Engineering Metal‐Pocket Cooperativity in Single‐Atom COF Nanozymes for Selective Cascade Catalysis

Advanced Materials, EarlyView.
A multilevel programming strategy is developed to engineer single‐atom COF nanozymes with tunable metal centers and chiral pockets inspired by heme–pocket cooperativity. This approach enables controlled metal–pocket interplay for asymmetric cascade catalysis, delivering high activity, selectivity, and recyclability in an asymmetric oxidation–aldol ...

MULTILEVEL MODEL OF EPIDEMIOLOGICAL SAFETY OF ENDOSCOPIC PROCEDURES

Hepatology and Gastroenterology
Background. Traditional control of endoscopic procedures based on recording individual nonconformities does not reflect the mechanisms of epidemiological risk formation and limits the prioritization of management decisions. Objective. To substantiate both a multilevel model of epidemiological safety of endoscopic procedures and its application in a ...

Planning of alternative countermeasures for a station blackout at a boiling water reactor using multilevel flow modeling

Nuclear Engineering and Technology, 2018
Operators face challenges to plan alternative countermeasures when no procedure exists to address the current plant state. A model-based approach is desired to aid operators in acquiring plant resources and deriving response plans.

Dual‐State Programmable Oxide Transistor for Time‐Based Cryptography

Advanced Materials, EarlyView.
A DUPOT enables independently tunable Vth and Isat depending on gate bias polarity, producing three‐dimensional dynamical behavior within a transfer characteristic. This behavior originates from charge trapping and oxygen‐ion migration in the HfO2 layer.
