Chem Students Publish, Present and Bring Home the Gold

Proudly representing Hofstra at the 19th annual Chemistry Challenge at Queensborough Community College (QCC): Andrew Ko ’19, Nicole Khouryawad ’20, Gianna Kroening ’19, Joseph Mancuso ’22, Matthew Saleem ‘19, and David Shaker ’21 with Professor Ronald D’Amelia.

This spring Hofstra chemistry students presented research at national and regional conferences and medaled at an academic competition.

Students studying chemistry, biochemistry and forensic science traveled with Professors Ronald D’Amelia and Nanette Wachter-Jurcsak to the 257th meeting of the National American Chemical Society in Orlando, Florida. Students who presented research included Madeline Currie ‘20, Nicole Homburger ‘19, Mathusa Lakuleswaran ’20, Joseph Mancuso ‘22, Morgan Morrill ‘19, Hardler Servius ‘20, Sunaldeep Singh ‘20, and Haley Tarbox ‘19.

Examples of their research included “The Analysis of Copolymers and Blends of Polyvinyl Pyrrolidone (PVP) and Polyvinyl Acetate (PVAc)”; “Synthesis of Functionalized Polysilalkylene Siloxanes (Silicone) Monomers by Hydrosilylation”; and “The Compositional Analysis of Short Chain Fatty Acid Benzyl Esters Mixtures by NMR.”

Mancuso, Servius, Singh, and Tarbox also presented their work at the 67th New York Undergraduate Research Symposium (URS) at CUNY Queens College in Flushing, New York. Professor D’Amelia and Associate Chemistry Professor Scott Lefurgy were there providing professional and moral support.

Bronze medal winners David Shaker, Nicole Khouryawad, and Joseph Mancuso.

Teams of Hofstra students placed first and third at the 19th annual Chemistry Challenge at Queensborough Community College (QCC). The Chemistry Challenge is a quiz-style competition presented by the Long Island subsection of the American Chemical Society and sponsored by QCC-Student Affiliates of American Chemical Society. Matthew Saleem, Andrew Ko, and Gianna Kroening – all Class of 2019 – were members of the team that won the gold medal. First-time competitors Joseph Mancuso ‘22, David Shaker ‘21 and Nicole Khouryawad ‘20 placed an impressive third in the competition.

The challenge features a multiple choice test covering general and organic chemistry topics. Students representing area colleges work in teams and enter their answers using clickers. There are winners for four-year and two-year colleges.

Additionally, biochemistry major Joseph Mancuso worked with faculty on two articles that were published in academic journals. He collaborated with Drs. D’Amelia and Wachter on “Application of Quantitative Proton Nuclear Magnetic Resonance Spectroscopy for the Compositional Analysis of Short Chain Fatty Acid Benzyl Ester Mixtures.” Their research was published in the World Journal of Chemical Education.

Mancuso worked with Chemistry Department Chair William Nirode and Dr. D’Amelia on “The Characterization of Poly n-Vinyl Pyrrolidone-Polyvinyl Acetate (PVP-PVAc) Copolymers and Blends by Nuclear Magnetic Resonance Spectroscopy, Fourier Transform Infrared Spectroscopy, and Elemental Analysis.” That piece was published in the Journal of Polymer and Biopolymer Physics Chemistry.
