One of the most promising technologies is perovskite solar cells. They are highly efficient at converting sunlight into electricity, can be manufactured as thin and flexible devices, and require less energy and lower production ...

Sodium-ion batteries (SIBs) are increasingly popular alternatives to lithium-ion batteries. Sodium (Na) is much more abundant in Earth's crust than lithium, creating an opportunity for lower costs. In addition, SIBs offer ...

Chinese scientists have developed a method that could facilitate the large-scale production of high-efficiency perovskite solar cells. The method employs a multidentate anchoring molecule-assisted co-deposition strategy to ...

Researchers from the National University of Singapore (NUS) College of Design and Engineering (CDE), led by Professor Heng Chye Kiang (NUS Department of Architecture), have developed a computational framework for reconstructing ...

The ability to change focus instantly is something most people take for granted. Every day, our eyes effortlessly switch between reading a book, recognizing a face across the room or watching a bird fly overhead. Replicating ...

Subscriber Identity Modules (SIMs), secure elements used to connect devices to a mobile network, can pose severe security risks when compromised. A malicious SIM could allow attackers to gather information about a device, ...

Most batteries spend more than 70% of their lifetime at rest. Yet few studies have examined calendar aging, which is how a battery degrades when it is neither charging nor being used.

Researchers at Aalto University, together with international partners, have developed the most accurate model yet of how humans read. The new model uses reinforcement learning, a type of AI used in robotics, to explain—and ...

Large language models (LLMs), the models that underpin platforms such as ChatGPT and Gemini, are now used daily by more than a billion people worldwide. Some computer scientists have also been combining several of these models ...

Why do we breeze through some sentences in a book or article but have to reread others to comprehend their meaning? A team of linguists and data scientists has found a partial answer in AI—some of this processing parallels ...

Recent advances in miniaturized and portable electronics, particularly wearable and flexible devices, have increased the demand for self-powered sensing technologies. Among these, triboelectric nanogenerators (TENGs) have ...

Cornell researchers are using artificial intelligence to speed the search for better battery materials while using a creative approach to chemistry to expand the design space for electrolytes, unlocking new possibilities ...
