VCU Engineering researchers are working to make clean energy easier and cheaper

Lane Carasik, Ph.D., assistant professor in VCU’s Department of Mechanical and Nuclear Engineering, is developing methods to make clean energy more cost-effective. He’s motivated by a simple principle. “The cheaper we make renewable and clean energy, the easier it is to implement it,” he said. With $100,000 in seed funding from the Jeffress Trust Awards Program, Carasik and his Fluids in Advanced Systems and Technology (FAST) research group are designing efficient, low-cost enhancements to equipment used in solar, nuclear and geothermal energy systems. Jeffress Trust awards support high-impact, one-year projects that integrate computational and quantitative scientific methodologies across a broad range of scientific disciplines. These energy systems use heat exchangers, which take energy from heat generation components and convert it to electricity. Heat exchangers usually comprise two working substances such as water, steam or air separated by tubes or plates. The FAST research group is optimizing a specialty insert that can be placed inside a heat exchanger’s tubes to improve performance. To visualize the insert’s form, imagine holding a piece of metal tape in both hands and gently twisting it. See the FAST Lab and examples of the heat transfer enhancements being designed there. “A liquid running through a tube is relatively undisrupted by the geometry of the tube or the shape of the fluid,” Carasik said. “But this twisted tape component spins the fluid. This increases turbulence, which increases heat transfer.” While “twisted tape” inserts are already in use in some advanced energy systems, the process of fabricating them has been limited by mechanical constraints. Typically, the inserts are placed inside a tube and tack welded at either end. But because of the metal’s limited tensile strength, these inserts can only be twisted a little before they break down and cause manufacturing defects. 3D printing, on the other hand, allows for a more complex — and effective — insert that can be used to characterize heat transfer performance. “With additive manufacturing, you can actually print tighter, ‘twistier’ versions of them,” Carasik said. “You can also add your own intentional defects to find out how to make the heat transfer better and improve the performance of the whole system.” Each geometric form the research group prints and tests starts with a world of calculations: thermal-hydraulics design calculations, solid geometry, material properties and more. From there, components are computer-designed, then printed in the Mechanical and Nuclear Engineering Innovation Lab. Finally, they are tested in the FAST research group’s Modular Separation Effects Testing Facility (MSEFT), a scaled testing loop that emulates the operating conditions experienced by these components. Undergraduates — even first-year students — participate in each step of the process, alongside Carasik, postdoctoral research associate Cody Wiggins, Ph.D., and doctoral student Arturo Cabral. “I really like getting students into research early on, Carasik said. “By the time they’re three years in, they’re working at a level I would expect from bachelor’s level engineers in industry.” Senior Meryem Murphy was curious about undergraduate research but had never really participated. “One day, I was arguing with Arturo about something and Dr. Carasik said, ‘If you’re like this all the time, you should work for the lab.’” She took him up on it and spent her junior year working on an MSEFT redesign and running an experiment to see if 3D-prototyped concepts can be replicated with test metals. Over the summer, Murphy interned with Atomic Alchemy, a medical radioisotope startup in Boise, Idaho. She said the position built on the hard, and soft, skills she gained in the lab. “Sometimes in class, you’re required to collaborate,” she said. “But in research, it’s just ‘what you do’ to get it done.” Rising sophomore Ryan McGuire is also looking forward to starting his second year in the lab. During his freshman year, McGuire helped develop a 3D printing technology to duplicate sequences of 3D-printed parts for the FAST research group. It’s called Retrospective Additive Manufacturing Sequencing — RAMS for short. McGuire said the thrill of solving problems in the lab has made him reassess his own goals. “When I was younger, I wanted to be [famous],” he said. “But now I no longer want to be famous. Research seems like more fun.” Upon hearing about McGuire’s change in priorities, Carasik said, “Researchers can be famous too, and for good reason.”

