  • Publication number: 20240052503
    Abstract: The invention relates to the synthetic functionalization of an anthraquinone molecule that is substituted with at least one hydroxyl or amino group. In some aspects of the invention a mixture containing said anthraquinone starting material, an aldehyde, a base, an optional solvent, and an optional catalyst is reacted with hydrogen and then with an oxidant. In other aspects of the invention the synthetic functionalization of the anthraquinone molecule takes place electrochemically rather than chemically, through the use of a divided electrolytic cell.

  • Patent number: 11806927
    Abstract: A method of providing high-speed three dimensional (3D) printing is described. The method includes producing at least one three dimensional (3D) printed part. Producing the 3D part includes continuously constructing to extend outwardly a diameter of a rotating cylindrical core via continuous deposition of a layer, and defining a first pattern in the continuously deposited layer corresponding to a cross-section of the at least one 3D printed part.

  • Patent number: 11794465
    Abstract: Fountain solution latent images are provided on an inking blanket without using laser-induced evaporation systems. Approaches include a rotatable charge retentive surface configured to receive an unfused toned electrostatic pattern of toner particles adhered thereto via electrophotography. The toner includes small diameter polymeric or inorganic particles that may have no color pigment to appear transparent or translucent. Fountain solution is disposed on at least one of the toner, the charge retentive surface and a transfer substrate. The transfer substrate is adjacent the charge retentive surface and forms a nip therebetween, with the transfer substrate sandwiching the unfused toned electrostatic pattern of toner particles and fountain solution against the charge retentive surface at the nip.

  • Patent number: 11161857
    Abstract: Compounds are synthesized with bicyclic amidinate ligands attached to one or more metal atoms. These compounds are useful for the synthesis of materials containing metals. Examples include pure metals, metal alloys, metal oxides, metal nitrides, metal phosphides, metal sulfides, metal selenides, metal tellurides, metal borides, metal carbides, metal silicides and metal germanides. Techniques for materials synthesis include vapor deposition (chemical vapor deposition and atomic layer deposition), liquid solution methods (sol-gel and precipitation) and solid-state pyrolysis. Copper metal films are formed on heated substrates by the reaction of copper(I) bicyclic amidinate vapor and hydrogen gas, whereas reaction with water vapor produces copper oxide. Silver and gold films were deposited on surfaces by reaction of their respective bicyclic amidinate vapors with hydrogen gas.
