  • Why is there no low-temperature phase transition in NaOH? 

    Reproduced from Bessonette, PWR, and MA White. 1999. "Why is there no low-temperature phase transition in NaOH?." Journal of Chemical Physics 110(8): 3919-3925, with the permission of AIP Publishing.
    Although NaOH and NaOD exhibit parallel polymorphism at high temperatures, NaOD exhibits a low-temperature phase transition to a hydrogen-bonded antiferroelectric phase and no comparable transition has been found in NaOH. ...

  • X-ray absorption spectroscopy studies of local structure and electronic properties of NaxSi136 (0 < x < 24) clathrates 

    Ritchie, Andrew D., Mark A. MacDonald, Peng Zhang, Mary Anne White, et al. 2010. "X-ray absorption spectroscopy studies of local structure and electronic properties of NaxSi136 (0 < x < 24) clathrates." Physical Review B 82(15): 155207-155207. Copyright © 2010 American Physical Society.
    We have probed both the local structure and the electronic properties of Na-containing type II Si clathrates by x-ray absorption spectroscopy. The near-edge region of the spectrum is particularly sensitive to the local ...
