Features of the Mechanisms of Conductivity of the Electrorheological Fluids With Double Doped TiO2 Particles Under External Temperature Effects

open access: yesFrontiers in Materials, 2019
Electrophysical and rheological characteristics of ER fluids with TiO2 particles doped with aluminum and phosphorus and having anatase structure are considered in an extended temperature range (5–100°C). The mechanisms of leakage currents in the ER fluid

Realizing self-powered mechanical transmission control system via triboelectric nanogenerator and electrorheological fluid composed soft starter

open access: yesNano Research Energy, 2023
Soft starters are effective devices used to provide overload protection for motors from large mechanical shocks during the start-up period. However, existing soft starters require additional power supplies, sensors, and complex control elements that pose

Continuum modelling of electrorheological fluids

open access: yesElectrorheological Fluids and Magnetorheological Suspensions, 2002
A thermodynamical continuum modelling is proposed for electrorheological fluids. This theormodynamical approach tries to describe the response of an electrorheological fluid in the solid phase (which means with an applied adequate electric field) under mechanical solicitations. Thermodynamic formulations distinguish the contributions due to reversible

New Modular Fixed-Point Theorem in the Variable Exponent Spaces ℓp(.)

open access: yesMathematics, 2022
In this work, we prove a fixed-point theorem in the variable exponent spaces ℓp(.), when p−=1 without further conditions. This result is new and adds more information regarding the modular structure of these spaces.

Microfluidic Valve‐Integrated Garment for Smooth Sequential Gradient Mechanotherapy

open access: yesAdvanced Intelligent Systems, Volume 8, Issue 8, August 2026.
We present a soft wearable sleeve that delivers smooth, gap‐free compression using overlapping air‐filled actuators and tiny microfluidic valves. The system reduces bulk, lowers power needs, and uses a smartphone‐sized control box. It can provide sequential gradient compression, gradient pressure holding, and fast deflation, supporting more portable ...

Self‐improving property for certain degenerate functionals with generalized Orlicz growth

open access: yesBulletin of the London Mathematical Society, Volume 58, Issue 8, August 2026.
Abstract We investigate a self‐improving property of variational integrals in a weighted framework under generalized Orlicz growth conditions. Assuming that the weight belongs to an appropriate Muckenhoupt class and the growth function satisfies standard structural conditions, we prove that the gradient of any local quasi‐minimizer has local higher ...

Electric alignment of plate shaped clay aggregates in oils

open access: yesFrontiers in Physics, 2016
We experimentally investigate the rotation of plate shaped aggregates of clay mineral particles immersed in silicone oil. The rotation is induced by an external electric field.

Weak Solutions for a Class of Nonlocal Singular Problems Over the Nehari Manifold

open access: yesMathematical Methods in the Applied Sciences, Volume 49, Issue 11, Page 12360-12378, 30 July 2026.
ABSTRACT In this paper, we consider a nonlocal model of dilatant non‐Newtonian fluid with a Dirichlet boundary condition. By using the Nehari manifold and fibering map methods, we obtain the existence of at least two weak solutions, with sign information.

Current Trends in Fluid Viscous Dampers with Semi-Active and Adaptive Behavior

open access: yesApplied Sciences, 2023
Fluid viscous dampers (FVDs) have shown their efficiency as energy-dissipating systems, reducing the effects induced on structures by dynamic loading conditions like earthquakes and winds. In this paper, the evolution of this technology is reviewed, with
