Dispersive soils are one of the problematic such as swelling and collapsible they common in many countries world. Due to dispersive soils, significant problems arise road embankments earth dams. Therefore, use is possible with treatment. Silica fume (SF) a waste material has been used concrete production instead partially cement, stabilization expansive civil engineering applications for differ...

The biological, chemical and physical properties of dietary fibers are associated with physiologic actions in the small and large intestine that have important metabolic implications for health. These properties of fiber include dispersibility in water, bulk, viscosity, adsorption and binding of compounds and fermentability. Dietary fructans share some of the properties of dietary fiber and thu...

The potential of amphiphilic chitosan formed by grafting octanoyl chains on the chitosan backbone for pulmonary delivery of levofloxacin has been studied. The success of polymer synthesis was confirmed using FT-IR and NMR, whilst antimicrobial activity was assessed against Pseudomonas aeruginosa. Highly dispersible dry powders for delivery as aerosols were prepared with different amounts of chi...

This study focuses on the impact of whey protein/casein ratio (100/0, 79/21, 57/43, 35/65, and 12/88) physicochemical functional characteristics dairy protein powders. Spray-drying was performed in following conditions: 200 °C inlet air temperature 85 outlet temperature. Physicochemical properties (particle size distribution, shape factors, moisture content, water activity) spray-dried powders ...

Si quantum dots (SiQDs) based nanospheres (SiNSs) were prepared via a novel synthetic strategy. These SiNSs were demonstrated to possess unique dot spacing dependent photoluminescence (PL) up-conversion and surface dependent (N modified surface) down-converted PL. It was demonstrated that a small distance between SiQDs (<5 nm) is the necessary condition for the PL up-conversion of SiNSs, while ...
