Co(III) protoporphyrin IX chloride in solution: Spin-state and metal coordination revealed from resonant inelastic X-ray scattering and electronic structure calculations

17-12-2014 | Kaan Atak; Ronny Golnak; Jie Xiao; Mika Pflüger; Tim Brandenburg; Bernd Winter; Emad Flear Aziz, Physical Chemistry Chemical Physics, 2014

The local electronic structure of the cobalt centre-ion of Co(III) protoporphyrin IX chloride dissolved in dimethyl sulfoxide (DMSO) liquid solution is studied by resonant inelastic X-ray scattering (RIXS) spectroscopy at the cobalt L-edge. The resulting cobalt 2p partial-fluorescence-yield (PFY) ...

Chloride in Lead Chloride-Derived Organo-Metal Halides for Perovskite-Absorber Solar Cells

12-12-2014 | Eva L. Unger; Andrea R. Bowring; Christopher J. Tassone; Vanessa L. Pool; Aryeh Gold-Parker; Rongrong Cheacharoen; K ..., Chemistry of Materials, 2014

Organo-metal halide perovskites are an intriguing class of materials that have recently been explored for their potential in solar energy conversion. Within a very short period of intensive research, highly efficient solar cell devices have been demonstrated. One of the heavily debated questions ...

Influence of preparation methods on the electrical and nanomechanical properties of poly(methyl methacrylate)/multiwalled carbon nanotubes composites

11-12-2014 | Katarína Mosnáčková, Zdenko Špitálský, Jaroslav Kuliček, Jan Prokeš, Amalia Skarmoutsou, Costas A. Charitidis, Mária ..., Journal of Applied Polymer Science, 2014

ABSTRACT Poly(methyl methacrylate)/multiwalled carbon nanotubes (PMMA/MWCNT) composites were prepared by two different methods: melt mixing and solution casting. For solution casting, two different solvents, toluene and chloroform, were used to prepare PMMA solutions with different ...

Thickness, Composition, and Molecular Structure of Residual Thin Films Formed by Forced Dewetting of Ag from Glycerol/D2O Solutions

11-12-2014 | Jeanne E. Pemberton; Anoma Mudalige; Heemin Yoo, Langmuir, 2014

The thickness, composition, and interfacial molecular structure of residual thin films retained on the surface of polycrystalline Ag substrates after being forcibly dewet from glycerol/D2O solutions are investigated using contact angle measurements, ellipsometry, and polarization ...

Online mercury determination by laser-induced breakdown spectroscopy with assistance of solution cathode glow discharge

10-12-2014 | Peichao Zheng; Hongdi Liu; Jinmei Wang; Minjie Shi; Xiaomeng Wang; Bin Zhang; Rui Yang, Journal of Analytical Atomic Spectrometry, 2014

The trace mercury in aqueous solution is determined by laser-induced breakdown spectroscopy (LIBS) under the assistance of solution cathode glow discharge (SCGD) system. The aqueous solution is converted to gas phase using high voltage DC discharge, and then the generated mercury vapor is cooled ...

Charge transfer to solvent dynamics in iodide aqueous solution studied at ionization threshold

09-12-2014 | Alexander Kothe; Martin Wilke; Alexandre Moguilevski; Nicholas Engel; Bernd Winter; Igor Yu. Kiyan; Emad F. Aziz, Physical Chemistry Chemical Physics, 2014

We explore the early-time electronic relaxation in NaI aqueous solution exposed to a short UV laser pulse. Rather than initiating the charge transfer reaction by resonant photoexcitation of iodide, in the present time-resolved photoelectron spectroscopy study the charge-transfer-to-solvent (CTTS) ...

Investigation of Soil Legacy Phosphorus Transformation in Long-Term Agricultural Fields Using Sequential Fractionation, P K-edge XANES and Solution P NMR Spectroscopy

08-12-2014 | Jin Liu; Yongfeng Hu; Jianjun Yang; Dalel Abdi; Barbara J. Cade-Menun, Environmental Science & Technology, 2014

Understanding legacy phosphorus (P) build-up and draw-down from long-term fertilization is essential for effective P management. Using replicated plots from Saskatchewan, Canada, with P fertilization from 1967 to 1995 followed by either P fertilization or P cessation (1995–2010), soil P was ...

IJMS, Vol. 15, Pages 22642-22660: Highly Soluble Monoamino-Substituted Perylene Tetracarboxylic Dianhydrides: Synthesis, Optical and Electrochemical Properties

08-12-2014 | Chen, Kew-Yu ; Chang, Che-Wei, International Journal of Molecular Sciences, 2014

Three dialkylamino-substituted perylene tetracarboxylic dianhydrides with different n-alkyl chain lengths (n = 6, 12 or 18), 1a–1c, were synthesized under mild conditions in high yields and were characterized by 1H NMR, 13C NMR and high resolution mass spectroscopy. Their optical and ...

Control over Nanostructures and Associated Mesomorphic Properties of Doped Self‐Assembled Triarylamine Liquid Crystals

05-12-2014 | Yuya Domoto, Eric Busseron, Mounir Maaloum, Emilie Moulin, Nicolas Giuseppone, Chemistry - A European Journal, 2014

Abstract We have synthesized a series of triarylamine‐cored molecules equipped with an adjacent amide moiety and dendritic peripheral tails in a variety of modes. We show by 1H NMR and UV/Vis spectroscopy that their supramolecular self‐assembly can be promoted in solution upon light ...
