The pink strip lies flat on a black-and-white checkerboard surface. It s rubbery gummy, almost and just thicker than an unrolled fruit leather snack. At a glance, the strip seems unremarkable.
Introduce heat, however, and the strip transforms. Arching and extending, it wriggles like an inchworm, contorting itself independently. Remove the thermal stimulus, and the strip returns to its original form.
It seems like magic, or at least a trick of the imagination, but it s really just chemistry. What looks like a rubber strip is a piece of phase-changing material made of liquid crystal elastomers, or LCEs. The material, which becomes an artificial muscle ....

Carbon Nanotube Membranes can Enable Rapid Dialysis Processes

Carbon Nanotube Membranes can Enable Rapid Dialysis Processes
Written by AZoNanoJan 8 2021
Scientists from the Lawrence Livermore National Laboratory have found that ultra-rapid dialysis processes could be achieved by carbon nanotube membrane pores, resulting in considerably reduced treatment time for patients undergoing hemodialysis.
Artistic rendering of fast ion permeation inside single-walled carbon nanotubes. Small ions such as potassium, chloride, and sodium permeate through the inner volume of nanometer-wide carbon nanotubes at rates that surpass diffusion in bulk water by an order of magnitude.

In manmade and biological processes, the potential to isolate molecular components in complex solutions is very important. One way to do this is to apply a concentration gradient across a porous membrane. This method fuels molecules or ions that are smaller in comparison to the pore diameters ....
