A discussion on the measurement of grinding media wear

Journal of Materials Research and Technology, 2016
Comminution operations are the most expensive and energy consuming in the mineral industry. Any action aiming at reducing the costs associated with that step is welcome, and lowering the consumption of grinding media figures among the main concerns ...

Composites of Shellac and Silver Nanowires as Flexible, Biobased, and Corrosion‐Resistant Transparent Conductive Electrodes

Advanced Functional Materials, EarlyView.
Shellac, a centuries‐old natural resin, is reimagined as a green material for flexible electronics. When combined with silver nanowires, shellac films deliver transparency, conductivity, and stability against humidity. These results position shellac as a sustainable alternative to synthetic polymers for transparent conductors in next‐generation ...

Covalent Functionalization of 2D Semiconductors: A Roadmap to Advanced Electronic Devices

Advanced Functional Materials, EarlyView.
This Review presents recent advances in the covalent functionalization strategies for two‐dimensional semiconductors and their implementation in modern technologies. Layered materials are modified through diverse molecular chemistries (e.g., thiols, diazonium salts, alkyl halides, and electron‐deficient species) to tailor their surface properties ...

Effect of steel hardness on soot wear [PDF]

, 2017
Due to incomplete combustion, high levels of soot can accumulate in engine lubricants between drain intervals. This soot can promote wear of engine parts such as timing chains and cam followers.

Out‐of‐Plane Strain‐Decoupled Architecture for High‐Fill‐Factor Stretchable OLED Displays

Advanced Functional Materials, EarlyView.
A vertically decoupled multilayer SOLED architecture separates emissive pixel islands from deformable interconnects, allowing low‐modulus elastomeric layers to accommodate applied strain and suppress strain transfer to the OLED region. This design, combined with transparent hybrid encapsulation, enables a high fill factor (∼75%), stretchability ...
