The ROF+ methodology for grease life testing [PDF]
, 2013 Very often, the service life of grease lubricated rolling bearings is determined by the so called “grease life”. This can be tested on R0F test rigs, which have been available for this since more than 40 years.

Advanced Optical Materials, EarlyView.A proline‐integrated donor–acceptor fluorophore enables multifunctional luminescence through rational molecular design. Water‐vapor‐responsive mechanochromic luminescence (MCL) with circularly polarized luminescence (CPL) switching and efficient visualization of latent fingerprints (LFPs) are realized from this single small organic molecule.

Advanced Robotics Research, EarlyView.This article presents dielectric elastomer switch (DES) materials, based on composite thin films. Alignment of graphite flakes due to their physical confinement within the thin films lead to much stronger piezoresistive responses than bulk composites, while their durability exceeds that of conventional liquid‐based DES materials.

Inflation and labor market flexibility: The squeaky wheel gets the grease [PDF]
Inflation can "grease" the wheels of the labor market by relaxing downward wage rigidity but it can also increase uncertainty and have a negative "sand" effect.

Degradable Magnetic Composites from Recycled NdFeB Magnets for Soft Actuation and Sensing
Advanced Robotics Research, EarlyView.This work presents a degradable soft magnetic composite made from recycled NdFeB particles embedded in a gelatin‐based organogel. The material is processed into magnetic sensors and soft robotic components, which can later be dissolved in a green solvent to recover NdFeB magnetic particles.

Effect of Base Oil Type in Grease Composition on the Lubricating Film Formation in EHD Contacts
Lubricants, 2018 The service life of rolling bearings is significantly affected by the film formation in elastohydrodynamic (EHD) contacts, which depends on the operating conditions, like rotational speed or temperature.

Inflation and unemployment revisited: grease vs. sand [PDF]
, 1998 As inflation rates in the United States decline, analysts are asking if there are economic reasons to hold the rates at levels above zero. Previous studies of whether inflation "greases the wheels" of the labor market ignore inflation's potential for ...
