鄂尔多斯盆地陇东地区长9油层组储层沉积学特征

通过对36口井的岩心观察描述和108件样品的铸体薄片鉴定、扫描电镜、物性、孔隙结构分析的综合研究,表明鄂尔多斯盆地陇东地区三叠系延长组长9油层组属于浅水三角洲沉积体系,储集岩主要为三角洲平原水上和前缘水下分流河道微相的灰色中-细粒岩屑长石砂岩,储集空间以剩余原生粒间孔为主,次为粒间和粒内溶孔,少量铸模孔,喉道以中、细喉为主,储层物性中等略偏差,属中-低孔、低渗孔隙型储层。储层发育受沉积作用、砂体厚度和成岩作用复合控制,可划分为4类储层,有利于储层发育的沉积微相依次为水下分流河道、水上分流河道及河口坝砂体,好的Ⅰ、Ⅱ类储层主要发育于水下分流河道砂体中。     

Bi7O9I3的制备及光催化氮氧化物去除

利用简易溶剂热—球磨法制备了n型半导体Bi₇O₉I₃,并对其组分、光学性质、电化学性质进行了分析表征。结果表明：球磨使粉末材料的颗粒尺寸减小、带隙略微变宽,产生的光生电子和空穴更容易迁移和分离,这都有助于增强体系的光催化氮氧化物（NO_x）的去除能力。在可见光照射下,溶剂热—球磨法制备的Bi₇O₉I₃可去除体积分数40%的NO,明显高于溶剂热法制备的Bi₇O₉I₃的活性。物种捕捉试验表明,光催化过程中起主要作用的是超氧自由基和空穴,据此初步推测了Bi₇O₉I₃的光催化机制。重复试验表明,溶剂热—球磨法制备的催化剂具有良好的重复利用性和结构稳定性。     

Characterization of the Expression of CTRP9, a Paralog of Adiponectin

Adiponectin is one of the hormones secreted exclusively by the adipose tissue with anti-diabetic anti-inflammatory, anti-atherogenic, anti-atherosclerotic, and insulin-sensitizing effects. Adiponectin has structural features including a signal peptide at the N terminus, a short variable region, a collagenous domain, and a C-terminal globular domain homologous to Clq. The family of proteins containing this globular domain is called the C1q/tumor necrosis factor-a-related proteins （CTRP）. Among all the CTRPs characterized so far, the CTRP9 protein has the highest homology to adiponectin. However, little is known about the functions of CTRP9. This study examines the tissue expression of CTRP9 as well as the expression of CTRP9 during mouse development and 3T3-L1 preadipocyte differentiation. The effects of LPS, TNFα, and starvation on the expression of CTRP9 were also investigated. CTRP9 mRNA is shown to be expressed in a variety of tissues including the adipose tissues. The expression profile of CTRP9 differs from that of adiponectin, implying that they are functionally diverse although structurally homologous.

Spectrophotometric determination of aluminium with 2,3,7-trihydroxy-9-[4-(2,4-dihydroxy)phenylazo] phenylfluorone

The conditions of color reaction of Aluminium(III) with a new organic reagent 2,3,7-trihydroxy-9-[2,4-dihydroxy)phenylazo] phenylfluorone (ARPF) in the presence of cetyltrimethyammonium bromide (CTMAB) were studied. It was found that Aluminium(III) reacts with ARPF and CTMAB in pH 6.5 HAc-NaAc buffer solution to form a 1∶2 red complex with maximum absorption at 562 nm. The molar absorptivity is 1.10×10⁵ L·mol⁻¹·cm⁻¹. Beer’s law is obeyed in the range of 0–5.5 μg Al(III) per 25 mL. The method has been applied to determination of Aluminium in the limestone with satisfactory results.
