Self-healing metals possess the capability to autonomously repair structural damage during service. While self-healing concepts remain challenging to be realized in metals and metallic systems due to the small atomic volume of the mobile atoms, the slow diffusion unless at high temperatures and the strong isotropic metallic bonds, the scientific interest has increased sharply and promising progress is obtained. This article provides a comprehensive and updated review on the developments and limitations associated with the various modes of potentially healable damage induced in metals and alloys, i.e., stressinduced damage, irradiation-induced damage in bulk materials and contact damage in corrosion protective coatings. The spontaneous intrinsic healing mechanisms not requiring external assistance other than the material operating at the right temperature and an assisted healing mechanism with external intervention are reviewed. Promising strategies to achieve self-healing in metals are identified. Finally, we give some prospects for future research directions in self-healing metals.

目的:吸力式基础具有投资费用低、施工时间短、无噪音和可重复使用等优点,因此被广泛应用在海洋工程领域。本文针对吸力式基础设计中的关键问题,主要综述现有设计理论,指出理论缺陷,并给出设计建议。创新点:综述砂土、粘土和成层土中吸力式基础的安装、回收、基础承载力、基础沉降和服役性能中的关键科学问题和现有设计理论。方法:1.基于文献报道的现场试验和模型试验,针对吸力式基础安装过程中的沉贯阻力、临界吸力和土塞效应,评估现有设计理论的准确性;2.分析粘土和砂土中吸力式基础的完全排水、完全不排水和部分排水条件下静力和循环承载力计算理论;3.针对吸力式基础的长期服役性能,分析荷载引起的基础变形、固结沉降、循环再固结沉降和极端荷载下的"棘轮效应"。结论:1.现有的吸力式基础安装中沉贯阻力计算理论没有普适性;对于临界吸力的计算,由于没有考虑"土拱效应",理论计算值均低估了安装吸力。2.对于粘土中吸力式基础承载力的计算需要考虑循环作用下土体的强度弱化和基础-土间空隙引起的承载力降低,而砂土中基础承载力计算需要考虑排水条件的影响。3.对于吸力式基础的长期服役性能,特别是基础变形的计算,目前还缺少成熟的计算理论。

Worldwide construction and demolition waste (CDW) is currently dumped. To close the building cycle and the building materials cycle by recycling CDW in high technical applications, the technical quality of stony materials must be improved. For this purpose, concrete rubbles and brick rubbles, the two major stony constituents of CDW, should be separated from each other. Based on the differences in density and content of Fe-2O-3 between the two materials, a wet method of jigging and a dry method of magnetic separation are effective,tested.

AIM To study the effect of different techniques of cystic duct closure on bile leakage after laparoscopic cholecystectomy(LC) for biliary *** A systematic search of MEDLINE, Cochrane and EMBASE was performed. rate of cystic duct leakage(CDL) was the primary outcome. risk of bias was evaluated. Odds ratios were analyzed for comparison of techniques and pooled event rates for non-comparative analyses. Pooled event rates were compared for each of included *** Out of 1491 articles, 38 studies were included. A total of 47491 patients were included, of which 38683(81.5%)underwent cystic duct closure with non-locking(metal)clips. All studies were of low-moderate methodological quality. Only two studies reported separate data on uncomplicated and complicated gallbladder disease. For overall CDL, an odds ratio of 0.4(95%CI: 0.06-2.48)was found for harmonic energy vs clip closure and an odds ratio of 0.17(95%CI: 0.03-0.93) for locking vs non-locking clips. Pooled CDL rate was around 1% for harmonic energy and metal clips, and 0% for locking clips and ligatures. CONCLUSION Based on available evidence it is not possible to either recommend or discourage any of the techniques for cystic duct closure during LC with respects to CDL,although data point out a slight preference for locking clips and ligatures vs other techniques. No separate recommendation can be made for complicated gallbladder disease.
