Scientists at the Advanced Science Research Center (ASRC) at the Graduate Center, CUNY, worked to theorize and test how two layers of graphene — each one-atom thick — could be made to transform into a diamond-like material upon impact at room temperature. The team also found the moment of conversion resulted in a sudden reduction …
Samsung has created a graphene ball coating for use inside a regular li-ion battery cells, which will increase the overall capacity by up to 45 percent and speeding up charging by five times. Nature Communications – Graphene balls for lithium rechargeable batteries with fast charging and high volumetric energy densities Improving one property without sacrificing …
Scientists at Rutgers University-New Brunswick have learned how to tame the unruly electrons in graphene, paving the way for the ultra-fast transport of electrons with low loss of energy in novel systems. Above – A sharp tip creates a force field that can trap electrons in graphene or modify their trajectories, similar to the effect …
Researchers from Finland and Taiwan have discovered how graphene, a single-atom-thin layer of carbon, can be forged into three-dimensional objects by using laser light. A striking illustration was provided when the researchers fabricated a pyramid with a height of 60 nm, which is about 200 times larger than the thickness of a graphene sheet. The …
An international team of researchers, including scientists from Shinshu University (Japan) and the director of Penn State’s ATOMIC Center, has developed a graphene-based coating for desalination membranes that is more robust and scalable than current nanofiltration membrane technologies. The result could be a sturdy and practical membrane for clean water solutions as well as protein …
Arkansas Business reports Alliance Rubber of Hot Springs recently signed an agreement with University of Sussex professor Alan Dalton to study how the compound graphene could be used in rubber products. Alliance Rubber intends to help determine exactly how this super-material could be used in its products, so the company has teamed up with researchers …
In some high-quality materials, like graphene, electrons can travel micron distances without scattering, improving the conductivity by orders of magnitude. This so-called ballistic regime, imposes the maximum possible conductance for any normal metal, which is defined by the Landauer-Buttiker formalism. Three different experiments, including one performed by The University of Manchester, demonstrated that at certain …
A research team, led by Professor Nicola Pugno at the University of Trento, Italy, succeeded in having their spiders produce silk with up to three times the strength and ten times the toughness of the regular material. This could pave the way for a new class of bionicomposites, with a wide variety of uses. Professor …
Researchers have achieved a leap forward in graphene production, from a technique that synthesizes a few square centimeters of single-crystal graphene in a couple of hours, to an optimized method that allows the creation of an almost-perfect (over 99.9 percent aligned) 5 × 50 cm2 single-crystal graphene in just 20 minutes. The low production costs, …
Researchers develop a novel technique using graphene to create solar cells they can mount on surfaces ranging from glass to plastic to paper and tape. Imagine a future in which solar cells are all around us — on windows and walls, cell phones, laptops, and more. A new flexible, transparent solar cell developed at MIT …
MIT engineers have fabricated a functional dialysis membrane from a sheet of graphene — a single layer of carbon atoms, linked end to end in hexagonal configuration like that of chicken wire. The graphene membrane, about the size of a fingernail, is less than 1 nanometer thick. (The thinnest existing memranes are about 20 nanometers …
