Optical properties of afterglow luminescent particles (ALPs) in mechanoluminescence (ML) and mechanical quenching (MQ) have attracted great attention for diverse technological applications. A team of researchers from Pohang University of Science and Technology (POSTECH) has garnered attention by developing an optical display technology with ALPs enabling the writing and erasure of messages underwater.

As any percussionist or fidgety pen-tapper can tell you, different materials make different noises when you hit them. Researchers at Drexel University hope this foundational acoustic phenomenon could be the key to the speedy removal of lead water lines that have been poisoning water supplies throughout the country for decades.

A new field promises to usher in a new era of using machine learning and computer vision to tackle small and large-scale questions about the biology of organisms around the globe. The field of imageomics aims to help explore fundamental questions about biological processes on Earth by combining images of living organisms with computer-enabled analysis and discovery.

Quantum computers, which can solve several complex problems exponentially faster than classical computers, are expected to improve artificial intelligence (AI) applications deployed in devices like autonomous vehicles; however, just like their predecessors, quantum computers are vulnerable to adversarial attacks.

Before a robot can grab dishes off a shelf to set the table, it must ensure its gripper and arm won't crash into anything and potentially shatter the fine china. As part of its motion planning process, a robot typically runs "safety check" algorithms that verify its trajectory is collision-free.

In recent years, materials scientists and engineers have introduced increasingly sophisticated materials for robotic and prosthetic applications. This includes a wide range of electronic skins, or e-skins, designed to sense the surrounding environment and artificially reproduce the sense of touch.

Recently, the National Science Open magazine published online a review article by Professor Jiao Shuhong's group from the University of Science and Technology of China and Professor Cheng Tao's team from Suzhou University. The review discussed the preliminary application and huge development potential of artificial intelligence (AI) technology in battery interface research.

A research team has published new research on edge-nitrogen doped porous carbon for energy-storage potassium-ion hybrid capacitors in Energy Material Advances.

Unmanned Aerial Vehicles (UAVs) have received significant attention in recent years across many sectors, such as military, agriculture, construction, and disaster management. These versatile machines offer remote access to hard-to-get or hazardous areas and excellent surveillance capabilities.

Researchers in Sweden unveiled a new concept for producing hydrogen energy more efficiently, splitting water into oxygen and hydrogen without the dangerous risk of mixing the two gases.

Under real-world haze conditions, captured images not only suffer from the haze but also are affected by the noise, which significantly deteriorates the visibility of images. However, most of existing haze removal methods mainly focus on haze degradation and fail to consider noise interference.

If you recently had trouble figuring out if an image of a person is real or generated through artificial intelligence (AI), you're not alone.

At present, viscose textiles are made of biomass from the forest, and there is no such thing as fully recycled viscose. Researchers at Lund University in Sweden have now succeeded in making new viscose—from worn-out cotton sheets.

Holography technology can restore the complete light field information of a recorded object, which has important applications in fields such as biological microscopic imaging and optical micromanipulation.

The result of a new study on the intrinsic dynamics of spatio-temporal processes conducted at the MOX laboratory of the Politecnico di Milano (Department of Mathematics) by Francesco Regazzoni, Stefano Pagani, Matteo Salvador has been published in Nature Communications.

The National Institute of Standards and Technology (NIST) and its collaborators have delivered a small but mighty advancement in timing technology: compact chips that seamlessly convert light into microwaves. This chip could improve GPS, the quality of phone and internet connections, the accuracy of radar and sensing systems, and other technologies that rely on high-precision timing and communication.

Researchers have moved one step closer to making solid-state batteries from lithium and sulfur a practical reality. A team led by engineers at the University of California San Diego developed a new cathode material for solid-state lithium-sulfur batteries that is electrically conductive and structurally healable—features that overcome the limitations of these batteries' current cathodes.

Cornell University researchers have developed a semiconductor chip that will enable ever-smaller devices to operate at the higher frequencies needed for future 6G communication technology.

Rechargeable batteries are great for storing energy and powering electronics from smartphones to electric vehicles. In cold environments, however, they can be more difficult to charge and may even catch on fire.

As the world rushes to make use of the latest wave of AI technologies, one piece of high-tech hardware has become a surprisingly hot commodity: the graphics processing unit, or GPU.
