Characterization and Selection of Contractile Actuators for Soft Robotics Operating in the Quasistatic Regime

open access: yesAdvanced Intelligent Systems, EarlyView.
We developed methods to characterize soft contractile actuators using force–displacement measurements in the passive state and the total force in the active state and define the operational range of thermal, electrothermal, and pneumatic muscles. A graphical method enables the selection of an actuator based on the required mechanical force–displacement

Isosteric Engineering of Enzymes: Overcoming Activity–Stability Trade‐Offs by Site‐Selective CH → N Substitutions

open access: yesAngewandte Chemie, EarlyView.
Coupling biosynthetic noncanonical amino acid production with genetic code expansion enables site‐specific incorporation of azatryptophans into PET‐degrading enzymes (PETases). By isosteric single‐atom editing of a conserved tryptophan, AzaPETases break the activity–stability trade‐off, delivering higher catalytic efficiency at elevated temperature and
