Cyclometallated iridium complexes comprised of two terdentate cyclometallating ligands, of the form [Ir(Ninsertion markCinsertion markN)(Ninsertion markNinsertion markC)](+), have been explored for the preparation of multimetallic systems by palladium-catalysed cross-coupling reactions. An Ninsertion markNinsertion ma…
The complexes and contain [M(bipy)(3)](2+) chromophores with a pendant aza-18-crown-6 macrocycle for binding of lanthanide(iii) ions. The photophysical properties of the adducts . and ., prepared by addition of excess Ln(NO(3))(3) (Ln = Nd, Yb) to solutions of and in MeCN, were examined using time-resolved and steady-…
In this paper we report on dye structure–optical property correlations for a range of near-infrared emitting (NIR, 650–900 nm) fluorescent dyes in a 9–14 nm diameter core-shell silica particle architecture (C dots), including Cy5, Alexa Fluor 700, DY730, Alexa Fluor 750, and DY780. For each dye an apparent per-dye enh…
In vitro studies were carried out to test the antifungal activity of 5 plant extracts; Cinnamomum zeylanicum (Cinnamon), Cymbopogon proximus (Halfa barr), Laurus nobilis (Laurel), Persea americana (Avocado) and Zingiber officinale (Ginger) performed with either cold distilled water (CDW) or boiling (BDW) on two pathog…
Angle-resolved photoemission spectroscopy (ARPES) is a powerful experimental technique for directly probing electron dynamics in solids. The energy versus momentum dispersion relations and the associated spectral broadenings measured by ARPES provide a wealth of information on quantum many-body interaction effects. In…
One of the most known intelligent material is nitinol, which offers many functional advantages over conventional implantable alloys. Applications of SMA to the biomedical field have been successful because of their functional qualities, enhancing both the possibility and the execution of less invasive surgeries. The b…
A series of mesostructured H3PW12O40-silica materials were developed by using a single step co-condensation technique in the presence of nonionic oligomeric surfactant, C18H37(OCH2CH2)10OH (C18EO10, Brij76). By tuning the composition ratios of the starting precursors (mainly the molar ratios of water to the other mate…
Ammonia borane (NH(3)BH(3), AB) is an intriguing molecular crystal with an extremely high hydrogen capacity and moderate thermal stability. In the present study, we show a simple but effective approach for destabilizing AB for promoted hydrogen release at moderate temperatures. It is found that mechanically milling wi…
Chemical oxidation of poly(enetetramine)s was demonstrated as a new synthetic route to prepare conjugated polyelectrolytes.
We report on an approach to obtain anodic self-organized TiO 2 nanotube layers with a significantly improved tube morphology. Before the anodic tube growth, a rutile layer is formed on the Ti substrate by high temperature oxidation in air. This layer protects the tube tops during anodization against chemical etching i…
Polymer nanocomposites (PNCs) often exhibit excellent mechanical, thermal, electrical and optical properties, because they combine the performances of both polymers and inorganic or organic nanoparticles. Recently, computer modeling and simulation are playing an important role in exploring the reinforcement mechanism…
Size-controlled atomic-level Pd-Au alloy nanoparticles have been synthesized with a wide range of atomic ratios by a facile method using H2 gas, and their controllable hydrogen-absorption properties have been studied from hydrogen pressure-composition isotherms and solid-state 2H NMR spectra.
We report the spectrum of ocular toxicity following accidental inoculation of latex of Calotropis procera (Sodom apple) in 29 eyes between January 2003 and December 2006. All patients presented with sudden painless dimness of vision with photophobia. Twenty-five (86%) patients had initial visual acuity of less than 20…
Intrinsically photochromic ionic liquids can be prepared by simple combination of methyl orange, a well-known example of a photochromic azobenzene derivative, and the appropriate organic cations. These novel compounds are light responsive and maintain the properties peculiar to ionic liquids, a win-win situation.
An efficient and chemoselective liposome surface glyco-functionalization method has been developed based on Staudinger ligation, in which the carbohydrate derivative carrying an azide spacer is conjugated onto the surface of preformed liposomes bearing a terminal triphosphine in PBS buffer (pH 7.4) at room temperature.
Novel ultra-thin ZnSnO(3) nanowire architectures are prepared through a molecule template route; the products show a strong structure-induced enhancement of photocatalytic performance.
The use of shape memory alloy (SMA) components in passive structural control devices was repeatedly proposed in the last decade by several research groups. Among these proposals, an efficient coupling of SMA bars with a sliding system was recently introduced by the authors. It was studied at a prototype level to imple…
The polymerizable complex (PC) method was developed to prepare copper-based high-Tc superconducting oxides with improved superconducting properties, phosphor materials with excellent emission intensities and water-splitting photocatalysts with higher activities. The PC method is based on the formation of metal complex…
Dynamic processes of molecular self-assembly from two surfactant-like peptides A6K and A9K have been investigated by combining AFM and TEM measurements with SANS measurements. Aggregated peptide stacks were formed during the first hour of solution preparation, followed by their assembly into short nanofibrillar segmen…
Anisotropic particles adsorbed at a water-air interface are known to aggregate due to capillary interactions. We show that the packing configuration of a pair of prolate ellipsoids critically depends on their relative size and/or aspect ratio mismatch. While identical particles simply pack side-by-side, particles of s…
