Femtosecond laser-induced reduction in Eu-doped sodium borate glasses
In this work, we report permanent reduction of Eu to Eu in sodium borate glasses by irradiation of near-infrared femtosecond laser. Glass composition of sodium borate was 85B2O3–15Na2O. The glasses were doped with 0.05, 0.1, and 0.5mol% Eu2O3. Absorption and fluorescence dynamics were studied to investigate valence state change of europium ions and the energy transfer between Eu and Eu ions. As...
متن کاملElectrolysis of a molten semiconductor
Metals cannot be extracted by electrolysis of transition-metal sulfides because as liquids they are semiconductors, which exhibit high levels of electronic conduction and metal dissolution. Herein by introduction of a distinct secondary electrolyte, we reveal a high-throughput electro-desulfurization process that directly converts semiconducting molten stibnite (Sb2S3) into pure (99.9%) liquid ...
متن کاملMolten Carbonate Fuel Cells for Electrolysis
The molten carbonate fuel cell (MCFC) has evolved to current megawatt-scale commercial power plants. When using the fuel cell for electrolysis (MCEC), it provides a promising option for producing fuel gases such as hydrogen, via water electrolysis, and syngas, via co-electrolysis of water and carbon dioxide. The molten carbonate cell can thereby operate reversibly as a dual energy converter for...
متن کاملMechanical Properties of Alkali Borate Glasses
A GLASS is, formally, a solid that solidifies without a well-defined melting point— defined as a singular temperature at which there occurs a discontinuous change in a physical property, for example specific volume, during transition between a liquid state and its corresponding solid state—but instead exhibits a continuous change in that property over a range of temperature. Glasses tend to inh...
متن کاملEffect of Cooling Rate on the Structure of Sodium Borate Glasses
Sodium borate glasses with two different composit ions have been prepared using cooling rates in the range 7 • 10" C / s 2 • 10 °C/s. Structural characterization has been carried out by X-ray diffraction, and glass transition temperatures have been measured by Differential Scanning Calorimetry. The samples exhibit slightly different density values and glass transition temperatures. However, rad...
