The prediction of cellulose acetate membrane characteristics by recent phenomenological models
%, the morphological
structure of membranes changed from sponge-like to finger-like. Results showed that the common
thermodynamic and kinetic parameters of membrane formation could not predict the proportion
of solvents in which the primary...
PVC membranes from PVC/Water/THF and PVC/Water/DMF systems, a comparative study
In this paper an analysis is presented, which describes membrane formation from PVC/water/THF and PVC/water/DMF systems. A simple mathematical model is used to investigate kinetic aspects of membrane formation coupled with system thermodynamics...
Ground reaction forces in shallow water running are affected by immersion level, running speed and gender

A Facile Synthesis of (S)-(-)- Propranolol
A one-pot synthesis of (S)-(-)-propranolol is reported. Zn(NO3)2/(+)-tartaric
acid catalyzed enantioselective synthesis of (S)-(-)-propranolol via kinetic
resolution of key intermediate α-naphthyl glycidyl ether with high optical and...
Accommodating of resolved chemical kinetic model of uncalibratedinterferents during multivariate calibration models
The simultaneous determination of several analytes based on kinetic spectrophotometric method is usually performed by chemometrics method, especially in cases where the analytes react with a common reagent. One of the most serious problems...
Preparation of Polyvinylchloride Membranes from Solvent Mixture by Immersion Precipitation
In this study, polyvinylchloride (PVC) membranes were prepared through the immersion precipitation method using a mixture of two solvents (tetrahydrofuran (THF) and dimethyl formamide (DMF)), which had different affinities ...
