Virginia Tech researcher explores using SERS for detecting environmental pollutants

Rapid pollutant detection can prevent widespread outbreaks. While many techniques exist for detecting such contamination, they generally require highly specific instruments for each contaminant. Peter Vikesland, professor of civil and environmental engineering at Virginia Tech, and Haoran Wei of Zaozhuang in Shandong, China, a doctoral student in environmental engineering, describe challenges related to deploying surface-enhanced Raman spectroscopy (SERS) for detection in their paper published by Scientific Reports, “pH-Triggered Molecular Alignment for Reproducible SERS Detection via an AuNP/Nanocellulose Platform.”

SERS has great potential for ultrasensitive chemical analysis and detection of multiple contaminants in a range of environments. Capable of detecting single molecules without excessively expensive equipment or sample pretreatment, SERS has promised rapid field and point-of-use detection that could prevent pollution or biohazard threats and stop outbreaks before they begin. But that promise has gone largely unfulfilled.

One problem is that many of the substances that SERS could potentially detect are moderately hydrophobic, or water-repellent, thus making it harder to attract them to the hydrophilic, or water-loving, gold or silver nanoparticle surfaces used for SERS. Efforts to use molecular traps to better bind target molecules have been explored, but they have added complexity to the material synthesis and tend to produce background signals that complicate data analysis.

In the paper, Vikesland describes a study he and Wei conducted using bacterial cellulose as a SERS platform created by synthesizing nanocomposites made of bacterial cellulose interlaced with gold nanoparticles. Bacterial cellulose makes an excellent base for a SERS substrate. It is low-cost and easily fabricated, and its fibers are nanoscale in diameter and retain their 3-D structure in water.

The study used this platform to attempt to detect a number of common pollutants — carbamazepine, atrazine, and melamine, among others. By manipulating the suspension pH, the authors were able to consistently and reproducibly increase the SERS signal due to the increased affinity for the pollutant to the substrate at low pH.

A SERS platform based on bacterial cellulose could finally help fulfill the promise of this exciting technology. The platform can be synthesized in a one-step process and it can be reused many times. The protocol could simplify and reduce the cost of detecting many compounds. The platform is easy and cheap to synthesize and provides short sampling and detection times.

Vikesland also leads an international team of researchers as the principal investigator for a five-year $3.6 million Partnerships in International Research and Education grant from the National Science Foundation. They seek to halt wastewater-derived antimicrobial resistance dissemination.

ACEC California announces Engineering Excellence Awards that showcase unique projects

The American Council of Engineering Companies, California (ACEC California) recently unveiled the 2016 recipients of its Engineering Excellence Awards, highlighting some uniques projects in the state. In all, 24 California firms representing 27 projects were named, the majority of which were public works projects completed in partnership with local government entities throughout the state. Because of their selection by ACEC California, Honor Award winners are eligible to enter the ACEC national level Engineering Excellence Awards competition. 

"Each year, the recipients of the ACEC California Engineering Excellence Awards represent some of the most innovative solutions to complex public and private sector challenges, including traffic congestion, water resource management, alternative fuel infrastructure, and structural building projects, to name a few," says Brad Diede, executive director for ACEC California. "Engineering continues to help California thrive, and I am deeply proud of our industry accomplishments that directly improve Californians' lives."
ACEC California's annual Engineering Excellence Awards entries are accepted into one of 12 project categories: studies; research and consulting engineering services; building/technology systems; structural systems; surveying and mapping technology; environmental; waste and storm water; water resources; transportation; special projects; small projects; energy; and industrial and manufacturing processes and facilities. An independent panel of judges from the public sector evaluated the projects and made the award selections.
Honor Awards were granted to 14 firms, including Cornerstone Structural Engineering Group of San Francisco for its work on the San Francisco Zoo-South American Rain Forest Exhibit in San Francisco and the R.B. Oliver Bridge Replacement in Tulare County. Cornerstone was contracted by Tulare County in 2010 as the prime consultant to design the state-of-the-art bridge replacement project. Because of the design team's knowledge of the Kings River and partnering between the design team and the County of Tulare, the final design of the project was delivered in less than 2 years, an unprecedented pace for a $20 million bridge replacement project. The project also included development of new bat habitats, which have increased the bat population at the bridge to four times its original number.

Cornerstone provided the structural engineering services required to create the San Francisco Zoo's South American Rain Forest Exhibit, its newest exhibit, as well as seismically retrofit the historic WPA building. The Aviary features a realistic rainforest ecosystem, full of colorful free-flight birds, exotic plants and trees, a two-toed sloth, and the Zoo's first significant herpetological collection, which will include a 15-foot long green anaconda as well as rare tree frogs, turtles, lizards, and snakes.

