Abstract: Method for the production of cellulose yarns from recycling cellulose material, wherein the method includes the following steps: (a) dissolution of the recycling cellulose material in a molten ionic liquid; (b) adapting the conditions such that active substances dissolved or dispersed in the molten ionic liquid or generated in situ in the molten ionic liquid act to degrade non-cellulose material initially contained in the recycling cellulose material and contained in the molten ionic liquid due to the dissolution of the recycling cellulose material, wherein the active substances can already be present during (a) or can be added after (a) and before or during (b).

Abstract: Method for making a porous graphene layer of a thickness of less than 100 nm with pores having an average size in the range of 5-900 nm, includes the following steps: providing a catalytically active substrate catalyzing graphene formation under chemical vapor deposition conditions, the catalytically active substrate in or on its surface being provided with a plurality of catalytically inactive domains having a size essentially corresponding to the size of the pores in the resultant porous graphene layer; chemical vapor deposition using a carbon source in the gas phase and formation of the porous graphene layer on the surface of the catalytically active substrate. The pores in the graphene layer are in situ formed due to the presence of the catalytically inactive domains.

Abstract: Provided herein is a formulation containing a PPG/PEG block-copolymer (I) on average having PEG-blocks in the range of 37-45 terminated on both sides with on average in the range of 6-11 PPG blocks. The PPG/PEG block-copolymer can be end capped with hydrocarbon systems like for example n-butyl. The PPG/PEG block-copolymer (I) is chosen to have a DSC-melting point according to DIN ISO 11357 in the range of 15-37° C. to provide for a cool touch effect and can be applied without encapsulation. Furthermore uses of such a formulation and textiles treated with such a formulation are proposed.

Abstract: A multifunctional, responsive functional layer on a substrate, such as textiles, paper and plastic materials, includes at least one first and a second functional component, of which at least one of the second functional components meets the chemical-functional and constitutional specification for responsive behavior and thereby can be reversibly switched by an outer stimulus. The first and second functional components differ with respect to the intrinsically specified properties thereof and are matched to each other, wherein at least one of the functional components on the substrate is present as a physical-chemical compound. Methods are disclosed for producing the multifunctional, responsive functional layer, which enable the combination of functions, such as moisture management, soil release, antistatic, hydrophobicity, hydrophilicity, oleophobicity, controlled release, and conductivity.

Abstract: The present invention relates to a medical implant which is equipped with an antimicrobial composition which comprises silicon dioxide and metal-containing nanoparticles, and processes for producing the medical implant.

Abstract: A particle composite for incorporation in a finish coating includes particles having various sizes from 0.01-10 ?m and encased by at least one layer containing a coating mass. The particles are chemically fixable and have substantially the same function on the surface as that in the host matrix of the finish layer. Methods for producing the particle composite are disclosed, wherein hyperstructures leading to an enhancement of the oil- and dirt-repellent effect are formed by the combination of smaller and larger particles.

Abstract: A textile implant includes at least one thread having a polymeric core and a polymeric sheath which surrounds the polymeric core at least partly, wherein the sheath includes a composition including at least one silica-supported antimicrobial active agent.
