In this study, the electrospun silk fibroin nanofibrous scaffolds were modified with heparin by grafting after plasma treatment and blending electrospinning. Morphology, microstructure, chemical composition and grafting efficiency of the heparin-modified silk fibroin nanofibrous scaffolds were characterized to evaluate the effect of modification by means of scanning electron microscopy (SEM), Fourier transform infrared spectra (FTIR) and X-ray photoelectron spectrometer (XPS). The results showed that the heparin was successfully introduced to the silk fibroin nanofibrous scaffolds by both the two kinds of modification, and there was a hydrogen bonding between the silk fibroin and heparin. Moreover, the hydrophilicity, O-containing groups and negative charge density of the heparin-modified scaffolds were enhanced. In vitro coagulation time tests showed that the activated partial thromboplastin time (APTT), prothrombin time (PT) and thrombin time (TT) of the heparin-modified scaffolds were much higher than those of the pure silk fibroin scaffolds. L929 fibroblasts and EVCs spread and proliferated better on the heparin-modified scaffolds than on the pure silk fibroin scaffolds. Macrophages, neutrophils and lymphocytes were not observed in the heparin-modified scaffolds, which indicated that the modified scaffolds could induce minor inflammation in vivo. The results indicated that the electrospun heparin-modified silk fibroin nanofibrous scaffolds could be considered as ideal candidates for tissue engineering scaffolds. © 2010 Elsevier B.V.

Iodine-catalyzed intermolecular dehydrogenative aromatizations of six-membered cyclohexanones for the selective synthesis of 2-sulfanylphenols have been developed. Both aryl and alkyl disulfides can be used as sulfanylation reagents to give the desired products in good yields under the optimized reaction conditions. The catalytic reaction uses dimethyl sulfoxide or oxygen as the terminal oxidant and avoids the use of transition metal catalysts. In addition, a-sulfanyl enones could also be obtained via an iodine-catalyzed oxidative system from simple cyclic ketones using dimethyl sulfoxide as the oxidant. © 2013 Wiley-VCH Verlag GmbH&Co.

The iodine catalyzed one-pot two-step oxidative system for cyclization of primary alcohols with o-aminobenzamides to quinazolinones using DMSO as the oxidant has been achieved, providing a convenient and efficient method for the synthesis of quinazolinones in good to excellent yields via in situ oxidation of primary alcohols to aldehydes. The reaction was carried out in the green solvent DMC, under atmospheric conditions. The procedure is suitable for aromatic or alkyl primary alcohols. © The Royal Society of Chemistry 2013.

In this paper, the mulberry fibers were successfully obtained by a new pretreatment named alkali-assisted microwave plus biological enzymatic technique (AMBET). The morphology, microstructure, physico-mechanical and antibacterial properties of the mulberry bast fibers were investigated by means of scanning electron microscope (SEM), Fourier Transform-Infrared (FTIR), differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), X-ray diffraction (XRD), instron tensile tester and antibacterial testing. The results showed that impurities of the bast fibers could be removed by AMBET treatment. AMBET treated mulberry fiber was even, smooth and fine, and typical cellulose I in the mulberry fibers was confirmed by FTIR and XRD analysis. The crystallinity of the AMBET treated fibers was higher than that of the raw mulberry and chemical treated mulberry fibers. Thermal analysis indicated that the mulberry fibers had a good thermal stability. Moreover, the AMBET treated mulberry fibers showed excellent antimicrobial activities against S. aureus. The physical properties of the mulberry fibers indicated the AMBET treated mulberry fibers were ideal candidates for new textile materials. © 2011 The Korean Fiber Society and Springer Netherlands.

Study the influence of eri-silk degumming process for degumming results of 2709 alkaline protease; combined with the orthogonal experimental analysis of high degumming rate and breaking strength of the best eri-silk degumming process, and then compare the optimized extracted eri-silk with mulberry silk, virgin silk, cotton, wool and ramie fibers for their fineness, mechanical properties, and friction performance comparison. The results show that the 2709 alkaline protease can effectively remove silkgum, and that the amount of enzyme is the main factor affecting degumming rate; pH value is the main factors for the breaking strength. Comparing with other fibers, eri-silk's average fineness is smaller, breaking strength and initial modulus tend to be larger, but their coefficient of variation also tend to be larger. Besides, eri-silki's breaking elongation is not as good as wool and silk, but better than other fibers. Natural silk's dynamic and static coefficient of tangential impedance is lower in comparison with other natural fibers. Ramie has the largest tangential resistance factor. Among the natural silks, the eri-silk's tangential impedance coefficient is greater than tussah and smaller than mulberry silk. © (2014) Trans Tech Publications, Switzerland.
