Lignin-derived jet fuel displays a superior heat of combustion, higher seal swell properties and a much lower aromatic content compared to Jet-A.
Bin Yang, professor in the Biological Systems Engineering Department at Washington State University (WSU) in Richland, WA, says, “Besides using jet fuel, other propulsion options such as batteries and fuel cells are not suitable for use in long-distance airplance travel in the near future (less than 30 years). This places the aviation industry in the position of needing to find a sustainable alternative to Jet-A. One big concern with using the incumbent jet fuel is its aromatic content, which varies from approximately 8% to 25% by volume, which is key to the density and seal swell characteristics of jet fuel but increases engine soot production. Some approved alternative jet fuels, such as synthetic paraffinic kerosene (SPKs), need the addition of aromatics and others contain aromatics. Ultimately, the aviation industry is seeking a 100% sustainable aviation fuel that produces no emissions.”
An associate professor in the Department of Biological Systems Engineering, Sankaran studies sensor technologies for crop phenotyping and supports plant breeding, crop plant research, and precision agriculture applications. Her research and teaching program supports researchers from other CAHNRS departments and USDA-ARS labs.
Sankaran was honored for her leadership, service, and outreach, for a robust and productive research program, and as a terrific teacher who receives high marks on student evaluations. Highly engaged with her students and post-docs, she is an outstanding mentor for the next generation of scientists. Sankaran strives to impress upon them the importance of following rigorous scientific methods and of communication via prompt publication and involvement in scientific societies.
Automated drones could scare birds off agricultural fields
A Washington State University research team has developed a system for scaring birds, which they detail in a study published in the journal Computer and Electronics in Agriculture. The system is designed to have automated drones available 24 hours a day to scare pest birds, like European starlings or crows, that cost growers millions of dollars a year in lost fruit.
“Growers don’t really have a good tool they can rely on for deterring pest birds at an affordable price,” said Manoj Karkee, associate professor in WSU’s Department of Biological Systems Engineering and the study’s corresponding author. “With further refinement and industry partnerships, this system could work.”
For now, the birds are scared off just by the motion and whirring noises made by drones. But Karkee said that sounds, like distress calls or predatory bird noises, could be added. Builders could even design special drones for the job.
With the CAHNRS Business Center staff reduction, their purchasing related responsibilities will be delegated to our department soon. The department’s office has conducted a successful search for a BSE Fiscal Specialist 1 position. Our new BSE Fiscal Specialist 1 is Mr. Marcelo Martinez.
Marcelo has been going through the Workday related training for the last several days and we hope he will be ready to gradually take over all purchasing processes from the business center.
Marcelo’s office phone number is 509-335-0194, and his email address is email@example.com. Marcelo, welcome to the Biological Systems Engineering family. We are delighted to have you in our department.
An experimental plant-based jet fuel could increase engine performance and efficiency, while dispensing with aromatics, the pollution-causing compounds found in conventional fuels, according to new research.
“When we tested our lignin jet fuel, we saw some interesting results,” said Bin Yang, professor with WSU’s Department of Biological Systems Engineering and corresponding author on the study. “We found that it not only had increased energy density and content but also could totally replace aromatics, which are a real problem for the aviation industry.”
Yang developed a patented process that turns lignin from agricultural waste into bio-based lignin jet fuel. Such sustainable fuel could help the aviation industry reduce dependance on increasingly expensive fossil fuels while meeting higher environmental standards. “This process creates a cleaner, more energy-dense fuel,” Yang added. “That’s exactly what sustainable aviation fuels need for the future.”
Manoj Karkee reports that WSU’s Agricultural Automation group of the Biological Systems Engineering Department has just begun testing their newest robot. The robot is aimed to produce a more stable and efficient pollination and thinning process. The Robotic Pollinator is built with a camera that can detect flower blossoms and determine which need to be pollinated or thinned. Students are currently trying to find the right stage to pollinate the fruit flowers. This comes from trial and error.
Dr. Karkee is trying to develop a robotic solution that would have a camera that works like human eyes to take pictures and works with a “brain”, a kind of artificial intelligence model running on a computer, that detects flowers, locates them and sends the signal to the controller of the robot. This signals the robot where to start thinning the flowers. Karkee thinks the method could also replace honeybees when the robot learns to pollinate flowers.
With the CAHNRS business center losing the last personnel related staff member, the BSE Office initiated a search for an Administrative Assistant 2 (Payroll) permanent position in early February. After reviewing applications and conducting interviews, the search committee unanimously agreed to offer this position to Miss Nina Willis. Most faculty and staff located in Pullman have known Nina since April 2019 when she joined the BSE office as an hourly Clerical Assistant student employee.
We are confident that all of us will appreciate Nina’s professionalism, work ethics, and kindness. At this point, the other BSE Office Staff have started introducing Nina to very complex payroll/personnel policies, procedures, and Workday/myWSU/MyPassport steps and actions.
