Advanced Materials, EarlyView.A novel lignin‐inspired adhesive is presented, that combines the bonding strength of a structural adhesive with on‐demand electrochemical debonding, enabled by biomimetic thiol‐catechol connectivities. Voltage application of only 9 V facilitates electrochemical oxidation of catechols to quinones leading to guided detachment on command.

Miniaturized Devices for On‐the‐Spot Generation of Small‐Diameter Vascular Grafts
Advanced Materials Technologies, EarlyView.An intracorporeal extrusion device is developed for on‐the‐spot generation of vascular grafts with tunable diameters spanning from 1 to 6 mm. The device uses biomimetic polymers and light, to promptly obtaining biocompatible and high‐burst pressure‐resistant grafts.

On the over-production of turbulence beneath surface waves in Reynolds-averaged Navier–Stokes models
Journal of Fluid Mechanics, 2018 In previous computational fluid dynamics studies of breaking waves, there has been a marked tendency to severely over-estimate turbulence levels, both pre- and post-breaking.

The Astrophysical Journal, 2001 We examine the dynamics of turbulent reconnection in 2D and 3D reduced MHD by calculating the effective dissipation due to coupling between small-scale fluctuations and large-scale magnetic fields. Sweet-Parker type balance relations are then used to calculate the global reconnection rate. Two approaches are employed -- quasi-linear closure and an eddy-

Collision‐Resilient Winged Drones Enabled by Tensegrity Structures
Advanced Robotics Research, EarlyView.Based on structures of birds such as the woodpeck, this article presents the collision‐resilient aerial robot, SWIFT. SWIFT leverages tensegrity structures in the fuselage and wings which allow it to undergo large deformations in a crash, without sustaining damage. Experiments show that SWIFT can reduce impact forces by 70% over conventional structures.

Advanced Sensor Research, EarlyView.This study presents a single‐axis airflow sensor featuring a vertically standing laser‐induced graphene (LIG) cantilever on a polyimide substrate. Fabricated entirely using a fiber laser, the sensor integrates surface‐mounted circuits and demonstrates a quadratic response to airflow between −10 and 10 m s−1, offering a simple and scalable approach to ...
