Synthesis of Carboxymethyl Starch with High Degree of Substitution by a Modified Dry Process Sifang Lia, Jean Marie Vianney Mujyambereb and Miao Liuc Department of Chemical and Biochemical Engineering, College of Chemistry and Chemical Engineering, Xiamen University, Xiamen 361005, China asfli@xmu.edu.cn, bjean10484@gmail.com, cliumiao905@126.com Keywords: Carboxymethyl starch, Potato starch, Sodium monochloroacetate Abstract.
Alkaline treatment is responsible for the changes in the granular structure of CMS.
It is possible that the changes observed on the starch granules are due to the loss of crystalline structure affected by strong alkaline conditions.

The adhesion and peel phenomenon between asphalt and aggregate is a very complex physic-chemistry-mechanic process, affected by many factors, such external conditions as asphalt chemical composition and structure, aggregate mineral component and structure, moisture and temperature. 2　Evaluating methods of adhesion For asphalt pavement, good water stability and durability depend on firm connection between asphalt and aggregate without scaling.

Carbon nanotube (CNTs) has good quality as the special structure, which is thought to be the ideal addition for PU composites [2].
Currently, the method to improve the dispersion of CNTs in PU substrate mainly have physical blending, in situ polymerization and chemistry modification [6].
It can not meet the demand of dispersion with too small ultrasonic power, and the long diameter ratio even the structure of CNTs are impacted with too great ultrasonic power.

Effect of Iron (III)-Doping on the Photocatalytic Activity of Titanium Dioxide Catalysts for Methylene Blue Degradation Wen-Churng Lin1, a, Rui Liu2, b, Wein-Duo Yang3, c 1Department of Environmental Engineering, Kun Shan University, Tainan 710, Taiwan 2 Department of Applied Chemistry, Harbin Institute of Technology, Harbin 150001, PR China 3Department of Chemical and Materials Engineering, National Kaohsiung University of Applied Sciences, Kaohsiung 807, Taiwan a linwc@mail.ksu.edu.tw, b liurui19840601@yahoo.cn, c ywd@cc.kuas.edu.tw Keywords: Iron-doped TiO2, Sol-gel, Visible light, Photocatalytic Abstract.
The well-known method to prepare metal ions doping TiO2 is based on the sol–gel process, which has advantages of flexible control of pore structures and dopant concentration and a high level of chemical purity.
Fe3+-doped TiO2 photocatalyst powders were prepared by sol-gel route using titanium tetraisopropoxide (TTIP) and ferric nitrate as the precursors, iso-propanol (IPA) as the solvent, acetylacetone (AcAc) as the stabiliser, polyethylene glycol (PEG) as the structure-directing agent, and hydrochloric acid (HCl) as a catalyst.

As a result, PCA retains the relationship structure among process variables, in accordance with data acquisition degree of variation, this scheme is optimal.
In (4), sample matrix reflects the associated structure of covariance matrix.

Introduction The D-A type molecules have attracted much academic and technological research attention during the past decade because of their great potential applications as photoactive materials in molecular electronics, such as biochemical fluorescent technology,1 electrogenerated chemiluminescence,2 organic light emitting diodes (OLEDs),3 and photovoltaic cells.4 Compared to other materials, the donor-acceptor materials have an advantage on their physical properties easily being tuned over a wide range by appropriate chemical modification to the structures of donors or acceptors.5 Recently, Donor-acceptor (D-A) molecules are of great interest as light-emitting and electroluminescent multifunctional materials for organic light-emitting diodes (OLEDs).6 To make a improvement of the property of OLEDs, the feature of emissive materials we desired should be highly capable of accepting both electrons and holes while exhibiting high luminescence quantum yield.7 That’s to say, we should explore
The fluorescence spectra of the compound 3 have well-resolved vibronic structures in dilute THF solutions and in the solid states, as shown in Fig. 2b.

Introduction Catastrophic fracture failure of engineering structures is caused by cracks that extend beyond a safe size.
The fundamentals postulate of linear elastic fracture mechanics is that the crack behavior is determined by the stress intensity factors, which are the function of the applied load and the geometry of the cracked structure.
