  • Publication number: 20260048988
    Abstract: A method for producing graphite from paper for use as a filter or construction material provides a cost-effective, simple and sustainable method for producing graphite. Paper/wastepaper, paper shreds or paper strips are soaked in water in a suitable container for several hours. The soaked paper is mixed and comminuted using a suitable device until a paste or a mixture having a paste-like consistency forms. Sugar or starch is added to the paste as a binder. The paste is inserted into a suitable mold, and the water is subsequently pressed out of the paste by pressing or the paste is isostatically pressed, so that a pressed product is formed. The dewatered pressed product is removed from the mold and carbonized in a furnace at >1000° C. and then graphitized at >2000° C. (at most up to 3000° C.).

  • Publication number: 20250270143
    Abstract: The invention relates to a method for producing carbonised or graphitised 3D objects which aims to realise such 3D objects particularly simply, and by means of which more complex 3D objects can also be produced without faults in the structure. This is achieved by mixing a carbonisable or graphitisable material with a free-flowing organic adhesive or a free-flowing thermoplastic organic substance to produce a kneadable, largely dimensionally stable compound and shaping the compound into a 3D blank, and by a subsequent drying and degassing process at an increased temperature over a predetermined period of time and subsequent carbonising or graphitising of the 3D blank in a furnace in a protective gas atmosphere to produce a 3D object, the temperature necessary for carbonising or graphitising being approached with a low heating gradient.

  • Publication number: 20250040863
    Abstract: Systems and methods for providing spatiotemporal sensory inputs to participants to produce a stimulus map of the brain. A code generation model is sampled with a first encoding vector to produce a first video sequence, which is output to provide a first spatiotemporal sensory input to the participants. Neural response measurements are performed while the first spatiotemporal sensory input is being presented to each of the participants. An outcome function is determined based on the neural response measurements. A second encoding vector is produced based on the first encoding vector and the outcome function. The method is iteratively repeated with the second encoding vector, and any successive encoding vectors, until a defined set of stopping criteria for the outcome function is satisfied. Upon satisfying the defined set of stopping criteria, a resulting spatiotemporal sensory code is stored to form part of a stimulus map of the brain.
