RICHLAND, Wash. – Four Washington State University professors are pairing up with high school teachers in the Tri-Cities this summer to complete research in viticulture and enology, bioproducts engineering, plant pathology and biological sciences through the MJ Murdock Charitable Trust’s Partners in Science Program.

MJ Murdock Charitable Trust is providing $13,000 to each high school teacher participating, which may go toward research, professional development and other educational resources.  Each team will also receive $2,000 to cover the costs of lab supplies during summer research opportunities in WSU laboratories.

The goal of the program is to bring knowledge from the research lab into the high school science classroom, promoting hands-on science education. The WSU professors will serve as mentors to each of the high school teachers as they complete the research throughout the course of two summers.

Viticulture and enology

WSU Tri-Cities newsThomas Collins, a WSU Tri-Cities assistant professor of viticulture and enology, is working with Frederick Burke, a science teacher at Chiawana High School, to characterize different grape varieties by region, utilizing a process known as gas chromatography/mass spectrometry.

“The process allows us to identify specific chemical profiles in each grape type, which will be used to identify markers associated with the various grape varieties.” Collins said. “The markers will be incorporated into statistical models that would be used to predict the grape varieties used to produce an independent set of Washington state wine samples.”

Biological sciences

WSU Tri-Cities newsElly Sweet, a WSU Tri-Cities clinical assistant professor of biological sciences, and Jim Cooper, a WSU Tri-Cities assistant professor of biological sciences, is working with Amy Verderber, a teacher at Kamiakin High School, to study the impact of thyroid hormone on zebrafish jaw development.

The team is performing development shape analyses of the skull and record and analyze high-speed video footage of fish feeding, in addition to zebrafish husbandry, specimen collection, specimen preparation and photomicroscopy.

“This study is strongly relevant to human health, since there are a large number of human craniofacial disorders associated with alterations of thyroid hormone in blood levels,” Sweet said.

Bioproducts engineering

WSU Tri-Cities newsXiao Zhang, a WSU Tri-Cities associate professor of chemical and bioengineering, is working with Robert Edrington, a science teacher at Southridge High School, to synthesize new functional materials from cellulose, the largest renewable polymer on earth.

Zhang said there is large interest in the application of cellulose nanocrystallites (CNC), which are the elementary units that construct crystalline cellulose from plants.

“My group has previously synthesized a new biocomposite material from CNC for small-diameter replacement vascular graft application,” he said. “The objective of this research is to synthesize new functional materials from CNC.”

Plant pathology

WSU Tri-Cities newsNaidu Rayapati, an associate professor of plant pathology at WSU’s Irrigated Agriculture Research and Extension Center in Prosser, is working with Emily Jordan, a science teacher at Chiawana High School, to study the gene sequencing and genome diversity of economically important grapevine viruses.

“The teacher will gain hands-on experience in molecular biology and state-of-the-art gene sequencing and bioinformatics technologies to elucidate genome diversity of the viruses for practical applications in vineyards,” Rayapati said.

“The experience will help the teacher introduce new concepts of scientific inquiry in the classroom to inspire students interested in pursuing careers in STEM fields,” he said. “We hope to pursue innovative strategies with the K-12 school systems in the Yakima Valley for strengthening higher education in STEM fields.”

Classroom application

The WSU professors are also working with the high school teachers to develop lesson plans, potential course projects and more based in the research they conduct at WSU.

“This partnership will strengthen both the high school program, as well as the research and college science program, by adding a new perspective to the research teach and new tools to use in the classroom,” Cooper said.

Six Washington State University Tri-Cities students sat in a conference room, anxiously waiting for their meeting with a group of AREVA’s engineering and project management officials to begin.

Many of the students didn’t know what to expect, as they had never worked on a project of this magnitude before. This was also their first time at AREVA’s Richland nuclear fuel manufacturing facility.

WSU Tri-Cities newsAs part of their senior mechanical engineering capstone course, the team, which consisted of seniors Jared Beauchene, Jose Chavez, Juan Mejia, Travis Lewis, Alex Schwarz and Manuel Bustos Ramirez, learned they would re-design the AREVA’s current cart used to transport uranium pellets from one building, where they are pressed into shape, to a different building, where they are sintered at a high temperature into their final form.

