  • Designing glass with non-dispersive stress-optic response 

    J. Galbraith, J.W. Zwanziger, Designing glass with non-dispersive stress-optic response, Journal of Non-Crystalline Solids, Volume 433, 1 February 2016, Pages 82-86, ISSN 0022-3093, http://dx.doi.org/10.1016/j.jnoncrysol.2015.11.027
    The dispersion of the stress-optic response of a series of barium and lead phosphate glasses is measured using an ellipsometric method. It is found that the barium glasses display consistently positive dispersion with ...

  • Mechanical–Structural Investigation of Ion-Exchanged Lithium Silicate Glass using Micro-Raman Spectroscopy 

    Mechanical–Structural Investigation of Ion-Exchanged Lithium Silicate Glass using Micro-Raman Spectroscopy Courtney Calahoo, J. W. Zwanziger, and Ian S. Butler The Journal of Physical Chemistry C 2016 120 (13), 7213-7232 DOI: 10.1021/acs.jpcc.6b01720
    Micro-Raman spectroscopy was used to determine the structural modifications occurring in a simple ion-exchanged glass. The base lithium silicate composition 30Li2O–70SiO2 was studied as it underwent ion exchange, Li+ ↔ K+, ...

  • Nanoindentation Study of the Surface of Ion-Exchanged Lithium Silicate Glass 

    Nanoindentation Study of the Surface of Ion-Exchanged Lithium Silicate Glass Courtney Calahoo, Xiaofang Zhang, and J. W. Zwanziger The Journal of Physical Chemistry C 2016 120 (10), 5585-5598 DOI: 10.1021/acs.jpcc.6b00733
    Variations in mechanical properties (stiffness and hardness) were measured as a function of case depth in ion-exchange glasses using nanoindentation. A simple silicate composition, 30Li2O–70Si2O, was exchanged (Li+ ↔ K+) ...
