Lubrication in cold rolling: Elasto-plasto-hydrodynamic lubrication [PDF]

, 1993
A model has been developed with respect to hydrodynamic lubrication in cold rolling. The basic model describes the configuration of a rigid, perfectly plastic sheet rolled by a rigid work roll.

In Situ 3D Bioprinting: Impact of Cross‐Linking on the Adhesive Properties of Hydrogels

Advanced Functional Materials, EarlyView.
In situ 3D bioprinting enables the direct deposition of cell‐laden, adhesive biomaterials for on‐site tissue regeneration. This review provides a comprehensive overview of how cross‐linking influences the bioadhesive properties of hydrogels used in 3D bioprinting, highlighting cross‐linking triggers, bioadhesion mechanisms, polymer interpenetration ...

Polymer Infiltration Into SURMOF Channels Enables Hydrophobic and Solid‐Like Slippery Functional Thin Films

Advanced Functional Materials, EarlyView.
We report a polymer‐chain insertion strategy to fabricate pore‐threaded MOF thin films with precisely tuned surface chemistry and wettability. Grafting n‐alkane chains into the pillared layer Cu2(bdc)2(dabco) MOF thin film's vertical nanochannels enhances water stability, and induces hydrophobicity and lubricant‐free, solid‐like slippery behavior ...

Parallel 3D Bioprinting on SLIPS‐Microarrays

Advanced Functional Materials, EarlyView.
This work introduces the first truly parallel 3D bioprinting method, enabling both the simultaneous fabrication of hundreds of cell laden hydrogel 3D structures and their HTS in individual liquid compartments. By integrating Digital Light Processing (DLP) stereolithography with functional micropatterns, the platform decouples printing time from array ...

Free surface flows with large slopes: beyond lubrication theory

, 2006
The description of free surface flows can often be simplified to thin film (or lubrication) equations, when the slopes of the liquid-gas interface are small.

Multi‐Responsive Dendrimer‐Hyaluronic Acid Hydrogel With Lubricating and Immunoregulatory Functions for Synergistic Osteoarthritis Therapy

Advanced Functional Materials, EarlyView.
A hydrogel with dynamic cross‐links was formed by cross‐linking hyaluronic acid with curcumin‐preloaded, phenylboronic acid‐modified poly(amidoamine) dendrimers. This hydrogel exhibited excellent injectability and self‐healing ability, enabling controlled Cur release in response to low pH, high reactive oxygen species (ROS) generation, or mechanical ...

Curvature‐Tuned Friction at Electrified Ionic Liquid Interfaces

Advanced Functional Materials, EarlyView.
Graphene curvature plays a key role in friction electrotunability at single‐asperity contacts lubricated by ionic liquids. A 9 nm radius yields stronger tunability than larger radii, with distinct friction coefficients at low and high loads indicating a shift in the slippage plane.
