“…The primary requirement of nitric acid is in the fertilizer industry for the production of ammonium nitratea critical fertilizer . Nitric acid is also used in a variety of other applications like the production of nitrobenzene, adipic acid, toluene diisocyanate, and similar organo-nitrates. Apart from these conventional requirements for nitric acid, one major requirement comes from nuclear industries.…”

Different concentrations of nitric acid are routinely used in various steps of the nuclear fuel cycle in both the front and back ends. The physical properties of nitric acid−water mixtures are essential to design solvent extraction equipment used in nuclear fuel cycle. However, apart from density, comprehensive information about other physical properties (e.g., viscosity) is lacking. This work addresses this gap area. Four different physical properties�density, viscosity, speed of sound, and refractive index�of different concentrations of nitric acid in water (w f = 0−0.490) are reported for different temperatures (5−50 °C).Empirical correlations have been developed to represent the data set generated. The effect of nitric acid concentration on the speed of sound is really interesting. At lower temperatures, the speed of sound increases nonlinearly with an increase in concentration, while at higher temperatures, the trend is reversed. There is an inflection point at around w f = 0.275 nitric acid concentration where the plots tend to converge. Such insights are reported for the first time. Derived thermoacoustic variables (isentropic compressibility, intermolecular free length, acoustic impedance, molar speed of sound, and molar compressibility) for a nitric acid−water mixture have also been computed and reported, once again for the first time. Furthermore, a comparison of all physical properties of fresh and equilibrated nitric acid/water mixtures (with 35.73 wt % TBP in dodecane) is also reported.

“…Modifying synthetic polymers using carbohydrate derivatives enables tuning the properties of the resulting polymers, including their biodegradability and biocompatibility, [ 1 ] resulting in more environmentally friendly alternative polymer products. Carbohydrate-modified polymers have applications in clinical diagnostics for targeted gene therapies and prosthetic uses [ 2 , 3 ], drug delivery systems, tissue engineering, dental applications, contact lens materials and bioimplants [ 4 ].…”

The synthesis of glycopolymers by copolymerising an allyl glucosamine (AG) monomer with co-monomers methyl methacrylate (MMA), acrylonitrile (AN) and 2-hydroxyethyl methacrylate (HEMA) was investigated via free-radical polymerisation of 2,2-azobisisobutyronitrile (AIBN) in dimethylformamide (DMF). Three new copolymers, poly(AG- co -MMA), poly(AG- co -AN) and poly(AG- co -HEMA), were obtained. The chemical structures of the glycopolymers were analysed using 1 H-NMR, 13 C-NMR and FTIR. The thermal properties and degradation kinetics of the three glycopolymers were examined by thermogravimetric (TG) analysis at different heating rates. The effects of different co-monomers on the copolymerisation yield, thermal properties and biological activities of the resulting glycopolymers were investigated. The activation energies of the decomposition stages were calculated using the Flynn–Wall–Ozawa (FWO) and Kissinger methods. Furthermore, the biological activity of AG monomers and glycopolymers was studied and compared to chitosan. Poly(AG- co -HEMA) had the most significant effect on MCF-7 cell viability, and all glycopolymers have a low toxic effect profile on MCF-7 cell lines.
