In this work, n-ZnO/p-CuxO and n-Cu:ZnO/n-Zn:CuO core-shell nanorod (NR) arrays were synthesized by depositing CuxO nanoshells with different thickness on surface of ZnO NRs and subsequent annealing. Scanning electron microscopy (SEM) and Transmission electron microscopy (TEM) show the outer CuxO shells were comprised of Cu2O and CuO nanocrystals before annealing, but they transformed to single-crystalline...
Studies on cellular behaviors on substrates with various physicochemical properties have important implications in cytology and bio-medical field. And a variety of cell microarrays have been developed to study in vitro. Our study aims to explore the relations between nano silicon dioxide structure substrates and circulating tumor cells (CTCs) adhesion, and create cell microarrays based on the cell...
This paper demonstrates a dental pulp cell therapy method by using a mixture of a bioceramic materials, simvastatin and collagenase as a drug delivery bioceramic diluent. The drug releasing mechanism and speed are based on a natural diffusion of concentration differences and micro-pinhole sizes on the bioceramic cement, which is composed of the calcium phosphate cement (CPC) and calcium sulfate dihydrate...
Poly(ethylene glycol) diacrylate (PEGDA) are being investigated for various tissue engineering applications for its biocompatibility and excellent mechanical properties. However, the native PEGDA films can hinder cell adhesion which limits applications in the field of tissue engineering and biomedicine. Recently, nano composite technology has been a particularly hot topic because of it can be used...
Two types of gold-supported TiO2 catalysts (anatase and rutile) were prepared using a deposition precipitation method, and their photocatalytic activity towards CO2 reduction was tested in the gas phase using H2O as an electron donor and a xenon lamp as the energy sources. The crystal structures were verified using a scanning electron microscope (SEM) and the loaded Au nano-particles (NPs) had no...
Lead telluride (PbTe) thin films have been deposited on SiO2 substrate using thermal evaporation method. The structure of the films was found to have a face-centered cubic (fcc) with predominant grain growth in the (200) direction for both as-deposited and annealed samples up to 350 °C in vacuum for 1 h. The in-plain electrical resistivity and Hall measurements via van der Pauw method as a function...
Polycrystalline diamond (PCD) films prepared by chemical vapor deposition (CVD) can improve surface properties of hard materials. In this study, the growth rates of PCD film prepared by hot-filament CVD have been investigated on the influence of CH4 concentration. Tribological properties of PCD films on sintered SiC substrates were investigated for application on the mechanical seals of pumps. The...
Poly(vinylidene fluoride) (PVDF) is a biocompatible polymer commonly used for biomedical applications, food packaging and hygiene products. Within these contexts, the polymer surface is typically exposed to microorganisms and bacteria, with consequent biofilm formation. In this paper, self-standing flexible composite poly(vinylidene fluoride)(PVDF) films with antimicrobial properties were prepared...
