Inject water into silicone oil-
Engraving tube made of one liquid in another liquid.
Scientists foresee a new method of chemically regulating the tube and causing the molecule to flow through the tube, resulting in the separation of molecules or the precise delivery of nano-scale construction blocks to the following
Building compounds.
The researchers printed water lines between 10 microns and 1mm in diameter, as well as various spiral and branch shapes up to a few meters in length.
According to the research published in the journal Advanced Materials, this material can fit the surrounding environment and change the shape repeatedly.
\"This is a class of new materials that can be self-reconfigured and it has the potential to be customized into liquid reaction containers for multiple uses, from chemical synthesis to ion transport to catalysis, tom Russell, a scientist at the Berkeley Lab, said.
There are two advances in the origin of this material: learning how to create a liquid tube in another liquid and then automating the process.
In the first step, scientists have developed a method to cover water pipes with special nanoparticles --
A derived surface active substance that locks water in the appropriate position.
The surface active substance, which is basically soap, prevents the tube from breaking down into droplets.
Their surface active substances are very good, and scientists call them Super soaps of nanoparticles.
This is achieved by dispersing gold nanoparticles into water and dispersing polymer ligand into oil.
The gold nanoparticles and polymer Ligand want to bind to each other, but they also want to remain in their respective water and oil media.
In fact, shortly after the water is injected into the oil, dozens of ligand in the oil are attached to a single nanoparticles in the water to form a super soap of nanoparticles.
These super soaps are blocked together like glass, which can stabilize the interface between oil and water and lock the liquid structure in place.
\"This stability means that we can stretch the water into a pipe, which is still a pipe.
Or we can shape the water into an oval, it\'s still an oval.
\"We have been printing the water pipes for several months with these nanoparticles Super Soap,\" he said . \".
Then the researchers revised one. the-
Shelf 3D printer by removing the components designed to print the plastic and replacing them with syringe pumps and needles that squeeze out the liquid.
They then programmed the printer, inserted the needle into the oil substrate, and injected water in a predetermined pattern.
\"We can squeeze the liquid out of the needle and place anywhere we want in 3D space,\" said postdoctoral researcher Joe Forth . \".
\"We can also ping the material with external forces, which temporarily destroys the stability of the super soap and changes the shape of the water line.
\"These structures are infinitely refactored,\" he said . \"
