AbstractPhysical vapor deposited (PVD) coatings are widely-used in tool and component applications, where the predominant aims are the enhancement of the lifetime and an improvement of the economic efficiency. The achievement of these aims amongst others strongly depends on a homogeneous distribution of the coating properties with respect to the entire functional surface, in particular on complex-shaped tools. In order to obtain a sufficient coating homogeneity, pulsed high power plasma processes such as the high power pulsed magnetron sputtering (HPPMS) or the pulsed cathodic arc evaporation (PCAE) has to be chosen. In order to characterize the influence of both technologies on the coating homogeneity, the Debye sheath thickness sDat the substrate side was determined, which is expected to strongly correlate with the coating homogeneity on complex surfaces, since it is a measure for the shielding of charged coating atoms. Measurements with varying pulse parameters were performed. In addition, as reference a direct current magnetron sputtering (dcMS) and cathodic arc evaporation (CAE) process were conducted, respectively. As it is widely used as protective coating for tools in many applications, the coating system (Cr,Al)N was chosen. In the first step, the Debye sheath thickness was determined by means of Langmuir probe. A Debye sheath thickness from sD=430μm to sD=48μm was found for the different processes and parameters. In the second step, the (Cr,Al)N coatings were deposited with selected process parameters on structured tungsten carbide substrates. The coating morphology, coating thickne

8月28日，由湖北兴欣科技股份有限公司、武汉理工大学、浙江大学和湖北省标准化与质量研究院等7家单位共同起草的湖北省地方标准《多重增强钢塑复合压力管》顺利通过专家评审。据悉，该标准填补了我国大口径钢塑复合压力管行业空白，将使我国城市地下管网建设落后，渍水严重局面彻底改观。 目前，我国城市的市政水利工程大多使用球墨铸铁管、钢管、钢筋混凝土管、聚乙烯管等传统管材，这几种管材抗内压低，管体笨重，口径小，易腐蚀，易污染水质，环保性能差，不能承受高压力，而且每年仅腐蚀等原因造成的泄漏量就超过20%，并容易造成水的二次污染，是我国城市每到夏季汛期就排水不畅、渍水严重的主要原因之一。 “十三五”期间，我国将大力发展塑料管道行业，加大绿色环保、节约能源的塑料管道产品推广与应用。2014年，国务院发出《关于加强城市地下管线建设管理的指导意见》，明确提出，力争用5年时间，完成城市地下老旧管网改造，用10年左右时间，建成较为完善的城市地下管线体系，并提出在36个大中城市开展地下管廊试点工程。2015年4月，国务院发布《水污染防治行动计划》，再次要求全面加强配套管网建设，加快实施雨污分流改造，对使用年限超过50年和管质落后的供水管网进行更新改造（2020年前更新改造9.23万公里，新建管网18.53万公里）。到2017年，全国公共供水管网漏损率控制在12%以内，到2020年，漏损率控制在10%以内。 多重增强钢塑复合压力管是以高密度聚乙烯塑料与碳素结构钢冷轧钢带及优质碳素结构钢钢网为原料，通过连续挤出方式加工成复合带材后，再经过缠绕、塑料焊接加工而成的一种缠绕管道，主要用于城镇水源、海水淡化、市政给水、排水及水利工程。该管材兼具PE管防腐蚀性能好，可减少因腐蚀导致的渗透及二次水污染，并且由于加入了高强度的钢丝和钢带，极大增强了原有管材的环钢度，能获得更高的耐压等级，更难能可贵的是该管材口径可高达2600mm，实现了我国管道行业口径质的飞跃，是目前国内口径最大的钢塑复合压力管。 该管材的成功研制不仅解决了我国目前只有小口径管材的难题，也提高了管材的耐高温、承压、耐压能力。因其良好的高强度、低线性膨胀系数和抗蠕变性、耐腐蚀性能以及优异的水力特性及抗冲击性，产品一经面世，便受到管道行业的称赞和市场的青睐。 专家组一致认为，该标准符合国家相关法规规范和产业发展政策要求，结合湖北省实际情况，提出了多重增强钢塑复合压力管标准，对市政工程、水利工程、海水淡化工程等建设的发展与规范具有重要的指导作用，尤其在改变我国城市管廊建设落后、城市道路遇大雨即渍水的窘迫现状方面，将发挥巨大作用。同时，专家组并建议在地标工程应用基础上，将该标准进一步提升为行标和国标。 评审专家组由来自湖北大学、湖北省建材协会、中信建筑设计研究总院、中南建筑设计院、湖北省水利水电科学研究院、武汉市给排水工程设计院和湖北工业大学的7位专家教授组成。 编辑：徐冰冰

When simple beta-amino esters were treated with cyanate ion, dihydrouracils were formed. However, the presence of the alpha-carboxylate group in aspartic ester substrates hinders the formation of the pyrimidine ring. Instead, treatment of aspartic esters with carbonate bases yields N-substituted beta-Flactam-4-carboxylates in excellent yields, representing a green, convenient, and efficient synthesis of these biologically interesting molecules.

Power system restoration following large blackouts critically relies on the activation of black start units and/or the availability of restoration paths from alive neighbouring networks. Moreover, operating constraints on voltage and frequency are more difficult to meet than in normal conditions, due to the weakness of the grid and the lack of control resources. The speed and reliability of the process depend on the resources that are involved, the number of manoeuvres needed, and the performances of the control systems. Redundancy of solutions and resources enhances the probability of an efficient restoration. The present paper intends to illustrate the potential benefits of a VSC-HVDC system in the restoration of the Sardinian power system in a 2020 scenario. The power system of Sardinia island is a relatively small one, connected to the continental European system via two HVDC links, one of which has a third terminal in Corsica island. Connection to Corsica is also assured by an AC line. In particular, the paper envisages the upgrade of the existing SACOI (Sardinia-Corsica-Italy) HVDC link by adopting VSC technology, and it compares a conventional restoration scenario of Sardinia against scenarios where the VSC-based SACOI supports the restoration process, acting either as a black start unit or as a reactive power support device (STATCOM). The VSC allows to achieve advantages such as greater flexibility in the restoration process and stable control of the operating quantities. The work herein reported has been carried out in the context of Demo 3 of the Best Paths EU research project.
