Crystal structure of β-glucosidase from Thermotoga neapolitana (PDB: 5IDI).Thermostable protein, active at 80°C and with unfolding temperature of 101°C. [1]In materials science and molecular biology, thermostability is the ability of a substance to resist irreversible change in its chemical or physical structure, often by resisting decomposition or polymerization, at a high relative ...
They are also characterized by high strength and stiffness, retaining these properties between −100 °C and 150 °C. The glass transition temperature of polysulfones is between 190 and 230 °C. [9] They have a high dimensional stability, the size change when exposed to boiling water or 150 °C air or steam generally falls below 0.1%. [10]
Resulting operating temperatures might be between 200 °C in the case of PES to 260 °C in case of PEI or PAI. [7] The increase in temperature stability by incorporating aromatic units is due to the fact, that the temperature stability of a polymer is determined by its resistance against thermal degradation and its oxidation resistance.
The protein molecules in the hyperthermophiles exhibit hyperthermostability—that is, they can maintain structural stability (and therefore function) at high temperatures. Such proteins are homologous to their functional analogs in organisms that thrive at lower temperatures but have evolved to exhibit optimal function at much greater ...
Ultra-high-temperature ceramics (UHTCs) are a type of refractory ceramics that can withstand extremely high temperatures without degrading, often above 2,000 °C. [1] They also often have high thermal conductivities and are highly resistant to thermal shock, meaning they can withstand sudden and extreme changes in temperature without cracking or breaking.
A superalloy, or high-performance alloy, is an alloy with the ability to operate at a high fraction of its melting point. [1] Key characteristics of a superalloy include mechanical strength , thermal creep deformation resistance, surface stability, and corrosion and oxidation resistance.
In thermodynamics, thermal stability describes the stability of a water body and its resistance to mixing. [1] It is the amount of work needed to transform the water to a uniform water density . The Schmidt stability "S" is commonly measured in joules per square meter (J/m 2 ).
The high decomposition temperature and high stability at over 400 °C suggests a polymer with benzimidazole as the repeating unit may also show high heat stability. Polybenzimidazole and its aromatic derivatives can withstand temperatures in excess of about 500 °C (932 °F) without softening and degrading.
