甲酸是一种安全方便的氢气能源材料，其在化学合成和可持续的能源储存方面具有极大的应用前景，但是合成一种在室温下就可以可控的和有效的催化分解甲酸制氢的催化剂具有非常大的挑战。我们通过一步快速的合成方法制备了一种新型的AgPd@MIL-100(Fe)核-壳纳米颗粒，而且第一次把它应用于室温下、不加任何添加剂的条件下催化分解甲酸制氢反应。非常有意义的是，在所有制备的催化剂中，具有7 nm壳层厚度的AgPd
晶态微孔化合物(如磷酸盐、亚磷酸盐、草酸盐等)通常是在水热、溶剂热或离子热条件下合成出来。为消除溶剂对产物结构的影响,我们开发出无溶剂合成法,制备得到系列具有新型开放骨架结构的亚磷酸盐、磷酸盐、草酸盐、硫酸-草酸盐、磷酸-草酸盐和亚磷酸-草酸盐。我们系统考察了具有不同价态和配位环境的金属离子(如Mn2+,Fe2+,Co2+,Ni2+,Zn2+,Mg2+,Al3+,Ga3+,In3+,Sn2+,Sb
利用反扩散技术将共生性良好的 ZIF-8(一种金属有机骨架， MOF)纳米晶体生长在三维石墨烯上[1].ZIF-8 晶体的引入极大地提高了石墨烯复合材料的比表面积.碳化后的石墨烯-ZIF 复合材料具有分级的多孔结构，表现出较高的电容性能和良好的稳定性.由于具有不同孔的大小和分布的 MOFs 材料的多样性[2]，我们期待此工作将为石墨烯与金属有机骨架复合材料在电容器之外的能量存储设备的应用打开通路.

We propose a method to quantify uncertainty for physical systems with high dimensional stochastic space using generalize polynomial chaos expansion.
Many inference problems include PDE-based forward models,but discretization error is an important source of statistical bias.We successfully address this problem by constructing a probability measure
We study how to parametrize the effect of the Y variables Y on the X variables of a dynamical system,when the X-Y coupling is weak.Using the Ruelle response theory,one can construct a surrogate dynami
