Black-box determination of temperature-dependent susceptibilities for crystalline organic radicals with complex magnetic topologies

20.10.2016 | Thomas Dresselhaus; Steffen Eusterwiemann; David R. Matuschek; Constantin G. Daniliuc; Oliver Janka; Rainer Pöttgen; ..., Physical Chemistry Chemical Physics, 2016

In all but the simplest crystal structures, the identification of all relevant interactions between magnetic sites as well as the setup of magnetic model spaces, which are necessary for modeling macroscopic magnetism, are tedious and error-prone tasks. Here, we present a procedure to generate ...


Theoretical and experimental investigations of rate coefficients of O(1D) + CH4 at low temperature

20.10.2016 | Qingyong Meng; Kevin M. Hickson; Kejie Shao; Jean-Christophe Loison; Dong H. Zhang, Physical Chemistry Chemical Physics, 2016

The rate coefficients of the barrierless O(1D) + CH4 reaction are determined both theoretically and experimentally at 50–296 K. For the calculations, ring polymer molecular dynamics (RPMD) simulations are performed on the basis of a new neural network potential energy surface (PES) in the ...


Carbon induced selective regulation of cobalt-based Fischer-Tropsch catalysts by ethylene treatment

20.10.2016 | Peng Zhai; Pei-Pei Chen; Jinglin Xie; Jinxun Liu; H Zhao; Lili Lin; Bo Zhao; Hai-Yan Su; Qingjun Zhu; weixue Li; Ding Ma, Faraday Discussions, 2016

Various carbonaceous species were controllably deposited on Co/Al2O3 catalysts using ethylene as carbon source during the activation process for Fischer-Tropsch synthesis (FTS). Atomic, polymeric and graphitic carbon were distinguished by Raman, thermoanalysis and temperature programmed ...


Hydrodynamic Thermal Confinement: Creating Thermo-Chemical Microenvironments on Surfaces

18.10.2016 | Julien Cors; Ariane Stucki; Govind V. Kaigala, Chemical Communication, 2016

We present a new, general concept termed Hydrodynamic Thermal Confinement (HTC), and its implementation for the creation microscale dynamic thermo-chemical microenvironments on biological surfaces. HTC is based on a scanning probe and operates under physiological conditions. The temperature can ...


Sulfate Formation Catalyzed by Coal Fly Ash, Mineral Dust and Iron (III) Oxide: Variable Influence of Temperature and Light

18.10.2016 | Aruni Gankanda; Ellen Coddens; David Michael Cwiertny; Vicki Grassian, Journal of Environmental Monitoring, 2016

Recent atmospheric field and modeling studies have highlighted a lack of understanding of the processes responsible for high levels of sulfate aerosol in the atmosphere, ultimately arising from a dearth of experimental data on such processes. Here we investigated the effect of temperature and ...


Rational Design of MnO2@MnO2 Hierarchical Nanomaterials and Their Catalytic Activities

18.10.2016 | Bentian Zhang; Gao Cheng; wenjin Ye; Xiaoying Zheng; hengfa Liu; Ming Sun; Lin Yu; Yuying Zheng; Xiaoling Cheng, Dalton Transactions, 2016

Hierarchical structure materials have special properties and possess potential application in the catalytic and electrochemical fields. Herein, two kind of hierarchical core-shell nanostructures, lavender-like α-MnO2@α-MnO2 and balsam pear-like α-MnO2@γ-MnO2, were prepared by a facile ...


Intramolecular 5-exo, 7-endo-dig Transition Metal-Free Cyclization Sequence of (2-Alkynylphenyl) Benzyl Ethers: Synthesis of Seven-Membered Fused Benzo[b]furans

18.10.2016 | Rafaela Gai; Roberto do Carmo; Jose Neto; Thiago Acunha; Bernardo Almeida Iglesias; Davi Fernando Back; Gilson Zeni, Green Chemistry, 2016

Base-promoted cyclization of (2-alkynylphenyl) benzyl ethers was studied in details. The effects of solvent, base, temperature, reaction time and amount of base on the efficacy of the cyclization reaction was analyzed and a new base-solvent system (tert-BuOK/DMSO) for effective cyclization of ...


Initial dissolution of D2O at the gas–liquid interface of the ionic liquid [C4min][NTf2] associated with hydrogen-bond network formation

18.10.2016 | H. Ohoyama; T. Teramoto, Physical Chemistry Chemical Physics, 2016

We have studied the initial dissolution of D2O at the interfacial surface of the flowing jet sheet beam of the ionic liquid (IL) [C4min][NTf2] using the King and Wells method as a function of both the temperature and collision energy of the IL. The initial dissolution probability of D2O into the ...


Decomposition of 2-naphthol in water by TiO2 modified with MnOx and CeOy

17.10.2016 | Author(s): Mimori Shiohara, Toshihiro Isobe, Sachiko Matsushita, Akira Nakajima, Materials Chemistry and Physics, 2016

Publication date: 1 November 2016 Source:Materials Chemistry and Physics, Volume 183 Author(s): Mimori Shiohara, Toshihiro Isobe, Sachiko Matsushita, Akira Nakajima Clusters of MnO x and CeO y were modified onto TiO2 (rutile) surface by chemisorption calcination cycle processing. ...


Effect of deposition temperature on the structural, morphological and optical band gap of lead selenide thin films synthesized by chemical bath deposition method

17.10.2016 | Author(s): Fekadu Gashaw Hone, Francis Kofi Ampong, Materials Chemistry and Physics, 2016

Publication date: 1 November 2016 Source:Materials Chemistry and Physics, Volume 183 Author(s): Fekadu Gashaw Hone, Francis Kofi Ampong Lead selenide (PbSe) nanocrystalline thin films have been deposited on silica glass substrates by the chemical bath deposition technique. The samples ...
