Abstract In this work, characterization and kinetics of CO2 absorption in potassium carbonate (K2CO3) solution promoted by diethylenetriamine (DETA) were investigated. Kinetics measurements performed using a stirred cell reactor the temperature range 303.15–323.15 K total concentration up to 2.5 kmol m?3. The density, viscosity, physical solubility, diffusivity rate determined. reaction between...
An in vivo investigation of paracetamol availability was carried out on eight healthy volunteers, comparing two paracetamol suppository formulations prepared using two different gliceride bases, a fast drug-releasing one and a slow drug-releasing one, i.e. Witepsol H15 and W35, respectively. The formulations were selected on the basis of a previous in vitro drug release study, which showed that...
The absorption by roots of ions in general, and phosphate absorption in particular, can occur against concentration gradients so great as to require free energy changes of the order of 8,000 calories per nmole. This implies coupling in the absorption process with reactions Jeroceecling wdith considerable free energy decrease. Few reacticius in plants other than those for production or destructi...
Table S1. Transient decays of the excited state absorption of the singlet excitons of the polymers studied. Multiple single wavelength decays are plotted to improve the quality of the data fitting and avoid complications from spectral inhomogeneity. The experimental data is included as scatter points. The solid lines represent exponential fits to the data. The kinetics of BTT-DPP, DPP-TT-T, SiI...
