In the study, the system was heated up without electric device, i.e., the fuel providing the required thermal energy through an integrated BOP (balance of plant). The ex-situ experiments, without an SOFC stack installed in the system, were first conducted to investigate the operability of a BOP apparatus. It was found that the BOP possessed high conversion rates for both steam reforming and water gas shift reactions. The total fuel concentration of hydrogen and carbon monoxide from the reformer was around 91.2%. The system validation tests showed that, with the natural gas as fuel, the output power from the stack reached to 1,060 W, while the fuel utilization efficiency and electrical efficiency were 67.16% and 45.0%, respectively. A steady 600-hour system operation test was carried out at an average system temperature of 694 C. Of which, a 36-cell stack was employed for the test.

The method is based on MAE (microwave-assisted extraction) of herbicides using ethyl acetate as extractant. The economy in the use of solvents coupled with the decrease in extraction time and lower power consumption make MAE a technique that meets the principles of green chemistry. MAE operational parameters, extraction time, mass of the sample and extraction temperature, were optimized by RSM (response surface methodology). Determination of analytes was completed using gas chromatograph coupled to mass spectrometry detection. The selected triazines could be efficiently extracted by the solvent at 80 °C for 10 min, with 80% output of maximum power. When the optimized method was applied to analysis samples, the recoveries of analytes ranged from 81.8 to 106.0% and relative standard deviations were lower than 8.41%. The method is stable and reasonable, which can be used for the determination of ninetriazine herbicides residues in soil.","PeriodicalId":67212,"journal":{"name":"化学与化工:英文版","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2017-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43486400","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The best entrapment obtained was 83% with a loading capacity of 2.9% (Batch D) and was used in comparison with the unformulated drug to check for the in vivo efficacy. The results show higher efficacy with the formulated drug than with the pure drug both in vitro and in vivo.

The final microstructure determines the required mechanical properties such as high formability, high toughness and adequate strength. For this reason it is relevant to identify and determine the volume fraction of the ferrite, bainite and martensite present in the structure. The microalloying elements: V, Nb and Ti promote carbides precipitation during cooling. The precipitates control the grain size refinement during hot rolling process and the mechanical properties of the steel. In this sense it is necessary to increase the knowledge on the microstructure evolution at different cooling rates. In this paper, the results obtained on two low carbon microalloyed steels (with C contents between 0.11%-0.06%) are reported. An integrated methodology including dilatometry in combination with microscopy techniques was applied. By EBSD (Electron Backscatter Diffraction) technique and microhardness measurements, the structural study was completed. Through a thermodynamic simulation using Fact Sage the type of precipitates in the studied steels structure at the temperature range between 950 °C and 450 °C, were predicted. The information on the evolution of the steel structure at rolling process conditions is relevant to consider changes in processing conditions.","PeriodicalId":67212,"journal":{"name":"化学与化工:英文版","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2017-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47658245","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The adsorption is physical and the process is endothermic, and Freundlich isotherm fits the data better than the Langmuir isotherm. The adsorption can be generally described by electrostatic interaction (Coulomb’s force) between the adsorbent and the adsorbate.

The size of the particles after crystallization of the precipitated former conjugate was controlled with XRD (X-ray diffraction). It is found that the conjugate self-assembling produces the smallest grains with the diameter of 65 ± 7.5 nm measured at contact with the support. This particle size matches the crystallite size of 44.2 nm found by XRD for the conjugate taking into account the particles deformation under the contact with the support. The self-assembly of the smallest particles in solution has produced non-transparent for light core observed on mica with the size varied between 300 to 400 nm.
