Embedding CoPt magnetic nanoparticles within a phosphate glass matrix
(2020-12-25)
Glasses are materials with highly flexible compositions and high chemical and physical durability. These characteristics make them suitable materials for hosting nanoparticles for different purposes. Hybrid glasses containing ...
Structural and magnetic properties of Fe76P5(Si0.3B0.5C0.2)19 amorphous alloy
(Elsevier Science, 2012-09)
Recently, bulk amorphous alloys were produced in the Fe–B–Si–P–C system with high glass forming ability, excellent magnetic properties and the advantage of containing no expensive glass-forming elements, such as Ga, Y, Cr ...
Influence of volcanic glass on the magnetic signal of different paleosols in Córdoba, Argentina
(Springer, 2017-04)
This contribution comprises geological and magnetic results obtained in loess and paleosols profiles outcropped in the Pampean plain (Argentina). The sedimentary sequence exposed in Córdoba province is represented by four ...
Phosphate glasses containing monodisperse Fe3−δO4@SiO2 stellate nanoparticles obtained by melt-quenching process
(2020-06-01)
The challenge to obtain stable glasses containing monodisperse magnetic nanoparticles with controlled size and shape is an exciting and almost unexplored field of research. Such new materials can be used in magneto-photonics ...
Synthesis and characterization of glass-ceramic microspheres for thermotherapy
(ELSEVIER SCIENCE BV, 2010)
Glass microspheres containing radionuclides are used to treat liver cancer. A promising alternative therapy is being developed based on the magnetic hyperthermia which is related to the heat supplied by a magnetic material ...
Magnetic Resonance and Conductivity Study of Lead-Cadmium Fluorosilicate Glasses and Glass-Ceramics
(2018-03-22)
The fluorine motional dynamics in fluorosilicate glasses and glass-ceramics of the SiO2-PbF2-CdF2 system was investigated by complex impedance spectroscopy and 19F nuclear magnetic resonance (NMR) spectroscopy, and the ...
Influence of metallic nanoparticles on electric-dipole and magnetic-dipole transitions of Eu(3+) doped germanate glasses
(AMER INST PHYSICS, 2010)
Luminescence properties of Eu(3+) doped germanate glasses containing either silver or gold nanoparticles (NPs) were investigated for excitation at 405 nm. Enhanced emissions and luminescence quenching of the Eu(3+) transitions ...
Mechanism of the formation and properties of antimony polyphosphate
(2005-07-01)
Formation of antimony polyphosphate using Sb2O3 and/or (NH4)2HPO4 and NH4H 2PO4 as starting materials has been simulated by thermal analysis technique. The elimination of water and ammonia molecules induced by heating leads ...
