A review of fretting study on nuclear power equipment
, 2020Nuclear power plants, working in extremely harsh environment, primarily in the form of high-speed fluid flow, circulate through complex systems. Serious tribological problems can occur when a small amount of nuclear energy is converted into mechanical ...

Fretting fatigue and fretting wear
Tribology International, 1989Abstract In this paper fretting wear and fretting fatigue is reviewed on the basis of work carried out by the present authors and by other investigators. The effects of amplitude, time, materials, contact temperature, frequency, stress and environment are discussed.

Experimental study on fretting-fatigue of bridge cable wires
, 2020Bridge cables are subjected to small relative sliding and high contact stresses among wires under fluctuating loads and repeated bending, eventually leading to fretting-fatigue failure.

Fretting wear of bolted joint interfaces
Wear, 2020Under vibration loading, fretting wear between bolted joint interfaces may change the dynamic characteristics of structures. Even the reliability of long-lasting assembly structures could be affected.

An experimental investigation on fretting wear behavior of copper–magnesium alloy
, 2020The fretting wear behavior of copper–magnesium alloy (Cu–Mg alloy) used for high-speed railway catenary system was investigated. Fretting tests of Cu–Mg alloy cylinder against Cu–Mg alloy cylinder at vertical cross contact configuration were carried out ...

Förster (or Fluorescence) Resonance Energy Transfer (FRET) is unique in generating fluorescence signals sensitive to molecular conformation, association, and separation in the 1-10 nm range. We introduce a revised photophysical framework for the phenomenon and provide a systematic catalog of FRET techniques adapted to imaging systems, including new ...
