Batteries are becoming more powerful and cost-efficient thanks to the accelerated transport of lithium ions through metal fleeces. A team led by Joachim Spatz at the Max Planck Institute for Medical Research has demonstrated that nonwoven electrodes offer significantly higher energy density than conventional foil electrodes. One key reason is that ions move particularly quickly through a Helmholtz layer that forms on the metal surface.
battery electrodes: The energy density of the anode can be increased by up to 85 per

Polluted air shortens the lifespan of Europeans by about two years: a re-evaluation of the health risks associated with air pollution shows an unexpected high mortality risk, especially due to cardiovascular diseases
According to the study, around 120 people per 100,000 population die prematurely

Diagnosing common diseases like diabetes, high blood lipid levels, metabolic disorders, high blood pressure, and metabolic syndrome is set to become easier with infrared fingerprinting and machine learning. This innovative diagnostic method was developed by a team led by Mihaela Žigman from the Max Planck Institute of Quantum Optics.

Researchers at the Max Planck Institute for Human Development have critically examined the basis for a frequently cited figure: that people make more than 200 unconscious decisions about food every day. This figure has circulated in scientific publications, the media, and health promotion campaigns for nearly 20 years without ever being empirically validated. An article published in the journal Appetite shows why a more nuanced view of eating behavior is needed.
