The purpose of this research was to study the aqueous-based film coating of tablets utilizing a laboratoryscale side-vented perforated pan-coating apparatus. The process parameters of potential importance with respect to the final film quality were evaluated by using trial and error method. Tablets were evaluated for coating uniformity (mg), coating process efficiency (%), surface roughness, an...

Europium-doped yttrium silicate (Y2SiO5:Eu ) nanophosphors were successfully synthesized by flame spray pyrolysis method. The effect of silicon concentration on the crystal structure and morphology of the Y2SiO5:Eu 3+ phosphors were investigated. Asprepared phosphor consists of spherical nanoparticles with filled morphology, high crystallinity, narrow size distribution, and intense photolumines...

Cold spray coatings are considered promising for surface protection of light metal substrates but the mechanisms of bonding and coating build-up are still poorly understood and are the subject of continuing debate. A variety of coating/substrate combinations have been characterised in detail using electron microscopy to examine the nature of the interparticle and particle/substrate interfaces. ...

Abstract Impact spreading of droplets in spray coating of paper was investigated using numerical simulation based on a volume-offluid (VOF) model. The results include the effects of droplet size, droplet impact velocity, liquid viscosity, liquid surface tension and paper web velocity on droplet spreading. Pressure and strain rate fields as well as timescales of spreading are reported. The resul...

Flame Spray Pyrolysis (FSP) is a well investigated high temperature aerosol technique for synthesizing nano-sized metal oxide catalysts of almost all metals and transition metals by gas-to-particle conversion (Teoh et al. 2010). However, specific designs of multi-component catalysts and the controlled dispersion of catalytic material on the support are limited with this approach. Double Flame S...

Transition metal fluorides (such as FeF3 or CoF2) promise significantly higher theoretical capacities (>571 mAh g(-1)) than the cathode materials currently used in Li-ion batteries. However, their practical application faces major challenges that include poor electrochemical reversibility induced by the repeated bond-breaking and formation and the accompanied volume changes and the difficulty o...

Manganese oxide (MnO 2 ) microspheres are prepared using an ultrasonic spray pyrolysis (USP) process. A mixed solution of potassium permanganate and hydrochloric acid is nebulized into microsized droplets, which are then carried by air fl ow through a furnace tube. Each microdroplet serves as one microreactor and produces one microsphere. Upon heating, KMnO 4 is decomposed into MnO 2 microspher...

Nanocomposite thin film deposited on copper and glass substrates have been created by utilizing Spray Pyrolysis method. The prec...

A nanostructural hydroxyapatite (HA) coating was deposited to the porous Ti6Al4V acetabular cup implants using a room temperature electrophoretic deposition (EPD) process in order to achieve the improved bonding strength between the implants and cells, fast healing, good corrosion resistance and long-term stability after implantation. The micropores created in the coating will improve the bioac...
