The design and manufacture of anti-scaling surface is a prospective way to prevent scaling in oil *** this work,a novel superhydrophobic Cu^(2+)-loaded and DTPMPA-modified anodized copper oxide(S-Cu^(2+)/D-ACO)coating was fabricated by modification of 1H,1H,2H,*** valid storing of scale inhibitors at the coating surface and the interfacial release of Cu^(2+)ions contribute to enhancing the anti-scaling of the S-Cu^(2+)/D-ACO *** water contact angle of the S-Cu^(2+)/D-ACO coating is 163.03°and exhibits superhydrophobicity,which makes it difficult for CaCO_(3)to deposit at the surface of the *** will steadily lurk into the inner space,and Cu^(2+)will be loaded at the interface in the form of the DTPMPA:Cu^(2+)*** the deposition of CaCO_(3),the dynamic release of DTPMPA can be realized by transferring DTPMPA:Cu^(2+)to DTPMPA:Ca^(2+).Interestingly,the released Cu^(2+)hinders the active growth of CaCO_(3).After 48 h of scaling,the mass of CaCO_(3)scale at the S-Cu^(2+)/D-ACO coating surface is only 44.1%that of the anodized copper oxide *** excellent anti-scaling performance of the S-Cu^(2+)/D-ACO coating is determined by the synergistic effect of the DTPMPA lurking and dynamic release,as well as the Cu^(2+)inhibition at the interface of superhydrophobic coating and against CaCO_(3)*** research provides a new exploration for designing and fabricating anti-scaling superhydrophobic surface for oil field development.

结合某海上风机单立柱三桩基础,对海上风机灌浆连接段进行轴向承载力试验。共设计四个试验模型,包括两个带剪力键的模型和两个无剪力键的模型。试验结果表明:带剪力键的模型承载力和延性比无剪力键的模型显著提高;受过疲劳荷载的带剪力键模型虽然延性有一定降低,但其承载力仍与未受过疲劳荷载的模型相当。该文还讨论了UK规范、API规范和新旧DNV规范建议的四个灌浆连接段轴向承载力经验公式。各公式之间的对比表明,它们都存在一定的缺点:API规范公式和旧版DNV规范公式形式还不太成熟,而UK规范公式和新版DNV规范公式试验数据参数范围不全。因此,该文最后建议提出一个灌浆连接段界面抗剪强度的新公式,以适应更广泛的工程应用条件。

The advantages and disadvantages of a typical semi-dry flue gas desulfurization （FGD） method are analyzed and a novel semi-dry FGD method of simple and compact system with high efficiency is firstly put forward, named multi-fluid alkaline spray generator FGD method. The results show that the colliding activation efficiency between the sorbent particles and the spray water droplets in the prefixed alkaline spray generator may reach about 70%, which is significantly higher than the 25% colliding activation efficiency in in-duct injection FGD. And SO2 removal efficiency reaches 70%, higher than that of in-duct injection FGD at the same conditions. The study confirms it is a new simple compact and highly-efficient semi-dry FGD method.

Studying molecular recognition in aqueous environments is crucial for understanding biological processes. Herein, we present a series of N-doped endo-functionalized anthracene-based cavities by introducing inward-directed pyridine units. The subtle modifications can significantly affect the binding properties of these receptors, which is similar to the mutations in biological systems. Combining theoretical calculations and molecular recognition experiments demonstrated that these “mutations” have an impact on the hydrophobicity and charge distribution of the hosts, consequently significantly influencing molecular *** is crucial for understanding the intricate mechanisms of molecular-level interactions in biological receptors.

氧化锆具有声子能量低,介电常数高和带隙较宽等优良特性,并且立方相的氧化锆(cZrO_(2))透光率高,适合作为上转换发光材料的基质.采用基于密度泛函理论(DFT)的第一性原理平面波赝势法研究了稀土元素Er、Yb和Y掺杂cZrO_(2)的电子结构和光学性质.计算结果显示,掺入Y元素后,cZrO_(2)转变为直接带隙材料,继续掺入Er和Yb原子后,费米能级移动到价带内,带隙显著减小.Y和Er混掺后,增强了cZrO_(2)在近红外波段的吸收能力.继续掺入Yb后,cZrO_(2)对近红外波段的吸收能力有了进一步地增加.
