Safe, efficient, and economical light-absorbing (photovoltaic) technology is key to developing the next generation of solar cells. Cu2ZnSn(S,Se)4 (CZTSSe) photovoltaics—using the easily accessible elements copper, zinc, tin, and sulfur and/or selenium—hold great promise thanks to […]
When artificial intelligence systems began acing long-standing academic assessments, researchers realized they had a problem: the tests were too easy. Popular evaluations, such as the Massive Multitask Language Understanding (MMLU) exam, once considered formidable, are […]
Many governments and businesses worldwide have been trying to devise effective initiatives aimed at mitigating climate change and global warming. So far, their primary focus has been to reduce the emission of carbon dioxide (CO2), […]
Tech titan Amazon is working to step out of Nvidia’s shadow with custom “Trainium” chips designed specially for machine learning as billions of dollars are poured into artificial intelligence (AI).This article is brought to you […]
High-frequency magnetic characteristics are essential for improving the efficiency, miniaturization, and operating frequency of power conversion devices such as power supply circuits, inductors, and transformers. However, conventional measurement methods face two major challenges. First, generating […]
Large-capacity rechargeable batteries capable of sustaining repeated charge-discharge cycles are expected to become core technologies for electric vehicles and other elements of an electrified society. However, current systems often rely on costly metals such as […]
A research team in China has developed an electrolyte using monofluorinated hydrofluorocarbon (HFC) solvents capable of achieving energy densities higher than 700 Wh kg−1 at room temperature and about 400 Wh kg−1 at −50 °C, a significant improvement over current […]
A research team affiliated with UNIST has unveiled a novel dry-process manufacturing method for thick electrodes aimed at enhancing electric vehicle (EV) driving range while reducing battery production costs. Professor Won-Jin Kwak of the School […]
Emergency evacuations during natural disasters like earthquakes and tsunamis increasingly rely on advanced technology to effectively assess real-time crowd movement and points of congestion. Disaster-preparedness involves the development of an optimized technology that is easy […]
In the era of climate crisis, hydrogen vehicles are emerging as an alternative for eco-friendly mobility. However, the fuel cell, known as the “heart of the hydrogen car,” still faces limitations of high cost and […]
