Synthesis and spectral characterization of a decavanadate/chitosan complex
Chitosan biomaterials vanadium compounds crosslinking
2011/4/6
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...
Inclusion and release of theophylline from chitosan based microparticles
Chitosan theophylline microparticles
2010/10/15
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...
Characterization of chitosan in acetic acid: Rheological and thermal studies
Characterization chitosan acetic acid
2010/10/14
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...
Preparation and characterization of magnetic chitosan nanospheres
Chitosan magnetite magnetic particles biocompatible
2010/4/8
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...
层层静电自组装构筑壳聚糖/磷钨酸复合膜的研究（Construction of Composite Thin Films via Layer-by-layer Electrostatic Self-assembly of Chitosan/Phosphotungstate Acid）
壳聚糖/磷钨酸复合膜 层层自组装 多层膜
2010/8/24
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...

Superabsorbency, pH-Sensitivity and Swelling Kinetics of Partially Hydrolyzed Chitosan-g-poly(Acrylamide) Hydrogels
Chitosan polyacrylamide hydrogel superabsorbent pH-reversibility swelling behavior
2010/4/19
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...
External Mass Transfer Studies during the Adsorptions of Some Dyestuffs and p-Nitrophenol onto Chitosan from Aqueous Solution
Chitosan Dyestuff adsorption External mass transfer coefficient
2010/4/20
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...
Stabilization of Papain by Modification with Chitosan
Enzyme stabilization immobilized papain chitosan
2010/4/22
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. ...
