For the porous-membrane-based osmotic energy generator, the potential synergistic enhancement mechanism of various key parameters is still controversial, especially because optimizing the trade-off between permeability and selectivity is still a challenge. Here, to construct a permeability and selectivity synergistically enhanced osmotic energy generator, the two-dimensional porous membranes with tunable charge density are prepared by inserting sulfonated polyether sulfone into graphene oxide. Influences of charge density and pore size on the ion transport are explored, and the ionic behaviors in the channel are calculated by numerical simulations. The mechanism of ion transport in the process is studied in depth, and the fundamental principles of energy conversion are revealed. The results demonstrate that charge density and pore size should be matched to construct the optimal ion channel. This collaborative enhancement strategy of permeability and selectivity has significantly improved the output power in osmotic energy generation; compared to the pure graphene oxide membrane, the composite membrane presents almost 20 times improvement. Transmembrane properties of ions are crucial for osmotic energy conversion. In this study, to achieve synergistic enhancement of permeability and selectivity, the mechanism of charge density and pore size in ion transport are studied in-depth. Results of the experiment and theoretical calculation demonstrate that the charge density and pore size should be matched to construct the optimal ion channel. This collaborative enhancement strategy of permeability and selectivity is expected to promote the utilization of clean energy in the future. image

人口负增长叠加快速老龄化将对现收现付型的养老保险制度产生巨大冲击。在当前人口负增长不可逆的趋势下,制度赡养率攀升、制度参数协调性失灵、制度代际负担不公平、制度模式取向陷入困境将给养老保险制度的安全可持续运行带来挑战。为应对这些挑战,养老保险制度的改革要遵循责任主体多元化、制度参数协调化、设计理念效率化、待遇调节机制精准化等理念导向,才能顺应人口环境变化的客观要求。可采取推进渐进式延迟退休政策实施、完善“三支柱”养老保险体系、建立稳健的“储备型”养老基金、提高制度赡养能力以及实施统筹层次全国化等举措,以期实现我国养老保险制度安全可持续运行。

已有火龙果检测方法仅针对单一性能指标,难以满足农业真实场景的需要,为此提出了一种精准高效的火龙果品质与成熟度双指标检测方法。首先,利用自适应鉴别器增强的样式生成对抗网络扩充火龙果图像,建立复杂环境火龙果数据集。采用伽马变换进行图像增强,凸显火龙果特征,降低光照环境的影响。其次,提出了YOLO v7-RA模型。通过设计ELAN_R3替代ELAN(Efficient layer aggregation network)模块,减少主干网络对重复特征的提取,增强模型对细粒度特征关注度,提高双指标检测准确率。融入混合注意力机制(Mixture of self-attention and convolution,ACmix),增强模型对特征的提取和整合能力,降低杂乱背景信息干扰。最后,通过实验验证了YOLO v7-RA模型的检测性能。实验结果表明,该方法精准率为97.4%,召回率为97.7%,mAP_(0.5)为96.2%,FSP为74 f/s,实现了检测精度与检测速度的均衡。即使在遮挡情况下,YOLO v7-RA模型检测精准率仍达到91.4%,具有较好泛化能力,能够为火龙果智能化采摘的发展提供技术支持。
