Anisotropic semi-Dirac electrons in atomically-precise trilayers

In Arthur C. Clarke’s classic SF novel Against the Fall of Night, there is a description of the “moving ways”, the powered sidewalks on which people rode around the city, as being made of a material that would have baffled an engineer of our own times because it was solid in one direction and liquid… Continue reading Anisotropic semi-Dirac electrons in atomically-precise trilayers

Graphitic memory

A recent paper from Feynman Prize winner James Tour’s group at Rice relates an interesting new form of memory based on a bistable 2-terminal graphitic switch. Once developed, the switch could form the basis of a high-density non-volatile storage which might replace flash devices (which are already beginning to replace magnetic disks). Rice press release

Mass production method for nanotechnology wonder material

The publication of a method to mass produce graphene has opened the way to further study of this remarkable nanomaterial.

Another nanotechnology route to better ultracapacitors for energy storage

Chemically modified graphene has found in manganese oxide nanoflower/carbon nanotube array a rival nanotech material to improve energy storage using ultracapacitors.

Impermeable membrane one atom-thick for nanotechnology

Nanotech has fashioned from graphene a one atom-thick membrane impermeable even to helium gas.

Diamond mechanosynthesis for atomically precise nanotechnology to be explored experimentally

A pioneering UK program aimed at developing a nanofactory has made a £1.53M ($3M) award to Professor Philip Moriarty of the University of Nottingham to support a five-year series of experiments to investigate the possibility of diamond mechanosynthesis, testing the theoretical proposals recently made by Robert Freitas and Ralph Merkle. Details are contained in the… Continue reading Diamond mechanosynthesis for atomically precise nanotechnology to be explored experimentally

One-atom thick carbon gauze via nanotechnology

The ever-vigilant Physorg.com brings us news of a one-atom thick freestanding (i.e., unattached) graphene carbon film: Physicists pioneer new super-thin technology Physicists at The University of Manchester and The Max-Planck Institute in Germany have created a new kind of a membrane that is only one atom thick. It’s believed this super-small structure can be used… Continue reading One-atom thick carbon gauze via nanotechnology

World's First Single-Atom-Thick Fabric

molecool writes "PhysOrg writes that researchers at The University of Manchester and Chernogolovka, Russia have discovered the world's first single-atom-thick fabric, which reveals the existence of a new class of materials and may lead to computers made from a single molecule. The research is to be published in Science on 22 October."

Ed. Note. The molecular fabric is single layer graphite (graphene) and which is hardly a "discovery". It is of course useful that it can be manipulated in the laboratory and possibly at an industrial level. For those with access to Science, the URL for the publication is here
