The Spray-drying of Ammonium Perchlorate by Ultrasonic Comminution.

The Role of Boron in Thermal Decomposition of Ammonium Perchlorate

Simultaneous thermal analysis (STA) method has been applied to study decomposition reactions of AP under a flowing nitrogen atmosphere and static air. Results obtained indicate that a phase transformation occurs prior to the decomposition reaction. Decomposition takes place exothermally in two stages, first stage of decomposition could be suppressed by the controlled heating programme. Addi...

Challenges of Probiotics Microencapsulation by Spray Drying Method

Introduction: In the recent years, attention to the use of probiotic drugs and probiotic food products, due to probiotic’s functional and health properties has been increased. The storage and the viability of the probiotics in the products and passing through the gastrointestinal tract was always a big challenge. Drying is one of the functional and important choices that can be used for stabili...

Optimization of Lycopene Microencapsulation by Spray Drying

The objectives of this work were to develop a new technique for lycopene microencapsulation by spray drying using dehumidified air as drying medium and to determine optimum operating conditions. A two-step optimization procedure was used. The encapsulation variables were selected in accordance with the PlackettBurman experimental design and were further optimized via response surface methodolog...

Effects of Spray Drying and Spray Chilling on Ibuprofen Dissolution

       The formulation of hydrophobic drugs for oral drug delivery is challenging due to poor solubility, poor dissolution and poor wetting of these drugs. Consequently, the aim of this study was to improve the dissolution of a model poorly water soluble drug, ibuprofen. Microparticles containing ibuprofen were produced by spray drying and spray chilling technology in the absence/presence of a ...
