Protein sterilization method of firefly luciferase using reduced pressure and molecular sieves [PDF]

open access: yes, 1973
The sterilization of the protein fruitfly luciferase under conditions that prevent denaturation is examined. Denaturation is prevented by heating the protein in contact with molecular seives and under a reduced pressure of the order of 0.00005 ...

Study on damage and failure characteristics of loaded gas‐bearing rock–coal–rock combination structures

open access: yesDeep Underground Science and Engineering, EarlyView.
The influence of gas on the instability and failure of rock–coal–rock combinations is considered. The damage characteristics of gas‐bearing rock–coal–rock combinations under different confining pressures, axial loading rates, and gas are revealed. A constitutive model for gas‐bearing rock–coal–rock damage considering gas is established.

Synthesis of Coal Tar‐Based Hypercrosslinked Polymers via Friedel‐Crafts Alkylation: An Efficient Way to Access Carbon Electrode Material for Supercapacitors

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Liquid coal tar (CT) is synthesized into hypercrosslinked polymers (HCPs) via the Friedel–Crafts alkylation, followed by oxidation‐carbonization to form disordered microporous carbon. The resulting CF2CT exhibits a high three‐electrode specific capacitance of 342 F g−1 at 1 A g−1, and the assembled symmetric supercapacitor illuminates a light sign ...
