Ethereum, currently the most widely utilized smart contracts platform, anchors the security of myriad smartcontracts upon its own robustness. Its foundational peer-to-peer network facilitates a dependable node connectionmechanism, whereas an efficient data-sharing protocol constitutes as the bedrock of Blockchain network *** this paper, we propose NodeHunter, an Ethereum network detector implemented through the application ofsimulation technology, which is capable of aggregating all node records within the network and the interconnectednessbetween them. Utilizing this connection information, NodeHunter can procure more comprehensive insightsfor network status analysis compared to preceding detection methodologies. Throughout a three-month period ofunbroken surveillance of the Ethereum network, we obtained an excess of two million node records along with overone hundred million node acquaintances. Analysis of the gathered data revealed that an alarming 49% or more ofthese node records were maliciously forged.

The major impediment to the additional industrialization of water splitting is the high cost of the co-catalyst made of noble metals and the sacrificial reagent.A binary photocatalytic system,consisting of B-doped g-C3N4nanosheets (Cu20@BCN-X) and atomically accurate copper clusters,is designed in this *** copper clusters serve as co-catalysts for H2evolution and exhibit Pt-like activity,whereas the nanosheets serve as carriers and semiconductor components for *** binary system,created using simple techniques,demonstrates hydrogen bonding interactions that promote synergistic effects and efficient binding and charge transfer across the interface between the two *** position manipulation of carbon nitride nanosheets demonstrates a Z-scheme charge transfer mechanism between the nanosheets and copper *** photocatalytic system can accomplish the photocatalytic overall water splitting process (259.9μmol g-1h-1of H2and129.4μmol g-1h-1of O2) without using sacrificial agents or noble metal *** work lays the foundation for the design of overall water splitting catalysts by precisely manipulating the energy levels,and it also paves the way for commercialized photocatalytic catalysts that do not require noble metals or sacrificial chemicals.

伊丽莎白·毕肖普的诗歌多以日常生活为主题。诗人通过对生活空间和生活实践的细致描写,揭示现代化对日常生活造成的异化。以毕肖普诗歌中呈现的日常生活为切入点,结合亨利·列斐伏尔的日常生活批判理论,有助于探究诗歌中异化的日常生活及其救赎方式。毕肖普在诗歌中揭露并批判了资本主义制度与现代工业社会存在的种种虚伪与不公,并将艺术化的生活风格以及来自生活的梦境、想象与记忆作为可能救赎异化生活的途径。毕肖普在诗歌中塑造了一种崭新的理想生活秩序,试图重建现代人得以栖息的精神家园。

针对光刻机等高精确度定位平台无摩擦、无接触、无噪声需求,提出一种采用动子无源型平移和悬浮一体化Halbach磁悬浮永磁直线电机以实现定位平台的无摩擦悬浮及长距离定位运动。为了精确分析该类电机的悬浮力和推力特性,提出一种考虑动子永磁体端部效应的电机磁场解析模型并采用傅里叶分解法得到Halbach阵列永磁体磁场解析式。基于此磁场解析模型,通过洛伦兹力法得到了动子电磁力解析模型,并基于正交分解法推导了电机悬浮力和推力解耦的电磁力模型。结合有限元仿真对建立的电磁模型进行了对比验证,在此基础上,设计并制作了一台10极12槽样机,通过搭建实验平台进行推力和悬浮力测试,将实验测试值与有限元仿真值和解析值对比验证了所提出方法的准确性和快速性。

Mn(Ⅲ)是锰氧化还原循环中电子传递的中间体,广泛参与陆地和海洋生态系统中的碳、铁和硫的地球化学循环.近年来在厌氧、微氧和有氧水环境中陆续发现了Mn(Ⅲ)有机络合物存在,研究地下水环境中Mn(Ⅲ)-腐殖质胶体的形成机制与行为特征对于认识锰的地球化学循环及其影响的营养物和污染物的迁移转化机制具有重要意义.通过开展批实验,探讨氧气条件、腐殖质浓度和有机质种类对Mn(Ⅲ)-腐殖质胶体形成的影响,并结合FTIR、XRD、XPS、TEM多种手段表征其理化性质与稳定性.研究发现:厌氧或有氧-厌氧环境有利于Mn(Ⅲ)-腐殖质胶体形成,Mn(Ⅲ)-腐殖质的络合程度随着腐殖质浓度的升高而增强,富里酸更容易与Mn(Ⅲ)络合,但形成的胶体稳定性较Mn(Ⅲ)-胡敏酸胶体差.Mn(Ⅲ)-腐殖质胶体呈无定形形态,腐殖质上的羧基等含氧官能团与Mn(Ⅲ)形成内球络合物,可减缓Mn(Ⅲ)歧化程度.Mn(Ⅲ)-腐殖质胶体具有氧化和吸附能力,对地下水中污染物的迁移转化具有重要的环境意义.
