Computational design of the temperature optimum of an enzyme reaction [PDF]
Science Advances, 2023 Cold-adapted enzymes are characterized both by a higher catalytic activity at low temperatures and by having their temperature optimum down-shifted, compared to mesophilic orthologs. In several cases, the optimum does not coincide with the onset of protein melting but reflects some other type of inactivation.

Optimum light weight concrete mix design against high temperature [PDF]
مهندسی عمران شریف, 2022 The fire phenomenon can cause the loss of structural materials resistance which may end to damage or even structural total collapse. Physical and chemical changes in concrete due to firing also make serious structural defects in concrete structures ...

Comparison of Structural Features of CRISPR-Cas Systems in Thermophilic Bacteria
Microorganisms, 2023 The clustered regularly interspaced short palindromic repeat (CRISPR) is an adaptive immune system that defends most archaea and many bacteria from foreign DNA, such as phages, viruses, and plasmids. The link between the CRISPR-Cas system and the optimum
