Valence properties of Cu and Ru in titanium-substituted LnCu3Ru4O12 (Ln = La, Pr, Nd) investigated by XANES and TGA

26-Mar-2015 | Stefan Riegg; Armin Reller; Ing. Alois Loidl; Stefan G. Ebbinghaus, Dalton Transactions, 2015

In the solid-solution series LayCu3RuxTi4-xO12+ δ (0 ≤ x ≤ 4) the Cu and Ru electronic states are highly correlated. With increasing Ru content x the system properties change from a paramagnetic insulator with colossal dielectric constant to a heavy-fermion metal. To further elucidate the ...


Surface plasmon enhanced energy transfer between gold nanorods and fluorophores: application to endocytosis study and RNA detection

26-Mar-2015 | Yinan Zhang; Guoke Wei; Jun Yu; David J. S. Birch; Yu Chen, Faraday Discussions, 2015

Previously we have demonstrated surface plasmon enhanced energy transfer between fluorophores and gold nanorods under two-photon excitation using fluorescence lifetime imaging microscopy (FLIM) in both solution and intracellular phases. These studies demonstrated that gold nanoparticle–dye energy ...


Alkyl linker effects on the coordination topology of ditopic di(2-pyridylmethyl)amine carboxylate ligands with ZnII and CuII perchlorates: polymers vs macrocycles

26-Mar-2015 | Kiattipoom Rodpun; Allan G. Blackman; Michael G. Gardiner; Eng Wui Tan; Carla J. Meledandri; Nigel T. Lucas, CrystEngComm, 2015

A series of ditopic ω-di(2-pyridylmethyl)amine carboxylic acid ligands incorporating a range of n-alkyl linkers (CnCOOH, n = 3–5, 7, 10 and 11) have been synthesised. Solution phase studies showed a 1 [ ] : [ ] 1 coordination stoichiometry between the ligands and M(ClO4)2·6H2O (M = ZnII or CuII) ...


Selective turn-off phosphorescent and colorimetric detection of mercury(II) in water by half-lantern platinum(II) complexes

26-Mar-2015 | Violeta Sicilia; Pilar Borja; Miguel Baya; José M. Casas, Dalton Transactions, 2015

The platinum(ii) half-lantern dinuclear complexes [{Pt(bzq)(μ-C7H4NS2-κN,S)}2] (A) and [{Pt(bzq)(μ-C7H4NOS-κN,S)}2] (B) [bzq = benzo[h]quinolinate, C7H4NS2 = 2-mercaptobenzothiazolate, C7H4NOS = 2-mercaptobenzoxazolate] in solution of DMSO–H2O undergo a dramatic color change from yellowish-orange ...


Ion specific effects: decoupling ion–ion and ion–water interactions

26-Mar-2015 | Jinsuk Song; Tae Hui Kang; Mahn Won Kim; Songi Han, Physical Chemistry Chemical Physics, 2015

Ion-specific effects in aqueous solution, known as the Hofmeister effect, are prevalent in diverse systems ranging from pure ionic to complex protein solutions. The objective of this paper is to explicitly demonstrate how complex ion–ion and ion–water interactions manifest themselves in the ...


Synthesis of a 12R-type Hexagonal Perovskite Solid Solution Sr3NdNb3-xTixO12-d and the Influence of Acceptor Doping on Electrical Properties

26-Mar-2015 | Adilson Luiz Chinelatto; Khalid Boulahya; Domingo Pérez-Coll; Ulises Amador; Corina Tabacaru; Simon Nicholls; Markus ..., Dalton Transactions, 2015

A solid solution forms for Sr3NdNb3-xTixO12-d with approximate limits 0 ≤ x ≤ 0.06. The system crystallizes with a 12R-type hexagonal perovskite structure in space group , as determined by neutron diffraction and selected area electron diffraction. The electrical properties of the end members ...


Optimization of charge carrier transport balance for performance improvement of PDPP3T-based polymer solar cells prepared using a hot solution

24-Mar-2015 | Jian Wang; Fujun Zhang; Miao Zhang; Wenbin Wang; Qiaoshi An; Lingliang Li; Qianqian Sun; Weihua Tang; Jian Zhang, Physical Chemistry Chemical Physics, 2015

Polymer solar cells (PSCs), with poly(diketopyrrolopyrrole-terthiophene) (PDPP3T):[6,6]-phenyl-C71-butyric acid methyl ester (PC71BM) as the active layers, were fabricated using solutions of different temperatures. The best power conversion efficiency (PCE) of the PSCs prepared using a hot ...


A dual-responsive supra-amphiphile based on a water-soluble pillar[7]arene and a naphthalene diimide-containing guest

24-Mar-2015 | Guocan Yu; Li Shao; Jiong Zhou; Bin Hua, Chemical Communication, 2015

A dual-responsive supra-amphiphile was firstly constructed based on a water-soluble pillar[7]arene and a naphthalene diimide-containing guest with a long alkyl chain and a trimethylammonium group. The morphologies of the self-assembly formed from this supra-amphiphile could be adjusted by ...


Highly efficient detection of hydrogen peroxide in solution and in the vapor phase via fluorescence quenching

24-Mar-2015 | Patrick Marks; Bhasker Radaram; Mindy Levine; Igor A Levitsky, Chemical Communication, 2015

Herein we report the highly efficient and sensitive detection of hydrogen peroxide in both aqueous solution and in the vapor phase via fluorescence quenching (turn-off mechanism) of the amplified fluorescent conjugated polymer-titanium complex induced by hydrogen peroxide. Inter- and ...


Development of Highly Thermoresponsive Fluorescence Sensor Consisting of Plasmonic Silver Nanoprisms and Poly(N-isopropylacrylamide)-Fluorophore Composites

23-Mar-2015 | Kosuke Sugawa; Ryutaro Ichikawa; Naoto Takeshima; Yoshimasa Tanoue; Joe Otsuki, Photochemical & Photobiological Sciences, 2015

We developed a new hybrid consisting of Ag nanoprisms, poly(N-isopropylacrylamide) (PNIPAm), and fluorophores via layer-by-layer assembly. The fluorescence intensity below the lower critical solution temperature (LCST) of PNIPAm was 6.4 times stronger than that above the LCST, meaning that the ...
