Fuel cell is one of the most promising power sources towards high-efficiency, low-emission and environmental benign application. In pursuit of a higher performance, electrocatalyst is a crucial research focus. Compared with commercial carbon support, TiO2exhibits the advantages of higher stability, higher porosity and stronger metal-support interaction. In this article, we give a brief overlook on the influence of diverse crystal and morphology structures on their eletrocatalytic property in fuel cells. Besides, to better meet the demand of practical electrocatalysts, three different methods are summarized to overcome its relatively poor electrical conductivity. Overall, TiO2is a promising support material of electrocatalysts in fuel cells.

Direct ethanol fuel cells are considered a promising power source for future portable electronic and automotive applications. This article reviewed the synthetic methods commonly used to prepare Pd-based catalysts for the ethanol electrooxidation in alkaline media. The progress in the mechanism studies of ethanol oxidation reaction (EOR) on Pd electrode in alkaline medium by cyclic voltammetry and electrochemical in situ FTIR spectroscopy was also reviewed. The recent studies revealed that the EOR is fairly complicated, and it is difficult in CC bond cleavage for the complete oxidation of ethanol to CO2, and ethanol is selectively oxidized to acetate on Pd-based catalysts in alkaline media. Overall, what is most important is to explore new Pd-based alloy catalysts with high ability to break the CC bond to promote complete oxidation of ethanol as well as increase the efficiency of DEFCs.

Purpose: To explore the anti-proliferation effect of the Shenfouweikang in treatment of chronic atrophy gastrititis. Methods: Wistar rat was used as the experimental model. The rats were divided into three groups, one control and the two drug administration experimental groups. Animals in the two experimental groups received either Shenfouweikang or Dele granule over a 90-day period starting at the first day after drug administration. Animals received saline as controls. All the rats were sacrificed at 91 days after treatment. The anti-proliferation effect was assessed by two ways: (1) The weight was periodically measured during the life of the animals. (2) The morphological changes of gastric mucous were examined by pathology analysis. (3) The expression of heat shock protein 70 was detected by immunohistochemistry. Results: Compared with controls and Dele granular powder, the dysplasia in rat chronic atrophy gastrititis model was significantly inhibited and reversed in the Shenfouweikang decoction group. The expression of heat shock protein 70 was decreased after Shenfouweikang herbs treatment. Conclusion: Shenfouweikang herbs could produce anti-proliferation effect through reversing the dysplasia of chronic atrophy gastrititis through down-regulating the expression of heat shock protein 70.

Heat shock protein 72 (HSP72) and glycoprotein 96 (gp96) are highly expressed in cancer tissues. Recent studies indicate the possible roles of HSP72 and gp96 in the development and progression of gastrointestinal carcinomas but detailed information is still ambiguous. The aim of the study is to investigate the correlation between clinicopathology and expression of HSP72 and gp96 in human common gastroenterological cancers- esophageal squamous cell carcinoma, gastric adenocarcinoma, colonic adenocarcinoma and hepatocellular carcinoma. The results showed that HSP72 and gp96 were highly expressed in gastroenterological carcinomas. HSP72 and gp96 were mainly stained in cytoplasm. HSP72 and gp96 expression were significantly associated with the presence of tumor infiltration, lymph node and remote metastasis. The results indicate that there exists a significant correlation between the expression of HSP72 and gp96 and the progression of gastroenterological carcinomas.

In this work, a laminated microstructure-plate electrically heated micro evaporator was proposed. The effects of microstructure types on the evaporation efficiency of electrically heated micro evaporator under different input voltage values and flow rates of water were investigated. It was indicated that the triangular microstructure plate presented the best evaporation efficiency regardless of the change of input voltage and feed flow rate. The nonuniform-distributed microchannel plate presented better evaporation performance than that of uniform-distributed microchannel plate, while the triangular microstructure plate presented higher evaporative performance than that of rectangular microstructure plate.

A new approach of spontaneous deposition was carried out to prepare the Ru/Pt film electrocatalyst for direct methanol fuel cells. This deposition method just made Pt like a ‘skin’ covered Ru films, which reduced the load of Pt but obtained a higher activity. The Pt-modified Ru films electrode was studied with the cyclic voltammetries and in-situ ATR-SEITA spectra on methanol oxidation. Compare to bare Ru and Pt, the bands of the adsorbed CO and water observed in IR spectra can be assigned. The present results give a clue for designing new electrocatalysts for DMFCs.

Heat shock protein 72 (HSP72) and glycoprotein 96 (gp96) are highly expressed in cancer tissues. Recent studies indicate the possible roles of HSP72 and gp96 in the development and progression of lung carcinomas but detailed information is still ambiguous. The aim of the study is to investigate the correlation between clinicopathology and immunolocalization of HSP72 and gp96 in human lung carcinoma. Immunohistochemistry demonstrated that HSP72 and gp96 expression in lung carcinomas with metastasis was significantly higher than those with non-metastasis. HSP72 and gp96 expression were significantly associated with the presence of tumor infiltration, lymph node and remote metastasis.

On the basis of analyzing the properties of the Camellia oleifera peel and seed, for the purpose of solving the problem of the separation of peel and seed, a device has been designed based on the aerodynamic principles. The single factor experiment has been carried out to research how the feeding angle, feeding height, fan inclination and fan height can influence the seperation. The result shows that the feeding angle has a significantly effect on the separation, the suitable angle is 40°; the feeding height has a significantly effect on the separation; when the feeding height is 200mm, the peel in the seed zone is the least, but the seed in mixing zone is the most, when the feeding height is 300mm, the seed in the mixing zone is the lesat, but the peel in the seed zone is the most, so in the actual production, the feeding height need to be comprehensive considered; the fan inclination has a significantly effect on the separation, the suitable inclination is 15°; the fan height does not have a significant effect on the separation.

The Ru/C nanocomposites with loading of 20wt% were prepared by ethylene glycol in the presence of XC-72. Carbon-supported Ru nanoparticles were decorated with Pt by spontaneous deposition method after Ru surface oxides were reduced in the hydrogen atmosphere at 180 for 2h. TEM indicated that the average particle size of catalyst was about 4nm with excellent dispersion and the XRD analyzing results showed that Pt had decorated on surface of Ru. The anti-poisoning ability was studied by pre-adsorbing CO striping voltammetric curves in 0.1M HClO4. Catalytic activities of the prepared Pt/Ru/C were studied by cyclic voltammetry in a solution of 0.5 mol/L CH3OH + 0.1 mol/L HClO4. The results showed that the oxidation current density was far more than 60wt% RuPt/C (E-TEK) and 20wt% Pt/C (Johnson Matthey). At the same time, the study also showed that the prepared catalyst not only had a higher catalytic activity to methanol, but also had lower Pt loading.
