The model deals with variable relationships within an organization and provides a framework for overall organizational design that may include relationship among different design variables and external relationship with environment. Based on the researches of virtual organization, this paper also illustrates the new model of organization in the real world such as Beijing 2008 Olympic games and Dongfeng Automobile group.展开更多
A novel polyoxometalate-based hybrid modified by 3d-4d/2-ptz heterometallic organic chains[n-ptz= 5-（n-pyridyl）-tetrazolate], Ag2[Cu（2-ptz）2][β-MosO26]0.5-H20（1）[2-ptz=5-（2-pyridyl）-tetrazolate], was synthesi...A novel polyoxometalate-based hybrid modified by 3d-4d/2-ptz heterometallic organic chains[n-ptz= 5-（n-pyridyl）-tetrazolate], Ag2[Cu（2-ptz）2][β-MosO26]0.5-H20（1）[2-ptz=5-（2-pyridyl）-tetrazolate], was synthesized under hydrothermal conditions. The 3D framework structure of compound 1 was constructed from 1D novel 3d-4d heterometallic organic chains [CuAg2（2-ptz）2]2＋ as cationic complexes and [β-Mo8026]4- polyoxoanions via Cu--O and Ag--O bonds, in which each [fl-MosO26]4- polyoxoanion was surrounded by six such chains. The electrochemical and photocatalytic properties of compound I were investigated.展开更多

The study shows that the two SM donors possess similar absorption spectra and energy levels but different crystalline structures in solid films. The carrier transport property and phase separation morphologies of the blend films have also been fully investigated.By employing PC71 BM as the acceptor, the power conversion efficiency(PCE) of DRTB-O:PC71BM and DRTB-T:PC71BM based devices were 4.91% and 7.08%, respectively. However, by blending with IDIC, the two SM donors exhibited distinctly different photovoltaic properties in fullerene-free OSCs, and the PCE of DRTB-O:IDIC and DRTB-T:IDIC based devices were 0.15% and9.06%, respectively. These results indicate that the replacement of alkoxyl with alkylthienyl in designing SM donor materials plays an important role in the application of fullerene-free OSCs.展开更多
