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 ...
Solution-cathode glow discharge – optical emission spectrometry using a compact spectrograph
22-05-2013 | Todd A. Doroski; Allison M. King; Michael P. Fritz; Michael R. Webb, Journal of Analytical Atomic Spectrometry, 2013
A solution-cathode glow discharge is coupled to a compact spectrograph. Such a coupling results in a small, potentially portable instrument that can simultaneously detect a range of metals by optical emission spectrometry. Detection limits were calculated for Ag (1 ppb), Cd (2 ppb), Cu (8 ...
Efficient panchromatic inorganic–organic heterojunction solar cells with consecutive charge transport tunnels in hole transport material
22-05-2013 | Haiwei Chen; Xu Pan; Weiqing Liu; Molang Cai; Dongxing Kou; Zhipeng Huo; Xiaqin Fang; Songyuan Dai, Chemical Communication, 2013
A simple solution-processing method was employed to fabricate panchromatic mp-TiO2/CH3NH3PbI3/P3HT–MWNT/Au solar cells. MWNTs in a P3HT–MWNT composite acted as efficient nanostructured charge transport tunnels and induce crystallization of P3HT, hence significantly enhancing the conductivity ...
Highly Enhanced Energy Conversion from the Streaming Current by Polymer Addition
22-05-2013 | Trieu Nguyen; Yanbo Xie; Lennart J. de Vreede; Albert van den Berg; Jan C.T. Eijkel, Lab on a Chip, 2013
In this contribution, we present for the first time the experimental results of energy conversion from the streaming current when polymer is added to the working solution. We added polyacrylic acid (PAA) in concentrations of 200 ppm to 4000 ppm to a KCl solution. By introducing PAA, the input ...
Carbohydrate and Lignin are Simultaneously Solubilized from Unpretreated Switchgrass by Microbial Action at High Temperature
22-05-2013 | Ira Kataeva; Marcus B Foston; Sung-Jae Yang; Sivakumar Pattathil; Ajaya K Biswal; Farris L Poole; Mirko Basen; Amand ..., Energy & Environmental Science, 2013
The three major components of plant biomass, cellulose, hemicellulose and lignin, are highly recalcitrant and deconstruction involves thermal and chemical pretreatment. Microbial conversion is a possible solution, but few anaerobic microbes utilize both cellulose and hemicellulose and none ...
Radially aligned microchannels prepared from ordered arrays of cracks on colloidal films
22-05-2013 | Hongmin Ma; Picheng Gao; Dawei Fan; Guobao Li; Dan Wu; Bin Du; Qin Wei, Physical Chemistry Chemical Physics, 2013
Arrayed microchannels with dimensions of tens to hundreds of micrometres show great potential for application in microfluidics, microreactor devices and other areas. In this work, we report the formation of ordered arrays of cracks on solution-cast colloidal films, and the preparation of ...
A Triphenylamine-capped Solution-Processable Wholly Aromatic Organic Molecule with Electrochemical Stability and Its Potential Application in Photovoltaic Devices
22-05-2013 | Zhiming Wang; Xiaohui Song; Lingling Ma; Ying Feng; Cheng Gu; Xiaojuan Zhang; Ping Lu; Yuguang Ma, New Journal of Chemistry, 2013
A triphenylamine-capped solution-processable wholly aromatic conjugated molecule, TPA-TVBP, was designed and synthesized. It exhibited a high thermodynamic stability and good film forming ability as expected, originating from the absent of alkyl and alkoxyl moieties. The triphenylamine cap ...
Synthesis and electrocatalytic activity of highly porous hollow palladium nanoshells for oxygen reduction in alkaline solution
22-05-2013 | Yun-Bin Cho; Ji Eon Kim; Jun Ho Shim; Chongmok Lee; Youngmi Lee, Physical Chemistry Chemical Physics, 2013
A series of hollow Pd nanoshells are prepared by employing Co nanoparticles as sacrificial templates with different concentrations of Pd precursor (1, 6, 12, 20, and 40 mM K2PdCl4), denoted as hPd-X (X: concentration of K2PdCl4 in mM unit). The synthesized hPd series are tested as a cathodic ...
Heterometallic Co(II)-Ru2(II,III) Carbonates: From Discrete Ionic Crystals to Three-Dimentional Network
22-05-2013 | Bin Liu, CrystEngComm, 2013
An investigation of the reaction conditions influence on the self-assembling Ru2(CO3)43- paddle-wheel precursors and Co2+ ions in aqueous solution has resulted in a series of Co(II)-Ru2(II,III) hetero-metallic complexes with different composition and dimensionality, namely ...
Synthesis and Photoluminescence Properties of Polybenzoxazoles Containing Perylenebisimide Functionalized Graphene Nanosheets via Stacking Interactions
22-05-2013 | Yong Chen; Jun Qian; Xiaoyun Liu; Qixin Zhuang; Zhewen Han, New Journal of Chemistry, 2013
The stable acidic dispersion of reduced graphene oxide (RGO) is prepared by non-covalent functionalization method using perylenebisimide modified fluorinated poly(hydroxyamide) (PTCDA-6FPHA). Then a series of RGO/polybenzoxazoles (PBO) composites were prepared by solution blending method in ...
