Fe-Doped Sol-Gel Glasses and Glass-Ceramics for Magnetic Hyperthermia
This work deals with the synthesis and characterization of novel Fe-containing sol-gel materials obtained by modifying the composition of a binary SiO₂-CaO parent glass with the addition of Fe₂O₃. The effect of different processing conditions (calcination in air vs. argon flowing) on the formation of magnetic crystalline phases was investigated. The produced materials were analyzed from thermal...
متن کاملTransparent Glass-Ceramics Produced by Sol-Gel: A Suitable Alternative for Photonic Materials
Transparent glass-ceramics have shown interesting optical properties for several photonic applications. In particular, compositions based on oxide glass matrices with fluoride crystals embedded inside, known as oxyfluoride glass-ceramics, have gained increasing interest in the last few decades. Melt-quenching is still the most used method to prepare these materials but sol-gel has been indicate...
متن کاملPhycobiliproteins Encapsulated in Sol-Gel Glass
Light transducing phycobiliproteins are encapsulated in optically transparent sol-gel matrices. Absorption and fluorescence spectroscopies are used to characterize the effect of the sol-gel encapsulation on the conformation and aggregation states of the three major phycobiliproteins present in phycobilisomes: phycoerythrin, phycocyanin, and allophycocyanin. It is found that the effects of sol-g...
متن کاملSynthesis, phase transformation and dielectric properties of sol–gel derived Bi2Ti2O7 ceramics
Sol–gel derived Bi2Ti2O7 ceramic powders have been prepared from methoxyethoxides of bismuth and titanium (molar ratio of Ti/Bi = 1.23 and water/alkoxides= 1.31). The Bi2Ti2O7 phase was stable at a low temperature (700 ◦C), but it then transformed into mixed phases of Bi4Ti3O12 and Bi2Ti4O11 at 850–1150 ◦C. The single phase of Bi2Ti2O7 reoccurred at 1200 ◦C. Dielectric properties and ferroelect...
متن کاملSynthesis and Characterization of Nanocomposite Films with a Titania Glass Matrix by the Sol±gel Route
Films of thickness 3 mm containing nanosized metal particles of iron, nickel and copper respectively were grown on a Corning glass slide using a sol-gel technique. The particle sizes had values in the range 6.8 to 20.1 nm. Optical absorption characteristics of different specimens were studied over the wavelength range 230 to 830 nm. An absorption maximum was observed at wavelength varying from ...
