    • Application of in-situ nano-scanning calorimetry and X-ray diffraction to characterize Ni–Ti–Hf high-temperature shape memory alloys 

      McCluskey, Patrick; Xiao, Kechao; Gregoire, John M.; Dale, Darren; Vlassak, Joost J. (Elsevier BV, 2015)
      Combinatorial nanocalorimetry and synchrotron x-ray diffraction were combined to study the martensite-austenite (M-A) phase transformation behavior of Ni-Ti-Hf shape memory alloys. A thin-film library of Ni-Ti-Hf samples ...

    • Assured Safety Drill With Bi-Stable Bit Retraction Mechanism 

      Loschak, Paul; Xiao, Kechao; Pei, Hao; Kesner, Samuel Benjamin; Thomas, Ajith; Walsh, Conor (ASME, 2013-08-04)
      A handheld, portable cranial drilling tool for safely creating holes in the skull without damaging brain tissue is presented. Such a device is essential for neurosurgeons and mid-level practitioners treating patients with ...

    • A Scanning AC Calorimetry Technique for the Analysis of Nano-Scale Quantities of Materials 

      Xiao, Kechao; Gregoire, John M.; McCluskey, Patrick J.; Vlassak, Joost J. (American Institute of Physics, 2012)
      We present a scanning AC nanocalorimetry method that enables calorimetry measurements at heating and cooling rates that vary from isothermal to \(2×10^3 K/s\), thus bridging the gap between traditional scanning calorimetry ...

    • Scanning AC Nanocalorimetry and Its Applications 

      Xiao, Kechao (2015-06-29)
      This thesis presents an AC nanocalorimetry technique that enables calorimetry measurements on very small quantities of materials over a wide range of scanning rates (from isothermal to 3×10^3 K/s), temperatures (up to 1200 ...

    • Scanning AC nanocalorimetry combined with in-situ x-ray diffraction 

      Xiao, Kechao; Gregoire, John M.; McCluskey, Patrick; Dale, Darren; Vlassak, Joost J. (American Institute of Physics (AIP), 2013)
      Micromachined nanocalorimetry sensors have shown excellent performance for high-temperature and high-scanning rate calorimetry measurements. Here, we combine scanning AC nanocalorimetry with in-situ x-ray diffraction (XRD) ...

    • Scanning AC Nanocalorimetry Study of Zr/B Reactive Multilayers 

      Lee, Dongwoo; Sim, Gi-dong; Xiao, Kechao; Seok Choi, Yong; Vlassak, Joost J. (American Institute of Physics, 2013)
      The reaction of Zr/B multilayers with a 50 nm modulation period has been studied using scanning AC nanocalorimetry at a heating rate of approximately \(10^3 K/s\). We describe a data reduction algorithm to determine the ...
