Study on the Effect of Laser Quenching on Fretting Fatigue Life
Metals, 2019 Laser quenching hardening is one of the most used surface treated technologies. In order to study the effect of laser quenching on the fretting fatigue life, fretting fatigue experiments of TC11 (Ti-6.5Al-1.5Zr-3.5Mo-0.3Si) titanium alloy specimens with ...

A crack-like notch analogue for a safe-life fretting fatigue design methodology [PDF]
, 2003 Various analogies have recently been proposed for comparing the stress fields induced in fretting fatigue contact situations, with those of a crack and a sharp or a rounded notch, resulting in a degree of uncertainty over which model is most appropriate ...

Chinese Journal of Mechanical Engineering, 2021 At present, there are many studies on the residual stress field and plastic strain field introduced by surface strengthening, which can well hinder the initiation of early fatigue cracks and delay the propagation of fatigue cracks. However, there are few

Advanced Science, EarlyView.A series of photo‐responsive polymers are prepared by a facile one‐pot in situ synthesis strategy, where RTP modules and photochromic units are systematically integrated into one polymer system. The triplet‐singlet Förster resonance energy transfer (TS‐FRET) between the donor and acceptor enables the material to exhibit time‐dependent phosphorescence ...

‘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 ...

Design of a fretting fatigue test rig with compliant springs [PDF]
, 2013 Fretting is a small amplitude oscillatory movement which occurs between contacting bodies who are subjected to cyclic loading or vibrations. In the contact area arise stresses -normal and tangential- causing stress concentrations and surface degradation.

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 ...