MEDIA RELEASE: Drivers asked to stay alert and slow down as students prepare to return to school

COVID-19 has changed the way we do many things and, the return to school is no different. This year, children are being encouraged to walk and bike to school to support social distancing. In some parts of Ontario, the start of school is even being staggered, and some children may be doing a combination of in-person and distance learning. In addition, many children will be using masks that may obstruct their line of sight. For these reasons, CAA South Central Ontario (CAA SCO) is reminding everyone to take extra caution this year while travelling through school zones. “As students prepare to reunite with friends and classmates after a six-month hiatus, many might forget to take the extra precautions needed to stay safe. This means there is an even bigger responsibility to watch for children travelling to and from school,” says Raymond Chan, manager of government relations for CAA SCO. Keeping our kids and neighbourhoods safe is a shared responsibility. That’s why this year, we are providing FREE “Slow Down Please” lawn signs to anyone living in South Central Ontario. When well-placed, these signs aim to make roads safer for children and those living in the community. Remember to check local bylaws before installing signs on private property. Anyone can pick up a maximum of two signs at any CAA Store, while quantities last. Drivers can also use the following CAA tips to ensure they are staying safe in school zones. Make eye contact with children: With the excitement of back to school, anticipate that children may not easily see or hear your moving vehicle. Make eye contact with passing pedestrians and cyclists. Reduce traffic by walking: Incorporate a short walk into your commute to school. CAA encourages parents to park a block away and walk to school, if possible, to reduce congestion and make school zones safer. Slow down: Know the speed limit in your neighbourhood’s school zones and respect them. Watch for more school buses: Always stop for the buses’ flashing lights and wait for children to get safely on or off. Stay alert and watch for children or parents crossing the road when the bus moves on. Choose a safe spot to drop off and pick up your children from school: Follow your school’s rules and don’t park illegally, it can put your child’s safety at risk. Instead, use the designated drop off areas or consider a spot a bit farther away from school that is easily accessible and safe. The above tips are crucial in maintaining a safe school zone. According to a CAA poll, nearly 25 per cent of drivers reported witnessing a near miss or collision in a school zone, more than half of which involved a child. The poll also revealed 70 per cent of Canadians said they have witnessed someone speeding in a school zone. CAA also supports safety in school zones through the CAA School Safety Patrol program. CAA designed this program to protect, educate, and empower elementary school children on safe road-crossing practices. Our Ontario Road Safety Resource is a toolkit for teachers to educate Ontario youth about road safety.

Being all that you can be and more – Find out how Georgia Southern University is helping soldiers boost their performance

A new program being offered by the Waters College of Health Professions at Georgia Southern University is helping soldiers with the 3rd Infantry Division (ID) rank up their readiness by offering a new Tactical Athlete Certificate (TAC) program. This program is designed to help soldiers improve their performance, avoid musculoskeletal injuries in physical training, receive college credits and points toward promotions. The program comprises three courses including a basic course, trainer course and programming course. “The Tactical Athlete Certificate is a beneficial program for both the military as a whole and the individual soldier,” said Nancy Henderson, Ph.D., assistant professor in the Department of Rehabilitation Sciences. “The military gains more knowledgeable soldiers who can develop science-based and comprehensive physical training plans, and the individual soldier benefits by receiving college credits, which can help them as they advance in their military careers.” Each course is a three-week hybrid course with two weeks online and one week of face-to-face instruction and could be completed in one semester. Institutional fees are waived for active-duty military, and the admissions process does not require a minimum GPA or SAT/ACT score.

High tech and contact free. Check out how Georgia Southern became the first university in Georgia to enlisted robots to enhance campus health and safety.

Six-wheeled robots independently navigating the streets and sidewalks on Georgia Southern’s Statesboro Campus may look a little strange. But it will soon be commonplace as these ground robots, which look like a cooler on wheels, have been mapping routes to campus locations in preparation for contactless food delivery this fall. Thanks to a partnership with Starship Technologies, Georgia Southern is the first university in the state to provide faculty, staff, and students with 20 autonomous delivery robots to deliver food from on-campus dining locations to designated pickup locations. Since August, Starship’s robots have been delivering food ordered on the Starship app from University dining facilities and places such as Starbucks, Market Street Deli and Sushi with Gusto to patrons around campus. The robots, which are energy efficient, can have their location and delivery time tracked by recipients through the app. They can also maneuver around obstacles such as pedestrians. “My hope is that it brings a sense of enhanced safety and convenience to our students,” said Clint Bridges, IT Business Owner at Georgia Southern University. “While we are all living through the COVID-19 pandemic, we are hoping that the robots will allow for easier social distancing. The fact that students can order a meal from their residence hall room and have it delivered by an automated delivery vehicle keeps them close to home where they can feel the most at ease and still enjoy a meal from one of our dining locations on campus.” Starship Technologies officials say the robots have been proven to be popular. “Students are looking for ways to get food delivered in the safest and most convenient way possible at the moment,” said Ryan Tuohy, senior vice president of Business Development at Starship Technologies. “Our robots are fast, friendly and help make life a little bit easier, especially in these challenging times.”   If you are journalist and would like to know more about how Georgia Southern is constantly innovating and discovering new ways to safely enhance the on-campus experience for students - simply reach out to Georgia Southern Director of Communications Jennifer Wise at jwise@georgiasouthern.edu to learn more and arrange an interview today.

