GC Smart 结合HS-10 法测定医用纱布中环氧乙烷残留
关键字：HS-10
本文利用岛津公司 HS-10 顶空自动进样器，结合 GC Smart 气相色谱仪，建立了医用纱布中环氧乙烷残留的测定方法。在 0.2~10 μg 标准曲线浓度范围内线性关系良好，相关系数 R为 0.9991，峰面积重现性良好，0.4 μg 标准样品连续测定 6 次，RSD 为 2.64%。在 0.4 μg/g 加标水平下样品平均加标回收率为 89.4%。该方法可用于医用纱布中环氧乙烷残留的快速定性定量测定。

[Macromol. Chem. Phys.] Fast and Green Synthesis of a Smart Glyco-surface via Aqueous Single Electron Transfer-Living Radical Polymerization
Facile synthesis of a silicon surface modified by poly(N-isopropylacrylamide-co-N-acryloyl glucosamine) [poly(NIPAAm-co-AGA)] brushes prepared by surface-initiated single electron transfer-living radical polymerization (SET-LRP) in water is described. The copolymerization exhibits a fast polymerization rate and good controllability. Moreover, copolymers with variable AGA content and comparable t...

Construction of Small-Diameter Vascular Graft by Shape-Memory and Self-Rolling Bacterial Cellulose Membrane
关键字：Bacterial Cellulose Membrane
Bacterial cellulose (BC) membranes with shape-memory properties allow the
rapid preparation of artificial small-diameter blood vessels when combined
with microfluidics-based patterning with multiple types of cells. Lyophilization
of a wet multilayered rolled BC tube endows it with memory to recover
its tubular shape after unrolling. The unrolling of the BC tube yields a flat
membr...

Changing the shape of chromophores from “H-type” to “star-type”: increasing the macroscopic NLO effects by a large degree
关键字：star-type, NLO polymer
In this paper, an NLO polymer P2, consisting of “star-type” chromophore, was first prepared through the Suzuki coupling reaction and the Sonogashira coupling reaction. For comparison, its “H-shape” analogue P1, only consisting of an “H-type” chromophore, was synthesized. To further enhance the NLO coefficient and stability, the “star-type” chromophore was also introduced into hyperbranched...
