We have studied the conformational behavior of alpha-lactalbumin (alpha-LACT) in hydrophobic interaction chromatography (HIC). Retention characterization in terms of Z (slope of plot of ln k' vs. ln phi B, where k' is the capacity factor and phi B is the volume fraction of mobile phase B) has been explored, and the relationship of Z to other slopes, such as(More)

In this work, the irreversible processes in light heating of Silicon (Si) and Germanium (Ge) thin films are examined. Each film is exposed to light irradiation with radiative and convective boundary conditions. Heat, electron and hole transport and generation-recombination processes of electron-hole pairs are studied in terms of a phenomenological model(More)
High-performance separations of proteins, based on immobilized-metal affinity chromatography (HPIMAC), are described. The stationary phase consisted of iminodiacetic acid (IDA) chelate groups, bonded to small particle, wide pore silica gel by means of a polyether hydrophilic leash. After loading the column with metal, retention of proteins was achieved by(More)