Georgia Southern University – is thinking BIG when it comes to entrepreneurs and small business

Through the CARES Act and the U.S. Department of Commerce, Georgia Southern University’s Business Innovation Group (BIG) has received $300,000 in grant funding to expand its services to the region in an effort to help communities and businesses respond to and recover from the economic impact of the coronavirus pandemic. “This will really allow us to help businesses and entrepreneurs throughout the entire state ideally get access to the skills, knowledge and services that Georgia Southern has to offer,” said Dominique Halaby, DPA, director of BIG. Over the next two years, BIG will use these funds to expand their services through the Georgia Enterprise Network for Innovation and Entrepreneurship (GENIE). “We’re hoping that we can demonstrate to budding entrepreneurs and small business owners that Georgia Southern can help them develop and grow,” Halaby said. “We are hopeful that in two years’ time people are going to have a heightened aerial view of awareness for Georgia Southern and our Business Innovation Group services, but more importantly, that they are going to get the type of resources to be able to launch the business that they’ve always wanted to launch.” Halaby said offering these resources to the region is important for economic growth. “Any time that we have an ability to do something, we have a responsibility to do it,” Halaby said. “The needs of our community are great. Our ability to service those needs by connecting those with the resources on our campus and with the skills that we have fostered within BIG puts us in a very unique position. This way, we are able to provide services to help as many entrepreneurs and to help as many people looking for jobs as we possibly can.” BIG will also use part of the grant funding to work with Georgia Southern faculty to strengthen patent and licensing activity. “We’re working with our intellectual property committee and through the University to let faculty know that if they’ve got a concept, that BIG can help them flesh that out. We can work with them to do an analysis to see the marketability for their concept and determine if it’s patentable or licensable,” Halaby said.

“Be innovative, flexible, nimble and willing to adapt and change.” Georgia Southern University’s president delivers the Fall 2020 State of the University

Georgia Southern University President Kyle Marrero delivered a virtual State of the University fall 2020 address to faculty and staff, broadcast live from the Performing Arts Center on the Statesboro Campus on Aug. 12. Maxing out with 1,507 viewers at one point, University members tuned in from remote locations to hear the president discuss how Georgia Southern is successfully adapting during extraordinarily difficult times and will continue to be nimble during the fall semester. “We are being asked to be innovative, flexible, nimble and willing to adapt and change,” Marrero said after welcoming all back to the three campuses. “And I want to thank you. You all have been tremendous, remarkable, heroic even, as we made it through these times and as we navigate through these uncertain times.” Marrero touted the herculean efforts of faculty and staff, who maintained the integrity of the University’s five pillars — student success, teaching and research, inclusive excellence, operational efficiency, effectiveness and sustainability, and community engagement, in the midst of a pandemic that caused the University to move fully online in March. He cited specific examples of performance excellence since March with the following collective efforts: Moved more than 5,000 classes to fully online to complete the Spring 2020 Semester; Delivered summer term fully online while seeing credit-hour generation move up by more than 4%, compared to the Summer 2019 Semester; Moved 4,600 students out of housing and provided support for more than 100 students who remained on campus; Refunded almost $11 million in housing, dining and fees to students; Held virtual Spring 2020 Commencement, viewed by more than 100,000 worldwide; Provided more than $11 million in CARES Act grant funding directly to students; Developed and began implementation of Initial Return to Campus and Return to Campus Plans, based on input from more than 130 faculty staff across campus and public health guidance from the Centers for Disease Control and Prevention and the Georgia Department of Public Health; Modeled a 14% state budget reduction for FY21, then completed a 10% realized reduction, totaling $14.2 million; Developed and implemented flexible and remote work processes; Assessed and modified almost 5,000 courses for fall 2020; Prepared campus with signage, cloth face coverings, face shields, PPE, hand sanitizer stations; Formed and implemented the CARES Service Center; Continued communication, coordination and monitoring of community health care providers, public/private schools, municipalities and agencies. Marrero also presented August figures showing that fall 2020 enrollment looks strong compared to this same time last year, however, he was quick to note that the figures may fluctuate based on various factors throughout the semester. Final fall enrollment figures will be released in October. “We can continue to move forward,” he said. “We can continue to elevate and live our mission and our vision and our values even in these times. We will adapt, we’ll be nimble and we’ll ensure that every day that the public health and safety of our faculty, staff, students and our community is of paramount importance. “I am confident that we are ready as we can be and together we’ll assess and navigate the entirety of the fall semester with the goal and outcome of our students being successful. As a whole Georgia Southern University can make it through this together.” If you are journalist and would like to know more about Georgia Southern university and how it is succeeding during COVID-19, simply reach out to Georgia Southern Director of Communications Jennifer Wise at jwise@georgiasouthern.edu to arrange an interview today.

