Star mesogens — Synthesis and structural characterization using 1D and 2D solution NMR techniques and mesophase characterization
17-10-2013 | A. Shanavas, T. Narasimhaswamy, B.V.N. Phani Kumar, A. Sultan Nasar, Canadian Journal of Chemistry, 2013
Utilisant des approches divergentes, on a réalisé des synthèses de nouveaux mésogènes en forme étoilée à base d'acide trimésique et des portions centrales portant des chaînes latérales symétriques se terminant par des groupes alcoxy. Les portions centrales et les chaînes latérales sont liées ...
Synthesis of CuO Nano/Micro-Crystals with Controlled Dimensionality and Morphology and Their Electrochemical Properties
19-06-2013 | Guanhua Lin; Wensheng Lu; Wenjie Dong, CrystEngComm, 2013
In this paper, two-dimensional (2D) CuO microsheets and three-dimensional (3D) flower-like hierarchical microstructures had been successfully fabricated by using a tree-type multi-amine head surfactant C18N3 in the aqueous solution. Morphology and dimensionality control of well-defined CuO ...
Selective aqueous phase oxidation of 5-hydroxymethylfurfural to 2,5-furandicarboxylic acid over Pt/C catalysts: influence of the base and effect of bismuth promotion.
19-06-2013 | Michèle Besson; Hicham Ait Rass; Nadine Essayem, Green Chemistry, 2013
5-Hydroxymethylfurfural (HMF) was quantitatively oxidized to 2,5-furandicarboxylic acid (FDCA) at 100°C under 40 bar air in moderately basic aqueous solution in the presence of active carbon supported platinum and bismuth-platinum catalysts. The transformation of HMF to FDCA proceeded via the ...
How deprotonation changes molecular self-assembly – an AFM study in liquid environment
19-06-2013 | Martin Schreiber; Michael Eckardt; Stefanie Klassen; Holger Adam; Martin Nalbach; Lukas Greifenstein; Felix Kling; M ..., Soft Matter, 2013
We study the influence of Alizarin Red S deprotonation on molecular self-assembly at the solid–liquid interface of the natural cleavage plane of calcite immersed in aqueous solution. To elucidate the adsorption details, we perform pH dependent high-resolution atomic force microscopy ...
Synthesis of Ag@SiO2 Hybrid Nanoparticles Templated by a Triton X-100)/1-hexanol/cyclohexane/H2O Water-in-Oil Microemulsion
19-06-2013 | Hang Lu; Huanfeng Ju; Qiao Yang; Ziran Li; Huaying Ren; Xia Xin; Guiying Xu, CrystEngComm, 2013
A water-in-oil microemulsion was prepared by using nonionic surfactant Triton X-100, 1-hexanol, cyclohexane and AgNO3 aqueous solution with a concentration of 0.2 molL-1. Successive addition of sodium borohydride (NaBH4), ammonium hydroxide (NH3·H2O) and tetraethyl orthosilicate (TEOS) to ...
Photoassisted synthesis of manganese oxide nanostructures using visible light at room temperature
19-06-2013 | Lavinia Balan; Camelia Matei Ghimbeu; Loïc Vidal; Cathie Vix-Guterl, Green Chemistry, 2013
A green chemistry approach was successfully used in this work to synthesize manganese oxide nanoparticles with different shapes and crystalline phases. This approach is based on the visible light irradiation (445 nm) at room temperature of an aqueous solution of a manganese(ii) salt in the ...
Crystallization of monohydrocalcite in silica-rich alkaline solution
19-06-2013 | Gan Zhang; José Manuel Delgado-López; Duane Choquesillo-Lazarte; Juan Manuel Garcia-Ruiz, CrystEngComm, 2013
Monohydrocalcite was crystallized in silica-rich alkaline solutions at room temperature using the counter diffusion method (CDM) in the absence of magnesium, by the reaction of calcium chloride and sodium carbonate. Field-emission scanning microscopy observations showed monohydrocalcite ...
Carbazole based hemicyanine dye for both “naked eye” and ‘NIR’ fluorescence detection of CN- in aqueous solution: from molecules to low cost devices (TLC plate sticks)
19-06-2013 | Shyamaprosad Goswami; Sima Paul; Abhishek Manna, Dalton Transactions, 2013
A hybrid carbazole hemicyanine dye (receptor CHD) was developed as a new visible and near infrared chemodosimeter type sensor with high ratiometric selectivity towards cyanide in presence of other anions in aqueous solution. The chemosensor also showed an excellent performance towards “dip ...
Solution-processable metal oxide semiconductors for thin-film transistor applications
19-06-2013 | Stuart R. Thomas; Pichaya Pattanasattayavong; Thomas D. Anthopoulos, Chemical Society Reviews, 2013
In this review, we discuss the merits of solution-processed metal oxide semiconductors and consider their application in thin-film transistors for large-area electronics.
Slow dynamics of water molecules in an aqueous solution of lithium chloride probed by neutron spin-echo
19-06-2013 | E. Mamontov; M. Ohl, Physical Chemistry Chemical Physics, 2013
Aqueous solutions of lithium chloride are uniquely similar to pure water in the parameters such as glass transition temperature, Tg, yet they could be supercooled without freezing down to below 200 K even in the bulk state. This provides advantageous opportunity to study low-temperature ...
