Abstract: This invention relates to aqueous solutions that contain chlorine dioxide, particularly ultrapure aqueous solutions of chlorine dioxide that can be used, for example, in the field of human and veterinary medicine to disinfect surfaces, devices and instruments, as well as a process for producing such aqueous solutions of chlorine dioxide. In particular, this invention is a process for producing an aqueous solution of chlorine dioxide in which a previously produced aqueous solution of chlorine dioxide is treated so that an ultrapure aqueous solution of chlorine dioxide is obtained. The invented process can be applied to all previously produced aqueous solutions of chlorine dioxide, regardless of the process used to produce these. The invented process can be used in particular to produce ultrapure aqueous solutions of chlorine dioxide much more easily and inexpensively from previously produced aqueous solutions of chlorine dioxide.

Abstract: The invention relates to highly effective disinfecting or sterilising cloths with chlorine dioxide as the main active ingredient. For this, the chlorine dioxide is only generated shortly before use by bringing a cloth impregnated with a chlorite or chlorate salt in contact with a clearly defined amount of a suitable activation agent that is fluid or dissolved or admixed in a fluid, and prepackaged as a single dose, for the generation of chlorine dioxide. In a preferred embodiment, the impregnated cloth and the activation fluid are packaged in a common packaging unit and the activation occurs by breaking through a barrier separating the cloth or the cloths and the activation fluid. In a further preferred embodiment, the packaging is a moulded part having two packaging spaces separated from one another by removable barriers, which can be converted into a moulded part with only one chamber via simple pressure in one direction.

Abstract: The present invention relates to a process for producing mixed metal oxide particles, in which particles from parent compounds are converted by contactless energy input. The invention also relates to a process for coating bodies, preferably transition metal- or metal particles, transition metal- or metal oxide particles, transition metal- or mixed metal oxide particles, or silicon- or sulphur particles, especially preferably particles having a mass of less than one milligram and being in the form of grains, fibers, hollow fibers, or 2D structures, by heating with the exclusion of oxygen in the presence of a carbon source.

Abstract: The invention relates to a new generation of alkali-ion-sulphur batteries in which specific sulphur allotropes, particularly the Psi allotrope of sulphur, are used as the active material of the cathode. Alkali metals or alkaline-earth metals are used as anodes. A preferred production method describes the production of the Psi-sulphur fibres by a special form of electrospinning. Another preferred production method describes the addition of the cation source in liquid form during the production of battery stacks. Finally, the invention relates to specific preferred novel forms of embodiment of alkali-ion-sulphur batteries, which are characterised by significant advantages in terms of capacity and service life.

Abstract: A static devolatilization apparatus (1) for germ reduction of a fluid is disclosed. The apparatus (1) comprises a housing (10), an inlet (12), an outlet (14), a fluid-contacting surface (20) comprising a biocide (22) embodied to reduce the germ count of the fluid (2), wherein the fluid-contacting surface (20) is a fluid-contacting surface (20) of a static mixing element (30). The present invention further relates to a process for reducing the germ count of a fluid containing germs (2?) using the apparatus (1) and also to the use of the apparatus (1) in the germ reduction of fuel oil, of food products, or water decontamination, preferably decontamination of waste water, industrial process water, or the treatment of drinking water.
