(Physical review B, 2018-01)
    We report the observation of bunching of monoatomic steps on vicinal W(110) surfaces induced by step-up or step-down currents across the steps. Measurements reveal that the size-scaling exponent γ , connecting the maximal ...
  • Mektepbayeva, Damel; Alibek, Kenneth; Atinbayeva, N.; Irving, S; Zhaisanbayeva, B; Mussurova, S; Mussakhan, S (Austin Journal of Cancer and Clinical Research, 2015-08)
    Melatonin (N-acetyl-5-methoxytryptamine, MLT) is a naturally occurring hormone secreted by the pineal gland. Clinical evidence suggests that MLT may have a possible role in the treatment of cancer, where MLT presents many ...
