Geometry and electronic structures of gallium phthalocyanine dimer and fullerene molecules were investigated by theoretical calculation. The highest occupied molecular orbital was localized on the donor site, and the lowest unoccupied molecular orbital were localized on accepter site. The present results indicate that high conversion efficiency would be expected when phthalocyanine dimers were used as solar cell materials.

Photovoltaic and optical properties of fullerene/phthalocyanine heterojunction solar cells with normal and inverted structures were fabricated and investigated. Aluminum and gallium phthalocyanines were used for the n-type semiconductor. The solar cells with inverted structure had more stability compared to that with normal structure in the air. Nanostructures of the solar cells were investigated by transmission electron microscopy, and energy levels of the molecules were calculated and discussed.

[6,6]-phenyl C61-butyric acid methyl ester: poly (3-hexylthiophene) bulk heterojunction solar cells doped with germanium phthalocyanine or germanium naphthalocyanine were fabricated and characterized. Photovoltaic properties of the solar cells with inverted structures were investigated by optical absorption, current density-voltage characteristic and incident photon to current conversion efficiency. These germanium phthalocyanine and germanium naphthalocyanine blended as the third component absorbed light with wavelength longer than 700 nm. Morphology of solar cells was investigated by atomic force microscopy, and energy levels of the solar cells were discussed for power conversion efficiency.

The two-layer cold storage method (TLM) was f irst reported in 1988, consisting of a perfluorochemical (PFC) and initially Euro-Collins' solution, which was later replaced by University of Wisconsin solution (UW). PFC is a biologically inert liquid and acts as an oxygen-supplying agent. A pancreas preserved using the TLM is oxygenated through the PFC and substrates are supplied by the UW solution. This allows the pancreas preserved using the TLM to generate adenosine triphosphate during storage, prolonging the preservation time. In a canine model, the TLM was shown to repair and resuscitate warm ischemically damaged pancreata during preservation, improve pancreas graft survival after transplantation, and also improve the islet yield after isolation. Clinical trials using the TLM in pancreas preservation before whole-pancreas transplantation and islet isolation have shown promising outcomes. We describe the role of the TLM in pancreas and islet transplantation.

Dynamic centrifuge model test was conducted to study the earthquake-induced differential settlement of foundation on cohesive ground, and the influence of asymmetry of building was investigated. During the experiment, the overconsolidated kaolin clay ground with a three-dimensional asymmetrical structure model was shaken by a basically balanced input motion, and bender elements were used to measure shear wave velocities of model ground to reveal the soil fabric evolution during and after shaking. The test results show that, the total seismic settlement of foundation is composed of instantaneous and long-term post-earthquake settlements, and most of the differential settlement occurs immediately after the earthquake while the post-earthquake settlement is relatively uniform despite its large amplitude. The asymmetry of building affects the settlement behavior considerably. Compared with 1-or 2-dimensional structures, more evident differential settlement occurs under threedimensional asymmetrical building during shaking, which accounts for one-half of the total seismic settlements and results in complex spatial tilting effects of foundation.
