The effect of annealing temperature on the formation of the PtSi phase. distribution of silicides and the surface morphologies of silicides films is investigated by XPS. AFM. It is shown that the phase sequences of the films change from Pt-Pt2Si-PtSi-Si to Pt+Pt2Si+PtSi-PtSi-Si or Pt+Pt2Si+PtSi-PtSi-st with an increase of annealing temperature and the reason for the formation of mixed layers is discussed.

Little has been learnt in the last 30 years about detection of HBV genome as well as its mutation analysis between hepatitis B fathers （HBF） and their children. In this study, we used nest polymerase chain reaction （PCR）, fluorescence in situ hybridization （FISH）, and DNA sequencing analysis, to examine the integrated HBV genome in paraffin-embedded testis tissues, which were taken as samples from HBE and in peripheral blood mononuclear cells （PBMC） from 74 cases of HBFs and their children who were born after their fathers＇ HBV infection （caHBF）. We found that HBV DNA existed in testis tissues, mainly in the basilar parts of the seminiferous tubules, and also in PBMC of HBE It was also documented that there were point mutations of poly-loci, insertions and deletions of nucleotides in integrated HBV genomes, and the types of gene mutations in the HBFs were similar to those in caHBE This study addresses the major types of gene mutations in integrated HBV genome in human patients and also presents reliable evidence of possible genetic transmission of hepatitis B.

This article adopts the double decomposition method, select the appropriate experimental conditions and operation process, respectively add appropriate amount of sodium carboxymethyl cellulose （CMC） as crystal control agent to study the influence of crystalline of ultrafine calcium carbonate. The experimental results show that the different concentrations of CMC as crystal control agent on the morphology and crystal structure of calcium carbonate have obvious effect, which emerge morphology change from square to spherical, crystalline transition from calcite to aragonite. Thus, the results provide experimental data and theoretical basis for the use of different additives, and provide experimental basis and feasible solution for this kind of reaction.
