Topology Analysis of Bicycle Rim Brake Pad to Improve Braking Performance

open access: yesMATEC Web of Conferences, 2018
Various parameters of rubber brake pad tribology will affect the braking performance of a rim brake system of a bicycle. Out of those, three main parameters are contact length of brake pad, surface topology of friction surface, and the thickness of rim ...

Topological change of the Fermi surface in ternary iron-pnictides with reduced c/a ratio: A dHvA study of CaFe2P2 [PDF]

open access: yes, 2009
We report a de Haas-van Alphen effect study of the Fermi surface of CaFe2P2 using low temperature torque magnetometry up to 45 T. This system is a close structural analogue of the collapsed tetragonal non-magnetic phase of CaFe2As2.

Correlation-corrected band topology and topological surface states in iron-based superconductors [PDF]

open access: yes, 2022
Iron-based superconductors offer an ideal platform for studying topological superconductivity and Majorana fermions. In this paper, we carry out a comprehensive study of the band topology and topological surface states of a number of iron-based superconductors using a combination of density functional theory (DFT) and dynamical mean field theory.

Microstructural, Surface Topology and Nanomechanical Characterization of Electrodeposited Ni-P/SiC Nanocomposite Coatings

open access: yesApplied Sciences, 2019
In the present study, nickel phosphorous alloys (Ni-P) and Ni-P/ silicon carbide (SiC) nanocomposite coatings were deposited by electrodeposition on steel substrates in order for their microstructural properties to be assessed while using SEM, XRD, and ...

Pressure tuning the Fermi surface topology of the Weyl semimetal NbP [PDF]

open access: yes, 2016
We report on the pressure evolution of the Fermi surface topology of the Weyl semimetal NbP, probed by Shubnikov-de Haas oscillations in the magnetoresistance combined with ab-initio calculations of the band-structure.

Concurrent optimization method of shape and topology for natural vibration problem of shell structures

open access: yesNihon Kikai Gakkai ronbunshu, 2023
In this paper, a concurrent optimization method of shape and topology for natural vibration design of shell structures is presented. The fundamental vibration eigenvalue is maximized under volume constraints for shape and topology optimization.

Tailoring the electronic texture of a topological insulator via its surface orientation [PDF]

open access: yesNew Journal of Physics 15, 103011 (2013), 2013
Three dimensional topological insulator crystals consist of an insulating bulk enclosed by metallic surfaces, and detailed theoretical predictions about the surface state band topology and spin texture are available. While several topological insulator materials are currently known, the existence and topology of these metallic states have only ever ...
