Deliquescence in Urea and Methyl-ureas [PDF]
Nature, 1940 A COMMUNICATION in NATURE from E. A. Werner1 directed attention to the deliquescence of urea and to the paucity of data concerning the vapour pressures of saturated solutions of urea and its derivatives, apart from the few observations of Adam and Metz2, and Edgar and Swan3.

Hydration of urea and alkylated urea derivatives
The Journal of Chemical Physics, 2018 Compressibility data and broadband dielectric spectra of aqueous solutions of urea and some of its alkylated derivatives have been evaluated to yield their numbers Nh of hydration water molecules per molecule of solute. Nh values in a broad range of solute concentrations are discussed and are compared to hydration numbers of other relevant molecules ...

Hydrogen from urea: a novel energy source [PDF]
, 2011 This research presents a viability assessment of using urea as an energy vector. Urea is attractive in comparison to the chemicals previously considered for supplying hydrogen since it is non-toxic, non-flammable and stable at room temperature and ...

Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Introduction Patients requiring long‐term continuous renal replacement therapy (CRRT) generally have poor prognoses. This study evaluated whether adding continuous intravenous sodium infusion (cIVNa) is associated with improved hemodynamics and outcomes in patients undergoing long‐term CRRT for ≥ 7 days.