Environment-Friendly Compound Shows Promise for Solar Cell Use

A widespread transition to solar energy will depend heavily on reliable, safe, and affordable technology like batteries for energy storage and solar cells for energy conversion. Nikhil Koratkar, an endowed professor of mechanical, aerospace, and nuclear engineering at Rensselaer, has dedicated much of his research to exploring ways to make a wide-range of batteries more efficient, affordable, and safe. In research published in Advanced Functional Materials, Koratkar and a team of engineers, material scientists, and physicists demonstrated how a new material — a lead-free chalcogenide perovskite — that hadn’t previously been considered for use in solar cells could provide a safer and more effective option than others that are commonly considered. “The National Academy of Engineering has defined 14 grand challenges; one of those is to make harvesting energy from the sun cheaper and more widespread,” Koratkar said. "That’s the motivation of this work, to come up with new materials that could rival the efficiency of silicon, but bring down the cost of manufacturing solar cells, and that is the key to achieving this goal.” Koratkar is available to talk about this recent discovery, and his broader expertise and research in energy storage.

Check out how one Georgia Southern student is changing the national narrative on inclusion in the sciences

As a Black wildlife conservationist and field biologist devoted to the study of birds, Corina Newsome, a graduate student at Georgia Southern University, has long been confronted with the lack of diversity in the natural sciences. However, earlier this year, social media became a powerful interface for Newsome and a group of fellow Black scientists around the country, who discovered one another online and quickly formed a camaraderie. “We all met on Twitter,” Newsome explained. “I happened upon a tweet or post and I’m like, ‘Is that a Black person?’ Turns out they’re a Black scientist in herpetology or ornithology or whatever, so I immediately connected with them and said, ‘Hey, can we just know each other?’” Soon after, a video of a racially motivated confrontation in Central Park recorded by science editor and avid birder Christian Cooper went viral, and the network of 30 scientists banded to launch Black Birders Week on May 31. The group of virtual events, coordinated with hashtags like #BlackInNature, #AskABlackBirder and #BirdingWhileBlack, celebrated Black birders and naturalists from around the globe while pushing for inclusion and safe spaces in the outdoors. “For far too long, Black people in the United States have been shown that outdoor exploration activities, such as birding, are not for us,” Newsome stated in a video posted on social media to announce the weeklong initiative’s kickoff. “Well, we’ve decided to change that narrative. A group of Black birders, explorers and scientists got together to start the first-ever Black Birders Week. Help us to show the world, especially the next generation of young, Black birders and nature enthusiasts, that we exist, that they are welcome and that this space belongs to them, too.” The response was monumental as a multitude of Black scientists and naturalists shared their favorite birds, nature shots and professional settings online. “Black Birders Week showed us we are not actually alone,” said Newsome. “It created a community of Black people around the world. Just being on my phone and seeing a Black family outside or a Black professor somewhere teaching ornithology, people doing the thing that I do, encourages me. That makes me feel like it is possible to do well.” Newsome quickly became one of the recognizable faces of Black Birders Week and was featured in The New Yorker, Washington Post, National Geographic and NPR, among other media outlets. She also participated in a virtual roundtable discussion hosted by the National Audubon Society and included Cooper and fellow Georgia Southern student Alex Troutman. Online responses from the organization’s 1.4 million Facebook followers were largely optimistic, however there was some backlash. “We got comments from people saying we are creating division by talking about this,” Newsome said. “The division was already there. Now you know about it, and you’re uncomfortable. But we’ve been uncomfortable.” Such candor has especially captured the attention of students. “The most overwhelming, positive responses have been from young, Black people in college or pre-college who are interested in the sciences, messaging me or emailing me and saying, ‘It’s meant so much to see you doing your work,’” she said. Newsome noted that multiple wildlife and government agencies have also reached out, demonstrating that they are in the process of making structural changes within their organizations to expand diversity efforts. “Seeing these things actually materialize has been mind-blowing, and again, that’s because of the work of the group, the collective work of this movement,” she said. “I think that the one really encouraging element of that has been them choosing to use their platform to amplify our voices at the expense of losing some of their constituents.” While Newsome’s passion, “the thing that lights a fire under me constantly,” can be found at the intersection of wildlife conservation and human rights, birds continue to be her feathered muses. “They weigh sometimes a fraction of an ounce,” she said. “They are so physically fragile, yet they make some of the most physically intense migrations on the globe, from the tip of North America to the tip of South America. Birds as tiny as a hummingbird that weigh a tenth of an ounce fly over the Gulf of Mexico nonstop for over 18 hours. Just think of how much they’re accomplishing, even though they are easily one of the most fragile creatures on the planet. It feels oxymoronic, but it’s real. “Birds remind me that things that seem impossible happen.” If you are journalist and would like to know more about this particular story simply reach out to Georgia Southern Director of Communications Jennifer Wise at jwise@georgiasouthern.edu to arrange an interview today.

