When it comes to fighting climate change, electric buses are a triple threat: they encourage energy-efficient levels of urban population density; take dozens of polluting vehicles off the street; and don’t release tailpipe emissions. The popularity of this approach presents its own challenges, however: cities can deploy electric buses faster than their power grids can … Read more
Active droplet electrotaxis in a microchannel, with an increasing electric field. Credit: Physical Review Letters (2024). DOI: 10.1103/PhysRevLett.133.158301 In a new study in Physical Review Letters, scientists have demonstrated a method to control artificial microswimmers using electric fields and fluid flow. These microscopic droplets could pave the way for targeted drug delivery and microrobotics. In … Read more
Accurately diagnosing the state of electric vehicle (EV) batteries is essential for their efficient management and safe use. KAIST researchers have developed a new technology that can diagnose and monitor the state of batteries with high precision using only small amounts of current, which is expected to maximize the batteries’ long-term stability and efficiency. KAIST … Read more
Canada says it will impose a 100% import duty on imports of Chinese-made electric vehicles (EVs) after similar announcements by the US and EU. The country also plans to impose 25% tariffs on Chinese steel and aluminum. Canada and its Western allies accuse China of subsidizing its EV industry, giving its carmakers an unfair advantage. … Read more
