Effect of Zr-doped CaCu3Ti3.95Zr0.05O12 ceramic on the microstructure, dielectric properties, and electric field distribution of the LDPE composites

open access: yese-Polymers, 2023
Small-size CaCu3Ti3.95Zr0.05O12 enhanced dielectric constant of LDPE by 88.5% due to enhancing interfacial polarization included by ultrahigh interfacial area (∼3.0 × 105 m2) and played a prominent role in homogenize electric field distribution in LDPE ...

Algorithm for determining specific interfacial surface area of bubbles from image (on the example of ultrasound aeration) [PDF]

open access: yesE3S Web of Conferences, 2023
The process of increasing the interfacial surface by means of ultrasonic oscillations in cavitation mode under forced aeration is considered. An algorithm for image processing of the interfacial surface to determine its specific area is proposed.

Fused filament fabrication: comparison of methods for determining the interfacial strength of single welded tracks

open access: yesManufacturing Review, 2021
The mechanical properties of plastic-based additively manufactured specimens have been widely discussed. However, there is still no standard that can be used to determine properties such as the interfacial strength of adjacent tracks and also to exclude ...

Interfacial waves in the presence of areas of slip [PDF]

open access: yesGeophysical Journal International, 1994
SUMMARY Interfacial waves are considered propagating along, or incident upon, an interface between two orthotropic elastic materials which presents special mechanical matching conditions, involving elastic slip along the whole of the interface or in localized areas (one isolated interfacial crack or a periodic array of such cracks).

Simulation of Delamination Evolution of Slab Ballastless Track under Vertical Impact

open access: yesShock and Vibration, 2021
During the running of a high-speed train, the wheel may bounce on the rail due to the track irregularity. The wheel bounce could generate a vertical impact, leading to the initiation and expansion of delamination between layers of the track structure. In

A New Method for Evaluating the Bond Strength of Plasma-Sprayed NiCrBSi Coatings

open access: yesMetals, 2022
The bond strength is a critical consideration for the plasma-sprayed NiCrBSi coatings. However, the conventional methods for testing the bond strength of NiCrBSi coatings always cost time and money. If there is a simple method that could predict the bond

Interfacial area measurement methods [PDF]

open access: yes, 1989
This report describes the ongoing development of experimental techniques for measurement of local specific interfacial area in gas-liquid and liquid-liquid two-phase systems. Mathematical relations between local specific interfacial area and measurable quantities are derived based on kinematics and geometry.
