In order to reduce the energy consumption of industrial clothes dryer, the problems of unreasonable structures and energy utilization insufficiency about dryer were researched. To improve the efficiency of the dyer, panel and shutter were added on the dryer entrance, the backflow zone at the bottom and the dryer expor…
Decal method as one of the membrane eletrode assembly(MEA) fabrication methods indirectly coating catalyst layer on the proton exchange membrane, its manufacturing possesses are easy, and the cycle is short, and it doesn't contact with solutions to effectively avoid the dissolving and swelling problems. Catalyst ink w…
To explore the bioleaching characteristics and process conditions of valuable metals in bioreactor which from waste printed circuit boards so as to promote the practical application of bioleaching technology,the designed batch mode bioleaching reactor and was used and strain Thiobacillus ferrooxidans Z1 was isolated,t…
Research situation, coating composition and processing method of solar-heat insulated coatings are reviewed. Influences on the efficiency of solar-heat insulated coatings on fabric are also analyzed. Then the further development of solar-heat insulated coatings is outlooked.
The synthesis of acetyl salicylic acid by using salicylic acid and acetic anhydride with using glacial acetic acid as catalyst was studied. The factors which had effects on the yield of acetyl salicylic acid were researched systematically, such as types of catalysts, ratio of raw materials, reaction temperature and ti…
The high speed hot compression experiment was carried out using Gleeble3500 thermal simulator. The rate deviates from the target rate due to the stroke model and the heat from plastic energy does not circulate out in a short time,which leads to the specimen temperature deviating from the set temperature,so the materia…
Bi2Te3 thermoelectric films were prepared by electrodeposition on stainless steel substrates, the structure and morphology of the films were characterized by XRD,SEM and AFM.Firstly,cyclic voltammogram was used to study the Bi3+,HTeO+2 and their coexistent solutions in HNO3.The electrochemistry growth of Bi2Te3 was co…
To improve the ionic conductivity and tensile intensity of poly vinylidenefluoride-hexafluoro propylene( PVDF-HFP) matrix polymer electrolyte,complex polymer electrolyte PVDF-HFP-Si O2 is prepared by phase inversion method. The morphology is characterized by scanning electron microscope( SEM),the crystal structure of…
Corrosion of steel Q235 B and ZG25 in pot-bearings is investigated by means of visual inspection,chemical analysis,microstructure analysis,XRD and SEM. The results show that the chemical composition and microstructure of the two types of steels meet the standard requirement; the rust of steel piston is composed of γ-F…
The microstructure and properties of magnesium alloy squeeze casting automobile control arm was studied by OM,SEM,EDS and XRD. The control arm squeeze casting microstructure shows that the structure is composed of α-Mg matrix and β-Mg17Al12phases which distributes along the grain boundary and eutectic structure. The t…
Two kinds of transparent scratch-resistant coating with different silica sol contents were synthesized,and their nanomechanical and nanotribological properties from the surface to bulk regions were investigated.The results show that the improvements of the mechanical properties are ascribed to the performance of nanos…
Ordered mesoporous materials with unique structure and properties have been investigated at home and abroad in recent years. In this article,the research development of ordered mesoporous materials and the preparation methods of mesoporous materials,mainly including template method and solvent evaporation induced self…
Transition metal has an important effect on the electrocatalytic activity of non-noble metal catalysts for oxygen reduction reaction(ORR).In this work,the precursor containing MWCNTs,polyaniline,Fe and Co was firstly synthesized,and then the precursor was heated at 900℃ under N2 to obtain the C-N catalysts with differ…
In the process of projectile explosive driving,the front surface of the projectile whose thickness is larger than a certain size is usually packaged to reduce the negative pressure and prevent spalling.It is found that two negative pressures may be produced in the packaged projectile under the explosive load pulse.The…
Using AAO as templates and SeO2 as Se source,reduction process of SeO2 was analyzed in alkaline electrolyte by electrochemistry method. The deposition potential and electrolyte consisting were obtained. We also investigated the deposition mechanism. Then CdSe nanowires were produced using constant potential deposition…
Because the complete reaction product of lithium and sulfur is Li2 S, the theoretic capacity of elemental sulfur cathode in a lithium sulfur battery is 1675mA·h/g, which is much higher than other cathode materials of LiFePO4, LiCoO2, et al. And sulfur has low price and non-toxic, which is an ideal cathode material. Ho…
In this paper,one-dimension ZnO arrays have been assembled on the indium tin oxide(ITO)coated glass substrates by using electrochemical deposition under different conditions.The Crystal structure of one-dimension ZnO was examined by X-ray diffractometer and its morphologies were observed with a Field emission scanning…
For the self-consistent field theory( SCFT) simulation of the phase diagrams of copolymer blends, the grand canonical ensemble and canonical ensemble need to be combined in the simulation. Through converting the variables between grand canonical ensemble and canonical ensemble,we can calculate the variables of grand c…
A kind of new high property die casting A1 alloy is developed by ingredient and Die casting process parameters optimum design on the base of ADCl2 alloy. It is seen from the result of the modified ADCl2 alloy mechanics-experiment that the as-cast mechanics property values of tensile strength( δb) 309.6 MPa,elongation(…
Tumor lysis syndrome(TLS) results from a sudden and rapid release of nuclear and cytoplasmic degradation products from malignant cells. It is a rare complication in adult patients with solid tumors who are undergoing treatment. Herein, the authors present a case with advanced hepatocellular carcinoma(HCC) who develope…
