摘要： A visibly transparent, homogeneous UV-blocking cellulose nanocrystal/lignin nanocomposite film and a method of making the same. The film is made by dispersing cellulose nanocrystals and lignin in an aqueous, alkaline solution to yield a dispersion; casting the dispersion onto a substrate; and evaporating the aqueous, alkaline solution to yield a homogeneous, visibly transparent film that at least partially absorbs ultraviolet (UV) radiation.

摘要： A method of making a binder for extruded, pelleted, or agglomerated animal feed. The binder is made by treating biomass such as soybean hull or lemon peels with an aqueous acidic solution for a time, at a temperature, and at a pH sufficient to yield a first mixture containing biomass solids and partially dissolved biomass; and mechanically treating the first mixture of step to yield a first mechanically treated mixture; and then incorporating the first mechanically treated mixture as a binder in an animal feed. Also described are animal feeds made using the binder.

摘要： A device for detecting volatile compounds. The device includes a substrate and a matrix disposed on the substrate. The matrix includes a carboxyl-rich binder, a clay, and a pH-sensitive indicator dye admixed with the binder and the clay. The pH-sensitive indicator dye is dimensioned and configured to change color in response to contact with a pre-determined concentration of a volatile compound.

摘要： Described is a method of kraft pulping in which a phenolic compound is added to the cooking step. The phenolic compound is added at a time point between about 5 minutes and about 120 minutes prior to completion of the cooking step. The presence of the phenolic compound increases the extent of delignification in the cooking step.

摘要： An integrated process and corresponding apparatus that produces a relatively clean, delignified cellulose product from lignocellulosic biomass. The method includes treating a portion of the delignified cellulose itself as a substrate to produce on-site cellulolytic enzymes, including further treating the remaining delignified cellulose with the resulting cellulolytic enzymes for in situ enzymatic hydrolysis. The process and apparatus are useful to produce fermentable sugars for cost-effective manufacturing of fermentable sugars, fuels, bioproducts and chemicals.
