Structural state of adularia from Hishikari, Japan

Adularia sample was collected from epithermal Au-, Ag-bearing quartz-adularia veins from Hishikari, Japan. This adularia is rich in K, Or=94.63, clear, transparent, fine-grained and closely associated with quartz. In this study, it was determined by XRD, IR and²⁹Si,²⁷Al MAS NMR methods. The adularia studied is of high sanidine with triclinic domains in it. The occupancy of Al 2t₁=0.60, IR ordering θ=0.15.²⁹Si NMR spectrum of this adularia shows a broad triplet peak, i.e. 3 poorly separated peaks at −94.9, −96.7, −99.9. This kind²⁹Si NMR spectrum for natural high sanidine has never been reported before. And the²⁷Al NMR spectrum gives an asymmetry peak with chemical shift at 58.7 extending slightly to the low frequency. Under a violent boiling environment, Hishikari adularia rapidly crystallized from a supersaturated solution.     

西北地区湖相浊流沉积

通过对各地质时代不同野外及钻井剖面岩相特征的详细研究,认为西北地区的湖相浊流沉积均形成于湖底扇环境,浊积岩具粒序层理、包卷层理、槽模、沟模、锥模、刷模和重荷模以及滑塌褶皱等构造。划分出杂乱砾岩（A1）、具碟状构造的块状砂岩（B1）、块状砂岩（B2）、近基浊积岩（C）、无基浊积岩（D）、不规则互层的砂泥岩（E）、滑塌褶皱层（F）及页岩、硅质岩（G）等岩相。同时,归纳出内扇、中扇及外扇相结合,论述了湖泊相浊流沉积的成因及石油地质意义。     

丙烯直接环氧化Au/TiO2催化剂助剂对催化性能的影响

采用沉积沉淀法制备了一系列的Au／TiO2催化剂,分别考察了碱金属氯化物以及贵金属等助剂对Au／TiO2催化丙烯环氧化性能的影响。结果表明：催化剂中加入NaCl后其环氧化催化性能明显提高,含量为1．5％时环氧丙烷(PO)得率最高;而加入CsCl和贵金属Pt则有利于提高丙烯环氧化过程中氢气的利用效率,抑制了副产物水生成。     

西天山阿希金矿浊沸石化与古地热成矿流体系统的初步研究

通过野外考察、显微镜下薄片鉴定、X射线物相分析和矿物红外光谱等研究,确定了阿希金矿浊沸石化的普遍存在;根据浊沸石化发生的规律及其与矿床形成的关系,确定浊沸石化主要见于矿体的上部和外围,发育在地热流体系统的边缘和演化晚期,可作为寻找浅成低温热液型金矿的标志之一。导致阿希金矿浊沸石化的流体性质与热泉型金矿成矿流体和现代地热田类似,流体作用发生在石炭纪,证明西天山地区具有良好的浅成低温热液型金矿的形成和保存环境,因此找矿前景较好。

Colloidal gold as a permanent marker of cells

Summary We have demonstrated that colloidal gold-labelled serum proteins are taken up by a number of cells in cultures established from the postnatal rodent neopallium. The colloidal gold enters and remains within secondary lysosomes over extended periods of time and, as well, persists after the subculture of these cells. The cell types that readily take up the label in our culture system are type-1 astrocytes, glial precursor cells and macrophages, whereas, only a small number of oligodendrocytes take up the label. The use of serum proteins to introduce colloidal gold into cells therefore seems to be a convenient and easy way to permanently mark cells.
