The secret of the magic gourd(I): biomass from various organizations of ourds as a sustainable source for high-performance supercapacitors

The classic cartoon “Calabash Brothers” describes a story of seven brothers born from a magic gourd uniting to defeat powerful enemies. In order to explore the secret of the magic gourd, several transition metals were used to synthesize metal silicates（CMSi） by planted gourd leaves（GLs） and then the C-MSi materials were used to fabricate supercapacitor electrodes and devices with superior electrochemical performance. By integrating theoretical calculations and experimental results, the supercapacitor electrodes and devices obtained from the combination of transition metals with amorphous carbon exhibit superior electrochemical performance. In detail, in the three-electrode system, the NaOH etched materials（C-MSi） exhibited better electrochemical performance(for instance, as for C-CdSi, 607 F g-1at 0.5 A g-1and the capacitance retention of 98.2% after 10,000cycles) than the unetched ones（i-C-MSi）. Hybrid supercapacitor（HSC） devices also achieve very excellent electrochemical properties. Take C-CdSi//AC as an example, the areal specific capacitance with 691 m F cm-2at 2 mA cm-2, the energy density with 5.04 Wh m-2at the power density of 22.2 W m-2and the cycle stability with 87.3% after 6,000 cycles. This approach is very versatile and was also applied to produce many hierarchically structured metal-silicate materials of other biomass precursors,including roots, vines, flowers, fruits and seeds of the planted gourds. Thus, it is a potential way to prepare transition metal silicates using biomaterials for the enhancement of electrochemical performance and improvement of energy storage and conversion. Also, this paper preliminarily reveals the secret of the magic gourd.

针对风电介入下的多区域互联电力系统,提出一种分布式经济模型预测负荷频率控制策略.通过将大规模互联电力系统分解成若干个动态耦合的子系统,这些子系统能够利用网络交流并共享信息,使得各区域的控制器实现各自优化问题的求解.同时,在满足状态约束和控制输入约束的前提下,遵循传统火力发电优先、风力发电配合的原则,通过在线求解优化问题,实现风电介入下的多区域互联电力系统的负荷频率控制.为了提高系统整体运行经济性,所提出的分布式经济模型预测控制器将负荷调频成本、燃料消耗成本以及风力发电成本等经济性指标考虑在内.仿真结果表明,在阶跃负荷扰动下,所设计的控制器不仅可以满足调频要求,在降低计算负担和提高经济性能方面也具有一定优势.

该文研究空地协同通信感知一体化系统,其中无人车(UGV)基站和无人机(UAV)中继集群组成空地协同网络,为用户提供通信服务,同时对目标区域进行探测感知。在更加准确的莱斯衰落信道模型下,研究联合优化无人机集群的通信感知关联、发射功率和飞行轨迹以及无人车基站的发射功率和行进轨迹,在目标区域感知频率和有效感知功率阈值的约束下,最大化用户最小平均通信速率。为了解决变量高度耦合且非凸的整数优化问题,首先利用块坐标下降法将原问题分解成4个子问题;接着引入松弛变量并将整数约束转化为惩罚项,然后证明莱斯信道下的有效感知功率是关于轨迹变量和松弛变量凸复合函数的联合凸函数;再利用连续凸优化法处理非凸项,并提出一种双层迭代算法高效求解次优解。仿真结果表明,与几种基准方案相比,所提优化算法在相同感知性能下,提高了用户最小平均通信速率,更好地实现了通信与感知性能之间的权衡,并具有良好的收敛性。

Inulin alleviates HFD-induced NAFLD by hepatic macrophage polarization and lipid metabolism via gut-liver axis

引用

Food Science and Human Wellness 2024年

作者： Wei Song Jinhong Hu Lina Zhu Bing Chen Lingling Li Xiaole cui Ting Zhang Yaxing miao Kaixin Su Changchun Liu Yane Luo Tianli Yue College of Food Science and Technology， Laboratory of Nutritional and Healthy Food-Individuation Manufacturing Engineering， Research Center of Food Safety Risk Assessment and Control， Northwest University

Long-term intake of high-fat diet (HFD) leads to systemic hypo-inflammation， which is involved in the pathogenesis of many liver diseases. The aim of this study was to evaluate the interventional effect of inulin addition on HFD-induced non-alcoholic fatty liver disease (NAFLD). Here， we assessed liver inflammation and lipid metabolism by ELISA kits and real-time quantitative polymerase chain reaction (qPCR)， and explored its relationship with intestinal flora and metabolites by 16S rDNA gene sequencing and untargeted metabolomics. In addition， we determined the effect of the inositol-requiring enzyme-1α (IRE1α-XBP1) pathway on liver macrophage polarization by flow cytometry. In conclusion， our study has demonstrated that inulin ameliorates high levels of bile acids and colonic immune disorders induced by HFD， and improves hepatic macrophage polarization and hepatic lipid metabolism via the intestine-hepatic axis， thus providing a mechanistic basis for therapeutic approaches to modulate bile acids to improve colonic inflammation and nonalcoholic fatty liver disease.
