Medical material and a method for preparing a biological tissue for a medical application are provided. The material is useful as a sealing element in a heart valve prosthesis. A method includes decellularizing the biological tissue by decellularizing solution to obtain an acellular extracellular matrix, solubilizing the extracellular matrix of the biological tissue, and crosslinking collagen fibers of the solubilized extracellular matrix.

An implant has a support structure (e.g., alloplastic) such as a stent or a scaffold, and a functional element (e.g., a heart valve) including or made of bacterial cellulose. At least a part of the support structure is embedded in the functional element or in an extension thereof so as to connect the functional element to the structural element via positive fit.

An aluminum electrolytic capacitor including an anode electrode, and a method for producing the anode electrode. The method includes providing an aluminum electrolyte including an ionic liquid and an aluminum salt, galvanically deposing an aluminum on an aluminum foil formed from the aluminum electrolyte, and anodically oxidizing a surface of the aluminum foil. The ionic liquid includes a pyrrolidinium cation and a halogenide. The aluminum electrolyte includes 50-70 mol. % of the aluminum salt based on a total substance amount of the ionic liquid and the aluminum salt. The galvanic deposition includes and is based on a deposition temperature ranging from 20&#xb0; C. to 100&#xb0; C., a current density ranging from 1 to 100 mA/cm, an applied potential ranging from &#x2212;0.1 V to &#x2212;1.0 V based on a potential of an aluminum reference electrode, and a deposition rate ranging from 1 to 50 &#x3bc;m/h.
