Analysis of Salt Mixture Contamination on Insulators via Laser-Induced Breakdown Spectroscopy

open access: yesApplied Sciences, 2020
The composition of contamination deposited on transmission line insulators can affect their surface flashover voltage. Currently, there is no rapid on-line method to detect this contamination composition in power grids.

Are Topological Insulators Promising Thermoelectrics?

open access: yes, 2023
Some of the best thermoelectric (TE) materials to date are also topological insulators (TIs). While many studies have investigated the effects of topologically-protected surface states on TE properties, the conditions needed to realize such effects are ...

3D Printed Polymer Photonic Topological Insulators and their Robustness to Fabrication Disorder

open access: yes, 2022
Photonic topological insulators have emerged as an exciting new platform for backscatter-free waveguiding even in the presence of defects, with applications in robust long-range energy and quantum information transfer, spectroscopy and sensing, chiral ...

Superconductor–insulator transitions and insulators with localized pairs [PDF]

open access: yesPhysics-Uspekhi, 1998
Two experiments are described which are related to the problem of localized Cooper pairs. Magnetic-field-tuned superconductor-insulator transition was studied in amorphous In--O films with onset of the superconducting transition in zero field near 2 K. Experiments performed in the temperature range T>0.3 K indicate that at the critical field, B=B_c,

Highly Conducting Single-Molecule Topological Insulators Based on Mono- and Di-Radical Cations

open access: yes, 2022
Single-molecule topological insulators are promising candidates as conducting wires over nanometer length scales. In past, most conjugated molecular wires exhibit low conductance that decays as the wire length increases.

Analysis and design of carbon fibre clamping apparatus for replacement of insulator strings in ultra-high voltage transmission line

open access: yesThe Journal of Engineering, 2019
Aiming at the characteristics of closed fixtures such as large size, heavy weight and difficulty in high-altitude operation, this study proposed a design method to improve the clamping apparatus for replacement of insulator strings in the ultra-high ...

Nuclear conversion theory: molecular hydrogen in non-magnetic insulators [PDF]

open access: yesRoyal Society Open Science, 2016
The hydrogen conversion patterns on non-magnetic solids sensitively depend upon the degree of singlet/triplet mixing in the intermediates of the catalytic reaction. Three main ‘symmetry-breaking’ interactions are brought together.

Interferometric schemes: a probe for topological edge states, a tool in weak measurements [PDF]

open access: yes, 2014
In the first part of this thesis we propose interferometric schemes to probe the properties of edge states of topological insulators and superconductors.

A Review on Real-Size Epoxy Cast Resin Insulators for Compact High Voltage Direct Current Gas Insulated Switchgears (GIS) and Gas Insulated Transmission Lines (GIL)—Current Achievements and Envisaged Research and Development

open access: yesEnergies, 2020
Due to the ever-increasing demand for electricity in the one hand and the environmental constraints to use clean energy on the other hand, the global production of energy from remote renewable sources, particularly from large hydropower plants and ...
