Formation and Stability of Polyelectrolyte Multilayers of Chitosan and Poly(acrylic acid) Liu Bingtao1, a, Remco Fokkink2,b, Arie de Keizer2,c 1North China institute of water conservancy and hydroelectric power, ZhengZhou , China 2Laboratory of Physical Chemistry and Colloid Science, Wageningen University, The Netherlands aemail: liubingtao@ncwu.edu.cn, bemail: Remco Fokkink@wur.nl, cemail: Arie.deKeizer@wur.nl Keywords: chitosan, poly(acrylic acid) , multilayer, reflectometry , stability Abstract..
Chitosan is composed of β(1-4) linked glucose amine units with part of the amino groups acetylated.In solution chitosan adopts a flexible coil-like structure,and aggregation is sensitive to both pH and degree of acetylation.The amino group in chitosan has a pKa value of -6.5, thus,chitosan is positively charged and soluble in acidic to neutral solution.

Pretreating the fly ash with an alkali solution decreases the adsorption capability, possibly by destroying the zeolite structure.
Unlike the untreated fly ash, both types of modified fly ash do not form new zeolite structure, and the mullite and calcium-based zeolite contents decrease.
Zeolite structure formed by Ca (CO3) and other minerals can promote adsorption. 
(2) Acid-modified and alkali-modified fly ash cannot form new phases of zeolite structure, and the contents of mullite and the calcium-based zeolite structure phases were decreased.

Similarity of deuterium absorption at room temperature for different Ti-Zr-Ni quasicrystals Huogen Huang 1, a, Rong LI 1,b and Liang CHEN 2,c 1 Science and Technology on Surface Physics and Chemistry Laboratory, P.O.Box 718-35, Mianyang 621907, Sichuan, China 2 China Academy of Engineering Physics, P.O.Box 919-71,Mianyang 621900, Sichuan, China ahhgeng2002@sina.com, bjunping-li@sohu.com, cchenlianglinyu@gmail.com Keywords: Quasicrystal; Deuterium absorption; Alloy; Ti-Zr-Ni.
In fact, these three quasicrystals should have similar interstitial quantity resulting from the same Bergman-typed structures and similar compositions.
The alloy phase structures were examined by a Y-2000 typed X-ray diffractometer (XRD) with Cu Kα radiation.
Finally, the samples turned into powder, whose phase structures were examined by using the XRD technique.
With regard to similar structure and composition, we consider that Ti-Zr-Ni quasicrystals should have close hydrogen/deuterium absorption properties.
