From solar panels to OLED TV screens, organic semiconductors play a crucial role in many electronic devices. These semiconductors, based on organic molecules like buckminsterfullerene, are essential for the interaction between light and materials. The behavior of organic semiconductors in the presence of light is determined by the formation of excitons, which are pairs of
The traveling salesman problem has long been a challenge for conventional computers due to its complexity as the number of cities increases. However, a recent study led by Prof. Dr. Jens Eisert of Freie Universität Berlin and HZB has shed light on how quantum computers could offer a faster and more efficient solution to this
Quantum computing has long been seen as the future of technology, offering the potential to revolutionize data processing and computational power. However, one of the biggest challenges in quantum systems has been the presence of noise, which can disrupt the functionality of quantum computers. Traditionally, scientists have sought to eliminate noise from quantum systems. However,
The world of projection mapping has seen significant advancements in recent years, allowing for mesmerizing displays that transform ordinary objects into interactive canvases. However, a common limitation that has plagued existing systems is their reliance on darkness to achieve optimal results. The need for darkness stems from the fact that any surrounding illumination not only
Tantalum, one of the rarest elements, is known for having multiple stable isotopes. Among these isotopes, Ta-180 stands out as the least abundant and is found naturally in a long-lived excited state, a characteristic that sets it apart from other elements. Despite being energetically possible, the radioactive decay of the excited state in Ta-180m has
In a recent study published in Nature Materials, researchers have discovered a groundbreaking new way to simplify the structure of high-efficiency blue organic light-emitting diodes (OLEDs). This new design could potentially lead to television screens with longer lifespans and higher definition quality. OLEDs are already used in smartphones and displays due to their efficiency, but
In a groundbreaking study published in Nature Photonics, Prof. Cui Linsong’s research team from the University of Science and Technology of China (USTC) and Prof. Samuel D. Stranks’ team from the University of Cambridge have unveiled a novel strategy to enhance the performance of blue light-emitting diodes (LEDs) based on perovskite materials. Perovskite LEDs have
Photon up-conversion is a process that involves combining two low-energy photons into one high-energy photon. This efficient conversion of energy has numerous applications in various fields such as photovoltaic cells, organic light-emitting diode (OLED) displays, and even anti-cancer therapies. Researchers around the world have been working tirelessly to develop materials that can facilitate this up-conversion
In a groundbreaking study conducted by researchers at the Department of Energy’s Oak Ridge National Laboratory, the potential for advanced quantum-based cybersecurity in a deployed fiber link was demonstrated. The results of this study, published in CLEO 2023, build upon a proof-of-principle experiment performed by ORNL scientists in 2015. One of the key aspects of
