Irradiation of the hyaline or fibrous cartilage excised from the body of a human cadaver with Er:YAG laser beam, single pulse with a dose of 1 J, produces a crater with a depth of approximately 500… (More)
Abstract Microstructure and optical properties of CeO 2 nanocrystallites (∼5 nm) supported on SiO 2 and subjected to heat treatment in hydrogen up to 1100 °C have been studied by high resolution… (More)
The sol–gel technique is a very flexible, relatively simple, and low-cost method to fabricate many different innovative photonic structures characterized by specific functionalities. During… (More)
Tb3+-doped Lu2O3 sintered ceramics were prepared in vacuum and in air. It was shown that the vacuum-sintered disks are able to store energy when irradiated with 300-nm or shorter photons. A small… (More)
Two series of Lu2O3:Eu nanocrystalline phosphors were prepared using either combustion procedure with urea fuel or the Pechini procedure. The dopant concentration varied in both series from 0.2 to… (More)
Abstract Using combustion synthesis and urea as a fuel, Lu 2 O 3 powders were prepared and their morphology defined with HRTEM measurements. The powders were sintered at 1700 °C for 5 h and the… (More)
Abstract Preparation and morphology of nanocrystalline and nanoporous ceramics composed of a network of alumina and zinc aluminate doped with Tb ions are reported. The pore size distributions are… (More)
For the first time nanoparticles of the title compound are prepared by a wet chemical process.
Neodymium-doped barium titanate (BaTiO3) nanocrystalline powders were prepared by the sol-gel method. Structure and average grain sizes were analysed by X-ray powder diffraction (XRD) measurements.… (More)
