Compressive Resistance

Anti-tuberculosis drugs loaded three dimensionally printed hydroxyapatite (3D printed HA) were prepared and coated with polycaprolactone to study the effect of coating on compressive resistance, microstructure, drug content and releasing characteristics. Smooth coating layer was observed on the surfaces of all coated samples while the uncoated samples displayed rough and porous surfaces. Coated samples had greater compressive resistance than uncoated samples, but the total drug contents in coated samples were slightly lower than those of uncoated ones. Both coated and uncoated samples displayed burst release of drugs initially and followed by a small release afterward. Polycaprolactone coating greatly decrease the amount of burst release of rifampicin drug loaded samples, but slightly decrease in the case of isoniazid drug loaded samples. Higher solubility of isoniazid than rifampicin in release media was thought to be the cause of limited efficiency of coating as observed.

AbstractSeveral photocatalysts, based on titanium dioxide, were synthesized by spark anodization techniques and anodic spark oxidation. Photocatalytic activity was determined by methylene blue oxidation and the catalytic activities of the catalysts were evaluated after 70 hours of reaction. Scanning Electron Microscopy and X Ray Diffraction analysis were used to characterize the catalysts. The photocatalyst prepared with a solution of sulfuric acid and 100 V presented the best performance in terms of oxidation of the dye (62%). The electric potential during the synthesis (10 V, low potential; 100 V, high potential) affected the surface characteristics: under low potential, catalyst presented smooth and homogeneous surfaces with spots (high TiO2 concentration) of amorphous solids; under low potential, catalyst presented porous surfaces with crystalline solids homogeneously distributed.
