OSU named a “top green school” by Princeton Review

CORVALLIS, Ore. – Oregon State University was ranked number 38 of “50 Top Green Schools” in the 2015 edition of The Princeton Review Guide to 353 Green Colleges.

The guide profiles colleges with exceptional commitments to sustainability, based on their academic offerings and career preparation for students, campus policies, initiatives, and activities. It also gives college applicants information about each school's admission requirements, cost and financial aid, as well as student body facts and statistics.

OSU received a green rating score of 98, and was recognized for its formal sustainability committee, available transportation alternatives and the availability of sustainability-focused degrees, among other things. The highest score a college can receive is 99.

The company tallied 861 colleges in summer 2014, using data from its 2013-14 survey of school administrators. The survey asked them to report on their school's sustainability-related policies, practices, and programs. 

The guide is available online at http://bit.ly/1DQ8te0 and is the only free comprehensive resource of its kind.

According to the review, students at OSU enjoy an "exceptional 'green living' education" on campus. Even the exercise machines at the recreation center help power the university's electrical grid. Known for its excellent reputation in sustainability, many students are drawn to OSU's outstanding engineering, forestry, biology, and geoscience programs. 

“OSU continues to be recognized for going above and beyond in its efforts to create a sustainable campus and a well-rounded student experience that increases awareness of critical global issues,” said Brandon Trelstad, OSU’s sustainability coordinator. “It’s great to be consistently recognized by the Princeton Review and other organizations, and it encourages us to keep meeting higher goals for our sustainability efforts.”

OSU receives Gold designation for sustainability

CORVALLIS, Ore. – Oregon State University has again received a “Gold” designation from the Sustainability Tracking, Assessment and Rating System, or STARS, the second highest rating a university can receive.  Platinum is the highest rating, but no university received that designation this year.

STARS is administered by the Association for the Advancement of Sustainability in Higher Education, of which OSU is a member. Schools are rated in four large categories of academics; engagement; operations, planning and administration; and one additional innovation category.

“This repeated Gold designation is a great indicator of the comprehensive and consistent nature of OSU’s sustainability work,” said Brandon Trelstad, OSU’s sustainability coordinator.

“It’s a team effort that includes entities beyond the Sustainability Office, like Campus Recycling and the Student Sustainability Initiative,” Trelstad said. “We have established solid programs but are always looking for ways to expand positive impact and demonstrate leadership.”

OSU was the first Oregon university to be rated by STARS, and received a Gold designation in 2011, and again in 2013.

This year, OSU received high marks for its sustainability coordination and planning, its diversity and affordability, and a perfect score on campus engagement. It also earned high marks for academic research, including support and access.

President Edward Ray said that STARS provided a guidepost in helping the university develop programs and initiatives around sustainability.

"The assessment is a valuable tool in forging new conversations and inspiring actions around issues of global importance, like biodiversity, climate change, divestment and social justice," Ray wrote in his submittal letter to the STARS Steering Committee.

Of other participating Oregon institutions, only Portland State University received a Gold designation. Pacific University and Oregon Institute of Technology received “Bronze” designations, and University of Oregon’s designation was “Reporter.”

solar Solar panel array at Oregon State University

Technology using microwave heating may impact electronics manufacture

The study this story is based on is available online: http://bit.ly/1pJjhnK

 

CORVALLIS, Ore. – Engineers at Oregon State University have successfully shown that a continuous flow reactor can produce high-quality nanoparticles by using microwave-assisted heating – essentially the same forces that heat up leftover food with such efficiency.

Instead of warming up yesterday’s pizza, however, this concept may provide a technological revolution.

It could change everything from the production of cell phones and televisions to counterfeit-proof money, improved solar energy systems or quick identification of troops in combat.

The findings, recently published in Materials Letters, are essentially a “proof of concept” that a new type of nanoparticle production system should actually work at a commercial level.

“This might be the big step that takes continuous flow reactors to large-scale manufacturing,” said Greg Herman, an associate professor and chemical engineer in the OSU College of Engineering. “We’re all pretty excited about the opportunities that this new technology will enable.”

Nanoparticles are extraordinarily small particles at the forefront of advances in many biomedical, optical and electronic fields, but precise control of their formation is needed and “hot injection” or other existing synthetic approaches are slow, costly, sometimes toxic and often wasteful.

A “continuous flow” system, by contrast, is like a chemical reactor that moves constantly along. It can be fast, cheap, more energy-efficient, and offer lower manufacturing cost. However, heating is necessary in one part of the process, and in the past that was best done only in small reactors.

