The EMAC atmospheric chemistry – general circulation model was used, with circulation dynamics nudged towards ECMWF ERA-Interim reanalysis data. We applied a resolution of approximately 0.5 degrees in latitude and longitude. The model accounts for emissions and transport of the radioactive isotopes 131I and 137Cs, and…
In this paper we report about the peculiarities of thermodynamic functions of quantum electron gas in layered crystals. In such materials the conductivity along the layers exceeds by several orders the conductivity across layers. To these structures depend layered materials: YTe3, LaTe3, CeTe3, InSe, which are conside…
合成了一个多功能的配体1H-3-（3-吡啶）-5-（3′-吡啶）-1,2,4-三唑（3,3′-Hbpt,1）并得到了配体的晶体结构,运用DFT理论计算了配体的最优构型、优势构象和电荷分布。在此基础上,水热合成了一个配位化合物：[Co（3,3′-Hbpt）2（H2O）4]·（ad）·6H2O（2）（ad=己二酸）,结构分析表明配合物2是零维单核化合物,它的三维超分子结构是由分子间氢键连接而成,其中包含着由游离的己二酸分子填充的矩形孔道。值得注意的是,配体在配合物中的几何结构和构象与理论计算的结果一致。另外,利用热重分析研究了配合物2的热稳定性。

This thesis presents improvements to a method for measuring the production of biogenic silica (bSiO2) by diatoms, a group of microscopic algae with siliceous cell walls (frustules) that dominate the marine cycling of silicon (Si) and account for a significant proportion of global marine primary productivity. Using the…
This PhD research was first illustrated that the use of amorphous PHB contained in whole cells of the bacterium Alcaligenes eutrophus in lyophilized and freshly grown cell forms induced similar and even better beneficial effects on the growth performance or disease resistance of Artemia nauplii or M. rosenbergii larva…

Zellpenetrierende Peptide (CPP) werden in den letzten Jahren zunehmend als ein \nvielversprechender Ansatz für den erfolgreichen Transport bioaktiver Moleküle für \ntherapeutische oder diagnostische Zwecke in die Zelle diskutiert. Gegenüber anderen \nmolekularen Transportern weisen sie eine geringe Toxizität und Immun…
The purpose of this study is to experimentally analyse the performance and the exhaust emissions of a diesel engine operating on nanodiesel blended fuels. Multi wall carbon nano tubes (CNT) (40, 80 and 120 ppm) and nano silver particles (40, 80 and 120 ppm) with nano-structure were produced and added as additive to th…
This is a 3d phantom generated by actual CT images. It's size is 128*128*12. That is, there are 12 slices of image in this dataset with the resolution of each slice is 128*128. The datatype in this file is unsigned char.
Sonoluminescence is a complex phenomenon, the mechanism of which remains unclear. The present study reveals that an abnormal ionization process is likely to be present in the sonoluminescing bubble. To fit the experimental data of previous studies, we assume that the ionization energies of the molecules and atoms in t…
A novel urchin-like Zn/ZnO/TiO2 hierarchical structure directly growing on fluorine-doped tin oxide (FTO) glass is prepared by a simple sintering process, and the dye-sensitised solar cells (DSSCs) based on such a structure present desirable photoelectrochemical (PEC) properties. The research confirms that the DSSCs b…
