44. X-ray crystallographic structure of cyclic tetramer ester based on bisphenol-A and o-phthaloyldichloride. Jiang HY, Liu TX, Zhang HF, Chen TL, Mo ZS. POLYMER 37 (15): 3427-3429 JUL 1996.
The polycrystalline powder of the cyclic tetramer ester based on bisphenol-A and o-phthaloyldichloride has been prepared by recrystallization from nitrobenzene and its crystal structure determined by wide-angle X-ray diffraction. The unit cell is orthorhombic and has dimensions a=0.967 nm, b=0.8699 nm, c = 2.0859 nm. With two tetramers per unit cell, the crystal density is 1.36 g cm(-3). Indices o...

6. A processing-induced clay dispersion and its effect on the structure and properties of polyamide 6. Liu TX*, Tjiu WC, He CB, Na SS, Chung TS. POLYMER INTERNATIONAL 53 (4): 392-399 APR 2004.
The nanostructures and morphologies of polyamide 6 (PA6)/organoclay nanocomposites prepared by melt compounding have been studied by using X-ray diffiraction (XRD) and transmission electron microscopy (TEM). A combination of XRD and TEM indicates that an exfoliated clay morphology dominates at low clay loadings (less than or equal to5wt%) and a mixture of intercalated and exfoliated structures exi...

5. Polymer nanocomposites using urchin-shaped carbon nanotube-silica hybrids as reinforcing fillers. Zhang WD*, Phang IY, Shen L, Chow SY, Liu TX*. MACROMOL. RAPID COMMUN. 25 (21): 1860-1864, 2004.
Carbon nanotubes (CNTs) have been grown on MCM-41 supported Fe nanoparticles and the as-prepared (no further purification) CNT-silica hybrid was directly incorporated into nylon-6 (PA6) by simple melt-compounding. The urchin-shaped CNT-silica hybrid filler was observed to be homogeneously dispersed throughout the matrix by scanning 1 electron and transmission electron microscopy. Compared with nea...

生物可降解的氧化锌纳米载体：体外酸度控制阿霉素释放
关键字：Zn0@ polymer-DOX，细胞毒性，药物释放
本文采用两步共聚法合成了荧光颜色可调的水溶性Zn0@ polymer核壳结构量子点并用于阿霉素的载药和释放。直径为3 nm的Zn0@ polymer可以负载DOX形成Zn0@ polymer- DOX纳米复合物。Zn0@polymer的水溶液在紫外灯照射下的荧光为绿色，其量子产率接近40%。而Zn0@ polymer-DOX水溶液的紫外吸收光谱及荧光光谱表现出了二者的混合特征，说明纳米晶体混合物中的Zn0@ polyme...

Proof of the identity between the depletion layer thickness and half the average span for an arbitrary polymer chain
关键字：平均跨度，耗散层厚度，体积排除效应，刚性平面
The confinement analysis from bulk structure (CABS) approach [Y. Wang et al., J. Chem. Phys. 128, 124904 (2008)] is extended to determine the depletion profiles of dilute polymer solutions confined to a slit or near an inert wall. We show that the entire spatial density distributions of any reference point in the polymer chain (such as the center of mass, middle segment, and end segments) can be c...
