A technique to create sub-10-nm graphene nanoribbons from squashed carbon nanotubes
Graphene nanoribbons (GNRs) are narrow and long strips of graphene with widths below 100 nm. GNRs that have smooth edges, a sizable bandgap and high charge carrier mobility could be highly valuable for a wide range of electronic and optoelectronic ap.....»»
Physicists demystify magic: bona fide topological Mott insulator discovered in twisted bilayer graphene model
Imagine stacking two sheets of graphene—the 2D form of graphite, or the pencil at your hand—in which the carbon atoms form a hexagonal lattice and twist the top sheet out of alignment with the sheet below, yielding a periodic arrangement of atoms.....»»
Grabbing magic tin by the tail
Atomic nuclei have only two ingredients, protons and neutrons, but the relative number of these ingredients makes a radical difference in their properties. Certain configurations of protons and neutrons, with "magic numbers" of protons or neutrons ar.....»»
Ground-breaking bacteria-killing viruses unite with antibiotics to fight devastating antibiotic-resistant bacteria
Mycobacterium abscessus, a relative of the bacteria that cause tuberculosis and leprosy, is responsible for particularly severe damage to human lungs and can be resistant to many standard antibiotics, making infections extremely challenging to treat......»»
Vertica in Leader’s Circle of GigaOm Radar Report for Data Warehouses
For the second consecutive year, GigaOm has positioned Vertica in the “leader’s circle” of its Radar Report for Data Warehouses. In the report – “a forward-looking analysis that plots the relative value and progression of vendor solutions a.....»»

Lexar recently released two new high speed PCIe 4.0 SSDs, promising to bring extreme performance at a competitive price. The Professional NM800 SSD lineup targets content creators and gamers, and is intended for installation on both desktops and lapt.....»»
Hidden Particle Interactions Exposed by Peeling Layers of Graphene
Ions flowing through atom-thin stacks of carbon confirm classic theories but also yield new surprises -- Read more on ScientificAmerican.com.....»»
Phase changing in graphite by interface charge injection
Graphite, as an important material for Li battery anode and graphene preparation, can exist in two phases: the Bernal (2H) phase and the rhombohedral (3R) phase. The 2H phase has relatively low energy and high proportion in graphite powder, while the.....»»
One-dimensional red phosphorous glows in unexpected ways
When electrons are confined into very small spaces, they can exhibit unusual electrical, optical and magnetic behavior. From confining electrons in two-dimensional atomic sheet graphene—a feat that won the Nobel Prize in physics in 2010—to restri.....»»
Youngest class members face low educational achievement, increased incidence of substance abuse: study
New research from the Institute of Psychiatry, Psychology & Neuroscience (IoPPN) at King's College London, in collaboration with the Karolinska Institute and Orebro University, has found that 'young relative age'—being young in a school class—put.....»»
Invisible barrier breakthrough a boon for electronics, artwork and more
Curtin University researchers have found applying a thin invisible layer of graphene oxide to silicon forms an impermeable barrier, which could be used to protect artwork, prevent corrosion of metals, and produce higher efficiency solar cells......»»
Graphene binds drugs that kill bacteria on medical implants
Bacterial infections relating to medical implants place a huge burden on healthcare and cause great suffering to patients worldwide. Now, researchers at Chalmers University of Technology, Sweden, have developed a new method to prevent such infections.....»»
Enterprise AI 2.0: The acceleration of B2B AI innovation has begun
Two decades after businesses started deploying AI solutions, one can argue they’ve made little progress in achieving significant gains in efficiency relative to the hype that drove expectations. Eshwar Belani Contribut.....»»
Using graphene foam to filter toxins from drinking water
Some kinds of water pollution, such as algal blooms and plastics that foul rivers, lakes, and marine environments, lie in plain sight. But other contaminants are not so readily apparent, which makes their impact potentially more dangerous. Among thes.....»»
Effective EMI shielding behavior of thin graphene/PMMA nanolaminates
Since its isolation in 2004 by Geim and Novoselov from the University of Manchester (Nobel Prize in Physics in 2010), graphene has been termed a 'wonder material' due to its exceptional properties, which have already been exploited in many applicatio.....»»
Mimicking brain functions with graphene-diamond junctions
