Creep curve measurement to support wear and adhesion modelling, using a continuously variable creep twin disc machine [PDF]
, 2013 Predictive modelling of wear and adhesion at rolling-sliding contacts such as a railway rail and wheel depends on understanding the relationship between slip and shear force at the contact surface, i.e. the creep verses force curve.

In‐Wheel Piezoelectric DC Power Generator With Zero Resistive Torque
Advanced Science, EarlyView.In this paper, we present a wheel‐shaped direct‐current piezoelectric generator (DC‐PG) that fundamentally overcomes these constraints by producing phase‐stable DC electricity directly from rolling motion. By embedding this system into suitcase wheels, we demonstrated a fully integrated real‐time location tracking system powered solely by mechanical ...

Rolling-element fatigue life of AISI M-50 and 18-4-1 balls [PDF]
Rolling element fatigue studies were conducted with AISI M-50, EFR 18-4-1, and VAR 18-4-1. Groups of 12.7 mm (1/2-in) diameter balls of each material were tested in the five ball fatigue tester.

Interaction of laser generated ultrasonic waves with wedge-shaped samples [PDF]
, 2012 Wedge-shaped samples can be used as a model of acoustic interactions with samples ranging from ocean wedges, to angled defects such as rolling contact fatigue, to thickness measurements of samples with non-parallel faces.

Advanced Science, EarlyView.A solvent‐free, open‐mill shear protocol nucleates 2.6 nm CsPbBr3 QDs uniformly within brominated butyl rubber. The emitters showed 91% PLQY, 1189 ns lifetime, and > 90% retention after 30‐day ambient storage and water immersion, respectively. Board‐to‐board forms 17 × 17 cm2 flexible films for 132% NTSC white LEDs, scintillators, and stretchable ...

The effects of lapping load in finishing advanced ceramic balls on a novel eccentric lapping machine [PDF]
, 2005 HIPed (Hot Isostatically Pressed) silicon nitride ball blanks were lapped from diameter 13.255 mm to diameter 12.7 mm by a novel eccentric lapping machine. A maximum material removal rate of 68 μm/hour has been achieved under a nominal lapping load of 43
