A longstanding problem in physics has finally been cracked by Professor Kostya Trachenko of Queen Mary University of London's School of Physical and Chemical Sciences. His research, published in Physical Review E, unveils a general theory for predicting melting points, a fundamental property whose...
Images projected onto objects in the real world create impressive displays that educate and entertain. However, current projection mapping systems all have one common limitation: they only work well in the dark. In a study recently published in IEEE Transactions on Visualization and Computer...
Tantalum is one of the rarest elements and has multiple stable isotopes. The least abundant tantalum isotope, Ta-180 is found naturally in a long-lived excited state, a feature unique to this isotope. In excited states, a nuclei's protons or neutrons have higher than normal energy levels....
There are many ways to store data—digitally, on a hard disk, or using analog storage technology, for example as a hologram. In most cases, it is technically quite complicated to create a hologram: High-precision laser technology is normally used for this....
Long-wavelength infrared (LWIR) imaging holds critical significance across many applications, from consumer electronics to defense and national security. It finds applications in night vision, remote sensing, and long-range imaging. However, the conventional refractive lenses employed in these...
Prof. Cui Linsong's research team from the University of Science and Technology of China (USTC), cooperating with Prof. Samuel D. Stranks' team from the University of Cambridge, devised a novel strategy to enhance the performance of blue light-emitting diodes (LEDs) based on perovskite materials....
Researchers have found a new way to simplify the structure of high-efficiency blue organic light-emitting diodes (OLEDs), which could lead to longer-lasting and higher definition television screens....
Electrical engineers have determined the theoretical fundamental limit for how much electromagnetic energy a transparent material with a given thickness can absorb. The finding will help engineers optimize devices designed to block certain frequencies of radiation while allowing others to pass...
Chip-based devices known as frequency combs, which measure the frequency of light waves with unparalleled precision, have revolutionized timekeeping, the detection of planets outside of our solar system and high-speed optical communication....
A team of engineers has proven that their analog computing device, called a memristor, can complete complex, scientific computing tasks while bypassing the limitations of digital computing....
