Existence of Weak Solutions for the Equations of a Non‐Newtonian Fluid With Non‐Standard Growth
ABSTRACT We consider the equations of a non‐Newtonian incompressible fluid in a general time‐space cylinder ΩT=Ω×(0,T)⊂Rn×R,n≥2$\Omega _{T} = \Omega \times (0,T) \subset \mathbb {R}^{n} \times \mathbb {R}, n \ge 2$. We assume that the rheology of the fluid is changing with respect to time and space, and satisfies, for each (x,t)∈ΩT$(x,t) \in \Omega _{T}

Bio‐Inspired Molecular Events in Poly(Ionic Liquids)
Originating from dipolar and polar inter‐ and intra‐chain interactions of the building blocks, the topologies and morphologies of poly(ionic liquids) (PIL) govern their nano‐ and micro‐processibility. Modulating the interactions of cation‐anion pairs with aliphatic dipolar components enables the tunability of properties, facilitated by “bottom‐up ...

The Electric Field Responses of Inorganic Ionogels and Poly(ionic liquid)s
Ionic liquids (ILs) are a class of pure ions with melting points lower than 100 °C. They are getting more and more attention because of their high thermal stability, high ionic conductivity and dielectric properties.

Scalable High‐Force Zipping Electrostatic Actuators
An electrostatic actuator architecture is presented that combines high energy density with forces and strokes suited for wearable soft robotics. By folding patterned thin films into a scalable honeycomb of zipping units, performance becomes tunable through series–parallel design, achieving over 40 N and 28 J/kg.

External Vibrations on Early‐Age Concrete: A Review
Scientific illustration of external vibration, their influencing properties and effects, possible outcomes and measures adapted. ABSTRACT Early‐age concrete exhibits limited mechanical strength, making it highly susceptible to external disturbances such as vibrations from construction activities, traffic, or nearby machinery which can disrupt internal ...

Characterization and Testing of an Electrorheological Fluid Valve for Control of ERF Actuators
Previous studies of electrorheological fluids (ERFs) were motivated by brake, clutch, damping, haptic and resistive applications, but never motivated towards developing an ERF based-hydraulic rotary actuator. One design to make such an actuator is to use