Mark Thomas and Company of San Jose received an Honor Award for its work on the I-280/ I-880/ Stevens Creek Boulevard Interchange Project in San Jose. The I-280/I-880/Stevens Creek Boulevard Interchange Project, delivered for the Santa Clara Valley Transportation Authority (VTA), improved this highly congested facility. The existing interchange was a full cloverleaf configuration originally constructed in 1959. Since that time, the cities of San Jose and Santa Clara have grown tremendously, and the facility had become outdated. Additionally, the interchange is adjacent to the busiest shopping area in Santa Clara County, including Valley Fair and Santana Row. The reconfiguration allowed for increased traffic capacity, enhanced bicycle and pedestrian facilities, and  accommodated the Stevens Creek Boulevard Bus Rapid Transit (BRT) alignment. Lastly, the project design incorporated aesthetic treatments and sustainable stormwater handling facilities.

McMillen Jacobs Associates of Walnut Creek was honored for its work on the Bay Tunnel in Menlo Park/ Newark, the first tunnel excavated under the San Francisco Bay. The $288 million project is a successful and significant part of San Francisco Public Utilities Commission's (SFPUC) $4.6 billion Water System Improvement Program to upgrade the Hetch Hetchy Water System, which brings water through gravity-fed pipes from Yosemite National Park to the San Francisco Bay Area. The Bay Tunnel extends 5 miles under the Bay, replacing the aging water pipeline infrastructure built in the 1920s and 1930s that presently traverses the Bay on wooden trestles. The tunnel provides up to 224 million gallons per day of high-quality drinking water to about 2.6 million of SFPUC's customers in the Bay Area.

Walter P Moore of San Francisco, received an award for its work on the Air Traffic Control Tower and Intergraded Facilities Building at San Francisco International Airport. The iconic new tower, which replaced SFO's long outdated 1960s-era control tower, is the first air traffic control tower delivered through a partnership between the airport and the FAA. The tower relies on an innovative vertical post-tensioned system to self-right the structure during a major seismic event, ensuring that air traffic controllers remain fully operational after a magnitude 7.5 earthquake. This is crucial since the airport is just four miles from the San Andreas Fault.

Stover Engineering of Crescent City and COWI (formerly Ben C. Gerwick, Inc.) of Oakland were cited for their work on the Crescent City Harbor Inner Boat Basin Reconstruction Project  in Crescent City. This $32.7 million tsunami-damage repair project is the first known marina in North America designed to withstand a significant tsunami event. Marinas currently have no established design criteria for tsunamis, so the project required engineering judgment to justify the repairs to both funding and permitting agencies. Modeling performed to establish the tsunami loads was validated by a subsequent tsunami that occurred prior to final design of the project.

Duke engineers help Siri hear through a cocktail party

People trying to talk to Siri, the operating system used on various Apple devices, may soon no longer have to look like they’re about to eat their iPhones, thanks to a new technology demonstration that solves the problem of crowd noise. In a crowded room with voices coming from every direction, the human auditory system is incredibly good at homing in on a single voice while filtering out the background jabber, but computers are not.

A new approach from engineers at Duke University, however, may soon improve their performance in loud environments. They have developed a sensor that uses metamaterials -- the combination of natural materials in repeating patterns to achieve unnatural properties -- and compressive sensing to determine the direction of a sound and extract it from the surrounding background noise. Once miniaturized, the device could have applications in voice-command electronics, medical sensing devices that use waves, like ultrasound, and hearing aids and cochlear implants. Their study appeared in the Proceedings of the National Academy of Sciences.

“We’ve invented a sensing system that can efficiently, reliably, and inexpensively solve an interesting problem that modern technology has to deal with on a daily basis,” says Abel Xie, a PhD student in electrical and computer engineering at Duke and lead author of the paper. “We think this could improve the performance of voice-activated devices like smart phones and game consoles while also reducing the complexity of the system.”

The proof-of-concept device looks a bit like a thick, plastic, pie-shaped honeycomb split into dozens of slices. While the honeycomb’s openings may all look the same, their depth varies from hole to hole. This gives each slice of the honeycomb pie a unique pattern.

“The cavities behave like soda bottles when you blow across their tops,” says Steve Cummer, professor of electrical and computer engineering at Duke. “The amount of soda left in the bottle, or the depth of the cavities in our case, affects the pitch of the sound they make, and this changes the incoming sound in a subtle but detectable way.”

When a sound wave gets to the device, it becomes slightly distorted by these cavities. And that distortion has a specific signature depending what slice of the pie it passed over. After being picked up by a microphone on the other side, the sound is transmitted to a computer that can separate the jumble of noises based on these unique distortions. The researchers tested their invention in multiple trials by simultaneously sending three identical sounds at the sensor from three different directions. It was able to distinguish between them with a 96.7 percent accuracy rate.

