Abstract: Techniques for standardizing a catalog of data and for using the standardized data to implement various APIs are disclosed. Non-standardized data is received. This data includes information describing items, customer information, and unstructured review data. The non-standardized data is converted to a standardized format, resulting in the generation of standardized data. The standardized data includes a hierarchy of defined categories. Each category is associated with a set of attribute types. The standardized data also includes anonymized profiles. The unstructured review data is also provided structure. A data model is generated based on the standardized data. Various APIs can then use the data model to perform operations.

Abstract: A button for a drug delivery device with a reduced operating loudness includes a plate-like button body forming a touch surface, wherein the plate-like button body is coupled by an axial supporting member to a noise-generating interface of the drug delivery device and movable into a longitudinal direction of the drug delivery device, wherein the plate-like button body includes a material composite with at least one first component consisting of a first material and at least one second component consisting of a second material different from the first material, wherein the at least one first component and the at least one second component are coupled via at least one coupling plane that is at least sectionwise slanted or perpendicular to the longitudinal direction. Further, the disclosure describes a button assembly for a drug delivery device which is shock resistant.

Abstract: Improved catalyst comprising iron and carbon nanotubes. The invention relates to a process for making a catalyst comprising carbon nanotubes and iron-based particles, the process comprising the steps of: a)preparing carbon nanotubes comprising iron-based particles by chemical vapour deposition of a vapour of a carbon-containing substance in the presence of an iron-containing substance; b) subjecting the carbon nanotubes comprising iron-based particles to oxidising conditions to selectively etch away graphite layers covering the iron-based particles, thereby exposing the iron-based particles at the surface of the carbon nanotubes and at least partially oxidising the iron-based particles; and c) subjecting the carbon nanotubes comprising iron-based particles to reducing conditions in order to at least partially reduce the iron-based particles. The catalyst may be used in the manufacture of hydrocarbons from carbon monoxide or carbon dioxide, or for carbon capture and utilization.
