Ion-Exchange in Glass-Ceramics
In the past few years, ion-exchange (IOX) in glasses has found a renewed interest with a lot of new development and research in industrial and academic labs and the commercialization of materials with outstanding mechanical properties. These glasses are now widely used in many electronic devices, including hand-held displays and tablets. The exchange is generally conducted in a bath of molten s...
متن کاملIon Exchange in Glass – The Changes of Glass Refraction
The phenomenon of ion exchange in glasses in the practical application has been known since the Middle Ages when it was used for coloring glass. However, the application of this phenomenon for the production of changes in the glass refraction associates with the waveguide technology. The development of this technology has started in the second half of the 20th century and was dictated by the hu...
متن کاملYtterbium-Doped Glass Waveguide Laser Fabricated by Ion Exchange
A ytterbium-doped, glass, channel waveguide laser, fabricated by ion exchange, is reported. The 2.2-cm long device, using broad-band 4% output couplers, lased in the vicinity from 1020 to 1030 nm when pumped by a Ti : sapphire laser operating at 910 nm. A lasing threshold of 50 mW (launched pump) and a slope efficiency of 5% were measured. Device parameters, including fluorescence lifetimes, em...
متن کاملPorous glass electroosmotic pumps: theory.
This paper presents an analytical study of electroosmotic (EO) pumps with porous pumping structures. We have developed an analytical model to solve for electroosmotic flow rate, pump current, and thermodynamic efficiency as a function of pump pressure load for porous-structure EO pumps. The model uses a symmetric electrolyte approximation valid for the high-zeta-potential regime and numerically...
متن کاملVoltage increase of aqueous lithium-ion batteries by Li-ion conducting Li1.5Al0.5Ge1.5(PO4)3 glass-ceramic
In this research, a lithium ion conducting lithium aluminum germanium phosphate (LAGP) glass-ceramic with a formula of Li1.5Al0.5Ge1.5(PO4)3 was synthesized by melt-quenching method and subsequent crystallization at 850 °C for 8 h. The prepared glass-ceramic was characterized using X-ray diffraction analysis (XRD) and field emission scanning electron microscopy (FESEM). The XRD patterns exhib...
