Keuka College Associate Professor of Chemistry Andrew Robak has used fine art and photography to educate others about the intricacies of science, and his latest student collaboration showcases another new perspective.
In 2012, Robak collaborated with Kat Andonucci ’13 to produce “The Art of Chemistry,” a unique exhibit featuring chemical experiments often photographed by Andonucci at slow speeds or in low light to highlight the array of colors, shapes and textures within a variety of chemical solutions, reactions and even optical illusions. This time, Robak’s collaboration with biology major Phil Longyear ’14, a Rushville resident, explores the variety of natural elements from the Periodic Table found in and around the Penn Yan area.
Together, the duo visited manufacturing plants like Abtex and Ferro, artisan studios and even retail shops such as Pinckney’s Ace Hardware to document in photographs the elements in their natural or manufactured forms. The resulting images —with each name, two-letter scientific abbreviation, and a brief description of its characteristics and uses —are now on display in many storefront windows along Main Street, Penn Yan, effectively turning Main Street itself into an art gallery for “Elements of the Finger Lakes.”
Nearly 60 elements of the Periodic Table’s full 118 elements were found; the full collection of images can also be viewed at the Lightner Gallery at Lightner Library on the campus of Keuka College. An opening reception will be held from 4 – 5:30 p.m. at Milly’s Pantry, 19 Main Street on Wednesday, June 10. Milly’s is one of many local shops featuring works from the “Elements of the Finger Lakes.” The exhibit will continue through July on Main Street and through August on campus.
“The project really helps people understand what chemical elements are, where they come from, how we use them and where they are [found],” Longyear said. “I like the fact that it will bring science to the masses in a way that they can understand.”
According to Longyear, the “field trips” he and Robak took last fall to companies like Ferro or Coach and Equipment proved how common many of the elements truly are. Ferro, the former Transition Element Company (TransElCo), manufactures an array of pigments, powders used to make computing materials, polishing applications for lenses, polymers, plastics and more. Coach and Equipment produces small to mid-size transit buses using elements including lead (Pb), Fluorine (F), lithium (Li) and argon (Ar) in its engineering process.
At Ferro, workers take basic elements like carbon (C), titanium, (Ti) and tungsten (W), and refine them for an industrial use. So the up-close-and-personal views offered at Ferro for the exhibit educate participants beyond just a logo or company tagline, Longyear said.
“This is more than the sign on the front and [the product] that comes out the door. This is what’s in-between and that was really interesting,” he described.
According to Robak, a project such as this serves to merge science with the community. Not only will participants learn a little more about chemistry, but they’ll learn more about the community where they live and work too.
“The Periodic Table can be hard to relate to … but in its simplest sense, it’s a list of the essence of every material that we can touch, see or interact with in our daily lives,” Robak said, adding that many people may not realize just how many elements could be in their own homes, too.
“This project would not have happened without those willing to let us ask questions, give tours or shoot photography inside their businesses,” Robak said, noting that many company staffers actively tried to find elements in use or suggest others for Robak and Longyear to document. Community participation for the exhibit has also been high, Robak added, thanking the numerous business owners along Main Street who agreed to display the poster-size images in storefront windows or indoor displays. A trifold brochure will also be available at many participating businesses so pedestrians can learn about the project as they stroll Main Street.
Artisans such as Pete Knickerbocker of Spider’s Nest Pottery or Keuka College Professor Emeritus Dexter Benedict of Fireworks Foundry were also part of the exploration. Benedict sculpts works of bronze, using oxygen (O), aluminum (Al) and lots of copper (Cu) in the process. Meanwhile, Knickerbocker makes use of elements including cobalt (Co), iron (Fe), chromium (Cr), and also copper (Cu) in his pottery.
“I had no idea that a potter could tailor and design not only his or her own glazes, but the clay itself, and (Pete) was able to manipulate those elements in order to set himself apart in his field,” Longyear described.
