The upcoming computing colloquies will help campus researchers identify and make the most of the diverse array of campus computing resources available at the University. All faculty, students and staff conducting, planning or supporting research activities at the University are invited to the sessions.

Teng Zhang, an assistant professor in mechanical and aerospace engineering in the College of Engineering and Computer Science, will present “Topology design in soft structures by controlling surface wrinkles.” Materials like tissues and gels are typical soft structures that have low elastic modulus and thus are easily deformed. Structures like surface topology change due to wrinkle instability are widely found in these soft materials and have been utilized to design smart adhesives, anti-biofouling, and in this talk, Zhang will demonstrate the principle of topology design via examples of controllable surface wrinkles. He will present a systematic study of the origin of the hexagonal wrinkle patterns observed in the experiments of bi-layer soft materials via large-scale simulations. Nonlinear evolution of surface wrinkle patterns and effect of curvatures will also be discussed.
Tuesday, April 17. 12:30-2 p.m. Katzer Collaboratory, 347 Hinds Hall. Lunch will be included. Please register by Thursday, April 12.
Timothy Korter, professor and chair of the Department of Chemistry in the College of Arts and Sciences, will present “Nondestructive and Noninvasive Identification of Historical Pigments.” Pigments found in modern art objects are often completely unlike those found in antiquity. The detection and identification of exact pigment components are critical to art restoration and conservation and important to revealing the provenance and authenticity of art pieces. Nondestructive testing is required, and noninvasive approaches are greatly preferred. Low-frequency vibrational spectroscopy is an emerging non-contact method for establishing the unique spectral fingerprints of pigments in art objects. Korter’s laboratory uses terahertz time-domain spectroscopy (THz-TDS) and low-frequency Raman spectroscopy (LFRS), both incredibly sensitive to the chemical identities and three-dimensional solid-state packing arrangements of pigments. The complete understanding of the observed spectral fingerprints is a continuing challenge due to the complexity of the samples. His team utilizes ab initio quantum mechanical simulations to simulate the structures and vibrational motions of both inorganic and organic materials. This enables complete assignment of the spectra and thereby unambiguous identification of pigment species. This work consists of rigorous calculations involving hundreds of atoms. The efficient parallel computing environment at Syracuse University makes it possible.
Wednesday, April 25. 12:30-2:00 p.m. Katzer Collaboratory, 347 Hinds Hall. Lunch will be included. Please register by Friday, April 20.
