A CMOS-based chip that integrates silicon quantum dots and multiplexed readout electronics
Researchers at École Polytechnique Fédérale de Lausanne (EPFL) and the Hitachi Cambridge Laboratory have recently designed an integrated circuit (IC) that integrates silicon quantum dots with conventional readout electronics. This chip, introduced in a paper published...
New insights about the toxicity of smoke produced by home stoves and power plants
The color of smoke coming out from chimneys can vary greatly based on its source and how it is produced. For instance, small coal or biomass stoves typically release dense, black smoke, while power generation plants produce lighter-colored plumes of smoke.
A four-megabit nvCIM macro for edge AI devices
Edge AI devices, systems that combine artificial intelligence (AI) and edge computing techniques, are becoming an essential part of the rapidly growing Internet of Things (IoT) ecosystem. These devices include smart speakers, smart phones, robots, self-driven cars,...
A model that can create realistic animations of talking faces
In recent years, computer-generated animations of animals and humans have become increasingly detailed and realistic. Nonetheless, producing convincing animations of a character's face as it's talking remains a key challenge, as it typically entails the successful...
A wafer-scale van der Waals dielectric based on an inorganic molecular crystal film
Van der Waals (vdW) dielectrics, materials with dielectric properties and affected by van der Waals forces, are commonly integrated within electronic devices, as they can help to preserve the properties of 2D semiconducting materials. So far, however, fabricating...
New fuel cells that can operate at temperatures between -20 to 200°C
Proton exchange membrane fuel cells (PEMFCs) are power cells that can transform the chemical energy produced during the electrochemical reaction between hydrogen and oxygen into electrical energy. While these cells could be highly promising energy solutions, most of...
Study: Chemical nature of defects that cause trap states in metal halide perovskite solar cells
In recent years, engineers worldwide have been working to create alternative and sustainable energy solutions, such as solar cells. Solar cells made of perovskites, a class of semiconductors with a characteristic structure and advantageous properties, are among the...
A framework to optimize the efficiency and comfort of robot-assisted feeding systems
Robots could be invaluable allies for older adults and people with physical disabilities, as they could assist them in their day-to-day life and reduce their reliance on human carers. A type of robotic systems that could be particularly helpful are assisted feeding or...
A new framework that could simplify imitation learning in robotics
Over the past few decades, computer scientists have been trying to train robots to tackle a variety of tasks, including house chores and manufacturing processes. One of the most renowned strategies used to train robots on manual tasks is imitation learning.
