The present invention includes surface-interactive utensils comprising a foamed material that includes a simple nanocellulose element (NCE)-based matrix comprising redispersed or redispersible NCEs or a composite NCE-containing matrix comprising redispersed or redispersible NCEs. The invention also includes methods of manufacturing such utensils.

Provided are porogen compositions and methods of using such porogen compositions in the manufacture of porous materials, for example, porous silicone elastomers. The porogens generally include comprising a core material and shell material different from the core material. The porogens can be used to form a scaffold for making a resulting porous elastomer when the scaffold is removed.

A process for preparing water-absorbing polymer particles, comprising polymerization of a foamed monomer solution or suspension, drying, grinding and classification.

A hydrogel based on a cross-linked -polyglutamic acid and -polylysine polymer is obtained by cross-linking of -polyglutamic acid with -polylysine, and it is a polymer having the following constitutional unit, wherein, m is a natural number of 15 to 45, n is a natural number of 3900 to 17000, and x is a natural number of 5 to 40. It also discloses a preparation method of as-described hydrogel and its application in preparation as a medical wound dressing.

A High Internal Phase Emulsion (HIPE) foam having cellulose nanoparticles.
