在金纳米粒子(AuNPs)上经苯硫酚衍生物(3,4二羟基苯基-偶氮-苯硫酚,DAT)自组装制得了一种新型纳米复合物,用于修饰玻璃碳电极(GCE/AuNP-DAT).采用循环伏安法研究了该新型电极的性质,并将其用作异丙肾上腺素(IP)电催化剂,考察了该纳米复合物的电催化活性,从而得到反应机理和催化反应速率常数.由于GCE/Au NP-DAT电极对尿酸氧化没有电催化活性,因此可将IP的氧化信号从该改进电极中分离出来,从而排除了尿酸对IP测定的干扰.该电极可作为传感器,当用于差动脉冲伏安法测定IP时,线性动态范围为1.0–1500.0μmol/L,检测极限为0.46μmol/L.

A chemically modified carbon paste electrode (CPE), consisting of 2,2'-[ (1E)- (1,2- phenylenebis (azanylylidene)] bis (methanylylidene)]bis (benzene-1,4-diol) (PBD) and multiwalled carbon nano-tubes (CNTs), was used to study the electrocatalytic oxidation of dopamine using cyclic voltamme-try, chronoamperometry, and differential pulse voltammetry (DPV). First, the electrochemical be-havior of the modified electrode was investigated in buffer solution. Then the diffusion coefficient, electrocatalytic rate constant, and electron-transfer coefficient for dopamine oxidation at the sur-face of the PBD-modified CNT paste electrode were determined using electrochemical approaches. It was found that under optimum conditions (pH = 7.0), the oxidation of dopamine at the surface of such an electrode occurred at about 200 mV, lower than that of an unmodified CPE. DPV of dopa-mine at the modified electrode exhibited two linear dynamic ranges, with a detection limit of 1.0 μmol/L. Finally, DPV was used successfully for the simultaneous determination of dopamine, uric acid, and folic acid at the modified electrode, and detection limits of 1.0, 1.2, and 2.7 μmol/L were obtained for dopamine, uric acid, and folic acid, respectively. This method was also used for the determination of dopamine in a pharmaceutical preparation using the standard addition method.

The purpose of this research is to look into the augmentation of silica nanoparticles(NPs)with low salinity(LowSal)brine for EOR.A series of analyses,including oil/water interfacial tension(IFT)and rock wettability tests were undertaken to determine an optimal dispersion to flood into a porous carbonate core with a defined pore size *** 60℃and 14.5 psi,the maximum drop(i.e.,roughly 12.5 mN/m)in oil/water IFT by 0.3 wt%brine occurred,but when 0.08 wt%silica was added to the brine,the IFT reduced to 14.51 mN/m at 60℃and 14.5 *** wettability analysis revealed a significant reduction in contact angle,from 142°to 72°and 59°,using 0.04 and 0.08 wt%silica in LowSal brine,but the extent reduced by brine alone was *** results of rock pore size characterization were discussed in terms of the accomplishment of operating EOR in the porous medium in the presence of *** addition of 0.08 wt%silica to the injected brine resulted in an additional oil recovery of 16.3%OOIP as well as a significant shift in the endpoints/cross-points of the oil/water relative permeability *** findings of this research might help improve oil recovery from asphaltenic oil reservoirs or,more environmentally friendly,remediate petroleum crude-oil polluted soil.

Islet transplantation as a promising treatment for type 1 diabetes has received widespread attention. Oxidative stress plays an essential role in cell injury during islet isolation and transplantation procedures. Antioxidants have been used in various studies to improve islet transplantation procedures. The present study reviews the role of oxidative stress and the benefits of antioxidants in islet transplantation procedures. The bibliographical databases Pubmed and Scopus were searched up to November 2008. All relevant human and animal in-vivo and in-vitro studies, which investigated antioxidants on islets, were included. Almost all the tested antioxidants used in the in-vitro studies enhanced islet viability and insulin secretion. Better control of blood glucose after transplantation was the major outcome of antioxidant therapy in all in-vivo studies. The data also indicated that antioxidants improved islet transplantation procedures. Although there is still insuffi cient evidence to draw definitive conclusions about the efficacy of individual supplements, the benefi ts of antioxidants in islet isolation procedures cannot be ignored.

Isoquinoline reacts with dialkyl acetylenedicarboxylates in the presence of kojic acid or8-hydroxyquinoline to generate 1,2-dihydroisoquinoline derivatives. The simplicity, mild reaction conditions and high yields of products make it an interesting process compared to other approaches. The compounds have been analyzed for antibacterial activity against Gram negative and Gram positive bacteria. The results indicated that 1,2-dihydroisoquinolines derived from kojic acid are effective against all of the studied bacteria especially against Bacillus subtilis, while the products obtained from8-hydroxyquinoline are active only against Gram positive bacteria.

The extended discrete element method (XDEM) multi-physics and multi-scale simulation platform is being developed at the Institute of Computational Engineering, the University of Luxembourg. The platform is an advanced multi-physics simulation technology that combines flexibility and versatility to establish the next generation of multi-physics and multi-scale simulation tools. For this purpose, the simulation framework relies on coupling various predictive tools based on an Eulerian and Lagrangian approach. The Euleria n approach represents the wide field of con tinuum models;the Lagra ngian approach is perfect for characterising discrete phases. Continuum models thus include classical simulation tools, such as computational fluid dynamics simulation and finite element analysis, while an extended configuration of the classical discrete element method addresses the discrete (e.g., particulate) phase. Apart from predicting the trajectories of in dividual particles, XDEM-suite extends the application of the XDEM to estimating the thermodynamic state of each particle using advanced and optimised algorithms. The thermodynamic state may include temperature and species distributions due to chemical reaction and external heat sources. Hence, coupling these extended features with either computational fluid dynamics simulation or finite element analysis opens a wide range of applications as diverse as pharmaceuticals, agriculture, food processing, mining, construction and agricultural machinery, metals manufacturing, energy production and systems biology.
