Comparative Study on Compaction and Sintering Behavior of Spray and Freeze Granulated Magnesium Aluminate Spinel Powder Swathi Manivannan, Papiya Biswas, Prasenjit Barick, Sweety Kumari, Bhaskar Prasad Saha & Roy Johnson Abstract Commercially procured magnesium aluminate (MgAl2O4) spinel powder with average particle size of 300 nm and irregular morphology were spray and freeze granulated. The granules… Continue reading Comparative Study on Compaction and Sintering Behavior of Spray and Freeze Granulated Magnesium Aluminate Spinel Powder

Morphology of alumina granules obtained by spray freeze drying with twin-fluid atomization Ruslan Kuzmin, Sergey Veselov, Nina Cherkasova, Vladimir Bataev Abstract This study presents the results of the morphological dependence of alumina granules obtained by spray freeze drying (SFD) with twin-fluid atomization. It is shown that the introduction of 1-, 2- and 4-wt.% polyvinyl alcohol… Continue reading Morphology of alumina granules obtained by spray freeze drying with twin-fluid atomization

Combination of copigmentation and encapsulation strategies for the synergistic stabilization of anthocyanins Chen Tan, Younas Dadmohammadi, Michelle C. Lee, Alireza Abbaspourrad Abstract Copigmentation and encapsulation are the two most commonly used techniques for anthocyanin stabilization. However, each of these techniques by itself suffers from many challenges associated with the simultaneous achievement of color intensification and… Continue reading Combination of copigmentation and encapsulation strategies for the synergistic stabilization of anthocyanins

Thermolysis and Sensitivities of Nanometer Ammonium Nitrate Prepared by Ultra-low Temperature Spray Freeze Drying Method Yi Wang, Xiaolan Song, Fengsheng Li Abstract Nanometer (nano) ammonium perchlorate (AP) and ammonium nitrate (AN) were prepared with 2D network structures by the ultra-low temperature spray method. Scanning electron microscopy (SEM), X-ray diffractometry (XRD), differential scanning calorimetry (DSC) and… Continue reading Thermolysis and Sensitivities of Nanometer Ammonium Nitrate Prepared by Ultra-low Temperature Spray Freeze Drying Method

Effects of Non-covalent Functionalization and Initial Mixing Methods on SWNT/PP and SWNT/EVOH Composites Mahesh Parit, Virginia A. Davis Abstract We report that a simple, low-cost type of spray-freeze drying (SFD) significantly improves the dispersion of single-walled carbon nanotubes (SWNTs) in thermoplastic polymers. Conventional SFD requires costly specialized equipment and large amounts of material, both of… Continue reading Effects of Non-covalent Functionalization and Initial Mixing Methods on SWNT/PP and SWNT/EVOH Composites

Inhalable Protein Powder Prepared by Spray-Freeze-Drying Using Hydroxypropyl-β-Cyclodextrin as Excipient Jason C. K. Lo, Harry W. Pan, Jenny K. W. Lam Abstract The prospect of inhaled biologics has garnered particular interest given the benefits of the pulmonary route of administration. Pertinent considerations in producing inhalable dry powders containing biological medicines relate to aerosol performance and… Continue reading Inhalable Protein Powder Prepared by Spray-Freeze-Drying Using Hydroxypropyl-β-Cyclodextrin as Excipient

Spray Freeze Drying: A novel process for the drying of foods and bioproducts Padma Ishwarya S, Anandharamakrishnan Chinnaswamy, Andrew George Frederick Stapley Abstract Spray-freeze-drying (SFD) is an unconventional freeze drying technique that produces uniquely powdered products whilst still including the benefits of conventionally freeze dried products. SFD has potential applications in high value products due… Continue reading Spray Freeze Drying: A novel process for the drying of foods and bioproducts

A meticulous overview on drying-based (spray-, freeze-, and spray-freeze) particle engineering approaches for pharmaceutical technologies Abstract Drying is an indispensable operation in the preparation of pharmaceutical powders and always remained one of the energetic tasks in the pharmaceutical industry. Improving the stability, solubility, and dissolution of pharmaceutical products are being prime objectives of the drying… Continue reading A meticulous overview on drying-based (spray-, freeze-, and spray-freeze) particle engineering approaches for pharmaceutical technologies

Development and validation of an asymptotic solution for a two-phase Stefan problem in a droplet subjected to convective boundary condition Saad Akhtar, Minghan Xu, Agus P. Sasmito Abstract Droplet solidification is governed by classical Stefan problems which have been commonly treated as a single-phase problem by the majority of the studies in the literature. This… Continue reading Development and validation of an asymptotic solution for a two-phase Stefan problem in a droplet subjected to convective boundary condition
