Prof. Bo Sun has received an NSF CAREER award for his biophysics research. Please look at the longer IMPACT article for details. (And he’s also the 2019 Richard T. Jones New Investigator Award for the Medical Research Foundation of Oregon, more details on that after the ceremony in Portland later this term.)
A belated post from last Fall:
Ethan Minot, associate professor of physics, received the Milton Harris Award in Basic Research for his impressive accomplishments as a scientist. At Oregon State, Minot has built a world-class materials physics laboratory for the study of the structure and properties of carbon nanomaterials and devices for nanoelectronics.
His research at Oregon State has pushed the limit of fundamental properties of nanoelectronic devices, which have a broad range of applications to biosensing and solar energy harvesting. Some of his achievements are: identifying the fundamental noise mechanism that limits the performance of graphene biosensors in liquid environments; becoming the first to electrically generate and detect single point defects; reaching a new level of control over point defect chemistry; and other pioneering advances in the development of high-quality nanodevices and biosensors.

Oksana Ostroverkhova, Professor of Physics at Oregon State University, and a leading expert on organic electronics, is the editor of the second edition of Elsevier Publishing Company’s “Handbook of Organic Materials for Electronic and 
Photonic Devices”. This 911-page handbook provides an overview of the materials, mechanisms, characterization techniques, and structure property relationships of organic electronic and photonic materials and describes the latest advances in the field. Oksana selected the topics, solicited contributions from the authors, and edited the entire book. and the result, at least a year in the making, is a comprehensive overview of a quickly-developing field.
This is the second handbook that Oksana has edited. The first, “Handbook of Organic Materials for Optical and (Opto)Electronic Devices“, appeared in 2013 and was published by Woodhead Publishing. Oksana also wrote an extensive review of her own on a related topic that was published in Chemical Reviews in 2016: “Organic Optoelectronic Materials: Mechanisms and Applications”
Chemical Reviews 116, 13279 – 13412 (2016). This review is already her most highly cited publication from her time at Oregon State University.
The Ostroverkhova group’s work on bee vision had attracted a lot of attention!
KATU has an interview with Oksana Ostroverkhova at: https://katu.com/news/local/wild-bees-are-attracted-to-blue-fluorescent-light-oregon-state-university-research-finds
Sci-news has an article http://www.sci-news.com/biology/bees-blue-fluorescent-light-06121.html
and there is a press release to go with their recent paper in Journal of Comparative Physiology A. https://link.springer.com/article/10.1007/s00359-018-1269-x
CORVALLIS, Ore. – Researchers at Oregon State University have learned that a specific wavelength range of blue fluorescent light set bees abuzz.
The research is important because bees have a nearly $15 billion dollar impact on the U.S. economy – almost 100 commercial crops would vanish without bees to transfer the pollen grains needed for reproduction.
“The blue fluorescence just triggered a crazy response in the bees, told them they must go to it,” said the study’s corresponding author, Oksana Ostroverkhova. “It’s not just their vision, it’s something behavioral that drives them.”
The findings are a powerful tool for assessing and manipulating bee populations – such as, for example, if a farmer needed to attract large numbers of bees for a couple of weeks to get his or her crop pollinated.
“Blue is broad enough wavelength-wise that we needed to figure out if it mattered to the bees if the light emitted by the sunlight-illuminated trap was more toward the purple end or the green end, and yes, it mattered,” Ostroverkhova said. “What’s also important is now we’ve created traps ourselves using stage lighting filters and fluorescent paint – we’re not just reliant on whatever traps come in a box. We’ve learned how to use commercially available materials to create something that’s very deployable.”
Fluorescent light is what’s seen when a fluorescent substance absorbs ultraviolet rays or some other type of lower-wavelength radiation and then immediately emits it as higher-wavelength visible light – think about a poster whose ink glows when hit by the UV rays of a blacklight.
Like humans, bees have “trichromatic” vision: They have three types of photoreceptors in their eyes.
Both people and bees have blue and green receptors, but the third type for people is red while the third kind for bees is ultraviolet – electromagnetic energy of a lower wavelength that’s just outside the range of human vision.
Flowers’ vibrant colors and patterns – some of them detectable only with UV sight – are a way of helping pollinators like bees find nectar, a sugar-rich fluid produced by plants. Bees get energy from nectar and protein from pollen, and in the process of seeking food they transfer pollen from a flower’s male anther to its female stigma.
Building on her earlier research, Ostroverkhova, a physicist in OSU’s College of Science, set out to determine if green fluorescence, like blue, was attractive to bees. She also wanted to learn whether all wavelengths of blue fluorescence were equally attractive, or if the drawing power tended toward the green or violet edge of the blue range.
In field conditions that provided the opportunity to use wild bees of a variety of species – most bee-vision studies have been done in labs and used captive-reared honeybees – Ostroverkhova designed a collection of bee traps – some non-fluorescent, others fluorescent via sunlight – that her entomology collaborators set up in the field.
Under varying conditions with a diverse set of landscape background colors, blue fluorescent traps proved the most popular by a landslide.
Researchers examined responses to traps designed to selectively stimulate either the blue or the green photoreceptor using sunlight-induced fluorescence with wavelengths of 420 to 480 nanometers and 510 to 540 nanometers, respectively.
They found out that selective excitation of the green photoreceptor type was not attractive, in contrast to that of the blue.
“And when we selectively highlighted the blue photoreceptor type, we learned the bees preferred blue fluorescence in the 430- to 480-nanometer range over that in the 400-420 region,” Ostroverkhova said.
Findings were recently published in the Journal of Comparative Physiology A. The Agricultural Research Foundation and OSU supported this research.

Jim Ketter, who served as lab guru and instructor for many years, passed away on June 6th 2018. Jim joined our department in 2005 after a varied career as a geophysicist, high school teacher, graduate student and physics instructor at LBCC and Oregon State. He was a warm and sensitive instructor and the go-to gadget guy who kept our labs running and our department presentable. In addition to the considerable load of teaching and keeping our labs humming, he loved doing outreach – Discovery days, supervising the SPS and generally bringing his enthusiasm for physics to everyone he met.
