Thermal Behavior of Biaxial Piezoelectric MEMS-Scanners [PDF]
Sensors, 2023 This paper presents the thermal behavior of non-resonant (quasi-static) piezoelectric biaxial MEMS scanners with Bragg reflectors. These scanners were developed for LIDAR (LIght Detection And Ranging) applications using a pulsed 1550 nm laser with an ...

Thermal Resonance and Cell Behavior [PDF]
Entropy, 2020 From a thermodynamic point of view, living cell life is no more than a cyclic process. It starts with the newly separated daughter cells and restarts when the next generations grow as free entities. During this cycle, the cell changes its entropy. In cancer, the growth control is damaged.

Fatigue-creep behaviors of Ni–Fe based superalloy under various testing conditions
Journal of Materials Research and Technology, 2021 The fatigue-creep properties of Ni–Fe based superalloy with varying strain amplitude, temperature and holding duration are studied in ambient air. The results demonstrated that the number of cycles decreases greatly with increasing strain amplitude from ...

Universal Behavior of the Thermal Hall Conductivity [PDF]
Physical Review Letters, 2020 We report theoretical and experimental analyses of the thermal Hall conductivity in correlated systems. For both fermionic and bosonic excitations with nontrivial topology, we show that at "intermediate" temperatures, the thermal Hall conductivity exhibits an unexpected universal scaling with a simple exponential form.

Thermal behavior of polytriazole films: A thermal analysis study [PDF]
Journal of Polymer Science Part A: Polymer Chemistry, 1989 AbstractThe thermal behavior of poly(1,3‐phenyl‐1,4‐phenyl)‐4‐phenyl‐1,2,4‐triazole has been investigated using different scanning calorimetry (DSC) and thermogravimetry (TG). Processes are studied for this thermally stable polymer that take place between 200 and 500°C. While the polycondensation reaction product in powder from appeared to be partially
