Desalination of seawater by spray freezing in a natural draft tower YangLiu, TingzhenMing, YongjiaWu, Renaudde Richter, YuepingFang, NanZhou Abstract The freeze-melting process can be a viable method for the purposes of desalination because of its low energy consumption, ignorable corrosion issues, and without huge pressure or membrane replacement work. Large contact area for heat and… Continue reading Desalination of seawater by spray freezing in a natural draft tower

Inhalable nanoparticulate powders for respiratory delivery Priya Muralidharan, Monica Malapit, Evan Mallory, Don Hayes Jr., Heidi M. Mansour Abstract Nanoparticles are extensively studied for drug delivery and are proving to be effective in drug delivery and the diagnostic field. Drug delivery to lungs has its advantages over other routes of administration. Inhalable powders consisting of… Continue reading Inhalable nanoparticulate powders for respiratory delivery

Impact of excipient choice on the aerodynamic performance of inhalable spray-freeze-dried powders Stefan Wanning, Richard Süverkrüp, Alf Lamprecht Abstract Spray-freeze-drying (SFD) is a process in which a solution is dispersed into a freezing medium and dried by sublimation, resulting in lyophilized powders with spherical particles. This study aims at screening and evaluating the impact of… Continue reading Impact of excipient choice on the aerodynamic performance of inhalable spray-freeze-dried powders

A nanoindentation based study to evaluate the effect of carbon nanofibers on the mechanical properties of SiC composites Shaik Mubina, P Sudharshan Phani, Asit Kumar Khanra, Bhaskar Prasad Saha Abstract An advanced high-speed nanoindentation technique is employed to analyze the combined benefit of the particulate and continuous fiber’s reinforcing effect of carbon fibers in the… Continue reading A nanoindentation based study to evaluate the effect of carbon nanofibers on the mechanical properties of SiC composites

Microstructure of spray freezing dried powders affected by the presence of inert particles Fan Zhang, Linsong Wang, Xiaoyu Ma, Qing Xu, Wei Tian, Zhanyong li Abstract Spray freeze-drying is a process to directly produce high quality powders with short drying time. The difference of microstructures has a great influence on the physical properties of powders.… Continue reading Microstructure of spray freezing dried powders affected by the presence of inert particles

Nacre-like alumina composites based on heteroaggregation Mariana Muňoz, Manuella Cerbelaud, Arnaud Videcoq, Hassan Saad, Alexandre Boulle, Sylvain Meille, Sylvain Deville, Fabrice Rossignol Abstract High strength and high toughness are usually mutually exclusive in materials. Among all material classes, ceramics exhibit a high stiffness and strength, but they present a limited plastic deformation, which results in… Continue reading Nacre-like alumina composites based on heteroaggregation

Dynamical in-situ observation of the lyophilization and vacuum-drying processes of a model biopharmaceutical system by an environmental scanning electron microscope Abstract The paper discusses the real-time monitoring of the changing sample morphology during the entire lyophilization (freeze-drying) and vacuum-drying processes of model biopharmaceutical solutions by using an environmental scanning electron microscope (ESEM); the device’s micromanipulators… Continue reading Dynamical in-situ observation of the lyophilization and vacuum-drying processes of a model biopharmaceutical system by an environmental scanning electron microscope
