Abstract: The present disclosure relates to a carbon dioxide capture device comprising a first reactor and a second reactor both of which show a (photo)anode containing or connected to oxygen evolution and/or carbon dioxide evolution catalyst(s) and a (photo)cathode containing or connected to an oxygen reduction catalyst, wherein the first reactor comprises an anion exchange membrane placed between the porous (photo)anode and porous (photo)cathode, and the second reactor comprises a proton exchange membrane placed between the porous (photo)anode and porous (photo)cathode. On the porous (photo)cathode side of the first reactor there is a fluid inlet able to carry carbon dioxide, air and water, and on the side of the porous (photo)cathode of the second reactor there is a fluid outlet able to carry carbon dioxide and water.

Abstract: A hair component for use within a ponytail comprising at one end (1) means that can be pushed through the band used to create the ponytail joined to a second end (2) by a narrower neck section (5) so that the band is retained within the ponytail by the band between the two ends (1,2), the means at the second end (2) can be attached to a segment of hair so providing a hair extension. A hair extension comprising the attachment provided with a segment of hair is also provided.

Abstract: A hair accessory which can be inserted directly into a ponytail (6) and secured therein by means of the ring or band (2) already in place to form the ponytail to provide the user with the appearance of an thicker and longer ponytail. The accessory consists of a weft of hair and longitudinal extending gripping means (3). Once the gripping means is inserted into a ponytail, the device is reliant on the combination of the grip and the pressure from the ring ponytail to hold it in place, and the hair weft then blends in with the user's natural hair to create a thicker and longer ponytail.
