Organic semiconductors play a crucial role in the functionality of many electronic devices we use on a daily basis. These semiconductors, which are based on organic molecules containing carbon, interact with light to create excitons in the material. Excitons are formed when electrons become excited after absorbing light energy and combine with leftover “holes.” This

Combinatorial optimization problems have long been a challenge for conventional computing methods due to their complexity and the exponential growth of computation time as the size of the problem increases. The traveling salesman problem, in particular, is a classic example that illustrates this issue. In this problem, a salesman needs to find the shortest route
Projection mapping has long been a popular technique for creating visually stunning displays on real-world objects. However, one common limitation has always hindered its potential – the need for darkness. Without a dark environment, the projected images do not come out as intended, with black and dark colors appearing too bright and glowing. The recent
Tantalum is known to be one of the rarest elements, with multiple stable isotopes. Among these isotopes, Ta-180 stands out as the least abundant and possesses a long-lived excited state, which is an exceptional feature unique to this particular isotope. In excited states, the protons or neutrons within a nuclei exhibit higher energy levels than
In the pursuit of perfecting quantum systems, scientists have typically focused on minimizing noise that could disrupt the function of quantum computers. However, researchers at the Niels Bohr Institute (NBI) have taken a different approach by harnessing noise to process quantum information. This unconventional method has resulted in a significant improvement in the performance of
Recent research has unveiled a groundbreaking new design for high-efficiency blue organic light-emitting diodes (OLEDs), promising longer-lasting and higher definition television screens. The study, published in Nature Materials, presents a simplified structure that could potentially address the existing drawbacks of OLED displays, such as high costs and short lifespans. The potential implications of this new
In a groundbreaking collaboration between 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, a novel strategy has been developed to improve the efficiency and stability of blue light-emitting diodes (LEDs) based on perovskite materials. This research, recently
In a groundbreaking discovery, researchers at Kobe University have unveiled the key to efficiently combining two low-energy photons into one high-energy photon. This finding holds immense potential for the development of more efficient photovoltaic (PV) cells, OLED displays, and even anti-cancer therapies. The process of up-conversion involves absorbing light and transferring its energy among molecules
In a recent study conducted by researchers at the Department of Energy’s Oak Ridge National Laboratory, significant advancements in quantum-based cybersecurity have been demonstrated in a real-world fiber optic network. This study builds upon previous research conducted in 2015 and showcases the potential for quantum key distribution as a secure method for sharing confidential information.
Fusion power plants are seen as the future of clean, sustainable energy. However, in order for these plants to be commercially viable, they must be able to create and sustain the plasma conditions necessary for fusion reactions. One of the challenges faced in achieving this is the development of instabilities such as edge localized modes
