In its EV policy rolled out on 7 August 2020, the Delhi government is targeting for EVs to account for 25% of vehicle sales by 2025. With this policy, Delhi also became the first state in the country to fully exempt EVs from road tax and registration fees.A conductive polymer covering known as HOS-PFM, developed by Berkeley Lab researchers, may enable more potent, long-lasting lithium-ion batteries for electric vehicles."The advance opens up a new approach to developing EV batteries that are more affordable and easy to…

Berkeley Lab researchers demonstrated that the HOS-PFM coating significantly prevents aluminum-based electrodes from degrading during battery cycling while delivering high battery capacity over 300 cycles.

Engineers at ETH Zurich have developed a versatile new material that should help in the ongoing battle against corrosion for buildings and vehicles. The polymer coating not only protects against corrosion, but highlights cracks as they form, automatically repairs damage to itself, and can be recycled at the end of its life.Corrosion will eventually affect pretty much everything humans build, from skyscrapers and bridges to planes, trains and automobiles. Developing new corrosion-resistant materials and coatings is a…

Chronic diabetic skin wounds are notoriously slow to heal, sometimes becoming so infected that amputations are required. A newly identified polymer could help keep that from happening, by radically boosting the healing process.In a study conducted at the University of Nottingham, a team led by Prof. Amir Ghaemmaghami started out by screening 315 different polymers, analyzing the chemical makeup of each one. The scientists were looking for polymers that promoted the activity of immune cells and fibroblasts, the latter…
