Mineralization of malachite green dye over visible light responsive bismuth doped TiO2–ZrO2 ferromagnetic nanocomposites

05-Mar-2015 | Archana Charanpahari; Sachin G. Ghugal; Suresh S. Umare; Rajamma Sasikala, New Journal of Chemistry, 2015

We report enhanced visible light photocatalytic activity for ferromagnetic Bi doped (1% by atomic weight) TiO2–ZrO2 nanocomposites for the degradation of malachite green in aqueous solution. X-ray diffraction, Raman and High resolution Transmission electron microscopy (HRTEM) analysis indicate ...


Polymer fullerene solution phase behaviour and film formation pathways

05-Mar-2015 | Rajeev Dattani; João T. Cabral, Soft Matter, 2015

We report the phase behaviour of polymer/fullerene/solvent ternary mixtures and its consequence for the morphology of the resulting composite thin films. We focus particularly on solutions of polystyrene (PS), C60 fullerene and toluene, which are examined by static and dynamic light scattering, ...


Electrochemical generation of Michael acceptor: A green method for the synthesis of 4-amino-3-(phenylsulfonyl)diphenylamine derivatives

05-Mar-2015 | Davood Nematollahi; Eslam Salahifar, New Journal of Chemistry, 2015

Electrochemical oxidation of 4-aminodiphenylamine in aqueous solution and in the presence of some aryl sulfinic acids as nucleophiles was studied and its reaction mechanism was discussed. Using the voltammetric data, a one-pot and environmentally friendly electrochemical approach for the ...


An open chain carboxyethyltin functionalized sandwich-type tungstophosphate based on trivacant Dawson subunit: synthesis, characterization and properties

05-Mar-2015 | jianping Bai; fang Su; Hao-Tian Zhu; hang Sun; Lan-Cui Zhang; Meiying Liu; wansheng You; Zaiming Zhu, Dalton Transactions, 2015

A Dawson sandwich-type polyoxometalate {C(NH2)3}12H4[αββα-{(Sn(C3H4O2))2Mn2(P2W15O56)2}]•22H2O (Abbreviated as SnR-Mn-P2W15), functionalized by open chain carboxyethyltin groups was first prepared in aqueous solution under conventional reaction conditions, and structurally characterized by ...


Spontaneous self-welding of silver nanowire networks

05-Mar-2015 | Baekhoon Seong; Ilkyeong Chae; Hyungdong Lee; Vu Dat Nguyen; Doyoung Byun, Physical Chemistry Chemical Physics, 2015

As an alternative to the traditional indium tin oxide transparent electrode, solution-processed metal nanowire thin film has been a promising candidate due to its flexibility. However, high contact resistance between the nanowires remains a major challenge to improve the performance. Here, we ...


“Off-On” Aggregation-Based Fluorescent Sensor for the Detection of Chloride in Water

04-Mar-2015 | Michelle M. Watt; Jeffrey M Engle; Kurtis C. Fairley; Timothy E Robitshek; Michael M Haley; Darren Johnson, Organic & Biomolecular Chemistry, 2015

Receptors selective for anions in aqueous media are a crucial component in the detection of anions for biological and environmental applications. Recent sensor designs have taken advantage of systems known to aggregate in solution, eliciting a fluorescent response. Herein, we demonstrate a ...


Synthesis, characterization and structure of nickel and copper compounds containing ligands derived from keto-enehydrazines and their catalytic application for aerobic oxidation of alcohols

04-Mar-2015 | Miguel Ángel Gaona; Francisco Montilla; Eleuterio Álvarez; Agustin Galindo, Dalton Transactions, 2015

Ligand precursors HLR,Ph (R = Me, Ph) were synthesised by condensation of acetylacetone and the corresponding N,N substituted hydrazine and were characterised spectroscopically and structurally. Both in the solid state and in solution they behave as (Z) keto-enehydrazines and this was confirmed ...


Electronic state dependence of heterogeneous electron transfer: injection from the S1 and S2 state of phlorin into TiO2

03-Mar-2015 | Jesus Nieto-Pescador; Baxter Abraham; Allen J. Pistner; Joel Rosenthal; Lars Gundlach, Physical Chemistry Chemical Physics, 2015

Ultrafast time-resolved measurements were performed on a novel pentafluorophenyl substituted 5,5-dimethyl phlorin derivative in solution and when attached to TiO2 colloidal films. The complex excited state dynamics of this porphyrinoid after S1 and S2 excitation was compared at different ...


Nanomaterial-based Biosensors using Dual Transducing Elements for Solution Phase Detection

03-Mar-2015 | Ning Li; Xiaodi Su; Yi Lu, Analyst, 2015

Biosensors incorporating nanomaterials have demonstrated superior performance compared to their conventional counterparts. Most reported sensors use nanomaterials as a single transducer of signals, while biosensor designs using dual transducing elements have emerged as new approaches to further ...


Remarkable Distinctions in the Heat-induced Phase Transition Processes of Two Poly(2-isopropyl-2-oxazoline)-based Mixed Aqueous Solutions

03-Mar-2015 | Tianjiao LI; Hui Tang; peiyi wu, Soft Matter, 2015

Detailed phase transition processes of poly (2-isopropyl-2-oxazoline) (PIPOZ)/ Poly (N-isopropylacrylamide) (PNIPAM) and PIPOZ/ poly (N-vinylcaprolactam) (PVCL) mixtures in aqueous solution were investigated by DSC, temperature-variable 1H-NMR, optical microscopy and FT-IR spectroscopy ...
