Tough, Ductile, and Strong Hard‐Soft Cementitious Composite Enabled by Multi‐Material Additive Manufacturing

Advanced Materials, Volume 38, Issue 45, 13 August 2026.
Drawing inspiration from the layered hard‐soft architecture found in sea sponges, this work establishes a new framework for architected cementitious composites (ACC) through multi‐material additive manufacturing (MMAM) process. The integration of mortar and elastomer phases into layered architectures enables synergistic toughening mechanisms, including

Influence of Carbon Nanoparticles on Electrically Induced Wear of Grease‐Lubricated Steels

Advanced Materials Interfaces, Volume 13, Issue 15, 4 August 2026.
When an electric current enters a pair of rubbing surfaces, enormous damage takes place. In this research, how such damage occurs in the presence of protective grease and the mitigation with added carbon nanoparticles, were investigated. It was discovered that those particles regulate transport and interfacial electrical stability of the grease ...

Comparative study on corrosion resistance and lubrication function of lithium complex grease and polyurea grease

Friction, 2019
In this study, lithium complex grease (LCG) and polyurea grease (PUG) were synthesized using mineral oil (500SN) and polyalphaolefin (PAO40) as base oil, adsorbed onto lithium complex soap and polyurea as thickeners, respectively.

Numerical Visualization of Grease Flow in a Gearbox

Chinese Journal of Mechanical Engineering, 2023
Lubricating greases are widely used in e.g. open gear drives and gearboxes with difficult sealing conditions. The efficiency and heat balance of grease-lubricated gearboxes depend strongly on the lubrication mechanisms channeling and circulating, for ...

Influence of Carbon Nanoparticles on Electrically Induced Wear of Grease‐Lubricated Steels (Adv. Mater. Interfaces 15/2026)

Advanced Materials Interfaces, Volume 13, Issue 15, 4 August 2026.
Tribo‐Electrochemistry This art represents the contact interface of a bearing ball on a grease lubricated metal surface that was abraded with groves. The surface charge was induced by an electric field leading to surface damage. More details can be found in the Research Article by Hong Liang and co‐workers (DOI: 10.1002/admi.70520).

UV‐Enhanced Scanning Electron Microscope: Toward Orientation and Electron Work Function Imaging

Advanced Photonics Research, Volume 7, Issue 8, August 2026.
A complementary deep‐UV illumination system for scanning electron microscope (SEM) is developed at a robust instrument level with precise mechanical control of the focused beam's position and tilt. New SEM imaging modalities are discussed, and future prospects of introducing polarised UV irradiation are outlined by numerical simulations of electron ...
