Mussel Shells

CaO samples prepared from calcining the powdered waste shells at 1300°C for 4 h were tested the efficiency of humidity adsorption. The samples were characterized via X-ray diffraction (XRD) and Fourier transform infrared analysis (FT–IR) to identify the characteristic of CaO after humidity adsorption test. The results indicate that duck eggshells are highest capable of humidity adsorption while hydration rate of chicken eggshells is rather equal to that of cockle shells, and lowest hydration rate was found with sample prepared from Mussel shells. Therefore, we can conclude that the waste shells are suitable to be use as humidity adsorbent for commercial in the future

Effect of aeration treatment on Methylene Blue (MB) removal using TiO2-Zeolite has been investigated. The TiO2-Zeolite was prepared by mixing activated zeolite and TiO2 in absolute ethanol. This composite was characterized using Fourier Transform Infrared (FT-IR) and X-Ray Diffraction (XRD). The MB removal was monitored spectrophotometrically. The effect of contact time, composite mass, and aeration treatment on MB removal was observed. Characterization results showed that there was interaction between TiO2 and SiO/AlO of zeolite. The observation of aeration treatment using oxygen exhibited significant improving on MB removal.

Blend Films

Silk fibroin/sodium alginate blend films and its hydroxyapatite deposition were prepared and characterized by scanning electron microscopy, wide angle X-ray diffraction, Fourier transform infrared analysis, and thermal analysis. The surface of blend films showed much more rod-like structure dispersing uniformity and its average length increasing from 181 to 803nm with increasing the contents of sodium alginate. The crystal structure of silk fibroin and the compatibility of the two components were associated with the content of sodium alginate in silk fibroin/sodium alginate blend films. The silk I and silk II crystal structures of silk fibroin were co-existed in the blend films and a rather complex conformation transition occurred, which was confirmed by wide angle X-ray diffraction and Fourier transform infrared analysis. Thermal behavior of blend films was interrupted by adding different contents of sodium alginate. Adding 30.0% sodium alginate or more, the endothermic peak of moisture evaporation shifted downward from 111 to 80°C, and the degradation peaks at 243 and 279°C, respectively, indicating an obviously two phase structure in the blend films. In addition, the rod-like HAp crystals were grown on the surface of blend films. This result may provide some new ideas in the design and fabrication of new materials through the silk fibroin/sodium alginate composite materials template for the hydroxyapatite crystal growth.

AbstractNiO nanoparticles were fabricated by sol-gel route using ammonium hydroxide and nickel nitrate as precursors. The NiO nanoparticles were calcinated at 400 °C and 1000 °C. The nanoparticles were characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), vibrating sample magnetometer (VSM), thermogravimetry analysis/differential thermal analysis (TGA/DTA). The structural properties were evaluated by X-ray diffraction (XRD). XRD confirmed the formation of well-crystallized and high purity NiO phase. The XRD showed that the peaks were sharpened and the crystallite size increased as the calcination temperature increased. The average crystallite size ranged from 12 nm to 20 nm, when calcined at temperatures 400 °C and 1000 °C, respectively. Fourier transform infrared spectroscopy (FT-IR) revealed the chemical composition and confirmed the formation of NiO nanoparticles. The nanoparticles showed paramagnetic behavior.
