Vibrational Relaxation and Vibrational Cooling in Molecular Crystals
… and theoretically in low temperature crystals of complex molecules, specifically benzene, naphthalene, anthracene and durene. In addition to ps CARS data previously obtained on these pure crystals, the VR of dilute impurity molecules (naphthalene, anthracene) in crystalline host …

Pharmaceutical analysis and in-vitro aerodynamic characterisation of inhaled theophylline formulations containing drug particles prepared by supercritical fluid processing. Chromatographic, spectroscopic, and thermal analysis of micron-sized theophylline particles prepared by supercritical fluid technology and in-vitro evaluation of their performance as inhaled dry powder formulations.
… for the production of anhydrous theophylline as pure crystals in the range 2-5 ¿m to be used as new inhaled dry powder formulation for asthma. Fifteen theophylline samples have been prepared under different experimental conditions. The drug produced by this method has been subject to a number of …

Phonon scattering from substitutional impurities and lattice defects in cadmium sulfide
… been measured from 1.4°K to 80 0K for doped and pure cadmium sulfide single crystals of the wurtzite structure. The crystals were grown by a modified Bridgeman technique under 100 atmospheres of argon at 1100°C by the Eagle Picher Corporation. The experimental results for the pure crystals …

Chiral resolution control in batch and continuous crystallization processes for a conglomerate forming compound
… of both enantiomers) solution is seeded with pure crystals of the preferred enantiomer. Over time these crystals grow, removing the preferred enantiomer from solution whilst the unwanted enantiomer remains in solution. Given enough time, however, nucleation of the unwanted enantiomer in the …
