Abstract: The invention relates to a compound of formula Ia or Ib wherein R1 represents —CO2R3, —COR4 or —R5, wherein R3 represents unsubstituted or substituted C1-C6 alkyl, R4 represents hydrogen, unsubstituted or substituted C1-C6 alkyl, and R5 represents hydrogen, unsubstituted or substituted C1-C6 alkyl, R2 represents —N+(R6)(R7)(R8)X? or a nitro group, wherein R6, R7, R8 independently of each other represent unsubstituted or substituted C1-C6 alkyl or unsubstituted or substituted —(CH2)n- with n=1 to 12 provided that at least two of the substituents R6R7R8 are C1-C6 alkyl, and X? represents a halide, sulphonate, unsubstituted or substituted acetate, sulphate, hydrogen sulphate, nitrate, perchlorate, or oxalate.

Abstract: An absorbent article for personal hygiene is provided and comprises a longitudinal axis, a transversal axis perpendicular to the longitudinal axis, a liquid permeable topsheet an acquisition layer, a liquid impermeable backsheet and an absorbent core. The absorbent core is located between the topsheet and backsheet and comprises an absorbent material. A width of the acquisition layer in a direction parallel to a transversal axis is less than a width of the topsheet in a direction parallel to the transversal axis. The absorbent article comprises a topsheet/acquisition layer laminate comprising the liquid permeable topsheet and the acquisition layer in a face to face relationship. The topsheet/acquisition layer laminate comprises three-dimensional protrusions extending from a plane of the topsheet/acquisition layer laminate. A Median Absorption Pressure (MAP) of the topsheet is equal to or larger than a Median Absorption Pressure of the acquisition layer, both according to the Capillary Sorption Test Method.

Abstract: The present invention provides novel nanoscale cellulose particles and also a process for their production. The cellulose-based particles obtained have volume-averaged particle sizes of less than 300 nm. These nanoparticles are produced from amorphous cellulose or by amorphization of cellulose, optional subsequent hydrolysis and by input of energy into a water-containing medium after or during dispersion.

Abstract: The invention refers to a method for the production of cellulose sulfate which is completely water-soluble and has an adjustable solution viscosity in aqueous solution, which qualifies the produced sodium cellulose sulfate (SCS) as auxiliary material with ideal biological compatibility for biological and medical applications, in particular it is suitable for the encapsulation and immobilization of biological objects, e.g. tissue, cells, microorganisms, enzymes or viruses in microcapsule.

Abstract: The present invention provides novel nanoscale cellulose particles and also a process for their production. The cellulose-based particles obtained have volume-averaged particle sizes of less than 300 run. These nanoparticles are produced from slightly oxidized cellulose and by input of energy into a water-containing medium after or during dispersion.

Abstract: The present invention relates to the manufacture of triblock polymer ligands (30) and nanoparticle complexes (80). The nanoparticle complexes (80) comprise a capped nanoparticle (10) and the triblock polymer ligand (30). The triblock polymer ligand (30) consists of a binding polymer (40), a hydrophobic polymer (50) and a hydrophilic functionalisable polymer (60). The binding polymer (40) attaches to the capped nanoparticle (10).