Airing commercials after political ads actually helps sell nonpolitical products

About $7 billion reportedly will be spent this fall on television and digital commercials from political campaigns and political action committees, filling the airwaves with political ads many viewers dislike. Companies running ads immediately afterward have been concerned about the potential of a negative spillover effect on how they and their products and services are perceived. But new research from the Indiana University Kelley School of Business finds that the opposite is true. Contrary to mainstream thought, political ads instead yield positive spillover effects for nonpolitical advertisers. And this happens regardless of whether the political ad is an attack ad or not, who the ad supports, and whether it's sponsored by a candidate, political party or PAC. Political advertising accounts for nearly 10 percent of all U.S. television ad revenue. The findings are in the article "Impact of Political Television Advertisements on Viewers' Response to Subsequent Advertisements" -- accepted for publication in Marketing Science -- by Beth Fossen, assistant professor of marketing; Girish Mallapragada, associate professor of marketing and Weimer Faculty Fellow; and doctoral candidate Anwesha De, all from the Kelley School of Business. "Our investigations provide insights into the previously unexplored ad-to-ad spillover effects and, more broadly, provides insights into how political messages influence consumers," Fossen said. "Nonpolitical ads that follow political ads benefit through a reduction in audience decline and an increase in positive post-ad chatter." Using data for 849 national prime-time ads during the 2016 U.S. general election, the researchers found that ads airing after a political commercial saw an 89 percent reduction in audience decline and a 3 percent increase in post-ad chatter online. Their findings remained consistent when examining the effect by TV network and political party affiliation. "It seems reasonable to assume that Fox News viewers are more likely to be positively stimulated by pro-Republican ads than viewers of other channels," researchers wrote. "However, evidence from our data suggests that the positive spillover from pro-Republican ads is not higher and is nearly lower on Fox News viewership decline than when pro-Republican ads air on other channels." They found a similar trend when it came to advertising on MSNBC, whose viewers frequently identify with the Democratic Party and progressive causes. Mallapragada said the findings show that television networks and stations can leverage the positive spillover effects on subsequent ads by implementing differential pricing and systematic ad sequencing. Prevailing belief in the business industry has suggested that political ads on television hurt the effectiveness of subsequent ads. To illustrate this concern, during the 2020 Super Bowl, game broadcaster Fox isolated political ads from other paying advertisers in their own ad breaks, a decision that cost the network millions in ad revenue, because it ran nonpaid show promos alongside the political ads instead of commercials from paying advertisers. "The insights from this research enable advertisers to advocate for the inclusion of ad positioning in ad buys and, specifically, negotiate that their ads follow political ads," he said. "Our results may also encourage advertisers outside of the television context to experiment with advertising next to political content, an experimentation that may be especially beneficial for online advertisers given that they commonly blacklist political topics to avoid having their ads appear near political content."

Expert comment: Joe Biden formally nominated at US Democratic Convention

Dr Trevor McCrisken, expert in US politics at the University of Warwick (UK), comments: The Democratic Party brought out its heavy hitters to formally nominate its presidential candidate Joe Biden last night, with two former US Presidents, Jimmy Carter and Bill Clinton. The Virtual Convention may not have all the excitement and hoopla of the usual pre-election showcase, but the Party is doing its best to unite progressives and moderates in the party behind the Biden-Harris ticket. What's more they're reaching out to disgruntled Republicans with endorsements for Biden from key figures including none other than former Secretary of State Colin Powell, who has served in three Republican presidencies.
