  • Patent number: 10780613
    Abstract: The present invention relates firstly to a method for reproducing a stem cell niche of an organism. The invention further relates to a reproduction of a stem cell niche of an organism. According to the invention, an image of a tissue of an organism is generated, which tissue comprises at least one stem cell niche. The image is filtered in order to obtain a structural pattern of the imaged stem cell niche. In a further step, a lithographic mask is generated from the structural pattern. According to the invention, a starting material of a substrate is structured by means of indirect or direct application of the lithographic mask, whereby a structured substrate is obtained which represents the reproduction of the imaged stem cell niche of the organism. The reproduction can be characterised as biolithomorphic.

  • Publication number: 20200168433
    Abstract: The invention relates to a method of imaging a sample, said sample mounted on a sample holder in an electron microscope, the electron microscope comprising an electron source for generating a beam of energetic electrons along an optical axis and optical elements for focusing and deflecting the beam so as to irradiate the sample with a beam of electrons. The sample holder is capable of positioning and tilting the sample with respect to the electron beam. The method comprises the step of acquiring a tilt series of images by irradiating the sample with the beam of electrons, and concurrently changing a position of the sample during acquisition of the images, so that each image is acquired at an associated unique tilt angle and an associated unique position.

  • Patent number: 10527116
    Abstract: A brake disc having a friction ring and a hub produced as a separate element and arranged inside the friction ring according. Recesses are configured in the friction ring on the inside to connect the hub to the friction ring and corresponding projections are formed on the hub, which projections engage in the recesses of the friction ring in order to be able to transfer torque from the friction ring to the hub. The recesses have an undercut at least partially in a radial direction, as viewed looking inward from the outside. The disc is simple and cost-effective to manufacture and has an acoustically advantageous operating performance, in particular in the case of thermal expansion.

  • Publication number: 20180265652
    Abstract: Disclosed are macroscopic systems of highly concentrated, cross-linked biopolymers. The macroscopic system is created by combining a biopolymer with a cross-linking agent, submerging the resulting product in an aqueous solution which contains additional cross-linking agents, to allow the biopolymer to undergo a second cross-linking process. The resulting macroscopic biopolymer has an increased biopolymer concentration and increased longevity within the body.

  • Publication number: 20170296673
    Abstract: The present invention discloses a drug delivery system comprising at least one hydrophobic matrix and at least one pharmaceutically active compound. The hydrophobic matrix comprises at least one hydrophobic solid component and at least one hydrophobic liquid component. The pharmaceutically active compound may comprise a biological cell or a biopolymer. The hydrophobic matrix conserves the activity of and protects the functionality of the biological cell or biopolymer in hostile environment, at elevated temperature, cold temperatures or a combination thereof. The present invention also discloses the use of the drug delivery system in a kit for diagnostic or analytical purposes. Additionally, the present invention discloses the use of the drug delivery system to deliver the pharmaceutically active compound to a subject who has or is suspected of having a pathophysiological condition.

  • Publication number: 20170252446
    Abstract: Disclosed are methods of making stable nanoparticle suspensions wherein one or more nanoporous or mesoporous materials are used to absorb and remove one or more non-tolerated surfactants from the nanoparticle suspensions. Also provided are methods of making stable nanoparticle suspension formulations wherein one or more macromolecular or colloidal stabilizers or tolerated surfactants are simultaneously added to further stabilize the nanoparticle suspension formulation. Thus to prevent a collapse of the suspension, one exchanges or replaces the surfactants that are not tolerated, by one or more tolerated surfactants or by macro-molecular/colloidal stabilizers.
