The energy transition poses challenges for countries, cities, and regions. The use of sustainable sources of energy is key to halting climate change. At the same time, the costs of the energy system must not spiral out of control, and supply security must be ensured. These three aspects—sustainability, costs, and...

Grab a coffee and your car is fully charged—this is how many people envision the future of mobility. But today's batteries still fall short of this ideal. While modern lithium–ion batteries can charge from 20% to 80% in about 20 to 30 minutes, a full charge takes considerably longer—and fast...

A research team led by the Institute of Materials Science of Barcelona (ICMAB-CSIC) has demonstrated a new induction-based mechanism that enables partial self-recharging in batteries, using a symmetric iron-based configuration as a proof of concept. The study, published in Electrochimica Acta, lays the groundwork for future battery systems that integrate...

Buildings adorned with plants are an increasingly familiar sight in cities worldwide. These "green walls" are generally created using metal frames that support plastic plates, onto which pre-grown plants are inserted. These plants are able to survive without soil because they're sustained by nutrient-packed rolls of felt and artificial sprinklers....

The ocean serves as Earth's largest dynamic carbon sink, absorbing 400 million tons of carbon dioxide (CO₂) annually through continuous exchange with the atmosphere. Researchers at Yale have now developed an efficient system to extract and convert dissolved CO₂ into clean fuels and useful industrial feedstock....
