Emission spectra are a widely used method for identifying chemical compounds; the bright lines reveal the different frequencies of light that can be emitted by an atom. Here, a normal emission spectrum for an atom in a high-energy state...
A tetraquark is a particle with four quarks, which are the fundamental constituents of matter.Credit: Image courtesy of Syracuse University Physicists in the Syracuse University College of Arts and Sciences have made science history by confirming the existence of a...
Hydrogen is the most-abundant element in the universe. It's also the simplest--sporting only a single electron in each atom. But that simplicity is deceptive, because there is still so much we have to learn about hydrogen. One of the biggest...
Freezing water is a central issue for climate, geology and life. On earth, ice and snow cover 10 percent of the land and up to half of the northern hemisphere in winter. Polar ice caps reflect up to 90...
The NIST-4 watt balance has measured Planck's constant to within 34 parts per billion, demonstrating that the high-tech scale is accurate enough to assist with 2018's planned redefinition of the kilogram. Credit: J. L. Lee/NIST A high-tech version of an...
When a free neutron (green) undergoes a process known as beta decay, it produces a proton (red), an antineutrino (gold) and an electron (blue), as well as a photon (white). An experiment at NIST measured the range of energies...
Temperature distribution in an active plasmonic waveguide on an optoelectronic chip with a cooling system Researchers from MIPT have found a solution to the problem of the overheating of active plasmonic components for high-speed data transfer in the optoelectronic...
Yale scientists have found a way to amplify the intensity of light waves on a silicon microchip.Credit: Yale University Yale scientists have found a way to greatly boost the intensity of light waves on a silicon microchip using the power...
Scientists can now identify the exact location of a single atom in a silicon crystal, a discovery that is key for greater accuracy in tomorrow's silicon based quantum computers. It's now possible to track and see individual phosphorus atoms in...
