It may be caused by that pre-cross-linking process developed a net structure previously keeping more great molecules of vancomycin inside microspheres.

Complex networks, using the methods of graph theory and statistical physics, can reveal the evolutionary mechanisms of systems and their evolutionary laws (structure) and modes of action (function).
S-curve is widely used in economics, politics, population statistics, chemistry, plant population dynamics, insect ecology and forest growth.

Application of Dissolved Wool Keratin in Anti-pilling Processing Jiru Jia1, Jinbo Yao2,*, Jianyong Liu1, Yanbo Liu3 1School of Textiles, Tianjin Polytechnic University, Tianjin 300387 China 2School of Chemistry and Chemical Engineering, Wuhan Textile University, Wuhan, 430073 China 3School of Textile Science and Engineering, Wuhan Textile University, Wuhan, 430073 China * Corresponding author: Jinbo Yao; Email: jinboyao1964@wtu.edu.cn Keywords: Wool dissolving system, LKZ-610, keratin solution, antipilling cashmere fabric, hand.
Keratin solution is featured with nontoxicity and skin affinity, the macromolecules of which has a structure similar to cashmere fiber, capable of forming a layer of protein membrane on fiber surface, and thus decreasing surface friction characteristics, enhancing the antipilling property of the corresponding fabric.

The characteristic peak at 3290 cm-1 and 1732 cm-1 denote the presence of hydroxyl and carboxyl bands in the structure respectively.

Fourier transform infrared (FTIR) spectroscopy combined with attenuated total reflection (ATR) is effective determination method for molecular structure and content of components with the simplicity, speed and suitable for use in rapid or on-line measurements, which had been widely applied to many fields [1-6].

Here N(t) is the number of 18O atoms entering the sample on its unit area throughout the annealing time by diffusion in the regular lattice and over the nanoboundary network; a is a period (or a diameter) of the structure with a coarse boundary network.

The chemistry and homogeneity of the alloy was determined by analysing in a CAMECA SX100 electron probe micro analyser (EPMA) and was confirmed to be having homogenous composition of Cu-10 at. % Al.
These pieces were encapsulated in quartz tubes in He atmosphere at a residual pressure of about 16 kPa and annealed at 1223 K for 72 h to homogenise the materials and to form stable coarse grained structure, which reduces the contribution of grain boundary diffusion in the diffusion annealing stage.

The twin structure manifests itself in the X-ray topographs as areas of black or white contrast (Fig. 1), which becomes reversed as the crystal is rotated by 60o around the [111] axis [1].

The CSD-Gel-PCL 5% specimen showed lamellar structure on the surface of composite.
