  • Publication number: 20210155764
    Abstract: Disclosed is a method for producing a nanofibrous non-woven material and a nanofibrous non-woven material with cross-linked gelatin nanofibers. The method includes producing gelatin nanofibers; producing a nanofibrous material using the produced gelatin nanofibers; and treating the nanofibrous material by a crosslinking agent for forming adhesion bonds in the nanofibrous material and to obtain the nanofibrous non-woven material.

  • Publication number: 20140186623
    Abstract: The present invention prescribes a new sol-gel method of preparing and formation of the metal oxide microtubes. According to the method firstly is prepared the precursor sol from metal oxides or mixtures of metal oxides and alkoxides, thereafter from the precursor sol are extruded the fibres, which are gelatinised afterwards until the inner sol which is less viscous of fibres is converted to thinner wall until alcohol from the precursor is left trough walls. The metal oxide microtubes are applicable as to conduct liquids or gasses, as ionic conductors, as catalyst carriers and as light emitters.

  • Patent number: 8597610
    Abstract: In the current invention a method for the preparation of an oxide material was described that involves bringing the sol onto the substrate, the gelation of the solution and thermal treatment of the gel. Alkoxides are used as precursor materials for the sol preparation and substrate free structures are employed for the manufacturing of the oxide material. A gel film with thickness ranging from 5 nm to 1 ?m is created onto the sol layer. The gelled film is separated into pieces by self organizing and the gelled part is disconnected from the substrate. Substrate free tubular structures with diameters ranging from 0.01-100 ?m are formed of the gel film which are then heated at temperature range of 200-1600 C during a period of 5 minutes to 10 hours. The manufactured oxide materials are employed as catalysts, gas sensors, stationary phases of chromatographic columns, composite materials, thermal isolation materials and micro- or nano electronic mechanical systems (MEMS or NEMS) components.

  • Publication number: 20100274031
    Abstract: Methods for producing amrubicin and structural analogs thereof. The present invention encompasses synthetic pathways for the production of amrubicin (Formula I) and structural analogs thereof. The synthetic pathways of the present invention preferably employ as a starting material an anthracycline compound having the generic Formula II: Compounds of Formula II may have any combination of the following identities for the indicated moieties: R1, R2, R3, R4, and R8 may be H, OH, or alkoxy; R5 may be H, alkyl, or alkoxycarbonyl; R6 may be H or alkyl; R7 may be OH or alkyl. In certain embodiments, ?-rhodomycinone or daunomycinone may be used as starting materials according to Formula II. The present invention employs a compound of Formula II as part of a semi-synthetic method that combines traditional chemical synthetic steps with biosynthetic steps to produce amrubicin, derivatives thereof, and structural analogs thereof.
