N‐Heterocyclic Carbene Formation Induced Fluorescent and Colorimetric Sensing of Fluoride Using Perimidinium Derivatives

24-10-2014 | Dawei Zhang, Haiqiang Yang, Alexandre Martinez, Kelsey Jamieson, Jean‐Pierre Dutasta, Guohua Gao, Chemistry - A European Journal, 2014

Abstract In this study, two perimidinium derivatives (1 and 2) were designed, synthesized, and developed as efficient fluorescent and colorimetric chemodosisensors for F− in DMSO or more competitive media (DMSO containing 10 % water). In the presence of F−, the yellow and non‐fluorescent ...

Enhanced Ethylene Photodegradation Performance of g‐C3N4–Ag3PO4 Composites with Direct Z‐Scheme Configuration

24-10-2014 | Xuxing Chen , Xintang Huang, Zhiguo Yi, Chemistry - A European Journal, 2014

Abstract Photocatalytic oxidation of ethylene continues to be a challenge at the frontier of chemistry. In a previous report, a simple Ag3PO4 semiconductor material was shown to have strong photooxidative properties and efficiently oxidised water and decomposed organics in aqueous solution ...

Thymol treatment of bacteria prior to matrix‐assisted laser desorption/ionization time‐of‐flight mass spectrometric analysis aids in identifying certain bacteria at the subspecies level

24-10-2014 | Ricky D. Holland, Jon G. Wilkes, Willie M. Cooper, Pierre Alusta, Anna Williams, Bruce Pearce, Michael Beaudoin, Dan ..., Rapid Communications in Mass Spectrometry, 2014

RATIONALE The identification of bacteria based on mass spectra produced by matrix‐assisted laser desorption/ionization time‐of‐flight mass spectrometry (MALDI‐TOFMS) has become routine since its introduction in 1996. The major drawback is that bacterial patterns produced by MALDI are dependent ...

Can Lowering the Injection Brine Salinity Further Increase Oil Recovery by Surfactant Injection under Otherwise Similar Conditions?

23-10-2014 | Annette Meland Johannessen; Kristine Spildo, Energy & Fuels, 2014

It is well-established that injecting water with significantly lower salinity than the formation water salinity may give increased oil recovery. Although less well studied, the observed low-salinity effect has drawn attention to possible benefits from combining low-salinity water with traditional ...

Molecular Recognition and Scavenging of Arsenate from Aqueous Solution Using Dimetallic Receptors

22-10-2014 | Chris D. Moffat, Dominik J. Weiss, Arun Shivalingam, Andrew J. P. White, Pascal Salaün, Ramon Vilar, Chemistry - A European Journal, 2014

Abstract A series of copper(II), nickel(II) and zinc(II) dimetallic complexes were prepared and their affinities towards arsenate investigated. Indicator displacement assays (IDAs) were carried out to establish the complexes with best affinities towards arsenate. A di‐zinc complex (3) was ...

Supramolecular photochemistry: from molecular crystals to water-soluble capsules

22-10-2014 | V. Ramamurthy; Shipra Gupta, Chemical Society Reviews, 2014

Photochemical and photophysical behavior of molecules in supramolecular assemblies are different and more selective than in gas and isotropic solution phases. Knowledge of the inherent electronic and steric properties of the reactant is insufficient to predict the excited state behavior of ...

Hydration of Cyanide Anion: An Ab Initio Quantum Mechanical Charge Field Molecular Dynamics Study

22-10-2014 | Syed Tarique Moin; Thomas Hofer, Physical Chemistry Chemical Physics, 2014

This paper presents an ab initio quantum mechanical charge field molecular dynamics simulation study of the cyanide anion CN- in aqueous solution where hydrogen bond formation plays a dominant role in the hydration process. Preferential orientation of water hydrogens compared to oxygen atoms was ...

Asphaltene Subfractions Responsible for Stabilizing Water-in-Crude Oil Emulsions. Part 1: Interfacial Behaviors

22-10-2014 | Fan Yang; Plamen Tchoukov; Erica Pensini; Tadeusz Dabros; Jan Czarnecki; Jacob Masliyah; Zhenghe Xu, Energy & Fuels, 2014

The asphaltene fraction of crude oil is commonly considered to be responsible for the formation of highly undesirable, stable water-in-crude oil emulsions and rag layers. We developed a new procedure for subfractionation of asphaltenes based on their interfacial activity. The most interfacially ...

Single‐Mode Lasing from Colloidal Water‐Soluble CdSe/CdS Quantum Dot‐in‐Rods

21-10-2014 | Francesco Di Stasio, Joel Q. Grim, Vladimir Lesnyak, Prachi Rastogi, Liberato Manna, Iwan Moreels, Roman Krahne, Small, 2014

Core–shell CdSe/CdS nanocrystals are a very promising material for light emitting applications. Their solution‐phase synthesis is based on surface‐stabilizing ligands that make them soluble in organic solvents, like toluene or chloroform. However, solubility of these materials in water provides ...
