Diameters of single-walled carbon nanotubes (SWCNTs) and related nanochemistry and nanobiologyFrontiers of Materials Science in China - Tập 4 - Trang 17-28 - 2009
Jie Ma, Jian-Nong Wang, Chung-Jung Tsai, Ruth Nussinov, Buyong Ma
We reviewed and examined recent progresses related to the nanochemistry and nanobiology of signal-walled carbon nanotubes (SWCNTs), focusing on the diameters of SWCNTs and how the diameters affect the interactions of SWCNT with protein and DNA, which underlay more complex biological responses. The diameters of SWCNTs are closely related to the electronic structure and surface chemistry of SWCNTs, ...... hiện toàn bộ
In vivo study of degradable magnesium and magnesium alloy as bone implantFrontiers of Materials Science in China - Tập 1 - Trang 405-409 - 2007
Jingjing Huang, Yibin Ren, Yue Jiang, Bingchun Zhang, Ke Yang
In order to investigate the in vivo behavior of pure magnesium and AZ31B and the influence of mineralization induction ability, sample rods were implanted intramedullary into the femora of rabbits. After one and nine weeks, six animals from each group were sacrificed, respectively. Undecalcified cross-sections of implant were performed to observe bone-implant by scanning electron microscopy (SEM) ...... hiện toàn bộ
Thermal degradation behavior and kinetic analysis of poly(L-lactide) in nitrogen and air atmosphereFrontiers of Materials Science in China - Tập 4 - Trang 78-83 - 2010
Ming-Tao Run, Xin Li, Chen-Guang Yao
The non-isothermal and isothermal degradation behaviors and kinetics of poly(L-lactide) (PLLA) were studied by using thermogravimetry analysis (TGA) in nitrogen and air atmosphere, respectively. At lower heating rate ((5–10)°C/min), PLLA starts to decompose in air at lower temperature than those in nitrogen atmosphere; however, at higher heating rate ((20–40)°C/min), the starting decomposition tem...... hiện toàn bộ
Swelling behaviors, tensile properties and thermodynamic interactions in APS/HEMA copolymeric hydrogelsFrontiers of Materials Science in China - Tập 1 - Trang 427-431 - 2007
Zhihui Lin, Wenhui Wu, Jianquan Wang, Xin Jin
A series of hydrogels was synthesized from hydrophobic allyl phenyl sulfone (APS) and hydrophilic 2-hydroxyethyl methacrylate (HEMA) by bulk free radical copolymerization. The effects of APS content and temperature were studied on network parameters such as effective crosslink density (v
e), molar mass between crosslinks (M
c) and polymer-water interaction parameter...... hiện toàn bộ
The effect of HfO2 second phase in Fe films upon ion irradiationFrontiers of Materials Science in China - Tập 4 - Trang 193-196 - 2010
Na Zhang, Zheng-Cao Li, Zheng-Jun Zhang
Ferrum of BCC crystal structure is a typical kind of matrix in structural alloy steels which could be strengthened by introducing some second phase. In the present study, BCC Fe thin films with hafnium oxide (HfO2) second phase have been synthesized in an electron beam evaporation system. Multi-layered and glancing angle deposition (GLAD) techniques were taken to form some HfO2 second phase in Fe ...... hiện toàn bộ
Electron beam irradiated HDPE/EVA/Mg(OH)2 composites for flame-retardant electric cablesFrontiers of Materials Science in China - Tập 2 - Trang 426-429 - 2008
Hui Liu, Nabil A. Noman Alkadasi, Yan Zhu, Li-fang Tong, Zheng-ping Fang, Yong-chang Wang
The mechanical properties and flammability of high-density polyethylene (HDPE)/ethylene vinyl acetate (EVA) mixed with various amounts of magnesium hydroxide (Mg(OH)2) as the filler in composites, irradiated with electron beam at an irradiation dose of 150 kGy, have been studied. It is found that high-energy electron beam irradiation has significant effects on the mechanical properties of the HDPE...... hiện toàn bộ
Preparation of paclitaxel-loaded microspheres with magnetic nanoparticlesFrontiers of Materials Science in China - Tập 1 - Trang 383-387 - 2007
Sheng Cui, Xiaodong Shen, Ruihua Shi, Benlan Lin, Ping Chen
The objective of this paper was to prepare paclitaxel-loaded microspheres, a kind of target-orientation anticancer drug. The paclitaxel-loaded microspheres were prepared with magnetic Fe3O4 nanoparticles and taxol. The morphology was characterized by scanning electron microscopy (SEM), and the average size and the size distribution were determined by a laser-size distributing instrument. High perf...... hiện toàn bộ