AREVA Plant Operations Manager Barry Tilden said the problems with the facility’s current pellet transfer cart is that it poses several safety concerns. There are several potential finger pinch points and ergonomic challenges posed when loading the small but heavy trays of uranium pellets, also known as “boats,” he said.

In addition to overcoming those safety elements, the new cart design would have to ensure a safe transport of the delicate pellets before sintering and contain the pellets if it were to tip over during transport. The cart would also have to provide protection from weather during the short trip from building to building and interface well with the existing equipment in two separate pellet production shops.WSU Tri-Cities news

The team spent the next seven months on the new design, balancing their time on the project with a full course load at WSU Tri-Cities.

“It’s was difficult,” Chavez said. “We knew this project would come with expectations and responsibilities. But as we worked through the design challenges, the project has been very rewarding and has given us great experience as we start looking for jobs after graduation.”

Tilden said the team truly embraced the challenges of the design while working through many obstacles and business requirements.

“The team did a great job and can be proud of their work developing and producing a new pellet cart design,” he said.

The team documented their progress through a series of posts on AREVA’s blog site. The entries provide insights into the different stages of the project and the struggles the team overcame along the way.

RICHLAND, Wash. – Four Washington State University Tri-Cities students are working with AREVA, a multinational group specializing in nuclear power and renewable energy, to identify real-world process and cost improvements for the company using the Six Sigma approach.

The effort is part of WSU Tri-Cities’ master’s in business administration capstone course, which is led by Tim Baker, associate professor of finance and management science.

“Through student-led projects, we either implement process improvements or new product designs and measure the benefits of each,” Baker said of the Six Sigma process. “It’s all about maintaining a continuous improvement in methodology.”

MBA students John Kummer, Kevin Sykes, Hongfei Rassmussen and Sammy Ernst are currently examining the processes and organizational structure within AREVA to identify cost and process improvements for production supplies.

Baker, who holds the highest certification in the Six Sigma process – a master black belt, said WSU Tri-Cities has paired up with local organizations for the last eight years to complete similar projects, and that AREVA has been a primary customer since day one. The student projects, he said, has saved various local organizations significant time and money.

Baker said on one previous year’s project, the students worked out a procedure to save the Sandvik Specialty Metals company approximately $750,000 due to a 25 percent reduction in throughput variability in the pilgering process for their titanium rods production. Another student project reduced the average patient flow time for the Grace Medical Clinic by 17 percent.

This year’s student group hopes for similar results in their own project with AREVA.

What is Six Sigma?

 Baker said the purpose and goal with the Six Sigma process is to systematically assess the current state of a process, uncover and prioritize improvement and design goals and generate and prioritize ideas for improvements and designs.

Six Sigma professionals measure the benefits to the client for an implementation of an improved process or new design and set up a control plan for the client to ensure that performance does not regress once the Six Sigma project has been disbanded.

Paul Skilton, assistant professor of management, information systems and entrepreneurship, said one of the great aspects of the project and utilizing the Six Sigma approach in a real-world scenario is that the students actively see all the “worms” and the “mess” of systematic procedure within companies, which is also not unique to any one company.

“They’re working through organizational messes that end up generating real results,” he said. “They are able to work through what we call a wicked problem. It’s a problem that doesn’t appear to have nice answers, but they ultimately have to get to one.”

Value to the company and the student

For AREVA, getting students involved in the company’s process and procedures opens opportunities to evaluate both new and old strategies.

“Projects like these give us a fresh perspective on our own processes and identify previously unseen improvement opportunities,” said Lance Stephens, AREVA manager of operations strategy and supply chain.

Ernst said part of her job outside of school is recognizing a problem within her company, examining the root of that problem and determining a solution. Utilizing the Six Sigma process through a real-world scenario in her MBA class, she said, is instrumental both in her academic and professional life.

“My employer is currently trying to ramp up in Six Sigma and improve its processes,” she said. “There is a huge push towards Six Sigma in our career fields, so this is definitely a huge asset.”

