The global nitrogen cycle holds immense importance due to its crucial role in supporting life, supplying vital nutrients for plant growth, preserving environmental balance, and enabling the proper functioning of ecosystems. However, human activities frequently disrupt this cycle, leading to the accumulation of nitrates and nitrites in water bodies. This accumulation causes environmental pollution and health risks. Traditional methods for treating nitrogen pollution, including biological, physical, and chemical approaches, have inherent limitations. In recent years, electrocatalysis has emerged as a promising and sustainable approach for nitrogen management. This technology offers superior efficiency, high selectivity, and environmental *** not only enables accurate detection of nitrogen pollutants in the environment but also facilitates their conversion into harmless nitrogen gas. Moreover, recent advancements have focused on the upcycling of nitrogen pollutants into valuable compounds,such as ammonia and urea. In this comprehensive review, we showcase the applications of electrocatalysis in sustainable nitrogen management. Specifically, we highlight its use in the sensing, removal, and upcycling of major nitrogen pollutants,including nitrate（NO3-）, nitrite（NO2-）, and nitric oxide（NO）. We discuss the use of catalysts, such as Pd alloys, Cu-based, and Fe-based materials, in electrochemical sensing and catalysis. Additionally, we explore recent advancements in the conversion of nitrogen pollutants into valuable compounds like ammonia and urea. The review also addresses current challenges and future opportunities in the field, including innovations in sensor and catalyst design, as well as large-scale treatment strategies. We anticipate that these perspectives will provide profound insights for effective nitrogen pollution control and sustainable utilization of nitrogen resources.

Thrombin blockers have been shown to be effective for various pathological conditions， but their use is limited due to the potential for serious bleeding adverse effects. This study introduced a novel bioactive peptide (P-2-CG) from oyster， that mitigated thrombin-mediated barrier dysfunction and prothrombotic phenotypes in human pulmonary microvascular endothelial cells (HPMECs). P-2-CG significantly attenuated the increase in endothelial monolayer permeability induced by thrombin through the possible attenuation of RhoA activation and it promoted barrier recovery by enhancing endothelial cell adhesion. Additionally， P-2-CG was found to decrease the pro-thrombotic phenotype induced by thrombin in HPMEC by reducing the extrinsic trigger TF mRNA expression， which resulted in prolonged plasma clotting time， decreased FXa activation， and reduced thrombin generation. Moreover， P-2-CG inhibited thrombosis efficiently by blocking ICAM-1 and VCAM-1 expression via tyrosine phosphorylation of RelA/p65. P-2-CG inhibits thrombin mediated inflammation and provides a potential therapeutic option for treating endothelial dysfunction and thrombosis.

针对变压器油中溶解气体序列波动性、随机性较强难以精确预测的问题,提出一种基于最优变分模态分解(optimal variational mode decomposition,OVMD)、混合型鲸鱼优化算法(hybrid whale optimization algorithm,HWOA)和核极限学习机(kernel extreme learning machine,KELM)的组合预测模型。首先,运用OVMD获取最优分解参数,并将原始序列分解为一系列相对平稳的分量;其次,通过在鲸鱼种群中融入混沌映射、非线性收敛参数、自适应权重因子和改进的算术优化算法提出HWOA算法,并利用测试函数验证HWOA算法的优越性;然后,对各分量分别构建KELM预测模型,使用HWOA优化KELM的关键参数。最后,将各分量的预测结果叠加重构,得到最终预测结果。案例分析表明,所提模型对变压器正常和异常案例预测的决定系数分别可达97.7%和93.46%,相较于现存方法,该模型具有更好的准确性和适应性,可为电力变压器运维管理提供有利技术支撑。

为提高风电功率预测精度,提出基于自适应二次模态分解(QMD)、卷积神经网络(CNN)与双向长短期记忆网络(BiLSTM)的超短期风电功率预测模型。针对风电功率的波动性,利用改进的完全自适应噪声集成经验模态分解方法(ICEEMDAN)对风电功率数据进行分解。引入麻雀搜索算法(SSA)对变分模态分解(VMD)的分解数量与惩罚因子进行优化,使VMD具有自适应性。将ICEEMDAN分解得到的高频分量I_(1)用SSA-VMD进行第二次分解,降低序列不平稳度。同时,构建包含2层池化层的CNN网络进行特征提取与BiLSTM网络的超短期预测模型,最终的风电功率即为各子序列预测结果之和。通过算例分析进行实验表明,所提风电功率预测方法的预测精度优于其他模型,验证了预测模型的优越性。
