Application


  • Mass spectrometry standards: A significant advancement was made in developing an enantioselective high-performance liquid chromatography-tandem mass spectrometry method for the quantitative determination of methorphan and its O-demethylated metabolite, dextrorphan-d₃, in human blood, specifically for forensic applications in post-mortem samples. This method underscores the utility of stable isotope-labeled compounds like dextrorphan-d₃ in precise pharmacological research (Lo Faro et al., 2023).

Features and Benefits

Preparation of new stabilized, oxide ion-conducting, bismuth vanadate phases by a microwave assisted method, from V2O5, Bi2O3 and other solid oxides, was reported. These ceramics show promise in solid oxide fuel cells, water-vapor electrolyzers and oxygen sensors.

We investigated the generation of frequency up-converted femtosecond laser pulses by nondegenerate cascaded four-wave mixing (CFWM) in a bismuth-oxide glass (BI glass). Broad-bandwidth light pulses with different propagation directions were simultaneously obtained by using two small-angle crossing femtosecond laser pulses