Sykes said it has been rewarding seeing the “mess” of the internal company structure because it is useful in his own career.

“It’s real-world life experience and we get do dive into a project in a company and see the overall scope,” Sykes said. “It’s been a really good learning experience.”

Skilton said WSU Tri-Cities also benefit from having Baker as their professor and mentor, as he is a world-class Six Sigma and operations research expert.

“As a result of his knowledge and experience in the field, our students here locally get to work on these exceptional projects,” he said.

RICHLAND, Wash. – Ma Thu Sha La was an infant in 1982 when his family left his home country of Burma, fleeing what quickly became a war zone.

“Soldiers came into the village and we couldn’t live there anymore,” he said through a translator. “They started killing people. We were scared we might be next. Everyone left.”

As refugees in Papu, Thailand, his family shared a one-bedroom bamboo hut alongside thousands of others. They struggled for low-paying jobs in road construction and WSU Tri-Cities newsweren’t allowed to seek employment outside the camp. Ma Thu said sometimes, despite hours of grueling road work, they would not see a paycheck for their efforts.

“It was hard,” he said. “But the worst part was the waiting. We lived in the dark, not knowing what was going on.”

In 2011, after years in the refugee camp, Ma Thu and his wife, Lu Dee, whom he married in 2003, received word they would be coming to the United States after applying and being approved for their green cards.

Once in the U.S., they aspired to own their own home, but they didn’t know if the feat was possible. In their first few years in the U.S., the family shared a two-bedroom apartment in Pasco, Wash., on Ma Thu’s salary of $25,000.

WSU Tri-Cities newsLast year, the family was approved for a three-bedroom, 1,200 square feet house after applying through the Tri-County Partners Habitat for Humanity. Sponsored and built in partnership with Washington State University Tri-Cities, the home is one of 24 themed houses sponsored by various local organizations as part of Habitat’s Whitehouse Addition Project in Pasco.

To make their home a reality, WSU Tri-Cities must raise approximately $80,000 to supplement the building and enable Habitat to sell it to the family at an affordable price with no-interest loans. The family is required to dedicate 500 sweat equity hours to construction.

Donations may be made to the program by contacting Ken Fincher, WSU Tri-Cities assistant vice chancellor of advancement and community engagement, at ken.fincher@tricity.wsu.eduor 509-372-7398.WSU Tri-Cities news

“This is an opportunity to provide for a family that has lived a life unimaginable to many,” Fincher said. “For years, this family dreamed of a home. This is our chance to give them one. Any donation will go directly into this project.”

Manny-Garcia-80RICHLAND, Wash. – Within the confines of his cold, concrete prison cell, Emmanuel “Manny” Garcia found himself seven years ago contemplating the depths of his reality.

Following the death of his father in 2000, he got involved with the wrong crowd and started abusing drugs. In 2009, he was found guilty of theft of firearms and burglary and began serving a sentence at Airway Heights Corrections Center in Spokane, Wash.

There, he started a plan to ensure he would never see the inside of a prison cell again: “I enrolled in some college classes,” he said.

Thanks to this first step, and help from the federal TRIO program, he has overcome his criminal past and is thriving as a student speaker and future leader. TRIO provides low-income, first-generation and disabled students with tutoring, counseling and other resources to help them succeed both inside and outside the classroom.

“TRIO changed my life,” Garcia said. “I don’t know where I would be today without the TRIO program and the help I’ve received through Washington State University Tri-Cities.”

Care, concern keep him on track

While taking courses in prison through Spokane Falls Community College, Garcia worked with his chemical dependency counselor to end the toxic cycle of substance abuse and addiction. He got a job, earning 30 cents an hour, to pay off $1,500 in college debt he owed from a previous try at community college.

WSU Tri-Cities student Emmanuel “Manny” Garcia is using the university TRIO program to overcome his troubled past and help others.

“I was battling many personal issues and many personal demons,” he said. “I wanted a better life for myself. I knew it could be done through the power of education.”

Out of prison in March 2012, he enrolled in Big Bend Community College. After a successful first quarter, he decided to take winter quarter off.

