Hepatoprotective and Urease Inhibitory Activities of Garlic Conjugated Gold Nanoparticles

29-Apr-2015 | Muhammad Raza Shah; Mohammad Ateeque; Hamid Ali; Nurul Kabir; Ajmal Khan; Said Nadeem, New Journal of Chemistry, 2015

A robust synthetic method is reported for the synthesis of highly stable, poly disperse and spherical gold nanoparticles conjugated to aqueous garlic extract (G-AuNPs). Ionic solution of gold was mixed and stirred with dilute aqueous garlic extract at room temperature for 4 hours. The G-AuNPs ...

Fabrication of TiO2 nanotubes-assembled hierarchical microspheres with enhanced photocatalytic degradation activity

28-Apr-2015 | Liangpeng Wu; Yong Qiu; Min Xi; Xinjun Li; Chaoping Cen, New Journal of Chemistry, 2015

TiO2 nanotubes-assembled hierarchical microspheres were fabricated by a one step hydrothermal route using P25 in NaOH aqueous solution with the assistance of H2O2, followed by temperature-programmed calcinations treatment at 400 °C. The photocatalytic activity of the sample was investigated by ...

NMR investigation of boron impurities in refined metallurgical grade silicon

27-Apr-2015 | Hans‐Joachim Grafe, Wolfgang Löser, Steffen Schmitz, Miroslava Sakaliyska, Sabine Wurmehl, Stefan Eisert, Birk Reich ..., physica status solidi (a), 2015

The nuclear magnetic resonance (NMR) method was applied for tracking boron impurities in the refining process of metallurgical grade (MG) silicon. From the NMR signal of the 11B isotope at an operating temperature 4.2 K, the boron concentration can be estimated down to the order of 1–10 wppm B. ...

Growth Rate Dispersion at the Single‐Crystal Level

27-Apr-2015 | Emilie Bobo, Samuel Petit, Gérard Coquerel, Chemical Engineering & Technology, 2015

Abstract Evidence of growth rate dispersion for symmetry‐related opposite faces of centrosymmetric single crystals of ammonium perchlorate is provided. Crystallization experiments conducted by evaporation of a stagnant aqueous solution at room temperature show that some faces have high and ...

Clustering and Dissolution of Triazole Branched Poly(ethyl methylacrylate)

24-Apr-2015 | Jungju Ryu, Seo‐Hyun Jung, Jae Hyun Sim, Hyung‐il Lee, Daewon Sohn, Macromolecular Chemistry and Physics, 2015

The solution properties of the multiresponsive polymer P1 (poly(2‐((3‐(1‐(2‐(dimethylamino)ethyl)‐1H‐1,2,3‐triazol‐4‐yl)propanoyl)oxy)ethyl methacrylate) are studied by small angle neutron scattering (SANS) and dynamic light scattering (DLS). The P1 solution exhibits a phase transition above ...

The effects of long term exposure of flax fiber reinforced polymer to salt solution at high temperature on tensile properties

24-Apr-2015 | Kenneth Mak, Amir Fam, Colin MacDougall, Polymer Composites, 2015

Most research on natural fiber composites has been primarily conducted on randomly‐oriented fibers. This study is focused on the short‐ and long‐term performances of Flax Fiber Reinforced Polymer (Flax‐FRP) made from continuous unidirectional fiber mats, and compares it to Glass‐FRP composite. ...

Synthesis and Reactivity of Thioether-Dithiolate-Bridged Multi-iron Complexes

23-Apr-2015 | Ying Li; Yahui Zhang; Dawei Yang; Yang Li; Puhua Sun; Baomin Wang; Jingping Qu, Organometallics, 2015

The novel thioether-dithiolate-bridged diiron complex [Cp*Fe(μ-1κ3SSS′:2κ2SS-tpdt)FeCp*] (1, Cp* = η5-C5Me5; tpdt = S(CH2CH2S−)2) has been prepared by the reaction of [Cp*FeCl]2 with Li2(tpdt) in THF. Given the thermodynamic instability of 1, a one-electron oxidation was performed with Fc·PF6 (Fc ...

Perovskite Microdisk Microlasers Self‐Assembled from Solution

22-Apr-2015 | Qing Liao, Ke Hu, Haihua Zhang, Xuedong Wang, Jiannian Yao, Hongbing Fu, Advanced Materials, 2015

Single‐crystalline square microdisks of CH3NH3PbBr3 are prepared by using a one‐step solution self‐assembly method. Single mode lasing at 557 nm is achieved based on a built‐in whispering gallery mode microresonator at room temperature. By partial replacement of Br with Cl, lasing wavelengths ...

Molecules, Vol. 20, Pages 7379-7395: Copper(I) Complexes of Mesoionic Carbene: Structural Characterization and Catalytic Hydrosilylation Reactions

22-Apr-2015 | Hohloch, Stephan ; Duecker, Fenja Leena; van der Meer, Margarethe ; Sarkar, Biprajit, Molecules, 2015

Two series of different Cu(I)-complexes of “click” derived mesoionic carbenes are reported. Halide complexes of the type (MIC)CuI (with MIC = 1,4-(2,6-diisopropyl)-phenyl-3-methyl-1,2,3-triazol-5-ylidene (for 1b), 1-benzyl-3-methyl-4-phenyl-1,2,3-triazol-5-ylidene (for 1c)) and cationic complexes ...
