Abstract: Additive-polymer precursor materials for filaments (e.g., for three-dimensional (3D) printing) are provided, as well as methods of fabricating and using the same. One or more two-dimensional (2D) additive materials (e.g., nano materials, such as nanosheets) can be mixed with a polymer base to give an additive-polymer precursor composite material. The additive material can be dissolved in a first solvent to give an additive solution, and the polymer can be dissolved in a second solvent to give a polymer base. The additive solution can be mixed with the polymer base to give a mixed solution. Solvent casting can then be performed on the mixed solution to evaporate the solvent(s) and give the additive-polymer precursor composite material, which can have a layered structure.

Abstract: A charging device for connecting an electrical energy store of a motor vehicle to a charging station for electrical energy includes a charging cable having at least one line for conducting a charging current and at least one connection element via which the charging cable is connectable to a corresponding connection element between the energy store and the charging station. At least one latent heat store is provided on the charging cable and/or on the at least one connection element and can be used to absorb heat generated during the charging process.

Abstract: A computer system initiates a chat upon receiving a chat input from a user. The computer system records a chat state for the chat. When the chat is at the chat state, the computer system can operate to determine a search criterion from the chat input. The computer can then select a chat response from a chat library based at least in part on the chat state and the search criterion. The chat response can be communicated to the user.

Abstract: A system receives a chat query based on a user interaction on a computing device of user. The system parses the chat query to identify one or more word patterns in the chat query, and determines a matching plug-in from the plug-in library based at least in part on the one or more word patterns in the chat query. The system utilizes the matching plug-in to access one or more resources and determine a chat response for the chat query, and transmit, over the one or more networks, the chat response to the computing device of the user.
