Researchers introduce transparent optical imager with near-infrared sensitivity and touchless interface
Most existing devices are operated via the sense of touch, either via touchscreens or mouse, remote controls, keyboards, and other equipment. Some engineers, however, have been trying to introduce alternative interfaces that do not require users to touch anything, as...
Evaluating the ability of ChatGPT and other large language models to detect fake news
Large language models (LLMs) are an evolution of natural language processing (NLP) techniques that can rapidly generate texts closely resembling those written by humans and complete other simple language-related tasks. These models have become increasingly popular...
A strategy to reduce defects in inverted perovskite solar cells and improve their performance
Perovskites, a class of materials with a characteristic crystal structure, have proved to be very promising for the fabrication of solar cells and photovoltaics. One of these materials is lead triodide (FAPbI3), a perovskite that exhibits a long carrier lifetime and a...
A large dataset to train machine learning models for aerial vehicle design
Designing reliable aircraft can be both challenging and time-consuming, as it often entails several steps and analyses. Deep learning models could potentially help to speed up aircraft design and deployment, helping developers to identify the most promising solutions...
A new neural machine code to program reservoir computers
Reservoir computing is a promising computational framework based on recurrent neural networks (RNNs), which essentially maps input data onto a high-dimensional computational space, keeping some parameters of artificial neural networks (ANNs) fixed while updating...
A strategy to create highly performing cobalt-free cathodes for lithium-ion batteries
Lithium-ion (Li-ion) batteries, rechargeable batteries that can store energy via the reversible reduction of lithium ions, are among the most widespread battery technologies, due to their remarkable performance and extended life cycle. Many existing and emerging...
Grooved electrodes could improve the performance of proton-exchange membrane fuel cells
Proton-exchange membrane fuel cells (PEMFCs) are a promising energy solution for reducing carbon emissions in the transport sector. As suggested by their name, these cells contain a proton-conducting membrane based on polymer materials that serves as an electrolyte....
Evaluating the energy consumption of flapping-wing flying robots
Unmanned aerial vehicles (UAVs), commonly known as drones, have already proved to be highly promising for tackling numerous real-world problems, for instance allowing users to take aerial images, monitor remote or natural environments, deliver parcels, or assisting...
