作者： Yanhu Guo Yumin Zhang Dabing Luo Tao Ma State Key Lab of Advanced Technology for Materials’ Synthesis and Processing Wuhan University of Technology Wuhan China

Raw ginger was introduced to a series of composite antioxidants. The specimens performed better efficiency than ordinary antioxidants while extracting vitamin C from strawberry. The results suggested that, by employing raw ginger composite antioxidant, the reservation of vitamin C could be 91.63% in washing process and 76.68% in squeezing process respectively. Furthermore, in squeezing process, the reservation of vitamin C reached 84.78% while the concentrate of raw ginger antioxidant was 0.03%. The both deposits performed perfect synergy effectively. Raw ginger composite antioxidant could be the well agent to extract vitamin C from fruit.

In this work, vertically aligned TiO2 nanorod arrays (NR) are synthesized directly on FTO coated glass substrate by hydrothermal method. The samples are characterized by XRD, SEM, TEM and the results indicate that the 1-D nanorods are of single crystal rutile structure with growth direction along the [001] direction. The morphology (diameter, thickness and density) of the nanorods can be adjusted by changing the precursor amounts. The possible growth mechanism of TiO2 nanorods on FTO substrate has also been briefly discussed in this work. For dye-sensitized solar cells (DSSCs) fabricated of different thickness nanorods, a power conversion efficiency (PCE) of 1.74% has been achieved by using ∼3 μm nanorod arrays under simulated AM 1.5 illumination (100 mW cm-2). It is expected that the 1-D nanorods can be composited with other nanomaterial of different structures and morphologies to enhance the efficiency of DSSCs. © 2016 Trans Tech Publications, Switzerland.

TiO2 thin films were prepared on soda lime glass, fused quartz and stainless steel substrates by liquid phase deposition (LPD) method from a (NH4)2TiF6 aqueous solution upon the addition of boric acid (H3BO3), and then calcined at 500°C for 2 h. The prepared films were characterized with X-ray diffraction (XRD), scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy (XPS). It was found that the substrates obviously influenced the element composition and microstructure of TiO2 thin films. Except Ti, O and a small amount of F and N elements, which came from the precursor solution, some Si (or Fe) element in the thin films deposited on soda lime glass and quartz substrates (or on stainless steel substrate) was confirmed. The Si (or Fe) element in the thin films could be attributed to two sources. One was from the SiF 62- ions (or FeF62- ions) formed by a reaction between the treatment solution and soda lime glass or quartz (or stainless steel) substrates. The other was attributed to the diffusion of Si (or Fe) from the surface of substrates into the TiO2 thin films after calcination at 500°C. The Si (or Fe) element in the TiO2 thin films could behave as a dopant and resulted in the formation of composite SiO2/TiO2 (or Fe2O3/TiO2) thin films on the substrates.

作者： Zhang, Dongming Li, Youjun Zhang, Lianmeng Guo, Jingkun State Key Lab of Advanced Technology for Materials Synthesis and Processing Wuhan University of Technology Wuhan 430070 China

Aluminum borate whiskers with TiB2 as borate source were prepared in this paper. The phase transformation process was analyzed by XRD and TG-DSC. The results indicate that TiB2 was decomposed into TiO 2 and B2O3 in the calcining process in the active [O] atmosphere. 2Al2O3.B2O3 was formed in the lower temperature with reaction of Al2O3 and B2O3, while 9Al2O3.2B 2O3 whiskers were grown by compensation of 2Al 2O3.B2O3 at higher temperature (above 1050°C).

In this study, transparent Nd: YAG ceramic was fabricated by gel casting of iso bam system using a dispersant composed of tetramethylammonium hydroxide (TMAH) to modify the rheological properties of slurry. The effects of dispersant content on the dispersibility and viscosity of slurry were studied, as well as the microstructure and light transmittance of the obtained transparent ceramics were also analyzed through the introduction of 0 − 1.5 wt.% TMAH. The results showed that the dispersion mechanism of TMAH is mainly to control the electrostatic property and the alkaline Zeta potential value of the slurry. The electrostatic repulsion of ceramic particles in the slurry could be effectively increased through the dispersing action of the additive, thereby reducing the viscosity of the slurry and improving the fluidity of the slurries. Under the TMAH content of 1 wt.%, a high-fluidity and good dispersion of Nd: YAG slurry with a solid load of 78.8 wt.% was obtained. A low viscosity of 72.89 mPa·s was achieved under shearing of 100 s-1, and a dense uniform body was obtained by self-gelling reaction. Highly transparent Nd: YAG ceramics were obtained after vacuum reaction sintering at 1780°C for 10 h, with a transmittance of 75.12% at 1064 nm. In all, the TMAH dispersant could effectively improve the molding properties of PIBM single system gel injection molding transparent ceramics. © 2022 SPIE.
