Compositions and methods of producing paper-based materials are disclosed. In general, the techniques utilize an amine-containing polymer, such as chitosan, to functionalize one or more components of a mixture used to form materials such as paper-based materials. Such components can include the fibers of a pulp and/or filler particles. In one instance, either the pulp or the filler particles are functionalized, but not both. Such functionalization can improve the qualities of a paper-based material relative to when such functionalization is not utilized. Techniques and compositions are also described to further improve the qualities of a paper material by utilizing a complementary polymer which can couple with the amine-containing polymer.

Compositions and methods for treating hair are disclosed. Such compositions and methods can be used to modify hair properties, such as imparting and/or maintaining a level of softness or a conditioning effect on hair. In general, such compositions can utilize a copolymer having a plurality of polycationic segments, which can be joined by various other polymeric segments such as silicones and/or hydrophilic polymeric segments. The copolymer can be formulated as a highly-branched polymer, which can add substantivity to the hair to impart a conditioning effect. Various details of such copolymers are discussed, as well as methods of utilizing and making such copolymers.

Compositions and methods for treating substrates, such as fibrous materials, are disclosed. Such compositions and methods can be used to impart or maintain a level of oil repellency and/or water repellency in fibrous substrates such as paper-based materials and/or textiles. In general, such compositions can utilize a copolymer having a plurality of polycationic segments, which can be joined by various other polymeric segments such as silicones and/or hydrophilic polymeric segments. The copolymer can be formulated as a highly-branched polymer, which can have substantivity to a fibrous material to impart oil repellency and/or water repellency. In several instances, the copolymer can be formulated to be fluorine-free. Various details of such copolymers are discussed, as well as methods of utilizing and making such copolymers.

Compositions and methods of producing colored paper products and agents for making such products are disclosed. Surface-modified pigments can be manufactured to provide selected coloring in a paper product. The pigment can include filler particles that are bound to one or more dye components with a coupling agent, such as a silane coupling agent or a polymer such as a polycation. The pigment can also be formulated to produce a paper product with better particulate and/or fines retention, and/or higher strength by including components that can interact favorably with the fibers of a paper material. The surface-modified pigments can also be utilized to make coloring formulations such as inks for printers and other applications.
摘要:
A device identifies array accesses of variables in a program code that includes multiple arrays, and identifies array access patterns for one of the array accesses. The device also determines an order of the array access patterns identified for the array accesses, and calculates, based on the order, distances between the array access patterns. The device further shares address calculations amongst the array accesses associated with array access patterns with one or more of the distances that are equivalent.
摘要:
Disclosed herein are systems for removing particulate matter from a fluid, comprising a particle functionalized by attachment of at least one activating group or amine functional group, wherein the modified particle complexes with the particulate matter within the fluid to form a removable complex therein. The particulate matter has preferably been contacted, complexed or reacted with a tethering agent. The system is particularly advantageous to removing particulate matter from a tailing solution.
摘要:
Compositions and methods relating to the use of pigment compositions are revealed, which can be used to impart color to hair. For instance, treatment formulations that include a pigment-functionalized cationic polymer can be utilized. In some particular instances, a plurality of serially applied treatment formulations is used to improve the characteristics of hair coloring. In addition, other formulations or treatments, such as one or more sealing compositions, or a final coating formulation can also be used to impart other desired characteristics such as treatment durability. Other components of various formulations/compositions are also discussed. Processes for using such compositions/formulations are disclosed. Along with the compositions, kits can be assembled where various compositions/formulations are compartmentalized for storage until the time for application.
