The metal-organic framework MO-5 has been synthesized by solvothermal method. Obtained material consists of nano-sized particle of ca. 100 nm size. The material has been physico-chemical characterized regarding structural and textural properties by XRD, FTIR, nitrogen adsorption/desorption, thermal analysis and ESA experiments. Palladium supported MOF-5 catalyst has been prepared by adsorption inclusion method. The catalyst was activated by treatment with supercritical carbon dioxide （scCO2） followed by mild reduction with hydrogen solved in scCO2. The obtained catalyst is shown to be stable and active and shape selective in hydrogenation reactions of alkenes using supercritical carbon dioxide as reaction medium. The catalytic active Pd species are located inside the pores. Positive surface charging seems to prevent deposition of active species at the crystal surface of the MOF. The catalyst is long time stable and re-useably. These findings show the potential of porous MOFs for applications under supercritical conditons and resisted repeated pressuring to 120 bar at elevated temperature.

全混凝土液化天然气(ACLNG)储罐具有广阔的发展前景.储罐受到椭圆形弹体冲击的过程是一个瞬态、强非线性、强耦合的复杂动力学问题.本文建立了小型圆顶ACLNG储罐在侵彻和爆炸载荷作用下的动态响应和损伤的流固耦合数值分析模型.通过与已有实验数据作对比,验证了自编程拉格朗日-欧拉网格映射算法和虚拟流体欧拉-拉格朗日算法(GEL)的有效性及仿真结果的准确性.探讨了不同炸药、不同起爆点位置的爆炸冲击波传播规律,对比分析了流场中不同位置压力的相对关系.此外,还研究了储罐在不同条件下的损伤特性.结果表明:(1)爆炸后冲击波将会在很短时间内衰减,导致不同位置的压力峰值差异较大;(2)当同一炸药在相同位置起爆时,侵彻形成的破孔有一定的泄压作用;(3)储罐侧壁与顶底板连接处因冲击波汇聚和应力集中更容易损伤破坏,应优先保护.

超材料是实现新奇弹性波调控功能的关键所在.其中,被动超材料最先被研究者关注,目前已实现了波动阻隔、负折射、波聚焦、绕射隐身等反常波动效果,因此被动超材料在低频减振降噪、结构健康监测和波动能量收集等方面有着广泛的应用前景.然而,被动超材料在制备完成后,其等效属性和波控功能很难再根据实际需求进行调节,限制了其在真实工作环境中的应用.近年来出现的力电耦合超材料能够实现波动性质的主动调节,突破了被动超材料的限制,因此受到越来越多的关注.力电耦合超材料在微结构材料组分和拓扑构型之外引入多物理场耦合效应来改变等效属性,并能通过外部电场控制实现特定的非常规属性或者材料属性的主动甚至自适应调节.本文首先介绍力电耦合超材料的基本概念.然后,根据外部电场作用方式的不同将力电耦合超材料分为两类;并从等效属性的电场调控机理、耦合电场/微结构设计和波控功能等方面,对力电耦合超材料的研究现状和发展趋势进行了详尽的介绍和讨论.最后,针对波动控制的功能拓展、宽低频实现机理、动态均匀化以及高效数值预报等方面,对未来力电耦合超材料的研究方向与应用领域进行展望.
