Phosphorus a promising semiconductor
(Phys.org) —Defects damage the ideal properties of many two-dimensional materials, like carbon-based graphene. Phosphorus just shrugs.
Molecular engineers record an electron's quantum behavior
A team of researchers led by the University of Chicago has developed a technique to record the quantum mechanical behavior of an individual electron contained within a nanoscale defect in diamond. Their technique ...
Topological light: Living on the edge
(Phys.org) —Topology—the understanding of how things are connected—remains abstract, even with the popular example of doughnuts and coffee cups. This concept, esoteric as it appears, is also neat because ...
Rare earth ions in a crystal become candidate for a quantum memory
(Phys.org) —A promising material is lining itself up as a candidate for a quantum memory. A team at the Max Planck Institute for the Science of Light in Erlangen is the first to succeed in performing high-resolution ...
Graphene-boron mix shows promise for lithium-ion batteries
Frustration led to revelation when Rice University scientists determined how graphene might be made useful for high-capacity batteries.
Flawed diamonds: Gems for new technology
(Phys.org) —Using ultra-fast laser pulses, a team of researchers led by UA assistant professor Vanessa Huxter has made the first detailed observation of how energy travels through diamonds containing nitrogen-vacancy ...
Observing the random diffusion of missing atoms in graphene
Imperfections in the regular atomic arrangements in crystals determine many of the properties of a material, and their diffusion is behind many microstructural changes in solids. However, imaging non-repeating ...
Study finds modern relatives of Otzi alive and well in Austria
Chemicals released during natural gas extraction may harm reproduction and development
Unconventional oil and gas (UOG) operations combine directional drilling and hydraulic fracturing, or "fracking," to release natural gas from underground rock. Recent discussions have centered on potential air and water pollution ...
Supersonic spray delivers high quality graphene layer
A simple, inexpensive spray method that deposits a graphene film can heal manufacturing defects and produce a high quality graphene layer on a range of substrates, report researchers at the University of ...
Coral, human cells linked in death
Humans and corals are about as different from one another as living creatures get, but a new finding reveals that in one important way, they are more similar than anyone ever realized.
Taking advantage of graphene defects
A potential application in security screening: new theoretical model for estimation of electric current rectification in graphene
