Abstract: The present invention relates to cell culture media comprising inorganic ester derivatives of tyrosine and/or cysteine. The poor solubility of tyrosine and the often non-sufficient stability of cysteine in cell culture media is overcome by substituting them with an inorganic ester derivative, e.g. with a phosphorylated derivative.

Abstract: The present invention relates to a process for colouring surfaces, in particular surfaces of foods, with effect pigments, preferably pearlescent pigments, based on flake-form substrates, where (i) the effect pigment is incorporated into a pasty, transparent, water-based material and (ii) the application medium prepared in step (i) is applied to the surface.
Abstract: Fluorene derivatives that are connected in one or more of the 1-, 1?-, 4-, or 4?-positions in any combination to a carbon atom of a diaryl substituted triazinyl or pyrimidinyl derivative. The fluorene derivatives are not spirobifluorene derivatives. The compounds are suitable for use in electronic devices, in particular organic electroluminescent devices, comprising these compounds. In some embodiments, the compounds are used as matrix materials for phosphorescent or fluorescent emitters as well as a hole-blocking or an electron-transport layer.
