Abnormal site occupancy and high performance in warm WLEDs of a novel red phosphor, NaHF2:Mn4+, synthesized at room temperature

20-Jan-2018 | Luqing Xi; Yuexiao Pan; Mengmeng Zhu; Hongzhou Lian; Jun Lin, Dalton Transactions, 2018

A novel red phosphor, NaHF2:Mn4+ (NHF:Mn), was obtained via substituting Na+ located at the center of the octahedron coordinated with six F− ions with Mn4+ in the host lattice of NHF. The phase purity and the exact composition of the obtained NHF:Mn were confirmed by X-ray powder diffraction ...

Low-temperature CO oxidation over CeO2 and CeO2@Co3O4 core–shell microspheres

20-Jan-2018 | Lu Zhang; Li Zhang; Guancheng Xu; Chi Zhang; Xin Li; Zhipeng Sun; Dianzeng Jia, New Journal of Chemistry, 2018

Mesoporous CeO2 core–shell microspheres were obtained by pyrolysis of a Ce–asparagine coordination polymer precursor. Then, upon a sheath-coating process via solvothermal treatment with Co(CH3COO)2·4H2O, Co3O4 species were uniformly dispersed on the CeO2 core–shell microsphere surface to generate ...

A novel methodology for fabrication of Ag–polypyrrole core–shell nanosphere using microemulsion system and evaluation of its antibacterial application

19-Jan-2018 | Alireza Salabat; Farid Mirhoseini; Mohammad Arjomandzadegan; Elham Jiryaei, New Journal of Chemistry, 2018

In this study, a new microemulsion route was applied to synthesize Ag–polypyrrole (PPy) core–shell nanospheres at room temperature. In this method, colloidal Ag nanoparticles, which were prepared in a water-in-pyrrole microemulsion, were added to the aqueous solution of CTAB to form a ...

Impact of oxygen chemistry on model interstellar grain surfaces

19-Jan-2018 | A. Rosu-Finsen; M. R. S. McCoustra, Physical Chemistry Chemical Physics, 2018

Temperature-programmed desorption (TPD) and reflection–absorption infrared spectroscopy (RAIRS) are used to probe the effect of atomic and molecular oxygen (O and O2) beams on amorphous silica (aSiO2) and water (H2O) surfaces (porous-amorphous solid water; p-ASW, compact amorphous solid water; ...

CuOTf-mediated intramolecular diborene hydroarylation

19-Jan-2018 | Sunewang Rixin Wang; Merle Arrowsmith; Holger Braunschweig; Rian D. Dewhurst; Valerie Paprocki; Lena Winner, Chemical Communication, 2018

Upon complexation to CuOTf, a PMe3-stabilized bis(9-anthryl) diborene slowly undergoes an intramolecular hydroarylation reaction at room temperature. Subsequent triflation of the B–H bond with CuOTf, followed by a PMe3 transfer, finally yields a cyclic sp2–sp3 boryl-substituted boronium triflate ...

An argyrodite-type Ag9GaSe6 liquid-like material with ultralow thermal conductivity and high thermoelectric performance

19-Jan-2018 | Binbin Jiang; Pengfei Qiu; Hongyi Chen; Qihao Zhang; Kunpeng Zhao; Dudi Ren; Xun Shi; Lidong Chen, Chemical Communication, 2018

We report a ternary argyrodite-type Ag9GaSe6 compound as a promising thermoelectric material in a moderate temperature range. Due to high carrier mobility and ultralow lattice thermal conductivity, a maximum ZT of 1.1 was obtained with stoichiometric Ag9GaSe6 at 800 K. Via introducing slight ...

Facile preparation and dehydrogenation of unsolvated KB3H8

19-Jan-2018 | Xiongfei Zheng; Yanjing Yang; Fengqi Zhao; Fang Fang; Yanhui Guo, Chemical Communication, 2018

An efficient synthesis of unsolvated KB3H8 was achieved by the reaction of a liquid K–Na alloy with BH3·THF at room temperature. KB3H8 was found to release hydrogen and minor boranes by subsequent cleavage of its B–H and B–H–B bonds during pyrolysis, and yield K2B12H12 as a major product.

Anisotropic thermophoresis

19-Jan-2018 | Zihan Tan; Mingcheng Yang; Marisol Ripoll, Soft Matter, 2018

Colloidal migration in a temperature gradient is referred to as thermophoresis. In contrast to particles with a spherical shape, we show that elongated colloids may have a thermophoretic response that varies with the colloid orientation. Remarkably, this can translate into a non-vanishing ...
