A decavanadate/chitosan complex was synthesized by crosslinking chitosan with decavanadate anions at a pH of 3. The materials were characterized by Fourier transformed infrared spectroscopy (FT-IR), X...
Chitosan (CS) based microparticles for controlled release of theophylline (THP) were obtained by ionic gelation. The microparticles were characterized by laser diffraction analysis (particle size), sc...
This study examined the influence of temperature, concentration, shearing time, and storage time on the rheological properties, i.e. the dynamic viscosity and shear stress, as a function of shear rate...
A method for the preparation of magnetite/chitosan composite nanoparticles was developed. Colloidal magnetite particles (Fe3O4 produced by co-precipitation and stabilized in suspension by adding a non...
将正电荷的壳聚糖与负电荷的磷钨酸溶液通过静电作用交替沉积在基底上组装复合多层膜。使用紫外可见光谱(UV-Vis)、红外光谱(FTIR)、X-射线光电子能谱(XPS)、原子力显微镜(AFM)和循环伏安法(CV)等手段对复合膜进行了表征。UV-Vis结果显示多层膜在特征吸收峰处的吸光度数值随膜双层数增加逐渐增大,呈良好的线性关系,表明多层膜是均匀组装的;XPS和FTIR结果证实了壳聚糖和磷钨酸被组装到...

期刊信息 篇名 Abnormal fluorescence behavior of pyrene functionalized chitosan films to some quenchers 语种 英文 撰写或编译 作者 张淑娟,房喻,胡道道,高改玲 第一作者单位 刊物名称 Chin. J. Chem 页面 2003, 21: 249-252 出版日期 2003年 月 日 文章标识(ISSN) ...
Acrylamide (AAm) monomer was directly grafted onto chitosan using ammonium persulfate (APS) as an initiator and methylenebisacrylamide (MBA) as a crosslinking agent under an inert atmosphere. Two fact...
The effect of temperature on the adsorptions of some dyestuffs [orange II (O-II), crystal violet (CV) and reactive blue 5 (RB5)] and an ideal adsorbate p-nitrophenol (PNP) by chitosan (Sigma C 3646) f...
Papain (EC 3.4.22.2) was immobilized on chitosan by adsorption and subsequent cross-linking with glutaraldehyde. The immobilized papain displayed a lower specific activity than did the native enzyme. ...
