  In this talk,we describe a systematic way of computing a globallyadapted Tucker-type basis for solving the Kohn-Sham DFT eigenvalue problem,by using a separable approximation of the Kohn-Sham Hamiltonian.The rank of the Tucker representation and the computational complexity of the resulting self-consistent DFT calculations using these Tucker basis are examined on representative benchmark examples involving metallic and insulating systems.

纳米多孔材料因其低密度、大比表面积、量子限域效应等优异的物理化学性能,在催化、药物传输、能量存储与转换等方面受到了广泛的关注。在具体合成过程中,如何获得晶化纳米孔材料是具有挑战性的工作。通常情况下,在晶化的过程中,纳米孔会遇到压缩或者塌陷等问题,导致比表面积降低,孔道堵塞,作为催化材料活性降低。有基于此,我们开发了多种合成晶化纳米孔材料的方法,获得了几个系列的高性能光催化产氢晶化纳米孔氧化物材料。
采用以H2O2为氧化剂,罗丹明B废水催化氧化降解反应为模型反应,以声变幅杆浸入超声波增强Fe/MCM-41分子筛催化剂的催化降解性能。结果表明在常温下,超声功率为450W条件下,超声增强催化剂催化降解废水仅需30min就可实现废水的去除率达90%,而同样的去除率需传统的75 ℃下反应120min,可大大缩短反应时间,降低能耗,如图1所示。进一步对比传统加热和超声波增强体系下催化降解后废水TOC去除
采用水热晶化法合成了ZSM-5/11共晶分子筛,并采用XRD,SEM,N2-物理吸附,NH3-TPD等表征手段对ZSM-5/11共晶分子筛的酸性、孔道结构进行了表征.结果表明,合成的ZSM-5/11共晶分子筛具有较好的结晶度和酸性,与普通ZSM-5相比更大的比表面积和孔体积.合成的ZSM-5/11共晶分子筛在苯、甲醇烷基化反应中,苯的转化率40.19%,甲苯和二甲苯总的选择性达到了87.75%,与
我们的研究结果表明,通过在MIL-101(Cr)的多孔结构中负载聚乙烯亚胺(PEI)下可以显著提高其在低压下二氧化碳的吸附性能.研究发现,不同分子量的PEI对最后负载后产物具有较大的影响.低分子量的PEI可以较为容易的扩散进入到MIL-101(Cr)的孔中,随着分子量的增加,扩散的难度增加.在0.15 bar 和 25℃下,A-PEI-300具有很高的CO2吸附量(3.6 mmol g-1)和超高
Given a matrix subspace,there are relevant reasons to ask for a basis of lowest rank.A greedy algorithm will provably find it,but the subproblems are NP-hard.

稀土配合物由于其有趣的结构和在磁性、催化和荧光探针等方面的潜在应用而被人们广泛关注[1-4]。本文采用水热法合成了两种稀土配合物[Tb(3-SBA)(IP)OH(H2O)]·H2O(1)、[Pr2(3-SBA)2(IP)2(NO3)2(H2O)2]·H2O(2)(3-SBA=3-羧基苯磺酸,IP=咪唑[4,5-f][1,10]-邻菲啰啉),并用X-ray单晶衍射仪测定了它们的晶体结构。配合物1是以
