## Abstract Oxygenβdeficient BaAl~2~O~4~, with strong optical absorption in the spectra range from 200 to 2500βnm, was prepared by a simple and economic thermal treatment of BaAl~2~O~4~ in a H~2~ gas flow. Further studies found that a molar ratio of oxygen vacancies of about 0.4β% existed in the pr

## Abstract A diverse mixture of volatile headspace analytes containing compounds with boiling points covering a range from β196Β°c to 145Β°c can be separated in approximately 40 minutes by multidimensional HRGC. The described provisional MDβHRGC Systems employ cryogenic sample collection, four 0.53
The adsorption isotherms of N, at 77K, CO, at 251, 273 and 298K, and SO, at 262 and 273K have been determined on a series of physically activated carbons with a wide range of micropore size distributions. Since the series includes carbons with very high burn-off, it shows the problems involved in th
