We propose a simple method to prepare lipid nanotubes, which can be used to transport biological molecules. By applying shear stress to surface-immobilized liposomes on a solid substrate, we obtained long lipid nanotubes arranged in a well-controlled direction.
4 Abstract: Citrus medica Linn. (Rutaceae) known as Gajanimbe and is used as a folk medicine for the treatment of gastric ulcers. The present study was planned to evaluate the antiulcer activity of aqueous extract of the fruits against ethanol-induced ulcers in rats. The extract was subjected to phytochemical screenin…
Correction for 'Magnetic properties of the seven-coordinated nanoporous framework material Co(bpy)1.5(NO3)2 (bpy = 4,4'-bipyridine)' by Elena Bartolomé et al., Dalton Trans., 2012, 41, 10382-10389.
A facile PDMS-glass hybrid microfluidic device is developed for generating uniform submicrometer-scale double emulsion droplets with unprecedented simplicity and controllability. Compared with planar flow-focusing geometries, our three-dimensional flow-focusing geometry is advantageous for stably producing femto- to a…
We studied biomembrane fluctuations by calculating the instantaneous shape of model membranes adhered to micro-patterned substrates, using micro-interferometry. The model consisted of partially adherent giant unilamellar vesicles (GUVs) which were osmotically deflated. Adhesion was effected via the specific ligand–rec…
Ordered mesoporous NaTaO3 thin films with both 3D honeycomb and nanopillar-like structures were successfully produced through sol–gel templating using a novel amphiphilic diblock copolymer, PIB53-b-PEO45, as the structure-directing agent. These nanocrystalline materials not only exhibit enhanced UV-light photocatalyti…
UVA irradiation of glass mounted dye-sensitized solar cells without UV filtration causes failure within 400 hours of light exposure. The failure mode is shown to relate to consumption of I 3 − , which is directly related to TiO2 photo-catalysis. The onset of failure is easily determined from electrochemical impedance…
The modification of the poly(dimethylsiloxane) (PDMS) surface for improved wettability and biocompatibility has been a hot topic for its biological applications. We report here a facile biocompatible approach for PDMS modification by L-3,4-dihydroxyphenylalanine (L-Dopa) which renders the change of the PDMS surface fr…
Magnetic nanoparticles have been enjoying great importance and wide scale applications during the last two decades due to their specific characteristics and applications. Iron oxide magnetic nanoparticles with appropriate surface chemistry have been implied in numerous applications such as biomedicine and cancer thera…
A low-cost, ultra-thin, transparency and high-quality zinc oxide (ZnO) film was successfully demonstrated as the carrier transporting and semiconducting layer for thin-film transistor (TFT) devices. The ZnO ultra-thin film with 3.7 nm in thickness was spin-coated from zinc acetate sol-gel solution under electroless co…
The switching mechanism in carbon-based resistive-switching random access memory is modelled using a percolation approach built on the low-temperature transition between phases sp(3) (diamond-like and high-resistive state) and sp(2) (graphite-like and low-resistive state) for a matrix of carbon clusters in a diamond-l…
A metal-organic framework, Cu(3)(BTC)(2), was synthesized and applied as an electro-responsive electrorheological material dispersed in insulating oil. Powder of crystalline Cu(3)(BTC)(2) exhibited excellent chain-like structures and controllable rheological properties in an applied electric field.
Small-angle neutron scattering (SANS) is uniquely qualified to study the structure of proteins in liquid and solid phases that are relevant to food science and biotechnological applications. We have used SANS to study a model protein, lysozyme, in both the liquid and water ice phases to determine its gross-structure,…
Reaction of tris(5-amino-2-ethoxy-3-isopropylphenyl)methane and pyridine-2,6-dicarbonyl-dichloride affords a multi-dentate cryptand in 48% yield. Metallation with iron(III) chloride results in a substantial conformational change of this ligand to give a trianionic triiron(III) complex. Ferric cations line the peripher…
Nanoparticle suspensions represent a promising route toward low cost, large area solution deposition of functional thin films for applications in energy conversion, flexible electronics, and sensors. However, parameters such size, stoichiometry, and electronic properties must be controlled to achieve best results for…
In this paper we present the results of empirical potential and density functional theory (DFT) studies of models of interfaces between amorphous silicon (a-Si) or hydrogenated amorphous Si (a-Si:H) and crystalline Si (c-Si) on three unreconstructed silicon surfaces, namely (100), (110) and (111). In preparing models…
Tetraphenylethene (TPE) nanoparticles have been easily obtained by one-step vacuum sublimation the TPE powder. The TPE molecules crystallize themselves in room temperature which is probably due to their extremely low glass transition temperature. The as-deposited TPE nanoparticles scatter light effectively. By employi…
Electrical properties of p-NiO films fabricated by RF magnetron sputtering were studied for hydrogen sensor applications. A response of sheet resistance to hydrogen concentration in air has been measured at elevated temperature. Significant changes in sheet resistance of NiO films were observed even for H2 concentrati…
The synthesis and gas-sensing properties of ZnO particles from an ionic liquid precursor benzyltrimethylammonium hydroxide (BTMAH) is studied. The BTMAH, acting as reactant precursor and solvent, is demonstrated to be effective for synthesis of ZnO particles with controlled morphologies. The effect of the water and zi…
The in-plane residual stress in thin films greatly affects their properties and functionality as well as the substrate bending, and hence is an important factor to be controlled. In order to obtain general knowledge on the development of residual stress in sol-gel-derived oxide thin films, the in-plane residual stress…
