Topology Analysis of Bicycle Rim Brake Pad to Improve Braking Performance

MATEC 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 ...

Surface states of topological insulators

Physical Review B, 2012
We develop an effective bulk model with a topological boundary condition to study the surface states of topological insulators. We find that the Dirac point energy, the band curvature and the spin texture of surface states are crystal face-dependent. For a given face on a sphere, the Dirac point energy is determined by the bulk physics that breaks p-h ...

Circles in the Sky: Finding Topology with the Microwave Background Radiation [PDF]

, 1996
If the universe is finite and smaller than the distance to the surface of last scatter, then the signature of the topology of the universe is writ large on the microwave background sky.

Study of Microstructure, Texture, and Cooking Qualities of Reformulated Whole Wheat Flour Pasta by Substituting Water with Stearic Acid–Candelilla Wax–Groundnut Oil Oleogel

ChemEngineering
Oleogels, which are traditionally utilized to reduce saturated and trans fats in bakery foods, have recently shown promising applications in non-bakery foods, particularly in the enhancement of their food texture and cooking qualities.

Fermi Surface Reconstruction by Dynamic Magnetic Fluctuations [PDF]

, 2012
We demonstrate that nearly critical quantum magnetic fluctuations in strongly correlated electron systems can change the Fermi surface topology and also lead to spin charge separation (SCS) in two dimensions.

Electrical and topological properties of oxides films grown thermally on InSe substrates [PDF]

Tekhnologiya i Konstruirovanie v Elektronnoi Apparature, 2010
The surface resistance dynamics of oxides grown thermally on InSe substrates in two crystallography planes is obtained. It is determined that resistance changes considerably only during the first 5 minutes of the oxidization period.

Three-gradient regular solution model for simple liquids wetting complex surface topologies

Beilstein Journal of Nanotechnology, 2016
We use regular solution theory and implement a three-gradient model for a liquid/vapour system in contact with a complex surface topology to study the shape of a liquid drop in advancing and receding wetting scenarios.
