摘要：Designing and fabricating highly efficient photocatalysts for water splitting is a promising strategy to address energy and environmental *** sulfide(CdS)has received significant interest as a photocatalyst for visible‐light‐induced hydrogen(H2)***,the severe photocorrosion,high overpotential,rapid charge recombination,and sluggish surface reaction kinetics drastically hinder its practical application in water ***,uniform zinc cadmium sulfide(Zn_(0.5)Cd_(0.5)S)nanoparticles were anchored on ultrathin Ni(OH)_(2)nanosheets via a facile solution‐phase approach to form an intimate two‐dimensional(2D)/zero‐dimensional(0D)*** visible light irradiation,the 7%Ni(OH)_(2)/Zn_(0.5)Cd_(0.5)S composite exhibited the highest H2 production rate of 6.87 mmol·h^(–1)·g^(–1)with an apparent quantum yield of 16.8%at 420 nm,which is almost 43 times higher than that of pristine Zn_(0.5)Cd_(0.5)S and considerably higher than that of the Pt/Zn_(0.5)Cd_(0.5)S *** high photoactivity of the 2D/0D Ni(OH)_(2)/Zn_(0.5)Cd_(0.5)S heterojunction can be ascribed to its unique and robust structure,wherein the ultrathin Ni(OH)_(2)nanosheets not only provide an excellent platform for the incorporation of Zn_(0.5)Cd_(0.5)S nanoparticles but also serve as an effective cocatalyst to promote photoinduced electron transfer and offer more active sites for photocatalytic H_(2) *** work paves the way toward the development of versatile,low‐cost,and highly efficient 2D/0D heterojunction photocatalysts for solar energy conversion.

摘要：石材料在中国古典园林中是非常重要的造园要素。叠山置石也是造园中非常重要的手法,在中国传统造园艺术中占有非常重要的地位。景观设计与建造需要寻找自然造景石材,现在国内景观与造园需求大增,需要更多的不同种类的景石,日本与欧美国家已经研发与创新新型造园材料替代品,不但节省造园的时间,还减少对资源的破坏。中国造园风格将会成为未来造园的一个方向,研究中国造园精髓,研发配套新型造景石材是应市场需求,设计并制造符合中国文化与审美的造景材料是本次创新应用的目的。文章将基于对欧美和日本研发的新型材料进行调查所得来的数据资料进行分析,针对铸石生产和应用产生的问题进行研究探讨,并讨论如何把新型材料和传统造景相结合。

摘要：对于某大型海工栈桥的实船试验,由于传统的休息臂布置方案存在材料及施工费用高、占地面积大、布设紧张、短期使用后拆除导致浪费等缺点。为此,本文充分利用搭载平台的原有上层建筑结构,为实船试验栈桥设计了一种简易的休息臂布置方案,并进行了总体布局、强度评估,评估结果安全可靠。该布置方案最终通过实际工程验证可行,其设计思路可推广至同类栈桥/吊机等的存放方案制定。
