In this paper we present the MEMPHIS middleware framework for the integration of CAD geometries and assemblies with derived Virtual Reality (VR) models and its specific meta data and attributes. The goal of this work is to connect real time VR applications, especially for the Design Review, with enterprise software storing and managing CAD models (Product Data Man- agement—PDM). The preparation of VR models requires expert knowledge, is time consuming, and includes selection of required CAD data, tessellation, healing of unwanted gaps, applying materials and textures, and special surface and light effects. During the Design Review process, decisions are made concerning the choice of materials and surface forms. While materials can be switched directly on the VR model, the modification of part geometries must be made on the CAD model. Our system synchronizes modi- fications of the original CAD geometries and of attributes that are relevant for the realistic rendering using the PLM Services standard. Thus, repeated work for the VR preparation can be avoided.

Titanium dioxide-double-walled carbon nano- tubes （TiO2-DWCNTs） with DWCNTs/TiO2 of 20 wt.% is prepared by a conventional sol-gel method. Doping the TiO2-DWCNTs in TiO2 photoanode, a flexible dye- sensitized solar cell （DSSC） is fabricated. The sample is characterized by scanning electron microscopy, X-ray diffraction （XRD）, Fourier transform infrared spectroscopy （FTIR） absorption, ultraviolet-visible spectroscopy （UV- vis） absorption spectra , electrochemical impedance spec- troscopy （EIS） technique and photovoltaic measurement. It is found that adding a certain amount of TiO2-DWCNTs can efficiently decrease the resistance of charge transport, improve dye adsorption. Under an optimal condition, a flexible DSSC contained with 0.50 wt.% TiOz-DWCNTs achieves a light-to-electric energy conversion efficiency of 3.89% under a simulate solar light irradiation of 100 mW. cm^2.

通过等离子体辅助分子束外延(PA-MBE),在双抛蓝宝石衬底上生长出两英寸的高质量β-Ga_(2)O_(3)单晶薄膜。利用光刻技术和电子束蒸镀金叉指电极,在薄膜上成功地制备了金属-半导体-金属结构(M-S-M)型日盲光电探测器。结果表明:日盲光电探测器的暗电流低至130 pA(20 V),对紫外波段的光响应度达到229 mA∙W^(-1);此外,器件对光信号表现出超快的瞬态特性,衰减时间为1.31 ms,器件的优异性能可归因于β-Ga_(2)O_(3)的高结晶质量和肖特基结的巨大场迁移率。该研究为未来基于更大规模的β-Ga203异质外延薄膜的深紫外(DUV)光电探测器的应用迈出了重要一步。

We report observation of dispersion for coupled exciton-polariton in a plate microcavity combining with ZnO/MgZnO multi-quantum well (QW) at room temperature. Benefited from the large exciton binding energy and giant oscillator strength, the room-temperature Rabi splitting energy can be enhanced to be as large as 60 meV. The results of excitonic polariton dispersion can be well described using the coupling wave model. It is demonstrated that mode modification between polariton branches allowing, just by controlling the pumping location, to tune the photonic fraction in the different detuning can be investigated comprehensively. Our results present a direct observation of the exciton-polariton dispersions based on two-dimensional oxide semiconductor quantum wells, thus provide a feasible road for coupling of exciton with photon and pave the way for realizing novel polariton-type optoelectronic devices.
