Chirality‐Assisted Ring‐Like Aggregation of Aβ(1–40) at Liquid–Solid Interfaces: A Stereoselective Two‐Step Assembly Process†

Molecular chirality is introduced at liquid–solid interfaces. A ring‐like aggregation of amyloid Aβ(1–40) on N ‐isobutyryl‐ L ‐cysteine ( L ‐NIBC)‐modified gold substrate occurs at low Aβ(1–40) concentration, while D ‐NIBC modification only results in rod‐like aggregation. Utilizing atomic force microscope controlled tip‐enhanced Raman scattering, we directly observe the secondary structure information for Aβ(1–40) assembly in situ at the nanoscale. D ‐ or L ‐NIBC on the surface can guide parallel or nonparallel alignment of β‐hairpins through a two‐step process based on electrostatic‐interaction‐enhanced adsorption and subsequent stereoselective recognition. Possible electrostatic interaction sites (R5 and K16) and a chiral recognition site (H14) of Aβ(1–40) are proposed, which may provide insight into the understanding of this effect.

Slow Photon Enhanced Photocatalytic Activity of ZnO Inverse Opal Film Synthesized by Sol-gel Method

International Conference on Nanoscience & technology,China 2013(ChinaNANO 2013)

作者： Jing Liu Jun Jin Shao-zhuan Huang Li Wang Chao Wang Yu Li Bao-lian Su Laboratory of Living Materials at State Key Laboratory of Advanced Technology for Materials Synthesis and Processing Wuhan University of Technology Laboratory of Inorganic Materials Chemistry (CMI) The University of Namur (FUNDP) Department of Chemistry University of Cambridge

Recently, inverse opal structures, which have many potential applications in catalysts, separations, sensors, bioscience and photonics for their unique advantages such as highly ordered pore structure, large specific surface areas. The common synthesis strategy for inverse opal films is colloidal crystal templating method. This method included three steps: (1) synthesizing the hexagonal ordered-closed colloidal crystals;(2) immersing the liquid mental precursor into the voids of the templates;(3) removing the templates by calcination or etching. Several fabrication methods for ZnO inverse opal film synthesis have been reported including atomic layer deposition, chemical vapor deposition and electrodeposition. However the large-scale ZnO inverse opal film synthesized by sol-gel method has seldom been reported and the mechanism on the photocatalytic activity of ZnO inverse opal film is still needed to be explored. In this work, different sizes of P(St-MMA-SPMAP) colloidal spheres were used as templates and Zn(NO 3 ) 2 as precursor to obtain the ZnO inverse opal film. The products have been characterized by XRD, SEM, and UV/Vise spectrometer. The morphology of the products is highly organized, dense and large-scale and the crystalline of the products is hexagonal wurtzite structure. The different sizes of ZnO inverse opal films have been applied for the photodecomposition of the rhodamine B (RhB) in water. Through the results it can be concluded that the photocatalytic activity has been correlated with the pore sizes of the ZnO inverse opal film, which ascribe to the slow photon effect. When the stop-band edge matches the irradiation wavelength, it can increase the path length of light by enhancing the light absorption of the material resulting in enhanced photocatalytic activity.

Crystallization kinetics of mullite from single-phase gel

Gongneng Cailiao/Journal of Functional Materials 2013年第24期44卷 3571-3575页

The crystallization kinetics of mullite from single-phase gel were studied using a non-isothermal thermal analysis method. The microstructure changes were investigated by X-ray power diffraction (XRD), transmission electron microscopy (TEM) and 27Al nuclear magnetic resonance (NMR) spectroscopy. The results show mullite crystallization begins from 950°C. The crystallization process confroms to random nuclei production and the following unclei growth model of n-dimension Avrami-Erofeev. The activation energy Ea and the pre-exponential factor A of mullite crystallization are 1086.34 kJ/mol and 9.33×1042 s-1, respectively. The differential expression of the corresponding mechanism function was f (α) =n(1-α)[-ln(1-α)]n-1/n, n= 3.37. The nucleation rates are non-uniform which decrease with the time t in crystallization process. Nucleation was the dominant controlling step at about 980°C. Nucleation-growth becomes more predominant at about 1000°C. The rates of the grain growth are controlled by diffusion.
