New 'self-healing' gel makes electronics more flexible - 1 views

  •  
    Maybe something to look at for Ricarda? Researchers in the Cockrell School of Engineering at The University of Texas at Austin have developed a first-of-its-kind self-healing gel that repairs and connects electronic circuits, creating opportunities to advance the development of flexible electronics, biosensors and batteries as energy storage devices. "There's no need for heat or light to fix the crack or break in a circuit or battery, which is often required by previously developed self-healing materials." Yu and his team created the self-healing gel by combining two gels: a self-assembling metal-ligand gel that provides self-healing properties and a polymer hydrogel that is a conductor.

Repeated self-healing in composite materials - 1 views

  •  
    Sottos, White, Moore, and their team created 3D vascular networks-patterns of microchannels filled with healing chemistries-that thread through a fiber-reinforced composite. When damage occurs, the networks within the material break apart and allow the healing chemistries to mix and polymerize, autonomously healing the material, over multiple cycles.

Light bends itself round corners - physicsworld.com - 1 views

  •  
    The Florida team generated a specially shaped laser beam that could self-accelerate, or bend, sideways.
  •  
    very nice!!! read this e.g. "In addition to this self-bending, the beam's intensity pattern also has a couple of other intriguing characteristics. One is that it is non-diffracting, which means that the width of each intensity region does not appreciably increase as the beam travels forwards. This is unlike a normal beam - even a tightly collimated laser beam - which spreads as it propagates. The other unusual property is that of self-healing. This means that if part of the beam is blocked by opaque objects, then any disruptions to the beam's intensity pattern could gradually recover as the beam travels forward."

Nissan announces world's first self-healing iPhone case - 1 views

  •  
    Just over six years ago, we reported that Nissan had developed a "Scratch Guard Coat" paint designed to repair scratches on not only cars, but on painted surfaces in general. ... The Scratch Shield paint is made from polyrotaxane, which has a chemical structure that is able to react and change back to its original shape and fill the gap that results from a fine scratch.

Self-healing plastic that regenerates mimicking blood clots - 1 views

  •  
    A vascular synthetic system that restores mechanical performance in response to large-scale damage. Gap-filling scaffolds are created through a two-stage polymer chemistry that initially forms a shape-conforming dynamic gel but later polymerizes to a solid structural polymer with robust mechanical properties.

    The material the team used in these initial proof-of-concept experiments did make use of one biological component - chloroplasts, the light-harnessing components within plant cells, which the researchers obtained from spinach leaves.

Bioinspired self-repairing slippery surfaces with pressure-stable omniphobicity : Natur... - 3 views

  • a strategy to create self-healing, slippery liquid-infused porous surface(s) (SLIPS) with exceptional liquid- and ice-repellency, pressure stability and enhanced optical transparency. Our approach—inspired by Nepenthes pitcher plants13—is conceptually different from the lotus effect, because we use nano/microstructured substrates to lock in place the infused lubricating fluid. We define the requirements for which the lubricant forms a stable, defect-free and inert ‘slippery’ interface.
  • ts capability to repel various simple and complex liquids (water, hydrocarbons, crude oil and blood),

    ...This slippery surface was bio-inspired by the carnivorous plant I showed you sometimes ago! I was sure it was a good idea! next time I will be quicker!!

    Shit. I am sure that there is more to do on this. Let's have a closer look.
  •  
    And a good lesson that it is important to proceed quickly when you have an idea and don't wait ...
  •  
    Yes, I will see what we could do, but they really did a good job, from the biomimetic of the surface, up to the realization of the material, and the tests...

New Supergel Has Strange Biological Properties - 0 views

  •  
    Linked to the discussion we had last week on elastically non-linear polymers. The inverted liquid->solid phase transition might be interesting and the material might be self-healing just above the transition.
