Tech Xplore / Isotropic MOF coating reduces side reactions to boost stability of solid-state Na batteries
In recent years, energy engineers have been trying to design new reliable batteries that can store more energy and allow electronics to operate for longer periods of time before they need to be charged. Some of the most promising ...
Phys.org / Simulations hint at new strongly correlated states of matter in ultracold polar molecules
Bose-Einstein condensates (BECs) are fascinating states of matter that emerge when atoms or molecules are cooled to extremely low temperatures just slightly above absolute zero (0 K). In 2023, physicists at Columbia University ...
Medical Xpress / Family and peer conflicts predict teenage mental health issues, study finds
Identifying the factors that contribute to psychopathology and increase the risk of experiencing specific mental health conditions is a long-standing goal for many psychology researchers. While past studies have highlighted ...
Tech Xplore / Novel carbon nanotube-based transistors reach THz frequencies
Carbon nanotubes (CNTs), cylindrical nanostructures made of carbon atoms arranged in a hexagonal lattice, have proved to be promising for the fabrication of various electronic devices. In fact, these structures exhibit outstanding ...
Tech Xplore / New organic thin-film tunnel transistors for wearable and other small electronics
To meet the growing demands of flexible and wearable electronic systems, such as smart watches and biomedical sensors, electronics engineers are seeking high-performance transistors that can efficiently modulate electrical ...
Phys.org / Exploring how dark matter alters electron-capture supernovae and the birth of neutron stars
Electron-capture supernovae (ECSNe) are stellar explosions that occur in stars with initial masses around 8–10 times that of the sun. These stars develop oxygen-neon-magnesium cores, which become unstable when electrons are ...
Tech Xplore / Humans and LLMs represent sentences similarly, study finds
Psychologists and behavioral scientists have been trying to understand how people mentally represent, encode and process letters, words and sentences for decades. The introduction of large language models (LLMs) such as ChatGPT, ...
Phys.org / Graphene partially screens van der Waals interactions depending on layer thickness, study reveals
Two-dimensional (2D) materials, which are only a few atoms thick, are known to exhibit unique electrical, mechanical and optical properties, which differ considerably from the properties of bulk materials. Some recent studies ...
Medical Xpress / Study unveils mechanisms driving axonal accumulation of TDP-43 and associated nerve damage in ALS
Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease characterized by progressive muscle wasting and limb paralysis. This neurodegenerative condition results from the gradual destruction of motor neurons, the ...
Medical Xpress / Grid cells create multiple local maps rather than single global system for spatial navigation, study finds
Grid cells are a class of specialized neurons in a brain region called the entorhinal cortex, which is known to support spatial navigation and some memory processes. Past neuroscience studies have found that as humans and ...
Tech Xplore / New Mn-rich cathode could improve sustainability and stability of high-energy Li-ion batteries
Lithium-ion batteries (LiBs) remain the most widely used rechargeable batteries worldwide, powering most portable and consumer electronics. LiBs are also used to power most electric and hybrid vehicles, which are predicted ...
Phys.org / Hybrid metasurface modulates light at low voltages for energy-efficient optics
Metasurfaces are two-dimensional (2D), nanoengineered surfaces that interact strongly with electromagnetic waves and can control light with remarkable precision. These ultra-thin layers can be used to develop a wide range ...
Phys.org / Simplified Sachdev-Ye-Kitaev model simulated on trapped-ion quantum computer
The simulation of strongly interacting many-body systems is a key objective of quantum physics research, as it can help to test the predictions of physics theories and yield new valuable insight. Researchers at Quantinuum, ...
Phys.org / Algorithm precisely quantifies flow of information in complex networks
Networks are systems comprised of two or more connected devices, biological organisms or other components, which typically share information with each other. Understanding how information moves between these connected components, ...
Tech Xplore / Promising medium can capture and convert carbon dioxide, while regenerating itself for reuse
Over the past decades, energy researchers have developed various promising solutions to limit the emission of greenhouse gases and source fuels or other chemicals more sustainably. These solutions include so-called carbon ...
