Polymeric porous particles have a continuous organic solid phase and at least two sets of discrete pores that are isolated from each other within the continuous phase and that have different average sizes. One set of discrete pores has a larger average size than another set of discrete pores by at least 50%. At least one set of discrete pores is free of detectably different marker materials. There porous particles can be prepared using evaporative limited coalescence techniques with especially chosen discrete pore stabilizing hydrocolloids to protect the pores during formation and to provide the different average sizes. The resulting porous particles can be incorporated into articles of various types and having various shapes.

In a method for controlling shrinkage of a composite, a dried hydrophobically modified cellulose-based fiber is exposed to a slow acting resin system having a first curing time. An excess amount of the slow acting resin system is removed to separate out the pre-wetted hydrophobically modified cellulose-based fiber. The pre-wetted hydrophobically modified cellulose-based fiber is mixed with a fast acting resin system to form a mixture. The fast acting resin system has a second curing time that is less than the first curing time. The mixture is molded at a predetermined temperature. The fast acting resin system is cured prior to the slow acting resin system, and the slow acting resin system flows into free space within the curing fast acting resin system prior to the slow acting resin system being cured.

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

A cross-linkable nitrile rubber composition including a highly saturated nitrile rubber (A) containing α,β-thylenically unsaturated nitrile monomer units in a ratio of 5 to 50 wt % and having an iodine value of 120 or less, a polysaccharide polymer staple fiber (B) having an average fiber diameter of 1 μm or less, and a cross-linking agent (C), wherein a ratio of content of the polysaccharide polymer staple fiber (B) is 0.5 to 30 parts by weight with respect to 100 parts by weight of the highly saturated nitrile rubber (A).

A natural composition for 3D printing comprising alginate from brown seaweed and cellulose nanofibers, wherein the cellulose nanofibers originate from cellulose from the same brown seaweed sample(s) as the alginate.

A gas-barrier composition including nanocellulose containing at least one of a sulfuric acid group, a sulfo group, or a phosphoric acid group; and a reactive crosslinking agent.

It is provided a microspherical structure comprising an external shell of structured cellulose nanocrystals (CNCs) and at least one polymer, and a core, wherein the core can be hollow or filled with an immiscible medium. It is also provided a method for producing the same comprising spray-drying the mixture of CNCs and polymer through an atomizer and into a drying chamber forming droplets, wherein the solvent used to suspend the CNCs is evaporated and the microspherical structures are formed. These microstructural spheres can have wide industrial, medical and pharmaceutical applications, whereby their ingredients and structure are tuned and controlled.

A composite material is formed by preparing mass particles consisting of a fibrous material at least partially derived from recycled post-consumer materials and preparing particles of a binding material consisting of a thermoplastic material at least partially derived from recycled post-consumer material. The prepared mass particles and particles of binding material are mixed together such that the binding material liquifies and coats the mass particles which are subsequently then pressed together to form a composite article in which the mass particles typically occupy between 35% and 60% by weight of the composite material and the binding material occupies between 40% and 60% by weight of the composite material. The composite material is suitable for replacing concrete, wood, or other construction, manufacturing or industrial materials, and possesses properties that in some applications may be equal or superior such materials.

The embodiments relate to a biodegradable polyester resin composition, to a nonwoven fabric, to a film, and to processes for preparing the same in which the biodegradable polyester resin composition comprises a specific diol component and a specific dicarboxylic acid component and may further comprise nanocellulose, whereby the biodegradability, flexibility, strength, and processability are enhanced. Since the biodegradable polyester resin composition has enhanced biodegradability, flexibility, strength, and processability as compared with the conventional natural biodegradable polymer widely used, it can be applied to various fields such as films, packaging materials, and nonwoven fabrics to show excellent characteristics.

A method of producing biopolymer films is disclosed. The method includes pre-treating a carbon source, preparing a basal media, preparing an inoculum and fermenting the carbon source using the inoculum in the basal media so as to selectively modify the metabolic pathway of the microorganism to produce a biopolymer. Further, the method includes recovering the biopolymer resulting from the step of fermentation and blending the biopolymer with at least one blending agent to produce one or more biopolymer films.
