A process for treating a sulfurous fluid to form gypsum and magnesium carbonate, whereby the sulfurous fluid is scrubbed with a sequestrating agent to yield a scrubbed fluid, gypsum and magnesium sulfate. The flue gas desulfurized gypsum is isolated from the magnesium sulfate solution by filtration or centrifugation. The magnesium sulfate is reacted with a carbonate salt to produce a magnesium carbonate whereby the reaction conditions are controlled to control the properties of the magnesium carbonate produced.

The present invention provides, inter alia, biocompatible porous structural materials made exclusively or almost exclusively from nanocellulose fibers (CNF), CNC, or bacterial cellulose, as well as processes for making and using provided compositions. Provided compositions may possess specifically tailored mechanical strength properties and have a design-controlled porosity that is homogeneous or graded, depending on the application. Provided compositions may be manufactured by the controlled dewatering of suspensions of CNF. In some embodiments, provided compositions may include a solids concentration of about 10% to about 95% by weight. Controlled water removal and pore homo- or heterogeneity may be accomplished by controlling capillary, hydrostatic and evaporative processes in the environment of a porous mold around the CNF slurry. A freeze drying or vacuum drying step may be used to complete the drying process, locking in the porous network structure resulting in a predetermined porosity (pore volume/total volume), and pore size distribution.

The present disclosure is drawn to print media, laminated decor products, and methods of making the same. In one example, a print medium can include an open paper substrate and a multivalent metal salt treatment applied to the open paper substrate at a multivalent metal salt loading into the open paper substrate at from 0.5 gsm to 5 gsm. The open paper substrate can include wood fiber including softwood fiber, hardwood fiber, or a blend of softwood fiber and hardwood fiber; binder including starch, protein, or hydrophilic polymer; and from 20 wt % to 50 wt % of TiO.sub.2.

A method for preparing a binder composition containing water, plant fibers and mineral fillers, wherein the method comprises: preparing a suspension of plant fibers and mineral fillers in water, the weight ratio between the plant fibers and the mineral fillers being comprised between 99/1 and 2/98, refining this suspension, and obtaining a binder composition wherein the refined fibers have a mean size of between 10 and 700 μm, and wherein the refined fibers, at least partially, embed the refined mineral fillers,
wherein refining is carried out in the absence of any grinding medium made of ceramic or metal.

A method of making a mineralized fiber having a fiber core and a calcium carbonate shell can include admixing fibers with green liquor and adding CaO to generate a causticization reaction that results in a calcium carbonate shell coating forming around the fibers.
