Abstract: A carrier for cell culturing that contains a multiwell plate, where at least one of the wells of the multiwell plate has a porous substrate having the porosity of ?90% and adapted for cell culturing, and the porous substrate adheres to the surface of the well. A method for preparation of the carrier for cell culturing is also provided.

Abstract: A material for ballistic protection includes multiple compact layers of ballistic fiber and, between the layers of ballistic fibers, inserted at least one intermediate layer of non-Newtonian fluid exhibiting an increase in viscosity resulting from an increase in shear stress optionally containing particles having the size of from 1 to 700 nm or antiplasticizing agents. The intermediate layer is placed either directly between layers of ballistic fiber or between the layers on a packing or a perforated packing or applied on a fabric. A method of preparation of the material is also disclosed. This material is flexible and has a low weight and can be used, in particular, for bulletproof vests, combat helmets, personal body armor and/or for shielding light infantry and passenger automobiles.

Abstract: An abrasion resistant material includes a polymeric matrix composite, preferably an amorphous thermoplastic or a resin containing homogenously dispersed nanoparticles ranging in size from 1 to 50 nm, further combined with clusters of the nanoparticles, or a combination of nanoparticles of different sizes within the above-stated range. A method of preparation of, and automotive parts containing, this material are also disclosed.

Abstract: A method for producing a tooth stump structure that is to be anchored in a root canal comprises the following steps: flexible needles are introduced one after the other into a recess in the form of a root canal or into an exposed cavity; the length of the protruding ends of the needles is adjusted to the form of a core of the stump structure, the core is then modelled from a semi-liquid, polymerizable composition and subsequently hardened; and an outer jacket of a crown is applied to the core. The tooth stump structure produced by said method is formed by a structural core made of a hardened composition, wherein individual flexible needles are anchored in said core and protrude therefrom, a cross section of the needles being circular, elliptical or polygonal and their diameter ranging from 0.1 to 0.8 mm. The protruding parts of the needles occupy a space that corresponds essentially to the space of the root canal or the cavity.
