An efficient and simple method for the preparation of 5-arylamino-1H-tetrazole and 1-aryl-5-amino-1H-tetrazole derivatives is reported using aluminum (Ⅲ) hydrogensulfate (Al(HSO₄)₃) as an effective heterogeneous catalyst from secondary arylcyanamides.Generally, when the substitution in arylcyanamide is strongly electron-withdrawing the position of equilibrium would shift toward the isomer of 1-aryl-5-amino-1H-tetrazole (B) and as the electron-donating of substituent increased, the position of equilibrium is shifted toward the isomer of 5-arylamino-1H-tetrazole (A). The present methodology offers several advantages, such as excellent yields, short reaction times, easy work-up and greener conditions.

The kinetics of aniline degradation by persulfate processes with iron (Ⅱ) activation at ambient temperature was investigated in this study. With iron (Ⅱ) as initiator, the oxidation reactions were found to follow a biphasic rate phenomenon:a rapid transformation followed by a slow but sustained oxidation process. In the first 30 s, the reaction mainly relies on the persulfate-Fe²⁺ reaction in which aniline is oxidized rapidly. After 30 s, the aniline was still oxidized but the rate of reaction tended to be slower and the rates were clearly linear-proportional. After the initial fast oxidation, the reactions appeared to follow a pseudo-first-order model.

Bamboo charcoal polyester fiber (BC-PET) has been widely applied in home textiles, functional clothing and hydra-balance material, due to their strong adsorptivity, good resolvability, anti-statics, deodorization, antibacterial, anion releasing and far infrared emitting. But BC-PET is black and difficult to be dyed, and its application is limited. In this article, nitric acid was used to treat the surface of bamboo charcoal (BC) powder, and BC powder was modified by titanium dioxide sol to prepare white bamboo charcoal (white-BC) particle. White bamboo charcoal polyester fiber (white-BC-PET) was obtained by mixing white-BC and polyester (PET) resin in double screw extruder. Performance of fiber was tested referring to national standard GB/TI4464-2008 of common PET fiber and most of its indicators have already exceeded GB the level of excellent product. SEM photographs showed that the white-BC was uniformly distributed inside or on the surface of fiber. The white-BC-PET could absorb some aniline and had at least 90% anti-bacterial rate. The anti-bacterial rate could have almost been kept after it was washed 50 times. It was hopeful to be applied in various fields as functional fiber.

It is found that different self-assembled patterns of SnO₂ nanorods can be obtained by changing the deposition conditions such as the molar ratio of CO(NH₂)₂ to SnCl₄ and the pretreatment of the substrate. Scattered SnO₂ nanorods, for example, can be changed into flower-like patterns when the molar ratio of CO(NH₂)₂ to SnCl₄ is raised, and well-aligned nanorod arrays can be formed when the pretreatment of the snbstrate is changed. In addition, some interesting patterns, e.g. tree-like patterns, can also be observed.

A membrane composed of an alginate (ALG) layer and a chitosan (CHS) layer with sustained antimicrobial efficacy was prepared. Ciprofloxacin HCI (CIP) was incorporated into the ALG layer. Morphological feature of the composite membrane was analyzed by scanning electron microscopy (SEM). Water uptake capacity, in vitro drug release, and in vitro antimicrobial activity were evaluated. The composite membrane exhibited perfect binding characteristic between the two layers. The water uptake capacity of all the membranes was above 800%. The CIP could release from the composite membranes for 48 h. The membrane could control the bacterial growth persistently. The results suggested that this CHS/ALG composite membrane incorporated with CIP had the potential for wound dressing application.
