Inspired by natural foams, researchers have developed graphene-containing composite foams by fermenting with yeast. The process gives the multifunctional composites unusual electrical and mechanical properties

Graphene Composite Foams using Beer Yeasts has many electrical and mechanical applications

by

The use of graphene as an additive can give mechanical and electrical benefits to composite materials, making them multifunctional. In a novel fermentation method, Graphene Flagship researchers have developed graphene-containing rubber foams with unusual mechanical and electrical behaviors: when stretched, the composite foams expand and become more conductive. These unexpected properties could be promising for …

Graphene inherits superconductor qualities when close to superconductors

by

MIT physicists have found that a flake of graphene, when brought in close proximity with two superconducting materials, can inherit some of those materials’ superconducting qualities. As graphene is sandwiched between superconductors, its electronic state changes dramatically, even at its center. The researchers found that graphene’s electrons, formerly behaving as individual, scattering particles, instead pair …

Large scale 1000 mile quantum networks less difficult with new quantum repeater design

by

Arxiv – Semihierarchical quantum repeaters based on moderate lifetime quantum memories The construction of large-scale quantum networks relies on the development of practical quantum repeaters. Many approaches have been proposed with the goal of outperforming the direct transmission of photons, but most of them are inefficient or difficult to implement with current technology. Here, we …

Hair thin fibers were used for two way optical, electrical and chemical signaling within the brain

by

For the first time ever, a single flexible fiber no bigger than a human hair has successfully delivered a combination of optical, electrical, and chemical signals back and forth into the brain, putting into practice an idea first proposed two years ago. With some tweaking to further improve its biocompatibility, the new approach could provide …
