the aim of the present research was to study the effects of weak cation exchange resins, polacrilex with exchangeable h+ and polacrillin potassium and strong cation exchange resin sodium polystyrene sulfonate on water uptake behavior of ranitidine hydrochloride. drug resin complexes (drc) were prepared and evaluated for the percentage of moisture gain when placed in a humidity chamber at 40e2 °...

Particles containing soot, or black carbon, are generally considered to contribute to global warming. However, large uncertainties remain in the net climate forcing resulting from anthropogenic emissions of black carbon (BC), to a large extent due to the fact that BC is co-emitted with gases and primary particles, both organic and inorganic, and subject to atmospheric ageing processes. In this ...

Deep eutectic solvents have been established as feasible metal electroplating solvent alternatives over traditional toxic aqueous plating baths. However, water, either added intentionally or unintentionally, can significantly influence the solvent’s physical properties and performance, thereby hindering its industry application. In this study, hygroscopicity, ability to absorb moisture from env...

This study aimed to determine the phenomenon during sorption on whole dried and powder butterfly pea under room temperature storage. In addition, identified thermodynamics, hygroscopicity, degree of caking, physicochemical properties quality pea. Experiments applied static gravimetric method by saturated salt at 13-27oC. The results found that best model was Peleg Model. increase in aw affects ...
