A slurry for manufacturing gypsum board comprises calcined gypsum, water, a foaming agent, and a coalescing agent. The foaming agent imparts a plurality of bubbles in the slurry. Typically, a foam is pre-generated with the foaming agent and the foam is used to form the slurry such that the foam imparts the plurality of bubbles in the slurry. The coalescing agent coalesces the plurality of bubbles imparted by the foam. Typically, the coalescing agent coalesces a plurality of small and partially joined bubbles imparted by the foam to create larger and more discrete bubbles. A gypsum board and method of forming the slurry and the gypsum board are also disclosed. The gypsum board comprises a gypsum layer formed from the slurry. The gypsum layer defines a plurality of bubbles dispersed therein, which are imparted by the foam and coalescing agent of the slurry.

A method of digesting lignocellulosic material includes the steps of providing the lignocellulosic material and a caustic composition having a pH of at least about 10. The caustic composition includes water, an alkaline- or alkaline earth-metal hydroxide, and up to about 1 percent by weight based on a total weight of the composition of a branched digestion additive. The branched digestion additive has the structure: wherein A is at least one alkyleneoxy group and each alkyleneoxy group has from 2 to 4 carbon atoms, n is 0 or 1, B is a branched aliphatic hydrocarbon group having from 8 to 15 carbon atoms, X is H or B-0-(A), and each m is independently an average value from 3 to 30, and wherein the caustic composition has a Draves Wetting Time of less than 100 seconds as determined using ASTM D2281.

This invention is directed to amorphous and crystalline titanosilicate materials that have an unexpected selectivity for cesium and strontium, especially in the presence of high levels of competing ions. The titanosilicates of this invention show very high, unexpected selectivity in the presence of such competing cations such as sodium, calcium, magnesium and potassium, such as present in seawater.

A method of dissolving and/or inhibiting the deposition of scale on a surface of a system comprises the step of bringing the surface of the system into contact with a composition. The composition can comprise from about 3 to about 15 parts by weight of a chelating component. The chelating component is selected from the group of MGDA, NTA, HEDTA, GLDA, EDTA, DTPA, and mixtures thereof. The composition can further comprise from about 3 to about 15 parts by weight of an acidic component, which is different than the chelating component. The composition can further comprise at least about 60 parts by weight of water. Each of the parts by weight ranges above are based on 100 parts by weight of the composition. The composition may further comprise a surfactant component and/or a corrosion inhibitor.