The new research has proven that microwave heating can be done in larger systems at high speeds. And by varying the microwave power, it can precisely control nucleation temperature and the resulting size and shape of particles.

“For the applications we have in mind, the control of particle uniformity and size is crucial, and we are also able to reduce material waste,” Herman said. “Combining continuous flow with microwave heating could give us the best of both worlds – large, fast reactors with perfectly controlled particle size.”

The researchers said this should both save money and create technologies that work better. Improved LED lighting is one possibility, as well as better TVs with more accurate colors. Wider use of solid state lighting might cut power use for lighting by nearly 50 percent nationally. Cell phones and other portable electronic devices could use less power and last longer on a charge.

The technology also lends itself well to creation of better “taggants,” or compounds with specific infrared emissions that can be used for precise, instant identification – whether of a counterfeit $20 bill or an enemy tank in combat that lacks the proper coding.

In this study, researchers worked with lead selenide nanoparticles, which are particularly good for the taggant technologies. Other materials can be synthesized using this reactor for different applications, including copper zinc tin sulfide and copper indium diselenide for solar cells.

New Oregon jobs and businesses are already evolving from this work.

OSU researchers have applied for a patent on aspects of this technology, and are working with private industry on various applications. Shoei Electronic Materials, one of the collaborators, is pursuing “quantum dot” systems based on this approach, and recently opened new manufacturing facilities in Eugene, Ore., to use this synthetic approach for quantum dot enabled televisions, smartphones and other devices.

The research has been supported by the Air Force Research Laboratory, OSU Venture Funds, and the Oregon Nanoscience and Microtechnologies Institute, or ONAMI.

OSU solar projects provide cost savings, reduce carbon emissions

CORVALLIS, Ore. – Oregon State University this spring has brought the largest of its ground-mounted solar arrays online as part of the Oregon University System’s “Solar by Degrees” program.

The university now has three solar project sites in Corvallis covering some 10 acres collectively that have the capacity to generate more than 2.6 million kilowatt-hours of power per year. The system not only provides cost savings by providing solar energy for less than current utility power rates, it helps Oregon State reduce its carbon footprint in a way that doesn’t cost the university money up front.

The arrays were constructed and are owned and operated by SolarCity, which has worked with OSU and the Oregon Institute of Technology for several years on the Solar by Degrees programs. The company’s collaboration with OSU has not been limited to the Corvallis campus, according to Brandon Trelstad, the university’s sustainability coordinator.

“The way the partnership works is that SolarCity installs the solar arrays at no cost to the university, and OSU simply pays for solar energy that they produce – at a lower rate than they would pay for utility power,” Trelstad said.

This past fall, SolarCity completed a 431-kilowatt installation at OSU’s Hermiston Agricultural Research and Experiment Station in Eastern Oregon, and another 221-kilowatt solar project at the North Willamette Research and Extension Center in Aurora. Annual electrical output from all five OSU solar sites is approximately equivalent to the annual carbon emissions from 255,025 gallons of gasoline or 477 passenger vehicles, according to US Environmental Protection Agency’s Greenhouse Gas Equivalencies Calculator.

“This is another step toward meeting OSU’s aggressive carbon emissions reduction targets,” Trelstad said. “It also saves the university money and provides some unique research and educational opportunities. Advancements like Solar by Degrees don’t come along often and I’m glad that OSU has been able to maximize our use of the groundwork laid by the Oregon University System.”

Two of the sites in Corvallis have operated for more than a year, but the latest site in Corvallis - which is located near 35th Street and Campus Way – just went online. Each installation is “grid-tied,” which means it seamlessly provides power when the sun shines and blends in utility power when it doesn’t.

At the branch Experiment Stations, the arrays not only save money, they provide an example of how solar power can work in a rural and/or agricultural setting.

“The solar array at Hermiston is expected to reduce our electricity costs by about half – a savings of about $30,000 in the first year and could increase in the future depending on electricity costs,” said Philip B. Hamm, director of the Hermiston Agricultural Research and Experiment Station.

“This allows us to provide more financial support toward our mission, which is to provide new research-based information to clients.”

Michael Bondi, director of the North Willamette Research and Extension Center located just south of Wilsonville, said the center at the end of February received its first electrical utility bill since the project was launched.

“For that month, we reduced our cost from the previous year by 50 percent,” Bondi said. “I like how that looks, especially in the middle of winter and a lot of gray days. Based on the design specs for the project, we expect to reduce our electrical usage from the grid by 80 to 85 percent each year.

