An international team of researchers, affiliated with South Korea's Ulsan National Institute of Science and Technology (UNIST) has unveiled that brittle diamonds can be bent and stretched elastically when made into ultrafine needles.
Researchers from the Universitat Autònoma de Barcelona and Technische Universität Dresden demonstrate the possibility of using ultrastable film formation to improve the performance of state-of-the-art OLEDs. In their joint paper published in Science Advances the researchers show in a detailed study significant increases of efficiency and operational stability (> 15 percent for both parameters and all cases, significantly higher for individual samples) are achieved for four different phosphorescent emitters.
EPFL scientists have found a fast and simple way to make super-elastic, multi-material, high-performance fibers. Their fibers have already been used as sensors on robotic fingers and in clothing. This breakthrough method opens the door to new kinds of smart textiles and medical implants.
Thermoelectric materials, heated under high magnetic fields, could produce record levels of energy, suggests a new study by MIT researchers.
Purdue researchers have discovered a new two-dimensional material, derived from the rare element tellurium, to make transistors that carry a current better throughout a computer chip.
Victor Lakhno, head of the Laboratory of Quantum-Mechanical Systems of the Institute of Mathematical Problems of Biology, RAS has calculated a critical temperature of the transition, energy, heat capacity and heat of transition of an ideal three-dimensional Bose-condensate of translation-invariant bipolarons (TI-bipolarons). The results obtained offer an explanation of the experiments with high-temperature superconductors.
Molecular switch will facilitate the development of pioneering electro-optical devices.
A material with atomically thin layers of water holds promise for energy storage technologies, and researchers have now discovered that the water is performing a different role than anyone anticipated. The finding was possible due to a new atomic force microscopy method that measures the sub-nanoscale deformation rate in the material in response to changes in the material caused by energy storage.
Scientists in Japan have shown that an oxyfluoride is capable of visible light-driven photocatalysis. The finding opens new doors for designing materials for artificial photosynthesis and solar energy research.
Researchers using powerful supercomputers have found a way to generate microwaves with inexpensive silicon, a breakthrough that could dramatically cut costs and improve devices such as sensors in self-driving vehicles.
