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.
Supported catalysts are widely used in various chemical processes. However, most catalysts perform well only for specific chemical reactions, necessitating new methods to diversify and improve performance. Now, researchers have developed an innovative gas-switch-triggered reduction method for impregnation-based synthesis of supported catalysts, consisting of multiple alloyed metals. This method is simple, scalable and can be integrated easily into industrial processes, paving the way for advanced catalysts for more sustainable chemical synthesis.
Seawater is not just a source of salt and water; but it contains a rich variety of ions that benefit to electrocatalytic reactions. This review article provides a timely appraisal of how ions in seawater can be harnessed to drive and enhance electrochemical processes. It identifies key mechanic insights, material design strategies, and future research directions to accelerate the transition from laboratory scale seawater electrocatalysis to real-world electrochemical applications.
