Abstract: A process for the drying of inorganic hydrogels obtained from readily hydrolyzable compounds of the elements Al, Si, Ti, B, La, Zr, Cr, Sn, Th or Mg, and organic hydrogels based on gelatine, albumin or agar agar, from CO2, to give aerogels is easy to carry out industrially, and drying can be effected at from room temperature to 90 DEG C. The resulting aerogels are transparent and have a low bulk density and low thermal conductivity. The aerogels can be used as packing materials for liquid chromatography, as catalyst carriers, as substrates for enzymes and as adsorbents.

Abstract: Novel 6,13-diarylfluorubins of the formula in which Ar represents identical or different aryl radicals and in which Ar and/or the rings A and/or B are optionally substituted. Ar preferably represents optionally substituted phenyl or naphthyl. The fluorubins (I) are suitable for the dyeing of thermoplastics, in particular of polyamides, in bulk. The fluorubins (I) have high temperature stability and very good light fastness. They are additionally very stable in plastics, e.g. polyamide, with a flame-resistant finish.

Abstract: A dye laser which as dye contains at least one dye from the substituted violanthrene-5,10-dione, substituted isoviolanthrene-9,18-dione or substituted perylene series. On account of the high fluorescence quantum yield and the high light and heat resistance, the dyes are suitable for use in dye lasers.
