Highly Stable Glasses of cis-Decalin and cis/trans-Decalin Mixtures
Katherine R. Whitaker, Daniel J. Scifo, M. D. Ediger +2
In situ AC nanocalorimetry was used to measure the reversing heat capacity of vapor-deposited glasses of decahydronaphthalene (decalin). Glasses with low heat capacity and high kin…
A molecular perspective on the yield and flow of polymer glasses: The role of enhanced segmental dynamics during active deformation
M. D. Ediger, Kelly Hebert
The mechanical properties of polymer glasses are often critical in determining the best material for a particular application. Extremely stiff materials (high modulus) may be impor…
Rejuvenation versus overaging: The effect of cyclic loading/unloading on the segmental dynamics of PMMA glasses
Trevor Bennin, Enran Xing, Josh Ricci +1
The acceleration of structural relaxation or physical aging by deformation, known as overaging, has been reported in experiments and simulations of polymer and colloid glasses, and…
Controlling Structure and Properties of Vapor-Deposited Glasses of Organic Semiconductors: Recent Advances and Challenges
Kushal Bagchi, MD Ediger
The last decade has seen great progress in manipulating the structure of vapor-deposited glasses of organic semiconductors. By varying the substrate temperature during deposition,…
Physical aging of glasses of an organic semiconductor
Shinian Cheng, Kritika Jha, Zijian Wang +5
All glasses, including organic semiconductor glasses, are non-equilibrium materials whose properties will change with time. This physical aging process is poorly understood for org…
Limited surface mobility inhibits stable glass formation for 2-ethyl-1-hexanol
M. Tylinski, M. S. Beasley, Y. Z. Chua +2
Previous work has shown that vapor-deposition can prepare organic glasses with extremely high kinetic stabilities and other properties that would be expected from liquid-cooled gla…
