Published in PLOS Water, the study reveals that phosphate used in such treatment can leak into streams and reshape their chemistry and health

Researchers have achieved a new level of control over the atomic structure of a family of materials known as halide perovskites, creating a finely tuned ‘energy sandwich’ that could transform how solar cells, LEDs and lasers are made.

In a policy brief published in Science, scientists call on European Union for a new approach to protect people and nature from the hidden risks of chemical cocktails.

The Northeastern Pacific Ocean is becoming more acidic faster than other oceans as the water absorbs carbon dioxide from the atmosphere and natural processes feed carbon dioxide up from the deep. The rate of CO2 accumulation is outpacing atmospheric rises and driving acidity to new extremes.

The lithium-ion battery is a new energy storage device widely employed in various fields such as mobile power, electric vehicles, unmanned aerial vehicles, and spacecrafts due to its high energy, high efficiency, lightweight, and environmental friendliness. Understanding the internal mechanism of the battery is of utmost importance. The electrochemical model provides detailed insights into the internal mechanism of lithium batteries and encompasses the single-particle model and the P2D model, as well as enhancements such as thermal coupling, mechanical stress coupling, and electric double-layer capacitive coupling. However, the dispersion effect of capacitors in solid electrolyte interface (SEI) film capacitors and porous electrodes has been basically ignored, which is essential for analyzing the internal mechanism and managing energy conversion in lithium batteries experiencing short-term effects. Furthermore, the determination of the dominant order of the Faraday process and non-Faraday process within a short time period is essential for accurately predicting the lifespan of lithium batteries subjected to high-frequency periodic excitation and assessing performance degradation. While the frequency range of these two processes can be roughly delineated through electrochemical impedance spectroscopy (EIS), the precise transition time of their dominant positions remains uncertain.

Soil moisture is a key factor driving the Earth's water and carbon cycles, but large-scale monitoring has long been hindered by sparse ground observations and model uncertainties. 

Melting sea ice in polar regions is transforming how the oceans move and mix. In a recent study, researchers used a high-resolution climate model to explore how rising CO₂ levels intensify ocean stirring. They found that sea ice loss strengthens currents and turbulence, particularly in the Arctic and Southern Oceans. Such changes are expected to substantially alter the transport of heat, carbon, and nutrient, ultimately affecting polar marine ecosystems under future climate conditions.