“I was just feeling that I wasn’t adequate and I wasn’t worthy to go back and be in school,” he said. “My thought was ‘How is a convict like me ever going to change?’ That was when a TRIO advisor called me. They cared enough to call and see if I was OK.”

That gave him the motivation to complete his associate’s degree before enrolling at WSU Tri-Cities, where TRIO has continued to be crucial to his success.

Better future based on education, experience

A junior psychology student, Garcia ultimately hopes to earn a doctorate and start a nonprofit organization to help out others with troubled pasts.

He said the TRIO staff at WSU Tri-Cities has been able to locate scholarships for him that he would not have known about otherwise. He is on a psychology research team and participates in community service projects. He holds a 3.8 grade point average.

He has served as a resident advisor for TRIO Upward Bound, the organization’s summer academy program, where he shares his story with younger students.

“Things are going really well for me now, and I owe a lot of that to the TRIO program,” he said.

He works with the El Nuevo Camino organization, a crisis intervention program to reduce youth crime and violence. He serves on the board and is being trained to become project manager.

“It is a new organization, but we collaborate with local law enforcement, judges, district attorneys, community leaders and health professionals,” he said. “Our plan is to make a real difference right here in our local community.”

Aiming for grad school, inspiring others

Garcia said he hopes his story encourages others on the path to success and will motivate others to apply to TRIO and get involved.

He recently spoke at WSU Tri-Cities’ first celebration of National TRIO Day:

“I want to encourage you, if you are a first-generation, low-income or disabled student, to sign up for TRIO today,” he said. “I am fully convinced that TRIO works. I am living proof. If I can do it, so can you.”

He plans to apply for TRIO’s Ronald E. McNair Postbaccalaureate Achievement Program, which is a competitive grant for graduate school for participants from disadvantaged backgrounds who have demonstrated strong academic potential.

RICHLAND, Wash. – Cameron Hohimer, a Washington State University Tri-Cities mechanical engineering doctoral student, will explore the possibilities of soft robotics through 3-D printing as part of a National Science Foundation Graduate Research Fellowship.

Hohimer was awarded a $34,000 for three-years annual stipend and an additional $12,000 for three years education allowance, which will offset the cost of tuition and fees.

Hohimer had a small part in working on the apple picking robot that WSU researchers Manoj Karkee and Changki Mo are constructing with the help of graduate researchers. He said that robot, for example, has rigid links that allow it to grab the apples at certain pressure points for certain sizes and shapes. But with soft robotics, they could attempt to create more compliant actuators, which are responsible for moving or controlling a system, using more malleable materials, he said.

Cameron Hohimer“Soft robotics is a relatively new area of study in which we are trying to create non-rigid actuators and components for robotics systems,” he said. “The nice thing is if you were to use something like this for apple harvesting, as you move into objects, it is compliant. It would bend out of the way. It can more easily form to what it is you are trying to do.”

Hohimer said current methods for creating many of these types of soft robotics materials are done through injection molding and silicon casting, but his hope is that he can use fused deposition modeling, a type of 3-D printing, to make the fabrication process faster and easier, as well as utilize it to create parts and products that are more complex in design.

“You see a lot of applications of soft robotics in creating humanoid robots,” he said. “Obviously our hands are very dexterous. You can pick up a wide range of objects with varying geometries and sizes. Most rigid grabbers, or end effectors, are not good at picking up cylindrical objects and then trying to pick up something that is a different shape. With soft robotics, you can design manipulators that are more robust that can grasp items with a wide variety of shapes and sizes.”

With his research, Hohimer will also investigate the ability to 3-D print piezoelectric polymers, which could be used to sense strain and vibration and be embedded into soft robotic actuators.

Hohimer earned his bachelor’s in mechanical engineering from WSU Tri-Cities in 2014. He is two years into his doctoral program in mechanical engineering at WSU Tri-Cities.

MarceauRICHLAND, Wash. – Students got to dig deep in a Washington State University Tri-Cities class recently, exploring archaeology while uncovering authentic materials provided by local Native Americans.