“I’d say we are well on the way to that goal.”

“This will likely be the largest scale installations we complete here,” said Trelstad. “However, over the next few years, we will look for additional opportunities to install solar panels on roofs since we already have used much of the compatible ground space.”

At two of the three Corvallis installations, the College of Agricultural Sciences is grazing sheep next to the solar arrays, which is how the land previously was used. “This is a great way to optimize land use and not consume productive ground solely with solar installations,” Trelstad noted.  At the Aurora location, a bee and insect pollinator habitat area is being planned. At the Hermiston location, the area had never been used for research given its irregular shape and lack of water availability, but now benefits the campus to provide solar power in an otherwise unusable space.

OSU scientists part of national APLU report outlining research challenges

CORVALLIS, Ore. – The national Association of Public and Land-grant Universities released a report today outlining six “grand challenges” facing the United States over the next decade in the areas of sustainability water, climate change, agriculture, energy and education.

The APLU project was co-chaired by W. Daniel Edge, head of the Department of Fisheries and Wildlife at Oregon State University. The report is available online at: http://bit.ly/1ksH2ud

The “Science, Education, and Outreach Roadmap for Natural Resources” is the first comprehensive, nationwide report on research, education and outreach needs for natural resources the country’s university community has ever attempted, Edge said.

“The report identifies critical natural resources issues that interdisciplinary research programs need to focus on over the next 5-10 years in order to address emerging challenges,” Edge noted. “We hope that policy-makers and federal agencies will adopt recommendations in the roadmap when developing near-term research priorities and strategies.”

The six grand challenges addressed in the report are: 

  • Sustainability: The need to conserve and manage natural landscapes and maintain environmental quality while optimizing renewable resource productivity to meet increasing human demands for natural resources, particularly with respect to increasing water, food, and energy demands.
  • Water: The need to restore, protect and conserve watersheds for biodiversity, water resources, pollution reduction and water security.
  • Climate Change: The need to understand the impacts of climate change on our environment, including such aspects as disease transmission, air quality, water supply, ecosystems, fire, species survival, and pest risk. Further, a comprehensive strategy is needed for managing natural resources to adapt to climate change.
  • Agriculture: The need to develop a sustainable, profitable, and environmentally responsible agriculture industry.
  • Energy: The need to identify new and alternative renewable energy sources and improve the efficiency of existing renewable resource-based energy to meet increasing energy demands while reducing the ecological footprint of energy production and consumption.
  • Education: The need to maintain and strengthen natural resources education at our schools at all levels in order to have the informed citizenry, civic leaders, and practicing professionals needed to sustain the natural resources of the United States.

 

Three other OSU researchers were co-authors on the report, including Hal Salwasser, a professor and former dean of the College of Forestry; JunJie Wu, the Emery N. Castle Endowed Chair in Resource and Rural Economics; and George Boehlert, former director of OSU’s Hatfield Marine Science Center.

Wu played a key role in the climate change chapter in identifying the need to better understand the tradeoffs between investing now in climate change adaptation measures versus the long-term risk of not adopting new policies.

Edge and Boehlert contributed to the energy chapter, which focuses primarily on renewable energy.

“The natural resources issues with traditional sources of energy already are well-understood,” Boehlert said, “with the possible exception of fracking. As the country moves more into renewable energy areas, there are many more uncertainties with respect to natural resources that need to be understood and addressed. There are no energy sources that do not have some environmental issues.”

Salwasser was an author on the sustainability chapter that identifies many issues associated with natural resource use, including rangelands, forestry, fisheries and wildlife and biodiversity. The authors contend the challenge is to use these resources in a sustainable manner meeting both human and ecosystem needs.

The project was sponsored by a grant from the U.S. Department of Agriculture to Oregon State University, which partnered with APLU and authors from numerous institutions.

Amber fossil reveals ancient reproduction in flowering plants

CORVALLIS, Ore. – A 100-million-year old piece of amber has been discovered which reveals the oldest evidence of sexual reproduction in a flowering plant – a cluster of 18 tiny flowers from the Cretaceous Period – with one of them in the process of making some new seeds for the next generation.

The perfectly-preserved scene, in a plant now extinct, is part of a portrait created in the mid-Cretaceous when flowering plants were changing the face of the Earth forever, adding beauty, biodiversity and food. It appears identical to the reproduction process that “angiosperms,” or flowering plants still use today.

Researchers from Oregon State University and Germany published their findings on the fossils in the Journal of the Botanical Institute of Texas.