While Longyear served as primary photographer, a few elements, such as hydrogen, posed a challenge to shoot because they can only be seen when reacting with another element, he said. In those cases, it was a challenge to “tell the story,” he said.
But Mother Nature also offered a few elements as well, which the duo incorporated into the project, including images of bones for calcium, the night sky (space) for hydrogen, and a sunset at Montezuma Wildlife Refuge to represent helium, Longyear explained.
“Every day we use elements from the earth. You can look at the Periodic Table and see a number and a name, but if you really dig into it, it’s really cool,” Longyear said.
An editorial by biology major Kelsey Morgan ’15
It is largely undisputed that advancements in science and technology are extremely important to life as we know it. However, with the way science and technology are represented in the media and popular culture, it can be difficult to distinguish between science and science fiction. Will the Ebola virus become an airborne super plague and kill us all? Are GMOs really safe? Should we be worried about climate change? And who can we trust to give us the answers?
The answer to this last question should be science, because it is designed to help us answer questions in a systematic, evidence-based way. Unfortunately, people often take a cynical attitude toward science, unfoundedly rejecting its discoveries. A Pew Study published in January reports that while people think science is a good thing, there is often a gap between scientists’ attitudes regarding hot-button issues and those of the general public. While a strong majority of scientists agree that genetically modified foods are generally safe to eat, global warming is a serious problem, and vaccines are safe, only a small part of the general public tends to agree. These gaps in understanding show that despite people reporting that they trust science, there is a large amount of disbelief and mistrust surrounding scientific consensus.
While there are many factors that determine whether or not a person accepts scientific evidence, general mistrust in science can be boiled down to three categories: religious and political affiliations, confirmation bias, and the need for an emotional appeal.
Religious beliefs or political associations can have a profound effect on whether or not a person accepts scientific principles. Some people refuse to accept theories such as the Big Bang and evolution because these theories go against religious doctrines. Politicians also likes to take sides regarding science, often debating issues when there aren’t even two different sides to the issue. For example, the original source of the idea that vaccines cause autism and other harm was an extremely flawed and unethical study that was later retracted. However, this idea gained momentum when it was supported by U.S. Rep. Dan Burton (R-Indiana). Burton and other public figures allowed the “debate” on the MMR to spread, which was a factor that led to a serious mistrust in vaccinations in general.
The “Badge of Membership” principle—membership is more about wanting to belong than what you believe— can help us understand how these affiliations shape our view of science. It’s like we are still in high school; no matter how old a person gets, he or she still feels the need to agree with his or her peers, and many times the need to fit in trumps science.
A study performed by Dan Kahan of Yale University found that understanding science results in polarization rather than consensus. This finding can be explained by confirmation bias. When people have an opinion about a scientific issue, showing them a collection of facts won’t change it. Shouting a bunch of complicated astrophysics and Darwinian natural selection theory at them isn’t likely to get them to believe in the Big Bang or evolution. Instead, people tend to pick out evidence that supports their preconceived notions.Anecdotal evidence that appeals to our emotions often holds more weight than facts, regardless of the source. We don’t like to rely on cause and effect because true causes can be hard to find and understand, and therefore we rely on people’s personal stories to come up with our own explanations and create meaning where there is none. A case in point: the causes of autism are not well understood, and science provides little reassurance, in terms of treatment, to parents of autistic children. Therefore, in spite of the understanding that vaccines do not cause autism, the public often turns to parents and grandparents who blame vaccines rather than trusting medical professionals because it gives them something to blame, too.
Life today depends heavily on complex science and technology that only a small group of experts can thoroughly understand, and it is therefore important that people trust and support these experts. While there is certainly reason to be skeptical when looking at new scientific findings, Science editor Marcia McNutt said it best in an interview for the March 2015 edition of National Geographic: “Everybody should be questioning… But then they should use the scientific method, or trust people using the scientific method, to decide which way they fall…”
Looking at science with skepticism is not the same as unwarranted distrust and rejection of consensus. In order for advancement in science to continue, the public must step away from scientific cynicism and put its trust in scientific consensus.
