In Situ Synthesized Glycerol‐Releasing Nanocarriers Unlock Superlubricity in Oil‐Based Lubricants
Macromolecular Materials and Engineering, EarlyView.This study presents an in situ synthesis of glycerol‐based nanocarriers in hydrophobic lubricant oils via inverse miniemulsion polymerization. Encapsulating glycerol within a glycerol‐based polyurethane shell resolves miscibility issues between glycerol and the hydrophobic base oil, yielding novel nanoadditives with tunable glycerol loading.

Viscosity measurement in thin lubricant films using shear ultrasonic reflection [PDF]
, 2008 When a shear ultrasonic wave is incident on a solid and liquid boundary, the proportion that is reflected depends on the liquid viscosity. This is the basis for some instruments for on-line measurement of bulk liquid viscosity.

Exploring the Tribological Properties of 3D Printed Polymer Composites: An Experimental Study
Polymer Composites, EarlyView.Tribological pin‐on‐disc testing of FDM‐manufactured pins. Pins made from PLA, TPU, bronze‐filled PLA (BRO), and their combinations were tested against a SAE 1020 steel disc to evaluate friction, wear, and surface morphology. ABSTRACT In recent years, additive manufacturing, especially 3D printing, has been gaining more space in the production of parts
