ZnO nanorod/porous silicon nanowire hybrid structures as highly-sensitive NO2 gas sensors at room temperature

09.02.2016 | Jiecui Liao; Zhengcao Li; Guojing Wang; Chienhua Chen; Shasha Lv; Mingyang Li, Physical Chemistry Chemical Physics, 2016

ZnO nanorod/porous silicon nanowire (ZnO/PSiNW) hybrids with three different structures as highly sensitive NO2 gas sensors were obtained. PSiNWs were first synthesized by metal-assisted chemical etching, and then seeded in three different ways. After that ZnO nanorods were grown on the seeded ...


Unusual temperature dependence of elastic constants of an ambient-temperature discotic nematic liquid crystal

09.02.2016 | D Venkata Dasari; Giorgio Mirri; P Kouwer; Rasmita Sahoo; Igor Musevic; Surajit Dhara, Soft Matter, 2016

We report first experimental studies on the temperature dependence of viscoelastic properties of a room temperature discotic nematic liquid crystal. The splay elastic constant is greater than the bend elastic constant and both show unusual temperature and order parameter dependence. The ...


Control of interpenetration in a microporous metal–organic framework for significantly enhanced C2H2/CO2 separation at room temperature

09.02.2016 | Ganggang Chang; Bin Li; Hailong Wang; Tongliang Hu; Zongbi Bao; Banglin Chen, Chemical Communication, 2016

A novel non-interpenetrated three-dimensional porous metal–organic framework UTSA-68 has been controllably synthesized by altering the reaction conditions. The resulting UTSA-68a shows a notably higher porosity and adsorption selectivity (3.5–5) for C2H2/CO2 separation compared to that of doubly ...


Chemical vapor generation from an ionic liquid using a solid reductant: determination of Hg, As and Sb by atomic fluorescence spectrometry

09.02.2016 | Xiaodong Wen; Ying Gao; Peng Wu; Zhiqiang Tan; Chengbin Zheng; Xiandeng Hou, Journal of Analytical Atomic Spectrometry, 2016

Generation of volatile hydrides and elemental mercury was accomplished in non-aqueous media by using a solid reductant of lithium aluminium tetrahydride (LiAlH4), stannous chloride dehydrate (SnCl2) or tetrahydroborate (THB) as a derivation reagent. A room temperature ionic liquid (RTIL) was used ...


Intramolecular structure and energetics in supercooled water down to 255 K

09.02.2016 | Felix Lehmkühler; Yury Forov; Thomas Buening; Christoph Johannes Sahle; Ingo Steinke; Karin Julius; Thomas Buslaps; ..., Physical Chemistry Chemical Physics, 2016

We studied the structure and energetics of supercooled water by means of X-ray Raman and Compton scattering. At supercooled conditions down to 255 K, the oxygen K-edge measured by X-ray Raman scattering suggests an increase of tetrahedral order similar to the conventional temperature effect ...


A2SbB3O8(A = Na, K, Rb) and [small beta]-RbSbB2O6: Two Types of Alkali Boroantimonates with 3D Anionic Architectures Composed of SbO6 Octahedra and Borate Groups

09.02.2016 | Dong Yan; Chun-Li Hu; Jianggao Mao, CrystEngComm, 2016

Four new alkali metal boroantimonates, namely, A2SbB3O8 (A = Na, K, Rb) and β-RbSbB2O6, have been synthesized by high temperature solid-state reactions. Isostructural A2SbB3O8 (A = Na, K, Rb) crystallize in monoclinic space group P21/c, with structures featuring a novel 3D anionic framework ...


Nonstoichiometry of tris(8-hydroxyquinoline) aluminium. Is it possible?

09.02.2016 | Igor Christophorovich Avetissov; Alina Akkuzina; Romen Avetisov; Andrew Khomyakov; Rasim Saifutyarov, CrystEngComm, 2016

The dependence of the 8-hydroxyquinoline (8-Hq) vapor pressure on temperature lgP8-Hq [torr] = 8.4249 – 2963.5/T was experimentally determined in the 386-482 K temperature range using Burdon manometer technique. Tris(8-hydroxyquinoline) aluminum (α-Alq3) crystals were synthesized under 8-Hq ...


Angle isomerism, as exemplified in a five coordinate, dimeric copper(II) Schiff base complex. Observation of Ostwald ripening

09.02.2016 | Shanti G Patra; Nirmal K Shee; Michael G B Drew; Dipankar Datta, New Journal of Chemistry, 2016

The 1:1 condensate of benzil and 2-hydrazinopyridine is the ligand (LH; H: a dissociable proton) here. Its reaction with CuCl2.2H2O in methanol at room temperature in equimolar proportion affords a mixture of two types of dark green (with metallic luster) single crystals  hexagonal (1a) and ...


Antibacterial and antioxidant bio-based networks derived from eugenol using photo-activated thiol-ene reaction

07.02.2016 | Author(s): Tina Modjinou, Davy-Louis Versace, Samir Abbad-Andallousi, Noureddine Bousserrhine, Pierre Dubo ..., Reactive and Functional Polymers, 2016

Publication date: Available online 5 February 2016 Source:Reactive and Functional Polymers Author(s): Tina Modjinou, Davy-Louis Versace, Samir Abbad-Andallousi, Noureddine Bousserrhine, Pierre Dubot, Valérie Langlois, Estelle Renard Bio-based networks derived from eugenol and ...


Non-symmetrical furan-amidines as novel leads for the treatment of cancer and malaria

07.02.2016 | Author(s): Soraya Alnabulsi, Elham Santina, Ilaria Russo, Buthaina Hussein, Manikandan Kadirvel, Amy Cha ..., European Journal of Medicinal Chemistry, 2016

Publication date: 23 March 2016 Source:European Journal of Medicinal Chemistry, Volume 111 Author(s): Soraya Alnabulsi, Elham Santina, Ilaria Russo, Buthaina Hussein, Manikandan Kadirvel, Amy Chadwick, Elena V. Bichenkova, Richard A. Bryce, Karen Nolan, Constantinos ...
