The fast Z-scan method for studying working catalytic reactors with high energy X-ray diffraction: ZSM-5 in the methanol to gasoline process
22-05-2013 | David S. Wragg; Francesca L. Bleken; Matthew G. O'Brien; Marco Di Michiel; Helmer Fjellvåg; Unni Olsbye, Physical Chemistry Chemical Physics, 2013
The methanol to gasoline process over the zeolite catalyst ZSM-5 in a lab-sized reactor bed (4 mm diameter) has been studied in operando with high energy synchrotron X-ray diffraction. The fast z-scan method was used, scanning the reactor repeatedly and at speed through the X-ray beam. The ...
Bis(phosphine)boronium salts. Synthesis, Structures and Co-ordination Chemistry
22-05-2013 | Timothy A Shuttleworth; Miguel A. Huertos; Indrek Pernik; Rowan D Young; Andrew Weller, Dalton Transactions, 2013
The synthesis of a range of bis(phosphine)boronium salts is reported [(R2HP)2BH2][X] (R = Ph, tBu, Cy) in which the counter anion is also varied (X– = Br–, [OTf]–, [BArF4]–, ArF = 3,5-(CF3)2C6H3). Characterization in the solid–state by X-ray diffraction suggests there are weak hydrogen bonds ...
Synthesis and structural exploration of disulfide bridged [2n] pillararene type molecules
22-05-2013 | Mahendra Sonawane; Jeroen Jacobs; Joice Thomas; Luc Van Meervelt; Wim Dehaen, Chemical Communication, 2013
Disulfide bridged pillararene type macrocycles were synthesised starting from 1,4-dialkoxybenzene and sulfur monochloride. The structure was determined using X-ray diffraction analysis.
Copper Nanocubes and Nanostrctured Cuprous Oxide Prepared by Surfactant-Assited Electrochemical Deposition
22-05-2013 | Binbin Luo; Xueming Li; Xianli Li; Longping Xue; Shanya Li; Xiaolin Li, CrystEngComm, 2013
An interesting shape evolution between Cu crystals and Cu2O crystals was realized by electrodeposition and copper nanocubes (Cu NCs) with a size of 150 nm～1000 nm were successfully fabricated. Cyclic voltammogram (CV), X-ray diffraction (XRD), scanning electron microscopy (SEM), energy ...
Electrical transport properties of microwave-synthesized Bi2Se3-xTex nanosheet
22-05-2013 | Haiming Xu; Gang Chen; Rencheng Jin; Dahong Chen; Jian Pei; Yu Wang, CrystEngComm, 2013
Tellurium (Te) doped bismuth selenide (Bi2Se3-xTex) nanosheets have been successfully synthesized by the microwave-assisted method in the presence of ethylene glycol (EG). The obtained products were characterized by powder X-ray diffraction (XRD), field-emission scanning electron microscopy ...
Luminescence and photometric characterization of K+ compensated CaMoO4:Dy3+ nanophosphors
22-05-2013 | S. Dutta; S. Som; S. K. Sharma, Dalton Transactions, 2013
A series of CaMoO4 phosphors doped with trivalent dysprosium (Dy3+) and codoped with potassium (K+) ions were prepared by hydrothermal method. The nanostructures of the as-synthesized phosphors were investigated by X-ray diffraction (XRD). The results reveal that the obtained powder phosphors ...
Two Acentric (6, 3) Topological 2-D Frameworks with Imidazole-containing Tripodal ligand and their Ferroelectric Propertie
22-05-2013 | Yun Zhi Tang, Dalton Transactions, 2013
Hydrothermal reaction of three-connecting ligands 1,3,5-tris(1-imidazolyl) benzene (tib) and MnSO4 or CoSO4.7H2O provide two new metal-organic frameworks, {[Mn(tib)2(H2O)4]SO4}n (1) and {[Co(tib)2(H2O)4]SO4}n (2). Single-crystal X-ray diffraction studies reveal that complexes 1 and 2 belong ...
In situ XRD studies of nanocrystallization of Fe-based metallic glass: a comparative study by reciprocal and direct space methods
22-05-2013 | Jozef Bednarcik; Stefan Michalik; Vladimir Kolesar; Uta Rütt; Hermann Franz, Physical Chemistry Chemical Physics, 2013
Structural changes occurring in an Fe72.5Cu1Nb2Mo2Si15.5B7 alloy during a combination of constant rate heating (20 K min−1) and isothermal holding at 500 and 520 °C were investigated using in situ high-energy X-ray diffraction. We found that the ferromagnetic-to-paramagnetic transition of the ...
