Abstract: An arrangement for the electrolysis of carbon dioxide, includes: an electrolytic cell having an anode and a cathode, wherein the anode and cathode are connected to a voltage supply, wherein the cathode is configured as a gas diffusion electrode to which a gas compartment is attached on a first side and a cathode compartment is attached on a second side; an electrolyte circuit connecting to the electrolytic cell; and a gas supply for supplying carbon dioxide-containing gas into the gas compartment, wherein one or more channels are arranged in the gas compartment, wherein the channels are at least partially in contact with the gas diffusion electrode and are configured for transporting electrolyte fluid passing through the gas diffusion electrode to a lateral region of the gas compartment.

Abstract: The invention relates to a method for determining a tissue type of a tissue of an animal or human individual, in which method: electromagnetic radiation (26) emitted by a tissue sample (24) of the tissue is sensed (10) by means of a radiation sensor (22), the radiation sensor (22) providing a sensor signal (28) in accordance with the sensed electromagnetic radiation, and the sensor signal (28) is evaluated (12) by means of an evaluation unit (30) in order to determine and output the tissue type. The problem addressed by the invention is that of enabling improved determination of the tissue type. According to the invention, the evaluation unit (30) is a self-learning evaluation unit (30) that is initially trained (14) by means of training data sets (32) on the basis of at least one model, which is based on a method for machine learning, the training of the evaluation unit being conducted by means of such training data sets (32) each comprising a training sensor signal with an associated training tissue type.

Abstract: The present disclosure relates to measuring light emission. The teachings thereof may be embodied in emission-measuring devices. For example, a device may include: a sample region; an illumination unit for irradiating the sample region and a sample positioned therein; and a radiation detector. The illumination unit may include: a radiation source; a first dispersive element arranged downstream, decomposing the radiation into spectral components; a first micromirror field arranged downstream; and a second dispersive element arranged downstream of the first micromirror field. The second dispersive element may unify spectral components selected by the first micromirrror field into a common excitation beam.

Abstract: An optical sensor is arranged in an indentation of a dust line, the indentation being equipped with at least one gas inlet nozzle for removing the dust from the optical sensor. Dust is transported through the dust line. An optical property of the dust is measured using at least one optical sensor arranged in an indentation of the dust line, and the dust is then removed from the optical sensor by blowing in air using the at least one gas inlet nozzle arranged in the indentation.
