Using the finite-difference time-domain(FDTD) method,we simulate the coupling between a gold nanorod and gold nanoparticles with different plasmonic resonant frequencies/volumes as well as that between the nanorod and a dielectric nanosphere.The influences of coupling with different nanoparticles on the excitation of…
A new type counter electrode for dye-sensitized solar cells (DSCs) was proposed which consists of substrate, aluminum film and platinum film. The new type counter electrode can obviously improve the photoelectric conversion efficiency of DSCs from 3.46% to 7.07% under the standard AM1.5 irradiation condition. Advantag…

Ti-Modified (Na0.5K0.5)(TixNb1-x)O3 (NKNT) piezoelectric ceramics were fabricated by double-layer buried powder process at 1020°C for 2 h. The microstructures,and piezoelectric and dielectric properties of the lead-free NKNT ceramics were investigated. X-ray diffraction re-sults indicated that Ti4+ had diffused into t…
The existing form and grain refining effects of small zirconium addition in pure Mg, Mg-Yb and Mg-Zn binary alloys, and Mg-Zn-Yb ternary alloy (ZK60-Yb) were investigated. The results show that Zr element exists mainly in single and cluster particles of pure α-Zr or Zn-Zr compounds inside grains and at grain boundarie…

Chemieal characteristies of the gelatinous sheath produced by the three MLti,guggyE:ti speeies wh!ch constitute waterbloom in Lake suwa were investigated from an eeologieal standpoint, The outlook and solubiUty of the gelatinous sheath were different among ij. aeru inosa, ij. viridis and M. weseBbey ii, though the mai…
To avoid intergranular corrosion and obtain microstructural homogenization,the conventional SUS304 austenitic stainless steel needs to be solution annealed after hot rolling.This study investigates the thermal-mechanical controlled process (TMCP) of SUS304 steel,especially the controlled rolling and online accelerated…
价值比从相应一步舞综合体的那些显著地长，显示为二拍子的圆舞共聚物完成的更多的短而粗的结构。相应于在微观结构的这差别，二拍子的圆舞共聚物是半水晶的，当一步舞共聚物是完全非结晶的时。在结论， P (LA-co-PDO ) 共聚物的 crystallinity 能方便地被调整由经由不同聚合线路改变共聚物的微观结构遇见特定的应用。
This paper presents a genetic-based approach to correct the parameters for single-phase induction motors in various supply voltage levels. From conventional tests, electrical (resistances and induc...
Since the first microporous zinc phosphates with zeolite-like topologies were reported by Gier and Stucky,it has attracted much attention from chemists and materials scientists due to their chemical and physical properties and the applications as catalysts,nonlinear optical materials and ion exchangers,etc.. With a vi…
A new electrochemical sensor for ATP with synthetic cyclophane stably attached onto single-walled carbon nanotubes (SWNTs) as the recognition elements is described. UV-vis and cyclic voltammetric results demonstrate that ATP may interact with the synthetic cyclophane recognition elements to form a stable adduct mainly…
Spectroscopic studies have revealed that the amount of polyureas formed and the kinetics of their formation in soy based polyurethane systems are considerably different from traditional systems employing ethylene oxide-propylene oxide (EO-PO) based polyols.The aggregation of polyureas was characterized by the hydrogen…
Single-crystalline W5O14 nanorods were prepared by plasma arc gas condensation with assistance of blowing gas.The gas sensing property of W5O14 nanorods was further investigated.The results show that 10% hydrogen added into argon as plasma gas leads to the formation of W5O14 nanorods prepared under the current of 90 A…

The melilite-type Ca2-xSrxZnSi20, ceramics were synthesized by solid state ceramic route. The lattice parameters and cell volume increased with increasing the composition x, The substitution of Sr for Ca has improved the microwave dielectric properties. Excellent dielectric properties (&r = 8.4, Quxf = 105000 GHz (at…
A laboratory lysimeter experiment was conducted to investigate the effects of forage corn (Zea mays L.) stalk application on the CO2 concentration in soil air and calcareous sodic soil reclamation. The experimental treatments tested were soil exchangeable sodium percentage (ESP) levels of 1, 11, and 19, added corn sta…
B-ZSM-5 zeolites with different crystal sizes were synthesized by adjusting hydrothermal synthesis temperature.Ti-ZSM-5 samples were prepared by gas-solid reaction using acid-treated B-ZSM-5 as precursors with gaseous TiCl4.The samples were characterized by scanning electron microscopy(SEM),X-ray powder diffraction(XR…

The high-resolution imaging of vWF multimers with main- and accessory bands over the extreme range of protein size from 556 kDa homodimer to over 20,000 kDa multimers requires particular optimization of the electrophoresis technique. Only few laboratories are skilled to perform this analysis. Most critical points of M…