Professor Thomas Marceau spent 44 years as a professional archaeologist – 22 at the Hanford site. Through relationships formed there with the Wanapum people, he borrowed authentic artifacts, bones and other materials to bury in test boxes that students excavated and analyzed.

“We’ve spent the past few months going over the procedures archaeologists use in the excavation process,” he said of the new Introduction to Archaeology course. “I wanted to provide students the chance to try out everything they’ve learned on an actual dig.

“I thought it was important to have authentic tools for this,” he said. “Students get experience identifying real artifacts and materials.”

In addition to the artifacts provided by local Native Americans, the soil, excavation tools a


Professor Thomas Marceau, center, talks with students excavating five test boxes planted with authentic artifacts provided by the Wanapum Native Americans.

nd other materials were as close to real-world examples as possible.

“The sand we’re using in the test units is dry and dusty, mimicking the Hanford site in July and August,” Marceau said. “It’s hard to excavate. Students used trowels and brushes as their primary excavation tools as they do in the real-world setting.

“Each site has a different activity showing how Native American people made their living,” he said. For example, one of the test boxes held artifacts that might be left behind by an ancient woman grinding bones to get grease and marrow to eat and use. Others held remnants that would remain from a butchering station and a hide processing area.

Once the students excavated and documented their finds, they measured and identified them in the lab. They are writing excavation reports about their discoveries and the general archaeology process.

Most of the students said they enjoyed the real-world exploration provided by the course.

“It lets you experience what it would be like if you were actually doing an excavation,” said Michelle Meehan, a senior business student.

“It’s interesting uncovering history through items we find,” said Christian Rochon, a senior history student. “A lot of history is written by archaeology. It’s cool learning where we were back then and how we got to where we are now.”

RICHLAND, Wash. – Researchers at Washington State University Tri-Cities have figured out a way to successfully convert a common wood byproduct into hydrocarbon molecules that could be used as jet fuel.

Bin Yang, an associate professor of biological systems engineering, said the hydrocarbons from his new procedure could eventually replace the need for petroleum-based fuel sources.

The work of Yang’s team will be on the cover of the December issue of Green Chemistry, a journal of the Royal Society of Chemistry. The work was published online in September and can be seen at
Yang also holds a patent on the process:

Making use of lignin waste

Yang’s procedure converts lignin, an organic polymer that makes plants woody and rigid. Ordinarily, it is wasted when plant biomass, including cellulose, is converted into biofuels like ethanol.

“After cellulose, it is the most abundant renewable carbon source on Earth,” according to the website of the Switzerland-based International Lignin Institute. Between 40 and 50 million tons of lignin are produced annually worldwide, mostly as a non-commercialized waste product, according to the institute.

“The effort to transform lignin into higher-value products for large developed markets is critically needed,” Yang said. “If we can make jet fuel from the biomass-derived lignin, it addresses this challenge.”

Yang said the process could grow the economic potential of advanced biofuels.

“It will begin to address the nation’s challenge for the production of clean, domestic biofuels that can help replace crude oil,” he said.

Biofuel partnership with Boeing

Yang’s team is working with Boeing Co. to develop and test the hydrocarbons targeted to be jet fuel.

Yang’s procedure converts lignin into a mix of hydrocarbons in a single reactor using appropriate catalysts. The resulting product must be separated and purified to obtain the jet-fuel hydrocarbons that can be used in turbine engines.
Ralph Cavalieri, director of WSU’s Office of Alternative Energy, said molecules derived from biomass currently must be combined with petroleum-based jet fuel to meet the certification requirements for jet fuel. Yang’s procedure, however, may be able to supply the molecules that are necessary to be certified as a jet fuel.

Jet fuel typically needs molecules that consist of 12 to 16 carbon atoms to fulfill jet engine requirements, Cavalieri said. Comparatively, gasoline requires molecules with fewer carbon atoms, but that fuel is much more volatile. On the other end of the spectrum is diesel, which requires molecules of 16 to 20 or more carbon atoms. While it is significantly less volatile, diesel begins to gel at cold temperatures.

