Order out of disorder: working cycle of an intrinsically unfolded chaperone. [PDF]

open access: yesCell, 2012
SUMMARY The redox-regulated chaperone Hsp33 protects organisms against oxidative stress that leads to protein unfolding. Activation of Hsp33 is triggered by the oxidative unfolding of its own redox-sensor domain, making Hsp33 a member of a recently ...

ORC and sCO2 cycle for high temperature WHR applications [PDF]

open access: yesMATEC Web of Conferences, 2022
This article suggests a suitable closed thermodynamic cycle for waste heat from a cement plant by using alternative working fluids. A pair of closed working cycles is compared: supercritical CO2 cycle (sCO2) and the Organic Rankine Cycle (ORC).
