Characterization of Titanium Alkoxide- Based Sol-Gel Systems and their Behavior in Icephobic Coatings
… The melt-point depresssant complex consists of a titanium alkoxide-based sol-gel system designed to facilitate the slow-release of tripropylene glycol (TPG) and glycerol to the coating surface. The presence of these compounds is necessary for effective prevention of the nucleation and adhesion of …

Reactive amphiphilic block copolymers for the preparation of hybrid inorganic/organic materials
… are used for patterning of highly ordered titanium dioxide nanoparticles on a silicon wafer. The amphiphilic block copolymers were synthesized by sequential anionic polymerisation of the corresponding monomers in benzene with the sec-butyl lithium/phosphazene base initiating system to …

Synthesis of polymers and copolymers of lactide through titanium initators
… polymers of lactide through non-toxic titanium alkoxide nitiators. The research objectives focused on the preparation of polylactides in both solvent and solventless media, to produce materials with a wide range of molecular weights. The polylactides were fully characterised using gel …

Fabrication of ceramic layer-by-layer infrared wavelength photonic band gap crystals
… The infilling materials studied include titanium alkoxide precursors and aqueous suspensions of nanosize titania particles (slurries). Various infilling materials were synthesized to determine viscosities, effects on drying and firing shrinkages, effects on film surface roughness, and …

The sol-gel synthesis of anti-stokes luminescent glass materials
… was found that glass ceramics also formed when a titanium alkoxide is incorporated with fluoride ions during the sol-gel synthesis of these lattices. In these cases it was shown that TiO2 in the form of anatase or rutile crystallites can be grown in the glass matrix. Moreover the phase of TiCb …

Nichtwässrige Synthese und Bildungsmechanismus von Übergangsmetalloxid-Nanopartikeln = Nonaqueous synthesis of transition-metal oxide nanoparticles and their formation mechanism
… by solvothermal reaction of metallic barium and titanium isopropoxide in organic solvents. Phase-pure, highly crystalline particles about 6 nm in size resulted in benzyl alcohol, whereas larger particles could be obtained in ketones such as acetone or acetophenone. In benzyl alcohol, a novel …

One-dimensional hybrid nanomaterials based on cylindrical polymer brushes
… a kind of titania-CPB hybrid nanowires. The titanium alkoxide precursor was introduced into the CPB via a transalcoholysis reaction between Ti(OC4H9)4 and the PHEMA block. The titania-CPB hybrid nanowires were used to generate anatase titania nanowires via pyrolysis at 550 °C. In general, all …

Microstructure evolution and crystallisation kinetics of pure and isovalently substituted lead titanate thin films derived by chemical solution deposition
… the powder lead(II) acetate and a liquid titanium alkoxide reacted to an ester and, more importantly, a compound that comprised a Pb O Ti linkage and thus constituted the basic element of the final PbTiO3 film. Besides the formation of heteroleptic alkoxides by alkoxy group exchange with …
