High efficiency TiO(2) photocatalyst in porous nanotubes were prepared by solvothermal alcoholysis of TiOSO(4) in the presence of carbon nanotube template.
A systematic study on the design of fulleropyrrolidine derivatives as the acceptor of photovoltaic cells has been carried out using poly(3-hexylthiophene) (P3HT) as the model base polymer. It was found that N-methoxyethoxyethyl-2-(2-methoxyphenyl)fulleropyrrolidine worked as a good acceptor partner with P3HT and a hig…
Inorganic–organic hybrid titanium phosphonate materials with a hierarchically-porous structure were synthesized by a mild solvent evaporation strategy using 1-hydroxyethylidene-1,1-diphosphonic acid as an organophosphorus coupling molecule. The preparations were accomplished with the use of triblock copolymers F127 an…
A liquisolid system has the ability to improve the dissolution properties of poorly water soluble drugs. Liquisolid compacts are flowing and compactable powdered forms of liquid medications. The aim of this study was to enhance the in vitro dissolution properties of the practically water insoluble loop diuretic furose…
A survey over X-ray absorption methods in homogeneous catalysis research is given with the example of the iron-catalyzed Michael addition reaction. A thorough investigation of the catalytic cycle was possible by combination of conventional X-ray absorption spectroscopy (XAS), resonant inelastic X-ray scattering (RIXS)…
New pseudo-trigonal planar supramolecular building blocks housing tri-capped trigonal prismatic [Cu(9)] clusters have been isolated from the facile reaction of Cu(II) salts with p-(t)But-calix[4]arene.
Two new mixed ligand complexes of cobalt(iii) containing ancillary biimidazole ligands, [Co(phen)(2)H(2)biim](ClO(4))(3).0.5(H(7)O(3))(ClO(4)) (1) and [Co(bpy)(2)H(2)biim](ClO(4))(3).3H(2)O (2) have been synthesized and characterized by various spectroscopic and electrochemical techniques. Both complexes and , have be…
Abstract The paper reviews the recent year publications concerning organic field-effect transistors (OFETs). A lot of works have been performed to help understanding the structural and electrical properties of materials used to construct OFETs. It has been established that in partially ordered systems, the charge tran…
In a situation which is far from ideal, many buffers have been found to be quite reactive, besides maintaining their stable pH values. On the basis of apparent transfer free energies (ΔG(tr)'), through solubility measurements the interactions of zwitterionic glycine peptides: glycine (Gly), diglycine (Gly(2)), triglyc…
We have developed a novel host material, 9,9′-(2-((4-phenyl-1,2,3-triazol-1-yl)methyl)biphenyl-4,4′-diyl)biscarbazole (CBP-TA), for realizing highly efficient blue phosphorescent OLEDs. The maximum external quantum efficiency of the OLED device developed using CBP-TA doped with a blue phosphorescent material was 30% g…
Carbon nanocages with a nanographene shell have been prepared by catalytic decomposition of p-xylene on a MgO supported Co and Mo catalyst in supercritical CO2 at a pressure of 10.34 MPa and temperatures ranging from 650 to 750 °C. The electrochemical performance of these carbon nanocages as anodes for lithium ion bat…
A fast and economical route based on microwave-assisted hydrothermal reaction has been developed to synthesize pancake-like Fe2(MoO4)3 microstructures. The phase and morphology of the products have been characterized by powder X-ray diffraction (XRD), energy dispersive spectrometry (EDS), selected area electron diffra…
In order to study the seasonal variations in the structure and dynamics of phytoplankton community of the Lake Baiyangdian in China, quantitative samples were collected in each season during 2005. A total of 152 taxa were identified by microscope, phytoplankton had an abundance ranging from 131.25 × 104 ind. L-1 to 74…
The formation of transient metal hydride(s) at the metallo-sulfur active sites of [FeFe]-hydrogenase is implicated in both hydrogen evolution and uptake reactions. Using a combination of time-resolved NMR, stopped-flow UV and stopped-flow IR, we have begun to unravel the mechanisms for protonation of synthetic electro…
The textile industry can experience a vast array of problems. Modelling represents a group of techniques that have been widely used to explore the nature of these problems, it can highlight the mechanisms involved and lead to predictions of the textile behaviour. This book provides an overview of how textile modelling…
In the present study total eight heavy metal resistant Pseudomonas sp were isolated from sewage of industrial effluents from waste water treatment plant of Paonta Sahib H.P. India, against chromium, copper, nickel, cadmium. All the isolates exhibited high resistance to heavy metals with minimum inhibitory concentratio…
A series of fluorinated metal–organic frameworks (F-MOFs) have been successfully synthesized under hydrothermal condition using 4,4′-(hexafluoroisopropylidene) bis(benzoic acid) (C17H10F6O4, H2hfbba) as a flexible dicarboxylate building block, Cu+2 and various heterocyclic co-ligands. These F-MOFs formulated as [Cu(hf…
Background: Switchgrass (Panicum virgatum L.) is being considered as a potential feedstock for bioethanol production and extensive research is ongoing to establish the optimum pretreatment conditions for switchgrass. Cellulose comprises the most abundant biopolymer in the biosphere and its crystalline/ultrastructure i…
This paper aims to define a minimum set of finite-element (FE) solutions to be used in the design and analysis of saturated permanent-magnet motors. The choice of the FE solutions belonging to this set is strictly associated with the classicald-qaxis theory, and it is described in terms of key points on the flux-magne…
Ammonia (NH3) sensors based on carbon/silicon (C/Si) heterojunctions are demonstrated at room temperature (RT). Upon exposure to NH3 molecules (0.2 ml l−1) at RT, the interface capacitance of C/Si junction increases dramatically, to about 230%. The results show that C/Si junctions have high NH3 gas sensitivity, rapid…
