    • Annealing and Tempering for Sampling and Counting 

      Bhatnagar, Nayantara (Georgia Institute of Technology, 2007-07-09)
      The Markov Chain Monte Carlo (MCMC) method has been widely used in practice since the 1950's in areas such as biology, statistics, and physics. However, it is only in the last few decades that powerful techniques for ...
    • Controlling the crystallization and magnetic properties of melt-spun Pr₂Fe₁₄B/α Fe nanocomposites by Joule heating 

      Jin, Z. Q.; Cui, B. Z.; Liu, J. Ping; Ding, Yong; Wang, Z. L. (Zhong Lin); Thadhani, Naresh N. (Georgia Institute of TechnologyAmerican Institute of Physics, 2004-05-12)
      Pr₂Fe₁₄B/α Fe based nanocomposites have been prepared through crystallization of melt-spun amorphous Pr₇Tb₁Fe₈₅Nb ₀.₅ Zr ₀.₅ B₆ ribbons by means of ac Joule heating while simultaneously monitoring room-temperature electrical ...
    • Cyclic Behavior of Superelastic Nickel-Titanium and Nickel-Titanium-Chromium Shape Memory Alloys 

      Barbero Bernal, Laura Isabel (Georgia Institute of Technology, 2004-12-02)
      Shape memory alloys (SMAs) are a class of alloys that display the unique ability to undergo nonlinear deformations and return to their original shape when heat is applied or the stress causing the deformation is removed. ...
    • Effect of heat and plasma treatments on the electrical and optical properties of colloidal indium tin oxide films 

      Joshi, Salil Mohan (Georgia Institute of Technology, 2013-07-08)
      The research presented in this dissertation explores the possibility of using colloidal indium tin oxide (ITO) nanoparticle solutions to direct write transparent conducting coatings (TCCs), as an alternative route for TCC ...
    • Encapsulation of pentacene/C₆₀ organic solar cells with Al₂O₃ deposited by atomic layer deposition 

      Potscavage, William J., Jr.; Yoo, SeungHyup; Domercq, Benoit; Kippelen, Bernard (Georgia Institute of TechnologyAmerican Institute of Physics, 2007-06)
      Organic solar cells based on pentacene/C₆₀ heterojunctions were encapsulated using a 200-nm-thick film of Al₂O₃ deposited by atomic layer deposition (ALD). Encapsulated devices maintained power conversion efficiency after ...
    • Exchange-coupled FePt nanoparticle assembly 

      Zeng, Hao; Sun, Shouheng; Vedantam, T. S.; Dai, Z. R.; Liu, J. Ping; Wang, Z. L. (Zhong Lin) (Georgia Institute of TechnologyAmerican Institute of Physics, 2002-04-08)
      We have produced exchange-coupled FePt nanoparticle assemblies by chemical synthesis and subsequent thermal annealing. As the interparticle distances decrease by tuning the annealing conditions, interparticle interactions ...
