Direct Silyl Ether Metathesis for Vitrimers with Exceptional Thermal Stability.

Journal of the American Chemical Society, 2019
Vitrimers are a new class of polymeric materials that simulta-neously offer the desired physical properties of thermosets and malleability/reprocessability of thermoplastics. Despite significant progress being made in the field of vitrimers, there exists

Thermal stability of HoMnO3 [PDF]

Bulletin of the Russian Academy of Sciences: Physics, 2010
The low-oxygen limit of the homogeneity range of HoMnO3, which dissociates according to the reaction HoMnO3 = 1/2Ho2O3 + MnO + 1/4O2 in the temperature range 987–1160 K, was established by the static method. The temperature dependences of the equilibrium oxygen pressure, the change in the Gibbs free energy, and the thermodynamic functions of HoMnO3 ...

Thermal stability of diazodinitrophenol

Thermochimica Acta, 1995
Abstract The stability of diazodinitrophenol in the solid phase has been investigated by four different thermoanalytical methods and by 1 H NMR spectroscopy. The results show that the substance is stable for long periods at temperatures below 60°C.

Thermal stability of Bi2O3

Russian Journal of Inorganic Chemistry, 2007
Differential thermal analysis (DTA) and thermogravimetric analysis (TGA) of an α-Bi2O3 sample revealed staged phase transitions in the range 720–800°C (at 720, 780, and 800°C) and the elimination of oxygen to the composition Bi2O2.967 during heating to 895°C in air at 16 K/min.

Passive thermal stabilization

SPIE Proceedings, 2014
Methods for thermal modeling, analysis and optimization are presented. Modeling distinguishes between three basic types of lens mounts. For analysis also FEA-results are incorporated in the optical model. Optimization with a simple, glass substitution method and a paraxial method is presented.
