Apr 19, 2024 (Nanowerk News) Scientists at the National Astronomical Observatories of the Chinese Academy of Sciences (NAOC) and their international collaborators have recently developed a new method for efficiently extracting information from galaxy surveys. Their research results were published in Communications Physics ("Extracting high-order cosmological information in galaxy surveys...
To build a better AI helper, start by modeling the irrational behavior of humans
Apr 19, 2024 (Nanowerk News) To build AI systems that can collaborate effectively with humans, it helps to have a good model of human behavior to start with. But humans tend to behave suboptimally when making decisions. This irrationality, which is especially difficult to model, often boils down to computational...
Conducting 2D polymers exhibit electron mobility comparable to graphene
Apr 19, 2024 (Nanowerk News) Professors Kimoon Kim and Ji Hoon Shim along with Dr. Yeonsang Lee from the Department of Chemistry at Pohang University of Science and Technology (POSTECH) and Professor Jun Sung Kim from POSTECH’s Department of Physics and the Center for Artificial Low Dimensional Electronic Systems at...
Energy scientists unravel the mystery of gold’s glow
Apr 19, 2024 (Nanowerk News) Luminescence, or the emission of photons by a substance exposed to light, has been known to occur in semiconductor materials like silicon for hundreds of years. The nanoscale behavior of electrons as they absorb and then re-emit light can tell researchers a great deal about...
disordered structure of battery-like devices improves performance
Apr 19, 2024 (Nanowerk News) The energy density of supercapacitors – battery-like devices that can charge in seconds or a few minutes – can be improved by increasing the ‘messiness’ of their internal structure. Researchers led by the University of Cambridge used experimental and computer modelling techniques to study the...
Accelerating the discovery of new materials via the ion-exchange method
Apr 19, 2024 (Nanowerk News) Tohoku University researchers have unveiled a new means of predicting how to synthesize new materials via the ion-exchange. Based on computer simulations, the method significantly reduces the time and energy required to explore for inorganic materials. Details of their research were published in the journal...
Two-dimensional nanomaterial sets record for expert-defying, counter-intuitive expansion
Apr 18, 2024 (Nanowerk News) It is a common hack to stretch a balloon out to make it easier to inflate. When the balloon stretches, the width crosswise shrinks to the size of a string. Noah Stocek, a PhD student collaborating with Western physicist Giovanni Fanchini, has developed a new...
Imaging structural transformations in 2D materials
Apr 18, 2024 (Nanowerk News) Silicon-based electronics are approaching their physical limitations and new materials are needed to keep up with current technological demands. Two-dimensional (2D) materials have a rich array of properties, including superconductivity and magnetism, and are promising candidates for use in electronic systems, such as transistors. However,...
Metal-organic framework coatings enable simple, reusable water contaminant testing
Apr 18, 2024 (Nanowerk Spotlight) Ensuring the safety of our water supplies requires the ability to detect even trace amounts of pollutants. However, traditional testing methods often involve complex and time-consuming sample preparation steps that hinder timely and efficient monitoring. In pursuit of simpler and more effective solutions, scientists have...
New understanding of energy losses in emerging light source
Apr 18, 2024 (Nanowerk News) The light-emitting electrochemical cell (LEC) can be fabricated in a sustainable and cost-effective way on both rigid and flexible surfaces making it suitable for a broad range of applications, like illumination, healthcare, and signage.
