Quantum dot light-emitting diodes (QLEDs) have made rapid progress in luminescence, efficiency, and stability, making them promising candidates for displays and solid-state lighting applications. However, achieving high-performance QLEDs with high color purity remains a persistent challenge, particularly red QLEDs, thus limiting the popularity of ultra-high definition devices. Recently, Soochow University, in collaboration with Macau University of Science and Technology and other research institutes, reported a facile high-temperature successive ion layer adsorption and reaction (HT-SILAR) strategy for the growth of high-quality,…
Scientists at Penn State have harnessed a unique property called incipient ferroelectricity to create a new type of computer memory that could revolutionize how electronic devices work, such as using much less energy and operating in extreme environments like outer space. They published their work, which focuses on multifunctional two-dimensional field-effect transistors (FETs), in Nature Communications. FETs are advanced electronic devices that use ultra-thin layers of materials to control electrical signals, offering multiple functions like switching, sensing or memory in a…
The ancient peoples of the Philippines and of Island Southeast Asia (ISEA) may have built sophisticated boats and mastered seafaring tens of thousands of years ago—millennia before Magellan, Zheng He, and even the Polynesians. In a new paper coming out in the April 2025 issue of the Journal of Archaeological Science: Reports, Ateneo de Manila University researchers Riczar Fuentes and Alfred Pawlik challenge the widely-held contention that technological progress during the Paleolithic only emerged in Europe and Africa. They point…
All humans need clean water to live. However, purifying water can be energy-intensive, so there is great interest in improving this process. Researchers at Tohoku University have reported a strategy using data-driven predictions coupled with precise synthesis to accelerate the development of single-atom catalysts (SACs) for more robust and efficient water purification. SACs are one of the most crucial catalysts. They play a pivotal role in enhancing efficiency in diverse applications including chemical industries, energy conversion, and environmental processes. For…
Long gone are the days where all our data could fit on a two-megabyte floppy disk. In today’s information-based society, the increasing volume of information being handled demands that we switch to memory options with the lowest power consumption and highest capacity possible. Magnetoresistive Random Access Memory (MRAM) is part of the next generation of storage devices expected to meet these needs. Researchers at the Advanced Institute for Materials Research (WPI-AIMR) have investigated a cobalt-manganese-iron alloy thin film that demonstrates…
In the search for new materials that can enable more efficient electronics, scientists are exploring so-called 2-D materials. These are sheets of just one atom thick, that may have all kinds of interesting electronic properties. If two sheets are placed on top of each other at specific angles, this may lead to new properties such as superconductivity. University of Groningen materials scientist Antonija Grubišić-Čabo and her colleagues studied such a ‘twisted’ material and discovered that it defied theoretical predictions. Together…
How simulations help manufacturing of modern displays. Modern materials must be recyclable and sustainable. Consumer electronics is no exception, with organic light-emitting diodes (OLEDs) taking over modern televisions and portable device displays. However, the development of suitable materials – from the synthesis of molecules to the production of display components – is very time-consuming. Scientists led by Denis Andrienko of the Max Planck Institute for Polymer Research and Falk May from Display Solutions at Merck have now developed a simulation…
“Neurons that fire together, wire together” describes the neural plasticity seen in human brains, but neurons grown in a dish don’t seem to follow these rules. Neurons that are cultured in-vitro form random and meaningless networks that all fire together. They don’t accurately represent how a real brain would learn, so we can only draw limited conclusions from studying it. But what if we could develop in-vitro neurons that actually behaved more naturally? A research team at Tohoku University has…
