The experimental results indicated that the Raman spectroscopy, interface impedance, electron transport and recombination…
A theoretical formalism based on mode-coupling theory( MCT) was established to study the longtime diffusion coefficient of nanoparticles in polyelectrolyte solutions. By introducing an approximate summation form for Γpp( k,t),Dmicrocan be calculated straightforwardly and it is necessary to investigate explicitly how D…
To observe the feasibility of the removal of carmine, peanut husk, an agriculture by-product, was crosslinked with epichlorohydrin in alkaline medium and used for adsorption of carmine from aqueous solution. Batch experiments were carried out to study the effects of various parameters such as initial pH, contact time,…
Tensile tests of GH4169 alloy were performed at room temperature. Different fractions, distributions and shapes of δ phase was prepared by aging treated at 880 °C, 930 °C and 980 °C for 5 h or 10 h. The effect of δ phase on the mechanical properties of GH4169 alloy was investigated. The results show that 0.2% yield st…

Seperti batu mulia lainnya, seperti jesper, amethyst, topaz, jade and onyx, Agate pada umumnya memiliki komposisi kimia SiO2. Batuan y…
An Al2O3P/Al composite was successfully synthesized using a displacement reaction between 80 wt% Al and20 wt% Cu O powders at a heating rate of 5 °C/min. Two different sizes Cu O particles were used, and all the experiments were conducted under an argon atmosphere. To analyze the microstructural evolution during synth…
Using the low-energy effective Hamiltonian of the ABC-stacked multilayer graphene, the pseudo-spin coupling to real orbital angular momentum of electrons in multilayer graphene is investigated. We show that the electron wave function in N-layer graphene mimics the behavior of a particle with a spin of N ×( /2), where…
Layered cathode materials of high-temperature lithium batteries, Li Ni1/3Mn1/3Co1/3O2 are synthesized by a sol-gel method with variation in final sintering temperature for borehole applications. The structure, morphology and high-temperature discharge performance of these resulting products are investigated by X-Ray D…
骨胶原纤维提供成为强壮的一个好例子微 -- 或从 nanoscale tropocollagen 分子通过的 mesoscale 纤维一蹒跚并且以一种自底向上的方式的 cross-linked 组织。骨胶原纤维的建筑上的特征被显示出是一条有希望的途径开发高效的碳 nanotube (CNT ) 纤维的 Mimicking。在现在的工作，一个有弹性的模型被开发在 bioinspired CNT 捆以内描述负担转移和失败繁殖，并且与象 CNT 方面比率和纵的差距那样的很多个几何、物理的参数建立捆的机械性质的关系，接口交叉结合密度，和在 CNT 的 导致functionalization 的降级，等等。与模型一起，沿着 CNTCNT 接…
Two kinds of important equipment i.e. selective catalytic reduction system(SCR) and flue gas cooler are applied in coal-fired power plant to achieve energy conservation and to reduce emission. However, few studies have been published on the influence of ammonia escaped from SCR system on flue gas cooler. In this study…

二维的英尺红外关联光谱学被用来揭示 isotactic 的结构的变化聚丙烯(iPP ) mesophase 在加热过程期间。在 iPP 的常规螺旋状的乐队之中的合作关系根据同步光谱被讨论。结果证明有不同长度螺旋的片断被发现在 25 –60  的温度范围经历一个混乱过程； °C。
High-resolution transmission electron microscopy(HRTEM) and X-ray diffraction(XRD) were used to investigate Ni segregation and thermal stability of reversed austenite(RA) in a Fe–Ni alloy processed by quench–lamellarize–temper(QLT) heat treatment. The results show that the 77 K impact energy of the alloy increases wit…
可混和性，等温的结晶化动力学，和形态学 poly (L 减水乳酸)/poly (trimethylene 碳酸盐)(PLLA/PTMC ) 水晶 / 非结晶的混合被微分扫描热量测定(DSC ) 和光显微镜学(OM ) 学习。OM 图象和未改变的玻璃转变温度的异质证明 PLLA 与 PTMC 是不能混合的。在等温的结晶化期间，当 PTMC 内容是低的时， PLLA 的结晶化率改善了(20%) 。然而，当 PTMC 内容是高度(30%) 时，结晶化率显著地减少了。在水晶动力学的这些非线性的变化的原因被加热舞台的一台显微镜的优点根据成核和生长过程分析。混合的等温的结晶化形态学被极化的光显微镜学也学习，结果证实了从结晶化动力学获得的结论。
