Lithium-based batteries are used to power most existing electric vehicles, yet the amount of time they can keep a vehicle going before they need to be recharged is still somewhat limited. In the future, high-nickel layered oxide cathode materials could help to...
Lithium-rich transition metal oxide (Li1+XM1-XO2) cathodes have potential for use in Li-ion batteries, powering electronic devices and electric vehicles. These cathodes have a high energy density, typically above 900 Wh kg-1, yet they currently also come with...
Photovoltaic (PV) cells, which can generate energy from the sun, could be very useful in tackling the current environmental crisis. Perovskite PV cells, cells made of metal halide perovskite semiconductors, have recently proved to be particularly promising, as...
Researchers at UC Berkeley and Facebook AI Research have recently developed a new approach for robot navigation in unknown environments. Their approach, presented in a paper pre-published on arXiv, combines model-based control techniques with learning-based perception.
When it comes to predicting the costs of new energy systems and technologies, researchers must consider learning rates, which are estimated measures of technological progress. In fact, technological advances are typically associated with higher technological...
In recent years, research teams worldwide have developed new methods for simultaneous localization and mapping (SLAM). These techniques can be used to construct or update maps of a given environment in real time, while simultaneously tracking an artificial agent or...
Conformable imagers are flexible electronic components that can be placed in direct contact with a human user's skin, recording his/her vital signs or other biological information. Over the past few years, these imagers have become widely used, particularly for...
2-D semiconductors could have very useful applications, particularly as channel materials for low-power transistors. These materials display very high mobility at extreme thicknesses, which makes them particularly promising alternatives to silicon in the fabrication...
Two researchers at Shanghai University of Electric Power have recently developed and evaluated new neural network models for facial expression recognition (FER) in the wild. Their study, published in Elsevier's Neurocomputing journal, presents three models of...
Researchers at the Robert Bosch center for cyber physical systems in Bangalore, India, have recently proposed a simulation framework to systematically study the effects of spinal joint actuation on the locomotion performance of quadruped robots. In their study,...
