2D Skeletal Muscle Thin Film Actuators Enhance Efficiency of Biohybrid Robots
2D skeletal muscle thin film actuators generate millinewton‐scale forces and millimeter‐scale strokes while remaining functional for over 30 days. Their force density is 20‐fold higher than 3D skeletal muscle actuators, enabling multi‐fin robots with tunable speed and multidirectional steering.

Effect of Prandtl's ration on balance in geophysical turbulence [PDF]
Support for this research has come from the UK Engineering and Physical Sciences Research Council (grant no. EP/H001794/1).The fluid dynamics of the atmosphere and oceans are to a large extent controlled by the slow evolution of a scalar field called ...

Global behaviour corresponding to the absolute instability of the rotating-disc boundary layer [PDF]
A study is carried out of the linear global behaviour corresponding to the absolute instability of the rotating-disc boundary layer. It is based on direct numerical simulations of the complete linearized Navier–Stokes equations obtained with the novel ...

Influence of design parameters on the global performances of low-speed counter-rotating axial-flow fans [PDF]
The present work aims at experimentally investigating the effects of some parameters on the performances of a counter-rotating stage, and on the instationary flow between the rotors.

Architecture‐Driven Functional Coupling in Vertically Aligned Nanocomposites
Vertically aligned nanocomposites define a growth‐engineered architecture in which vertical interfaces, strain fields, defect pathways, and phase connectivity are created simultaneously. This review shows how these architectural features couple ferroic, optical, ionic, electrochemical, and device responses, establishing design rules and open challenges

Nonlinear dynamics of a rotating shaft with a breathing crack [PDF]
In this paper, the effects of a breathing crack on the vibratory characteris- tics of a rotating shaft are investigated. A new, simple and robust model composed of two rigid bars connected with a nonlinear flexural spring is proposed.
