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.

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

Polymer Composites, EarlyView.Enhanced impact strength in PLLA‐based composites via ε‐caprolactone incorporation in the matrix. ABSTRACT Inherent brittleness and limited toughness of polylactide (PLA) restrict its use in high‐performance applications. To overcome these limitations, poly(L‐lactide) (PLLA) is often blended with more ductile thermoplastics or chemically modified ...
