Manipulation of Birefringence via Substitution of Sr2+ by Pb2+ Based on the Structure Model of LiSr1-xPbxBO3 (0 [less-than-or-equal] x [less-than-or-equal] 0.5)

05.05.2016 | Miriding Mutailipu; Dianwei Hou; Min Zhang; Zhihua Yang; ShiLie Pan, New Journal of Chemistry, 2016

A series of LiSr1-xPbxBO3 (x = 0.138, 0.285, 0.320, 0.379, 0.417, 0.5) crystals have been obtained by a high-temperature solution reaction with spontaneous nucleation technique, and the crystal structures were solved from single-crystal X-ray diffraction. Through a great deal of experiments, the ...

Hydrogen adsorption on two catalysts for the ortho- to parahydrogen conversion: Cr-doped silica and ferric oxide gel

05.05.2016 | Monika A Hartl; R. Chad Gillis; Luke L. Daemen; Daniel P Olds; Katharine Page; Stefan Carlson; Yongqiang Cheng; Thom ..., Physical Chemistry Chemical Physics, 2016

Molecular hydrogen exists in two spin-rotation coupled states: parahydrogen and orthohydrogen. Due to the variation of energy with rotational level, the occupation of ortho- and parahydrogen states is temperature dependent, with parahydrogen being the dominant species at low temperatures. The ...

Enabling Higher Photoelectrochemical Efficiency of TiO2 via Controlled Formation of Disordered Shell: Alternative to Hydrogenation Process

04.05.2016 | Vitaly Gurylev; Mrinalini mishra; Chung-Yi Su; Tsong-Pyng Perng, Chemical Communication, 2016

A simple one-step and low-temperature process was developed to form an amorphous overlayer on the crystalline TiO2 film by atomic layer deposition. This composite structure is beneficial for improved photoelectrochemical efficiency since the as-deposited amorphous layer showed unique properties ...

One-step growth of lanthanoid metal-organic framework (MOF) films under solvothermal conditions for temperature sensing

04.05.2016 | Xue Liu; Wen Tian Fu; Elisabeth Bouwman, Chemical Communication, 2016

A one-step direct solvothermal synthesis of an Ln metal-organic framework (MOF) film is reported. The LnHL (Ln=Tb and Gd) films that were deposited on a Gd2O3 subtrate are continuous and smooth. The Gd0.9Tb0.1HL film can be used as a ratiometric thermometer, showing good linear behaviour in the ...

Fractional Electron Number, Temperature, and Perturbations in Chemical Reactions

04.05.2016 | Ramon Alain Miranda-Quintana; Paul Ayers, Physical Chemistry Chemical Physics, 2016

We provide a perspective on the role of non-integer electron number in the density functional theory approach to chemical reactivity (conceptual DFT), emphasizing that it is important to not only treat reagents as open systems, but also as non-isolated systems, in contact with their surroundings. ...

Mild synthesis of {001} facets predominated Bi2O2CO3 clusters with outstanding simulated sunlight photocatalytic activities

04.05.2016 | Li-Min Yang; Guoying Zhang; Hai-Rong Wang; Xue Bai; Xing-Qi Shen; Jing-Wang Liu; Dongzhao Gao, CrystEngComm, 2016

Bi2O2CO3 clusters built up of ultrathin nanosheets with predominated {001} facets were facilely synthesized via a template-free hydrothermal strategy at a mild temperature of 60 °C. The Na2CO3 dosage and reaction temperature are confirmed to be key parameters to obtain the hydrolysis product of ...
