Discovering Periodic Table Elements Throughout Penn Yan

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.

Dr. Robak, left and Phil Longyear '14, right, on Main Street, Penn Yan.

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.

A welder at Coach and Equipment works with special tools, producing plasma from the reaction of (O) oxygen with the fuel in the tool (most likely acetylene gas).

“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.

Dr. Robak examines a brick near the kiln at Peter Knickerbocker's Spider's Nest Pottery Studio.

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.

Light, Computers, Science!

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.

The HPLC may look like a stack of drawers on a desktop printer, but it can analyze liquids in multiple ways.

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.

A computer connected to the GC/MS, running high-performance software, analyzes in minutes what used to take hours.

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.

Evanicki '14 examines the tray of the GC/MS, which can hold up to 108 vials of solution or compound for analysis.

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.

Josh Makin’s Field Period™ Confirms Career Goals

Sophomore Josh Makin (Lethbridge, Alberta/Catholic Central) has been instrumental in the successes of the Keuka College men’s volleyball team.

In 2013, Keuka’s first year with a team, Makin, an outside hitter, earned second-team All-North Eastern Athletic Conference (NEAC) honors as the Storm captured the NEAC postseason championship.

As a talented student-athlete, Makin relies on athletic trainer Jeff Bray and assistant athletic trainer Gabrielle Lorusso to keep him healthy and on the court, despite the assorted nicks and bruises that occur during the volleyball season.

During the January Field Period™, Makin landed a joint Field Period™ with Rebound Health Center in Lethbridge, Alberta and Ocean Physical Therapy in San Clemente, Calif.

His appreciation for physical therapy started before Makin arrived on campus. When he was 17, Makin tore his anterior cruciate ligament (ACL) and had reconstructive surgery before enduring a grueling, six-month rehabilitation.

Recognizing the important role physical therapists play in not only athletics, but in day-to-day life, Makin, a biology major, decided he wanted to become a physical therapist once he graduates from Keuka.

His latest Field Period™ only reaffirmed his passion for physical therapy. (more…)

A Tale of Two Juniors

It’s a cold day in Buffalo, typical for this industrial city, which is dusted with a fine coat of snow. Traversing the numerous buildings and animal habitats at the Buffalo Zoo, but sporting warm and cheerful smiles, are Ashley Hager and Megan Hilsdorf, junior biochemistry majors at Keuka College.

Both put in 8-hour-a-day, 6-day work weeks for three weeks in January to conduct 140-hour, Field Period internships at the zoo. While Hager spent most of her time in the Reptile House, working in the Hellbendar (salamander) acquatics lab, Hilsdorf worked with primates, birds and other animals in the M&T Rainforest Falls exhibit. Both were exposed to sections of the zoo the public never sees,  such as where specialized meals are prepared for each exhibit, animals receive any needed veterinary care, and babies are are kept until they are old enough to venture out into the display habitats.

Thanks to a relative of Hilsdorf’s who offered use of his Buffalo apartment for three weeks when he wasn’t going to be there, both girls were able to stay in the city and commute to the zoo each day for the internship, which is an annual part of every Keuka student’s graduation requirements.

“They’re so short-staffed, and they told us we’ve been a big help,” said Hager.