Editor’s Note: Kelsey Morgan ’15 of Lakeview, N.Y., holds a biology degree from Keuka College and has received a $28,000 fellowship stipend to attend Duke University Graduate School in the fall of 2015 to pursue a Ph.D. in chemistry. A research study she co-wrote with Dr. William Brown, assistant professor of environmental science and biology, was published in the Journal of American Animal Welfare Science (JAAWS) in the spring of 2015. She is one of three science majors featured in the spring 2015 edition of Keuka College Magazine as an “academic all-star” for earning the unique distinction of publishing in an academic journal as an undergraduate student.
Editor’s Note: Where can a Keuka College degree take you? This is the first in a series of snapshot profiles on members of Keuka’s Class of 2014.
Brian DelPino ‘14 of Oneida earned his B.A. in biochemistry and will be heading to graduate school at the Touro College of Osteopathic Medicine in New York City this fall.
DelPino’s time at Keuka College included competing on the men’s cross-country team where he logged top-five team finishes in five of seven meets, during his junior year. DelPino’s top finishes included running an 8K in 35:08.72 in 2013, and a 6K Invitational race in 29:02.59 in October 2012.
Indoors, DelPino made his mark in the sciences, and for a final Field Period™, he worked with Rebecca Evanicki ’14 and Professor of Chemistry Tom Carroll to set up new high-tech lab equipment and write instruction manuals for state-of-the-art machines added to the third-floor analysis lab in Jephson Science Center over winter break. The four Perkin-Elmer machines enable student researchers to identify unknown substances in minutes when it used to take hours on paper.
DelPino said the biggest benefit of his Keuka College education was the ability to “become close with my professors and have the opportunity to get help or academic advice when I needed it.”
Once in New York City, DelPino plans to study one year in the Touro biomedical sciences program then pursue a Doctor of Osteopathy degree, which he said is similar to an M.D. but based in a different philosophy. Many patients may not realize their doctor actually holds an osteopathy degree, he said.
“I would go there for four years and then apply for a residency position for another couple years of training. I could be a pediatrician, cardiologist, surgeon etc.,” DelPino said. “Ultimately, I would love to specialize in surgery but it is hard to tell if that’s what I will end up doing. In terms a residency, which is after medical school, I am not sure where I will go. It’s a whole process of applying to hospitals and depends on your grades and test scores in medical school, but hopefully, if I put in the same amount of work I have here [at Keuka College], I will get into a competitive residency position.”
Talk to Dr. Tom Carroll for just a few minutes about the new high-tech instruments in the third-floor analysis lab in Jephson Science Center and you get the sense the 30-year professor of chemistry at Keuka College is more excited than a kid on Christmas morning.
To the untrained eye, the four new Perkin-Elmer laboratory machines resemble something akin to desktop printer-copiers. But the machines are capable of the kind of data analysis a researcher can use when an unknown substance is handed over with the instructions “find out what this is and report back to me.” With one test on any of these machines, a student researcher could identify in minutes what used to take hours on paper. Carroll is thrilled students – and faculty – can now make regular use of the new equipment.
To biology major Rebecca Evanicki ’14, the new machines enable students to analyze unknown compounds in such a way that it’s like “solving a mystery,” she said.
Indeed, Associate Professor of Chemistry Andrew Robak is already planning to stage a fake crime scene in the organic chemistry lab next door later this spring. He’ll give the students in his organic chemistry class one day to collect evidence and they’ll spend the last few weeks of the semester in the analysis lab using the new machines to identify every substance, “like a CSI practice version,” he said, referring to the popular TV crime show.
It’s the kind of innovation that brings the student research at Jephson Science Center into a new era of digital learning, which is part of the College’s Long-Range Strategic Plan. Thanks to a $137,000 grant from Jephson Educational Trusts, the new machines were purchased and installed between semesters. They represent significant technology improvements that will enhance science coursework and research for students and faculty.
