Densities and kinematic viscosities of aqueous ternary solutions of 2-(methylamino)ethanol and 2-(ethylamino)ethanol with diethanolamine, triethanolamine, N-methyldiethanolamine, or 2-amino-1-methyl-1-propanol were measured at temperatures from (298.15 to 323.15) K. The total amine concentration was held constant at 50 mass %, and the (MAE or EAE)/(DEA, TEA, MDEA, or AMP) mass % ratio was varied from 0/50 to 50/0, in 10 mass % steps. The experimental values were correlated with temperature and mole fraction.

Experimental density, viscosity, speed of sound, and refractive index for binary mixtures of N-methyl-2-pyrrolidone with water, ethanol, and ethanolamine were measured over the entire composition range at different temperatures of (293.15 to 323.15) K. The effect of composition and temperature upon different physical properties has been analyzed. Excess volumes have been calculated, and their dependence on composition was mathematically represented by a Redlich−Kister-type equation.

The isolation of nanocellulose from different agricultural residues is becoming an important research field due to its versatile applications. This work collects different production processes, including conditioning steps, pretreatments, bleaching processes and finally purification for the production of nanocellulose in its main types of morphologies: cellulose nanofiber (CNF) and cellulose nanocrystal (CNC). This review highlights the importance of agricultural wastes in the production of nanocellulose in order to reduce environmental impact, use of fossil resources, guarantee sustainable economic growth and close the circle of resource use. Finally, the possible applications of the nanocellulose obtained as a new source of raw material in various industrial fields are discussed.
