In situ TOPO decomposition was accomplished by applying a vacuum at elevated temperatures to a precursor solution in the presence of oxygen, leading TOPO to oxidize to di-n-octylphosphinic acid (DOPA) and octylphosphonic...
Porous sol-gel silica films are prepared using different PMMA latex nanoparticles, 30-80 nm in diameter, as sacrificial templates. By changing the size and the content of the latex particles in the deposited silica sol, ...
High quality silica substrates were functionalized with a covalent 4-ClCH2C6H4SiCl3 monolayer. To these, a calix[5]arene bearing a 12-aminododecyl moiety at the lower rim was then covalently bonded, producing a new calix...
A new, highly efficient green oxyfluoride phosphor family Sr2.975-xBaxCe0.025AlO4F (SBAF:Ce3+) has been developed as a component of solid state white light emitting diodes (LED). The phosphor emits with a maximum at 502 ...
Ru thin films were grown on Au, Pt, TiN, TiO2, and SiO2 substrates by atomic layer deposition using 2,4-(dimethylpentadienyl)(ethylcyclopentadienyl)Ru (DER) dissolved in ethylcyclohexane at a concentration of 0.2 M as th...
Nanocrystalline Li4Ti5O12 (LTO) crystallizing in cubic spinel-phase has been synthesized by single-step-solution-combustion method in less than one minute. LTO particles thus synthesized are flaky and highly porous in na...
Poly(3,4-ethylenedioxythiophene) (PEDOT) thin films were obtained through oxidative chemical vapor deposition (oCVD) by using a new oxidant-bromine. The use of bromine eliminates any post processing rinsing step required...
New organic-inorganic hybrid materials that combine a bent pi-conjugated aromatic core with one linear or branched carbosilane unit have been synthesized and investigated, with respect to their self-assembly in liquid cr...
The substitution of zinc for iron in YBaFe4O7 has allowed the oxide series YBaFe4-xZnxO7, with 0.40 <= x <= 1.50, belonging to the "114" structural family to be synthesized. These oxides crystallize in the hexagonal symm...
In this study, a high-temperature reduction method is developed to prepare iron silicide nanoparticles in solution phase. The synthesis applies a reaction of silicon tetrachloride with iron pentacarbonyl in the presence ...
The temperature-programmed reaction of Co3Mo3N under H-2/Ar results in a new nitride with composition Co6Mo6N. Powder neutron diffraction (PND) studies have confirmed unequivocally that the compound possesses the eta-12 ...
Because of the Jahn Teller effect and low tolerance factor, the only reported method to obtain ErMnO3 materials with orthorhombic perovskite structure is to apply a high external pressure (on the order of GPa) at high te...
A new route of in situ formation and stabilization of ultrathin, needle-like manganese dioxide nanoparticles (MnO2NP) in aqueous solution by using spherical polyelectrolyte brush particles (SPB) is presented. The SPB tha...
Surface-modified hydrogels with a polyion complex composed of poly(vinylamine) (PVAm) and poly(acrylic acid) (PAAc) were prepared in order to control the release of drug molecules without a volume change of the hydrogel....
We demonstrate that H-1 spin diffusion NMR is a valuable method to estimate the domain size distribution in bulk heterojunction (BHJ) active layers composed of poly-3-hexylthiophene (P3HT) and phenyl-C-61-butyric acid me...
The surface and interface enthalpies of cubic stabilized zirconia solid solutions containing 8, 10, and 12 mol % Y2O3 were determined by a combination of calorimetric, morphological, and structural analyses techniques. N...
