Development of an advanced nanocalorimetry system for material characterization

Chip-scale calorimeters: Potential uses in chemical engineering

“…Before performing experiments, the RTDs were annealed and calibrated against an external and commercially available two-wire thin-film RTD (F3105 from Omega), by placing the device and the reference RTD in an oven and recording the resistance measurements of the RTDs as a function of the temperature inside the oven when it was cooled down slowly (Liu, Ugaz, Rogers, Sam Mannan, & Saraf, 2005). The external RTD was glued directly to the surface of the calorimeter to obtain more accurate calibration results.…”

“…The reduced sample required by chip-scale calorimeters (nano-or micro-grams depending on the device sensitivity) gives a competitive advantage to these calorimeters because highly energetic materials can be tested in an inherently safer way. Consequently, it is feasible to employ handheld calorimeters for the screening and detection of highly energetic substances in security applications (Bannister et al, 2002;Liu et al, 2005Liu et al, , 2007Piazzon, Rosenthal, Bondar, Spitzer, & Ivanov, 2010;Zuck et al, 2008). A simple test in a scanning calorimeter can reveal whether a sample can represent a thermal hazard.…”

Review of MEMS differential scanning calorimetry for biomolecular study

“…To achieve high sensitivity, it is essential to increase the thermal insulation of the system which means minimize the thermal conductance G. In general, G 0 is small enough to be neglected then we can have Eq. (2) [26]:…”

“…In such case, additional adhesion layer is needed to increase the adhesion strength between the microfluidic chamber and the polymer membrane [53]. Figure 7 [26,48] shows two examples of the microfluidic system for MEMS calorimeters. In Fig.…”

Recent Advances in Trace Explosives Detection Instrumentation

“…They also used a similar device to measure the desorption characteristics of various explosives and common inerts [82]. Liu et al, are developing a nanocalorimetry system using a microreactor for application to rapid screening of energetic materials at low cost [83].…”
