Jan 07, 2022 (Nanowerk News) Researchers from Paragraf and Queen Mary University of London demonstrated the successful fabrication of an Organic Light-Emitting Diode (OLED) with a monolayer graphene anode, replacing ITO in organic light-emitting diodes (Advanced Optical Materials, "Wafer-Scale Graphene Anodes Replace Indium Tin Oxide in Organic Light-Emitting Diodes"). Indium...
How scientists are ‘looking’ inside asteroids
Jan 07, 2022 (Nanowerk News) Asteroids can pose a threat to life on Earth but are also a valuable source of resources to make fuel or water to aid deep space exploration. Devoid of geological and atmospheric processes, these space rocks provide a window onto the evolution of the solar...
Exploration of new frequency frontiers
Jan 07, 2022 (Nanowerk News) When matter is irradiated by ultrashort laser pulses, excited electrons scatter on femtosecond timescales. A femtosecond is a millionth of a billionth of a second. Information about the scattering and other fast processes in the material can be extracted from the wave characteristics of transmitted...
Biotechnology could provide an environmentally more sustainable alternative to egg white protein production
Jan 07, 2022 (Nanowerk News) Egg white is one of the most important protein ingredients for the food industry. The first assessment of the environmental impact of egg white protein – ovalbumin – production by fungus Trichoderma reesei shows that the ovalbumin produced by precision fermentation reduced land use requirements...
Light-matter interactions at the atomic scale simulated on the world’s fastest supercomputer
Jan 07, 2022 (Nanowerk News) Lightâmatter interactions form the basis of many important technologies, including lasers, light-emitting diodes (LEDs), and atomic clocks. However, usual computational approaches for modeling such interactions have limited usefulness and capability. Now, researchers from Japan have developed a technique that overcomes these limitations. In a study...
Traditional Xuan paper inspires development of new high-haze transparent film
Jan 06, 2022 (Nanowerk News) Xuan paper, known as one of the Four Treasures of the Study, is an important carrier for traditional Chinese calligraphy and painting art, and it is also a precious cultural heritage of the Chinese nation. It has a history of more than 1,500 years and...
Physicists watch as ultracold atoms form a crystal of quantum tornadoes
Jan 06, 2022 (Nanowerk News) The world we experience is governed by classical physics. How we move, where we are, and how fast we’re going are all determined by the classical assumption that we can only exist in one place at any one moment in time. But in the quantum...
Scientists contemplate launching tiny lifeforms into interstellar space
Jan 06, 2022 (Nanowerk News) No longer solely in the realm of science fiction, the possibility of interstellar travel has appeared, tantalizingly, on the horizon. Although we may not see it in our lifetimes — at least not some real version of the fictional warp-speeding, hyperdriving, space-folding sort — we...
First realistic portraits of squishy layer that’s key to battery performance
Jan 06, 2022 (Nanowerk News) Lithium metal batteries could store much more charge in a given space than today’s lithium-ion batteries, and the race is on to develop them for next-gen electric vehicles, electronics and other uses. But one of the hurdles that stand in the way is a silent...
Nematicity is a new piece in a phase diagram puzzle
Jan 06, 2022 (Nanowerk News) Although twisted sheets of double bilayer graphene have been studied extensively the past few years, there are still pieces missing in the puzzle that is its phase diagram—the different undisturbed, ground states of the system. Writing in Nature Physics ("Moiré nematic phase in twisted double...