To formally recognize the new lab capabilities, the College will host its first-ever Innovation Celebration, set for 2-4 p.m., Friday, March 14, which is National Pi Day. In mathematics, Pi (represented by the Greek letter π) begins with the numbers 3.14159 and represents the ratio of the circumference of a circle to its diameter. Pi is infinite and has been calculated to over one trillion digits beyond its decimal point; contests to recite a portion of those digits are often part of the worldwide celebration. Keuka College will host its own Pi recitation contest, and guests can also take part in an unveiling ceremony, enjoy science-themed refreshments, and browse student work on display. Guided tours through the instrument lab will also be offered, and President Jorge L. Díaz-Herrera will give a videotaped message of congratulations.
Check out a unique digital timeline of stories and photos, marking moments of achievement in the College’s science history since the former Millspaugh Science Center was renamed the Jephson Science Center.
One machine, the High-Pressure Liquid Chromatograph (HPLC), carries liquids from glass bottles through thin plastic tubes, passing through several compartments for analysis. According to Robak, different compartments contain an oven, vacuum pump, solution tray, and detectors, respectively.
On the tabletop directly across from it sits another machine, the Gas Chromatograph-Mass Spectrometer (GC/MS or “GC – Mass Spec”). To put it simply, the GC separates mixtures into individual components, while the “mass spec” identifies separate fragments, so the scientist can determine what the molecules are, Carroll said. In scientific terms, this process is known as ionizing. The GC/MS features a rotating unit that can extract samples from a tray of up to 108 small vials at one time, conducting analysis as programmed by a small touch screen at the side.
Connected to the CG/MS is a new computer running high-performance software that converts the data readings of molecular ions into a bevy of colorful charts and graphs. Based on the peaks and plunges of a fragment’s chart, the computer searches a large digital library to find the closest match – all in a matter of seconds, Evanicki said. Without it, a student would have to calculate results by hand to narrow down what fragments might be present and then cross-check his or her shortlist of possibilities against a book to determine the answer, she said.
On another table against the wall, a smaller machine, the Fourier Transform Infrared Spectrometer (FTIR), contains an oval plate with a small diamond reflective element through which infrared light can pass. Connected to another computer running high-speed software, the FTIR is able to provide information about the identity of liquid or solid compounds, Carroll said.
The fourth machine, a Lambda-35, is a newer model of a UV spectrometer already in the lab. It uses visible and ultraviolet light to determine the absorption spectrum of a solution, which will show how much light it absorbs across a range of wavelengths, from visible to UV rays.
The GC/MS is Evanicki’s favorite because various tests on multiple samples can be run in one sitting without switching vials in the tray, she said. In addition, a student can run a series of different tests on just one sample.
“There are just so many different things you can do with it,” Evanicki said.
She should know. Evanicki spent the bulk of January alongside biochemistry major Brian DelPino ’14, setting up the new machines, conducting test runs and writing equipment usage manuals, all as part of their senior Field Periods™. Carroll defers to the duo with pride, dubbing their user guides “equipment manuals for dummies.”
“Step One: Turn the machine on,” he read aloud from a sheaf of typewritten instructions, before continuing tongue-in-cheek. “Step Two: If you have any questions or problems, contact Rebecca or Brian.”
On Wednesday, sophomores in Robak’s organic chemistry class took a sneak peek at the new equipment they were due to try out in their Thursday lab. About a dozen other students in Carroll’s Analytical Chemistry course will also run utilize the instrument lab this spring. Enthusiasm is running high, not just for the chance to use the machines this semester, but for the rest of their undergraduate studies.
“We’re all very excited about the new equipment and excited to learn how to use it – science is fun!” said biology major Heidi VanBuskirk ’16.

Turn the pages of Tipsy Magazine’s Summer 2013 edition and you’ll find the latest trends in high-fashion nail and manicure art.