While the prototype is six inches wide, the researchers believe it could be scaled down and incorporated into the devices we use on a regular basis. And because the sensor is made of plastic and does not have any electric or moving parts, it is extremely efficient and reliable.

“This concept may also have applications outside the world of consumer electronics,” Xie reports. “I think it could be combined with any medical imaging device that uses waves, such as ultrasound, to not only improve current sensing methods but to create entirely new ones.
With the extra information, it should also be possible to improve the sound fidelity and increase functionalities for applications like hearing aids and cochlear implants. One obvious challenge is to make the system physically small. It is challenging, but not impossible, and we are working toward that goal.”

This work was supported by a Multidisciplinary University Research Initiative under a grant from the Office of Naval Research.

White House honors FIU bridge expert Atorod Azizinamini

The White House and the U.S. Department of Transportation have honored Atorod Azizinamini, chair of the Department of Civil and Environmental Engineering at Florida International University’s College of Engineering and Computing, for his innovations in making the nation’s aging bridges safer. Azizinamini has been named a 2015 White House Transportation Champion of Change. The White House Champions of Change Program highlights the stories and examples of citizens across the nation who are leading projects and initiatives that move their communities forward.

The U.S. Department of Transportation and the White House Office of Public Engagement hosted White House Champions of Change, focused on Beyond Traffic: Innovators in Transportation for the Future. Azizinamini and the other honorees were recognized as leaders in advancing transportation and change that benefits the country’s transportation system. They also participated in panel discussions. “At FIU, we are providing efficient and economical solutions for the many challenges we face with our bridges and infrastructure,” Azizinamini says. “Being named a Champion of Change is recognition of the impact we have had.”

Azizinamini has devoted his career to developing solutions for aging bridges. Currently, about 24 percent of more than 610,000 bridges in the United States are deficient, and about 45 percent of all U.S. bridges are shorter than 60 feet. To address this issue, Azizinamini invented the Folded Plate Steel Bridge System, which provides an economical, long-term solution for replacing outdated short-span bridges. It allows on-site construction of a bridge over a few days, using less costly materials and lasting longer, resulting in lower costs and limited impact to traffic. In 2014, with support from the second Strategic Highway Research Program, Azizinamini developed the first comprehensive guide to enhancing the service life of bridges. The first application of the guide was at the Tappan Zee Bridge in New York.

Azizinamini is director of FIU’s Accelerated Bridge Construction University Transportation Center (ABC-UTC), focused on developing technology and methods to improve bridge design and construction. The ABC-UTC was established by the U.S. Department of Transportation in 2013 and works closely with the Federal Highway Administration and the American Association of State Highway and Transportation Officials to advance accelerated bridge design and construction through research, workforce development, and technology transfer.

“Dr. Azizinamini’s visionary bridge designs are what our country needs for the 21st century – cutting-edge, cost-efficient, and safe,” says Ranu Jung, interim dean for the College of Engineering and Computing. “In addition to his contributions to bridge engineering, he has ensured that our students learn to think in terms of finding solutions and impacting the local, national, and global community.”

EPA awards green infrastructure grant to Kansas State University

The U.S. Environmental Protection Agency has awarded a $20,000 grant to Kansas State University to carry out a green infrastructure demonstration and training project on its campus in Manhattan, Kansas. Faculty and students will create “living laboratories” to conduct green infrastructure monitoring at two on-campus sites, the rain garden at the International Student Center and the meadow at the Marianna Kistler Beach Museum of Art.

According to the project narrative, faculty will devise a “green infrastructure monitoring curriculum” that will offer “technical training on water quality analysis, runoff modeling, and overall ecological health assessments.” Students from different disciplines will collaborate on the monitoring program. They will record and analyze data to gauge performance, then develop communication materials, including brochures and a touch screen at the museum. “Measuring green infrastructure’s impact is important and so is training individuals who can make contributions to the field,” says Ken Kopocis, EPA’s deputy assistant administrator for water. “By giving students hands-on experience with green infrastructure monitoring, this project achieves both objectives.”

Green infrastructure uses vegetation, soils, and natural processes to manage wet weather runoff, treating stormwater as a resource rather than a waste. It can enhance resiliency for communities and landscapes faced with water pollution and climate change impacts by increasing water supplies, reducing flooding, combatting urban heat island effect, and improving water quality.

The award encourages sustainable stormwater management by educating the next generation of scientists, designers, and engineers about green infrastructure. By supporting demonstrations and training, colleges and universities can advance the implementation of green infrastructure to protect water quality. This award builds on the success of EPA’s Campus RainWorks Challenge, in which faculty and student teams design green infrastructure projects for their campuses. Kansas State won a $2,000 first-place prize in 2013. EPA also awarded a $20,000 grant to Mississippi State University to design and construct a 1,500-square-foot rain garden to manage runoff from a nearby building.
