Invents Concrete Substitute Using Power Plant Waste

Lighter, stronger and less expensive than concrete, Acrete uses three times as much waste and converts it into useful building material.

ASSOCIATE PROFESSOR of mining and geological engineering Jinhong Zhang has developed a new substitute for concrete that has a number of advantages over traditional Portland cement. The new material is lighter, stronger and less expensive to produce than concrete, and uses three times as much fly ash. Coal-fired power plants in the United States produce about 130 million tons of fly ash each year, much of which ends up in mounds and landfills where wind and water can disperse it.

ARIZONA ENGINEER

The new material and the company formed to produce it are called Acrete, a combination of “Arizona” and “concrete.” Zhang says Acrete will “reduce carbon dioxide emissions from cement production and be a novel construction material for a new era of sustainable development.” Tech Launch Arizona, the UA office that commercializes inventions stemming from research, brought together Zhang and entrepreneur Abraham Jalbout to create the startup company to develop the product and bring it to market.

Solid Investment—This UA-created concrete substitute may pave the way to a more sustainable future.
