Provided is a hookah holder comprising: a) a ring configured for accepting a base of a hookah; b) a plurality of connectors on a bottom of the ring for securing the ring to a surface; wherein the hookah's base in placed inside of the ring and is secured by the hookah holder. The connector can be a suction cup. The suction cups can be spaced apart and arranged in a concentric fashion in relation to the ring. The hookah holder can be made from silicone. The hookah holder can be fabricated from one piece. The hookah holder can be manufactured by casting silicone in a cast. The ring can have a diameter of about 100 mm to about 200 mm. The cavity can be formed inside of the ring and be configured to receive a hookah base. The ring can have an upper portion and a lower portion, with a cavity formed by the upper and the lower portion, the cavity configured to receive a hookah base. The lower portion can extend more towards center of the ring than the upper portion. The cavity can have a shape of a V with a curved bottom.

The present invention relates to a kit for indirect production of composite inlays, comprising a polymerizable material for production of a dental model, a polymerizable material for production of an inlay, a polymerizable material for luting of a crosslinked and non-sand-blasted, non-silanized, non-etched, non-primed and non-roughened composite inlay, the surfaces of which have been fully polymerized, in the cavity. Also disclosed is a polymerizable material for increasing the bond strength between the polymerizable material for luting of a crosslinked non-sand-blasted, non-silanized, non-etched, non-primed and non-roughened composite inlay, the surfaces of which have been fully polymerized, in the cavity, and the hard substance of the tooth, and an acid solution for surface etching of the hard substance of the tooth. The invention further relates to methods for producing a composite inlay.

Microneedle arrays and methods of forming the same can include one or more bioactive components bonded to a biocompatible material such that the one or more bioactive components are cleavable in vivo to release the bioactive component from the biocompatible material.

A composite film having a high dielectric permittivity engineered particles dispersed in a high breakdown strength polymer material to achieve high energy density.

A method employs a first polymeric material to deposit first and second pattern layers laterally shifted from each other such that laterally shifted pattern layers form between them an empty volume with a variable cross-section that varies along with the first and second pattern layers. A second polymeric material is cast in the empty volume between the first and second pattern layers to cast a complex-shaped 3D object identical in shape to the empty volume between the first and second pattern layers. Radiation is applied to cure the first and second polymeric materials. The first polymeric material is a water breakable material composition including acrylamide, methacrylamide, acrylate, acrylic acids, and acrylic acid salts, hydroxy(meth)acrylate, carboxy(meth)acrylate, acrylonitrile, carbohydrate monomers, methacrylate and polyfunctional acrylics.

The invention relates to a sensor element for detecting at least one analyte in a body fluid or in a body tissue, particularly for determining at least one metabolite concentration in a body fluid. The sensor element comprises an implantable, one-piece shaped body, which comprises a sensor end and a coupling end. The shaped body comprises, in the area of the sensor end, at least one sensor area, which comprises at least one sensor material. The sensor material changes at least one optically measurable property in the presence of the analyte. The shaped body also has at least one optically transparent coupling part, which is designed to transmit electromagnetic radiation in at least one spectral range between the sensor area and the coupling end. In the sensor area, the shaped body has at least one optically transparent matrix material, and the analyte can at least partially diffuse through the matrix material to the sensor material. The sensor material is embedded in the matrix material. The coupling part is formed at least partially by the matrix material.