The flowers themselves are in remarkable condition, as are many such plants and insects preserved for all time in amber. The flowing tree sap covered the specimens and then began the long process of turning into a fossilized, semi-precious gem. The flower cluster is one of the most complete ever found in amber and appeared at a time when many of the flowering plants were still quite small.

Even more remarkable is the microscopic image of pollen tubes growing out of two grains of pollen and penetrating the flower’s stigma, the receptive part of the female reproductive system. This sets the stage for fertilization of the egg and would begin the process of seed formation – had the reproductive act been completed.

“In Cretaceous flowers we’ve never before seen a fossil that shows the pollen tube actually entering the stigma,” said George Poinar, Jr., a professor emeritus in the Department of Integrative Biology at the OSU College of Science. “This is the beauty of amber fossils. They are preserved so rapidly after entering the resin that structures such as pollen grains and tubes can be detected with a microscope.”

The pollen of these flowers appeared to be sticky, Poinar said, suggesting it was carried by a pollinating insect, and adding further insights into the biodiversity and biology of life in this distant era. At that time much of the plant life was composed of conifers, ferns, mosses, and cycads.  During the Cretaceous, new lineages of mammals and birds were beginning to appear, along with the flowering plants. But dinosaurs still dominated the Earth.

“The evolution of flowering plants caused an enormous change in the biodiversity of life on Earth, especially in the tropics and subtropics,” Poinar said.

“New associations between these small flowering plants and various types of insects and other animal life resulted in the successful distribution and evolution of these plants through most of the world today,” he said. “It’s interesting that the mechanisms for reproduction that are still with us today had already been established some 100 million years ago.”

The fossils were discovered from amber mines in the Hukawng Valley of Myanmar, previously known as Burma. The newly-described genus and species of flower was named Micropetasos burmensis.

OSU spinoff company NuScale to receive up to $226 million to advance nuclear energy

CORVALLIS, Ore. – A promising new form of nuclear power that evolved in part from research more than a decade ago at Oregon State University today received a significant boost: up to $226 million in funding to NuScale Power from the United States Department of Energy.

NuScale began as a spinoff company based on the pioneering research of OSU professor Jose Reyes, and since has become one of the international leaders in the creation of small “modular” nuclear reactors.

This technology holds enormous promise for developing nuclear power with small reactors that can minimize investment costs, improve safety, be grouped as needed for power demands and produce energy without greenhouse gas emissions. The technology also provides opportunities for OSU nuclear engineering students who are learning about these newest concepts in nuclear power.

“This is a wonderful reflection of the value that OSU faculty can bring to our global economy,” said Rick Spinrad, vice president for research at OSU. “The research conducted by Professor Reyes, colleagues and students at OSU has been a fundamental component of the innovation at NuScale.”

NuScale has continued to grow and create jobs in Oregon, and is bringing closer to reality a nuclear concept that could revolutionize nuclear energy. The Obama administration has cited nuclear power as one part of its blueprint to rebuild the American economy while helping to address important environmental issues.

In the early 2000s at OSU, Reyes envisioned a nuclear power reactor that could be manufactured in a factory, be transported to wherever it was needed, grouped as necessary to provide the desired amount of power, and provide another option for nuclear energy. It also would incorporate “passive safety” concepts studied at OSU in the 1990s that are already being used in nuclear power plant construction around the world. The design allows the reactor to shut down automatically, if necessary, using natural forces including gravity and convection.

The Department of Energy announcement represents a milestone in OSU’s increasing commitment to university and business partnerships and its goals of using academic research discoveries to promote new industries, jobs, economic growth, environmental protection and public health.

“OSU has made a strong effort to build powerful partnerships between our research enterprise and the private sector,” said OSU President Edward J. Ray. “The DOE support for NuScale is a vote of confidence in the strategy of building these meaningful relationships, and they are only going to pick up speed with our newest initiative, the OSU Advantage.”

The Oregon State University Advantage connects business with faculty expertise, student talent and world-class facilities to provide research solutions and help bring ideas to market. This effort is in partnership with the Oregon State University Foundation.

News of the NuScale grant award was welcomed by members of Oregon’s Congressional delegation.

 

“Oregon State University deserves a lot of credit for helping to develop a promising new technology that the Energy Department clearly thinks holds a lot of potential,” said Sen. Ron Wyden, chairman of the U.S. Senate Energy and Natural Resources Committee. “Today’s award shows that investing in strong public universities leads to innovative technologies to address critical issues, like the need for low-carbon sources of energy, while creating private sector jobs.”

