Global warming and imbalances in nitrogen (N)-phosphorus (P) ratios due to increased human activity have had significant impacts on coral reef ecosystems. However, the underlying mechanisms of these impacts remain poorly understood. In this study, a controlled experiment was conducted on Acropora hyacinthus treated with different P concentrations at high temperature (30 °C) and high N level (9 μM nitrate), which was analyzed in terms of physical observations and physiological indices, as well as photosynthetic activity and fatty acid composition.

In this study, taking the oxygen reduction reaction on a metal electrode in aqueous solution as an example, using accurate molecular dynamic simulations, we propose a novel long-range regulation strategy in which midinfrared stimulation (MIRS) with a frequency of approximately 1,000 cm is applied to nonthermally induce the structural transition of interfacial water from an ordered to disordered state, facilitating the access of oxygen molecules to metal surfaces at room temperature and increasing the oxygen reduction activity 50-fold. Impressively, the theoretical prediction is confirmed by the experimental observation of a significant discharge voltage increase in zinc-air batteries under MIRS.
