The present invention relates to a process for electrochemical preparation of sodium alkoxide. The process is performed in an electrolysis cell having three chambers, wherein the middle chamber is separated from the cathode chamber by a solid-state electrolyte permeable to sodium ions, for example NaSICON, and from the anode chamber by a diffusion barrier, for example a membrane selective for cations or anions. The geometry of the electrolysis cell protects the solid-state electrolyte permeable to sodium ions from acidic destruction by the pH of the anolyte that falls in the course of electrolysis. The anolyte used in the process is a brine also comprising carbonates and/or hydrogencarbonates as well as NaCI. Such brines are typically formed in the pretreatment of raw brines that are obtained from sea salt, for example. In this pretreatment, metal ions other than sodium, for example Sr2, Ba2+, Ca2+, Mg2+, are removed from the raw brine by means of carbonate precipitation, and hence a brine comprising NaCI and carbonate and/or hydrogencarbonate is obtained. The process according to the invention solves the problem that CO2 from these carbonates and/or hydrogencarbonates forms in the electrolysis cell during the electrolysis of this brine obtained from the pretreatment. It prevents the formation of a gas bubble in the electrolysis cell that disrupts electrolysis and reduces the contamination of the chlorine with CO2.

The invention pertains to a computer-implemented method of establishing an epigenetic clock for an avian species, the method comprising (a.) identifying and determining the methylation levels of specific CpG sites within the genomic DNA obtained from a plurality of different biological sample materials deriving from the avian species and representing specific time points within the chronological lifespan of this avian species, (b.) excluding all CpG sites associated with single nucleotide polymorphisms (SNPs) from the CpG sites identified in step (a.), (c.) excluding all CpG sites located on the sex chromosomes (Z and W) from the CpG sites obtained in step (b.), (d.) performing a tissue-specific normalization step for the CpG sites obtained in step (c.), and (e.) correlating the CpG methylation levels of the CpG sites obtained in step (d.) with chronological age using a penalized regression model.
The invention relates to a composite body comprising a porous layer (1) made from oxide particles connected to one another and partially to the substrate, containing at least one oxide, selected from oxides of the elements Al, Zr,Ti and Si, preferably selected from Al2O3, ZrO2, TiO2 and SiO2, arranged on a porous substrate and in the intermediate spaces of the substrate, containing fibres, preferably made from an electrically non-conductive material, and comprising a further porous layer (2) at least on one side, having oxide particles connected to one another and partially to the layer (1) and containing at least one oxide, selected from oxides of the elements Al, Zr, Ti and Si, preferably selected from Al2O3, ZrO2, TiO2 and SiO2, wherein the oxide particles in the layer (1) have a greater average particle size than the oxide particles in the layer (2), wherein the average particle size (d50) of the oxide particles in the layer (1) is 0.5 to 4 µm and the average particle size (d50) of the oxide particles in the layer (2) is 0.015 to 0.15 µm, preferably 0.04 to 0.06 µm, characterised in that a polymer coating (PB) is provided on or above the layer (2), containing one or more polysiloxanes. The invention also relates to a method for producing corresponding composite bodies and to the use thereof, in particular in organophilic nanofiltration.
