    • An isothermal titration micro calorimetry (ITC) system (300), comprising: a microcalorimeter (20), an automatic pipette assembly (30), a pipette translation unit (310) and a wash station.. The microcalorimeter (20) has a sample cell (50) and a reference cell (40), the sample cell (50) accessible via a sample cell stem (180) and the reference cell accessible via a reference cell stem (170). The automatic pipette assembly (30) comprise a syringe (200) with a titration needle (210) arranged to be inserted into the sample cell (50) for supplying titrant and a fill port (500) at an upper section of the syringe (200), providing fluidic contact with the syringe cavity when the plunger (230) is positioned above the fill port (500). The pipette assembly (30) also comprises an activator (220) for driving a plunger (230) in the syringe (200). The pipette translation unit (310) comprises a pipette arm (380) that is supported for rotation about an axis (A), supports the pipette assembly (30) at its other end and is further arranged to move the pipette assembly vertically. The pipette translation unit (310) is arranged to place the pipette assembly (30) in position for titration, washing and filling operations. The wash station is for the titrant needle (210).

    • A method of characterizing phase transformations of a shape memory material specimen entails recording data from the specimen during heating and cooling. The temperature of the specimen is changed in a first direction to a first temperature sufficient to define a first inflection and a second inflection in the data being recorded. The temperature of the specimen is changed in a second direction to a second temperature sufficient to define a third inflection in the data. The third inflection is formed by overlapping primary and secondary sub-inflections. The temperature of the specimen is changed in the first direction to a third temperature sufficient to define the first inflection but not sufficient to define the second inflection. The temperature of the specimen is then changed in the second direction to a fourth temperature sufficient to define the secondary sub-inflection in the data being recorded.
    • 表征形状记忆材料样品的相变的方法需要在加热和冷却期间从样品记录数据。 样本的温度在第一方向上变化到足以限定正在记录的数据中的第一拐点和第二拐点的第一温度。 样本的温度在第二方向上变化到足以限定数据中的第三个拐点的第二温度。 第三个拐点是通过重叠的次级次级变换形成的。 样本的温度在第一方向上变化到足以限定第一拐点但不足以限定第二拐点的第三温度。 然后将样本的温度在第二方向上改变到足以限定正在记录的数据中的次级变形的第四温度。
