TLDR
In this paper, the Apelblat model showed a good correlation in both solvent systems, the best predictive fit model, and the experimental results were compared with a correlative thermodynamic model, three activity coefficient models (Wilson, UNIQUAC, NRTL), and with literature data.About:

Hydrogen bonding interaction of ascorbic acid with nicotinamide: Experimental and theoretical study
TL;DR: In this article, the interactions of ascorbic acid (AA) with nicotinamide (NA) were investigated by cyclic voltammetry (CV), 1H nuclear magnetic resonance (1H NMR), density functional theory (DFT) and atoms in molecules (AIM) analysis.

Solid-liquid equilibrium of paracetamol in water-ethanol and water-propylene glycol mixtures
TL;DR: In this paper, the authors determined paracetamol solid-liquid equilibrium in temperatures from 20 to 50°C for two solvent systems: water - ethanol and water - propylene glycol (PG), by refractometry method.
