CuInSe2 thin films were obtained by selenization of the Cu-In precursors in the atmosphere of Se vapour, which were prepared on stainless steel and titanium substrates by electrodeposition. The films were characterized by XRD, scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS). The respective influences of composition, phases and surface morphology of Cu-In precursors on indium loss were investigated. The results indicate that the indium loss occurs in selenization process because of volatile In2Se arising. The indium loss is less in selenization process of Cu-In precursors contained CuIn, Cu2In and In phases.

Strength Of Adhesion

In order to research the adhesion of sputtering protective coating of Gd. Gd substrates was coated with 1Cr18Ni9Ti by means of DC magnetron sputtering technology. The characteristics of the film were investigated by scanning electron microscopy (SEM), EDS, SPM and the adhesions of film was tested by tension test. The results show that the films of 1Cr18Ni9Ti are distributed by means of islands when the sputtering was initiated and the grains are like thin fiber. After a few minutes, the films are smooth and perfect, the interferences between 1Cr18Ni9Ti and Gd join together strongly, and the largest strength of adhesion is 24.7MPa when the sputtering density is 966 w/cm2 and the sputtering time is 8 minutes.

Microbial Attachment

Milk contact surfaces were observed by scanning electron microscopy (SEM) techniques for possible microbial attachment. Cultures of Pseudomonas fragi 4973, Staphylococcus aureus JAL, Streptococcus lactis C2, Streptococcus cremoris and Lactobacillus bulgaricus RR inoculated onto glass coverslips or stainless steel chips were examined. Stainless steel surfaces displayed many possible harborages for microbial colonization. SEM examination of P. fragi 4973 showed development of fibrous material, with numerous stick-like projections extending from the cell to the glass or stainless steel surface. These apparent attachment appendages became more pronounced as contact time increased. S. aureus, S. lactis, S. cremoris and L. bulgaricus did not display such fibrous material.

An method for making AlN(aluminum nitride) nanowires by double decomposition, and the effection of additives was described. Future more, the growth mechanism of AlN nanowire synthesis with addictive were analyzed. AlN nanowire were synthesis by he AlCl3 and NaN3 in stainless steel cauldron without solvent and using Mg and Zn as additive. X-ray diffraction (XRD) and scanning electron microscopy (SEM) were used to study characters of the AlN nanowire. It is shown that the process can produce AlN nanowire with mean diameters ranging from 50 to 100 nm at 450°C. The additive has effective facilitated on the synthesis of aluminum nitride nanowires, can improve the properties of aluminum nitride nanowire, minish the average diameter of aluminum nitride nanowires.
