Bio-Inspired Soft Grippers Based on Impactive Gripping. [PDF]

Adv Sci (Weinh), 2021
According to movement ways and the classification model inspired by biological “grippers”, the soft grippers are divided into three types: non‐continuum bending‐type grippers, continuum bending‐type grippers, and continuum twisting‐type grippers. For each type of gripper, material properties, device architectures, and manipulation strategies are ...

Research and Application of Vibration Isolation Platform Based on Nonlinear Vibration Isolation System

Journal of Sensors, Volume 2023, Issue 1, 2023., 2023
In order to weaken the ground vibration caused by mechanical equipment, a vibration isolation platform of nonlinear vibration isolation system is proposed. The influence of flexible foundation and nonlinear isolator parameters on the performance of nonlinear vibration isolation platform is studied.

Phase transition in electrorheological plasmas

Contributions to Plasma Physics, Volume 61, Issue 10, November 2021., 2021
Abstract Applying an external electric AC field to a dusty plasma, the micro‐particles arrange in strings or chains. In analogy to electrorheological fluids, such a system is called electrorheological plasma. Turning gradually the AC field into a DC field, the string formation is diminished until it vanishes completely in the DC case.

Physical aspects of dust–plasma interactions

Contributions to Plasma Physics, Volume 61, Issue 10, November 2021., 2021
Abstract Low‐pressure gas discharge plasmas are known to be strongly affected by the presence of small dust particles. This issue plays a role in the investigations of dust particle‐forming plasmas, where the dust‐induced instabilities may affect the properties of synthesized dust particles. Also, gas discharges with large amounts of microparticles are

Electrorheological Fluid Dynamics [PDF]

Physical Review Letters, 2008
We use the Onsager principle to derive a two-phase continuum formulation for the hydrodynamics of the electrorheological (ER) fluid, consisting of dielectric microspheres dispersed in an insulating liquid. Predictions of the theory are in excellent agreement with the experiments.

Structure of electrorheological fluids [PDF]

The Journal of Chemical Physics, 2000
Specially synthesized silica colloidal spheres with fluorescent cores were used as model electrorheological fluids to experimentally explore structure formation and evolution under conditions of no shear. Using confocal scanning laser microscopy we measured the location of each colloid in three dimensions.

On More General Fractional Differential Equations Involving Mixed Generalized Derivatives with Nonlocal Multipoint and Generalized Fractional Integral Boundary Conditions

Journal of Function Spaces, Volume 2020, Issue 1, 2020., 2020
This paper deals with the existence of solutions for a new boundary value problem involving mixed generalized fractional derivatives of Riemann‐Liouville and Caputo supplemented with nonlocal multipoint boundary conditions. The existence results for inclusion case are also discussed.

Synthesis of TiO2/Pd and TiO2/PdO Hollow Spheres and Their Visible Light Photocatalytic Activity

International Journal of Photoenergy, Volume 2020, Issue 1, 2020., 2020
A series of TiO2, TiO2/Pd, and TiO2/PdO hollow sphere photocatalysts was successfully prepared via a combination of hydrothermal, sol‐immobilization, and calcination methods. The structure and optical properties of the as‐prepared samples were characterized by X‐ray diffraction, field emission scanning electron microscopy, transmission electron ...

Advance in investigation on mechanism of electric field treatment for improving the cold flowability of crude oil and its prospect

You-qi chuyun, 2022
High-voltage electric field treatment is an emerging approach to improve the cold flowability of crude oil, of which the physical principle is the negative electrorheological effect of crude oil other than electric heating and electric field dehydration.

Electrorheological Properties of Suspensions of Polypyrrole- Coated Titanate Nanorods

Applied Rheology, 2011
The behaviour of silicone-oil suspensions of titanate nanorods coated with polypyrrole base in electric field has been investigated. Unlike suspension of globular particles of neat polypyrrole, rod-like particles show a stronger electrorheological (ER ...
