Temperature stability of intersubband transitions in AlN/GaN quantum wells

open access: yes, 2010
Temperature dependence of intersubband transitions in AlN/GaN multiple quantum wells grown with molecular beam epitaxy is investigated both by absorption studies at different temperatures and modeling of conduction-band electrons.

Simultaneous achievement of large strain, low hysteresis, and high-temperature stability in textured BT-based piezoelectric ceramics

open access: yesJournal of Advanced Ceramics
BaTiO3 (BT)-based piezoceramics with large temperature-stable strains and low hysteresis are urgently needed for high-precision actuators because of increasing environmental problems. Here, tetragonal [001]c-textured (Ba0.98Ca0.02)(Ti0.96Sn0.04)O3 (BCTS)

Low temperature offers better foam stability

open access: yesJournal of Cosmetic Dermatology
AbstractBackgroundThe foam's structural longevity, linked to the effectiveness of sclerotherapy, depends on preparation conditions. The factors enhancing the treatment's effectiveness and efficacy are still under discussion.MethodsWe conducted an in vitro preclinical research, which included 144 independent trials.

Finite-temperature trapped dipolar Bose gas

open access: yes, 2012
We develop a finite temperature Hartree theory for the trapped dipolar Bose gas. We use this theory to study thermal effects on the mechanical stability of the system and density oscillating condensate states.

Sensing disks for slug-type calorimeters have higher temperature stability [PDF]

open access: yes, 1967
Graphite sensing disk for slug-type radiation calorimeters exhibits better performance at high temperatures than copper and nickel disks. The graphite is heat-soaked to stabilize its emittance and the thermocouple is protected from the graphite so ...

Integrating Multiple Hierarchical Parameters to Achieve the Self-Compensation of Scale Factor in a Micro-Electromechanical System Gyroscope

open access: yesMicromachines
The scale factor of thermal sensitivity serves as a crucial performance metric for micro-electromechanical system (MEMS) gyroscopes, and is commonly employed to assess the temperature stability of inertial sensors. To improve the temperature stability of
