Journal ArticleDOI
Distinguishing between calcites formed by different mechanisms using infrared spectrometry: archaeological applications
Lior Regev,Kristin M. Poduska,Lia Addadi,Steve Weiner,Elisabetta Boaretto,Elisabetta Boaretto +5 more
TL;DR: In this article, the authors exploit differences in the infrared spectra of geogenic, biogenic and pyrogenic calcites for the identification of each calcite type, which can assist in distinguishing between the various calcites, and provide insights into homogeneity and preservation state of the calcitic materials in question.
Journal ArticleDOI
Roughness effects on contact angle measurements
Bernard Ryan,Kristin M. Poduska +1 more
TL;DR: In this article, a simple and economical procedure was developed to demonstrate the effects of roughness and wetting fraction on the equilibrium contact angles of liquid droplets on solid surfaces, which can facilitate assessments of changes in true surface area due to surface roughening, as well as changes in the fractional contact areas of the water droplets, due to the formation of air pockets between the rough surface and the droplet.
Journal ArticleDOI
Decoupling Local Disorder and Optical Effects in Infrared Spectra: Differentiating Between Calcites with Different Origins
Kristin M. Poduska,Lior Regev,Elisabetta Boaretto,Lia Addadi,Steve Weiner,Leeor Kronik,Stefano Curtarolo,Stefano Curtarolo +7 more
TL;DR: Infrared spectral peak broadening due to atomic disorder and narrowing due to particle-size-related optical absorption effects can be decoupled experimentally and theoretically and provides a powerful diagnostic tool for archaeology, geology, and materials/biomaterials science.
Journal ArticleDOI
Linking crystal structure with temperature-sensitive vibrational modes in calcium carbonate minerals
Ben Xu,Kristin M. Poduska +1 more
TL;DR: The results suggest that studies of packing arrangements could provide a generalizable approach to identify the most diagnostic vibrational modes for tracking either temperature-dependent or crystallinity-related effects in IR-active solids.
Journal ArticleDOI
Dynamics, crystallization and structures in colloid spin coating
TL;DR: In this article, an overview of theoretical and experimental studies of spin coating of colloidal suspensions is presented, and the dynamics of the spin coating process is discussed first, and insights from both theory and experiment are presented.
