Phase transition may explain how brain neurons encode information
Study Yields Surprising New Insight into High-Temp Superconductors
Impurity size affects performance of emerging superconductive material
Research from North Carolina State University finds that impurities can hurt performance – or possibly provide benefits – in a key superconductive material that is expected to find use in a host of applications, ...
Researchers develop nanodiamond thermometer to take temperature of individual cells
Superconducting qualities of topological insulators demonstrated
(Phys.org) —Topological insulators (TIs) are an exciting new type of material that on their surface carry electric current, but within their bulk, act as insulators. Since the discovery of TIs about a decade ...
Disorderly conduct: Probing the role of disorder in quantum coherence
A new experiment conducted at the Joint Quantum Institute (JQI) examines the relationship between quantum coherence, an important aspect of certain materials kept at low temperature, and the imperfections ...
'Unzipped' carbon nanotubes could help energize fuel cells, batteries
Multi-walled carbon nanotubes riddled with defects and impurities on the outside could replace some of the expensive platinum catalysts used in fuel cells and metal-air batteries, according to scientists at ...
Innovative nanoparticle purification system uses magnetic fields
A team of Penn State University scientists has invented a new system that uses magnetism to purify hybrid nanoparticles -- structures that are composed of two or more kinds of materials in an extremely small ...
Disorder is key to nanotube mystery
Scientists often find strange and unexpected things when they look at materials at the nanoscale -- the level of single atoms and molecules. This holds true even for the most common materials, such as water.
Advanced instrument used to read cells' minds
Researchers at the Stanford University School of Medicine have taken a machine already in use for the measurement of impurities in semiconductors and used it to analyze immune cells in far more detail than ...
Mpemba effect: Why hot water can freeze faster than cold
Nanophysicists find unexpected magnetic effect: Kondo effect noted in single-atom contacts of pure ferromagnets
Spanish and U.S. physicists studying nanoelectronics have found that size really does matter when it comes to predicting the behavior of electrical contacts that are just one atom wide.
Researchers develop "game-changing" gas separation membrane
(Phys.org) —Refining, whether oil or natural gases, can be a costly process because of the need to remove impurities found when extracting them from the ground. Currently expensive materials are used to ...
Spectrum imaging used to measure atom concentrations at atomic resolution
The ability to locate and count small numbers of impurity atoms could lead to advances in modern electronics and optical fiber communication networks.
