Embodiments described herein generally relate to methods of homogeneous wetting of biopolymers, derivatives therefrom and synthetic polymers, and, their applications.

Methods of fabrication of concentrated and homogeneously wetted massive polymers and applications thereof

The invention relates primarily to a processing method of biopolymers by means of solvent/solvent mixtures or multiphase solvent systems by means of which said polymers can be changed in their mechanical and qualitative features and processed more easily.

Processing method for biopolymers using solvent combinations

The present invention relates to methods of providing biocompatible/biodegradable hydrogels obtained by crosslinking of biopolymers (for example polysaccharides or proteins) in the semi-solid (modelling-clay like) state at water content below 70% by weight. The resulting materials can be applied in medicine, pharmacy and/or in cosmetics.

Crosslinking of biopolymers in a semi-solid state

A method for manufacturing a drug-delivery composition includes providing at least one pharmaceutically active compound, a dry powder comprising at least a polymer, and an aqueous solution. The dry powder, the pharmaceutically active compound and the aqueous solution are mixed to form a paste-like or semi-solid drug-delivery composition, wherein the aqueous solution is added in an amount of less than or equal to twice the total dry mass of the dry powder.

Polymeric drug-delivery material, method for manufacturing thereof and method for delivery of a drug-delivery composition

A method for manufacturing a drug-delivery composition includes providing at least a pharmaceutically active composition, providing a hydrophobic matrix; and mixing the hydrophobic matrix and the pharmaceutically active composition to form a paste-like or semi-solid drug-delivery composition.

Hydrophobic drug-delivery material, method for manufacturing thereof and methods for delivery of a drug-delivery composition

The starch composition comprises a cationic, cross-linked starch that is partly swollen and partly gelatinized. It has a gelatinization coefficient gT smaller than 0.7 with T the jet cooking temperature. The starch composition suitably comprises a wheat starch or a blend of a wheat starch and another starch, for instance a root or tuber starch.

Starch composition for use in paper manufacture

The invention relates to capsules coated with a polyelectrolyte shell and methods for the production thereof.

Production of nanocapsules and microcapsules by layer-wise polyelectrolyte self-assembly

A method for making an article comprising a core material and a coating thereon, the method comprising the steps of: (a) providing the core material; (b) applying one or more layers of a crosslinkable polycationic material, wherein the polycationic material is a reaction product of: (i) an epoxide of formula (I) wherein X equals bromo, chloro, iodo, or cyano, and R, R, R, R, independently of one another, are selected from the group consisting of hydrogen, linear or branched C-C-alkyl, and linear or branched C-C-alkyl which is substituted with halogen, and(ii) a polymer having repeating units comprising one or more secondary or tertiary amine group(s);(c) applying one or more layers of a polyanionic material; and(d) cross-linking the layers of polyelectrolytes formed by steps (b) and (c). The articles obtainable by the method of the invention have desirable characteristics regarding adherence to the core material, durability, hydrophilicity, and wettability and are thus useful for the manufacture of medical articles such as ophthalmic devices.

Cross-linkable polyionic coatings for medical devices

The invention concerns a process for encapsulating pigment particles, which comprises

Polyelectrolyte-encapsulated pigments

The present invention relates to a pyrotechnic system, system-compatible pyrotechnic objects, and a firing method tailored to the system. The system comprises a starting device having multiple receptacles, having a connection channel between each of the receptacles. The receptacles are filled with the pyrotechnic objects, the first receptacle is provided with an additional ignition device, and the pyrotechnic object located therein is ignited. An igniter externally positioned on the pyrotechnic object conducts the ignition energy into the interior and simultaneously via the connection channel into the neighboring receptacle. A pyrotechnic object located therein is ignited. The igniter externally positioned on the pyrotechnic object partially causes a time delay. The delay time may be set by twisting the pyrotechnic object in relation to the connection channel. The choreography of fireworks may be designed through the combination of a starting device with selected pyrotechnic objects in connection with the setting of the delay time.

Pyrotechnical system, pyrotechnical object and burn off method

The invention concerns a method for producing nanocapsules and microcapsules comprising a polyelectrolyte shell by surface precipitation from the solution, by applying a shell to template particles comprising the steps (a) providing a dispersion of template particles of suitable size in a salt-containing liquid phase which contains the components required to form the shell in a dissolved form and (b) precipitating the components from the liquid phase onto the template particles under conditions which enable the formation of a shell around the template particles that has a thickness of from 1 to 100 nm.