U.S. Rep. Peter De Fazio added, “Congratulations to NuScale and Oregon State University. This is a big win for the local economy.” 

“This is an exciting time for us, as our students and faculty get incredibly valuable real-world experience in taking an idea through the startup and commercialization process,” said Kathryn Higley, professor and head of the Department of Nuclear Engineering & Radiation Health Physics. “We continue to work with NuScale as it goes through its design certification process, and we are particularly proud of Jose Reyes for his vision, enthusiasm and unwavering commitment to this concept.”

OSU officials say the development of new technologies such as those launched from NuScale could have significant implications for future energy supplies.

“The nation’s investment in the research of small-scale nuclear devices is a significant step toward a diverse and secure energy portfolio,” said Sandra Woods, dean of the College of Engineering at OSU. “Collaborative research is actively continuing between engineers and scientists at Oregon State and NuScale, and we’re proud and grateful for the role Oregon State plays in assisting them in developing cleaner and safer ways to produce energy.

OSU College of Science to host “The Colorful World of Pigments” on May 5

CORVALLIS, Ore. – Oregon State University will celebrate the blue pigment discovered at the university and its impact on art, culture and industry at an event called “The Colorful World of Pigments” scheduled for May 5 on OSU’s Corvallis campus.

Hosted by the College of Science, the event will include a discussion of color by a panel that will feature the pigment’s discoverer, Oregon State chemist Mas Subramanian; Christopher Manning of the Shepherd Color Company, OSU’s licensing partner for the pigment, named YInMn blue; a color theorist from Nike; and the curator of Harvard University’s 2,500-specimen Forbes Pigment Collection, a scientific catalog of color that includes YInMn blue. 

The Colorful World of Pigments is part of a series known as SPARK: The Year of Arts and Science at OSU. The series explores the intersections of art and science.

Running from 8 a.m. to noon at LaSells Stewart Center, 875 S.W. 26th St., the pigments event also includes an exhibit featuring artworks using YInMn blue, and a wall on which children can color and paint from 10:30 a.m. to noon.

The panel discussion will go from 9 to 10:30 a.m.

At 8 a.m. and 11 a.m., Subramanian will lead tours of the lab where YInMn blue was discovered, and demonstrate how it was discovered. Space on the tours is limited.

YInMn blue was discovered by accident in 2009 when Subramanian and his team were experimenting with new materials that could be used in electronics applications. The researchers mixed manganese oxide – which is black in color – with other chemicals and heated them in a furnace to nearly 2,000 degrees Fahrenheit. One of their samples turned out to be a vivid blue. Oregon State graduate student Andrew Smith initially made these samples to study their electrical properties.

The pigment features a unique crystal structure that allows the manganese ions to absorb red and green wavelengths of light while only reflecting blue. The vibrant blue is so durable, and its compounds are so stable – even in oil and water – that the color does not fade.

These characteristics make the new pigment versatile for a variety of commercial products. Used in paints, for example, they can help keep buildings cool by reflecting infrared light. Better yet, Subramanian said, the pigment’s ingredients are non-toxic.

OSU recognized for sustainability efforts

CORVALLIS, Ore. – Oregon State University has been recognized as a top performer in the 2016 Sustainable Campus Index.

The university ranked seventh overall among universities identified as doctoral/ research institutions, and fifth among all participating universities in the grounds category.

The 2016 Sustainable Campus Index, a publication of the Association for the Advancement of Sustainability in Higher Education (AASHE), highlights top-performing colleges and universities in 17 areas and overall by institution type, as measured by the Sustainability Tracking, Assessment & Rating System, or STARS.

Oregon State was the first Oregon university to be rated by STARS, and received gold designations in 2011, and 2013- 2016.

“Being included in AASHE’s 2016 Sustainable Campus Index is always great, and it’s nice to see a summary of the best sustainability-related work of our fellow higher education institutions,” said Brandon Trelstad, OSU’s sustainability coordinator.

“However, one of the nicest surprises was we were featured in the very short list of colleges and universities with zero or near-zero data errors in their STARS submission. STARS requires input of thousands of data points and I’m glad that the culture of high-quality control and attention to detail in the Sustainability Office, and our partner departments, is recognized.” 

The index also featured a short story on OSU’s humanitarian engineering program, which is one of the few of its kind co-located with a Peace Corps Masters International program. Faculty from engineering, the humanities, public health and forestry all participate in the program. Recent projects by students in the program include creating modeling tools for micro-hydro development in Pakistan and ground-sensing stations for an international trans-African hydro-meteorological observatory.
