Solution Precursor Plasma Spray (SPPS) technique is an emergent technique which offers significant performance advantages with various functional coatings like YSZ, ZnFe2O4, LSM, metal-doped ZnO, etc. Apart from the above capabilities, efforts towards development of an innovative hybrid approach through simultaneous deposition of powder and solution resulted in coatings with unique microstructu...

Thermal sprayed surface coatings are extensively used for a wide range of industrial applications. In the plasma spray process used in thermal spraying, the temperature of substrate and conduction of heat along the thickness of ceramic oxide coatings (TCOC) play an important role in the bond strength and microstructure of the coatings, which decides its performance and quality. In this study, u...

We present a technique for fabricating hydrophobic drug nanoparticles using a microfluidic spray dryer. The nanoparticles are formed by evaporative precipitation of the spray in air at room temperature. Using danazol as a model drug, amorphous nanoparticles are yielded with narrow size distribution, 20-60 nm in diameter. As the device geometry allows us to inject two separate solvent streams, t...

The pharmacokinetics of spray dried composition (1:1 PAL: K12) and pure PAL was evaluated following oral administration (0.8 mg/kg) in healthy female Sprague Dawley rats. The extent of the mean plasma exposures of PAL was 11-fold higher in animals treated with spray dried mixture of PAL, K12 (1:1) compared to animals treated with PAL. Spray drying of PAL with Plasdones, especially Plasdone K12,...

Droplet transport processes that occur in fuel sprays and spray flames were examined using laser velocimetry, phase Doppler interferometry, and laser sheet beam photography. Droplet size and velocity (axial and radial) distributions were obtained in a swirl-stabilized, pressure-atomized kerosene spray under nonburning and burning conditions. The results show that the introduction of swirl to th...

Plasma concentrations of lignocaine were measured in three groups of anaesthetized patients following spraying of the trachea and larynx with a lignocaine 10% aerosol spray. Greater venous plasma concentrations occurred in patients who were paralysed with suxamethonium. A mean plasma concentration of 0.1 mug/ml of lignocaine resulted from each 10 mg of lignocaine used in spontaneously breathing...

Conventional and nanostructured YSZ coatings were deposited on the IN-738 Ni super alloy by the atmospheric plasma spray technique. The oxidation was measured at 1100°C in an atmospheric electrical furnace. According to the experimental results the nanostructured coatings showed a better oxidation resistance than the conventional ones. The improved oxidation resistance of the nanocoating could ...
