Novel Method

Engineering and decoration on the surface of metal oxide semiconductor (TiO2) for increasing activity is challenging. Thus a novel method is introduced to determine surface morphology quality subsequently improving the photocatalytic behaviour. TiO2films are fabricated via laser deposition technique at various CdS thickness. Microstructural characterization and optical behaviours are characterized by felid emission scanning electron microscope (FE-SEM) and atomic force microscope (AFM). The hydrophilic property of TiO2/CdS nanocomposite film (NCF) is examined via contact angle measurements. The grain density is found linearly increased with the contact angle. A mutual relationship is revealed between hydrophilic property and crystallization with respect to the CdS thickness. Thus, surface morphology of nanocomposite quality is quantified based on the hydrophilic measurement

Lower Contact

Crystalline hydroxyapatite (HA) and 0.8 wt.% silicon-substituted HA (SiHA) thin films were produced using magnetron co-sputtering. These films were subjected to contact angle measurements and in vitro cell culture study using human osteoblast-like (HOB) cells. A wettability study showed that SiHA has a lower contact angle, and thus is more hydrophilic in nature, as compared to HA. Consequently, enhanced cell growth was observed on SiHA at all time-points. Furthermore, distinct and well-developed actin filaments could be seen within HOB cells on SiHA. Thus, this work demonstrated that the surface properties of the coating may be modified by the substitution of Si into the HA structure.
