In Situ Synthesized Glycerol‐Releasing Nanocarriers Unlock Superlubricity in Oil‐Based Lubricants
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.

Ionic liquids (ILs) have matured from laboratory curiosities to eco‐smart, molecularly tunable media underpinning sustainable chemical technologies. This review integrates a bibliometric mapping of the 2000–2025 literature with a critical synthesis of IL design principles, structure–property relationships, and application landscapes.

Characterization of Tribofilm from Sulfurized Mohwa Oil [PDF]
The reaction products of sulfurized Mohwa oil with iron powder in hydrocarbon medium at 150°C for 8 h were studied to investigate the type of lubricant films formed during their application as antiwear and extreme pressure additives. The main reaction product was isolated on the basis of its solubility in mixed solvent.

A Different Perspective on the Solid Lubrication Performance of Black Phosphorus: Friend or Foe?
Researchers investigate black phosphorus (BP) as a standalone solid lubricant coating through ball‐on‐disc linear‐reciprocating sliding experiments in dry conditions. Testing on different metals shows BP doesn't universally reduce friction and wear. However, it achieves 33% friction reduction on rougher iron surfaces and 23% wear reduction on aluminum.

State‐of‐the‐Art, Insights, and Perspectives for MOFs‐Nanocomposites and MOF‐Derived (Nano)Materials
Different approaches to MOF‐NP composite formation, such as ship‐in‐a‐bottle, bottle‐around‐the‐ship and in situ one‐step synthesis, are used. Owing to synergistic effects, the advantageous features of the components of the composites are beneficially combined, and their individual drawbacks are mitigated.

Characterization and Biolubricant Performance of Marinobacter alanticus Lipid Extract
Graphical Abstract and Lay Summary M. atlanticus was cultivated, lipids were extracted, and materials characterization and tribology testing was performed to evaluate the bacterium as a biolubcricant source. ABSTRACT Renewable and sustainable materials to replace petroleum‐based lubricants are increasingly sought in tribology and energy applications ...