Tipsy caters to salon owners, manicure artists and nail divas nationwide who turn to the 9×12 glossy for up-to-the-minute articles and photos on polish products, fingertip designs and the edgy nail jewelry that celebs like Lady Gaga have catapulted to fame. Its touted trends take the traditional acrylic manicure (Only one shade of polish? Puh-lease!) to a color-and-jewel-crazed, punk rock-level.
Which is why it should come as no surprise that Dr. Andrew Robak, associate professor of chemistry, has landed in the pages of a Tipsy article. Robak, who holds a Ph.D. in organic chemistry, has self-described “wacky interests” in chemistry or science as art. His expertise was sought by writer Erin Hart, who started her own design business, Nail Pop LLC, just over a year ago, working on location doing photo shoots, nail parties and fashion shows. Hart endured a nasty chemical burn after she tried to mix fake gold leaf, a decorative metallic, with nail glue to create her own quick-dry polish.
“The gold leaf is so popular right now because it just looks so decadent and when you’re having your nails done, you want to go all out,” said Hart, noting the element comes in either sheets or flake form and can be found at craft or art stores. Hart said she was at home with a friend, experimenting with the fake gold leaf by gluing a big piece to the tip of her finger when “decadent” turned into “drama.”
“The burning started immediately and as I was trying to peel away the [gold] leaf, my skin blistered and came off. I didn’t lose too much skin, about the size of an eraser head, but boy did it hurt!” Hart said, adding it reminded her of burning her finger on a marshmallow stick when she was a kid.
“It took about a week for it to heal using your standard first aid burn care.”
According to Hart, staying ahead of the trends in nail art happens most often by experimenting with different materials, so to best inform other nail artists of any potentially dangerous combinations, she packed up the gold leaf and glue and shipped them to Robak for a thorough chemical analysis and explanation. The two are cousins and Hart had no problem asking for a family favor, she said.
“He was the first person I thought to call after I burned myself and I knew he’d be able to figure it out, which he did immediately after receiving the samples I sent,” Hart said. “I was really impressed with how quickly he was able to compose an explanation that I could actually understand.”
It turns out the fake gold leaf flakes are essentially a combination of tin, zinc and shiny copper. The tin and zinc prevent the copper from tarnishing, Robak informed Hart. The nail glue, known as ethyl cyanoacrylate, is a polymer that will cure, or dry rapidly, once exposed to small amounts of moisture in the air or on surfaces. What non-scientists like Hart think of as “glue drying” is really the substance changing from liquid to solid form, Robak said.
Ordinarily, a tiny, almost imperceptible amount of heat is released as the glue hardens, but when mixed with the fake gold leaf, the tin and zinc become catalysts, speeding up the process such that there is an excess of heat energy, Hart learned. The gold-glue mixture can’t hold as much heat energy as the liquid glue alone, and not only causes chemical burns but can even produce small tufts of smoke, Robak informed Hart.
So what’s a nail artist to do?
Well, one solution would be to use real gold, Robak suggested, noting the pure element is one of the least reactive substances and won’t require tin to protect it from tarnish. According to the New York Mercantile reported on CNNMoney.com, real gold is currently retailing for about $1,391 an ounce.
If you can’t afford that option but seeing a shiny, metallic gleam at the end of your fingertips is still a must-have, then switching to a simple, clear polish and mixing that with the fake gold leaf will produce the same ritzy look without the Ritz-Carlton price tag. The clear nail polish won’t dry as fast as the glue, but it won’t create an exothermic reaction either, Robak advised.
And that was the advice Hart chose to share with fellow Tipsy readers after she came across a call for submissions for upcoming issues. As it turns out, her unexpected science revelation became her first “big” article for a magazine.
“I’m hoping to do more writing in the future, but I think this first attempt went pretty well,” Hart said, noting she called her cousin for permission to include him in the article. “Most of what you mix with nail glue won’t create an exothermic reaction, but I’ve also experienced heat from nail glue when it comes in contact with cotton fibers. It’s something I’ll need Dr. Robak’s expertise to explain further.”
