we developed biofunctionalized nanoparticles with magnetic properties by immobalizing diethyle-neglycol (deg) on gd2o3, and pegilation of small particulate gadolinium oxide (spgo) with two me-thoxy-polyethyleneglycol-silane (mpeg-silane 550 and 2000 da) using a new supervised polyol route, described recently. in conjunction to the previous study to achieve a high quality synthesis and increase ...

Several oxide-GaAs heterostructures were fabricated using in situ multiple-chamber molecular beam epitaxy. The oxides include SiO2, MgO, and Ga2O3~Gd2O3!, all evaporated by an electron beam method. The SiO2 and Ga2O3~Gd2O3! films are amorphous while the MgO films are crystalline and part of the films are epitaxially grown on GaAs~100!. Among these heterostructures, the Ga2O3~Gd2O3!–GaAs shows a...

Gadolinium oxide (Gd2O3) nanoparticles were prepared via the reaction of gadolinium nitrate hexahydrate (Gd (NO3)3·6H2O) and ethylamine (C2H5NH2), their surface morphology, particle size, properties examined by using scanning electron microscopy, X-ray diffraction (XRD), Raman spectroscopy, Fourier transform infrared (FT-IR) ultraviolet visible (UV-vis) spectroscopy. The Gd2O3 used as photocata...

We report the formation of silicide by annealing a SiOx surface, with low coverage Eu doped Gd2O3 nanoparticles. The temperature required for removal native oxide from Si substrate decreases close to 200 °C in presence X-ray photoemission electron microscopy, low-energy microscopy and mirror are used monitor removal. Fragmentation nanoparticles is observed, layer gradually removed. migrates cle...

This paper presents a simple and effective oil-water interfacial self-assembly strategy to fabricate monolayer and bilayer nanofilms of densely packed Gd2O3:0.05X(3+) (X = Eu, Tb) nanorods with characteristic luminescence properties. In this process, Gd2O3:0.05X(3+) (X = Eu, Tb) nanotubes synthesized by a hydrothermal method are dispersed in deionized water; then, a certain amount of n-hexane i...

In this study, Gd2O3 nanocrystal (Gd2O3-NC) memories with nanostructure tunneling layers are fabricated to examine their performance. A higher programming speed for Gd2O3-NC memories with nanostructure tunneling layers is obtained when compared with that of memories using a single tunneling layer. A longer data retention (< 15% charge loss after 104 s) is also observed. This is due to the incre...

As the utility of magnetic resonance imaging (MRI) broadens, the importance of having specific and efficient contrast agents increases and in recent time there has been a huge development in the fields of molecular imaging and intracellular markers. Previous studies have shown that gadolinium oxide (Gd(2)O(3)) nanoparticles generate higher relaxivity than currently available Gd chelates: In add...
