Engineering Electron Transfer Flux between Cytochrome P450 Enzyme and P450 Reductase to Enhance Serotonin Production in Escherichia Coli

open access: yesAdvanced Science, EarlyView.
The electron transfer flux in CPR‐P450 catalytic system is systematically engineered through: i) enhancing electron transfer rate by redesigning the putative electron transfer pathway of CPR; ii) improving electron‐receiving rate by evolving the heme domain of tryptophan‐5‐hydroxylase (T5H); iii) enlarging electron supply by fine‐tuning NADPH synthesis.

An experimental investigation of three dimensional low speed minimum interference wind tunnel for high lift wings [PDF]

open access: yes
As a means to achieve a minimum interference correction wind tunnel, a partially actively controlled test section was experimentally examined. A jet flapped wing with 0.91 m (36 in) span and R = 4.05 was used as a model to create moderately high lift ...

Tumor Microenvironment Triggered In Situ Coagulation of Supramolecularly Engineered Platelets for Precise Tumor Embolization

open access: yesAdvanced Science, EarlyView.
Occlusion of tumor blood vessels represents a promising yet challenging approach in cancer treatment. Herein, supramolecularly engineered platelets conjugated with morphology‐transformable nanoparticles is developed for precise tumor embolization. The engineered platelets actively accumulate at tumor sites following induced blood vessel injury.

Residual Stresses and Micro‐voids Propel Metal Diffusion for Filament‐Based Memristors

open access: yesAdvanced Science, EarlyView.
Introducing non‐reactive nitrogen during silver sputtering enables low‐voltage (<60 mV) switching in memristors via nano‐void formation and residual stresses in the gigapascal range. This promotes sub‐micron filamentation and neuromorphic behaviors, including multi‐peak synaptic responses.

Transonic wind-tunnel wall interference [PDF]

open access: yes
A method for analyzing wall interference is described which avoids the assumption of linear superposition of perturbations in extracting the wall induced velocity field.
