Imine Crosslinked, Injectable, and Self‐Healing Fucoidan Hydrogel with Immunomodulatory Properties

Advanced Healthcare Materials, EarlyView.
This study develops an injectable fucoidan‐based hydrogel with tunable properties for tissue engineering. By oxidizing fucoidan (OFu) to introduce aldehydes, imine crosslinks are formed with amine‐containing polymers, enabling self‐healing, injectability, and long‐term stability (≥28 days). The OFu‐gelatin hydrogel demonstrated biocompatibility, immune‐

Enhancing Form Stability: Shrink‐Resistant Hydrogels Made of Interpenetrating Networks of Recombinant Spider Silk and Collagen‐I

Advanced Healthcare Materials, EarlyView.
A shrinkage‐resistant hydrogel is developed to confer post‐fabrication shape fidelity. The hydrogel, based on recombinant spider silk protein eADF4(C16)‐RGD and collagen‐I, exhibits tunable mechanical properties and shrink‐resistance in the presence of fibroblasts as well as muscle cells.

Morphogenic Growth 3D Printing

Advanced Materials, EarlyView.
I additive manufacturing process exploits the spatial propagation of a polymerization reaction front to produce 3D polymer parts 10× faster and 1000× more energy efficient than the fastest stereolithography. In contrast with existing 3D printing, this morphogenic process is inspired by biological “growth and form” due to the self‐directed propagation ...

Viscoelastic lubrication of a submerged cylinder sliding down an incline [PDF]

arXiv
Lubrication flows between two solid surfaces can be found in a variety of biological and engineering settings. In many of these systems, the lubricant exhibits viscoelastic properties, which modify the associated lubrication forces. Here, we experimentally study viscoelastic lubrication by considering the motion of a submerged cylinder sliding down an ...

Viscoelasticity of Human Blood

Biophysical Journal, 1972
Measurements made for oscillatory flow of blood in circular tubes show that blood possesses elastic properties which make consideration of its viscous properties alone inadequate. Results are for a frequency of 10 Hz while varying the amplitude of the velocity gradient for red blood cells in plasma at concentrations ranging from 0 to 100% apparent ...

Developing Cathode Films for Practical All‐Solid‐State Lithium‐Sulfur Batteries

Advanced Materials, EarlyView.
The development of all‐solid‐state lithium‐sulfur batteries offers higher specific energies and lower costs compared to state‐of‐the‐art Li‐ion batteries. However, a lack of mechanistic understanding hinders advancement. This review analyzes key electrode parameters, evaluates progress in enhancing ion/electron percolation, and addresses ...

Fatigue‐Resistant Mechanoresponsive Color‐Changing Hydrogels for Vision‐Based Tactile Robots

Advanced Materials, EarlyView.
Mechanoresponsive color‐changing materials that can reversibly and resiliently change color in response to stress are highly desirable for diverse technologies in optics, sensors, and robots; however, such materials are rarely achieved. This work reports a fatigue‐resistant mechanoresponsive color‐changing hydrogel that exhibits reversible, resilient ...
