The invention provides a process for preparing a plasticised superporous hydrogel material comprising subjecting initial hydrogel material to treatment with an acidic solution, an optional treatment with a monovalent metal salt solution, freeze drying and plasticisation. Optionally, the process of the invention produces moulded plasticised superporous hydrogel material bodies that have one or more through-holes formed therein. The plasticised superporous hydrogel material of the present invention may be formulated as a suitable oral dosage form for use an appetite suppressant and for use to deliver a pharmaceutical and/or nutraceutical into a human or animal body.

A sound-absorbing material block, a method for preparing the same and application thereof are provided. The sound-absorbing material block includes three-dimensional open-cell foam, sound-absorbing material powder, a binder, a gel, and a cross-linking agent. The sound-absorbing material powder is bonded to each other and connected to the three-dimensional open-cell foam by means of the gel, the cross-linking agent, and the binder, by mass of the sound-absorbing material powder, the gel accounts for 1 wt % to 5 wt % of the sound-absorbing material powder, and the binder accounts for 1 wt % to 8 wt % of the sound-absorbing material powder, and by mass of the gel, the cross-linking agent accounts for 1 wt % to 10 wt % of the gel. The sound-absorbing material block according to the present disclosure reduces an additive amount of the binder, and significantly improves sound-absorbing performance and strength of the material block.

The present invention relates to a method of providing thermal and/or acoustic insulation to a structure, comprising the steps of: providing a substrate which comprises fibres; applying the substrate to the structure; blending the substrate with a binder composition before, during or after application of the substrate to the structure; allowing curing of the binder composition after the substrate and the binder composition have been applied to the structure; wherein the binder composition comprises at least one hydrocolloid. The present invention also relates to an insulated structure obtainable by said method.

The present disclosure provides a method for preparing a hydrogel composition with thermos-sensitive and ionic reversible properties and the hydrogel composition prepared by the method. Related application products of the hydrogel composition of the present disclosure include wound dressings, drug carriers, three-dimensional cellular scaffolds, soluble microspheres, and cell capture and release systems, wherein the hydrogel composition with thermos-sensitive and ionic reversible properties has good in vitro and in vivo stability and high biocompatibility, and is non-toxic. The hydrogel composition can be removed and replaced by washing with metal chelating aqueous solution at low temperature.

The invention features a composition comprising a self-healing interpenetrating network hydrogel comprising a first network and a second network. The first network comprises covalent crosslinks and the second network comprises ionic or physical crosslinks. For example, the first network comprises a polyacrylamide polymer and second network comprises an alginate polymer.

Films and packaging materials including biodegradable and edible components and pods created using these materials are described herein.

Pitch granules including a core made up of a first composition including at least one pitch, the composition having a penetrability at 25? C. of 0 to 45 1/10 mm, a ring-and-ball softening temperature (TBA) of 55? C. to 175? C., understanding the penetrability as measured according to standard EN 1426 and the TBA as measured according to standard EN 1427, and a layer encapsulating at least one portion of the surface of the core, the layer being made up of a coating composition including at least one anti-caking agent.

A method and a mineral wool product include a multiple of lamellae, such as a sandwich panel core. The product includes a plurality of lamellae cut from a mineral wool web, and bonded together by applying an adhesive on the surfaces of two adjacent lamellae to form a web-like product, wherein the adhesive comprises at least one hydrocolloid.

The invention relates to a mineral wool product comprising mineral fibres bound by a cured binder wherein the binder in its uncured state comprises at least one protein, and at least one enzyme.

A degradable nano-preservative film with photodynamic bactericidal activity and a preparation method therefor, and belongs to the technical field of antibacterial preservative films is provided. The present invention synthesizes nanoparticles with aggregation-induced emission characteristic by self-assembly of berberine that is a natural plant antibacterial component and citric acid. Under white light, the nanoparticles can generate a large amount of reactive oxygen species (ROS), thereby exhibiting efficient and durable antibacterial activity. Nanoparticles are prepared by adding the nanoparticles as a filler to a film-mixed solution composed of sodium alginate, pullulan and egg white. With photodynamic bactericidal activity, the present invention improves over current antibacterial preservative films having short lasting effect and which require direct contact to realize bactericidal effect.
