Mechanics of fretting fatigue tests
International Journal of Mechanical Sciences, 1987 A popular fretting fatigue test, in which oscillating tension is applied in phase with the fretting force, is analyzed. The configuration is a generalization of the well-known Mindlin contact problem, and it is shown that the addition of bulk tension has a substantial effect on the stick- slip geometry and the shear traction at the interface.

‘Where are the adults?’: Troubling child‐activism and children's political participation
British Educational Research Journal, EarlyView.Abstract Children's political participation is a well‐established theme in childhood studies. In this article we offer an original account of child activism that takes into account the entangled and emergent aspect of children as activists. We begin with a historical and a conceptual review, noting the importance of mid‐20th century developments such ...

Fluorescent Diarylethenes With Polar Groups: Synthesis, Spectra, and Optical Microscopy Applications
Chemistry – A European Journal, EarlyView.Blinking green and flashing red: photo‐switchable and photo‐activatable probes emitting green and red light were prepared and applied as bioconjugates in super‐resolution optical microscopy. ABSTRACT The use of photoactivatable fluorescent diarylethenes (fDAEs) in biology‐related light microscopy has been restricted by the lack of probes having freely ...

THE DANG VAN FATIGUE CRITERION OF THE FRETTING PHENOMENON [PDF]
Analele Universităţii "Constantin Brâncuşi" din Târgu Jiu: Seria Inginerie, 2019 Fretting is now fully identified as a small amplitude oscillatory motion which induces a harmonic tangential force between two surfaces in contact. It is related to three main loadings, i.e. fretting-wear, fretting-fatigue and fretting corrosion.

Fretting fatigue of a shrink-fit pin subjected to rotating bending : Experiments and simulations [PDF]
, 2009 Fretting fatigue initiation was studied for a shrink-fit pin at rotating bending. Eight assemblies with four different grips were manufactured from soft normalized steel and tested at loads well below bending endurance.

Nonthermal plasma approaches for combating implant‐associated infections: A compendious review
VIEW, EarlyView.Implant‐associated infections pose serious clinical challenges. Non‐thermal plasma (NTP) modifications overcome this bottleneck in distinct ways relative to traditional sterilization methods. Gas‐phase plasmas generate highly energetic species, UV radiation and reactive oxygen/nitrogen species (RONS), which alter the implant surface properties.
