With the increasing demand for high temperature-resistant heat insulation materials for hypersonic vehicles, carbon foam has been studied extensively, and its mechanical and thermal properties have been fully researched, but the oxidation behavior of carbon foams during service and the change in their properties after oxidation are rarely studied. This paper studied the relationship between both mechanical and thermal properties and oxidation degree of two kinds of foams, coal-based carbon foam and antioxidant coal-based carbon foam with chemical vapor deposition of SiC particles. The variation trend for the two kinds of foam was the same. When the oxidation degree was less than 15%, the compression modulus and strength weakened with the increase in weight loss rate, but the thermal conductivity decreased with the increase in weight loss rate, which was a favorable influence for the thermal protection system. The mechanical and thermal properties had a linear relationship with the weight loss rate, but the slope was different between 0% to 10% and 10% to 15%. The microscopic mechanism of these changes was also analyzed.

“…The thermal contact resistance between the thin films (SiN x /Si, Au/Cr/SiN x ) are on the order of 10 -8 m 2 K/W [33,34], and are insignificant compared to the resistance of the adhesive tape (∼ 10 -3 m 2 K/W) itself. The contact resistance on either side of the adhesive tape are also assumed to be negligible [35].…”

Measuring temperatures within a biological cell requires a sensor with small thermal mass and microscale or smaller size that is electrically and chemically inert to the cell's environment, and is thermally isolated from the surroundings. We investigate how such requirements can be satisfied in a microscale thermocouple probe that is fabricated using the techniques of silicon-based microelectromechanical systems. Previous reports of invasive probes lacked either the required spatial resolution (< 5 µm) or response time (< 4 ms). Here, we report 1 µm thick silicon nitride supported probes with a 5 µm tip that has a response time of 32 µs. These figures enable future transient thermometry of cell organelles. To reduce calibration errors, we devise an on-chip calibration in a vacuum cryostat. We find that the accuracy of our measurements is ±54 mK for 300 ± 10 K. This work paves the way toward future thermometry at a subcellular level.

Future tracking detectors, such as those under development for the High Luminosity LHC, will require mechanical structures employing novel materials to reduce mass while providing excellent strength, thermal conductivity, and radiation tolerance. Adhesion methods for such materials are under study at present. This paper demonstrates the use of reactive bonding film as an adhesion method for bonding carbon foam.