Cavalieri said jet fuel requires the same nominal range of molecules as kerosene, which isn’t as volatile as gasoline but also doesn’t freeze at the cold temperatures found at altitude.

“With the research being conducted by Dr. Yang, it may be possible to develop a more complete suite of molecules required for turbine engine systems using only biomass feedstocks, making the process more economically feasible and efficient,” he said.

Lignin yields diverse bioproducts

In addition to hydrocarbons suitable for jet turbine engines, Yang is using lignin to produce a variety of other chemicals and materials. Through two recent grants funded by the U.S. Department of Energy, both headed by Texas A&M University, he leads WSU’s effort to produce lipids and bioplastics created from lignin.

He also is working with the nearby Pacific Northwest National Laboratory and the National Renewable Energy Laboratory in Colorado on projects to convert lignin into a range of chemicals, including supercapacitors.

Yang and his team’s research is supported by the Defense Advanced Research Projects Agency through the U.S. Department of Defense, as well as the U.S. Department of Energy, the National Science Foundation, the Sun Grant from the U.S. Department of Transportation, the National Renewable Energy Laboratory and the Seattle-based Joint Center for Aerospace Technology Innovation.

RICHLAND, Wash. – Sebastian Fernandez has learned lessons about teamwork, the “art” of experiential learning and the rewards of rigorous study as an undergraduate at Washington State University Tri-Cities. He hopes to apply and expand those skills in the first class of WSU’s new medical school in Spokane, Wash.

“It sounds cheesy, but I just want to help people,” he said. “I could do that by becoming a doctor. I knew WSU could help me get there.”

Practical beginnings

A competitive WSU summer internship at Kadlec Regional Medical Center exposed him to the medical field via real-world application.

In one instance, a man stopped breathing and, within seconds, the doctor and his team worked efficiently to restore the man’s breathing.

“In 30 seconds, they brought him back from the dead,” Fernandez said. “It was amazing.”

Fernandez said that doctor gave him advice that he will use in his career as a physician.

“He told me, ‘The most important thing you have to remember is team work. Just because you’re a doctor doesn’t mean you get to boss everybody around,’ ” he said. “That stuck with me. It takes a team to accomplish great things.”

Research experience

SebastianFernandez-1-webSo Fernandez teamed with Birgitte Ahring, professor in the Bioproducts, Sciences and Engineering Laboratory at WSU Tri-Cities, to create a more efficient biofuel using volatile fatty acids from cow stomach fluid and corn stover (post-harvest waste) in the absence of oxygen, also called anaerobic fermentation.

“We wanted to pick an area that would be relevant to the medical field and apply to his future aspirations,” Ahring said. “Anaerobic bacteria is relevant for humans because the inside of humans is anaerobic and the human body houses 10 times more bacteria than human cells.”

Cow stomach fluid was added to corn stover to produce volatile fatty acids, which can be used to produce biofuel to power cars, planes and other vehicles.

“School is typically very structured,” Fernandez said. “You follow the steps and write down what you observe. In a more experimental setting, it is kind of like working with a blank canvas. It is like an art. You can do anything. You can test anything.”

Rigors and rewards

“It took me months to learn,” he said of the research. “I had no idea I would have my own experiments and be writing a scientific paper with references. It is really hard. It takes hundreds of hours.”

But it provided him with experience needed for entering into the medical field, he said, while allowing him to conduct research that will make a difference in the biofuels industry some day.

“I just want to make a difference and the best way to do that is by helping others,” he said.
He said his results show that untreated corn stover actually yields greater volatile fatty acid production than pretreated corn stover. This finding will save the industry in the long run because the material won’t require pretreating.

He is making the final touches on a research paper, which he will work on with Ahring to send in for publication.

Medical school and beyond

After completing his undergraduate work this summer, Fernandez plans to take the medical school admission test and apply to schools in the fall.

“I want to go into immunology and infectious disease,” he said. “I feel like I have a good mind and can figure things out. The best way to help the world is by using those skills in the medical field.”

He eventually intends to work in a free clinic so he can give back to the community.

He said he would love to be one of the first graduates of WSU’s new medical school, which plans to welcome its first students in fall 2017.
