According to literature there are few and very old investigations about the relationship between high performance yarn twist, which are very used in technical textiles, and its mechanical properties. Therefore, this study aims to determine the influence of twist on the tensile strength, elongation and tenacity of thre…
Nanoparticles 为 bioimaging 和 biolabeling 应用有庞大的潜力，在哪个常规有机性地基于荧光灯标签降级并且没能提供长期的追踪。因此，途径的开发做荧光灯可溶的探针水和标签房间有效为很生物的应用程序是合乎需要的。这里，我们为蛋白质标记作为一根探针从 3-aminopropyltriethoxysilane (APTES ) 在自我装配的 nanodots (沙) 的制造和描述上报导。我们显示出那荧光灯沙探针在水的环境展出明亮的光致发光和 biocompatibility。在用 hepatoma 房间线标记的蛋白质和糖类的 vitro 成像选择用分别地与卵白素和半乳糖结合的 biocompatible…
2 Mg 3 Zn 3 )阶段也不 S (艾尔 2 CuMg )阶段在当演员组合金发现。计算阶段部件根据 Scheil 模型的意见与试验性的结果一致。在在 460 点的 homogenization 期间
Fe3O4 is an attractive conversion reactionbased anode material with high theoretical capacity(928 mA h g-1).However,the poor cycling and rate performance hinder its applications in Li-ion batteries.In this work,we report an effective strategy to synthesize threedimensionally macroporous graphene-supported Fe3O4hybrid…
A simple hydrothermal process followed by heat treatment was applied to the preparation of spinel Li1.05Mn1.95O4. In this process, electrolytic manganese dioxide(EMD) and LiOH·H2O were used as starting materials. The physiochemical properties of the synthesized samples were investigated by thermogravimetry-differentia…
The ultra-low density wood-based foaming material(ULDM),density in 0.03~0.09g·cm-3, was prepared by liquid foaming process.Four inorganic components were used as fire retardants to prepare flame retardant ULDM,including boron,nitrogen-phosphorus,silicon and halogen type.By means of cone calorimeter,the ULDM were syste…
To optimize the existing slurry for abrasive-free polishing(AFP)of hard disk substrate,a water-soluble free radical initiator,2,2-azobis[2-(2-imidazolin-2-yl)propane]dihydrochloride(AIBI)is introduced to the H2O2-based slurry.The polishing results show that,the material removal rate(MRR)of hard disk substrate polished…
ZrN- SiAlON composite materials were synthesized at 1 550 ℃ for 6 h via a carbothermal reduction nitridation route using fly ash( ≤74 μm),zircon( ≤44 μm)and active carbon as starting materials. The processed ZrN- SiAlON composite micropowders were mixed with polyvinyl alcohol as binder to prepare ZrN( ZrON)-SiAlON com…
Computer simulation with Monte Carlo is an important tool to investigate the function and equilibrium properties of many biological and soft matter materials solvable in solvents.The appropriate treatment of long-range electrostatic interaction is essential for these charged systems,but remains a challenging problem f…
银 nanoparticles (AgNPs ) 的物理、化学、生物化学的性质在很大程度上取决于他们位于他们的表面的尺寸，形状，尺寸分发，和 stabilizers。这研究集中了于二典型 stabilizers，也就是柠檬酸盐(市民) ，由静电的排斥保护 nanoparticles 的低分子的离子，和 polyvinylpyrrolidone (PVP ) ，由位的稳定保护 nanoparticles 的吸水的、中立、高分子的聚合物。自然 bacterioplankton 从发育营养正常促进剂被收集，闹市区湖并且暴露了 AgNPs-PVP 和 AgNPs 市民的集中(0.15 mg/L ) 到五。回答在暴露的 1， 3， 5 和…
A composite coating with inner and outer layers was prepared for the thermal protection of woven silica fiber fabrics. Using a sol mixture of a silica sol and AlF3/SiO2 particles mixed in the stoichiometric molar ratio for mullite,hollow silica spheres and short mullite fibers were added to the inner layer and outer l…
The vapor phase equilibrium analysis has been carried out for the Sb–S–O–H quarternary system using a Constrained Chemical Potential Method (CCPM). A total 24 species in vapor phase and 9 condens able constituents have been considered. The resulting data for the system have been plotted on Gibbs triangles as a functio…
Calixarene liquid crystals were important part among calixarene derivatives. The synthesis and mesomorphic properties of all kinds of calixarene liquid crystala have been discussed and reviewed. There are two methods to prepare calixarene liquid crystals. One way is to introduce the corre- sponding functional groups w…
