Shifting dimensions: Exciting excitons in unusual 2D material
Scientists have explored how an excited state of matter -- excitons -- behaves in phosphorene, a two-dimensional material that could be used in LEDs, solar cells, and other optoelectronic devices....
Researchers propose a novel methodology for the characterization of light-matter interaction at atomic size
Photonic cavities are an essential part of many modern optical devices, from laser pointers to microwave ovens. Just as we can store water in a tank and create standing waves on the...
Study shows how diligent we have to be to keep surfaces germ-free
A recent study suggests that even organized efforts to clean surfaces can fall short, a reminder for us all that keeping our surroundings clean may require some additional work.
Look: 5SOS shares stop-motion lyric video for 'Wildflower'
5 Seconds of Summer released "Wildflower," a new single from their upcoming album "Calm."
Innovative thinner electrolyte can improve functioning of solid oxide fuel cells
In this post-industrialization age, electricity has become the backbone of our society. However, using fossil fuels to generate it is not the best option because of their limited availability and...
A nanoscale device to generate high-power terahertz waves
Terahertz (THz) waves fall between microwave and infrared radiation in the electromagnetic spectrum, oscillating at frequencies of between 100 billion and 30 trillion cycles per second. These waves are prized...
Researchers discover giant cavity in key tuberculosis molecule
Researchers from the Department of Energy's SLAC National Accelerator Laboratory have discovered a strange new feature of a protein that's thought to be important in the development of tuberculosis: The...
A new idea for rapid generation of strong magnetic fields using laser pulses
